[0008] If the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed includes a first color located in the first color gamut space, the first color corresponding to the second color display mode is converted into a second color corresponding to the first color display mode according to the first color conversion matrix, and the second color is enhanced according to the first color enhancement matrix.

[0012] a first processing module, configured to enhance the color of the content to be displayed according to a first color enhancement matrix if the color display mode of the electronic device is the first color display mode and the color gamut space where the color of the content to be displayed is located is the first color gamut space;

[0013] A second processing module is used to convert the first color corresponding to the second color display mode into the second color corresponding to the first color display mode according to the first color conversion matrix if the color display mode of the electronic device is the second color display mode and the color of the content to be displayed includes the first color located in the first color gamut space, and enhance the second color according to the first color enhancement matrix.

The embodiment of the present application can obtain the color gamut space where the color of the content to be displayed is located. If the color display mode of the electronic device is the first color display mode, and the color gamut space where the color of the content to be displayed is located is the first color gamut space, the color of the content to be displayed is enhanced according to the first color enhancement matrix, so that the color of the content to be displayed can be mapped from the first color gamut space to a larger color gamut space, so that the display screen of the electronic device can display colors beyond the first color gamut space when displaying the content to be displayed, and the color of the content to be displayed displayed on the display screen of the electronic device is more vivid, thereby improving the display effect of the electronic device. If the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed includes the first color located in the first color gamut space, the embodiment of the present application takes into account that when the color display mode of the electronic device is different, the display effect of the color in the first color gamut space is different. If the first color is directly enhanced, the color display effect of the first color after the enhancement is also inconsistent under different color display modes.

The display effect is consistent or close to the display effect of displaying the first color when the color display mode of the electronic device is the first color display mode, and then the second color is mapped from the first color gamut space to the larger color gamut space through the first color enhancement matrix, so that the display screen of the electronic device displays the content to be displayed with brighter colors, thereby improving the display effect of the electronic device, and whether the color display mode of the electronic device is the first color display mode or the second color display mode, when displaying the content to be displayed whose color is located in the first color gamut space or the first color in the content to be displayed that is located in the first color gamut space, the display screen of the electronic device can maintain a consistent or close color display effect, thereby improving the user experience. Therefore, when the user uses the electronic device, the color in the content to be displayed that is located in the first color gamut space will not have different display effects due to the switching of different color display modes, thereby improving the user experience.

[0024] Please refer to the drawings, where the same component symbols represent the same components. The principle of the present application is illustrated by implementing it in an appropriate computing environment. The following description is based on the illustrated specific embodiments of the present application, which should not be considered as limiting other specific embodiments of the present application that are not described in detail herein.

[0025] It is understandable that the execution subject of the embodiments of the present application may be an electronic device such as a smart phone, a tablet computer, a television, etc.

[0026] See also Figure 1 , Figure 1 : is a flow chart of a color processing method provided in an embodiment of the present application. The color processing method can be applied to electronic devices. The process of the color processing method may include:

[0027] In 101, a color display mode of an electronic device is obtained, where the color display mode includes at least a first color display mode and a second color display mode, where the first color display mode supports displaying colors in a first color gamut space, and the second color display mode supports displaying colors in a second color gamut space, where the first color gamut space is smaller than the second color gamut space;

[0028] In 102, the color gamut space of the color of the content to be displayed is obtained;

[0029] In 103, if the color display mode of the electronic device is the first color display mode, and the color gamut space where the color of the content to be displayed is located is the first color gamut space, the color of the content to be displayed is enhanced according to the first color enhancement matrix;

[0030] In 104, if the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed includes a first color located in the first color gamut space, the first color corresponding to the second color display mode is converted into a second color corresponding to the first color display mode according to the first color conversion matrix, and the second color is enhanced according to the first color enhancement matrix.

