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.
