Compact Integrated Motion Sensor With Three-Pixel Interaction
April 1996 (vol. 18 no. 4)
pp. 455-460

Abstract—An integrated circuit with on-chip photoreceptors is described, that computes the bi-directional velocity of a visual stimulus moving along a given axis in the focal plane by measuring the time delay of its detection at two positions. Due to the compactness of the circuit, a dense array of such motion-sensing elements can be monolithically integrated to estimate the velocity field of an image and to extract higher-level image features through local or global interaction.
