Image display apparatus, image display method, and computer-readable storage medium

Abstract

An image display apparatus according to an embodiment of the present invention includes: a moving unit configured to move a display position of an image displayed on a display screen; a setting unit configured to set a compressed image display area on the display screen; and a compression unit configured to, in a case where the display position of the image is moved by the moving unit, compress a part of the image extending off the display screen and a part of the image displayed in the compressed image display area so that these parts fit within the compressed image display area, and to display a compressed image in the compressed image display area on the display screen.

1 . An image display apparatus comprising:
 a moving unit configured to move a display position of an image displayed on a display screen;   a setting unit configured to set a compressed image display area on the display screen; and   a compression unit configured to, in a case where the display position of the image is moved by the moving unit, compress a part of the image extending off the display screen and a part of the image displayed in the compressed image display area so that these parts fit within the compressed image display area, and to display a compressed image in the compressed image display area on the display screen.   
   
   
       2 . The image display apparatus according to  claim 1 , wherein, assuming that a length of the compressed image display area in a moving direction of the display position of the image is Lc and a moving distance of the display position of the image is Lm, the compression unit compresses an image to be displayed in the compressed image display area at a compression ratio of Lc/(Lc+Lm). 
   
   
       3 . The image display apparatus according to  claim 1 , wherein the setting unit sets the compressed image display area on a basis of an amount of movement of the display position of the image moved by the moving unit. 
   
   
       4 . An image display method for an image display apparatus comprising:
 moving a display position of an image displayed on a display screen;   setting a compressed image display area on the display screen; and   compressing, in a case where the display position of the image is moved, a part of the image extending off the display screen and a part of the image displayed in the compressed image display area so that these parts fit within the compressed image display area, and displaying a compressed image in the compressed image display area on the display screen.   
   
   
       5 . A computer-readable storage medium storing computer-executable instructions for:
 moving a display position of an image displayed on a display screen;   setting a compressed image display area on the display screen; and   compressing, in a case where the display position of the image is moved, a part of the image extending off the display screen and a part of the image displayed in the compressed image display area so that these parts fit within the compressed image display area, and displaying a compressed image in the compressed image display area on the display screen.
