An image capture apparatus capable of eliminating wasteful photographing in predetermined panoramic photography. Predetermined panoramic photography combines images acquired by repeating still image capturing with long time-exposure and panning. A first angle of view in panning direction indicates an angle from a start to an end point in the photography. A photographing condition is calculated based on the first angle and a focal length of a photographic lens, and displayed changeable by a user. When combining the images, geometric deformation processing is performed thereon for changing a second angle of view indicative of an angle of view in a direction orthogonal to the panning direction according to the focal length. The second angle changed by the processing is calculated according to the set first angle and the displayed photographing condition. The second angle is displayed before and after the change.
