Abstract
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.
