    Abstract: An imaging device having unit pixel cells including a first unit pixel cell, the first unit pixel cell including a first electrode, a second electrode, a first photoelectric conversion layer for generating a first signal charge, and a first signal detection circuit connected to the first electrode for detecting the first signal charge. The imaging device further includes a voltage supply circuit which supplies a first voltage to the second electrode in a first period when the first unit pixel cell accumulates the first signal charge, a voltage of the second electrode on the basis of a voltage of the first electrode being positive in the first period, and the voltage supply circuit supplies a second voltage to at least one of the first electrode and the second electrode in a second period, the second period including a third period when a voltage of the second electrode is negative.

    Abstract: An imaging device including a pixel array including pixels, each pixel including a photoelectric converter including a first and second electrode, and a first photoelectric conversion layer between the first and second electrode, and a transistor having a gate coupled to the first electrode, the transistor outputting a signal corresponding to an amount of the signal charge collected by the first electrode. The device further including voltage supply circuitry coupled to the second electrode of each of the pixels, where the voltage supply circuitry, in each of consecutive frame periods, supplies a first voltage two or more times to form exposure periods in which the signal charge is collected by the first electrode, and supplies a second voltage one or more times to form non-exposure periods that separate the exposure periods from each other, and start time of each of the exposure periods is periodic over the consecutive frame periods.

    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.
