Real-time image processing by using image compression sensor
We have been investigating an integration of sensing and compression on an image sensor. The compression sensor reduces the number of pixels in the image signal that has to be readout from the sensor. Therefore, the compression sensor can capture the images at the higher pixel rate which the traditional sensor can not handle. In this paper, we present a compression sensor which has 228/spl times/128 pixels. The processing circuits of the sensor can be operated at 5000 frames/second. We also describe the experimental results of two real-time image processing systems by using the compression sensor. They are a reconstruction circuit by using FPGA and a stereo image processing system for tracking of a moving object.
