Abstract
Provided is a vision sensor including a pixel array including a plurality of pixels disposed in a matrix form, an event detection circuit configured to detect whether an event has occurred in the plurality of pixels and generate event signals corresponding to pixels from among the plurality of pixels in which an event has occurred, a map data processor configured to generate a timestamp map based on the event signals, and an interface circuit configured to transmit vision sensor data including at least one of the event signals and the timestamp map to an external processor, wherein the timestamp map includes timestamp information indicating polarity information, address information, and an event occurrence time of a pixel included in an event signal corresponding to the pixel.
