Abstract:
1. An information display device that displays application screens for a plurality of types of applications individually, said information display device comprising: storage means for storing information related to a display for each application; judgment means for judging a display direction for each application screen; detection means for detecting a preset method from among a plurality of methods for deciding a reference for a display control when the judgment means judges that the display direction for the application screens differs from each other; selection means for selecting one of the plurality of types of applications as a reference for the display control according to the preset method detected by the detection means and the information related to the display for each application stored by the storage means; display control means for performing the display control to orient a display direction of an application that has not been selected as the reference for the display control to a display direction of an application that has been selected as the reference for the display control by the selection means; and changing means for changing the display direction of any application among the plurality of types of applications, wherein the judgment means performs the judging of a display direction when the display direction of any application is changed by the changing means while application screens of a plurality of already running applications are being displayed simultaneously, wherein the plurality of types of applications comprise a vertically long application screen configuration with an uneven aspect ratio or a horizontally long application screen configuration with an uneven aspect ratio which have been designed in advance, wherein the changing means changes a screen configuration of an application whose display direction is changed such that, when an aspect ratio of the screen configuration before the display direction is changed differs from an aspect ratio of the screen configuration after the display direction is changed, the screen configuration accords with the aspect ratio after the display direction is changed, and wherein, when an application whose display direction is changed is devoid of a screen configuration that accords with the aspect ratio after the display direction is changed, the changing means reduces a size of the overall screen configuration before the display direction is changed and then rotates a reduced screen configuration to the display direction that is changed.
