Image stabilization control apparatus, image capturing apparatus, image capturing system, control method, and storage medium

An image capturing apparatus comprising:

• a detection unit configured to detect shake of the image capturing apparatus;
• a first correction unit and a second correction unit for correcting an influence of the shake detected by the detection unit, on a captured image, the first correction unit and the second correction unit employing different correction methods;
• an acquisition unit configured to acquire information regarding a shutter speed related to image capturing that is to be performed by the image capturing apparatus;
• and
• a control unit configured to perform control to cause the first correction unit and the second correction unit to correct shake detected by the detection unit, so as to change the allocation of correction of the shake to the first correction unit and the second correction unit based on information regarding the shutter speed acquired by the acquisition unit,
• wherein the second correction unit employs an electronic shake correction method, and corrects the shake by changing a region that is to be extracted from an image signal acquired through image capturing, and
• the control unit changes a movable area that can be used to extract the region from the image signal that is to be subjected to correction performed by the second correction unit, according to the shutter speed.

An image capturing system that includes an image stabilization control apparatus and an image capturing apparatus, the image capturing system comprising:

A method for controlling an image stabilization control apparatus, the method comprising:

• detecting shake of an image capturing apparatus;
• acquiring information regarding a shutter speed related to image capturing that is to be performed by the image capturing apparatus;
• and
• performing control to cause a first correction unit and a second correction unit that respectively employ different correction methods, to correct the detected shake, so as to change the allocation of correction of the shake to the first correction unit and the second correction unit based on information regarding the acquired shutter speed,
• wherein the second correction unit employs an electronic shake correction method, and corrects the shake by changing a region that is to be extracted from an image signal acquired through image capturing, and
• the control is performed such that a movable area that can be used to extract the region from the image signal that is to be subjected to correction performed by the second correction unit is changed according to the shutter speed.
