Abstract
A vision sensor responds to temporal contrast with asynchronous output. Each pixel independently and continuously quantizes changes in log intensity. The 128X128-pixel chip has 120dB illumination operating range and consumes 30mW. Pixels respond in <100mus at 1klux scene illumination with <10% contrast-threshold FPN
