When lattice matrix carries out the superposition of coincidence formula；Pixel grid with work image is not superimposed the pixel grid of interference image；Blank
In pixel grid, the pixel grid of corresponding superposition interference image.
In a kind of above-mentioned anti-shooting system of screen peep-proof, the polarization type LCD MODULE screen resolution is more than 4k.
The present invention has the following advantages that compared with prior art：
(1) vision signal interference system of the present invention is handled by the work image to input, and interference image, which generates, to be calculated
Method and work resume image.The video image output of generation is encrypted work image, i.e. jamming pattern, is mixed to be formed
Random image is ready；
(2) present invention uses high-resolution polarization type display, realizes that the interference image of work image and insertion sends out phase
Mutually vertical polarised light, has obtained the image of complete confusion, to reach the requirement of secrecy；
(3) present invention employs polaroid glasses, realize filtering interference image, it is seen that really work image.
Description of the drawings
Fig. 1 is present system schematic diagram；
Fig. 2 is the work image after the present invention plus interference；
Fig. 3 is that the present invention takes the work image observed after polarising glass.
Specific implementation mode
The present invention is described in further detail in the following with reference to the drawings and specific embodiments：
The present invention proposes a kind of anti-anti- camera system of snooping of screen, for being transferred to the work of video image countermeasure set
After image carries out certain encryption, it is sent on polarization type liquid crystal display and is shown.The anti-snooping of screen is prevented taking pictures
System is using the digital signal processing module of high speed as central processing unit, for realizing complicated character script size identification, interference
The generation etc. of image.
It is system schematic as shown in Figure 1, as seen from the figure, a kind of anti-shooting system of screen peep-proof, including Digital Signal Processing
