Abstract

Novel use of an analog motion detection circuit is presented. The circuit, developed by Tanner and Mead, computes motion by dividing the time derivative of intensity by its spatial derivative; the four-quadrant division is realized with a multiplier within a negative feedback loop. The authors have opened the loop and characterized the circuit as a multiplication-based motion detector, in which the output is the product of the temporal and spatial derivatives of intensity, for various light levels and various moving patterns. An application to the time-to- contact computation is presented.
