Abstract
A photoelectric conversion device includes a detector, a switch, a first circuit, a second circuit, a counter, and a selector. The detector generates change in voltage by current based on incident photons. The switch is between the detector and a node. The first circuit generates a first detection signal based on the change in response to the photon in the detector during a period when the switch is in the ON state. The second circuit generates a second detection signal based on the change in the detector during periods when the switch is in the ON and OFF states. The counter counts the signal to output a count value. The selector selects one of the first and second detection signals generated by the one of the first and second circuits and output a selected detection signal to the counter.
