Abstract: An imaging device includes: a photoelectric converter including first and second electrodes, and a photoelectric conversion layer located between the first electrode and the second electrode; a voltage supply circuit applying 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 configured to output a signal corresponding to a potential of the second electrode; and a detection circuit 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 when the level detected by the detection circuit is greater than or equal to a first threshold value, and applies the bias voltage in a second voltage range that is greater than the first voltage range when the level detected by the detection circuit is less than a second threshold value.

Abstract: An imaging device includes at least one unit pixel cell including a photoelectric converter and a voltage application circuit. The photoelectric converter includes a first electrode, a light-transmitting second electrode, a first photoelectric conversion layer containing a first material and a second photoelectric conversion layer containing a second material. The impedance of the first photoelectric conversion layer is larger than the impedance of the second photoelectric conversion layer. The voltage application circuit applies a first voltage or a second voltage having a larger absolute value than the first voltage selectively between the first electrode and the second electrode.

Abstract: An imaging device including: a photoelectric converter including first and second electrodes and a conversion layer therebetween; a voltage supplier; an outputter outputting a signal indicating the potential of the second electrode; and a detector detecting the signal level, in which the change rate of the conversion efficiency of the photoelectric converter with respect to a bias voltage, applied between the electrodes, when the bias voltage is in a first range is greater than when the bias voltage is in a second range greater than the first range, and the voltage supplier, when the detected level is less than a first threshold, causes the potential difference between the electrodes to become a first difference, and, when the detected level is greater than or equal to a second threshold greater than or equal to the first threshold, causes the potential difference to become a second difference greater than the first difference.
