ZORAN CORPORATION ANNOUNCES PRELIMINARY RESULTS FOR THE THIRD QUARTER 2004

SUNNYVALE, Calif.  (October 5, 2004)  — Zoran Corporation (Nasdaq NM: ZRAN), a leading provider of digital solutions-on-a-chip for applications in the growing digital entertainment and digital imaging markets, today announced preliminary results for its third quarter ended September 30, 2004.

Revenues for the third quarter are expected to range between $115 million and $119 million, compared with previous guidance of $128 million to $133 million.  This represents an 11 to 15 percent increase over the second quarter of 2004 and a 61 to 67 percent increase over the same quarter of last year.  Third quarter earnings per share are anticipated to decrease by approximately $0.11 to $0.14 from previously guided pro forma levels.

The Company attributes the lower than anticipated results for the third quarter to an inventory correction occurring in the Chinese manufactured DVD Player market causing some of the Company’s customers to delay orders as they work to deplete their excess inventory.  In addition, there seems to be significant tightening of credit lines within China, which is contributing to more conservative manufacturing commitments and shorter term outlooks. As a result of these factors, the Company did not experience the seasonally high turns-business normally seen toward the end of the third quarter.

“While we are obviously disappointed with the lower than expected revenues for the third quarter, we are continuing to grow our businesses at substantial rates during these challenging market conditions,” said Levy Gerzberg, the Company’s President and Chief Executive Officer.  “In addition, Zoran continues to be one of the largest suppliers to the DVD market, and we maintained the market share gains we achieved during the first half of the year.  Our positions in

our other businesses; Multifunction Printers, DTV, and Digital Cameras remain strong, and we continue to build our position in our new Mobile phone market segment.”

The Company will release its third quarter results after market on October 26, 2004 and provide additional commentary and information at that time.
