Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
Embodiments providing a kind of display terminal image rotating method, the method is applied to base RCP's
Display control program, it is achieved firstly the need of building hardware configuration before the embodiment of the present invention, as it is shown in figure 1, should
Display control program includes display terminal 1, remote controller 2 and is built-in with the mobile terminal 3 of gravity sensor,
It is connected by high-definition audio and video standard interface (HML) between described display terminal 1 and mobile terminal 3, described
Remote controller 2 triggers the message described display terminal 1 of control by generating button, and concrete, display terminal 1 connects
Being transmitted to mobile terminal 3 after receiving the button triggering message that remote controller 2 sends, mobile terminal 3 is according to described
Button triggers message and performs respective operations, such as goes up page turning, lower page turning, return etc., the most described display
Terminal 1 demonstrates the display picture identical with described mobile terminal.In order to technical side of the present invention is described
Case, illustrates below by specific embodiment.

The interface of dynamic terminal achieves the rotation of image, such as turn left, turn right, upper upset, lower upset etc., specifically
The anglec of rotation relevant to described predetermined angle.As a kind of implementation, when described predetermined angle is according to respectively
For+90 ° ,-90 ° ,+180 ° ,-180 ° time, can correspondence realize image left-hand rotation, right-hand rotation, upper upset,
Lower upset.
Step S205, when described button trigger message be not rotate order time, perform described button trigger message
Corresponding operation.
When mobile terminal judges that current button triggering message is other action commands, perform this button and trigger
The operation that message is corresponding, such as page up, lower one page or return etc..
The present embodiment by using the current angular of gravity sensor perception and the difference of a predetermined angle as display
The foundation of image direction, system controls the display direction of image according to the angular range residing for this difference, by
It is necessarily in different angular ranges from described current angular, therefore at the interface of mobile terminal in described difference
On achieve image rotation.This method realizes simple, only just can be carried out on display terminal by remote controller
Image rotation.
