Abstract:
An imaging device includes: a photoelectric converter including a first electrode, a second electrode, and a photoelectric conversion layer that generates a signal charge; a charge accumulator connected to the first electrode to accumulate the signal charge; a first voltage supply circuit connected to the second electrode and that selectively supplies at least two different voltages including a first voltage and a third voltage greater than the first voltage; and a second voltage supply circuit that is connected to the charge accumulator via capacitance and that selectively supplies at least two different voltages including a second voltage and a fourth voltage less than the second voltage, where in a first period in which the first voltage supply circuit supplies the first voltage, the first period being included in an accumulation period for accumulating the signal charge in the charge accumulator, the second voltage supply circuit supplies the second voltage.
