A menu screen creator creates on a default background image a menu screen in which the first icon and another icon image are arranged. When an input receiving unit receives operation information indicating an operation for selecting the first icon image is performed, a background image processor directs the menu screen creator to switch the default background image to a first background image acquired from the recording medium.
