In order to enhance the performance of image sensing, we have been investigating a novel integration of sensing and compression on an image sensor. By the integration, the number of pixels in the image signal that has to be readout from the sensor can be significantly reduced, and the integration can consequently increase the pixel rate. In this paper, we describe a new compression sensor based on a column parallel architecture. We have implemented the prototype which has 128/spl times/128 pixels. It is verified that the processing circuits of the prototype can operate at more than 5000 frames/second. We also show the results of two experiments which are real-time reconstruction and real-time tracking and depth estimation of a moving object.
