Image pickup apparatus and control method thereof

An image pickup apparatus capable of combining a plurality of continuously captured images, comprising:

• at least one processor and at least one memory functioning as:
• a first detection unit configured to detect shake of the image pickup apparatus;
• a second detection unit configured to detect a moving amount of a captured image captured by an imaging unit;
• a correction unit configured to correct image blur of an image caused by shake of the image pickup apparatus;
• a control unit configured to calculate a blur amount of a target in the captured image from a shake detection signal detected by the first detection unit and the moving amount detected by the second detection unit and to control image blur correction performed by the correction unit;
• and
• a combining unit configured to combine a plurality of captured images with corrected image blur,
• wherein the control unit switches first control of controlling the correction unit using a correction amount calculated from the shake detection signal and second control of controlling the correction unit using a correction amount calculated from the shake detection signal and the moving amount, depending on detection reliability of the moving amount or a continuous shooting speed.
