An image stabilizing system performs rotational-shake correction to increase focus precision so that shift shake correction can be performed with high precision based on highly accurate image magnification information obtained by the high focus precision. The image stabilizing system includes a rotational-shake detecting unit that detects rotational shake occurring around a shooting light axis of an optical apparatus; a parallel-shake detecting unit that detects parallel shake occurring within a plane orthogonal to the light axis; a shake correcting unit that reduces image deterioration caused by the rotational shake and parallel shake; and an image stabilizing unit that actuates the shake correcting unit at an initial stage of a shake correcting process based on an output signal from the rotational-shake detecting unit, and actuates the shake correcting unit at a subsequent stage of the shake correcting process based on output signals from the rotational-shake detecting unit and the parallel-shake detecting unit.
