Claim 34:
35. A photoelectric conversion apparatus comprising:
a pixel including a photoelectric conversion portion;
an accumulation portion configured to accumulate a signal charge generated in the photoelectric conversion portion in a location other than the photoelectric conversion portion;
an analog-to-digital conversion circuit configured to perform an analog-to-digital conversion on a signal based on the signal charge generated in the photoelectric conversion portion; and an output circuit,
wherein the output circuit reads out a first signal based on a first signal charge accumulated in the photoelectric conversion portion during an electric charge accumulation period and a second signal based on a second signal charge accumulated in the accumulation portion during the electric charge accumulation period, and
wherein conversion resolutions for analog-to-digital conversion to be performed on the first and second signals are different.
