本步骤中，画面测量数据为用于表征显示画面的RGB值，颜色测量数据为用于表征用户观看显示画面的颜色值，其中，颜色值可采用三刺激值XYZ、CIELAB、CIELUV等颜色表示法进行表示。通常，每个RGB值都对应一个颜色值，比如RGB(0,0,0)对应三刺激值XYZ(0.41,0.38,0.66)。In this step, the picture measurement data is the RGB value used to characterize the display screen, and the color measurement data is the color value used to characterize the display screen viewed by the user. Among them, the color value can use color representation methods such as tristimulus values XYZ, CIELAB, and CIELUV. to express. Usually, each RGB value corresponds to a color value, such as RGB(0,0,0) corresponding to the tristimulus value XYZ(0.41,0.38,0.66).

The screen measurement data and color measurement data are fitted to generate matrix coefficients, and then the matrix coefficients are associated with the color range to obtain a coefficient structure group. Among them, the linear regression algorithm is the least squares method and so on.

在S123中，本实施例可根据表5的数据及显示测量数据，生成颜色校准文件。由于本实施例能够根据使用者自定义的颜色自定义数据，结合原始画面表，扩充和丰富了颜色自定义数据，由此得到的自定义颜色扩充表既可满足和反映出使用者的自定义颜色的需求，又可符合屏幕出厂时原始画面表所界定的颜色显示规则，以保证使用者既可自定义屏幕所显示的画面，又能够保证屏幕可靠准确地进行对应RGB配比颜色的画面显示。In S123, this embodiment can generate a color calibration file based on the data in Table 5 and the display measurement data. Since this embodiment can expand and enrich the color custom data according to the user-defined color custom data, combined with the original picture table, the resulting custom color expansion table can satisfy and reflect the user's customization The color requirements must also comply with the color display rules defined in the original picture table when the screen leaves the factory, ensuring that users can not only customize the picture displayed on the screen, but also ensure that the screen can reliably and accurately display pictures corresponding to RGB color ratios. .
在一些实施例中，颜色自定义数据包括自定义颜色初始表，根据原始画面表扩充颜色自定义数据以得到自定义颜色扩充表包括以下步骤：In some embodiments, the color customization data includes a custom color initial table, and expanding the color customization data according to the original picture table to obtain a custom color expansion table includes the following steps:
S1221：根据原始画面表，依序获取每个原始画面数据。S1221: Acquire each original picture data sequentially according to the original picture table.
S1222：若自定义颜色初始表不包含原始画面数据，则根据插值算法，计算原始画面数据对应的目标颜色数据，执行步骤S1223。S1222: If the custom color initial table does not contain the original picture data, calculate the target color data corresponding to the original picture data according to the interpolation algorithm, and execute step S1223.

举例而言，请结合表3，本实施例先获取原始画面数据{r10,g10,b10}。本实施例判断原始画面数据{r10,g10,b10}是否存在于表4中，由表4可知，表4并不包含原始画面数据{r10,g10,b10}，因此，本实施例根据插值算法，计算原始画面数据{r10,g10,b10}对应的目标颜色数据{X10',Y10',Z10'}，并将原始画面数据{r10,g10,b10}及目标颜色数据{X10',Y10',Z10'}记录在自定义颜色扩充表，如表5所示。For example, please refer to Table 3. This embodiment first obtains the original picture data {r10, g10, b10}. This embodiment determines whether the original picture data {r10, g10, b10} exists in Table 4. It can be seen from Table 4 that Table 4 does not contain the original picture data {r10, g10, b10}. Therefore, this embodiment determines whether the original picture data {r10, g10, b10} exists in Table 4. , calculate the target color data {X10', Y10', Z10'} corresponding to the original picture data {r10, g10, b10}, and combine the original picture data {r10, g10, b10} and the target color data {X10', Y10' ,Z10'} is recorded in the custom color expansion table, as shown in Table 5.
接着，本实施例再获取原始画面数据{r11,g11,b11}。由于原始画面数据{r11,g11,b11}不存在于表4中，因此，本实施例根据插值算法，计算原始画面数据{r11,g11,b11}对应的目标颜色数据{X11',Y11',Z11'}，并将原始画面数据{r11,g11,b11}及目标颜色数据{X11',Y11',Z11'}记录在自定义颜色扩充表中。Next, this embodiment obtains the original picture data {r11, g11, b11}. Since the original picture data {r11, g11, b11} does not exist in Table 4, this embodiment calculates the target color data {X11', Y11', corresponding to the original picture data {r11, g11, b11} according to the interpolation algorithm, Z11'}, and record the original screen data {r11, g11, b11} and the target color data {X11', Y11', Z11'} in the custom color expansion table.
