Patent ID: 7675548

Claim:
A shake correcting device that corrects shaking of an object image picked up by an apparatus, comprising: a correcting optical device that is movably disposed for optically correcting the shaking of the apparatus, to which said shake correcting device is attached; a position detecting device that detects and outputs a current position of said correcting optical device; a shake detecting device that detects shaking of the apparatus and outputs a signal representing the detected shaking of the apparatus, wherein said shake detecting device comprises an angular velocity sensor that outputs the signal representing the detected shaking of the apparatus; a target data-generating device that generates target correction data based on an output from said shake detecting device; a drive signal-calculating device that calculates a drive signal based on the target correction data and output data from said position detecting device; a driving device that drives said correcting optical device according to the drive signal; and an output control device that controls enabling and disabling of an output from said driving device, wherein said output control device includes a switching device that sets the output data from said position detecting device to the target correction data, for a time period after said output control device has enabled the output from said driving device before the output of said shake detecting device becomes stable, and sets the target correction data based on the output from said shake detecting device and a predetermined time constraint, after the output of said shake detecting device has become stable.
