3D display method and electronic device using the same

1 . A 3D display method, comprising:

detecting whether a pattern is in a video, wherein the video includes a plurality of frames, part of each of the frames is replaced by the pattern and the pattern is embedded in each of the frames;

determining whether the video has side-by-side content according to the pattern which replaces part of each of the frames and is embedded in each of the frames; and

presenting the side-by-side content, if the video has the side-by-side content.

2 . The 3D display method according to claim 1 , wherein the pattern includes a plurality of color blocks.

3 . The 3D display method according to claim 1 , wherein the pattern includes a plurality of black blocks and a plurality of white blocks.

4 . The 3D display method according to claim 1 , wherein the pattern is disposed at an edge area of each of the frames.

5 . The 3D display method according to claim 1 , wherein the pattern is disposed at an identical location in the frames of the video.

6 . The 3D display method according to claim 1 , wherein the pattern is a strip.

7 . The 3D display method according to claim 1 , wherein the pattern is a matrix.

8 . The 3D display method according to claim 1 , further comprising:

obtaining the frames from the video;

performing a depth estimation according to the frames to obtain a depth information; and

generating the side-by-side content according to the depth information.

9 . The 3D display method according to claim 1 , further comprising:

determining whether a demo mode is active; and

performing a user setting, if the demo mode is not active.

10 . The 3D display method according to claim 1 , further comprising:

determining whether a demo mode is activate; and

disabling a user command, if the demo mode is activate.

11 . An electronic device, comprising:

a display unit, configured to display a video;

a pattern detection unit, configured to detect whether a pattern is in the video, wherein the video includes a plurality of frames, part of each of the frames is replaced by the pattern and the pattern is embedded in each of the frames; and