再接着，本实施例再获取原始画面数据{r12,g12,b12}。由于原始画面数据{r12,g12,b12}存在于表4中，因此，本实施例将原始画面数据{r12,g12,b12}及目标颜色数据{X12',Y12',Z12'}记录在自定义颜色扩充表中。以此类推，在此不赘述。通过上述方式，本实施例能够按照原始画面表，在使用者的自定义颜色初始表的基础进行了扩充，从而提高了自定义显示各类RGB配比画面的丰富度。Then, this embodiment obtains the original picture data {r12, g12, b12}. Since the original picture data {r12, g12, b12} exists in Table 4, this embodiment records the original picture data {r12, g12, b12} and the target color data {X12', Y12', Z12'} in Table 4. Define colors in the extension table. By analogy, we will not go into details here. Through the above method, this embodiment can expand the user's customized color initial table according to the original picture table, thereby improving the richness of custom display of various RGB ratio pictures.
如表5所示，对于新增的自定义颜色组合，其会包括原始画面表的原始画面数据，其中，每个原始画面数据在自定义颜色扩充表中都有与之对应的目标颜色数据。举例而言，如前所述，对于自定义颜色组合{r10,g10,b10,X10',Y10',Z10'}，{r10,g10,b10}是原始画面表的原始画面数据，{X10',Y10',Z10'}是自定义颜色扩充表中与{r10,g10,b10}对应的颜色数据，亦即{X10',Y10',Z10'}为目标颜色数据。As shown in Table 5, for the newly added custom color combination, it will include the original picture data of the original picture table, where each original picture data has corresponding target color data in the custom color expansion table. For example, as mentioned before, for the custom color combination {r10,g10,b10,X10',Y10',Z10'}, {r10,g10,b10} is the original picture data of the original picture table, {X10' ,Y10', Z10'} is the color data corresponding to {r10, g10, b10} in the custom color expansion table, that is, {X10', Y10', Z10'} is the target color data.
在一些实施例中，自定义颜色初始表包括初始时多个自定义颜色组合，根据插值算法计算原始画面数据对应的目标颜色数据包括以下步骤：In some embodiments, the custom color initial table includes multiple custom color combinations initially, and calculating the target color data corresponding to the original picture data according to the interpolation algorithm includes the following steps:
S13：确定与原始画面数据相邻的第一自定义画面数据及第二自定义画面数据。S13: Determine the first customized screen data and the second customized screen data adjacent to the original screen data.
S14：确定与第一自定义画面数据对应的第一自定义颜色数据，及与第二自定义画面数据对应的第二自定义颜色数据。S14: Determine the first custom color data corresponding to the first custom picture data and the second custom color data corresponding to the second custom picture data.
S15：根据插值算法、第一自定义颜色数据及第二自定义颜色数据，计算目标颜色数据。S15: Calculate the target color data according to the interpolation algorithm, the first custom color data and the second custom color data.
举例而言，请结合表3与表4，如前所述，原始画面数据{r10,g10,b10}并不存在表4，并且原始画面数据{r10,g10,b10}分别与自定义画面数据{r20,g20,b20}和自定义画面数据{r30,g30,b30}相邻，因此，自定义画面数据{r20,g20,b20}为第一自定义画面数据，自定义画面数据{X20,Y20,Z20}为第一自定义颜色数据。自定义画面数据{r30,g30,b30}为第二自定义画面数据，自定义画面数据{X30,Y30,Z30}为第二自定义颜色数据。本实施例根据插值算法，在第一自定义颜色数据{X20,Y20,Z20}和第二自定义颜色数据{X30,Y30,Z30}之间求取出目标颜色数据{X10',Y10',Z10'}。For example, please combine Table 3 and Table 4. As mentioned above, the original screen data {r10, g10, b10} does not exist in Table 4, and the original screen data {r10, g10, b10} is different from the custom screen data respectively. {r20, g20, b20} is adjacent to the custom screen data {r30, g30, b30}. Therefore, the custom screen data {r20, g20, b20} is the first custom screen data, and the custom screen data {X20, Y20, Z20} is the first custom color data. The custom screen data {r30, g30, b30} is the second custom screen data, and the custom screen data {X30, Y30, Z30} is the second custom color data. In this embodiment, according to the interpolation algorithm, the target color data {X10', Y10', Z10 is obtained between the first custom color data {X20, Y20, Z20} and the second custom color data {X30, Y30, Z30}. '}.
