In the present embodiment, according to actual combination information generating run interface; Obtain with reference to display information; According to the target color information calculating residue display screen with reference to display information; Display screen is selected according to target color information.After calculating target color information with reference to display information, the combination according to the display screen composition of target color information selection is watched from observer position, and its integral color is consistent, can meet the requirement of observer.
Be described above an embodiment of method for regulating color consistency of multi-display screen provided by the invention, below another embodiment of method for regulating color consistency of multi-display screen provided by the invention be described.
Refer to another embodiment of Fig. 2 method for regulating color consistency of multi-display screen provided by the invention to comprise:
201, according to actual displayed screen dimensions, quantity and arrangement mode generating run interface;
In the present embodiment, the information such as the size of the actual combination that service provider can provide according to client, the size of display screen, the quantity of required display screen and the arrangement mode of display screen, set up on computers and show combination model manipulation interface.
Refer to Fig. 3, Fig. 3 is for showing combination model manipulation interface schematic diagram, and this combination is 2*4 unit, is made up of 8 pieces of display screens, and subsequent step can at the enterprising line operate of this operation interface.
202, obtain with reference to the distance between display screen center and observer and the colouring information with reference to display screen;
In the present embodiment, the viewing distance wherein in operation interface refers to the length at observer's distance reference display screen center.Refer to reference to brightness of display screen and colourity with reference to display screen colouring information.
It should be noted that, will select with reference to display screen from the following a line of combination, because this height is pleasing to the eye direct-view height, brightness, the colourity of reference display screen then need client to provide.
203, by formula, calculate according to reference to the distance between display screen center and observer and with reference to display screen colouring information the target color information remaining display screen;
In the present embodiment, in step 202, service provider obtains with reference to after the brightness of display screen, colorimetric parameter, inputs the above-mentioned brightness with reference to display screen, colorimetric parameter, can demonstrate the object brightness information of residue display screen on operation interface.
First according to reference to the line number of display screen, row number and with reference to display screen central point to observer's distance, and calculate the length of each display screen of residue apart from observer with reference to the dimension information of display screen, specific formula for calculation is as follows:
wherein, i represents residue display screen line number, and j represents residue display screen row number, and c represents line number, row number with reference to display screen; l
ccrepresent the length with reference to display screen central point distance observer, l
ijrepresent with reference display screen line number, arrange number length of all inconsistent display screen central point distance observer; l
pkrepresent the width of residue display screen, l
pcrepresent the length of residue display screen.I ≠ c, j ≠ c, represent residue display screen and the different row of reference display screen, heterotaxy; I=c, j ≠ c, represents that residue display screen and reference display screen are gone together, heterotaxy; I ≠ c, j=c, represent display screen and the different row of reference unit, same column.
Again according to the length of residue each display screen distance observer, calculate residue display screen object brightness, computing formula is as follows:
wherein, Y
ccrepresent the brightness with reference to display screen central spot, Y
ijrepresent and reference unit row, column number all inconsistent display screen Strehl ratio;
Calculate target colorimetric according to each residue display screen object brightness again, can prior art be regarded as according to brightness calculation colourity, not illustrate herein.
204, display screen is selected according to target color information.
In the present embodiment, service provider carries out the selection of display screen according to the target colorimetric that operation interface shows and object brightness.Concrete system of selection is described for 00 screen.
It should be noted that, display screen object brightness information comprises: object brightness, the luminance deviation (comprising positivity bias and negative sense deviation) of 00 screen; Display screen target colorimetric information comprises: target colorimetric, the chromaticity distortion (comprising positivity bias and negative sense deviation) of 00 screen;
First, in the display screen meeting object brightness, the display screen meeting target colorimetric will be selected further;
Secondly, if selected display screen is greater than 4, then a step reduces brightness, chromaticity distortion value, again carries out selecting until be left 4.If select deviate enough little, display screen is still greater than 4, then all display screens satisfied condition are performed operation below.
By meet alternative condition display screen numbering and store information association to operation interface corresponding 00 screen on, click 00 screen namely can jump out alternative display screen numbering and storage information.
It should be noted that, chosen content order is interchangeable, and namely advanced circumstances in which people get things ready for a trip degree is selected, then carries out brightness selection, and brightness is selected to need to select in the display screen numbering meeting colourity selection.
In order to the display screen that can realize spelling wall optimal display result can be selected, can also proceed as follows after completing the aforementioned steps:
First, to each display screen of spelling wall from top to bottom, from left to right, the display screen satisfied condition numbering is carried out giving birth to sequence arrangement than object brightness deviation by intrinsic brilliance, and exports statistics.If there is a display screen not meet this brightness sort criteria, then stop the arrangement under this brightness conditions; If same condition has multiple stage display screen to meet the demands, then find the minimum display screen of deviation.
Secondly, to the display screen meeting above-mentioned rank results, then arrange by colourity and target colorimetric deviation forward, negative sense, and export statistics respectively.If there is a display screen not meet this colourity sort criteria, then stop the arrangement under this chrominance requirements; If same condition has multiple stage display screen to meet the demands, then find the minimum display screen of deviation.
Again, descending sort is carried out by intrinsic brilliance than object brightness deviation.In like manner, there is a display screen not meet this brightness sort criteria, then stop the arrangement under this brightness conditions; If same condition has multiple stage display screen to meet the demands, then find the minimum display screen of deviation.Again divide chromaticity distortion forward, negative sense arranges, in like manner, have a display screen not meet this colourity sort criteria, then stop the arrangement under this chrominance requirements.If same condition has multiple stage display screen to meet the demands, then find the minimum display screen of deviation.
Meet 2 kinds of arrangements of above-mentioned condition if at least exist, then select in often kind of arrangement, arrangement that the standard deviation of all display screen intrinsic brilliances and target brightness value is minimum; If luminance standard difference is equal, then calculate the actual colourity of all display screens and the minimum aberration of target colorimetric deviation; If aberration is also equal, then Stochastic choice wherein one group arranges.Standard deviation and the Colorimetry formula of intrinsic brilliance and target brightness value are as follows:
