Basis of Presentation | BASIS OF PRESENTATION Nature of Business Pixelworks designs, develops and markets video processing semiconductors, intellectual property cores, software and custom ASIC solutions for high-quality energy efficient digital video applications. Our products enable our customers to deliver the highest energy efficient video quality on their devices. Our core video display processing technology intelligently processes video signals from a variety of sources and optimizes the image for the viewer. The rapid growth in video-capable consumption devices, especially mobile, has increased the demand for video display processing technology in recent years. Our technologies can be applied to a wide range of devices from large-screen projectors to low power mobile tablets and smartphones. Our products are architected and optimized for power, cost, bandwidth, and overall system performance, according to the application requirements. Our primary target markets include digital projection systems, tablets, and smartphones. As of December 31, 2016, we had an intellectual property portfolio of 148 patents related to the visual display of digital image data. We focus our research and development efforts on developing video algorithms that improve quality, and architectures that reduce system power, cost, bandwidth and increase overall system performance and device functionality. We seek to expand our technology portfolio through internal development and co-development with business partners, and we continually evaluate acquisition opportunities and other ways to leverage our technology into other high-value markets. Pixelworks was founded in 1997 and is incorporated under the laws of the state of Oregon. Our consolidated financial statements include the accounts of Pixelworks and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. All foreign subsidiaries use the U.S. dollar as the functional currency, and as a result, transaction gains and losses are included in the consolidated statements of operations. Transaction losses were $153 , $125 and $159 for the years ended December 31, 2016, 2015 and 2014, respectively. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, product returns, warranty obligations, bad debts, inventories, property and equipment, impairment of long-lived assets, valuation of share-based payments, income taxes, litigation and other contingencies. The actual results experienced could differ materially from our estimates. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents We classify all cash and highly liquid investments with original maturities of three months or less at the date of purchase as cash and cash equivalents. Cash equivalents, which consist of U.S. denominated money market funds totaled $17,960 and $25,343 as of December 31, 2016 and 2015 , respectively. Accounts Receivable Accounts receivable are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. At the end of each reporting period, we estimate the allowance for doubtful accounts based on an account-by-account risk analysis of outstanding receivable balances. The determination to write-off specific accounts receivable balances is made based on the likelihood of collection and past due status. Past due status is based on invoice date and terms specific to each customer. Inventories Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value). Property and Equipment Property and equipment are stated at cost. Depreciation and amortization is calculated on a straight-line basis over the estimated useful life of the assets which are generally as follows: Software Lesser of 3 years or contractual license term Equipment, furniture and fixtures 2 years Tooling 2 to 4 years Leasehold improvements Lesser of lease term or estimated useful life The cost of property and equipment repairs and maintenance is expensed as incurred. Licensed Technology We have capitalized licensed technology assets in other long-term assets. These assets are stated at cost and are amortized on a straight-line basis over the term of the license or the estimated life of the asset, if the license is not contractually limited, which is generally two to five years. Useful Lives and Recoverability of Equipment and Other Long-Lived Assets We evaluate the remaining useful life and recoverability of equipment and other assets, including identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value. Revenue Recognition We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed and determinable, and collection is reasonably assured. For product sales, we require customers to provide purchase orders prior to shipment and we consider delivery to occur upon shipment provided title and risk of loss have passed to the customer based on the shipping terms. These conditions are generally satisfied upon shipment of the underlying product. There are no customer acceptance provisions associated with our products, and except for replacement of defective products under our warranty program discussed below, we have no obligation to accept product returns from end customers; however, we have accepted returns on a case-by-case basis as customer accommodations in the past. As a result, we provide for estimated reductions to gross profit for these sales returns in our reserve for sales returns and allowances. At the end of each reporting period, we estimate the reserve based on historical experience and knowledge of any applicable events or transactions. The reserve is included in accrued liabilities in our consolidated balance sheets. A portion of our sales are made to distributors under agreements that grant the distributor limited stock rotation rights and price protection on in-stock inventory. The stock rotation rights allow these distributors to exchange a limited amount of their in-stock inventory for other Pixelworks product. As a result, we provide for estimated reductions to gross profit for these stock rotations in our reserve for sales returns and allowances. At the end of each reporting period, we estimate the reserve based on historical experience and knowledge of any applicable events or transactions. The reserve is included in accrued liabilities in our consolidated balance