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, an addition circuit, and a second measurement circuit. The first measurement circuit is configured to measure the signal output from the pixel. The addition circuit is configured to add measured values of a plurality of the first measurement circuits. The second measurement circuit is configured to measure a time from when each of the plurality of first measurement circuits starts measuring the signal to when the measured values added by the addition circuit reach a first threshold value.
