A 128 × 128 pixel 120-dB dynamic-range vision-sensor chip for image contrast and orientation extraction.

A vision sensor for low-cost, fast, and robust vision systems is described. The sensor includes an on-chip analog computation of contrast magnitude and direction of image features. A temporal ordering of this information according to the contrast magnitude is used to reduce the amount of data delive...
