Abstract: Provided is an image sensor. The image sensor including a plurality of pixels, and processing circuitry configured to, generate first image data by converting optical signals received by each of the plurality of pixels during a first exposure time into electrical signals, generate event data including information related to a change in intensity of the optical signals received by each of the plurality of pixels during the first exposure time, the event data having a frame rate greater than a frame rate of the first image data, receive the first image data and the event data, and generate output data by sequentially packing the first image data and the event data corresponding to the first exposure time.

Abstract: A vision sensor is provided. The vision sensor includes: a pixel array including a plurality of pixels, each of the plurality of pixels being configured to generate an event signal based on an event in which intensity of incident light changes; and an event detection circuit including a state register including a first flip-flop and a second flip-flop. The event detection circuit is configured to: based on the event signal, store first data in the first flip-flop, the first data indicating whether flicker has occurred in each of the plurality of pixels, store second data in the second flip-flop, the second data indicating whether the event has occurred in each of the plurality of pixels, and based on a comparison of the first data and the second data, identify and delete a portion of the second data in which the flicker has occurred.
