PURPOSE:To eliminate the need of a reset IC added to a shake correction controller and to suppress the quantity of a current consumed by a shake correction device, a driving device and the shake correction controller even when the malfunction of the shake correction controller occurs. CONSTITUTION:The whole sequence of a camera is controlled by a one-chip microcomputer constituted of an A-microcomputer 1 and a B-microcomputer 2. The A-microcomputer 1 corresponds to the main controller and executes photographing processing other than shake correcting control. Besides, it is the main microcomputer controlling the B-microcomputer 2. The B- microcomputer 2 corresponds to a shake correction control circuit and it is the sub-microcomputer executing the shake correction control. Besides, shake detection circuits 9 and 10, motor driving circuits 11 and 12 and lens position detection circuits 19 and 20 are connected to the B-microcomputer 2 and the shake correction control is executed. |
