A PC camera multimedia processor is an image processing semiconductor embedded in a PC camera. It receives image signals from the camera sensor and processes and transmits the signals in digital format to the PC to which the camera is attached. Our PC camera multimedia processors are fully compatible with sensors that are based on CMOS or CCD technology, the two primary types of technology for sensors.

We design different models of PC camera multimedia processors based on the same core technology
platform with modifications in successive models with improved performance and functionality. All of our PC camera multimedia processors are single-chip processors manufactured under our own brand name using our proprietary intellectual property. While our principal focus is on providing our customers with proprietary, high performance products, we also develop and sell a range of basic, complementary semiconductor products in order to provide more comprehensive solutions for our customers.

The following table sets forth the major PC camera multimedia processors which we have developed and shipped in volume.
