Abstract
An event-based sensor includes a photoarray and a processing circuit. The photoarray includes an array of cells. Each cell includes a photosensor generating a sensor signal dependent on an intensity of light casted on the cell, and an intensity monitoring circuit outputting an ON signal when the light intensity is increasing and an OFF signal when the light intensity is decreasing. The processing circuit is configured to generate an event in response to the ON and OFF signals, filter out the events caused by flickering light, and pass the events caused by motion.
