PHOTOELECTRIC CONVERSION DEVICE AND METHOD OF DRIVING PHOTOELECTRIC CONVERSION DEVICE

A photoelectric conversion device includes pixels each including a plurality of photoelectric conversion elements and arranged in a matrix, and a control circuit that controls the pixels on row-by-row. Each pixel may output a first signal corresponding to charge generated by the first photoelectric conversion element and a second signal corresponding to charge generated by the first and second photoelectric conversion elements. The control circuit performs a first reset operation and a first readout operation for reading out the second signal on pixels in a first row, and performs a second reset operation, a second readout operation for reading out the first signal, and a third readout operation for reading out the second signal on pixels in a second row. The control circuit performs a third reset operation on pixels of any one of rows in a period one before a period during which the second reset operation is performed.
