<p>PROBLEM TO BE SOLVED: To attain an excellent image blur correction even when a large shakiness occurs due to a pan or tilt operation, or the like.SOLUTION: An image device determines a target position of a blur correction lens in accordance with an applied shakiness, and performs a feed-back control so as to converge the position of the blur correction lens to the target position. Division means divides a blur signal into a low frequency component and a high frequency component. A first low-pass filter performs integration processing of the high frequency component, and a second low-pass filter performs integration processing of the low frequency component. Composition means composes an output signal of the first low-pass filter with an output signal of the second low-pass filter, and outputs the composed signal as the target position. When it is determined that the imaging device is during panning or tilting, a cut-off frequency of the second low-pass filter is set at a higher value than the cut-off frequency which the imaging device is not during the panning or tilting.</p> |
