128×128 pixels image compression sensor

Abstract

We propose a novel image sensor which compresses image signal on the sensor plane. By the integration of sensing and compression, number of pixels in the image signal that has to be readout from the sensor can be significantly reduced. In this paper, we describe a new prototype sensor based on a column parallel architecture which has 128x128 pixels. We have revised the processing circuits of the new prototype to achieve much lower power dissipation and higher processing speed.
