Abstract
A photoelectric conversion device including a pixel equipped with a photoelectric conversion circuit configured to output a signal in response to incidence of a photon includes a first measurement circuit, a second measurement circuit, a selection circuit, and a selection circuit. The first measurement circuit is configured to measure the signal output from the pixel. The second measurement circuit is configured to measure time from when the first measurement circuit starts measuring the signal until a measured value measured by the first measurement circuit reaches a first threshold value. The selection circuit is configured to switch a first measurement circuit to be connected to the second measurement circuit among a plurality of first measurement circuit. The control circuit is configured to control timing of switching a connection of the second measurement circuit by the selection circuit.
