PROBLEM TO BE SOLVED: To make limitable the discontinuation between a two-dimensional image and its peripheral world in a three-dimensional virtual reality world by distorting a two-dimensional perspective image for the purpose of moving a partial disappearing point of the two-dimensional perspective image based on the current visual point of a user. SOLUTION: A display structure called 'pyramid panel structure' is used to display a peripheral CG(computer graphics) part 120 of a two-dimensional image 115 within a three-dimensional space so as to make a screen or a panel 110 cope with the change of a visual point. The conversion concerning the pyramid panel structure is dynamically distorted according to the position of a person who is looking at the image 115, and the disappearing point of the image concerning the movement of the image looking person is adjusted. Thus, such distortion limits the discontinuation between the image 115 and the part 120 as the image looking person moves from an ideal visual point of the image 115. That is, a two-dimensional perspective image is distorted in order to move a partial disappearing point of the two-dimensional perspective image according to the current visual point of a user. |
