The following description of the embodiments is not intended to limit the preferred embodiments. Although a logical order is depicted in the flowchart, in some cases the steps shown or described may be performed in an order different than depicted in the figures.

Referring to fig. 1, a first embodiment of the present application is presented, and the specific flow of the color debugging method includes the following steps:

step 101, obtaining color matching characteristics of a sample machine to be adjusted;

step 102, determining target color to be mixed features according to a white solid color theory and pixel values of each color channel of the color to be mixed features;

Step 103, adjusting preset standard color characteristics according to the target color characteristics to be mixed to obtain target standard color characteristics;

and 104, performing color debugging on the sample waiting machine according to the target color waiting characteristic and the target standard color characteristic.

In this embodiment, the sample machine to be adjusted may be a device with a display screen, such as a computer, a television, a mobile phone, etc., when the sample machine to be adjusted needs to be color adjusted, the color adjusting device obtains the color feature to be adjusted of the sample machine to be adjusted, and adjusts the color feature to be adjusted according to the white solid color theory and the pixel value of each color channel of the color feature to be adjusted to determine the target color feature to be adjusted; the color debugging equipment acquires preset standard color characteristics corresponding to a standard prototype, wherein the standard prototype can be equipment with a display screen, such as a computer, a television, a mobile phone and the like, capable of displaying standard colors, and adjusts the standard color characteristics according to target color characteristics to be adjusted to obtain target standard color characteristics; the color debugging equipment generates a corresponding color characteristic lookup table according to the target color characteristic to be debugged and the target standard color characteristic, and performs color debugging on the sample machine to be debugged based on the color characteristic lookup table.

The color debugging equipment of the embodiment obtains the color characteristic to be mixed of the sample machine to be debugged; determining target color characteristics to be mixed according to a white solid color theory and pixel values of each color channel of the color characteristics to be mixed; adjusting preset standard color characteristics according to target color characteristics to be mixed to obtain target standard color characteristics; and generating a corresponding color characteristic lookup table according to the target color characteristic to be adjusted and the target standard color characteristic, and performing color adjustment on the sample machine to be adjusted based on the color characteristic lookup table. The color adjustment method comprises the steps of adjusting color characteristics to be adjusted through a white solid color theory and pixel values of all color channels, adjusting preset standard color characteristics according to target color characteristics to be adjusted, improving the accuracy of color characteristics to be adjusted and standard color characteristic adjustment expression, generating a corresponding color characteristic lookup table to carry out color adjustment on a sample machine to be adjusted based on the adjusted color characteristics to be adjusted and the standard color characteristics, and improving the efficiency and accuracy of color adjustment.

Specifically, each step is described in detail below:

in the step, the color debugging equipment responds to a color debugging instruction, firstly determines a sample machine to be debugged, then controls the sample machine to be debugged to display various colors, and further obtains the color characteristic to be debugged of the sample machine to be debugged; specifically, in order to obtain the color characteristics to be adjusted of the sample machine to be adjusted, the X/Y/Z data of the W/R/G/B pure color picture of the N-order is generally collected. The values of W/R/G/B are 0, 255 in RGB color space, i.e. W/R/G/B can be equal to 0/1/2 … … or 256 values. When white W is required to be a solid color, r=g=b is required, and only 256R/G/B combinations satisfying the condition are required. Similarly, red R is a pure color request g=b=0, green G is a pure color request r=b=0, and blue B is a pure color request r=g=0, and only 256R/G/B combinations satisfying the condition are provided. In order to obtain the color feature to be adjusted of the sample machine, the 1024 (4 times of N) R/G/B values can be used as input of the sample machine to be adjusted, and meanwhile, the X/Y/Z values of the display color of the sample machine to be adjusted in the CIEXYZ color space are respectively measured to obtain the color feature to be adjusted of the sample machine to be adjusted.

in the step, the color debugging equipment determines target color to be adjusted characteristics according to a white solid color theory and pixel values of all color channels of the color to be adjusted characteristics; it can be understood that the color feature to be adjusted comprises three color channels R/G/B, the pixel value range of each color channel is [0, 255], the pixel value grades are divided according to the pixel value of each color channel of the color feature to be adjusted, further, the target weight corresponding to each pixel value grade is determined according to the white solid color theory and the color feature to be adjusted, and the target color feature to be adjusted is determined based on the target weight corresponding to each pixel value grade and the color feature to be adjusted.