[0031] With the continuous development of technology, electronic devices can support different color display modes, wherein electronic devices can automatically switch between different color display modes according to different usage scenarios, and electronic devices can also respond to user mode switching instructions to switch between different color display modes, wherein different color display modes can support the display of colors in different color gamut spaces. When electronic devices display the same content to be displayed in different color display modes, the displayed colors are inconsistent, resulting in different display effects.

[0032] The embodiment of the present application can obtain the current color display mode of the electronic device. The color display modes supported by the electronic device include at least a first color display mode and a second color display mode. The first color display mode supports displaying colors in a first color gamut space, and the second color display mode supports displaying colors in a second color gamut space. The first color gamut space is smaller than the second color gamut space. Exemplarily, the first color display mode is, for example, an sRGB color display mode, and the second color display mode is, for example, a DCI-P3 color display mode. When the current color display mode of the electronic device is an sRGB color display mode, it can be considered that the display screen of the electronic device is displayed according to the sRGB color gamut standard. When the current color display mode of the electronic device is a DCI-P3 color display mode, it can be considered that the display screen of the electronic device is displayed according to the DCI-P3 color gamut standard. Since the second color gamut space supported by the DCI-P3 color gamut standard is larger than the first color gamut space supported by the sRGB color gamut standard, the second color gamut space supported by the DCI-P3 color display mode has a wider color gamut space than the first color gamut space supported by the sRGB color display mode. It can also be considered that the second color gamut space covers the first color gamut space. Therefore, when the current color display mode of the electronic device is the DCI-P3 color display mode, the electronic device can present more colors. It should be noted that the embodiments of the present application do not limit specific color display modes, such as the Adobe RGB color display mode, the BT2020 standard, etc. The following content is described by taking the first color display mode, such as the sRGB color display mode, and the second color display mode, such as the DCI-P3 color display mode, as an example.

[0033] The embodiment of the present application can obtain the color gamut space where the color of the content to be displayed is located. It can be understood that the color of the content to be displayed, such as an image, is encoded by a specific color gamut standard. For example, if the color of the content to be displayed is encoded by the sRGB color gamut standard, then the color gamut space where the color of the content to be displayed is the first color gamut space corresponding to the sRGB color gamut standard. If the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, then the color gamut space where the color of the content to be displayed is the second color gamut space corresponding to the sRGB color gamut standard.

[0034] If the color display mode of the electronic device is the first color display mode, and the color gamut space where the color of the content to be displayed is located is the first color gamut space, the color of the content to be displayed is enhanced according to the first color enhancement matrix.

[0035] Exemplarily, if the color display mode of the electronic device is the sRGB color display mode, and the color of the content to be displayed is encoded by the sRGB color gamut standard, then the color gamut space where the color of the content to be displayed is located is the first color gamut space, and the display screen of the electronic device can normally display the color of the content to be displayed.

[0036] It is understandable that the color gamut space that the display screen of the current electronic device can display has exceeded the color gamut space that the color display mode can support, such as exceeding the color gamut space that the sRGB color display mode or the DCI-P3 color display mode can support, that is, the display screen can be used to display colors that exceed the first color gamut space and the second color gamut space. The embodiment of the present application takes into account the increasing requirements of users for the display effect of the display screen. If the display screen of the electronic device is only used to display colors in the first color gamut space, the color display of the display screen is relatively pale, the colors are not rich enough, and the colors are not bright enough, which affects the display effect.

[0037] Therefore, the embodiment of the present application obtains a first color enhancement matrix, and enhances the color of the content to be displayed according to the first color enhancement matrix, so that the color of the content to be displayed can be mapped from the first color gamut space to a larger color gamut space, so that the display screen of the electronic device can display colors beyond the first color gamut space when displaying the content to be displayed, so that the color of the content to be displayed displayed through the display screen of the electronic device is richer and more vivid, thereby improving the display effect of the electronic device.

[0038] If the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed includes a first color located in the first color gamut space, the first color corresponding to the second color display mode is converted into the second color corresponding to the first color display mode according to the first color conversion matrix, and the second color is enhanced according to the first color enhancement matrix.

