<p><P>PROBLEM TO BE SOLVED: To provide an image-synthesizing device which deletes the display of an object with simple processing and obtains a real image by deleting the object gradually from one direction. <P>SOLUTION: When a three-dimensional object 410 representing an enemy fighter or the like enters behind a three-dimensional object 400 composed of transparent polygons 402, part of the three-dimensional object 410 is hidden by the three-dimensional object 400. The transparent polygons 402 constituting the three-dimensional object 400 allow a background image to pass through when they synthesize an image together with the background image. Accordingly, the three-dimensional object 410 such as the enemy fighter or the like entering behind the three-dimensional object 400 disappears from a display screen as if the above object 410 enters at the back of a prop 420 by preparing the three-dimensional object 400 which has nearly the same shape as the prop 420 included in the background image and is formed at a position where it almost covers the prop 420. <P>COPYRIGHT: (C)2004,JPO</p> |
