Abstract
A photoelectric conversion apparatus includes a photodiode, a counter, a control circuit. The photodiode is configured to cause avalanche multiplication. The counter is configured to generate a count signal as a result of counting a pulse generated by the avalanche multiplication during a predetermined period. The control circuit is configured to perform control to bring the photodiode into a waiting state in which the avalanche multiplication is possible and a stop state in which the avalanche multiplication is stopped, based on the count signal during a predetermined period.