[0039] The embodiments of the present application take into account that when the color display mode of the electronic device is different, the display effect of the first color in the first color gamut space is different. For example, when the color display mode is DCI-P3 color display mode and the first color of the content to be displayed is displayed when the color display mode is sRGB color display mode, the color display effects of the two are different. If the first color is directly enhanced, then when the electronic device switches to different color display modes, the color display effect of the first color after the enhancement processing is also inconsistent.

[0040] For example, the color display mode of the electronic device is the DCI-P3 color display mode, the color of the content to be displayed is encoded by the sRGB color gamut standard, and the color of the content to be displayed is the first color located in the first color gamut space. For another example, the color display mode of the electronic device is the DCI-P3 color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, so the color gamut space where the color of the content to be displayed is located is the second color gamut space, wherein the second color gamut space is larger than the first color gamut space, and it can also be understood that the second color gamut space covers the second color gamut space, therefore, the color of the content to be displayed may include the first color located in the first color gamut space and the third color located in the first color gamut space and the second color gamut space.

[0041] It can be understood that for the content to be displayed, such as image 1, the colors in image 1 are all distributed in the first color gamut space, and image 1 is displayed when the color display mode is the DCI-P3 color display mode, and the color display effect displayed on the display screen is different when the color display mode is the sRGB color display mode. For another example, for the content to be displayed, such as image 2, the first color in image 2 is distributed in the first color gamut space, and the first color of the content to be displayed is displayed when the color display mode is the DCI-P3 color display mode, and the color display effect displayed on the display screen is different when the color display mode is the sRGB color display mode. The embodiment of the present application takes into account that if the first color of image 1 or image 2 is directly enhanced, then when the electronic device switches to different color display modes, the first color display effects of image 1 and image 2 after the enhanced processing are also inconsistent.

[0042] Exemplarily, the electronic device can switch the current color display mode to the DCI-P3 color display mode or the SRGB color display mode according to different usage scenarios. For example, when the electronic device is running different applications, it may automatically switch to different color display modes. For example, when running the first application, the electronic device can switch to the DCI-P3 color display mode, and when running the second application, the electronic device can switch to the SRGB color display mode. If the user calls up image 1 or image 2 for display when running the first application or the second application, then for the same image 1, the color display effect of image 1 or image 2 seen by the user in the first application is different from the color display effect of image 1 or image 2 seen in the second application, resulting in inconsistent display effects of the electronic device in different usage scenarios for the same content to be displayed, which can easily cause user confusion about the display effect and affect the user's usage experience.

[0043] Therefore, the first color corresponding to the second color display mode is first converted into the second color corresponding to the first color display mode according to the first color conversion matrix, and then the second color is enhanced according to the first color enhancement matrix. Exemplarily, after obtaining the first color conversion matrix and the first color enhancement matrix, the first color can be converted according to the first color conversion matrix to obtain the converted second color, and then the second color can be enhanced according to the first color enhancement matrix to obtain the enhanced second color, and the display screen displays according to the enhanced second color. In another example, the first color enhancement matrix can also be multiplied by the first color conversion matrix to obtain a target color enhancement matrix, and then the first color can be enhanced according to the target color enhancement matrix.

[0044] Among them, the first color of the content to be displayed is converted into the second color through the first color conversion matrix, so that when the color display mode of the electronic device is the second color display mode, the display effect of the second color is displayed, which is consistent or close to the display effect of the first color when the color display mode of the electronic device is the first color display mode. The second color is mapped from the first color gamut space to the larger color gamut space through the first color enhancement matrix, so that when the display screen of the electronic device displays the content to be displayed, the color displayed is more vivid, thereby improving the display effect of the electronic device. Moreover, regardless of whether the color display mode of the electronic device is the first color display mode or the second color display mode, when displaying the content to be displayed whose color is located in the first color gamut space or the first color in the content to be displayed that is located in the first color gamut space, the display screen of the electronic device can maintain a consistent or close color display effect, thereby improving the user experience. Therefore, when the user uses the electronic device, the color of the first color gamut space in the content to be displayed will not have different display effects due to the switching of different color display modes, thereby improving the user experience.

