Design and Implementation of Adaptive-integration-time Image Sensor

Abstract

We describe a new adaiptive-integration-time image sensor based on a column parallel architecture which has 128×64 pixels. In this prototype. the scheme to control integration time is greatly extended, and the pixel pitch, processing speed, and power consumption are improved compared with our previous version. Both the in time and output timing are decided the combination of three elements : motion detection, saturation detection. and external signal control. We have fabricated the prototype using the CMOS 0.8 μm process and show the results or some experiments.
