    Patent number: 6676518
    Abstract: A game progress control device administers positions of player characters and a referee using positions corresponding to their waists. A shadow image generating device generates shadow images of all the player characters and the referee character who appear on the screen of the monitor. A density setting device sets the density of each shadow based image based on the position of the appearing character on a soccer field using an x-coordinate of his waist. Accordingly, the shadow images of specified densities belonging to the individual appearing characters can be generated by simple calculation.
