Abstract

A photoelectric conversion device includes a photoelectric conversion element configured to generate a photon detection signal by avalanche multiplication; a circuit configured to control a first state in which a first terminal of the photoelectric conversion element is connected to a power-supply voltage and a second state in which resistance between the first terminal and the power-supply voltage is higher than in the first state; a counter circuit connected to the photoelectric conversion element; a waveform shaping circuit disposed between the photoelectric conversion element and the counter circuit; and a gating circuit connected between an output node of the waveform shaping circuit and an input node of the counter circuit and configured to control whether or not to input an output signal of the waveform shaping circuit to the counter circuit.
