Abstract: An image processor is composed of a game device body, an operation panel and a display. The game device body is composed of a data processor 12 and a memory 12. The data processor realizes a hit determining circuit 112, an enemy control circuit 112, an enemy (object) set circuit 114, a cursor control circuit 114, an enemy retrieval circuit 116 and a camera control circuit 116 in accordance with corresponding programs used. When an object is displayed on the display, the cursor control circuit displays a cursor in accordance with predetermined processing performed on the basis of data on the coordinates of the object. The camera control circuit 116 performs a zoom-in display process for the object when the object is displayed on the display.

Abstract: A light trace expressing a trace generated in a case where a light source is moved in a virtual three-dimensional space can be displayed with higher reality. An initially used table or the like is initialized. Next, a light source or the like is moved by an operation input or the like. Subsequently, perspective transformation is carried out to obtain a position of the light source on a display screen. Next, a polygon having a predetermined width is generated along a new movement locus of the light source on the display screen. Then, transparency of all the generated polygons is raised. In the polygon generated earlier, the transparency increases. Then, a texture in which the brightness is high along the movement locus of the light source and the brightness of a position decreases as the position departs from the movement locus, is mapped to the polygon. Thereafter, &agr; blending is used to draw the polygon on the movement locus of the light source. The drawn image is displayed on the display screen.
