An imaging apparatus comprising: an imaging unit for successively capturing images of a subject in a live-view; a change detection unit for detecting a change between the images successively captured by the imaging unit; an angle of view change determination unit for determining a direction of change of an angle of view between the images on the basis of the change between the images detected by the change detection unit; a subject detection unit for detecting a region as the subject region corresponding to a subject, on the basis of a difference between the change of angle of view between the images determined by the angle of view change determination unit and the change between the images detected by the change detection unit; a determination unit for determining a moving state of the subject and a moving state of the imaging unit that captures the image of the subject in the moving state on the basis of the change in the angle of view between the images and the change between images detected by the change detection unit; a specification unit for specifying as the subject region corresponding to a subject that should be tracked an image region matching above a predetermined threshold value a template image detected from the image captured by the imaging unit in advance; and a control unit for controlling tracking of the subject region included in the image captured by the imaging unit on the basis of determination results from the determination unit by changing a range where the subject region should be tracked in the image and by changing the predetermined threshold value on the basis of the determination results from the determination unit. an imaging unit for successively capturing images of a subject in a live-view; a change detection unit for detecting a change between the images successively captured by the imaging unit; an angle of view change determination unit for determining a direction of change of an angle of view between the images on the basis of the change between the images detected by the change detection unit; a subject detection unit for detecting a region as the subject region corresponding to a subject, on the basis of a difference between the change of angle of view between the images determined by the angle of view change determination unit and the change between the images detected by the change detection unit; a determination unit for determining a moving state of the subject and a moving state of the imaging unit that captures the image of the subject in the moving state on the basis of the change in the angle of view between the images and the change between images detected by the change detection unit; a specification unit for specifying as the subject region corresponding to a subject that should be tracked an image region matching above a predetermined threshold value a template image detected from the image captured by the imaging unit in advance; and a control unit for controlling tracking of the subject region included in the image captured by the imaging unit on the basis of determination results from the determination unit by changing a range where the subject region should be tracked in the image and by changing the predetermined threshold value on the basis of the determination results from the determination unit.
