PROBLEM TO BE SOLVED: To reduce arithmetic load without reducing expressiveness for audiences or the like in an image processing technique for further realistically expressing a number of audiences in a game device with a sport theme or the like while reducing the arithmetic load. SOLUTION: The program makes a computer function as (a) a means for arranging a model formed by crossing a plurality of sheet-like polygons (PG1, PG2 and PG3) in a virtual three-dimensional space; (b) a means for computing a parameter depending on an angle between a first vector V1 set in association with the model and a second vector V3 set in association with the visual line direction of a virtual camera; (c) a means for selecting one of the plurality of sheet-like polygons constituting the model as a display object according to the parameter; (d) a means for mapping the selected sheet-like polygon with a predetermined texture; and (e) an image generation means for generating a two-dimensional image obtained by perspectively projecting the inside of the virtual three-dimensional space in which the model mapped with the texture is arranged onto a perspective projection plane set in conformation to the visual point of the virtual camera.
