Abstract
This paper describes a CMOS image sensor with non-destructive high-speed imaging mode. The proposed sensor reads out high-speed intermediate images without destroying accumulated signal charge and captures video-rate (30 frame/s) images with high SNR. The application of the sensor to a low power motion vector estimation for video compression and high-fidelity imaging of moving object with tracking are also presented. Motion vector estimation using the proposed sensor is possible to reduce computational power by a factor of 1/10 compared to the full search algorithm. The simulation results show that the proposed image sensor with nondestructive high-speed imaging mode is useful for moving object imaging with less shape distortion.
