<P>PROBLEM TO BE SOLVED: To provide a device and a method for performing effective display control even when the device exceeds a prescribed operation range, in constitution in which switching of display data by rotation-operation of a device is performed. <P>SOLUTION: In constitution in which update processing of display data is executed based on rotary angle information of a device detected by a sensor, when the device is rotated exceeding the operation range already set to the device, a control part changes the operation range. Specifically, the operation range is updated successively so that the present angle of the image display device is always set within the operation range. By update processing of the operation range, the device is always set to the effective operation range, such a problem that display data is fixed by a device position is caused, and display data can be always updated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
