An Integrated Analog Optical Motion Sensor
John E. Tanner, Carver Mead · CaltechAUTHORS (California Institute of Technology) · 1986
This paper describes the theory and implementation of an integrated system that reports the uniform motion of a visual scene. We have built a VLSI circuit that reports the motion of an image focused directly on it. The chip contains an integrated photosensor array to sense the image and has closely coupled custom circuits to perform computation and data extraction.