Specifically, step 102 includes:

step 1021, dividing the pixel value level according to the pixel value of each color channel corresponding to the color feature to be mixed;

in the step, the color debugging equipment divides the pixel value grades according to the pixel value of each color channel corresponding to the color feature to be color-mixed; the color feature to be adjusted comprises three R/G/B color channels, the pixel value range of each color channel is [0, 255], and preferably, the color debugging equipment determines each pixel value of 0-255 to be divided into a pixel value grade; optionally, the color debugging device divides a pixel value level in the value range [0, 255] at intervals of a preset length according to the preset length.

Step 1022, calculating the white color feature corresponding to the pixel value level according to the white solid color theory for each pixel value level;

in this step, the color debugging device calculates, for each pixel value level, a white color feature corresponding to the pixel value level according to the white solid color theory after dividing the pixel value level. Specifically, the white solid color theory is the W solid color theory, and if the color feature to be tinted of the sample machine to be tinted is strictly linear, the following formula should be satisfied when r=g=b=n (0+.n (integer). Ltoreq.255):

Xwn＝Xrn+Xgn+Xbn

Ywn＝Yrn+Ygn+Ybn

Zwn＝Zrn+Zgn+Zbn

wherein Xwn/Ywn/Zwn is the X/Y/Z value of the display color of the sample to be modulated measured when R/G/B=n/n/n, the display color of the sample to be modulated is white, xwn/Ywn/Zwn is a white color feature, when n takes different values, xwn/Ywn/Zwn corresponds to a white color feature of the pixel value class, R/G/B=n/0/0 measures Xrn/Yrn/Zrn corresponds to a red color feature, R/G/B=0/n/0 measures Xgn/Ygn/Zgn corresponds to a green color feature, and R/G/B=0/0/n measures Xbn/Ybn/Zbn corresponds to a blue color feature. That is, the white color feature is calculated from the red color feature, the green color feature, and the blue color feature.

Step 1023, calculating a target weight corresponding to the pixel value grade according to the to-be-tinted color characteristic and the corresponding white color characteristic in the pixel value grade;

in the step, the color debugging equipment calculates a target weight corresponding to the pixel value grade according to the to-be-color-mixed characteristic and the corresponding white color characteristic in the pixel value grade; specifically, the color feature to be tuned of the sample machine to be tuned is not strictly linear, and the concept of R/G/B weight coefficients of each stage needs to be introduced, which are respectively Prn, pgn and Pbn, and when r=g=b=n (0+.n (integer). Ltoreq.255), the following formula should be satisfied:

Xwn＝Prn*Xrn+Pgn*Xgn+Pbn*Xbn

Ywn＝Prn*Yrn+Pgn*Ygn+Pbn*Ybn

Zwn＝Prn*Zrn+Pgn*Zgn+Pbn*Zbn

because the X/Y/Z value of the W/R/G/B solid color is a known test quantity, the n-th-stage R/G/B weight coefficient is obtained as follows:

that is, the color debugging apparatus calculates the target weights Prn, pgn, and Pbn (0.ltoreq.n (integer). Ltoreq.255) corresponding to the respective pixel value ranks from the white color feature Xwn/Ywn/Zwn of the respective pixel value ranks and the to-be-toned color feature Xrn/Yrn/Zrn, xgn/Ygn/Zgn, xbn/Ybn/Zbn of the respective pixel value ranks.

Step 1024, adjusting the to-be-tinted feature according to the target weight corresponding to each pixel value level, and determining a target to-be-tinted feature.

In the step, the color debugging equipment adjusts the color feature to be adjusted according to the target weight corresponding to each pixel value grade, and determines the target color feature to be adjusted. Specifically, the color to be toned features include Xrn/Yrn/Zrn, xgn/Ygn/Zgn, xbn/Ybn/Zbn,9 feature values, xrn is the value of n for the red channel on the X-axis of the color to be toned feature in the CIEXYZ color space, xgn is the value of n for the green channel on the Y-axis of the color to be toned feature in the CIEXYZ color space, zbn is the value of n for the blue channel on the Z-axis of the color to be toned feature in the CIEXYZ color space, and other feature value understanding can refer to the above explanation and will not be repeated herein. The values n of the characteristic values are different, and colors represented by the to-be-tinted characteristic are also different, so that the size of the to-be-tinted characteristic in each color channel pixel value needs to be determined, the pixel value grade of each color channel pixel value is determined, the target weight corresponding to each color channel pixel value is further determined, the to-be-tinted characteristic is adjusted based on the target weight, and the target to-be-tinted characteristic is determined.