sheets. On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Our license fee arrangements generally include multiple deliverables and we are required to determine whether there is more than one unit of accounting. To the extent that the deliverables are separable into multiple units of accounting, we allocate the total fee on such arrangements to the individual units of accounting using management’s best estimate of selling price ("ESP"), if third party evidence ("TPE") or vendor specific objective evidence ("VSOE") does not exist. We defer revenue recognition for consideration that is contingent upon future performance or other contractual terms. The Company's process for determining its ESP for deliverables without VSOE or TPE considers multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. The key factors considered by the Company in developing the ESPs include the nature and complexity of the licensed technologies, our cost to provide the deliverables, the availability of substitute technologies in the marketplace and the Company's historical pricing practices. We then recognize revenue for each unit of accounting depending on the nature of the deliverable(s) comprising the unit of accounting in accordance with the revenue recognition criteria mentioned above. Fees under these agreements generally include (a) license fees relating to our IP, (b) engineering services, and (c) support services. Historically, each of these elements have standalone value and therefore each are treated as separate units of accounting. Any future licensing arrangements will be analyzed based on the specific facts and circumstances which may be different than our historical licensing arrangements. For deliverables related to licenses of our technology that involve significant engineering services, we recognize revenue in accordance with the provisions of the proportional performance method. We determine costs associated with engineering services using actual labor dollars incurred and estimated other direct or incremental costs allocated based on the percentage of time the engineer(s) spent on the project. These costs are deferred until revenue recognition criteria have been met, at which time they are reclassified as cost of revenue. Warranty Program We warrant that our products will be free from defects in material and workmanship for a period of twelve months from delivery. Warranty repairs are guaranteed for the remainder of the original warranty period. Our warranty is limited to repairing or replacing products, or refunding the purchase price. At the end of each reporting period, we estimate a reserve for warranty returns based on historical experience and knowledge of any applicable events or transactions. The reserve for warranty returns is included in accrued liabilities in our consolidated balance sheets. Stock-Based Compensation We currently sponsor a stock incentive plan that allows for issuance of employee stock options and restricted stock awards, including restricted stock units. We also have an employee stock purchase plan for all eligible employees. The fair value of share-based payment awards is expensed straight-line over the requisite service period, which is generally the vesting period, for the entire award. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense. The fair value of our stock option grants and purchase rights under our employee stock purchase plan are estimated as of the grant date using the Black-Scholes option pricing model which is affected by our estimates of the risk free interest rate, our expected dividend yield, expected term and the expected share price volatility of our common shares over the expected term. The fair value of our restricted stock awards are based on the market value of our stock on the date of grant, adjusted for the effect of estimated forfeitures. Research and Development Costs associated with research and development activities are expensed as incurred, except for items with alternate future uses which are capitalized and depreciated over their estimated useful lives. On occasion, we enter into co-development arrangements with current or prospective integrated circuit ("IC") customers to defray a portion of the research and development expenses we expect to incur in connection with our development of an IC product. As amounts become due and payable without recourse under co-development agreements, they are offset against research and development expense up to the amount of related costs incurred. Income Taxes We account for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We establish a valuation allowance to reduce deferred tax assets if it is "more likely than not" that a portion or all of the asset will not be realized in future tax returns. An uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets. Accumulated Other Comprehensive Income Accumulated other comprehensive income, net of tax, consists of the following: December 31, 2016 2015 Actuarial income on foreign pension obligation $ 27 $ 28 Accumulated transition foreign pension obligation (17 ) (22 ) Accumulated other comprehensive income $ 10 $ 6 Fair Value of Financial Instruments See "Note 4: Fair Value Measurements" for information regarding accounting policies related to the fair value of our financial instruments. Risks and Uncertainties Concentration of Suppliers We do not own or operate a semiconductor fabrication facility and do not have the resources to manufacture our products internally. We rely on a limited number of foundries and assembly and test vendors to produce all of our wafers and for completion of finished products. We do not have any long-term agreements with any of these suppliers. In light of these dependencies, it is reasonably possible that failure to perform by one of these suppliers could have a severe impact on our results of operations. Additionally, the concentration of these vendors within Taiwan, the People’s Republic of China and Singapore increases our risk of supply disruption due to natural disasters, economic instability, political unrest or other regional disturbances. Risk of Technological Change The markets in which we compete, or seek to compete, are subject to rapid technological change, frequent new product introductions, changing customer requirements for new products and features, and evolving industry standards. The introduction of new technologies and the emergence of new industry standards could render our products less desirable or obsolete, which could harm our business. Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents and accounts receivable. We limit our exposure to credit risk associated with cash equivalent balances by holding our funds in high quality, highly liquid money market accounts. We limit our exposure to credit risk associated with accounts receivable by carefully evaluating creditworthiness before offering terms to customers. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Shared-Based Payment Accounting ("ASU 2016-09"). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements, for example, an accounting policy election may be made to account for forfeitures as they occur, rather than based on an estimate of future forfeitures. In addition, under previous guidance, excess tax benefits and deficiencies from stock-based compensation arrangements were recorded in equity when the awards vested or were settled. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies in the income statement. The standard is effective for the Company on January 1, 2017. We do not expect the adoption of this update to have a material impact on our financial position, results of operations, or cash flows. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use (ROU) asset and a corresponding lease liability. For finance leases the lessee would recognize interest expense and amortization of the ROU asset and for operating leases the lessee would recognize a straight-line total lease expense. ASU 2016-02 will become effective for the Company on January 1, 2019. While we are currently assessing the impact ASU 2016-02 will have on our financial statements, we expect the primary impact to our financial position upon adoption will be the recognition, on a discounted basis, of our minimum commitments under noncancelable operating leases on our consolidated balance sheets resulting in the recording of right of use assets and lease obligations. Our current minimum commitments under noncancelable operating leases are disclosed in "Note 7: Commitments and Contingencies". In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11"), which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU 2015-11 is effective prospectively and is effective for the Company on January 1, 2017, with early adoption permitted. We do not expect the adoption of this update to materially impact our financial position, results of operations, or cash flows. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which requires that an entity recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 allows for either full retrospective or modified retrospective adoption and will become effective for the Company on January 1, 2018. We have developed an implementation plan to adopt this new guidance. As part of this plan, we are currently assessing the impact of the new guidance on our results of operations. Based on our procedures performed to date, nothing has come to our attention that would indicate that the adoption of ASU 2014-09 will have a material impact on our financial statements, however, we will continue to evaluate this assessment in 2017. We intend to adopt ASU 2014-09 on January 1, 2018. We have not yet selected a transition method, but expect to do so in 2017 upon completion of further analysis. |

Depreciation and amortization expense for equipment, furniture, fixtures, tooling and leasehold improvements was $1,705 , $1,483 and $1,293 for the years ended December 31, 2016, 2015 and 2014, respectively. Other Assets, Net Other assets consist primarily of deposits, deferred tax assets and licensed technology. Amortization of licensed technology was $6 , $653 and $939 for the years ended December 31, 2016, 2015 and 2014, respectively. Accrued Liabilities and Current Portion of Long-Term Liabilities Accrued liabilities and current portion of long-term liabilities consist of the following: December 31, 2016 2015 Accrued commissions and royalties $ 2,427 $ 2,220 Accrued payroll and related liabilities 2,169 2,419 Accrued interest payable 2,078 1,754 Current portion of accrued liabilities for asset financings 389 1,241 Accrued costs related to restructuring 60 — Reserve for warranty returns 28 49 Other 709 845 Accrued liabilities and current portion of long-term liabilities $ 7,860 $ 8,528 The following is a summary of the change in our reserve for warranty returns: Year Ended December 31, 2016 2015 2014 Reserve for warranty returns: Balance at beginning of year $ 49 $ 105 $ 329 Provision (benefit) 6 (24 ) (195 ) Charge-offs (27 ) (32 ) (29 ) Balance at end of year $ 28 $ 49 $ 105 Short-Term Line of Credit On December 21, 2010, we entered into a Loan and Security Agreement with Silicon Valley Bank (the "Bank"), which was later amended on December 14, 2012, December 4, 2013, December 18, 2015 and December 15, 2016 (as amended, the "Revolving Loan Agreement"). The Revolving Loan Agreement provides a secured working capital-based revolving line of credit (the "Revolving Line") in an aggregate amount of up to the lesser of (i) $10,000 , or (ii) $1,000 plus 80% of eligible domestic accounts receivable and certain foreign accounts receivable. The Revolving Line has a maturity date of December 29, 2017. In addition, the Revolving Loan Agreement provides for non-formula advances of up to $10,000 which may be made solely during the last five business days of any fiscal month or quarter and which must be repaid by the Company on or before the fifth business day after the applicable fiscal month or quarter end. Amounts advanced under the Revolving Line bear interest at an annual rate equal to the lender's prime rate plus 0.25% . The Revolving Loan Agreement, as amended also provides an option for LIBOR advances that bear interest based on the LIBOR rate. Interest on the Revolving Line is due monthly, with the balance due on December 29, 2017, which is the scheduled maturity date for the Revolving Line. The Revolving Loan Agreement, as amended contains