A CMOS imager with new focal-plane motion detectors has been developed as the front-end of vision systems. The chip generates both a normal video signal and a local image signal; i.e. the local area where the motion is detected is automatically scanned. Key technologies include a unity-gain two-port pixel, sparsely-placed motion detectors, and a multistage column readout circuit. A 5.8/spl times/8.7 mm/sup 2/ chip fabricated by using 0.35 /spl mu/m CMOS process contains 192/spl times/192 pixels and 7/spl times/7 motion detectors.
