Shake compensation apparatus, shake compensation control method, and image capturing apparatus and control method thereof

摘要

A shake compensation apparatus includes a shake compensation unit configured to compensate the shake by moving non-parallel to an optical axis; a driving unit configured to drive the shake compensation unit based on a drive indication signal; a position detection unit configured to detect the position of the shake compensation unit to output a position detection signal; and a compensation amount calculation unit configured to detect translational shake component in the shake of the apparatus from the movement of the shake compensation unit such that the drive indication signal and the position detection signal serve as input, and calculate the compensation amount of the shake compensation unit from the shake amount of the apparatus including the translational shake component to output it as a drive indication signal.

1. A shake compensation apparatus configured to compensate a shake, the apparatus comprising:
a shake compensation unit configured to be moved non-parallel to an optical axis to compensate the shake; a driving unit configured to drive the shake compensation unit based on a drive indication signal; a position detection unit configured to detect a position of the shake compensation unit to output a position detection signal; and a compensation amount calculation unit configured to:
detect a translational shake component in the shake of the apparatus from the movement of the shake compensation unit based on the drive indication signal and the position detection signal; andcalculate a compensation amount of the shake compensation unit from a shake amount of the apparatus including the translational shake component and output it as the drive indication signal to the driving unit.
