Image pickup apparatus including image shake correction

An image pickup apparatus comprising:

• a rotation shake detection unit configured to detect a rotation shake generated in a direction not parallel with an optical axis of the image pickup apparatus;
• a first processing unit configured to process a detection signal of the rotation shake into a first correction amount;
• a translational shake detection unit configured to detect a translational shake generated in a direction perpendicular to an optical axis of the image pickup apparatus;
• a second processing unit configured to process a detection signal of the translational shake into a second correction amount;
• a shake correction unit configured to correct an image shake generated on an image plane of an image pickup apparatus based on the first correction amount and the second correction amount;
• an initialization unit configured to initialize an integrated correction amount which is obtained by integrating the first correction amount with the second correction amount;
• and
• a control unit configured to instruct the initialization unit to initialize, based on an image pickup start instruction of the image pickup apparatus, prior to a photographing operation, the integrated correction amount to move the shake correction unit.