[0045] See also Figure 2 , Figure 2 Another schematic diagram of a color processing method provided in an embodiment of the present application, the process may include:

[0046] In 201, a color display mode of the electronic device is obtained, the color display mode includes at least a first color display mode and a second color display mode, the first color display mode supports displaying colors in a first color gamut space, the second color display mode supports displaying colors in a second color gamut space, and the first color gamut space is smaller than the second color gamut space.

[0047] The embodiment of the present application can obtain the current color display mode of the electronic device, and the color display mode supported by the electronic device includes at least a first color display mode and a second color display mode. The first color display mode supports the display of the color of the first color gamut space, and the second color display mode supports the display of the color of the second color gamut space, and the first color gamut space is smaller than the second color gamut space. Exemplarily, the first color display mode is such as the sRGB color display mode, and the second color display mode is such as the DCI-P3 color display mode. When the current color display mode of the electronic device is the sRGB color display mode, it can be considered that the display screen of the electronic device is displayed according to the sRGB color gamut standard, and when the current color display mode of the electronic device is the DCI-P3 color display mode, it can be considered that the display screen of the electronic device is displayed according to the DCI-P3 color gamut standard. Since the second color gamut space supported by the DCI-P3 color gamut standard is larger than the first color gamut space supported by the sRGB color gamut standard, the second color gamut space supported by the DCI-P3 color display mode has a wider color gamut space than the first color gamut space supported by the sRGB color display mode.

[0048] In 202, the color gamut space of the color of the content to be displayed is obtained.

[0049] The embodiment of the present application can obtain the color gamut space where the color of the content to be displayed is located. It can be understood that the color of the content to be displayed, such as an image, is encoded by a specific color gamut standard. For example, if the color of the content to be displayed is encoded by the sRGB color gamut standard, then the color gamut space where the color of the content to be displayed is the first color gamut space corresponding to the sRGB color gamut standard. If the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, then the color gamut space where the color of the content to be displayed is the second color gamut space corresponding to the sRGB color gamut standard.

[0050] In 203, if the color display mode of the electronic device is the first color display mode, and the color gamut space where the color of the content to be displayed is located is the first color gamut space, a third color gamut space is set, the third color gamut space is smaller than the second color gamut space and larger than the first color gamut space, and a first color enhancement matrix that maps the first color gamut space to the third color gamut space is obtained;

[0051] In 204, the color of the content to be displayed is enhanced according to the first color enhancement matrix.

[0052] In one embodiment, the color display mode of the electronic device is the sRGB color display mode, and the color of the content to be displayed is encoded by the sRGB color gamut standard, then the color gamut space where the color of the content to be displayed is located is the first color gamut space, and the display screen of the electronic device can normally display the color to be displayed in the first color gamut space.

[0053] It is understandable that the color gamut space that can be displayed by the display screen of the current electronic device has exceeded the color gamut space that can be supported by the color display mode, such as exceeding the color gamut space that can be supported by the sRGB color display mode or the DCI-P3 color display mode, that is, the display screen can be used to display colors that exceed the first color gamut space and the second color gamut space. The embodiment of the present application takes into account the increasing requirements of users for the display effect of the display screen. If the display screen of the electronic device is only used to display colors in the first color gamut space, the color display of the display screen is relatively pale, the colors are not rich enough, and the colors are not bright enough, which affects the display effect.

