1. A photoelectric conversion device comprising:
a plurality of pixels each including a photoelectric conversion unit and a counting unit configured to generate a count value based on incident light to the photoelectric conversion unit; and
a calculation unit configured to perform interpolation processing on the count value,
wherein each of the plurality of pixels is controlled to either a first state in which generation of the count value based on the incident light is enabled or a second state in which generation of the count value based on the incident light is disabled,
wherein the plurality of pixels includes a first pixel and a second pixel,
wherein in a first sub-frame period in one frame period, the first pixel is controlled to the first state, and the second pixel is controlled to the second state,
wherein in a second sub-frame period in the one frame period, the second pixel is controlled to the first state, and the first pixel is controlled to the second state, and
wherein the calculation unit calculates a second count value of the first pixel in the second sub-frame period by performing the interpolation processing using a first count value generated in the second pixel in the second sub-frame period.