在一些实施例中，颜色校准文件包括颜色校准表，根据自定义颜色扩充表及显示测量数据生成颜色校准文件包括以下步骤：In some embodiments, the color calibration file includes a color calibration table, and generating the color calibration file according to the custom color expansion table and display measurement data includes the following steps:
S16：依序获取每个目标自定义颜色数据，目标自定义颜色数据为自定义颜色扩充表中的一个自定义颜色数据。S16: Obtain each target custom color data in sequence, and the target custom color data is a custom color data in the custom color expansion table.
S17：根据显示测量数据，确定与目标自定义颜色数据匹配的目标系数结构组，目标系数结构组包括目标矩阵系数及目标颜色范围。S17: According to the displayed measurement data, determine the target coefficient structure group that matches the target custom color data.

S19：将目标画面数据替换与目标自定义颜色数据对应的自定义画面数据，得到颜色校准表。S19: Replace the target screen data with the custom screen data corresponding to the target custom color data to obtain a color calibration table.
在S16中，举例而言，请结合表5，首先，本实施例选择自定义颜色数据{X20,Y20,Z20}作为目标自定义颜色数据。在下一次中，本实施例再选择自定义颜色数据{X10',Y10',Z10'}作为目标自定义颜色数据。再在下一次中，本实施例再选择自定义颜色数据{X30,Y30,Z30}作为目标自定义颜色数据，以此类推，在此不赘述。In S16, for example, please refer to Table 5. First, in this embodiment, the custom color data {X20, Y20, Z20} is selected as the target custom color data. The next time, this embodiment selects the custom color data {X10', Y10', Z10'} as the target custom color data. In the next time, this embodiment selects the custom color data {X30, Y30, Z30} as the target custom color data, and so on, which will not be described again here.
在S17中，如前所述，本实施例可采用多种数据形式以表示显示测量数据。当显示测量数据为由预先测量的画面测量数据及颜色测量数据确定的函数关系时，显示测量数据包括多个系数结构组，不同系数结构组的矩阵系数及颜色范围可不同。根据显示测量数据确定与目标自定义颜色数据匹配的目标系数结构组包括以下步骤：In S17, as mentioned above, this embodiment can use a variety of data forms to represent and display the measurement data. When the display measurement data is a functional relationship determined by pre-measured screen measurement data and color measurement data, the display measurement data includes multiple coefficient structure groups, and the matrix coefficients and color ranges of different coefficient structure groups may be different. Determining the target coefficient structure group that matches the target custom color data based on the display measurement data includes the following steps:
S171：根据目标自定义颜色数据，确定目标颜色范围。S171: Determine the target color range based on the target custom color data.
S173：在多个系数结构组中包含目标颜色范围的系数结构组作为目标系数结构组，其中，目标系数结构组还包括与目标颜色范围对应的目标矩阵系数。S173: A coefficient structure group containing the target color range in multiple coefficient structure groups is used as the target coefficient structure group, where the target coefficient structure group also includes a target matrix coefficient corresponding to the target color range.
举例而言，请结合表5，对于目标自定义颜色数据{X20,Y20,Z20}，由于X0≤X20≤X1，Y0≤Y20≤Y1，Z0≤Z20≤Z1，因此，第一段的颜色范围{X0,X1,Y0,Y1,Z0,Z1}为目标颜色范围。由于系数结构组{X0,X1,Y0,Y1,Z0,Z1,b1,b2,b3,b4,b5,b6,b7,b8,b9}包含目标颜色范围{X0,X1,Y0,Y1,Z0,Z1}，因此，系数结构组{X0,X1,Y0,Y1,Z0,Z1,b1,b2,b3,b4,b5,b6,b7,b8,b9}作为目标系数结构组，其中，{b1,b2,b3,b4,b5,b6,b7,b8,b9}为目标矩阵系数。For example, please combine Table 5. For the target custom color data {X20, Y20, Z20}, since X0≤X20≤X1, Y0≤Y20≤Y1, Z0≤Z20≤Z1, therefore, the color range of the first paragraph {X0,X1,Y0,Y1,Z0,Z1} is the target color range. Since the coefficient structure group {X0, Z1}, therefore, the coefficient structure group {X0, b2,b3,b4,b5,b6,b7,b8,b9} are the target matrix coefficients.
