A Smart CMOS Imager with On-Chip High Speed Windowed Controiding Capability

Low-power, high-speed, accurate computation of centroid from a pre-defined window in the image plane is important for a number of space-based and commercial applications. These include object tracking in robotic systems [l], autonomous navigation, image compression [2], and document copyright protection [3], as well as space guidance and navigation systems [4], and deep-space optical communication systems that require accurate and stable beam pointing for high speed data transfer 151.
