1. A photoelectric conversion device comprising:
a photoelectric conversion unit including one microlens and a plurality of photoelectric conversion elements;
a signal line configured to transmit a signal from the photoelectric conversion unit;
a readout circuit electrically connected to the signal line, and configured to read out a first signal based on charges accumulated by a first photoelectric conversion element of the plurality of photoelectric conversion elements and a second signal based on charges accumulated by a second photoelectric conversion element of the plurality of photoelectric conversion elements; and
a signal processing circuit electrically connected to the readout circuit, and configured to, (1) generate a determination result based on at least one of a level of the first signal and a level of the second signal, (2) output a third signal obtained by adding the first signal and the second signal in a case when the determination result indicates that the at least one of the level of the first signal and the level of the second signal is smaller than a predetermined signal level, and (3) output a fourth signal having a level relating to the determination result in a case when the determination result indicates that the at least one of the level of the first signal and the level of the second signal is larger than the predetermined signal level.
