Abstract: When a game operation image is displayed on a touch panel of a portable terminal, the size of a game display screen and the operation image are small and therefore the progress of a game becomes difficult. Even in the case of a terminal having only a touch panel of a limited size, an operation image having a size that affects the progress of a game as little as possible is displayed on the touch panel by superimposing the operation image on a game display screen at a position that affects the progress of the game as little as possible.
