1. A photoelectric conversion device comprising a plurality of pixels arranged to form a plurality of rows, a scanning circuit configured to drive the plurality of pixels, and a control circuit,
wherein the scanning circuit is configured to perform a driving operation including a first scan of causing the plurality of pixels to start an accumulation operation on a row basis and a second scan of reading out signals from the plurality of pixels on a row basis after the first scan,
the driving operation includes a first driving operation and a second driving operation that are different in a length of a readout period of signals from one row in the second scan,
the control circuit is configured to supply, to the scanning circuit, a first synchronization signal for controlling the first scan and a second synchronization signal for controlling the second scan, and
a relationship between a cycle of the first synchronization signal and the second synchronization signal supplied from the control circuit to the scanning circuit in the first driving operation and a cycle of the first synchronization signal and the second synchronization signal supplied from the control circuit to the scanning circuit in the second driving operation is a relationship of a non-integer multiple or a non-integral submultiple.
