ABSTRACT:
An image stabilizing apparatus is provided with a plurality of gain setting means arranged in a feedback loop system, a gain switching means for, when an oscillation of the feedback loop system is detected based on an output from a deviation amount detection means, switching gains in the gain setting means, a plurality of phase compensation means arranged in the feedback loop system, and a phase compensation switching means for, when an oscillation of the feedback loop system is detected based on an output from the deviation amount detection means, switching the phase compensation means. The oscillation is suppressed by switching the gains in the gain setting means, switching the phase compensation means, or simultaneously switching them.
