Abstract

A method for switching to display three-dimensional (3D) images and a digital display system are provided. In the method, a digital display is activated to receive image data comprising at least one image and to detect a triggering signal, which is generated by detecting whether a 3D glasses is being used through a software means or a hardware means. According to the triggering signal, the digital display switches between formats of two-dimensional (2D) image and 3D image, so as to display the images.

Claims

1. A method for switching to display three-dimensional (3D) images, comprising:

activating a digital display to receive image data comprising at least one image;

detecting a triggering signal; and

switching between formats of two-dimensional (2D) image and 3D image according to the triggering signal so as to display at least one image in the image data.

2. The method according to claim 1, wherein the step of detecting the triggering signal comprises:

detecting whether a 3D glasses is being used; and

generating the triggering signal when the 3D glasses is detected as being used.

3. The method according to claim 2, wherein the step of detecting whether the 3D glasses is being used comprises:

detecting whether the 3D glasses is worn by a user by using a sensor disposed on the 3D glasses.

4. The method according to claim 3, wherein the sensor is disposed on a nose pad portion, an ear hanger portion, or a glass clip portion of the 3D glasses, so as to detect whether the 3D glasses is worn by the user.

5. The method according to claim 2, wherein the step of detecting whether the 3D glasses is being used comprises:

detecting whether the 3D glasses is taken by a user by using a G-sensor disposed on the 3D glasses.

6. The method according to claim 2, wherein the step of detecting whether the 3D glasses is being used comprises:

detecting whether the 3D glasses is taken by a user by using a switch disposed on a holder for placing the 3D glasses.

7. The method according to claim 1, wherein the step of detecting whether the 3D glasses is being used comprises:

capturing a user image;

recognizing a face image in the user image by using a human face recognition algorithm; and

detecting whether the face image comprises the 3D glasses, so as to determine whether the 3D glasses is being used.

8. The method according to claim 1, wherein the step of switching to display the at least one image between the formats of 2D image and 3D image according to the triggering signal comprises:

switching the format of the at least one image to the 3D image for display when receiving the triggering signal; and

switching the format of the at least one image to the 2D image for display when no triggering signal is received.

9. The method according to claim 8, wherein the step of switching the format of the at least one image to the 3D image for display comprises:

determining the format of the at least one image is the 2D image or the 3D image;

transforming the format of the at least one image to the 3D image and displaying the transformed images if the format of the at least one image is the 2D image; and

directly displaying the at least one image if the format of the at least one image is the 3D image.

10. The method according to claim 9, wherein the step of transforming the format of the at least one image to the 3D image and displaying the transformed image comprises:

dividing each of the at least one image to a left eye image and a right eye image; and

simultaneously displaying the divided left eye image and right eye image.

11. The method according to claim 8, wherein the step of switching the format of the at least one image to the 2D image for display comprises:

determining the format of the received at least one image is the 2D image or the 3D image;

directly displaying the at least one image if the format of the at least one image is the 2D image; and

transforming the format of the at least one image to the 2D image and displaying the transformed images if the format of the at least one image is the 3D image.

12. A digital display system, comprising:

a detection device, for detecting whether a 3D glasses is being used and generating a triggering signal accordingly; and

a digital display, for receiving image data and switching between formats of 2D image and 3D image according to the triggering signal so as to display at least one image in the image data.

13. The system according to claim 12, wherein the detection device comprises:

a sensor, disposed on the 3D glasses, for detecting whether the 3D glasses is being used.

14. The system according to claim 13, wherein the sensor is disposed on a nose pad portion, an ear hanger portion, or a glass clip portion of the 3D glasses, so as to detect whether the 3D glasses is worn by a user.

15. The system according to claim 13, wherein the sensor is a G-sensor disposed on the 3D glasses, so as to detect whether the 3D glasses is being taken by a user.

16. The system according to claim 13, wherein the detection device comprises:

a transmitter, for transmitting the triggering signal to the digital display through a wireless means when the sensor detects the 3D glasses is being used, so as to control the digital display to switch to display the at least one image.

17. The system according to claim 12, wherein the detection device comprises:

a switch, disposed on a holder of the 3D glasses for determining whether the 3D glasses is being taken by a user.

18. The system according to claim 12, wherein the detection device comprises:

an image capturing unit, for capturing a user image;

a face recognition unit, for recognizing a face image in the user image by using a human face recognition algorithm; and

a characteristic identifying unit, for detecting whether the face image comprises the 3D glasses, so as to determine whether the 3D glasses is being used.

19. The system according to claim 12, wherein the digital display comprises:

switching the format of the at least one image to the 3D image for display when receiving the triggering signal; and

switching the format of the at least one image to the 2D image for display when no triggering signal is received.

20. The system according to claim 19, wherein the digital display comprises:

a transformation unit, for transforming the format of the at least one image from the 2D image to the 3D image, or from the 3D image to the 2D image for display.
