<p>Disclosed are an apparatus and method for effective display control even when an apparatus exceeds a prescribed operating range, in a configuration that switches display data according to apparatus rotation operations. A control unit changes the operating range when the apparatus rotates beyond the operating range preset on the apparatus, in a configuration that updates display data based on apparatus rotation angle information that is detected by a sensor. Specifically, the operating range is sequentially updated so that the present angle of an image display apparatus is constantly set within the operating range. With this operating range updating process, the apparatus is constantly set to the effective operating range, and display data is constantly updated without a problem of the display data becoming fixed by the apparatus position.</p> |
