Exhibit 99.1

OMNIVISION RECONFIRMS JULY 23 FOR SPECIAL MEETING OF SHAREHOLDERS

SANTA CLARA, Calif., — July 17, 2015 — OmniVision Technologies, Inc. (Nasdaq: OVTI) (“OmniVision”), a leading developer of advanced digital imaging solutions, today reconfirmed that the special meeting of OmniVision stockholders will be held on July 23, 2015.

As previously disclosed, OmniVision is a party to a number of putative class action lawsuits related to the merger of Seagull Acquisition Corporation with and into OmniVision (the “Merger”) pursuant to the Agreement and Plan of Merger, dated April 30, 2015, by and among OmniVision, Seagull International Limited and Seagull Acquisition Corporation (as may be amended from time to time) that have been filed in the Superior Court of the State of California, County of Santa Clara. Those actions were consolidated under the caption In re OmniVision Technologies, Inc. Shareholder Litigation, No. 15-CV-280161 (the “Litigation”) and are described in more detail in the Proxy Statement filed June 10, 2015 with the Securities and Exchange Commission. On July 1, 2015, plaintiffs filed a motion seeking to enjoin the Merger until the defendants in the Litigation take certain purported corrective actions. Thereafter, OmniVision voluntarily postponed the previously announced special meeting of OmniVision stockholders in order to provide additional time for court resolution of that motion. On July 16, 2015, the Court held a hearing on that motion. At the conclusion of the hearing, the Court denied, in its entirety, plaintiffs’ motion seeking to enjoin the Merger. As previously announced, the special meeting will be held on July 23, 2015.
