[0078] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0079] At present, with the development of display technology, various screens are used in different devices with their unique advantages. For example, the types of screens may include liquid crystal display (LCD) screens and organic light-emitting diode (OLED) screens. LCD screens have a more natural display effect on image information, and OLED screens have a more gorgeous display effect on image information. Electronic devices mostly use LCD screens and OLED screens, and smart home devices mostly use LCD screens. Since electronic devices and smart home devices can be interconnected, smart home devices such as smart gateways, smart TVs, and smart refrigerators can receive and display image information such as photo information and video information transmitted by electronic devices. However, due to different types of screens, the display colors of the same image information in different devices are different. Since different devices have different display colors for the same image information, the display effect of the image information is poor, which affects the user's perception.

[0080] In order to solve the above technical problems, the present disclosure provides a screen color adjustment method to reduce the difference in display colors between different screens. By determining the target color information of the target screen with the reference color coordinates of the reference screen, the image information can be displayed in consistent colors on the target screen and the reference screen, thereby improving the effect of image information display.

[0081] The present disclosure provides a method for adjusting screen color. Figure 1 As shown, the method includes:

[0082] S100. Obtain reference color coordinates of a reference screen.

[0083] S200 , adjusting the color coordinates of the target screen according to the reference color coordinates to obtain target color coordinates.

[0084] S300 , determining target color information of a target screen according to target color coordinates, where the target color information is used to determine a display color of the target screen.

[0085] In this embodiment, by determining the target color information using the reference color coordinates of the reference screen to adjust the display color of the target screen, the image information can be displayed in consistent colors on the target screen and the reference screen, thereby improving the effect of image information display.

[0086] It is understandable that the image information can be displayed in consistent colors on the target screen and the reference screen means that the image information can be displayed in the same or similar colors on the target screen and the reference screen, but not necessarily in exactly the same colors.

[0087] Exemplarily, the reference screen is a screen different from the target screen. For example, when the reference screen is an LCD screen, the target screen may be an OLED screen. When the reference screen is an OLED screen, the target screen may be an LCD screen. It is understandable that the reference screen and the target screen are not limited to LCD screens and OLED screens, but may also be plasma screens, cathode ray tube (CRT) screens, etc. The reference screen refers to a screen used as a reference in the process of adjusting the color information, and its color information does not need to be adjusted, and the target screen refers to a screen whose color information needs to be adjusted. That is, the display color of the target screen is adjusted to be consistent with the display color of the reference screen.

[0088] Exemplarily, the target color information is information used to determine the display color of the target screen, and the target screen can be displayed in a corresponding color according to the target color information. For example, the target color information can be information in a 3D display look-up table (LUT), or information in a color card, etc.

[0089] In one embodiment, the reference color coordinates of the reference screen obtained in step S100 are determined by:

[0090] Get the reference color coordinates of the reference screen when displaying different pure color images.

[0091] In this embodiment, since the image information is displayed in a combination of different colors, when adjusting the display color of the target screen, each color needs to be adjusted. By making the reference screen display different pure color images and obtaining the corresponding reference color coordinates, the color coordinates of each color can be obtained for color adjustment, thereby improving the accuracy of the target screen display color adjustment.

[0092] It is understandable that the embodiment of the present disclosure does not limit the number of pure color images, and the number of pure color images may be, for example, 10, 20, 100, etc.

[0093] In one embodiment, if Figure 2As shown, in step S200, the color coordinates of the target screen are adjusted according to the reference color coordinates, and the target color coordinates are determined in the following manner:

[0094] S210 . Determine, according to the reference color coordinates, the reference color coordinates of the target screen in the first color space.

[0095] S220 , calibrating the reference color coordinates in the second color space to obtain target color coordinates.

[0096] In this embodiment, the reference color coordinates of the target screen in the first color space are determined according to the reference color coordinates, so that the color coordinates of the target screen match those of the reference screen. Since the target screen and the reference screen are different, when the color coordinates match, there is still a difference in the display effect. The reference color coordinates are calibrated in the second color space to reduce the difference in the display effect of the target screen and the reference screen, and the target color coordinates of the target screen are obtained. By calibrating the reference color coordinates determined in the first color space in the second color space, the consistency of the color display of the target screen and the reference screen is enhanced, so as to improve the effect of displaying image information.

[0097] Exemplarily, the first color space and the second color space are different color spaces. The first color space and the second color space may be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0098] In one embodiment, if Figure 3 As shown, in step S210, the reference color coordinates of the target screen in the first color space are determined according to the reference color coordinates by:

[0099] S211, executing the display measurement step.

[0100] S212 . In the same color space, compare the first color coordinates obtained by executing the display measurement step with the reference color coordinates to obtain a first comparison result.

[0101] S213: When the first comparison result meets a preset condition, determine a reference color coordinate according to the first color coordinate.

[0102] S214: When the first comparison result does not meet the preset condition, adjust the reference color coordinates and continue to perform the display measurement step.

[0103] Among them, Figure 4 As shown, the step of executing the display measurement in step S211 is determined by:

[0104] S215: Convert the reference color coordinates into second color coordinates in the third color space.

[0105] S216: Control the target screen to display with the second color coordinates.

[0106] S217, measuring the first color coordinates of the target screen.

[0107] In this embodiment, when determining the reference color coordinates in the first color space, the reference color coordinates are converted into the second color coordinates in the third color space, so that the target screen can be displayed with the second color coordinates. When the target screen is displayed with the second color coordinates, the first color coordinates of the target screen are measured to determine the difference between the first color coordinates displayed on the target screen and the reference color coordinates of the reference screen. In the same color space, the first color coordinates are compared with the reference color coordinates, and a first comparison result is obtained to determine the difference between the first color coordinates and the reference color coordinates. When the first comparison result meets the preset conditions, the difference between the first color coordinates and the reference color coordinates is small, and the reference color coordinates are determined according to the first color coordinates. When the first comparison result does not meet the preset conditions, the difference between the first color coordinates and the reference color coordinates is large, and the target screen cannot meet the requirements of the reference color coordinates. The reference color coordinates are adjusted, and the display measurement step is continued to be performed so that the first color coordinates match the reference color coordinates. By displaying, measuring, comparing and adjusting, a suitable first color coordinate is selected to determine the reference color coordinates, thereby enhancing the consistency of color display between the target screen and the reference screen.

[0108] Exemplarily, the third color space is a color space different from the first color space and the second color space. The third color space may be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0109] Exemplarily, the comparison in step S212 of the first color coordinates obtained by the display measurement step and the reference color coordinates is performed in the same color space. If the first color coordinates and the reference color coordinates are not in the same color space, the first color coordinates can be converted to the color coordinates in the color space where the reference color coordinates are located and then compared, or the reference color coordinates can be converted to the color coordinates in the color space where the first color coordinates are located and then compared. If the first color coordinates and the reference color coordinates are in the same color space, the first color coordinates and the reference color coordinates can be directly compared, or the first color coordinates and the reference color coordinates can be converted to color coordinates in other color spaces except the color space where the first color coordinates and the reference color coordinates are located and then compared. For example, if the first color coordinates are in the XYZ color space and the reference color coordinates are in the Yxy color space, the first color coordinates can be converted to the Yxy color space and then compared with the reference color coordinates. If the first color coordinates are in the XYZ color space and the reference color coordinates are in the Yxy color space, the reference color coordinates can be converted to the XYZ color space and then compared with the first color coordinates. If the first color coordinate and the reference color coordinate are both in the XYZ color space, the first color coordinate and the reference color coordinate may be converted into the Yxy color space and then compared.

[0110] Exemplarily, the comparison in step S212 is performed to display the first color coordinates obtained in the measurement step and the reference color coordinates. The first color coordinates and the reference color coordinates can be respectively subtracted in each dimension to obtain a coordinate difference, or the first color coordinates and the reference color coordinates can be respectively compared in each dimension to obtain a coordinate ratio. For example, the first color coordinates and the reference color coordinates are color coordinates in the Yxy color space, the first color coordinates are (Lv1, x1, y1), and the reference color coordinates are (Lv2, x2, y2). Lv1 is subtracted from Lv2 to obtain △Lv, x1 is subtracted from x2 to obtain △x, and y1 is subtracted from y2 to obtain △y.

[0111] In one embodiment, the reference color coordinates are determined according to the first color coordinates in step S213 by:

[0112] When the first color coordinates are color coordinates in the first color space, the first color coordinates are determined as reference color coordinates.

