Image stabilization apparatus, control method thereof, and storage medium

A control method of an image stabilization apparatus that includes a supporting device that supports an image capturing device that captures an object image formed by an imaging optical system, and a rotation device that rotates the supporting device in two axis directions, said method comprising:

• calculating a residual correction amount of image blur after mage blur correction is performed by a first image blur correction device that corrects image blur on an imaging plane of the image capturing device caused by shake of the apparatus by driving the rotation device, based on output of a shake detection device that detects shake of the apparatus and a moving amount of the first image blur correction device;
• correcting the residual correction amount of image blur, by a second image blur correction device that corrects the residual correction amount of image blur using a method different from that of the first image blur correction unit device;
• and
• changing allocation between a correctable range of the second image blur correction device correcting image blur in a horizontal or vertical direction on the aging plane of the image capturing device and a correctable range of the second image blur correction device correcting image blur in a rotation, direction on the imaging plane, based on a rotation angle of the rotation device and the residual correction amount oaf image blur.

A non-transitory computer-readable storage medium that stores a program for causing a computer to execute steps of a control method of an image stabilization apparatus that includes a supporting device that supports an image capturing device that captures an object image formed by an aging optical system, and a rotation device that rotates the supporting device in two axis directions, said method comprising:

• calculating a residual correction amount of image blur after image blur correction is performed by a first image blur correction device that corrects age blur on an imaging plane of the image capturing device caused by shake of the apparatus by driving the rotation device, based on output of a shake detection device that detects shake of the apparatus aid a moving amount of the first image blur correction device;
• correcting the residual correction amount of image blur, by a second image blur correction device that corrects the residual correction amount of image blur using a method different from that of the first image blur correction device;
• and
• changing allocation between a correctable range of the second image blur correction device correcting image blur in a horizontal or vertical direction on the imaging plane of the image capturing device and a correctable range of the second image blur correction device correcting image blur n a rotation direction on the aging plane, based on a rotation angle of the rotation device and the residual correction amount of it age blur.
