Photoelectric conversion device

A photoelectric conversion device comprising:

• a plurality of avalanche photodiodes arranged two-dimensionally;
• a plurality of accumulating circuits arranged so as to correspond to the plurality of avalanche photodiodes;
• and
• an interpolation unit configured to perform interpolation processing using pixel values generated in each of the plurality of accumulating circuits,
• wherein the plurality of accumulating circuits include a plurality of first accumulating circuits respectively configured to receive output signals based on incident light to a plurality of first avalanche photodiodes among the plurality of avalanche photodiodes, and a plurality of second accumulating circuits respectively configured to receive output signals based on incident light to a plurality of second avalanche photodiodes among the plurality of avalanche photodiodes,
• wherein the plurality of first accumulating circuits generate, based on output signals of the plurality of first avalanche photodiodes, a plurality of first pixel values by accumulating values weighted by a first weight that varies in a predetermined cycle,
• wherein the plurality of second accumulating circuits generate, based on output signals of the plurality of second avalanche photodiodes, a plurality of second pixel values by accumulating values weighted by a second weight that has values different from the first weight and that varies in a predetermined cycle, and
• wherein the interpolation unit generates, by interpolation processing using a part of the plurality of first pixel values, a first interpolation pixel value at first representative coordinates of a first avalanche photodiode corresponding to a first pixel value used in the interpolation processing.