[0054] Therefore, the embodiment of the present application can set a third color gamut space, which is smaller than the second color gamut space and larger than the first color gamut space. It can also be understood that the second color gamut space contains the third color gamut space, and the third color gamut space contains the first color gamut space. Please refer to Figure 3 , Figure 3 : is a schematic diagram of the distribution of different color gamut spaces provided in the embodiment of the present application. The color gamut space included in L1 is the first color gamut space corresponding to the sRGB color gamut standard, the color gamut space included in L2 is the second color gamut space corresponding to the DCI-P3 color gamut standard, and the color gamut space included in L3 can be the third color gamut space. It can be understood that the display screen has a native maximum color gamut space. For example, the color gamut space included in L5 in the figure is the largest color gamut space of the display screen, and the largest color gamut space of the display screen is larger than the first color gamut space and also larger than the second color gamut space.

[0055] A first color enhancement matrix that maps the first color gamut space to the third color gamut space is obtained, and the color of the content to be displayed is enhanced according to the first color enhancement matrix, so that the color of the content to be displayed can be mapped from the first color gamut space to the third color gamut space. When displaying the content to be displayed, the display screen of the electronic device can display the color of the third color gamut space, which exceeds the color of the first color gamut space, so that the colors displayed on the display screen of the electronic device are richer and more vivid, thereby improving the display effect of the electronic device.

[0056] Exemplarily, the first color enhancement matrix M (sRGBEnhance2Panel) is obtained as follows:

[0057] It can be understood that the display screen has a native maximum color gamut space and can support the display of colors in the maximum color gamut space. Different color gamut spaces have corresponding RGB three-primary color vertices, and different color gamut spaces can be represented by triangular areas composed of corresponding RGB three-primary color vertices. For example, the corresponding RGB vertex coordinates of the maximum color gamut space, the first color gamut space, the second color gamut space, and the third color gamut space of the display screen are shown in Table 1:

[0058] Table 1:

[0059]

[0060] 1.1, the three vertex coordinates of the third color gamut space are combined into a matrix M (TargetColor), and M (Target) is calculated. Through M (Target), the RGB data can be converted to the XYZ space.

[0061] Specifically, the calculation process of M(Target) is as follows:

[0062] For example, R1(0.655,0.328), G1(0.288,0.641), B1(0.1500,0.060).

[0063] First calculate xr , yr; xg , yg;xb,yb;xw , yw:

[0064] xr=R1x;

[0065] yr=R1y;

[0066] xg=G1x;

[0067] yg=G1y;

[0068] xb=B1x;

[0069] yb=B1y;

[0070] xw=W1x;

[0071] yw=W1y;

[0072] Where W1 is the coordinate of the white point in the third color gamut space.

[0073] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0074] Xr=xr / yr; Xg=xg / yg;

[0075] Yr=1; Yg=1;

[0076] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0077] Xb=xb / yb; Xw=xw / yw;

[0078] Yb=1; Yw=1;

[0079] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0080] Then calculate the temporary matrix M (XYZ_Matrix):

[0081]

[0082] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0083]

[0084] The matrix M(Target) is calculated:

[0085]

[0086] 1.2, a matrix M(PanelColor) is formed by the three vertex coordinates of the maximum color gamut space that the display can display, and M(Panel) is calculated. Through M(Panel), RGB data can be converted to XYZ space.

[0087]

[0088] First calculate xr, yr; xg, yg; xb, yb; xw, yw:

[0089] xr=R2x;

[0090] yr=R2y;

[0091] xg=G2x;

[0092] yg=G2y;

[0093] xb=B2x;

[0094] yb=B2y;

[0095] xw=W2x;

[0096] yw=W2y;

[0097] Where W2 is the coordinate of the white point of the maximum color gamut space of the display screen. It can be understood that the white point coordinates of each display screen are also different.

