Event-based sensor, user device including the same, and operation method of the same
An event-based sensor includes a dummy pixel that generates a dark current, a current mirror that generates a mirrored current using the dark current, and a sensing pixel that generates a sense current based on an intensity of incident light, and outputs an activation signal, indicating whether a variation in the incident light is sensed, based on a light current that is obtained by subtracting the mirrored current from the sense current.
