Patent ID: 8514290

Claim:
An image-blur correction apparatus comprising: an image capturing unit configured to capture an object image; a camera-shake detection unit configured to detect a camera-shake applied to the image-blur correction apparatus; a target position determination unit configured to determine a correction target position of a correction member based on a camera-shake signal detected by the camera-shake detection unit; a correction unit configured to correct the camera-shake of the object image by moving the correction member to the correction target position; a measuring unit configured to measure an amplitude of the camera-shake or a frequency of the camera-shake based on the camera-shake signal supplied from the camera-shake detection unit; a memory configured to store a correction target position determined by the target position determination unit when it is first determined that the measured amplitude is less than a predetermined amplitude or when it is first determined that the measured frequency is less than a predetermined frequency; and a control unit configured to hold the correction member at the stored correction target position until it is determined that the measured amplitude is greater than a second amplitude or the measured frequency is greater than a second frequency.
