Abstract
We have been investigating the adaptive-integration-time image sensor. In this paper, we describe a new adaptive-integration-time image sensor based on a column parallel architechture which has 128×64 pixels. In this new prototype, the scheme to control integration time is much extended, and pixel pitch, processing speed and power consumption are much improved in comparison with our previous prototype. It has the circuits for detection of saturation and motion. Both integration time and output timing of the pixel value are controlled by any combination of three elements, which are motion detection, saturation detection and external signal. We have fabricated a prototype using CMOS 0.8μm process and show results of some experiments.