Specifically, step 1024 includes:

step 10241, for each to-be-tinted feature, determining the pixel value grade to which each color channel pixel value belongs according to the size of each color channel pixel value corresponding to the to-be-tinted feature;

In the step, the color debugging equipment determines the pixel value grade of each color channel pixel value according to the size of each color channel pixel value corresponding to each color feature to be color-blended; illustratively, the to-be-tinted color features include Xr5/Yr30/Zr100, xg5/Yg30/Zg100, xb5/Yb30/Zb100, and correspondingly, each color channel pixel value is determined to include 5, 30, and 100, and further, the pixel value level to which each color channel pixel value belongs is determined to include a 5 th level, a 30 th level, and a 100 th level.

Step 10242, determining the target weight corresponding to each color channel pixel value according to the pixel value grade to which each color channel pixel value belongs;

in this step, the color debugging device determines the target weight corresponding to each color channel pixel value according to the pixel value level to which each color channel pixel value belongs. For example, the to-be-tinted color features include Xr5/Yr30/Zr100, xg5/Yg30/Zg100, xb5/Yb30/Zb100, and correspondingly, each color channel pixel value is determined to include 5, 30 and 100, and further, the pixel value level to which each color channel pixel value belongs is determined to include a 5 th level, a 30 th level and a 100 th level, and then the target weights corresponding to each color channel pixel value are respectively the target weight corresponding to the 5 th level, the target weight corresponding to the 30 th level and the target weight corresponding to the 100 th level.

Step 10243, calculating the target color feature to be mixed according to the color channel features corresponding to the color feature to be mixed and the target weights corresponding to the pixel values of the color channels.

In the step, the color debugging equipment calculates target color to be adjusted according to the color channel characteristics corresponding to the color to be adjusted and the target weights corresponding to the pixel values of the color channels. Specifically, the formula for calculating the target color feature to be mixed is as follows:

Xijk＝Pri*Xri+Pgj*Xgj+Pbk*Xbk

Yijk＝Pri*Yri+Pgj*Ygj+Pbk*Ybk

Zijk＝Pri*Zri+Pgj*Zgj+Pbk*Zbk

the color matching method comprises the steps of taking Xijk/YIjk/Zijk as a target color to be matched, taking Pri as a target weight corresponding to the color to be matched when the value of a red channel on an XYZ axis in a CIEXYZ color space is i, taking Pgj as a target weight corresponding to the color to be matched when the value of a green channel on an XYZ axis in the CIEXYZ color space is j, taking Pbk as a target weight corresponding to the color to be matched when the value of a blue channel on an XYZ axis in the CIEXYZ color space is k, and taking Xri/Yrj/Zrk, xgi/Ygj/Zgk and Xbi/Ybj/Zbk as color channel characteristics corresponding to the color to be matched respectively, wherein the values of the color to be matched on the XYZ axis of the color to be matched are the same, and the values of the color to be matched on the XYZ axis of the green channel in the CIEXYZ color space are the same.

Further, the values of the red channels of the color to be mixed on the XYZ axes in the CIEXYZ color space may be different, the values of the green channels of the color to be mixed on the XYZ axes in the CIEXYZ color space may be different, the values of the blue channels of the color to be mixed on the XYZ axes in the CIEXYZ color space may be different, and at this time, the formula for calculating the target color to be mixed features is as follows:

Xabc＝Pra*Xra+Pgb*Xgb+Pbc*Xbc

Ydef＝Prd*Yrd+Pge*Yge+Pbf*Ybf

Zghi＝Prg*Zrg+Pgh*Zgh+Pbi*Zbi

at this time, the color debugging device needs to determine the target weights corresponding to the a-i9 pixel value grades, and further calculate the target color feature to be adjusted.

in the step, the color debugging equipment adjusts preset standard color characteristics according to the target color characteristics to be adjusted to obtain target standard color characteristics. It should be noted that, the preset standard color characteristic is obtained from the standard prototype by the color debugging device, and the color gamut, brightness and color temperature of the standard prototype and the color gamut, brightness and color temperature of the sample to be debugged have certain differences, so that the preset standard color characteristic is required to be adjusted to obtain the target standard color characteristic, so that the color gamut, brightness and color temperature expressed in the target standard color characteristic are consistent with the color gamut, brightness and color temperature of the sample to be debugged, and the accuracy of subsequent color debugging is improved.

It should be noted that, regarding the color gamut, it is generally required that the sample to be adjusted has an optical scheme similar to that of the standard sample, for example, when the sample to be adjusted and the target sample are both liquid crystal televisions, it is required to ensure that the backlight types (normal powder/new red powder/quantum dots) and the panel color resistance (material/thickness) states of the sample to be adjusted are consistent, and so on, therefore, the standard sample having an optical scheme similar to that of the sample to be adjusted is generally selected, and the color gamut difference between the sample to be adjusted and the standard sample is eliminated; for brightness and color temperature differences, brightness normalization and color temperature debugging processing is generally performed.

Specifically, step 103 includes:

step 1031, adjusting the pixel values of each color channel corresponding to the target color feature to be mixed and the preset standard color feature to be the same;

in the step, the color debugging equipment adjusts the pixel values of all color channels corresponding to the target color feature to be mixed and the preset standard color feature to be the same; illustratively, r=g=b=m is adjusted so that the standard prototype displays white, the corresponding standard white color features have the same values of three red, green and blue channels on XYZ axes in the CIEXYZ color space, the standard white color features are Xtm/Ytm/Ztm so that the sample to be sampled displays white, the corresponding color features to be whitened have the same values of three red, green and blue channels on XYZ axes in the CIEXYZ color space, and the color feature to be whitened is Xdm/Ydm/Zdm.

Step 1032, calculating an adjustment coefficient according to the target color feature to be adjusted and the pixel value of each color channel after the adjustment of the preset standard color feature;

in the step, the color debugging equipment calculates an adjustment coefficient according to the target color feature to be adjusted and the pixel value of each color channel after the adjustment of the preset standard color feature; specifically, when the sample to be adjusted and the standard sample have only brightness difference, namely only the brightness adjustment coefficient is needed to be calculated, and the brightness adjustment coefficient is set as C1 at this time, so that the brightness adjustment coefficient meets the following conditions: c1 The luminance adjustment coefficient is calculated according to the values of the three channels of red, green and blue on the Y axis in the CIEXYZ color space of the target color feature to be adjusted and the values of the three channels of red, green and blue on the Y axis in the CIEXYZ color space of the standard color feature to be adjusted. When the brightness and color temperature difference exists between the sample machine to be regulated and the standard sample machine, namely the brightness and color temperature adjustment coefficient needs to be calculated, and the brightness adjustment coefficient is set as C2 at the moment, so that the brightness adjustment coefficient meets the following requirements: c2 The brightness and color temperature adjustment coefficients are calculated according to the values of three channels of red, green and blue on the XYZ axis in the CIEXYZ color space of the target color feature to be adjusted and the values of three channels of red, green and blue on the XYZ axis in the CIEXYZ color space of the standard color feature to be adjusted.

Step 1033, calculating a target standard color feature according to the adjustment coefficient and the standard color feature.

In this step, the color debugging device calculates a target standard color feature based on the adjustment coefficient and the standard color feature. Specifically, when there is only a brightness difference between the sample machine to be adjusted and the standard sample machine, the Xtm/Ytm/Ztm value of the target sample machine is adjusted to be Xt1/Yt1/Zt1 by the brightness adjustment coefficient C1, that is, xt1= Xtm ×c1, yt1=ytm×c1, zt1= Ztm ×c1, and the obtained xt1/yt1/Zt1 is the target standard color feature. When the brightness and color temperature difference exists between the sample to be adjusted and the standard sample, the Xtm/Ytm/Ztm value of the target sample is adjusted to be Xt 2/Ytm 2/Zt2 through the brightness and color temperature adjustment coefficient C2, namely Xt2= Xtm ×c2, yt2=ytm×c2, zt2= Ztm ×c2, and the obtained Xt2/yt2/Zt2 is the target standard color characteristic.

In the step, the color debugging equipment performs color debugging on the sample to be debugged according to the target color feature to be debugged and the target standard color feature after obtaining the target color feature to be debugged and the target standard color feature. Specifically, the color debugging equipment performs color debugging on the target color feature to be debugged according to the target standard color feature, further determines a reference color feature in the target color feature to be debugged, and uses the reference color feature in the sample machine to be debugged.

