<p>PROBLEM TO BE SOLVED: To provide a three-dimensional game device in which a player can effectively prevent the position of a target from being lost, and an image synthesizing method. SOLUTION: When the target 20 does not exist within a display area, a marker 30 showing the existence direction of the target 20 is displayed at a position corresponding to the existence direction of the target 20 in a peripheral part of a screen. Thus, the existence direction of the target 20 can easily be grasped and the player can effectively prevent the position of the target from being lost.</p> |
