FULLY INTEGRATED SOLID STATE IMAGER AND CAMERA CIRCUITRY

摘要

There is shown an single chip CMOS device (100) for capturing a video image. The device includes an APS imager (110) containing an array of pixels for providing a signal representing a scene, a row of extended dynamic range sample and hold circuits (111) for receiving a signal from the array of pixels and a row of linear sample and hold circuits (112) for receiving another signal for said array of pixels. Also included is an image processor (120) for determining a controllable function and for processing a plurality of signals received from the extended dynamic range sample and hold circuits and the linear sample and hold circuits according to said controllable function to form a processed video signal. Further included is a memory (130) for storing the controllable function and the processed video signal.
