<p>PROBLEM TO BE SOLVED: To provide a function of switching between assignment for correction in a high frequency band and assignment for correction in a low frequency band in an image blur correction device which separates a shake detection signal into respective components in the high frequency band and the low frequency band and then controls a plurality of image blur correction units.SOLUTION: An image blur correction device 100 includes an angular velocity sensor 101, and a frequency separation unit 103 separates a shake detection signal into a low frequency signal and a high frequency signal by a digital filter. A first image blur correction unit 107 performs image blur correction based on one of the high frequency signal and the low frequency signal, and a second image blur correction unit 111 performs image blur correction based on the other. A frequency separation control unit 112 switches the digital filter between high pass characteristics and low pass characteristics to change frequency assignment to the first image blur correction unit 107 and the second image blur correction unit 111.</p> |
