Abstract
Provided are a vision sensor, an image processing device including the vision sensor, and an operating method of the vision sensor. The vision sensor includes a plurality of pixels arranged in a matrix form, wherein each of the plurality of pixels includes: a sensing circuit configured to output an output voltage by sensing a change of light; a comparison circuit configured to output a comparison signal indicating whether an event has occurred by comparing the output voltage to an event threshold; and an event detection circuit configured to generate internal event signals by sampling the comparison signal at each of a plurality of sampling time points, and configured to output a valid event signal based on the internal event signals.
