PROBLEM TO BE SOLVED: To constantly retain the apparent size of objects actually displayed on a two-dimensional image despite of a distance from the point of view in a virtual three-dimensional space. SOLUTION: This image generator for developing objects arranged in the virtual three-dimensional space on a two-dimensional plane to generate a two-dimensional image is provided with: an object data storage part 4041 for storing data of symbol objects displayed in a same size constantly on the two-dimensional image; an object arrangement part 4043 for arranging the symbol objects in the virtual three-dimensional space; an object size change part 4042, when a distance of a symbol object from the point of view is changed in the virtual three-dimensional space, changing the size of the symbol object in proportion to the change in the distance; and a rendering part 4044 executing a perspective projection arithmetic processing where the farther a distance becomes from the point of view, the smaller the object is developed on the two-dimensional plane.
