Abstract
A vision sensor includes a memory; a pixel array including a plurality of pixels configured to generate an event signal by detecting an event in which an intensity of incident light changes; and an event detection circuit configured to read the event signal from the pixel array and configured to process the event signal, wherein the event detection circuit configured to: store, in the memory, a state map including a first state corresponding to a presence of an event of each of the plurality of pixels, and a second state corresponding to an absence of the event, and correct the event occurring in a selected pixel, based on the state map stored in the memory.
