摘要：PROBLEM TO BE SOLVED: To provide an image display device, an image display method, an information storage medium and an image display program for reducing the distortion of individual polygon shapes when the image of a three-dimensional object constituted of polygons is displayed on a curved surface screen. SOLUTION: A division number decision part 41 decides a division number corresponding to the size of the individual polygons constituting the three- dimensional object, and a polygon division part 42 divides the individual polygons by the decided division number. A coordinate transformation processing part 43 calculates the storage position of a circular frame buffer 50 corresponding to the vertex coordinates of the respective divided polygons. Thereafter, a texture mapping processing part 44 generates image information with the inside of the individual divided polygon as a plotting area.
