Zooming control apparatus, image capturing apparatus and control methods thereof

A zooming control apparatus comprising:

• an object detection unit configured to detect an object from an image acquired through an imaging optical system;
• a first acquisition unit configured to acquire information regarding a distance to the object;
• and
• a zooming control unit configured to perform one of a first zooming control for automatically changing a zoom magnification according to first information that includes information regarding a size of the object detected by the object detection unit and a second zooming control, that is different from the first zooming control, for automatically changing a zoom magnification according to second information regarding the distance to the object acquired by the first acquisition unit,
• wherein the zooming control unit determines whether to perform the first zooming control or the second zooming control based on a relationship between a position of a focus lens included in the imaging optical system and a focal length of the imaging optical system.

A control method of a zooming control apparatus comprising:

• detecting an object from an image acquired through an imaging optical system;
• acquiring information regarding a distance to the object;
• determining whether to perform one of the first zooming control and the second zooming control that is different from the first zooming control in accordance with a focus state of the imaging optical system;
• and
• performing a zooming control for automatically changing a zoom magnification based on the determination,
• wherein the first zooming control automatically changes a zoom magnification according to first information that includes information regarding a size of the detected object, and the second zooming control automatically changes a zoom magnification according to second information regarding the distance to the object.
