GENERAL DESCRIPTION

The SAA8112HL is a powerful and versatile 10-bit digital processor for video cameras. It processes the digitized sensor data and converts it to a high quality, multi-format and YUV digital signal. In addition, the SAA8112HL performs programmable statistical measurements on the video stream allowing, for instance, a precise measurement of the exposure or the white balance levels.
