Abstract
A first correction signal creation unit splits an angular velocity signal of an ultra low-low frequency band from an angular velocity signal of an X-axis angular velocity sensor and outputs a first correction signal amplified based on signal output characteristics of the angular velocity sensor. A second correction signal creation unit splits an angular velocity signal of a low-high frequency band from the angular velocity signal and outputs a second correction signal amplified based on the signal output characteristics of the angular velocity sensor. An addition computation unit creates a composite correction signal in which the first correction signal and the second correction signal are composed, and a drive computation unit creates a drive signal based on the composite correction signal. A driver drives the X-axis actuator based on the drive signal, displaces the correction optical element, and corrects shake of an image.