同理可得，对于目标自定义颜色数据{X12,Y12,Z12}，由于X6≤X12≤X7，Y6≤Y12≤Y6，Z6≤Z12≤Z7，第四段的颜色范围{X6,X7,Y6,Y7,Z6,Z7}为目标颜色范围。目标系数结构组为：{X6,X7,Y6,Y7,Z6,Z7,b31,b32,b33,b34,b35,b36,b37,b38,b39}。In the same way, for the target custom color data {X12, Y12, Z12}, since X6≤X12≤X7, Y6≤Y12≤Y6, Z6≤Z12≤Z7, the color range of the fourth segment is {X6, ,Y7,Z6,Z7} is the target color range. The target coefficient structure group is: {X6,X7,Y6,Y7,Z6,Z7,b31,b32,b33,b34,b35,b36,b37,b38,b39}.
在一些实施例中，当显示测量数据为测量表时，根据显示测量数据确定与目标自定义颜色数据匹配的目标系数结构组包括以下步骤：In some embodiments, when the display measurement data is a measurement table, determining a target coefficient structure group matching the target custom color data according to the display measurement data includes the following steps:
S172：确定与目标自定义颜色数据匹配的颜色范围作为目标颜色范围。S172: Determine the color range matching the target custom color data as the target color range.
S174：在显示测量数据中，筛选落入目标颜色范围内的颜色测量数据及画面测量数据。S174: In the display measurement data, filter the color measurement data and screen measurement data that fall within the target color range.
S176：根据落入目标颜色范围内的颜色测量数据及画面测量数据，计算目标矩阵系数。S176: Calculate the target matrix coefficient based on the color measurement data and screen measurement data falling within the target color range.
S178：保存目标矩阵系数及目标颜色范围形成的系数结构组作为目标系数结构组。S178: Save the coefficient structure group formed by the target matrix coefficient and the target color range as the target coefficient structure group.
举例而言，请结合表5，对于目标自定义颜色数据{X20,Y20,Z20}，由于X0≤X20≤X1，Y0≤Y20≤Y1，Z0≤Z20≤Z1，因此，第一段的颜色范围{X0,X1,Y0,Y1,Z0,Z1}为目标颜色范围。For example, please combine Table 5. For the target custom color data {X20, Y20, Z20}, since X0≤X20≤X1, Y0≤Y20≤Y1, Z0≤Z20≤Z1, therefore, the color range of the first paragraph {X0,X1,Y0,Y1,Z0,Z1} is the target color range.
接着，本实施例在测量表中，搜索全部落入目标颜色范围{X0,X1,Y0,Y1,Z0,Z1}的颜色测量数据及画面测量数据，然后根据落入目标颜色范围{X0,X1,Y0,Y1,Z0,Z1}内的颜色测量数据及画面测量数据，计算目标矩阵系数。如前所述，本实施例根据最小二乘法，按照公式一，将落入目标颜色范围{X0,X1,Y0,Y1,Z0,Z1}内的多组画面测量数据及颜色测量数据拟合生成目标矩阵系数{b1,b2,b3,b4,b5,b6,b7,b8,b9}。Next, this embodiment searches the measurement table for all color measurement data and screen measurement data that fall into the target color range {X0, ,Y0,Y1,Z0,Z1} color measurement data and screen measurement data, calculate the target matrix coefficient. As mentioned above, this embodiment uses the least squares method and Formula 1 to fit and generate multiple sets of picture measurement data and color measurement data falling within the target color range {X0, X1, Y0, Y1, Z0, Z1}. Target matrix coefficients {b1, b2, b3, b4, b5, b6, b7, b8, b9}.
再次，本实施例将目标矩阵系数及目标颜色范围形成的系数结构组{X0,X1,Y0,Y1,Z0,Z1,b1,b2,b3,b4,b5,b6,b7,b8,b9}作为目标系数结构组。Again, this embodiment uses the coefficient structure group {X0, Target coefficient structure group.
总体而言，本实施例可以将显示测量数据配置为多个系数结构组，并且提前将多个系数结构组进行保存，待后续校准时，直接在多个系数结构组中搜索目标系数结构组。或者，本实施例也可以将显示测量数据配置为测量表，待后续校准时，根据测量表的画面测量数据和颜色测量数据便可生成目标系数结构组。Generally speaking, this embodiment can configure the display measurement data into multiple coefficient structure groups, and save the multiple coefficient structure groups in advance. During subsequent calibration, the target coefficient structure group can be directly searched among the multiple coefficient structure groups. Alternatively, in this embodiment, the displayed measurement data can also be configured as a measurement table. During subsequent calibration, the target coefficient structure group can be generated based on the screen measurement data and color measurement data of the measurement table.
