• an acquisition unit configured to acquire information about a subject detected from a captured image;
• a calculation unit configured to calculate a tracking amount based on a position of the subject in the captured image and a target position;
• a control unit configured to control subject tracking to bring the position of the subject in the captured image close to the target position, based on the tracking amount;
• and
• a setting unit configured to set a first region and a second region based on at least any of a holding state of an imaging apparatus that captures the captured image, a detection result of an operation performed by a photographer on the imaging apparatus, a position in the captured image of the target position, and a type of the subject,
• wherein, in the first region, a degree to which the subject tracking is performed is lower than in the second region.
