Classification: CPC H | IPC H

Claim 0:
1. A photoelectric conversion apparatus comprising:
a pixel including a first photoelectric conversion portion, a second photoelectric conversion portion, an accumulation portion configured to accumulate a signal charge in a location other than the first photoelectric conversion portion and the second photoelectric conversion portion and an output circuit; and
an analog-to-digital conversion circuit configured to perform an analog-to-digital conversion on a signal based on a signal charge generated in the first photoelectric conversion portion and on a signal based on a signal charge generated in the second photoelectric conversion portion,
wherein the output circuit reads out a first signal based on a first signal charge accumulated in the first photoelectric conversion portion during an electric charge accumulation period, a second signal based on a second signal charge accumulated in the second photoelectric conversion portion during the electric charge accumulation period, and a third signal based on a third signal charge, the third signal charge being generated in the second photoelectric conversion portion and accumulated in the accumulation portion during the electric charge accumulation period, and
wherein conversion resolutions for analog-to-digital conversion to be performed on at least two of the first, second, or third signals are different.