[0098] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0099] Xr=xr / yr; Xg=xg / yg;

[0100] Yr=1; Yg=1;

[0101] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0102] Xb=xb / yb; Xw=xw / yw;

[0103] Yb=1; Yw=1;

[0104] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0105] Then calculate the temporary matrix M (XYZ_Matrix):

[0106]

[0107] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0108]

[0109] The matrix M(Panel) is calculated:

[0110]

[0111] Calculate the inverse matrix M(InversePanel) of M(Panel);

[0112] Thus, the first color enhancement matrix M(sRGBEnhance2Panel)=M(InversePanel)*M(Target) is calculated.

[0113] After obtaining the first color enhancement matrix, the embodiment of the present application performs enhancement processing on the color of the content to be displayed according to the first color enhancement matrix. Specifically, the three-primary color data of the color in the content to be displayed is normalized to obtain normalized three-primary color data; the normalized three-primary color data is linearized to obtain linearized data; the linearized data is enhanced according to the first color enhancement matrix to obtain enhanced data; the enhanced data is inversely linearized to obtain inversely linearized data; the inversely linearized data is inversely normalized to obtain the three-primary color data after the color in the content to be displayed is enhanced.

[0114] In 205, if the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed includes a first color located in the first color gamut space, the first color corresponding to the second color display mode is converted into the second color corresponding to the first color display mode according to the first color conversion matrix.

[0115] In 206, the second color is enhanced according to the first color enhancement matrix.

[0116] The embodiments of the present application take into account that when the color display mode of the electronic device is different, the display effect of the first color in the first color gamut space is different. For example, when the color display mode is DCI-P3 color display mode and the first color of the content to be displayed is displayed when the color display mode is sRGB color display mode, the color display effects of the two are different. If the first color is directly enhanced, then when the electronic device switches to different color display modes, the color display effect of the first color after the enhancement processing is also inconsistent.

[0117] For example, the color display mode of the electronic device is the DCI-P3 color display mode, the color of the content to be displayed is encoded by the sRGB color gamut standard, and the color of the content to be displayed is the first color located in the first color gamut space. For another example, the color display mode of the electronic device is the DCI-P3 color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, so the color gamut space where the color of the content to be displayed is located is the second color gamut space, wherein the second color gamut space is larger than the first color gamut space, and it can also be understood that the second color gamut space covers the second color gamut space, therefore, the color of the content to be displayed may include the first color located in the first color gamut space and the third color located in the first color gamut space and the second color gamut space.

[0118] It can be understood that for the content to be displayed, such as image 1, the colors in image 1 are all distributed in the first color gamut space, and image 1 is displayed when the color display mode is the DCI-P3 color display mode, and the color display effect displayed on the display screen is different when the color display mode is the sRGB color display mode. For another example, for the content to be displayed, such as image 2, the first color in image 2 is distributed in the first color gamut space, and the first color of the content to be displayed is displayed when the color display mode is the DCI-P3 color display mode, and the color display effect displayed on the display screen is different when the color display mode is the sRGB color display mode. The embodiment of the present application takes into account that if the first color of image 1 or image 2 is directly enhanced, then when the electronic device switches to different color display modes, the first color display effects of image 1 and image 2 after the enhanced processing are also inconsistent.

[0119] Exemplarily, the electronic device can switch the current color display mode to the DCI-P3 color display mode or the SRGB color display mode according to different usage scenarios. For example, when the electronic device is running different applications, it may automatically switch to different color display modes. For example, when running the first application, the electronic device can switch to the DCI-P3 color display mode, and when running the second application, the electronic device can switch to the SRGB color display mode. If the user calls up image 1 or image 2 for display when running the first application or the second application, then for the same image 1, the color display effect of image 1 or image 2 seen by the user in the first application is different from the color display effect of image 1 or image 2 seen in the second application, resulting in inconsistent display effects of the electronic device in different usage scenarios for the same content to be displayed, which can easily cause user confusion about the display effect and affect the user's usage experience.

