1. A vision sensor, comprising:
a pixel array comprising a plurality of pixels arranged in a matrix, each pixel of the plurality of pixels configured to generate one or more electrical signals in response to a change in intensity of incident light;
an event detection circuit configured to process one or more 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; and
an event rate controller configured to adjust an event detection threshold value based on illuminance information associated with an object or an external region including the object.
