Image capture apparatus and control method therefor

An image capture apparatus comprising:

• a first shake detection unit configured to detect a shake of said image capture apparatus;
• a rotational shake calculation unit configured to calculate a rotational shake amount based on an output of said first shake detection unit;
• a second shake detection unit configured to detect the shake of said image capture apparatus by a method different from that of said first shake detection unit;
• a translational shake calculation unit configured to calculate a translational shake amount based on the output of said first shake detection unit and an output of said second shake detection unit;
• a correction amount calculation unit configured to calculate, based on the rotational shake amount and the translational shake amount, a correction amount for correcting image blurring of an image;
• and
• a correction unit configured to correct the image blurring based on a calculation result of said correction amount calculation unit,
• wherein said rotational shake calculation unit calculates a first translational motion component and perspective component using the rotational shake amount, and the first translational motion component is a translational motion component of image blurring generated in a captured image due to a rotational shake, and
• wherein said correction amount calculation unit calculates a second translational motion component based on the first translational motion component and the translational shake amount, and the second translational motion component is a translational motion component of image blurring generated in the captured image due to the rotational shake and a translational shake.
