摘要：We propose a novel image sensor which compresses image data on its sensor plane. The image compression sensor can significantly reduce the amount of pixel data output from the sensor. The proposed sensor is intended to overcome the communication bottleneck in high-pixel-rate imaging, such as high-frame-rate and high-resolution imaging. The compression algorithm is based on conditional replenishment. It detects motion and encodes only the pixels in moving areas. This paper describes the design and implementation of the proposed sensor based on column parallel architecture. In this architecture, fill factor and power dissipation are at a similar level to those of conventional MOS sensors. We show the results of some experiments using a prototype chip.
