Claim 13:
14. A method for driving an imaging device including a photoelectric converter that includes a second photoelectric conversion layer, a barrier layer, a first photoelectric conversion layer, and a counter electrode are stacked on a pixel electrode in this order, the barrier layer forming a heterojunction barrier against first signal charge generated in the first photoelectric conversion layer, the method comprising:
(a) setting a potential difference between the pixel electrode and the counter electrode to a first potential difference, to cause a second signal charge generated in the second photoelectric conversion layer to be collected by the pixel electrode while the first signal charge is held in the first photoelectric conversion layer using the heterojunction barrier; and
(b) setting the potential difference between the pixel electrode and the counter electrode to a second potential difference which is larger than the first potential difference, to cause the first signal charge to pass through the heterojunction barrier and to be collected by the pixel electrode.