[0113] When the first color coordinates are color coordinates outside the first color space, the first color coordinates are converted into color coordinates in the first color space as reference color coordinates.

[0114] In this embodiment, when the color coordinates are calibrated in the second color space, the calibrated color coordinates need to be in the first color space. If the first color coordinates are color coordinates in the first color space, the first color coordinates are directly determined as the reference color coordinates. If the first color coordinates are color coordinates outside the first color space, the first color coordinates are converted in the first color space and used as the reference color coordinates. By predetermining the color space where the first color coordinates are located and converting them when necessary, the reference color coordinates are made the color coordinates of the first color space for calibration, thereby improving the reliability of the color coordinate calibration.

[0115] Exemplarily, the adjustment of the reference color coordinates in step S214 may be performed by using the first color coordinates as the reference color coordinates, or by increasing or decreasing the reference color coordinates in each dimension, or by first converting the reference color coordinates into color coordinates in a color space other than the color space where the reference color coordinates are located, and then adjusting or decreasing them, and finally converting them into color coordinates in the color space where the reference color coordinates are located as the adjusted reference color coordinates. For example, the reference color coordinates are color coordinates in the XYZ color space. First, the reference color coordinates are converted into color coordinates in the Yxy color space, and then △Lv1, △x1, and △y1 are added to the coordinates Lv1, x1, and y1 in each dimension, respectively, and finally converted into color coordinates in the XYZ color space as the adjusted reference color coordinates. △Lv1, △x1, and △y1 may be pre-set values, such as △Lv1 is a positive value less than 5, △x1 is a positive value less than 0.001, and △y1 is a positive value less than 0.001. When the reference color coordinates are used to convert the color space, the conversion matrix and the inverse conversion matrix of the color coordinates may be used to implement the conversion. The conversion matrix and the inverse conversion matrix correspond to the color space before and after the conversion of the reference color coordinates.

[0116] In one embodiment, if Figure 5 As shown, the conversion of the reference color coordinates into the second color coordinates in the third color space in step S215 is determined by:

[0117] S2151. Obtain vertex color coordinates of the target screen in the third color space.

[0118] S2152. Determine a color coordinate conversion matrix according to vertex color coordinates.

[0119] S2153: Convert the reference color coordinates using a color coordinate conversion matrix to obtain second color coordinates.

[0120] In this embodiment, the vertex color coordinates of the target screen in the third color space are obtained, and the positions of the vertex color coordinates in the third color space are determined to obtain the color structure of the target screen in the third color space. According to the vertex color coordinates, the color coordinate conversion matrix is ​​determined to convert the reference color coordinates into the second color coordinates. By converting the reference color coordinates by determining the color coordinate conversion matrix with the vertex color coordinates, the accuracy of the reference color coordinates is high, thereby improving the reliability of color coordinate matching.

[0121] Exemplarily, the third color space is an RGB color space, the reference color coordinates are color coordinates in the XYZ color space, the vertex color coordinates are color coordinates of four vertices R, G, B, and W, and the color coordinate conversion matrix is ​​a conversion matrix from the XYZ color space to the RGB color space. After the reference color coordinates are multiplied by the color coordinate conversion matrix, they are converted into the second color coordinates of the RGB color space.

[0122] Exemplarily, in step S216, the target screen is controlled to be displayed with the second color coordinates, a polynomial color correction (PCC) matrix may be generated according to the second color coordinates, and then displayed on the target screen through the PCC matrix.

[0123] In one embodiment, the first comparison result includes the coordinate difference between the first color coordinate and the reference color coordinate in each dimension. The preset condition includes that each coordinate difference is less than a preset limit value of the dimension.

[0124] In this embodiment, the first comparison result includes the coordinate difference between the first color coordinate and the reference color coordinate in each dimension, and the preset condition includes that each coordinate difference is less than the preset limit of the dimension, so that the first comparison result converges to the preset limit. Since the preset condition is that each coordinate difference is less than the preset limit of the dimension, the first color coordinate and the reference color coordinate are matched because they are the same or close, thereby improving the reliability of color coordinate matching.

