ABSTRACT:
An apparatus includes a control unit for switching image blur prevention operations between a first image blur prevention operation and a second image blur prevention operation with respect to the same image blur state in accordance with a start of a photographing operation. For example, the control unit performs control to switch modes between a mode of performing a prevention operation by an operation amount required to attain correction, and a mode of performing a prevention operation by an operation amount smaller than the required operation amount to leave room for correction. This switching operation is performed independently of an image blur frequency. For example, a gain is evenly changed at all frequencies. With this arrangement, the operability of the apparatus can be improved.