customary affirmative and negative covenants, including with respect to the following: compliance with laws, provision of financial statements and periodic reports, payment of taxes, maintenance of inventory and insurance, maintenance of operating accounts at the Bank, the Bank's access to collateral, formation or acquisition of subsidiaries, incurrence of indebtedness, dispositions of assets, granting liens, changes in business, ownership or business locations, engaging in mergers and acquisitions, making investments or distributions and affiliate transactions. The covenants also require that the Company maintain a minimum ratio of qualifying financial assets to the sum of qualifying financial obligations. The Revolving Loan Agreement, as amended also contains customary events of default, including the following: defaults with respect to covenant compliance, the occurrence of a material adverse change, the occurrence of certain bankruptcy or insolvency events, cross-defaults, judgment defaults and material misrepresentations. The occurrence of an event of default could result in the acceleration of the Company's obligations under the Revolving Loan Agreement, as amended and an increase to the applicable interest rate, and would permit the Bank to exercise remedies with respect to its security interest. To secure the repayment of any amounts borrowed under the Revolving Loan Agreement, as amended, the Company granted to the Bank a security interest in substantially all of its assets, excluding its intellectual property assets. The Company has agreed not to pledge or otherwise encumber its intellectual property assets without prior written permission from the Bank. As of December 31, 2016, we had no outstanding borrowings on the Revolving Line. Short-term borrowings outstanding under the Revolving Line as of December 31, 2015 consisted of a non-formula advance of $3,000 which was repaid within required terms. The weighted-average interest rate on short-term borrowings outstanding as of December 31, 2015 was 3.75% . |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value: Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities. Level 2: Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions. The following table presents information about our assets measured at fair value on a recurring basis in the consolidated balance sheets as of December 31, 2016 and 2015: Level 1 Level 2 Level 3 Total As of December 31, 2016: Money market funds $ 17,960 $ — $ — $ 17,960 As of December 31, 2015: Money market funds $ 25,343 $ — $ — $ 25,343 We primarily use the market approach to determine the fair value of our financial assets. The fair value of our current assets and liabilities, including accounts receivable and accounts payable approximates the carrying value due to the short-term nature of these balances. We have currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with U.S. GAAP. |

Restructuring and Related Activities [Abstract] | |
Restructuring | RESTRUCTURING In April 2016, we executed a restructuring plan to streamline the Company’s operations and product offerings and to align the Company’s expenses with current revenue levels. The plan included an approximately 24% reduction in workforce, primarily in the area of development, however, it also impacted operations, sales and marketing. The plan also included abandonment of certain assets resulting in impairment charges to write off the assets associated with markets we are no longer pursuing. Total restructuring expense included in our statement of operations for the years ended December 31, 2016, 2015 and 2014 is comprised of the following: Year Ended December 31, 2016 2015 2014 Cost of revenue — restructuring: Tooling and inventory write offs $ 1,679 $ — $ — Employee severance and benefits 105 — — 1,784 — — Operating expenses — restructuring: Employee severance and benefits $ 2,513 $ — $ — Licensed technology and other asset write offs 65 — — Other 30 — — 2,608 — — Total restructuring expense $ 4,392 $ — $ — The following is a rollforward of the accrued liabilities related to restructuring for the year ended December 31, 2016: Balance as of December 31, 2015 Expensed Payments Balance as of December 31, 2016 Employee severance and benefits $ — $ 2,618 $ (2,558 ) $ 60 Other — 30 (30 ) — Accrued costs related to restructuring $ — $ 2,648 $ (2,588 ) $ 60 |

Significant components of our deferred tax assets and liabilities are as follows: December 31, 2016 2015 Deferred tax assets: Net operating loss carryforwards $ 77,357 $ 73,903 Research and experimentation credit carryforwards 11,849 11,688 Foreign tax credit carryforwards 3,575 3,884 Deferred stock-based compensation 1,705 2,623 Depreciation and amortization 1,241 1,800 Reserves and accrued expenses 623 606 Capital loss carryforwards — 358 Other 438 490 Total gross deferred tax assets 96,788 95,352 Deferred tax liabilities: Foreign earnings (327 ) (376 ) Other (269 ) (317 ) Total gross deferred tax liabilities (596 ) (693 ) Less valuation allowance (96,079 ) (94,524 ) Net deferred tax assets $ 113 $ 135 With the adoption of Accounting Standards Update No. 2015-17 in the fourth quarter of 2015, we were required to classify all deferred tax assets and liabilities, and any related valuation allowance, as non-current on the balance sheet. We elected to prospectively adopt the accounting standard in the beginning of our fourth quarter of 2015 and prior periods in the consolidated balance sheets were not retrospectively adjusted. Therefore, we have not classified any portion of our net deferred tax asset balance as current as of December 31, 2016 and 2015. The non-current portion of the net deferred tax asset balance was $113 and $135 as of December 31, 2016 and 2015, respectively, and is included in other assets, net in our consolidated balance sheets. ASU 2016-09 is effective for the Company on January 1, 2017. Due to the full valuation allowance on the U.S. net deferred tax assets, we do not expect the adoption of this update to impact our financial position, results of operations, or cash flows. We continue to record a full valuation allowance against our U.S. net deferred tax assets as of December 31, 2016 and 2015 as it is not