Abstract :
We have been investigating a novel integration of sensing and compression on an image sensor. By 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 of the sensor. We present a new compression sensor which has 128×128 pixels. We have made the prototype based on a column parallel architecture and improved the processing circuits of the new prototype to achieve lower power dissipation and higher processing speed in comparison with our previous prototypes. It is verified that the processing circuits can be operated at 5000 frames/second
