Abstract: An imaging device includes a first pixel, a second pixel, and a first voltage supply circuit. The first pixel includes a first photoelectric converter that generates signal charge by photoelectric conversion and a first signal detection circuit connected to the first photoelectric converter. The second pixel includes a second photoelectric converter that generates signal charge by photoelectric conversion and a second signal detection circuit connected to the second photoelectric converter. The first photoelectric converter includes a first pixel electrode, a first counter electrode facing the first pixel electrode, and a first photoelectric conversion layer located between the first pixel electrode and the first counter electrode. A voltage that the first voltage supply circuit applies between the first pixel electrode and the first counter electrode is switched between a plurality of voltages in part of a one-frame period excluding a readout period and a reset period of the second photoelectric converter.
