          OMNIVISION TECHNOLOGIES, INC. ADOPTS STOCKHOLDER RIGHTS PLAN

SUNNYVALE, Calif., August 23, 2001 -- OmniVision Technologies, Inc. (Nasdaq:
OVTI) today announced that its board of directors has adopted a Stockholder
Rights Plan. Under the plan, OmniVision Technologies, Inc. will issue a dividend
of one right for each share of common stock, par value of $0.001 per share, of
the company held by stockholders of record as of the close of business on
September 28, 2001. The plan is designed to assure stockholders fair value in
the event of a future unsolicited business combination or similar transaction
involving the company. The Company added that the plan was not adopted in
response to any attempt to acquire the company, and that it is not aware of any
such efforts.

Each right will initially entitle stockholders to purchase a fractional share of
the company's preferred stock for $40.00. However, the rights are not
immediately exercisable and will become exercisable only upon the occurrence of
certain events. Upon certain other events, unless redeemed for $0.001 per right,
the rights will become exercisable by holders, other than rights held by an
unsolicited third party acquirer, for shares of the company or of the third
party acquirer having a value of twice the right's then-current exercise price.
Further details of the plan are outlined in a letter that will be mailed to
stockholders as of the record date.
