ABSTRACT:
A signal processor is disclosed for operating on signals provided by a photodetector, particularly photodetectors, or arrays thereof, for use in image processing. The processor is particularly well implemented by use of charge-coupled device technology for sampling and processing the photodetector signals. The photodetector signals are sampled many times in a frame to provide a combined result representation of an image element in that frame to thereby reduce noise associated therewith.
