Detailed description of the invention
The solution of the embodiment of the present invention is mainly: one red with upper by the infrared synchronous signal that will receive
Differ from the actual time between external synchronization signal and the preset standard time difference of the adjacent infrared synchronous signal set
Compare, according to difference described actual time and the order of magnitude of the difference of described preset standard time difference
Analyze the current left/right eye optimal opening time obtaining 3D glasses, most preferably open further according to by current left/right eye
Open left eye that Time Calculation goes out, the right eye opening time carries out opening of 3D glasses left/right eye in current period
Close switching, thus the error that causes of the internal clocking instability solving single-chip microcomputer in 3D glasses and outside red
The interference of external signal.
As it is shown in figure 1, first embodiment of the invention proposes the anti-interference method of a kind of 3D glasses, including:
Step S101, after 3D glasses receive infrared synchronous signal, calculates this infrared synchronous signal and upper
Actual time between infrared synchronous signal is poor；
3D glasses capture left/right eye infrared synchronous signal, receives left eye infrared synchronous at this with 3D glasses
Illustrating as a example by signal, it is infrared same to should refer to left eye that 3D glasses receive right eye infrared synchronous signal principle
Step signal, repeats no more.After 3D glasses receive left eye infrared synchronous signal, open left eye and close right eye,
Terminated the timing in a upper cycle simultaneously, and it is one infrared with upper to calculate the infrared synchronous signal that is currently received
Difference T3 i.e. time interval actual time between synchronizing signal.
Step S102, compares analysis by difference described actual time with preset standard time difference, if described

Difference described actual time is set as the current left/right eye optimal opening time of 3D glasses, otherwise, by institute
State preset standard time difference and be set as the current left/right eye optimal opening time of 3D glasses；
Preset standard time difference T0 and the very first time that set adjacent infrared synchronous signal under optimum state are poor
T1, the described very first time, difference T1 was a certain size value deviateing described preset standard time difference T0, and partially
From described preset standard time difference T0 size be difference T1 of the described very first time time impact of 3D effect is existed
In acceptable scope；
Difference T3 described actual time is compared with described preset standard time difference T0, calculates and obtain institute
State absolute value | T3-T0 | of the difference of difference T3 actual time and described preset standard time difference T0, when | T3-
T0 | < during T1, illustrate that current difference T3 actual time is in the range of normal, noiseless to 3D effect
Impact, then be set as the current left/right eye optimal opening time of 3D glasses by current difference T3 actual time；
As | T3-T0 | > T1 time, illustrate that current actual time, difference T3 deviateed described preset standard time difference T0
It is worth excessive, according to current difference T3 actual time, then 3D effect can be produced bigger interference, this
Time, just directly described preset standard time difference T0 is set as that the current left/right eye of 3D glasses is most preferably opened
Time, to eliminate the interference that 3D effect is produced, improve the capacity of resisting disturbance of 3D glasses.

When absolute value | T3-T0 | of the difference of time difference T3 and described preset standard time difference T0 is more than described second
Between difference T2 time, illustrate described actual time difference T3 deviate described preset standard time difference T0 excessive, may
For interference signal, then directly described preset standard time difference T0 is set as the current left/right eye of 3D glasses
The optimal opening time, eliminate interference signal and deviate the signal that described preset standard time difference T0 is excessive,
Avoid it that 3D effect is produced interference.
Step S103, carries out opening of 3D glasses left/right eye according to the described current left/right eye optimal opening time

During left eye opening time in the current period gone out, close left eye and open right eye, set maximum for right eye and open
Open time and minimum opening time, when the right eye actual opening time is more than the maximum opening time set,
If now 3D glasses also do not receive next left eye infrared synchronous signal, it is determined that next left eye infrared synchronous is believed
Number there may be the situation of time delay or loss, then do not continue to wait next left eye infrared synchronous signal, directly
Connect closedown 3D glasses right eye, open 3D glasses left eye, it is to avoid because left eye infrared synchronous signal is by outside
Interference produces time delay or loss, thus 3D effect produces the situation of interference；When receiving, next left eye is red
When external synchronization signal and right eye actual opening time are less than the minimum opening time set, it is determined that receive
Next left eye infrared synchronous signal is interference signal or the invalid signals arrived in advance, then continue waiting for left eye
