1. An image stabilization apparatus that reduces image blurring by moving a correction mechanism in accordance with a motion of an image capture apparatus, the image stabilization apparatus comprising one or more processors that execute a program and thereby function as:
a control unit configured to control a movement of the correction mechanism in accordance with a target position of the correction mechanism, the target position being intended to reduce the image blurring;
a detection unit configured to detect a vibration of a preset frequency included in the motion, the preset frequency being higher than a first frequency of a vibration caused by a camera shake; and
a changing unit configured to, in a case where the vibration of the preset frequency has been detected, reduce a control gain used for controlling the movement of the correction mechanism compared to a case where the vibration of the preset frequency has not been detected.