[0125] Exemplarily, the first comparison result includes coordinate differences △Lv1, △x1, △y1 of each dimension, and the preset limits of each dimension include 5, 0.001, 0.001. Then the preset conditions include △Lv1 less than 5, △x1 less than 0.001 and △y1 less than 0.001.

[0126] In one embodiment, if Figure 6 As shown, in step S220, the reference color coordinates are calibrated in the second color space, and the target color coordinates are determined by:

[0127] S221 . Convert the reference color coordinates into third color coordinates in the second color space.

[0128] S222: Obtain display effect information of the reference screen and the target screen.

[0129] S223: Compare the display effect information of the reference screen and the target screen to obtain a second comparison result.

[0130] S224. Calibrate the third color coordinates according to the second comparison result to obtain target color coordinates of the target screen in a fourth color space.

[0131] In this embodiment, when the reference color coordinates match the reference color coordinates, there is still a certain difference in the display colors of the target screen and the reference screen, and the reference color coordinates of the target screen need to be calibrated. The reference color coordinates are converted into third color coordinates in the second color space to facilitate the adjustment of color differences. The display effect information of the reference screen and the target screen is obtained and compared to obtain a second comparison result reflecting the difference in display effect information. According to the second comparison result, the third color coordinates are calibrated to reduce the difference in color display between the reference screen and the target screen. The target color coordinates of the target screen in the fourth color space are obtained by calibration to determine the target color information of the target screen so that the display colors of the target screen are consistent with those of the reference screen, thereby improving the effect of image information display.

[0132] Exemplarily, the first color space is an XYZ color space, the second color space is a Lab color space, and the conversion of the reference color coordinates into the third color coordinates in the second color space in step S221 is determined by:

[0133]

[0134] Among them, L, a, b are the third color coordinates in the Lab color space, p 00 、p 01 、p 02 、p 10 、p 11 、p 12 、p 20 、p 21 and p 22 are the coefficients in the conversion matrix from XYZ color space to Lab color space, and X, Y, and Z are the reference color coordinates in the XYZ color space.

[0135] Exemplarily, the display effect information is used to reflect the effect of color display, including brightness, color difference, etc. Since when the base color coordinates match the reference color coordinates, there are still certain differences in the display effect information of the reference screen and the target screen observed by the user. In order to reduce the impact of the difference in the display effect information on the user, the third color coordinate is calibrated, and a pre-trained calibration neural network model can be used for calibration. The calibration neural network model can be trained with a large amount of image information given by the user, and automatically calibrates the third color coordinate.

[0136] Exemplarily, the fourth color space is a color space different from the first color space, the second color space and the third color space. The fourth color space may be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0137] Exemplarily, in step S224, the third color coordinates are calibrated according to the second comparison result to obtain the target color coordinates of the target screen in the fourth color space. After the calibration of the third color coordinates is completed, the third color coordinates are the color coordinates in the second color space. When obtaining the target color coordinates of the target screen in the fourth color space, it can be obtained by a conversion matrix from the second color space to the fourth color space, or by a conversion matrix from the second color space to the first color space and a conversion matrix from the first color space to the fourth color space, or by measuring the target color coordinates of the target screen in the fourth color space.

[0138] In one embodiment, if Figure 7 As shown, in step S300, the target color information of the target screen is determined according to the target color coordinates in the following manner:

[0139] S310 , obtaining fourth color coordinates of the reference screen in a fourth color space.

[0140] S320 , determining a compensation color coordinate according to the target color coordinate and the fourth color coordinate.

[0141] S330 , determining target color information according to the target color coordinates and the compensation color coordinates.

[0142] In this embodiment, since the target color coordinates are determined when the display effects of the reference screen and the target screen are consistent, the fourth color coordinates of the reference screen in the fourth color space are obtained to determine the difference between the target color coordinates and the fourth color coordinates in the fourth color space. According to the target color coordinates and the fourth color coordinates, the compensation color coordinates as the difference are determined, and the target color information is determined according to the target color coordinates and the compensation color coordinates. By determining the target color information with the target color coordinates and the compensation color coordinates to adjust the display color of the target screen, the display colors of the target screen and the reference screen are made consistent, thereby improving the effect of displaying the image information.

[0143] Exemplarily, obtaining the fourth color coordinates of the reference screen in the fourth color space in step S310 can be obtained by measuring the fourth color coordinates of the reference screen in the fourth color space, or by converting the reference color coordinates through a conversion matrix from the color space where the reference color coordinates are located to the fourth color space.

[0144] Exemplarily, in step S320, the compensation color coordinates are determined according to the target color coordinates and the fourth color coordinates, and the difference between the target color coordinates and the fourth color coordinates in each dimension can be used as the compensation color coordinates. For example, the fourth color space is a YUV color space, and without considering the brightness, the target color coordinates are (U1, V1), and the fourth color coordinates are (U0, V0). The difference between the target color coordinates and the fourth color coordinates in each dimension is △U=U1-U0, △V=V1-V0, and the compensation color coordinates are (△U, △V).

[0145] In one embodiment, if Figure 8 As shown, in step S330, the target color information is determined according to the target color coordinates and the compensation color coordinates in the following manner:

[0146] S331. Obtain reference color information of a reference screen.

[0147] S332. Determine, according to the reference color information, a fifth color coordinate whose distance from the target color coordinate in the fourth color space is within a preset threshold range.

[0148] S333 , compensating the fifth color coordinates with the compensation color coordinates to obtain sixth color coordinates.

[0149] S334. Determine target color information according to the sixth color coordinates.

[0150] In this embodiment, the reference color information of the reference screen is obtained as a basis for determining the target color information. Since the reference color information includes multiple color coordinates in the fourth color space, the fifth color coordinate whose distance from the target color coordinate in the fourth color space is within the preset threshold range is determined, and the fifth color coordinate and the target color coordinate are the corresponding color coordinates in the reference screen and the target screen. If the target color information is determined directly based on the fifth color coordinate, there will be a difference in the display color between the target screen and the reference screen. The sixth color coordinate is obtained by compensating the fifth color coordinate with the compensation color coordinate, and the target color information is determined based on the sixth color coordinate. By finding the fifth color coordinate corresponding to the target color coordinate and compensating it, the difference in color display between the target screen and the reference screen is reduced, thereby improving the effect of image information display.

[0151] Exemplarily, the reference color information is information used to determine the display color of the reference screen. The step of acquiring the reference color information of the reference screen in step S331 may be acquiring information of the reference screen in the 3D LUT.

[0152] Exemplarily, in step S332, according to the reference color information, the fifth color coordinate whose distance from the target color coordinate in the fourth color space is within the preset threshold range is determined, and the reference color information can be converted into the color coordinate in the fourth color space, and then the color coordinate whose distance from the target color coordinate is within the preset threshold range is determined as the fifth color coordinate. That is, the number of the fifth color coordinates can be multiple. For example, the reference color information is the information of the reference screen in the 3D LUT, and each RGB node in the 3D LUT can be converted into the color coordinate in the fourth color space under the P3 color gamut, and then the color coordinate whose distance from the target color coordinate is within the preset threshold range is determined as the fifth color coordinate. The preset threshold range can be determined according to the accuracy of the reference color information. The higher the accuracy of the reference color information, the smaller the preset threshold. The lower the accuracy of the reference color information, the larger the preset threshold. For example, the preset threshold can be 1.5 times, 2 times, 3 times, etc., of the distance between two adjacent RGB nodes in the 3D LUT.

[0153] For example, in addition to determining the fifth color coordinates whose distance from the target color coordinates in the fourth color space is within the preset threshold range according to the reference color information in step S332, the fifth color coordinates whose distance from the target color coordinates in the fourth color space is the smallest can also be determined according to the reference color information. For example, the fourth color space is a YUV color space, and without considering the brightness, the target color coordinates are (U1, V1), and the fifth color coordinates are (U2, V2), then Among them, s min Indicates the minimum distance between the color coordinates of the reference color information converted into the YUV color space and the target color coordinates.

[0154] Exemplarily, in step S333, the fifth color coordinate is compensated by the compensation color coordinate to obtain the sixth color coordinate, and the coordinates of the fifth color coordinate and the compensation color coordinate in each dimension can be summed as the sixth color coordinate. For example, if the fourth color space is a YUV color space, the fifth color coordinate is (U2, V2), and the compensation color coordinate is (△U, △V), then the sixth color coordinate is (U2+△U, V2+△V).

[0155] Exemplarily, in S334, the target color information is determined according to the sixth color coordinates, and the sixth color coordinates can be converted into RGB nodes in the 3D LUT as the target color information. Since the reference color coordinates are obtained when the reference screen displays different pure color images, there are multiple sixth color coordinates, which can constitute each RGB node in the 3D LUT.

[0156] In one embodiment, after determining the target color information of the target screen according to the target color coordinates in step S300, the screen color adjustment method further includes:

[0157] Write the target color information to the device where the target screen is located.

[0158] In this embodiment, by writing the target color information into the device where the target screen is located, the target screen can be displayed with the adjusted color to achieve consistency with the color display of the reference screen, thereby improving the effect of image information display.

[0159] Exemplarily, before the target color information is written into the target screen, the device where the target screen is located may have initial color information, and the target color information is used to adjust or overwrite the initial color information; the device where the target screen is located may also not contain the initial color information, and the target color information is directly written into the device where the target screen is located.

[0177] In this embodiment, the reference color coordinates of the reference screen when displaying different pure color images are obtained, the display measurement step is performed on the target screen, and the difference between the measured first color coordinates and the reference color coordinates is compared. When the first color coordinates match the reference color coordinates, the reference color coordinates are determined according to the first color coordinates. When the first color coordinates do not match the reference color coordinates, the reference color coordinates are adjusted. The reference color coordinates are converted into third color coordinates in the second color space, and the display effect information of the reference screen and the target screen is obtained and compared to obtain a second comparison result. According to the second comparison result, the third color coordinates are calibrated so that the color display of the target screen is consistent with that of the reference screen. The fourth color coordinates of the reference screen in the fourth color space are obtained, and the compensation color coordinates are determined according to the target color coordinates and the fourth color coordinates. The fifth color coordinates whose distance from the target color coordinates is within a preset threshold range are compensated by the compensation color coordinates, and the target color information is determined according to the obtained sixth color coordinates, and the target color information is written into the device where the target screen is located. By determining the target color information with the reference color coordinates of the reference screen to adjust the display color of the target screen, the image information can be displayed in a consistent color on the target screen and the reference screen, thereby improving the effect of image information display.

[0178] Exemplarily, the first color space is an XYZ color space, the second color space is a Lab color space, the third color space is an RGB color space, the fourth color space is a YUV color space, the reference color information is the information of the reference screen in the 3D LUT, and the target color information is the information of the target screen in the 3D LUT. Obtain the reference color coordinates of the XYZ color space when the reference screen displays different pure color images. Obtain the vertex color coordinates of the target screen in the RGB color space, and determine the color coordinate conversion matrix according to the vertex color coordinates. After multiplying the reference color coordinates with the color coordinate conversion matrix, they are converted into the second color coordinates of the RGB color space, and the color coordinate conversion matrix is ​​the conversion matrix from the XYZ color space to the RGB color space. Generate a PCC matrix according to the second color coordinates, and display it on the target screen through the PCC matrix. Measure the first color coordinates of the target screen in the XYZ color space. Convert the first color coordinates and the reference color coordinates into color coordinates in the Yxy color space and compare them to obtain the first comparison results △Lv, △x and △y. When the absolute value of △Lv is less than 5, the absolute value of △x is less than 0.001, and the absolute value of △y is less than 0.001, the first color coordinate is determined as the reference color coordinate. Otherwise, the reference color coordinate is converted into the color coordinate in the Yxy color space and adjusted, and converted into the color coordinate in the XYZ color space as the adjusted reference color coordinate, and the display measurement step is performed again until the reference color coordinate is determined. The reference color coordinate is converted into the third color coordinate in the Lab color space. The display effect information of the reference screen and the target screen is obtained and compared to obtain a second comparison result. The third color coordinate is calibrated according to the second comparison result, and the calibrated color coordinate is converted into the target color coordinate in the YUV color space. The fourth color coordinate of the reference screen in the YUV color space is obtained. The difference between the target color coordinate and the fourth color coordinate in each dimension is determined as the compensation color coordinate. The information of the reference screen in the 3D LUT is obtained. Each RGB node of the reference screen in the 3D LUT is converted into the color coordinate in the YUV color space under the P3 color gamut, and the fifth color coordinate with the smallest distance from the target color coordinate is determined.
