Control apparatus and method, image stabilization apparatus, image capturing apparatus, and storage medium

A control apparatus that controls a first image stabilization unit that performs optical image stabilization and a second image stabilization unit that performs image stabilization by changing a crop position of a partial image cropped from an image captured by an image sensor, the apparatus comprising one or more processors and/or circuitry which function as:

• a first acquisition unit that acquires a shake amount representing a magnitude of shake of a detection target;
• a second acquisition unit that acquires a tracking amount for keeping a predetermined subject included in the image at a predetermined position in the partial image;
• a third acquisition unit that acquires a first value indicating a degree of allocating the first image stabilization unit to image stabilization and a second value indicating a degree of allocating the first image stabilization unit to tracking control, a third value indicating a degree of allocating the second image stabilization unit to the image stabilization, and a fourth value indicating a degree of allocating the second image stabilization unit to the tracking control;
• and
• a fourth acquisition unit that acquires control amounts of the first image stabilization unit and control amounts of the second image stabilization unit for the image stabilization and the tracking control based on the shake amount, the tracking amount, and the first to fourth values.

A control method for controlling a first image stabilization unit that performs optical image stabilization and a second image stabilization unit that performs image stabilization by changing a crop position of a partial image cropped from an image captured by an image sensor, the method comprising:

• a first acquisition step of acquiring a shake amount representing a magnitude of shake of a detection target;
• a second acquisition step of acquiring a tracking amount for keeping a predetermined subject included in the image at a predetermined position in the partial image;
• a third acquisition step of acquiring a first ratio for allocating a movable area of the first image stabilization unit to image stabilization and a second ratio for allocating the movable area of the first image stabilization unit to tracking control, a third ratio for allocating a movable area of the partial image of the second image stabilization unit to the image stabilization, and a fourth ratio for allocating the movable area of the partial image to the tracking control;
• and
• a fourth acquisition step of acquiring control amounts of the first image stabilization unit and control amounts of the second image stabilization unit for the image stabilization and the tracking control based on the shake amount, the tracking amount, and the first to fourth ratios.

A non-transitory computer-readable storage medium, the storage medium storing a program that is executable by the computer, wherein the program includes program code for causing the computer to function as a control apparatus that controls a first image stabilization unit that performs optical image stabilization and a second image stabilization unit that performs image stabilization by changing a crop position of a partial image cropped from an image captured by an image sensor, the apparatus comprising:

• a first acquisition unit that acquires a shake amount representing a magnitude of shake of a detection target;
• a second acquisition unit that acquires a tracking amount for keeping a predetermined subject included in the image at a predetermined position in the partial image;
• a third acquisition unit that acquires a first ratio for allocating a movable area of the first image stabilization unit to image stabilization and a second ratio for allocating the movable area of the first image stabilization unit to tracking control, a third ratio for allocating a movable area of the partial image of the second image stabilization unit to the image stabilization, and a fourth ratio for allocating the movable area of the partial image to the tracking control;
• and
• a fourth acquisition unit that acquires control amounts of the first image stabilization unit and control amounts of the second image stabilization unit for the image stabilization and the tracking control based on the shake amount, the tracking amount, and the first to fourth ratios.
