Shanghai, China – November 18, 2004 – At a press conference held in Shanghai on Thursday, November 18, OmniVision Technologies (Nasdaq: OVTI), a leading global supplier of CMOS image sensors for digital imaging solutions, demonstrated a prototype of its OV810 Smart Sensor™, an image sensor that is capable of storing and subsequently identifying unique images for applications such as character recognition and facial recognition.

The OV810 Smart Sensor incorporates a classifier called a support vector machine (SVM), a device that provides ultra-fast computing power for technology requiring pattern recognition and information classification. Because they learn by example, devices incorporating SVM techniques require little knowledge on the part of the device. Unlike conventional computing techniques, which handle problems through mathematical models and algorithms, they are trained, not programmed. The first expected enduser application for the OV810 is in smart toys.

OmniVision expects to have samples of the OV810 Smart Sensor available in the first half of 2005.
