Abstract
A photoelectric conversion device includes a plurality of pixels arranged in an array to form a plurality of rows and a plurality of columns. Each of the plurality of pixels includes a photon detection element that outputs an output signal generated by avalanche multiplication in accordance with incidence of a photon, a quench element connected to the photon detection element, a waveform shaper that is connected to the photon detection element and generates a detection signal based on the output signal, and a signal processing circuit that performs signal processing on the detection signal output from the waveform shaper. The signal processing circuit includes a counting unit that performs a counting process of counting the detection signal output from the waveform shaper, and a calculation unit that performs a predetermined calculation process on a count result output from the counting unit.
