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.

Imaging device and imaging method

In an imaging device that transmits control signals to a large number of pixels, an influence is reduced of delay at the time of signal transmission. An imaging device drive circuit includes a plurality of control signal lines, a control signal distribution line, two control signal transmission units, and two operation units. The plurality of control signal lines each transmits a control signal for each of a plurality of pixels that generates image signals depending on incident light on the basis of the control signal. The control signal distribution line has a shape of a line, and the plurality of control signal lines is connected thereto in a distributed manner, and the control signal distribution line distributes the control signals supplied from both ends of the line to the plurality of control signal lines.
