Abstract
A photoelectric conversion device includes a first pixel including a photoelectric converter, a first node to which charge is transferred from the photoelectric converter, and a first transistor that resets a voltage of the first node, and configured to output a first signal in accordance with a voltage of the first node, a second pixel including a second node to which a predetermined voltage is supplied and a second transistor that resets a voltage of the second node, and configured to output a second signal in accordance with a voltage of the second node; and a control line connected to the first transistor and the second transistor. The first transistor resets the first node to a first voltage, and the second transistor resets the second node to a second voltage having a smaller amplitude than the first voltage.
