Abstract
A photoelectric conversion apparatus includes a waveform shaping circuit, a reference circuit, and a counter. The waveform shaping circuit is configured to generate a first pulse signal based on a signal output from an avalanche diode. The reference circuit is configured to generate a second pulse signal without depending on incident light. The counter is connected to the waveform shaping circuit and the reference circuit to count a number of occurrences of a pulse signal. The pulse signal is based on at least one of the first pulse signal and the second pulse signal, and is input to the counter.
