A CMOS High-Speed Non-Destructive Intermediate Image Sensor

Abstract

A CMOS image sensor has been developed. The sensor captures non-destructive intermediate pictures and fully accumulated video-rate pictures. It is useful for applications that require both high-speed pictures and fully accumulated video-rate pictures, such as motion-vector estimation for moving-picture encoding and motion tracking cameras. The sensor uses bi-directional multiple charge transfer active pixels and is fabricated using 0.35 μm CMOS technology. It captures 480 frame/s high-speed intermediate pictures and 30 frame/s fully accumulated video-rate pictures with FPN reduction in both type of pictures.
