Abstract

A display control device to control settings of a display is provided. The display control device comprises a photo sensor, a determining module and a controller. The photo sensor detects a user hand at different timings to generate a plurality of images. The determining module analyzes the images to generate a series of gesture signals for the user hand. The controller generates a control signal to display an on-screen display menu once activated, and to select options within the on-screen display menu and control the setting of the selected option based on the gesture signals such that the display can be adjusted accordingly.

Claims

1. A display control device to control settings of a display, wherein the display control device comprises:

a photo sensor to detect a user hand at different timings to generate a plurality of images;

a determining module to analyze the images to generate a series of gesture signals for the user hand; and

a controller to generate a control signal to display an on-screen display menu once activated, and to select options within the on-screen display menu and control the setting of the selected option based on the gesture signals such that the display can be adjusted accordingly.

2. The display control device of claim 1, further comprising a trigger to generate an activating signal in response to a user input, such that the display control device may be activated.

3. The display control device of claim 1, wherein the options of on-screen display menu are arranged in a first direction, and the selection of the options within the on-screen display menu is achieved by one or more gesture signals in the first direction, followed by another gesture signal in a second direction perpendicular to the first direction.

4. The display control device of claim 3, wherein the controller displays an adjustment bar once the selected option is confirmed, the controlling of the setting of the selected option is achieved by one or more gesture signals in the first direction, followed by another gesture signal in a second direction perpendicular to the first direction.

5. The display panel control device of claim 4, wherein the first direction is horizontal, and a second direction is vertical.

6. The display panel control device of claim 4, wherein the first direction is vertical, and a second direction is horizontal.

7. The display control device of claim 1, wherein the photo sensor is a CMOS sensor.

8. The display control device of claim 1, wherein the photo sensor is a CCD sensor.

9. The display control device of claim 1, further comprising an indicator confirming safe receipt of the gesture signals from the determining module.

10. The display control device of claim 9, wherein the indicator is a LED.

11. A display control method to control settings of a display, comprising:

displaying an on-screen display menu once activated;

detecting a user hand at different timings to generate a plurality of images;

analyzing the images to generate a series of gesture signals for the user hand; and

selecting options within the on-screen display menu and controlling the setting of the selected option based on the gesture signals such that the display can be adjusted accordingly.

12. The display control method of claim 11, further comprising lighting an indicator once confirming safe receipt of the gesture signals.

13. The display control method of claim 12, wherein the indicator is a LED.

14. The display control method of claim 11 is activated in response to a user input.

15. The display control method of claim 11, wherein the options of on-screen display menu are arranged in a first direction, and the selecting of the options within the on-screen display menu is achieved by one or more gesture signals in the first direction, followed by another gesture signal in a second direction perpendicular to the first direction.

16. The display control method of claim 15, further comprising displaying an adjustment bar once the selected option is confirmed, and the controlling of the setting of the selected option is achieved by one or more gesture signals in the first direction, followed by another gesture signal in a second direction perpendicular to the first direction.

17. The display control method of claim 16, wherein the first direction is horizontal, and a second direction is vertical.

18. The display control method of claim 16, wherein the first direction is vertical, and a second direction is horizontal.

19. The display control method of claim 11, wherein the detecting step is achieved by a CMOS sensor.

20. The display control method of claim 11, wherein the detecting step is achieved by a CCD sensor.
