Second embodiment
The bearing calibration of display unit such as lamp plate is described in detail especially exemplified by specific example below.
Refer to Fig. 2, Fig. 2 is a kind of correction system architecture schematic diagram of lamp plate in second embodiment of the invention.It is described
Correction system architecture includes：LED box (display module) and control system where calibration equipment, target lamp plate.Wherein, correction is set
It is ready for use on and shoots the image that LED box is shown, so as to provides target lamp plate and its adjacent designated area (target lamp plate periphery
Region) image information, namely provide needed for image acquisition region image information；Control system is used for control targe lamp plate
And its image display information of adjacent designated area, obtain the image of the simultaneously required image acquisition region that analysis correction equipment is provided
Information, to obtain brightness or the light tone degrees of data of target lamp plate and its adjacent designated area.
Step 1, position of the target lamp plate in LED box is set：Assuming that LED box size is M*N, target lamp plate size
For A*B (A<M, B<), N origin coordinates of the target lamp plate in LED box：(X,Y).
Step 2, image information is gathered.
Control system opens correction mode, the calibration equipment collection multi-primary color image such as RGB, if LED box to be monochromatic or
It is double-colored, then directly gather corresponding monochromatic or two tone image；
Because the LED box after the completion of the correction of target lamp plate needs and other have corrected LED box and have carried out any splicing, institute
It is consistent with LED box before with the brightness after correction or light tone degrees of data, but when target lamp plate is corrected, at that time
Desired value may be not present or at that time correction LED box environment be modified, it is difficult to accomplish correction after desired value one
Cause and can arbitrarily splice.It is therefore preferable that to open correction coefficient with the image information after being corrected.
Wherein, the target lamp plate and its adjacent designated area, namely required image acquisition region can be by following
Method is obtained：
If X>A, then the beginning column position of image acquisition region is that (X-A) (might be less that this value, but be not less than 0), instead
It, then the beginning column position of image acquisition region is 0；
If (M-X-A)>A, then the end column position of image acquisition region be (X+A+A) (this value can also be more than, but can not
More than M), conversely, then the end column position of image acquisition region is M；
Similarly, if Y>B, then the starting row position of image acquisition region is that (Y-B) (is also smaller than this value, but can not be less than
0), conversely, then the starting row position of image acquisition region is 0；
If (N-Y-B)>B, then the end line position of image acquisition region is (Y+B+B) (also greater than this value, but can not be big
In N), conversely, then the end line position of image acquisition region is N；
Optionally, in other embodiments, image acquisition region can directly be set to whole casing, and be not limited to foregoing
The mode determined according to LED box size, the origin coordinates of target lamp plate size and target lamp plate in LED box.
Step 3, analyze described image pickup area, namely the target lamp plate and its adjacent designated area brightness or bright
Chroma data, is described to simplify explanation so that brightness data is analyzed as an example below；
Premise, is carried out after point location by the image information to image acquisition region, resolution information, has obtained current
The brightness data put pixel-by-pixel of image acquisition region；In order to ensure that after correction current LED box (target lamp plate institute can be allowed
In LED box) and other corrected LED box and carried out any splicing, so when carrying out the data analysis of image acquisition region, need
Data filling is carried out to the periphery of target lamp plate.
Wherein, the principle of data filling processing：Assuming that left hand edge (correspondence X of the target lamp plate in LED box<A), then LED
During box body splicing, this LED box the target lamp plate and right hand edge of the left side LED box when splicing are close to, false in theory
If the Luminance Distribution of all LED boxes is consistent, therefore by the right hand edge data shift copy of the image acquisition region of current LED box
Outside on the left of to image acquisition region, equivalent to broadening image acquisition region, the data of simulation normal data splicing, therefore
When the edge pixel point data amendment of target lamp plate is carried out during subsequent luminance data analysis, the data influence to the left side can be used
The brightness data of current goal lamp plate so that after accomplishing the correction of target lamp plate, LED box where target lamp plate can and other
LED box carries out any splicing.Because when target lamp plate is in left hand edge (the correspondence X of LED box<A), its analysis is obtained
Left side brightness data can (partially dark) less than normal, if directly correction coefficient can be caused using the obtained left side brightness data of analysis
It is excessive；Thus by data filling and amendment, the left side brightness data of target lamp plate can be repaiied and (repair bright) some greatly, thus
The excessive situation of its correction coefficient can be avoided to occur.
Data filling processing particularly may be divided into following several situations：
(1)、X>A,Y>B and (M-X-A)>A, (N-Y-B)>B, data need not be supplemented；
(2) if, X<A, then need LED box since M- | X-A | row to image acquisition region end column number
According to an outside (left side for the starting column of correspondence image pickup area for shift copy to the left-hand line of current LED box brightness data
Side)；
(3) if, (M-X-A)<A, then need by LED box since the starting column of image acquisition region to LED box
| M-X-A-A | the data shift copy of row to the outside of the right-hand column of current LED box data be (correspondence image pickup area
The right side of end column)；
(4) if, Y<B, then by LED box since N- | Y-B | the data of the end line row to image acquisition region are put down
Move the outside (upside of the starting row of correspondence image pickup area) for the upper skidding for copying to current LED box data；
(5) if, (N-Y-B)<B, then by LED box since the starting row of image acquisition region to LED box | N-
Y-B-B | the outside (end of correspondence image pickup area of capable data shift copy to the lower skidding of current LED box data
Capable downside)；
(6) any of the above situation can be combined and use.
Data filling processing is carried out to the brightness data of image acquisition region by the situation actually occurred, to be supplemented
Brightness data after processing.
Step 4, correction coefficient is generated；According to the brightness data after supplement process and the correction target value of setting, institute is generated
State the correction coefficient of target lamp plate.Wherein, when carrying out data filling processing, if being not required to carry out data filling, supplement process
Brightness data and the brightness data of image acquisition region afterwards is identical, in this case can be directly by image acquisition region
In target lamp plate brightness data as original luminance data, in conjunction with setting correction target value, it is possible to which calculating obtains mesh
The brightness point by point correction coefficient of beacon light plate；However, when carrying out data filling processing, can be first if having carried out data filling
The data row and/or data obtained using shift copy is arranged to be repaiied to the brightness data of the respective edges pixel of target lamp plate
Just, obtain brightness data after the amendment of target lamp plate, afterwards will brightness data is as original luminance data after amendment, in conjunction with setting
Determine correction target value, it is possible to calculate the brightness point by point correction coefficient for obtaining target lamp plate.As for according to original brightness or light tone
It is existing mature technology that degrees of data and correction target value, which calculate correction coefficient, therefore be will not be repeated here.Furthermore it is possible to directly
It is repairing for the data row that can also be obtained using shift copy and/or the respective edges pixel of data column count target lamp plate
Direct proportion, further according to respective edges picture of the amendment ratio to target lamp plate after the correction coefficient for obtaining target lamp plate is calculated
The correction coefficient of vegetarian refreshments is modified, and can also obtain required correction coefficient.
Step 5, the correction coefficient of target lamp plate is preserved, for example, is saved in display control card and for example receives card or display unit
In the non-volatile memory device such as the Flash of lamp plate, prevent power-off from losing.
From the foregoing, it will be observed that the present embodiment can realize the brightness data for the lamp plate that simple and quick correction is changed；The mesh newly changed
Beacon light plate reaches unanimity after the correction of this method with lamp plate around in light tone information；And LED box where target lamp plate can
Any splicing is carried out to have corrected LED box with other.
