The embodiment of the present invention can check the effect of correction rear box splicing it is not necessary that cabinet is barricaded as whole screen, may be implemented
Cabinet is arbitrarily spliced into the calibration result after whole screen.
Second embodiment
The present embodiment on the basis of the above embodiments, is described in detail the technical solution of the embodiment of the present invention.Tool
Body, this method comprises:
(1), it is loaded into cabinet database, which can be the single database for having all cabinet correction coefficient,
It is also possible to multiple databases or a file；
(2), selection needs the cabinet emulated, and cabinet can be selected arbitrarily, for example can choose whole, random multiple, front
It is multiple, multiple, intermediate multiple etc. below, Fig. 2 is referred to, Fig. 2 is that a kind of emulation cabinet provided in an embodiment of the present invention selects to show
It is intended to；
(3), the cabinet number and correction coefficient of each cabinet are read；
(4), be arranged box body splicing after whole screen line direction and column direction cabinet number；
(5), simulation parameter is set, Fig. 3 is referred to, Fig. 3 is that a kind of simulation parameter setting provided in an embodiment of the present invention is shown
It is intended to；
Specific processing step is as follows:
The placement rule of cabinet when splicing is set, such as serial number, random number；
The color of analogous diagram is set；
The color (the screen body color options in corresponding diagram 3) of analogous diagram is, for example, red, green or blue etc., is corresponded to
The full-color cabinet of RGB, the color options of analogous diagram generally only have these three colors；
The mode of analogous diagram is set；
The mode of analogous diagram is divided into three kinds: primary colors figure, grayscale image and pseudo- chromatic graph.Primary colors figure refers to the face of the analogous diagram of selection
What color is, what the color of the analogous diagram of drafting is exactly；Grayscale image refers to that the color of the analogous diagram regardless of selection is, draws
The analogous diagram produced is gray level image forever；Pseudo- chromatic graph refers to the red, green, blue minute in the analogous diagram of drafting at each lamp point
Amount is that different numerical value is assigned according to different correction coefficient, and analogous diagram appears to colour, so being false colour figure.
(6), analogous diagram is drawn；
If the screen body color of selection is red (as shown in Figure 3), the red component of the red colored lamp point in cabinet will be emulated
The red coefficient of benefit of the principal component coefficient (or luminance component coefficient) of coefficient namely red colored lamp point, green light point and blue lamp point,
Namely the complementary color component coefficient (or chromatic component coefficient) of red colored lamp point is added, and takes its brightness reciprocal as the point, it will be bright
Degree multiplies between 0~255 converted in certain proportion, the red component coefficient of red colored lamp point, green light point and blue as
Value is between 0.5~2 after the red coefficient of the benefit of lamp point is added, and for inverse also 0.5~2, ratio can be set to 100, then each
Lamp point is with the anti-relative luminance pushed away of correction coefficient between 0~255.It only need to be by the red component at the lamp point when drawing primary colors figure
Be assigned a value of the anti-relative luminance pushed away, the red, green, blue at the lamp point need to be all assigned a value of when drawing grayscale image it is described it is counter push away it is opposite
Brightness, when drawing pseudo- chromatic graph, color that can be different by different grey-scale assignment is equivalent to 256 grades of gray scales being divided into 256
256 grades of gray scales can also be divided into multiple grades and assign a kind of color for every X grades of gray scale as a grade by grade, excellent
4-6 grades of gray scales of selection of land are as a grade.It is other to be similar in color.Refer to Fig. 4 a- Fig. 4 c, the cabinet that number is 111 with it is other
Cabinet is significantly different, in general if not cabinet itself and remaining cabinet difference are very big, after this box body splicing with remaining cabinet
There is notable difference.
(7), whether uniform each box house in analogous diagram is observed, if, cabinet consistent with preceding Luminance Distribution is corrected
Either with or without gradient phenomenon between cabinet, chooses possible problematic cabinet, re-calibrate.As shown in figure 5, Fig. 5 is the present invention
The no problem analogous diagram that second embodiment provides；As shown in fig. 6, Fig. 6 is edge between the cabinet that second embodiment of the invention provides
Line analogous diagram；As shown in fig. 7, Fig. 7 is that individual cabinets for providing of second embodiment of the invention differ greatly analogous diagram.
If display screen flower is relatively uniform before correcting, correction coefficient distribution is also relatively uniform, and analogous diagram looks
Relatively uniform, if appeared to have in analogous diagram, cabinet is obviously partially bright or partially dark, and the calibration result of in general this cabinet is
It is problematic.
