摘要

In order to sensually grasp, during operation, the direction in which one is trying to switch the viewpoint and/or aim on a display device, even if the purpose is, for example, to knock down an opponent, a program execution device includes an aim/viewpoint selection means or function, which judges whether the operation input from the user is a viewpoint switching instruction or an aim switching instruction, a viewpoint switching processing means or function, which performs viewpoint switching processing if the result of the judgment in the aim/viewpoint selection means is that it is a viewpoint switching instruction, and an aim switching processing means, to perform aim switching processing if the result of the judgment in the aim/viewpoint selection means is that it is an aim switching instruction. An image display processing means of the program execution device is used to output to a monitor image data, drawn to an image memory (RAM) after having gone through processing by the viewpoint switching processing means or the aim switching processing means, and to display the image data on a screen of the monitor.
