1. A vision sensor, comprising:
a pixel array including a plurality of pixels arranged in a matrix, each pixel of the plurality of pixels configured to generate a separate electrical signal in response to detecting a change in intensity of incident light;
an event detection circuit configured to process electrical signals received from the plurality of pixels, and generate event signals corresponding to the plurality of pixels, at which the change in intensity of the incident light is determined to have occurred, respectively; and
an event rate controller configured to adjust an event detection period based on an amount of event signals.
