1. An electronic device comprising:
a dynamic vision sensor including a first pixel configured to sense a change in light intensity, and configured to generate an event signal based on the sensed change in the light intensity;
an illuminance estimator configured to estimate illuminance of a light; and
a time delay compensator configured to calculate a time delay between a first time at which the change in the light intensity occurs and a second time at which the first pixel senses the change in the light intensity, based on the illuminance of the light, and to compensate for the time delay.
