A photoelectric conversion apparatus includes a first pixel, a second pixel, and an offset adding circuit. The first pixel includes a first avalanche photodiode and a first count circuit. The first count circuit is configured to count a first signal that is based on the number of photons that have entered the first avalanche photodiode. The second pixel includes a second avalanche photodiode and a second count circuit. The second count circuit is configured to count a second signal that is based on the number of photons that have entered the second avalanche photodiode. The offset adding circuit is configured to set an offset value for each of the first count circuit and the second count circuit. The first count circuit starts a first counter operation from a first offset value. The second count circuit starts a second counter operation from a second offset value.

A plurality of comparison circuits each including a first terminal for inputting a first analog signal and a second analog signal and a second terminal connected to a wiring for transmission of a ramp signal A first operation changes an electric potential of the wiring from a predetermined electric potential to a first electric potential to cause at least one of the plurality of comparison circuits to retain a first offset. A second operation, after the first operation, converts the first analog signal into a digital signal. A third operation, after the second operation, changes the electric potential of the wiring to an electric potential included in a range of from the predetermined electric potential to the first electric potential. A fourth operation, after the third operation, converts the second analog signal into a digital signal.