more likely than not that we will realize a benefit from these assets in a future period. We have not provided a valuation allowance against any of our foreign net deferred tax assets as we have concluded it is more likely than not that we will realize a benefit from these assets in a future period because our subsidiaries in these jurisdictions are cost-plus taxpayers. The net valuation allowance increased $1,555 , increased $1,732 and increased $3,656 for the years ended December 31, 2016, 2015, and 2014, respectively. As of December 31, 2016, we had federal and state net operating loss carryforwards of $225,989 and $11,490 respectively, which will expire between 2017 and 2036. As of December 31, 2016, we had available federal and state research and experimentation tax credit carryforwards of $8,555 and $3,821 , respectively, which will begin expiring in 2019. We have a general foreign tax credit of $2,895 which will begin expiring in 2017. Our ability to utilize our federal net operating losses may be limited by Section 382 of the Internal Revenue Code of 1986, as amended, which imposes an annual limit on the ability of a corporation that undergoes an "ownership change" to use its net operating loss carryforwards to reduce its tax liability. An ownership change is generally defined as a greater than 50% increase in equity ownership by 5% shareholders in any three-year period. We had undistributed earnings of foreign subsidiaries of $2,856 as of December 31, 2016, for which we have recorded a deferred tax liability. Our Chinese subsidiary is designated as an Advanced Technology Service Enterprise, allowing it to benefit from a Chinese tax holiday resulting in a reduction of its tax rate to 15% through 2018 . On December 18, 2015, the Protecting Americans From Tax Hikes Act of 2015 was enacted, which permanently extended the research and development tax credit retroactively, beginning on January 1, 2015. Uncertain Tax Positions We have recorded tax reserves to address potential exposures involving positions that could be challenged by taxing authorities. As of December 31, 2016 the amount of our uncertain tax positions was a liability of $1,419 and a reduction to deferred tax assets of $560 . As of December 31, 2015, the amount of our uncertain tax positions was a liability of $1,519 and a reduction to deferred tax assets of $473 . The following is a summary of the change in our liability for uncertain tax positions and interest and penalties: 2016 2015 Uncertain tax positions: Balance at beginning of year $ 1,863 $ 1,646 Accrual for positions taken in a prior year (126 ) 135 Accrual for positions taken in current year 257 299 Reversals due to lapse of statute of limitations (108 ) (217 ) Balance at end of year $ 1,886 $ 1,863 Interest and penalties: Balance at beginning of year $ 129 $ 226 Accrual for positions taken in prior year 7 9 Accrual for positions taken in current year 19 — Reversals due to lapse of statute of limitations (62 ) (106 ) Balance at end of year $ 93 $ 129 During the years ended December 31, 2016, 2015 and 2014, we recognized $26 , $9 and $17 , respectively, of interest and penalties in income tax expense in our consolidated statements of operations. We file income tax returns in the U.S. and various foreign jurisdictions. A number of years may elapse before an uncertain tax position is resolved by settlement or statute of limitations. Settlement of any particular position could require the use of cash. If the uncertain tax positions we have accrued for are sustained by the taxing authorities in our favor, the reduction of the liability will reduce our effective tax rate. We reasonably expect reductions in the liability for unrecognized tax benefits and interest and penalties of approximately $191 within the next twelve months due to the expiration of statutes of limitation in foreign jurisdictions. We are no longer subject to U.S. federal, state, and foreign examinations for years before 2013, 2012 and 2009, respectively. Our net operating loss and tax credit carryforwards from all years may be subject to adjustment for three years following the year in which utilized. We do not anticipate that any potential tax adjustments will have a significant impact on our financial position or results of operations. We were not subject to, nor have we received any notice of, income tax examinations in any jurisdiction as of December 31, 2016. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES Royalties We license technology from third parties and have agreed to pay certain suppliers a royalty based on the number of chips sold or manufactured, the net sales price of the chips containing the licensed technology or a fixed non-cancelable fee. Royalty expense is recognized based on our estimated average unit cost for royalty contracts with non-cancelable prepayments and the stated contractual per unit rate for all other agreements. Royalty expense was $722 , $826 and $977 for the years ended December 31, 2016, 2015 and 2014, respectively, which is included in cost of revenue in our consolidated statements of operations. 401(k) Plan We sponsor a 401(k) plan for eligible employees. Participants may defer a percentage of their annual compensation on a pre-tax basis, not to exceed the dollar limit that is set by law. A discretionary matching contribution by the Company is allowed and is equal to a uniform percentage of the amount of salary reduction elected to be deferred, which percentage will be determined each year by the Company. We made no contributions to the 401(k) plan during the years ended December 31, 2016, 2015 or 2014. Leases We acquire rights to use certain software engineer design tools under software licenses, accounting for such arrangements is similar to capital leases. Our various office space and equipment leases are classified as operating leases. Certain of our leases for office space contain provisions under which monthly rent escalates over time and certain leases also contain provisions for reimbursement of a specified amount of leasehold improvements. When lease agreements contain escalating rent clauses, we recognize rent expense on a straight-line basis over the term of the lease. When lease agreements