Photoelectric conversion device

A photoelectric conversion device comprising:

• a pixel array in which a plurality of pixels are arranged to form a plurality of rows and a plurality of columns, each of the plurality of pixels including a charge accumulation unit configured to accumulate charge, a discharge transistor configured to perform a reset operation to discharge the charge accumulated in the charge accumulation unit, a holding unit configured to hold transferred charge, an amplification unit configured to output a signal based on the transferred charge, a first transfer transistor configured to transfer the charge from the charge accumulation unit to the holding unit, and a second transfer transistor configured to transfer the charge transferred by the first transfer transistor to the amplification unit;
• and
• a scanning circuit configured to perform scanning for sequentially selecting a row in which the pixels output signals, from among the plurality of rows,
• wherein a first pixel arranged in a first region of the pixel array outputs a signal based on incident light,
• wherein a second pixel arranged in a second region of the pixel array does not output a signal based on incident light,
• wherein in a period in which pixels in one row of the pixel array output signals, the reset operation by the discharge transistor is started or ended, and
• wherein in a period from a start of one scan to a start of the next scan, number of times of the reset operation performed in the second pixel is greater than number of times of the reset operation performed in the first pixel.
