IMAGING DEVICE

PROBLEM TO BE SOLVED: To provide an imaging device that makes it possible to reduce a time required for the re-start of imaging operation after photographing.SOLUTION: An imaging device starts a charge operation after the start of a read-out operation of image signals and before completion of the read-out of the image signals; and changes a time interval from the start of the read-out operation of the image signals to the start of the charge operation on the basis of a power source voltage detected by voltage detection means so that the blade group releases the opening while leading edges of the blade group are separated from a read-out position of the image signals by a predetermined distance during the charge operation.
