Detection information for shake is detected by a shake detection unit, predictive shake information is calculated based on the shake detection information, a start position (center) of a correcting operation on an imaging surface of a shake correction unit is determined, and driving of the shake correction unit at the correcting-operation start position is controlled. Accordingly, it is possible to make effective use of a movable range of the shake correction unit for actual hand shake or the like. Thus, a high degree of correction effect can be obtained, so that imaging failures due to hand shake or the like can be remarkably reduced.
