Abstract:
1. A photoelectric conversion device comprising: a light detection circuit comprising an optical sensor and a current-voltage conversion circuit; a comparison circuit configured to compare an output voltage of the light detection circuit to a reference voltage; and a control circuit electrically connected to the current-voltage conversion circuit and configured to output a control signal based on an output signal of the comparison circuit, wherein the current-voltage conversion circuit comprises a first resistor having a first resistance value, a second resistor having a second resistance value different from the first resistance value, and a switch, wherein the switch is controlled based on the control signal, wherein the optical sensor is electrically connected to at least one of the first resistor and the second resistor, wherein an output of the light detection circuit is electrically connected to the optical sensor, and wherein the output of the light detection circuit is electrically connected to the current-voltage conversion circuit.
