Abstract
An event can be detected quickly and accurately regardless of surrounding brightness. An imaging device includes: a photoelectric conversion element that photoelectrically converts incident light and generates an electrical signal corresponding to incident light intensity; a detection unit that outputs a detection signal indicating whether or not a change amount of the electrical signal exceeds a predetermined threshold value; and a threshold value selection circuit that selects the threshold value from among a plurality of threshold value candidates according to a magnitude of the electrical signal.
