Image display system, terminal, method, and program for determining a difference between a first image and a second image

An image display method comprising:

• acquiring a first image captured by a mobile terminal;
• acquiring information including a first position and a first orientation of the mobile terminal that has captured the first image;
• acquiring a second image based on the first position and the first orientation;
• acquiring a second position and a second orientation associated with the second image stored in a storage device, the second image being a panoramic image including an image captured with an angle range wider than a captured range of the first image and being captured within a predetermined distance from a current position of the mobile terminal;
• selecting a part cut out from the second image in a direction corresponding to the first orientation;
• and
• displaying the part cut out from the second image.

A non-transitory computer-readable storage medium storing a program that causes a computer to perform:

• acquiring a first image captured by a mobile terminal;
• acquiring information including a first position and a first orientation of the mobile terminal that has captured the first image;
• acquiring a second image based on the first position and the first orientation;
• acquiring a second position and a second orientation associated with the second image stored in a storage device, the second image being a panoramic image including an image captured with an angle range wider than a captured range of the first image and being captured within a predetermined distance from a current position of the mobile terminal;
• selecting a part cut out from the second image in a direction corresponding to the first orientation;
• and
• displaying the part cut out from the second image.
