  • Patent number: 11962925
    Abstract: A photoelectric conversion apparatus includes a pixel, an A/D conversion portion and an output circuit. The pixel includes first and second photoelectric conversion portions and an accumulation portion configured to accumulate a signal charge in a location other than the photoelectric conversion portions. The A/D conversion portion is configured to perform A/D conversions on signals based on signal charges generated in the photoelectric conversions. The output circuit reads out first and second signals based on first and second signal charges accumulated in the first and second photoelectric conversion portions during an electric charge accumulation period and a third signal based on a third signal charge generated in the second photoelectric conversion portion and accumulated in the accumulation portion during the electric charge accumulation period. Conversion periods for analog-to-digital conversion to be performed on at least two of the first, second, or third signals have different lengths.
