                     CELLULAR CAMERA PHONE REVENUES TRIPLES

     FREMONT, CALIF., FEBRUARY 4, 2004--ESS Technology (Nasdaq: ESST) today
reported net revenues for the fourth quarter of 2003 of $82.9 million, a 75%
increase over the same period last year of $47.5 million and a 72% sequential
increase from the $48.2 million reported for the third quarter of 2003.

     GAAP net income for the fourth quarter of 2003 was $8.8 million, or $0.21
per diluted share, compared to GAAP net income of $0.8 million, or $0.02 per
diluted share, for the fourth quarter of 2002. For the third quarter of 2003,
GAAP net income was $2.7 million, or $0.07 per diluted share.

     Non-GAAP net income for the fourth quarter of 2003 was $9.5 million, or

of $1.4 million, or $0.03 per diluted share. For the third quarter of 2003,
Non-GAAP net income was $5.3 million or $0.13 per diluted share. Non-GAAP net
income excludes the effects of amortization of intangible assets, write-down of
investments, investment gains, in-process research and development, and their
related tax effects.

     Robert Blair, president and CEO of ESS Technology commented, "I am very
pleased to report that new products and recent acquisitions are driving
significant revenue and earnings growth. Our Vibratto II integrated chips and
our VibrattoS MPEG4/DivX chips led our strong DVD gains, and our VCD products
again set new sales records as the VCD market continues its growth worldwide.
And during the fourth quarter our recordable DVD products continued their rapid
growth and set a new revenue record. All of our digital video product lines grew
during the fourth quarter, and additionally and most importantly, growth in

                                       1


our new cameraphone business is exceeding our earlier expectations, with revenue
more than triple that of the third quarter."

     Mr. Blair continued, "We are extremely excited by the rapid growth of our
CMOS image sensor revenue, the rapid expansion of the cameraphone market, and
the huge opportunity this represents for ESS. Industry forecasts for the growth
of cameraphones continue to rise, with recent industry forecasts as high as
150-250 million units in 2004. We recognize this great opportunity for ESS and
we plan to become a major player in this market. We are expanding our resources
in engineering, operations, sales and marketing to win and support more business
in this fast-growing market."

     Mr. Blair concluded, "Overall, with the strength and growth of both the
digital imaging and digital video markets and our many new products for these
markets, ESS is looking forward to significant growth in the future."

     Jim Boyd, CFO of ESS Technology commented, "ESS in the fourth quarter
achieved our strongest growth ever, with sequential revenue growth in all
segments of our business. Digital imaging revenue more than tripled and
sequential earnings per share also tripled. In addition, we ended the year with
approximately $165 million in cash and short-term investments and zero debt.
Overall, we are very pleased with ESS's results and financial position at the
end of 2003."

(1) Use of Non-GAAP Financial Information:

To supplement our consolidated financial statements presented in accordance with
GAAP, we use non-GAAP measures of operating results, net income/(loss) and
earnings per share, which are adjusted from results based on GAAP to exclude
certain expenses, gains and losses. These non-GAAP measures are provided to
enhance the user's overall understanding of our current financial performance
and our prospects for the future. Specifically, we believe the non-GAAP results
provide useful information to both management and investors by excluding certain
expenses, gains and losses that we believe are not indicative of our on-going
core operating results. In addition, since we have historically reported
non-GAAP results to the investment community, we believe the inclusion of
non-GAAP numbers provides consistency in our financial reporting. Further, these
non-GAAP results

                                       6


are one of the primary indicators management uses for planning and forecasting
results for future periods. The non-GAAP information is presented using
consistent methodology from quarter-to-quarter and year-to-year. These measures
should be considered in addition to results prepared in accordance with GAAP,
but should not be considered a substitute for or superior to GAAP results.

(2) Non-GAAP adjustments are detailed within the schedule entitled
"Reconciliation of GAAP Net Income to Non-GAAP Net Income".
