Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] In the embodiment of the present invention, an automatic adjustment algorithm is used to adjust the timer period of the 3D glasses to match the period of the display terminal, which is described in detail as follows.

[0023] like figure 1 Shown is the flow chart of the display terminal of the embodiment of the present invention, and the specific steps are:

[0024] Step 11: Initialize;

[0025] Step 12: Enable interrupt;

[0026] Step 13: Wait for a video frame switching interrupt to be generated;

[0027] Step 14: After the video frame switching interrupt is generated, the number of interrupts is increased by 1; ...

Abstract

The invention discloses an automatic calibration shutter type 3D glasses synchronization method. The method comprises the following steps that: when there is no synchronization signal, a timing mode is adopted in the shutter type 3D glasses to carry out a lens state switching in every video frame period; a display terminal sends a synchronization signal during left and right eye video frame switching every several periods; after the shutter type 3D glasses receives the synchronization signal, a lens switching time is adjusted so as to align a video frame switching waveform of the display terminal and simultaneously an automatic calibration algorithm is executed to adjust a timer period of the shutter type 3D glasses so as to match the period of the display terminal. By using the invention, a complete synchronization between the shutter type 3D glasses and the display terminal can be realized; crosstalk phenomenon, such as obscuring, double image and the like, can be eliminated; good 3D display effects can be reached.

Description

technical field [0001] The invention relates to the technical field of 3D glasses, in particular to an automatic calibration shutter type 3D glasses synchronization method. Background technique [0002] The shutter-type 3D glasses can produce a three-dimensional effect on a flat screen, and its working process is as follows: the screen will first display the picture for the left eye, and then the shutter-type glasses will simultaneously cover the right eye of the audience, which is equivalent to giving the right eye Put on a black blindfold. Then, the screen will quickly switch to the picture for the right eye, at which time the shutter glasses will switch to cover the viewer's left eye. This switching process alternates very quickly, reaching 120 or more times per second, so the left-right switching is imperceptible to the human eye. [0003] In order to realize the function of active shutter glasses to block the left and right eyes of the audience in turn, usually 3D gla...
