    Abstract: An imaging device including a photoelectric converter including a first electrode, a second electrode, and a photoelectric conversion layer; a voltage supply circuit that applies a bias voltage between the first electrode and the second electrode; an amplifier transistor including a gate electrically connected to the second electrode, the amplifier transistor being configured to output a signal that corresponds to a potential of the gate; and a detection circuit that is configured to detect a level of the signal from the amplifier transistor. The voltage supply circuit applies the bias voltage in a first voltage range, in a case where the level detected by the detection circuit is less than a first threshold value, and applies the bias voltage in a second voltage range that is greater than the first voltage range, in a case where the level detected by the detection circuit is greater than a second threshold value.

    Abstract: An imaging device including pixels having a photoelectric converter including a first and second electrode, a photoelectric conversion layer; a charge accumulation region electrically connected to the first electrode; and a signal detection circuit. The photoelectric converter is applied with a voltage between the first electrode and the second electrode, and the photoelectric converter has a characteristic, responsive to the voltage within a range from a first voltage to a second voltage, showing that a density of current passing between the first electrode and the second electrode when light is incident on the photoelectric conversion layer becomes substantially equal to that when no light is incident on the photoelectric conversion layer. A difference between the first voltage and the second voltage is 0.5 V or more, and the voltage supply circuit supplies a voltage between the first voltage and the second voltage to the second electrode in a non-exposure period.
