Abstract
A photoelectric conversion apparatus includes a first pixel and a second pixel, each of which includes a photodiode, and a signal processing circuit including a control circuit and a counter. The control circuit is connected to the photodiode and a circuit configured to generate a pulse signal, and performs control, based on the pulse signal, so as to be in a standby state or a recharge state. The counter counts the number of periods in which avalanche multiplication has occurred in the standby state. A third pulse of the pulse signal for the second pixel is input to the control circuit in a period from when a first pulse of the pulse signal for the first pixel is input to the control circuit to when a second pulse of the pulse signal for the first pixel subsequent to the first pulse is input to the control circuit.
