PROBLEM TO BE SOLVED: To minimize an error by the effect of perspective transformation in formation of a perspective transformed image. SOLUTION: An image computing part 3 assigns, based on the polygon division number of a virtual plane polygon object, a texture coordinate with a correction object image as a texture, to each first polygon apex coordinate according to the polygon division number of the virtual plane polygon object, generates a non-plane screen as a screen polygon object on a three-dimensional space based on the shape and dimension of the non-plane screen, transforms each first polygon apex coordinate to a second polygon apex coordinate of the screen polygon object, transforms each second polygon apex coordinate to a corresponding third polygon apex coordinate on the same plane as the virtual plane polygon object, based on the position, projecting direction and field angle of the image display device 10, and perspectively transforms the third polygon apex coordinate.
