Abstract
A kind of multiple stage display device realizes that the method that Show Color is unified is a kind of video display processing method, it solves the display difference problem that during multi-screen integrally shows, hardware brings.First, RGB three primary colours and difference arithmetic, respectively each display device debugging configuration CLUT are utilized.Then, when showing image, according to CLUT, color contrast adjustment is carried out to each pixel of each display device, reach overall show be uniformly coordinated.A kind of multiple stage display device realizes that the method that Show Color is unified is mainly used in large screen splicing, multi-screen merges, build projection and intelligent monitoring system etc., a kind of multiple stage display device is provided to realize the Show Color coordinating and unifying, eliminate the hardware differences of display device, reach the method that multi-screen total tune shows.
Description
Technical field
This patent relates to a kind of video display processing method.
Background technology
In specialty audiovisual at present and integrated system market, merge with regard to large screen splicing, multi-screen, build
The Display Techniques such as projection and intelligent monitoring system develop into today, multi-screen display technology increasingly,
Screen wall is put into each big venue and shows in the middle of the application of meeting.
Increasing Large Screen Display Technology obtains frequently using and the doting on of user in the presentation,
So the display difference problem that brings of hardware increasingly draws attention during multi-screen integrally shows, it would be highly desirable to solve
Certainly.
Content of the invention
It is an object of the invention to solve the defect of prior art, provide a kind of multiple stage display device to realize
The Show Color coordinating and unifying, eliminates the hardware differences of display device, reaches multi-screen total tune and show
Method.
For achieving the above object, the present invention is by the following technical solutions:
A kind of multiple stage display device realizes the unified method of Show Color, can DirectX platform,
The 3D rendering platform that OpenGL platform or Ogre platform etc. process function with Shader realizes.
This method, and can adjust in merging in multihead display as software a functional module
The function of the overall Show Color of joint image.Make the coloured image showing on the display device in this way
Seem true, naturally.
Brief description
Fig. 1 is that multiple stage display device realizes that the entirety of the unified method of Show Color realizes structure chart.
Fig. 2 is a display device CLUT configuration calculation method；
Fig. 3 is that multiple stage display device realizes the unified method of Show Color；
Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings:
As it is shown in figure 1, be the debugging configuration data process figure of a display device CLUT.No
Same display device has different difference when display, the display difference of each Color Channel of R, G, B
Different, color change precision difference etc..So needing to configure one and overall display for every display device
The color distortion table of comparisons relatively.
Owing to the data of each table of comparisons are 256*256*256, so engineering construction compares one by one
Regulation is very inefficent.So selecting key point to be adjusted respectively from three primary colours, other face
Look carries out calculating configuration according to key point data.The selection of key point requires according to concrete fine degree can
There to be different choice.
As in figure 2 it is shown, after giving every display device configuration CLUT, each display device every
Individual pixel carries out color contrast adjustment, reach overall show be uniformly coordinated.
Owing to all colours in RGB color spectrum is adjusted by display device, so multiple stage display device
The big figure integral color showing is uniformly coordinated, and more highlights the substitution sense of multihead display.Due to
Color adjusts and carries out each pixel, so the resolution quality of original image will not be reduced.
Claims (4)
1. a multiple stage display device realizes the unified method of Show Color, it is characterised in that: first,
Set up the corresponding color distortion table of comparisons to every display device, preserve every display device and show overall
Color distortion in showing.In display, by the color value of each pixel in image to be displayed, right
The color distortion table of comparisons answering display device finds corresponding color, according to the table of comparisons, color distortion is entered
Row adjusts, the color after then display device display adjusts.So integrate display at multiple stage display device
When one image, equipment difference can be adjusted, reach to show that the total tune of image is unified.
2. a multiple stage display device realizes the unified method of Show Color, it is characterised in that: color pair
Enumerate the discrepancy adjustment value of color according to R, G, B principle of three primary colours according to table, all colours table of comparisons is
The form of the color value after the primitive color of 256*256*256 color and the adjustment of this display device.
3. a multiple stage display device realizes the unified method of Show Color, it is characterised in that: utilize
Shader technology, is processed to each pixel of display image.
4. a multiple stage display device realizes the unified method of Show Color, it is characterised in that: due to face
The look table of comparisons is 256*256*256 color contrast, so manually carrying out difference to each color value
Adjust and arrange for implementing very inefficent.This method uses the method gradually refining, to color value
It is adjusted arranging.First, divide R, G, B three primary colours to adjust key point color value therein, then enter
Row mathematic interpolation obtains all three primary colours CLUTs, by all colours table of comparisons of three primary colours mixing.
The adjustment accuracy of CLUT can be set according to specific requirement.