Specifically, step 104 includes:

step 1041, converting the target color feature to be color-adjusted and the target color feature to an LAB color space to obtain a target color LAB feature to be color-adjusted and a target standard color LAB feature;

in the step, the color debugging equipment converts the target color characteristic to be color-mixed and the target color characteristic into an LAB color space to obtain the target color LAB characteristic to be color-mixed and the target standard color LAB characteristic; specifically, the target color feature to be tinted and the target color feature are color features in the CIEXYZ color space, so that the target color feature to be tinted and the target color feature need to be converted into the LAB color space, so that the color difference can be calculated conveniently. It should be noted that, the CIELAB/CIEXYZ color space conversion method is a mature technology, and will not be repeated here.

Step 1042, generating a color feature lookup table according to the target color LAB feature to be adjusted and the target standard color LAB feature, and performing color adjustment on the sample machine to be adjusted based on the color feature lookup table.

In the step, the color debugging equipment calculates the color difference between the target color LAB characteristic to be debugged and the target standard color LAB characteristic based on the CIEDE2000 color difference calculation method, further determines the reference color characteristic in the target color characteristic to be debugged according to the color difference to finish debugging the target color characteristic to be debugged, and then adds the reference color characteristic into the color characteristic lookup table to be applied to a sample machine to be debugged. It should be noted that, the CIEDE2000 color difference calculation method is a mature technology, and is not repeated here.

Further, step 1042 comprises:

step 10421, calculating, for each target standard color LAB feature, a color difference between each target color LAB feature to be color-mixed and the target standard color LAB feature, and obtaining a reference color LAB feature corresponding to the minimum color difference;

in the step, color debugging equipment calculates color differences between each target color LAB characteristic to be adjusted in a sample machine and each target standard color LAB characteristic based on a CIEDE2000 color difference calculation method, and obtains the target color LAB characteristic to be adjusted corresponding to the minimum color difference from each target color LAB characteristic to be adjusted as a reference color LAB characteristic. The method comprises the steps of determining target standard color LAB characteristics corresponding to purple in all target standard color LAB characteristics, calculating chromatic aberration between each target color LAB characteristic to be tinted in a sample machine to be tinted and the target standard color LAB characteristics corresponding to the purple based on a CIEDE2000 chromatic aberration calculation method, and obtaining target color LAB characteristics corresponding to the minimum chromatic aberration between each target color LAB characteristic to be tinted and the target standard color LAB characteristics corresponding to the purple as reference color LAB characteristics of the sample machine to be tinted; it will be appreciated that for each color that the sample machine to be adapted is capable of displaying, the reference color LAB characteristics corresponding to each color may be determined in the exemplary manner described above.

Preferably, the color debugging device determines target standard color LAB features corresponding to target colors in all target standard color LAB features, acquires target color LAB feature sets capable of representing the target colors in all target color LAB features, calculates color differences between each target color LAB feature to be color-blended in the target color LAB feature sets representing the target colors and the target standard color LAB features corresponding to the target colors based on a CIEDE2000 color difference calculation method, and further selects target color LAB features to be color-blended with the smallest color differences in the target color LAB feature sets representing the target colors as reference color LAB features of the target colors to be subjected to sample debugging.

Step 10422, summarizing the reference color LAB features corresponding to the target standard color LAB features to obtain a color feature lookup table.

In the step, the color debugging equipment gathers reference color LAB characteristics corresponding to each target standard color LAB characteristic, converts the reference color LAB characteristics from a CIELAB color space to a CIEXYZ color space to obtain reference color characteristics in the CIEXYZ color space, wherein the reference color characteristics are some color characteristics in target color characteristics to be debugged in a sample machine to be debugged, adds all the reference color characteristics into a color characteristic lookup table, and applies the color characteristic lookup table to the sample machine to be debugged, and the color debugging of the sample machine to be debugged is completed.

Further, as shown in fig. 2, after the debugging is completed, the method includes the steps of:

step 105, responding to the display instruction, and determining a target color;

step 106, searching the color characteristics corresponding to the target color in the color characteristic lookup table;

step 107, generating and displaying the target color based on the color feature.

In steps 105 to 107, after finishing debugging, obtaining a target prototype, entering an application scene, responding to a display instruction by the target prototype, determining a target color, randomly determining a color feature to be mixed which can represent the target color, inputting the color feature to be mixed into a color feature lookup table, and searching a color feature corresponding to the target color, wherein the color feature is a reference color feature of the target color displayed by the sample to be debugged determined in the debugging stage, and the target prototype generates and displays the target color based on the color feature, so that the displayed target color can be close to or equal to a standard display state corresponding to the target color.