provide allowances for leasehold improvements, we capitalize the leasehold improvement assets and amortize them on a straight-line basis over the lesser of the lease term or the estimated useful life of the asset, and reduce rent expense on a straight-line basis over the term of the lease by the amount of the asset capitalized. When lease agreements provide rent holidays, we reduce rent expense on a straight-line basis over the term of the lease by the amount of the rent holiday. As of December 31, 2016, future minimum payments under non-cancelable software licenses and operating lease agreements are as follows: Year Ending December 31, Software licenses Operating leases Total 2017 $ 418 $ 2,329 $ 2,747 2018 — 1,732 1,732 2019 — 914 914 2020 — 192 192 418 $ 5,167 $ 5,585 Less: Interest component (29 ) Present value of minimum software license payments 389 Less: Current portion (389 ) Long-term portion of obligations $ — Rent expense for the years ended December 31, 2016, 2015 and 2014 was $1,770 , $1,735 and $1,740 , respectively. Contract Manufacturers In the normal course of business, we commit to purchase products from our contract manufacturers to be delivered within the next 90 days. In certain situations, should we cancel an order, we could be required to pay cancellation fees. Such obligations could impact our immediate results of operations but would not materially affect our business. Indemnifications Certain of our agreements include limited indemnification provisions for claims from third-parties relating to our intellectual property. It is not possible for us to predict the maximum potential amount of future payments or indemnification costs under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. We have not made any payments under these agreements in the past, and as of December 31, 2016, we have not incurred any material liabilities arising from these indemnification obligations. In the future, however, such obligations could immediately impact our results of operations but are not expected to materially affect our business. Legal Proceedings We are subject to legal matters that arise from time to time in the ordinary course of our business. Although we currently believe that resolving such matters, individually or in the aggregate, will not have a material adverse effect on our financial position, our results of operations, or our cash flows, these matters are subject to inherent uncertainties and our view of these matters may change in the future. |

Earnings Per Share | EARNINGS PER SHARE Basic earnings per share amounts are computed based on the weighted average number of common shares outstanding. Diluted weighted average shares outstanding include the weighted average number of common shares outstanding plus potentially dilutive common shares outstanding during the period. The following schedule reconciles the computation of basic and diluted net loss per share (in thousands, except per share data): Year Ended December 31, 2016 2015 2014 Net loss $ (11,107 ) $ (10,570 ) $ (9,960 ) Weighted average shares outstanding - basic and diluted 28,276 25,088 22,766 Net loss per share - basic and diluted $ (0.39 ) $ (0.42 ) $ (0.44 ) The following weighted average shares were excluded from the calculation of diluted net loss per share as their effect would have been anti-dilutive (in thousands): Year Ended December 31, 2016 2015 2014 Employee equity incentive plans 4,982 4,248 4,346 Potentially dilutive common shares from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the stock purchase plan. |

Stockholders' Equity Note [Abstract] | |
Shareholders' Equity | SHAREHOLDERS’ EQUITY Preferred Stock The Company is authorized to issue 50,000,000 shares of preferred stock with a par value of $0.001 per share. The Board of Directors is authorized to fix or alter the rights, preferences, privileges and restrictions granted to, or imposed on, each series of preferred stock. There were no shares of preferred stock issued as of December 31, 2016 and 2015 . Common Stock The Company is authorized to issue 250,000,000 shares of common stock with a par value of $0.001 per share. Shareholders of common stock have unlimited voting rights and are entitled to receive the net assets of the Company upon dissolution, subject to the rights of the preferred shareholders, if any. Equity Offering On August 12, 2015, we completed the sale of 3,737,500 shares of common stock, in an underwritten registered offering at a price to the public of $4.75 per share. Net proceeds to the Company, after deducting underwriting discounts and commissions and other expenses payable by us were approximately $16,356 . Employee Equity Incentive Plans On May 23, 2006, our shareholders approved the adoption of the Pixelworks, Inc. 2006 Stock Incentive Plan (the "2006 Plan"). The 2006 Plan has since been amended on certain occasions, most recently on May 11, 2016 when our shareholders approved an increase to the total number of authorized shares to 10,683,333 shares. The 2006 Plan replaced our previously existing stock incentive plans including our 1997 Stock Incentive Plan, as amended, our 2001 Nonqualified Stock Option Plan, the Equator Technologies, Inc. 1996 Stock Incentive Plan, as amended, and Equator Technologies, Inc. stand-alone option plans (collectively, "Old Stock Incentive Plans"). Upon adoption of the 2006 Plan, no additional options could be issued under the Old Stock Incentive Plans and as of December 31, 2016, there were no longer any outstanding awards previously granted under the Old Stock Incentive Plans. As of December 31, 2016 , 1,055,704 shares were available for grant under the 2006 Plan. Stock Options Options granted must generally be exercised while the individual is an employee. In May 2009, the 2006 Plan was modified to reduce the contractual life of newly issued stock awards from ten to six years. Our new hire vesting schedule provides that each option becomes exercisable at a rate of 25% on the first anniversary date of the grant and 2.083% on the last day of every month thereafter for a total of 36 additional increments. Our merit vesting schedule provides that merit-type awards become exercisable monthly over a period of three years.

