Abstract
An imaging device including a pixel including: a photoelectric converter including a first electrode, a second electrode, and a photoelectric conversion film between the first electrode and the second electrode, the photoelectric conversion film converting light into a charge; a first transistor having a first source, drain and gate, the first gate connected to the first electrode; and a second transistor having a second source and drain, one of the second source and the second drain connected to the first electrode and being a charge accumulation region that accumulates the charge. The imaging device further including a first voltage supply circuit supplying a first voltage to the second electrode, where the second transistor has a characteristic that when a voltage of the charge accumulation region is equal to or greater than a clipping voltage, the second transistor is turned off, and the clipping voltage is lower than the first voltage.
