... Typical application 1.2.1 USB webcam This sensor may be used in conjunction with the STMicroelectronics STV0676 co-processor to produce a low cost USB webcam. In this application the co-processor supplies the sensor clock and uses the embedded control sequences to synchronise with the frame and line level timings. It then performs the colour processing on the raw image data from the sensor before supplying the final image data to the host using the USB interface ...
