Shake correcting device, shake correcting method and control program for implementing the method
Abstract:
A shake correcting device is capable of preventing a correcting optical device from hitting against a component part in the vicinity thereof to generate noise upon outputs from an H bridge driver for driving the correcting optical device being enabled. The device includes an angular velocity sensor that detects shaking of an image pickup apparatus, a position sensor that detects the current position of a shift lens movably disposed for optically correcting the shaking of the apparatus, an H bridge driver that drives the lens according to a drive target value, and an integrator that generates a target correction value based on the output from the angular velocity sensor. The drive target value is calculated based on the target correction value and output data from the position sensor.
