Abstract
A photoelectric conversion apparatus includes a pixel including a photoelectric conversion circuit configured to output a signal corresponding to photon incidence. The photoelectric conversion apparatus further includes a first measurement circuit, a second measurement circuit, a selection circuit, and an output circuit. The first measurement circuit is configured to measure the signal output from the pixel. The second measurement circuit is configured to measure a time from when the first measurement circuit starts measuring the signal to when a measured value of 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 the first measurement circuits. The output circuit is configured to output a value of the measured time of the second measurement circuit.
