Abstract
The image stabilization control apparatus that performs, using a shake detection signal acquired through a shake detector configured to detect a shake and a motion vector detection signal indicating a motion vector detected in a video signal produced through an image sensor, image stabilization control for reducing image blur due to the shake. The apparatus includes a predictor that produces, using the motion vector detection signal, a predicted error signal that indicates a predicted value of an error signal included in the shake detection signal, a signal producer that subtracts the predicted error signal from the shake detection signal to produce a first image stabilization signal, and a controller that performs the image stabilization control using the first image stabilization signal.
