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.

Abstract: An imaging device 100 includes a pixel array PA. A first period, a third period, and a second period appear in this order in a first frame. During the first period, pixel signal readout is performed on a first row in the pixel array PA. During the second period, pixel signal readout is performed on a second row in the pixel array PA. Each of the first period and the second period is a high-sensitivity exposure period. The third period is a low-sensitivity exposure period.

Abstract: An imaging system includes a first illuminator that emits light whose intensity varies with time; and a first imaging device that comprises a first imaging cell; and a first bias control line. The first imaging cell includes a first electrode, a second electrode electrically connected to the first bias control line, and a photoelectric conversion layer sandwiched between the first electrode and the second electrode. During a first period from a reset of the first imaging cell until a readout of signal charge accumulated in the first imaging cell, the first bias control line supplies to the second electrode a first bias control signal. The first bias control signal is synchronized with the intensity of the light varying with time.
