Image display apparatus and method
First Claim
1. An apparatus for displaying an image, comprising:
- an image display unit including a display region having a higher resolution than a number of pixels of the image;
a base information storage unit configured to store viewing position information of a viewer, and size information of the display region; and
a wide-angle transformation unit configured to calculate a central area including a viewing center of the viewer of the display region using the viewing position information and the size information, to divide the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area, and to transform the first pixel area and the second pixel area by magnifying, a magnification ratio of the first pixel area being less than a magnification ratio of the second pixel area;
wherein the image display unit displays an image including the transformed first pixel area and the transformed second pixel area.

Abstract
An image display unit has a display region with a higher resolution than a number of pixels of an image. A base information storage unit stores viewing position information of a viewer and size information of the display region. A wide-angle transformation unit calculates a central area including a viewing center of the viewer of the display region using the viewing position information and the size information, divides the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area, and transforms the first pixel area and the second pixel area by magnifying. A magnification ratio of the first pixel area is less than a magnification ratio of the second pixel area. The image display unit displays an image including the transformed first pixel area and the transformed second pixel area.

19. A method for displaying an image on a display region having a higher resolution than a number of pixels of the image, comprising:
-
storing viewing position information of a viewer, and size information of the display region; calculating a central area including a viewing center of the viewer of the display region using the viewing position information and the size information; dividing the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area; transforming the first pixel area and the second pixel area by magnifying, a magnification ratio of the first pixel area being less than a magnification ratio of the second pixel area; and displaying an image including the transformed first pixel area and the transformed second pixel area.

20. A computer readable medium that stores a computer program for causing a computer to display an image on a display region having a higher resolution than a number of pixels of the image, the computer program comprising:
-
a first program code to store viewing position information of a viewer, and size information of the display region; a second program code to calculate a central area including a viewing center of the viewer of the display region using the viewing position information and the size information; a third program code to divide the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area; a fourth program code to transform the first pixel area and the second pixel area by magnifying, a magnification ratio of the first pixel area being less than a magnification ratio of the second pixel area; and a fifth program code to display an image including the transformed first pixel area and the transformed second pixel area.
