GAME DEVICE AND METHOD FOR FORMING IMAGE DATA AND MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a video game device for expressing the trace of an object moving in a video game on a screen. SOLUTION: A game device for displaying an object moving according to the development of a game as an image is provided with a means S132 for reading the present position of the object and a trace mark plotting means S132-S158 for plotting a trace mark with a length within a prescribed range from the present position, and for gradually making faint and extinguishing the rear edge side of the trace mark according to the lapse of a time. Thus, arithmetic amounts of the image processing can be reduced by reducing a trace polygon such as a tire.
