Abstract: An image processing device which places a display object within a virtually-defined three-dimensional space, creates a picture of the display object viewed from a virtual viewpoint with the image processing device, and displays the picture on a display. The image processing device comprises a display body setting element for setting a plurality of display bodies within said three-dimensional space; a display body disposal element for overlappingly disposing one of the plurality of display bodies within the display object, a display body image setting element for setting an image of the display object such that the one of the plurality of display bodies housed within the display object becomes visible, and a display body movement mode reflection element for making at least one movement mode of the one of the plurality of display bodies reflect a movement mode of the display object.

Abstract: A text 220, which needs to be displayed constantly, is displayed on the floor/wall 206C in the background image 202. This text (number) 220, as shown in FIG. 5, is structured of an aggregate of a plurality of plate polygons 222. Each of these plate polygons can be subject to gradation in accordance with the camera viewpoint, and, as a result, is displayed in a state of being three-dimensional with concavities and convexities against the floor/wall 206C as illustrated in FIG. 4. These plate polygons 222 cannot become the counterstroke face of the ball 212, and the floor/wall 206C is judged as a plane.
