Image capturing method and display method for recognizing a relationship among a plurality of images displayed on a display screen

A method for controlling an image capturing apparatus comprising an imager configured to acquire image data by capturing images including a first image and a second image, and a display configured to reproduce/display the images on a display screen based on the image data, the method comprising:

• acquiring first information including at least either an azimuth angle or an elevation angle as a photographing direction of each image and at least either an angle of view of the each image or angle-of-view related information for calculating the angle of view;
• and
• when a second photographing direction or a partial angle of view of the second image is included within a range of a first angle of view in a first photographing direction of the first image or within a range of a threshold angle of view extended out of the range of the first angle of view, controlling the display to reproduce/display (1) the first image or a first graphic indicating the first image selected based on a user operation on a background region corresponding to a predetermined range of angle of view within the display screen, and (2) the second image or a second graphic indicating the second image in a positional relationship corresponding to the second photographing direction,
• wherein the background region is a rectangular or circular region corresponding to a range of an angle of view that is equal to or more than 180° in a spherical face of a celestial sphere centered on the image capturing apparatus, and
• wherein the method further comprising, at a time of the reproducing/displaying, on the background region, controlling the display to reproduce/display, onto the spherical face, (1) a projection image of the first image, a shrunk first image thereof, or an enlarged first image thereof at a position corresponding to the first photographing direction of the first image, and (2) a projection image of the second image, a shrunk second image thereof, or an enlarged second image thereof at a position corresponding to the second photographing direction of the second image.
