Abstract

There is provided a method for detecting a rotation angle of a remote controller(21) in a television system(30,40) in order to realize a detection for the rotation angle of the remote controller(21) with respect to the television(20), which extends an application prospect of the television system. The television system (30,40) includes a television (20) and a remote controller (21), and the method comprises: collecting(S101), by the remote controller (21), an image of preset infrared sensors on the television (20) and imaging the collected image to a preset plane as a standard image, in a case in which the remote controller(21) does not rotate with respect to the television(20); collecting(S102), by the remote controller(21), an image of the infrared sensors on the television(20) and imaging the collected image to the preset plane again, in a case in which the remote controller(21) rotates with respect to the television(20); and calculating(S103) a rotation angle in a case in which the remote controller(21) rotates with respect to a screen of the television(20) by comparing the image with the standard image. There is further provided a television system(30,40).

Claims

1. A method for detecting a rotation angle of a remote controller in a television system including a television and the remote controller, wherein the method comprises:

collecting, by the remote controller, an image of preset infrared sensors on the television and imaging the collected image to a preset plane as a standard image, in a case in which the remote controller does not rotate with respect to the television;

collecting, by the remote controller, an image of the infrared sensors on the television and imaging the collected image to the preset plane again, in a case in which the remote controller rotates with respect to the television; and

calculating a rotation angle in a case in which the remote controller rotates with respect to a screen of the television by comparing the image with the standard image.

2. The method of claim 1, wherein the remote controller transmits the imaged image to the television, the television compares the image with the standard image and calculates the rotation angle in a case in which the remote controller rotates with respect to the screen of the television.

3. The method of claim 1, wherein the remote controller compares the image with the standard image and calculates the rotation angle in a case in which the remote controller rotates with respect to the screen of the television.

4. The method of claim 3, wherein the method further comprises:

transmitting, by the remote controller, the obtained rotation angle to the television.

5. The method of claim 1, wherein the preset infrared sensors on the television comprise:

infrared sensors disposed at corners of a diagonal of a light-guide plate (LGP) in the television and on a side without a light bar;

or

infrared sensors disposed at corners of a light bar and along a diagonal of the LGP in the television;

or

infrared sensors disposed at corners on a shell of the television corresponding to corners of a display screen.

6. The method of claim 5, wherein the number of the infrared sensors, disposed at the corners of the diagonal of the LGP in the television and on the side without the light bar or disposed at the corners of the light bar and along the diagonal of the LGP in the television, is two.

7. The method of claim 5, wherein the number of the infrared sensors, disposed at corners on the shell of the television corresponding to the corners of the display screen, is two, three or four.

20. The method of claim 1, wherein the infrared sensors generate right-angle spots.

8. A television system including a television and a remote controller, wherein,

the remote controller comprises:

13. The television system of claim 8, wherein the infrared sensors are infrared light emitting diodes (LEDs).

14. A television system including a television and a remote controller, wherein,

the remote controller comprises:

an image collection unit configured to collect an image of preset infrared sensors on the television and image the collected image to a preset plane as a standard image, in a case in which the remote controller does not rotate with respect to the television; and

to collect an image of the infrared sensors on the television and image the collected image to the preset plane again, in a case in which the remote controller rotates with respect to the television;

a calculation unit configured to calculate a rotation angle in a case in which the remote controller rotates with respect to a screen of the television by comparing the image with the standard image; and

a transmitting unit configured to transmit the rotation angle calculated by the calculation unit to the television,

the television comprises;

a receiving unit configured to receive the rotation angle transmitted from the transmitting unit of the remote controller.

15. The television system of claim 14, wherein the infrared sensors are located at corners of a diagonal of a light-guide plate LGP in the television and on a side without a light bar;

or located at corners of a light bar and along a diagonal of the LGP in the television;

or located at corners on a shell of the television corresponding to corners of a display screen.

16. The television system of claim 15, wherein the number of the infrared sensors, disposed at the corners of the diagonal of the LGP in the television and on the side without the light bar or disposed at the corners of the light bar and along the diagonal of the LGP in the television, is two.
