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.

Vision sensor, event signal processing method of the vision sensor, and imaging processing device including the vision sensor

Provided are a vision sensor and an image processing device including the vision sensor. The vision sensor includes a pixel array including a plurality of pixels each including a photoelectric conversion device, which is configured to generate an optical current, a read-out circuit configured to generate intensity image data based on a magnitude of a voltage converted from the optical current, and a data output logic configured to generate event data based on a variation amount in the voltage converted from the optical current.

Vision sensor and image processing device including the same

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.
