Signal RVIS, right side line synchronising signal RHIS and right pixel clock signal RPCLK；
Delay detection module, for being examined to the time difference between the left-side images signal and image right signal
Survey, the delay time needed for obtaining；
Output module, for according to the delay time, output image signal realizes the same of left-side images and image right
Step output；
Left-side images and image right are carried out mirror image processing by mirror image interactive module respectively, then by the mirror of left-side images
As being contrasted with image right, mirror image and the left-side images of image right are contrasted, and realize the complete of left-side images and image right
Full synchronism output.
Used as the further improvement of this programme, the mirror image interactive module includes left-side images mirror image device and image right mirror
As device, left-side images and image right are carried out mirror image processing by left-side images mirror image device and image right mirror image device respectively.
Used as the further improvement of this programme, the left-side images mirror image device and image right mirror image device work asynchronously.
Beneficial effects of the present invention：The time difference of left and right sides picture signal can be detected by delay detection module, it is defeated
Go out module regulation left-side images and image right synchronism output.Efficiently solve left and right sides image capture module, i.e., two
The nonsynchronous problem of left and right sides picture signal that camera lens and two sensors are gathered, so as to ensure the display effect of 3D；
Setting is further synchronized to left-side images and image right by mirror image interactive module simultaneously so that be ultimately imaged completely same
Step.
