PROBLEM TO BE SOLVED: To provide a game machine capable of effectively partially displaying individual images while suppressing the increase of the memory capacity to some extent. SOLUTION: Image data are stored in a memory module 133 in association with a plurality of objects and still images. A VDP 135 performs the geometry operation including processing of disposing image data to a world coordinate system based on a picture drawing command from a display CPU 131, and creates picture drawing data as two-dimensional data by a rendering process including projection to a projecting plane. In the projection to the projecting plane, a masking process utilizing a Z buffer 143 is executed. In this case, a prescribed character is masked as a Z value of part of the object is set at a Z value in the back of the most posterior image. COPYRIGHT: (C)2011,JPO&INPIT