在S18中，本实施例根据公式二计算目标画面数据，如下所示：In S18, this embodiment calculates the target screen data according to Formula 2, as shown below:
公式二的{X,Y,Z}为目标自定义颜色数据，{R',G',B'}为目标画面数据，{bi1,bi2,bi3,bi4,bi5,bi6,bi7,bi8,bi9}为目标矩阵系数。{X,Y,Z} in Formula 2 is the target custom color data, {R',G',B'} is the target screen data, {bi1,bi2,bi3,bi4,bi5,bi6,bi7,bi8,bi9 } is the target matrix coefficient.
举例而言，目标自定义颜色数据{X,Y,Z}为表5的{X20,Y20,Z20}，目标矩阵系数{bi1,bi2,bi3,bi4,bi5,bi6,bi7,bi8,bi9}为{b1,b2,b3,b4,b5,b6,b7,b8,b9}。由公式二可知，得到目标画面数据{R',G',B'}等于{r20',r20',r20'}，并将目标画面数据{r20',r20',r20'}替换目标自定义颜色数据{X20,Y20,Z20}对应的自定义画面数据{r20,g20,b20}，以此类推，可更新表5以生成表6，表6为颜色校准表。For example, the target custom color data {X, Y, Z} is {X20, Y20, Z20} in Table 5, and the target matrix coefficient {bi1, bi2, bi3, bi4, bi5, bi6, bi7, bi8, bi9} is {b1,b2,b3,b4,b5,b6,b7,b8,b9}. It can be seen from formula 2 that the target screen data {R', G', B'} is equal to {r20', r20', r20'}, and the target screen data {r20', r20', r20'} is replaced with the target customization The color data {X20, Y20, Z20} corresponds to the custom screen data {r20, g20, b20}, and so on. Table 5 can be updated to generate Table 6, which is the color calibration table.
表6Table 6
后续，本实施例可根据颜色校准表，控制屏幕显示画面。Subsequently, this embodiment can control the screen display according to the color calibration table.
与上述各个实施例不同点在于，在一些实施例中，颜色自定义数据包括自定义画面系数，显示测量数据包括多组颜色测量组合，每个颜色测量组合包括画面测量数据及与画面测量数据对应的颜色测量数据，根据所述显示测量数据及颜色自定义数据生成颜色校准文件包括以下步骤：The difference from the above embodiments is that in some embodiments, the color customization data includes customized picture coefficients, the display measurement data includes multiple sets of color measurement combinations, and each color measurement combination includes picture measurement data and corresponds to the picture measurement data. Based on the color measurement data, generating a color calibration file based on the display measurement data and color customization data includes the following steps:
S20：根据画面测量数据及自定义画面系数，计算待校准颜色数据。S20: Calculate the color data to be calibrated based on the screen measurement data and customized screen coefficients.
S21：根据待校准颜色数据及与画面测量数据对应的颜色测量数据，计算颜色校准系数。S21: Calculate the color calibration coefficient based on the color data to be calibrated and the color measurement data corresponding to the screen measurement data.
S22：根据颜色校准系数，生成ICC配置文件，其中，ICC配置文件为颜色校准文件。S22: Generate an ICC configuration file according to the color calibration coefficient, where the ICC configuration file is a color calibration file.
在S20中，本实施例根据公式三计算待校准颜色数据，如下所示：In S20, this embodiment calculates the color data to be calibrated according to Formula 3, as shown below:
其中，公式三的{R,G,B}为画面测量数据，自定义画面系数{a1,a2,a3,a4,a5,a6,a7,a8,a9}为使用者自定义的画面系数，{X',Y',Z'}为待校准颜色数据。Among them, {R, G, B} in formula 3 are the screen measurement data, and the custom screen coefficients {a1, a2, a3, a4, a5, a6, a7, a8, a9} are user-defined screen coefficients, { X', Y', Z'} are the color data to be calibrated.
举例而言，本实施例将表1中每个颜色测量组合的画面测量数据及自定义画面系数代入公式三，以计算待校准颜色数据。比如，当画面测量数据RGB为{0,0,0}时，利用公式三，可得到{X1',Y1',Z1'}。当画面测量数据RGB为{32,0,0}时，利用公式三，可得到{X2',Y2',Z2'}。For example, in this embodiment, the picture measurement data and custom picture coefficients of each color measurement combination in Table 1 are substituted into Formula 3 to calculate the color data to be calibrated. For example, when the screen measurement data RGB is {0,0,0}, using formula 3, {X1', Y1', Z1'} can be obtained. When the screen measurement data RGB is {32,0,0}, using formula 3, {X2', Y2', Z2'} can be obtained.
在S21中，本实施例根据公式四计算颜色校准系数，如下所示：In S21, this embodiment calculates the color calibration coefficient according to Formula 4, as shown below:
