Abstract
An image stabilizing apparatus includes at least one processor or circuit configured to execute a plurality of tasks including a first calculation task configured to make a calculation using an output signal from a shake detector configured to detect a shake, a second calculation task configured to estimate an estimated value corresponding to an offset variation value included in the output signal from the shake detector by using a signal processed by a low-pass filter having a high-frequency attenuation characteristic steeper than a high-frequency attenuation characteristic of the first calculation task, and a correction task configured to drive a corrector configured to correct an image blur caused by the shake using a calculation result of the first calculation task and the estimated value.