The following is a summary of restricted stock activity: Number of shares Weighted average grant date fair value Unvested at December 31, 2015: 918,676 $ 5.62 Granted 1,572,519 2.21 Vested (529,926 ) 4.40 Canceled (262,769 ) 5.04 Unvested at December 31, 2016: 1,698,500 $ 2.93 Expected to vest after December 31, 2016 1,433,081 $ 2.93 Employee Stock Purchase Plans On May 18, 2010, our shareholders approved the adoption of the 2010 Pixelworks, Inc. Employee Stock Purchase Plan (the "ESPP") for U.S. employees and for certain foreign subsidiary employees. The ESPP provides for separate offering periods commencing on February 1 and August 1, with the first offering period beginning August 1, 2010. Each offering period continues for a period of 18 months with purchases every six months . Each eligible employee may purchase up to 3,000 shares of stock on each purchase date, with a maximum annual purchase amount of $25 . The purchase price is equal to 85% of the lesser of the fair market value of the shares on the offering date or on the purchase date. A total of 1,300,000 shares of common stock have been reserved for issuance under the ESPP. During the years ended December 31, 2016 , 2015 and 2014, we issued 141,633 , 92,899 and 101,201 shares, respectively for proceeds of $252 , $352 and $274 , respectively, under the ESPP. Stock-Based Compensation Expense The fair value of stock-based compensation was determined using the Black-Scholes option pricing model and the following weighted average assumptions: Year Ended December 31, 2016 2015 2014 Stock Option Plans: Risk free interest rate 1.37 % 1.52 % 1.64 % Expected dividend yield 0 % 0 % 0 % Expected term (in years) 5.00 5.00 5.00 Volatility 74 % 68 % 73 % Employee Stock Purchase Plan: Risk free interest rate 0.20 % 0.28 % 0.22 % Expected dividend yield 0 % 0 % 0 % Expected term (in years) 1.12 1.10 1.02 Volatility 84 % 89 % 82 % The weighted average fair value of options granted during the years ended December 31, 2016 , 2015 and 2014 was $1.41 , $2.93 and $3.50 , respectively. The risk free interest rate is estimated using an average of treasury bill interest rates. The expected dividend yield is zero as we have not paid any dividends to date and do not expect to pay dividends in the future. Expected volatility is estimated based on the historical volatility of our common stock over the expected term as this represents our best estimate of future volatility. Subsequent to the May 2009 amendment of our 2006 Stock Incentive Plan, which shortened the contractual life of newly issued stock options from ten to six years, we have elected to use the "simplified method" to estimate expected term. Under the simplified method, an option's expected term is calculated as the average of its vesting period and original contractual life. The expected term of ESPP purchase rights is based on the estimated weighted average time to purchase. As of December 31, 2016 , unrecognized stock-based compensation expense is $3,049 , which is expected to be recognized as stock-based compensation expense over a weighted average period of 2.80 years. |

Summary of Significant Accoun21
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2016 | |
Accounting Policies [Abstract] | |
Use of Estimates, Policy | The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires us to make estimates and judgments that affect amounts reported in the financial statements and accompanying notes. Our significant estimates and judgments include those related to revenue recognition, product returns, warranty obligations, bad debts, inventories, property and equipment, impairment of long-lived assets, valuation of share-based payments, income taxes, litigation and other contingencies. The actual results experienced could differ materially from our estimates. |
Cash and Cash Equivalents, Policy | We classify all cash and highly liquid investments with original maturities of three months or less at the date of purchase as cash and cash equivalents. Cash equivalents, which consist of U.S. denominated money market funds totaled $17,960 and $25,343 as of December 31, 2016 and 2015 , respectively. |
Accounts Receivable, Policy | Accounts receivable are recorded at invoiced amount and do not bear interest when recorded or accrue interest when past due. We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. At the end of each reporting period, we estimate the allowance for doubtful accounts based on an account-by-account risk analysis of outstanding receivable balances. The determination to write-off specific accounts receivable balances is made based on the likelihood of collection and past due status. Past due status is based on invoice date and terms specific to each customer. |
Inventories, Policy | Inventories consist of finished goods and work-in-process, and are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value). |
Property and Equipment, Policy | Property and equipment are stated at cost. Depreciation and amortization is calculated on a straight-line basis over the estimated useful life of the assets which are generally as follows: Software Lesser of 3 years or contractual license term Equipment, furniture and fixtures 2 years Tooling 2 to 4 years Leasehold improvements Lesser of lease term or estimated useful life The cost of property and equipment repairs and maintenance is expensed as incurred. |
Licensed Technology, Policy | We have capitalized licensed technology assets in other long-term assets. These assets are stated at cost and are amortized on a straight-line basis over the term of the license or the estimated life of the asset, if the license is not contractually limited, which is generally two to five years. |
Useful Lives and Recoverability of Equipment and Other Long-Lived Assets, Policy | If there is an indicator of impairment, we prepare an estimate of future, undiscounted cash flows expected to result from the use of each asset and its eventual disposition. If these cash flows are less than the carrying value of the asset, we adjust the carrying amount of the asset to its estimated fair value. |
