<p><P>PROBLEM TO BE SOLVED: To provide a video game apparatus in which a burden for the generation processing of a scope image is reduced when generating the scope image by using a polygon. <P>SOLUTION: A background texture generation part 103 generates an image of the whole background (background texture) to a magnifying RAM 140 (by making the same resolution as that of the scope image). A display image display processing part 104 generates an image (display image) with a reduced background texture in the background plotting area of the RAM 11a. The background texture has a resolution higher than that of the display picture. Then, while an eyepiece sensor 35, or the like, is on, a scope image display processing part 106 sets a scope mark 1051 with the coordinates of spot beams at the generation of a trigger on signal as a center in the display image, extracts an image in a prescribed area with the spot beams as a center from the background texture, and pastes this extracted image in the scope mark 1051 by overwriting. <P>COPYRIGHT: (C)2004,JPO</p> |
