Abstract
A photoelectric conversion apparatus includes a pixel and a counter circuit. The pixel includes a first avalanche photodiode and a second avalanche photodiode having different sensitivity to light. The counter circuit is configured to count a first signal based on charges generated in the first avalanche photodiode, and a second signal based on charges generated in the second avalanche photodiode. Processing on the count value is different between a case where a count value output from the counter circuit is larger than a threshold value and a case where the count value output from the counter circuit is smaller than the threshold value.