Revenue Recognition, Policy | We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed and determinable, and collection is reasonably assured. For product sales, we require customers to provide purchase orders prior to shipment and we consider delivery to occur upon shipment provided title and risk of loss have passed to the customer based on the shipping terms. These conditions are generally satisfied upon shipment of the underlying product. There are no customer acceptance provisions associated with our products, and except for replacement of defective products under our warranty program discussed below, we have no obligation to accept product returns from end customers; however, we have accepted returns on a case-by-case basis as customer accommodations in the past. As a result, we provide for estimated reductions to gross profit for these sales returns in our reserve for sales returns and allowances. At the end of each reporting period, we estimate the reserve based on historical experience and knowledge of any applicable events or transactions. The reserve is included in accrued liabilities in our consolidated balance sheets. A portion of our sales are made to distributors under agreements that grant the distributor limited stock rotation rights and price protection on in-stock inventory. The stock rotation rights allow these distributors to exchange a limited amount of their in-stock inventory for other Pixelworks product. As a result, we provide for estimated reductions to gross profit for these stock rotations in our reserve for sales returns and allowances. At the end of each reporting period, we estimate the reserve based on historical experience and knowledge of any applicable events or transactions. The reserve is included in accrued liabilities in our consolidated balance sheets. On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Our license fee arrangements generally include multiple deliverables and we are required to determine whether there is more than one unit of accounting. To the extent that the deliverables are separable into multiple units of accounting, we allocate the total fee on such arrangements to the individual units of accounting using management’s best estimate of selling price ("ESP"), if third party evidence ("TPE") or vendor specific objective evidence ("VSOE") does not exist. We defer revenue recognition for consideration that is contingent upon future performance or other contractual terms. The Company's process for determining its ESP for deliverables without VSOE or TPE considers multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. The key factors considered by the Company in developing the ESPs include the nature and complexity of the licensed technologies, our cost to provide the deliverables, the availability of substitute technologies in the marketplace and the Company's historical pricing practices. We then recognize revenue for each unit of accounting depending on the nature of the deliverable(s) comprising the unit of accounting in accordance with the revenue recognition criteria mentioned above. Fees under these agreements generally include (a) license fees relating to our IP, (b) engineering services, and (c) support services. Historically, each of these elements have standalone value and therefore each are treated as separate units of accounting. Any future licensing arrangements will be analyzed based on the specific facts and circumstances which may be different than our historical licensing arrangements. For deliverables related to licenses of our technology that involve significant engineering services, we recognize revenue in accordance with the provisions of the proportional performance method. We determine costs associated with engineering services using actual labor dollars incurred and estimated other direct or incremental costs allocated based on the percentage of time the engineer(s) spent on the project. These costs are deferred until revenue recognition criteria have been met, at which time they are reclassified as cost of revenue. |
Warranty Program, Policy | We warrant that our products will be free from defects in material and workmanship for a period of twelve months from delivery. Warranty repairs are guaranteed for the remainder of the original warranty period. Our warranty is limited to repairing or replacing products, or refunding the purchase price. At the end of each reporting period, we estimate a reserve for warranty returns based on historical experience and knowledge of any applicable events or transactions. The reserve for warranty returns is included in accrued liabilities in our consolidated balance sheets. |
Share-Based Compensation, Policy | We currently sponsor a stock incentive plan that allows for issuance of employee stock options and restricted stock awards, including restricted stock units. We also have an employee stock purchase plan for all eligible employees. The fair value of share-based payment awards is expensed straight-line over the requisite service period, which is generally the vesting period, for the entire award. Additionally, any modification of an award that increases its fair value will require us to recognize additional expense. The fair value of our stock option grants and purchase rights under our employee stock purchase plan are estimated as of the grant date using the Black-Scholes option pricing model which is affected by our estimates of the risk free interest rate, our expected dividend yield, expected term and the expected share price volatility of our common shares over the expected term. The fair value of our restricted stock awards are based on the market value of our stock on the date of grant, adjusted for the effect of estimated forfeitures. |
Research and Development, Policy | Costs associated with research and development activities are expensed as incurred, except for items with alternate future uses which are capitalized and depreciated over their estimated useful lives. On occasion, we enter into co-development arrangements with current or prospective integrated circuit ("IC") customers to defray a portion of the research and development expenses we expect to incur in connection with our development of an IC product. As amounts become due and payable without recourse under co-development agreements, they are offset against research and development expense up to the amount of related costs incurred. |
Income Taxes, Policy | We account for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We establish a valuation allowance to reduce deferred tax assets if it is "more likely than not" that a portion or all of the asset will not be realized in future tax returns. An uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. Until these positions are sustained by the taxing authorities, we do not recognize the tax benefits resulting from such positions and report the tax effects for uncertain tax positions in our consolidated balance sheets. |
Fair Value of Financial Instruments, Policy | Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Three levels of inputs may be used to measure fair value: Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities. Level 2: Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Valuations based on unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions. |
