Abstract: A game apparatus is provided which has a convenience where another function, such as photo taken by a camera, can be used while playing a game by causing a game program and another program to work together. The game apparatus increases interest of the game by relating a result of execution of the other program to the contents of the game. For example, when a camera icon displayed on a display is selected by an operation of a touch panel, a program for controlling a camera function launches, and an image can be captured at an arbitrary timing. The captured image is converted according to a predetermined condition. The converted image is displayed on a display screen and image data is stored in a flash memory.
