ABSTRACT:
In a monitor mode, the saturated electric charge amount of a plurality of first, second, third, and fourth types of photoelectric conversion elements disposed in matrix form on a semiconductor substrate is set to one half a saturated electric charge amount during a still mode. In the monitor mode, electric charges stored by two of the four types of photoelectric conversion elements are transferred to vertical CCDs, mixed and vertically transferred to a horizontal CCD. In the still mode, electric charges of one of the four types of photoelectric conversion elements at a time for a 1 V period (where V is a vertical scan period) are transferred to vertical CCDs and vertically transferred to the horizontal CCD. Furthermore, in the still mode, initially, the electric charges in the photoelectric conversion elements are cleared out for 4n * V periods, where n is a positive integer. Thereafter, smear electric charges are swept out from the vertical CCDs during a 1 V period.
