Abstract
The image stabilization control apparatus includes a shake extracting unit extracting a first shake signal whose frequency is higher than a predetermined frequency from a shake detection signal, a predicting unit producing, by using a motion vector detection signal, a predicted shake signal indicating a predicted value of shaking of an optical apparatus, a combining unit combining the first shake signal with the predicted shake signal to produce a second shake signal, a controlling unit performing an image stabilization control using the second shake signal, and a motion vector extracting unit extracting a specific motion vector signal whose frequency is lower than the predetermined frequency from the motion vector detection signal. The controlling unit performs the image stabilization control using the second shake signal in still image capturing, and the predicting unit produces the predicted shake signal by using the specific motion vector signal.
