Patent ID: 7809257

Claim:
An anti-shake apparatus for image stabilization of a photographing device, comprising: a movable unit that has an imaging device and is movable and rotatable for an anti-shake operation; a controller that controls said movable unit for said anti-shake operation, said controller calculating a first hand-shake angle in the direction of yaw, a second hand-shake angle in the direction of pitch, and a third hand-shake angle in the direction of roll for said anti-shake operation, said controller commencing a calculation of said third hand-shake angle from a first time point after a release switch is set to the ON state, and said controller commencing calculations of said first and second-hand shake angles from a second time point after said first time point, and before an exposure operation commences; and first and second position-detection devices that are used for detecting a position of said movable unit in a predetermined direction; wherein said controller calculates a rotational direction component of a position of said movable unit for said anti-shake operation, on the basis of said third hand-shake angle and a relative distance between said first position-detection device and said second position-detection device, after said first time point.
