1. A camera system comprising:
a photoelectric converter including a first electrode, a second electrode, and a photoelectric conversion layer between the first electrode and the second electrode, the photoelectric conversion layer converting incident light into electric charge;
voltage application circuitry that supplies a first voltage and a second voltage less than the first voltage between the first electrode and the second electrode such that the first voltage is applied at least one time in a frame; and
a controller that derives a total length of at least one period in which the first voltage is applied in the frame, the total length corresponding to an attenuation ratio set for the frame, and causes the voltage supply circuitry to supply the first voltage in the at least one period having the total length in the frame.
