	Form 8-K dated January 25, 2005

Dear Ms. Gohlke:

     Reference is made to the letter, dated May 24, 2005, of the staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) addressed to Silicon Image, Inc. (the “Company”), regarding the above-referenced filings. Provided below are responses to each of the numbered comments of the Staff. Please note that the headings and numbers of the responses set forth below correspond to the headings and numbers of the comments contained in the letter of the Staff.

Form 8-K dated April 21, 2005

1. We note that your response to our prior comment 5 and see that you have deleted the pro forma statement of operations. However, we note you continue to include a discussion of pro forma net income and pro forma net income per share. Since you have retained certain non-GAAP measures you must provide statements disclosing the reasons why management believes presentation of each of the individual non-GAAP measures provide useful information to investors regarding your financial condition and results of operations. Those disclosures should bespecific andsubstantative to each measure. Revise your Forms 8-K in future periods to provide all of the disclosures required by Item 10(e)(1)(i) for each non-GAAP measure presented. See also Question 8 of the FAQ Regarding the Use of Non-GAAP Financial Measures, dated June 13, 2003. Please provide us with a full sample of your proposed disclosure.

     We have supplementally attached, for the Staff’s review, a sample template of the Company’s proposed disclosure to be used as a basis for its press release announcing the Company’s financial results for the quarter ended June 30, 2005, which will be furnished to the

Securities and Exchange Commission
July 28, 2005
Page 2

SEC as an exhibit to a Form 8-K. Please note that this sample template includes non-GAAP supplemental financial information, and includes additional specific and substantive disclosure related to non-GAAP net income and net income per share, and to each non-GAAP measure included in the non-GAAP supplemental financial information in compliance with Item 10(e)(1)(i). These disclosures are set forth in both (1) the notes following the table under the caption “Reconciliation of GAAP to Non-GAAP Net Income” and (2) the notes following the table under the caption “Non-GAAP Supplemental Financial Information.”

2. Further, we note that you refer to your non-GAAP information as “pro forma” results. The pro forma terminology has very specific meaning in accounting literature, as indicated by Article 11 of Regulation S-X. Please revise your presentation in future filings to omit the pro forma terminology when referring to your non-GAAP information.

     The sample earnings press release template attached hereto eliminates the term “pro forma” when referring to non-GAAP information. Additionally, the Company will revise its presentation in future filings to omit the term “pro forma” when referring to non-GAAP information.

     Should the Staff have additional questions or comments regarding the foregoing, please do not hesitate to contact the undersigned at (415) 875-2455.

Very truly yours,

/s/ David K. Michaels

SILICON IMAGE REPORTS [SECOND QUARTER 2005] FINANCIAL RESULTS

[Language describing quarterly financial results]

* Note Regarding Non-GAAP Financial Information
The non-GAAP financial information set forth in this press release is presented for informational purposes only. Our presentation of non-GAAP financial information excludes stock compensation expense and amortization of intangible assets. It also excludes patent assertion costs and gains (losses) on equity investments, which are not directly attributable to our ongoing operations and are expected to be non-recurring or to be incurred over a limited period of time. We believe that the exclusion of these items can help investors better understand our underlying operating performance. Additionally, items such as these mentioned above have the potential to distort our ability to provide a meaningful comparison of financial results across reporting periods. For these reasons, management does not evaluate these items when assessing the performance of our ongoing operations or when allocating resources.

These gains or losses are infrequent and unusual, and reflect market and other conditions that are unrelated to our ongoing business operations.
