摘要

开发了一种具有新型焦平面运动检测器的CMOS成像仪，作为视觉系统的前端。该芯片产生一个正常的视频信号和一个本地图像信号;即自动扫描检测到运动的局部区域。关键技术包括单位增益双端口像素，稀疏放置的运动检测器和多级列读出电路。采用0.35 /spl mu/m CMOS工艺制作的5.8/spl倍/8.7 mm/sup /芯片包含192/spl倍/192像素和7/spl倍/7个运动检测器。

A CMOS imager with new focal-plane motion detectors

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.
