LIGHT DETECTION ELEMENT AND LIGHT DETECTION DEVICE

Abstract: to reduce consumed electric power in a light detection element. the light detection element includes a photoelectric conversion section, a disconnection section, and a recharge section. in this light detection element, the disconnection section connects the photoelectric conversion section and a predetermined detection node in a predetermined connection period and disconnects the photoelectric conversion section from the detection node in a wait period not corresponding to the connection period. moreover, in the light detection element, the recharge section supplies a predetermined voltage to the detection node over a predetermined period from a predetermined recharge start timing in the connection period.