[0120] Therefore, in the embodiment of the present application, when it is recognized that the color display mode of the electronic device is the DCI-P3 color display mode, and the first color of the content to be displayed is distributed in the first color gamut space, the first color corresponding to the second color display mode is first converted into the second color corresponding to the first color display mode according to the first color conversion matrix, and then the first color is enhanced according to the first color enhancement matrix. Exemplarily, after obtaining the first color conversion matrix and the first color enhancement matrix, the first color can be converted according to the first color conversion matrix to obtain the converted second color, and then the second color can be enhanced according to the first color enhancement matrix to obtain the enhanced second color, and the display screen is displayed according to the enhanced second color. In another example, the first color enhancement matrix can also be multiplied by the first color conversion matrix to obtain the target color enhancement matrix, and then the first color can be enhanced according to the target color enhancement matrix.

[0121] Among them, the first color of the content to be displayed is converted into the second color by the first color conversion matrix, so that when the color display mode of the electronic device is the second color display mode, the display effect of the second color is displayed, which is consistent or close to the display effect of the first color when the color display mode of the electronic device is the first color display mode. The second color is mapped from the first color gamut space to the third color gamut space by the first color enhancement matrix, so that when the display screen of the electronic device displays the content to be displayed, the displayed color is more vivid and has a higher saturation, thereby improving the display effect of the electronic device. Moreover, regardless of whether the color display mode of the electronic device is the first color display mode or the second color display mode, when displaying the content to be displayed whose color is located in the first color gamut space or the first color in the content to be displayed located in the first color gamut space, the display screen of the electronic device can maintain a consistent or close color display effect, thereby improving the user experience. Therefore, when the user uses the electronic device, the color of the first color gamut space in the content to be displayed will not have different display effects due to the switching of different color display modes, thereby improving the user experience.

[0122] The first color enhancement matrix acquisition method is referred to the above example and will not be described in detail here. The first color conversion matrix M (DCI-P3_2_sRGB) can be obtained as follows:

[0123] 2.1, the three vertex coordinates of the second color gamut space are combined into a matrix M (TargetColor), and M (Target) is calculated. Through M (Target), the RGB data can be converted to the XYZ space.

[0124] Specifically, the calculation process of M(Target) is as follows:

[0125]

[0126] First calculate xr , yr; xg , yg;xb,yb;xw , yw:

[0127] xr=R3x;

[0128] yr=R3y;

[0130] yg=G3y;

[0131] xb=B3x;

[0132] yb=B3y;

[0133] xw=W3x;

[0134] yw=W3y;

[0135] Wherein W3 is the coordinate of the white point of the second color gamut space.

[0136] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0137] Xr=xr / yr; Xg=xg / yg;

[0138] Yr=1; Yg=1;

[0139] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0140] Xb=xb / yb; Xw=xw / yw;

[0141] Yb=1; Yw=1;

[0142] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0143] Then calculate the temporary matrix M (XYZ_Matrix):

[0144]

[0145] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0146]

[0147] The matrix M(Target) is calculated:

[0148]

[0149] 2.2, the three vertex coordinates of the first color gamut space are combined into a matrix M (PanelColor), and M (Panel) is calculated. Through M (Panel), the RGB data can be converted to the XYZ space.

[0150]

[0151] First calculate xr, yr; xg, yg; xb, yb; xw, yw:

[0152] xr=R4x;

[0153] yr=R4y;

[0154] xg = G4x;

[0155] yg=G4y;

[0156] xb=B4x;

[0157] yb=B4y;

[0158] xw=W4x;

[0159] yw=W4y;

[0160] Where W4 is the coordinate of the white point in the maximum color gamut space of the display.

[0161] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0162] Xr=xr / yr; Xg=xg / yg;

[0163] Yr=1; Yg=1;

[0164] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0165] Xb=xb / yb; Xw=xw / yw;

[0166] Yb=1; Yw=1;

[0167] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0168] Then calculate the temporary matrix M (XYZ_Matrix):

[0169]

[0170] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0171]

[0172] The matrix M(Panel) is calculated:

[0173]

[0174] Calculate the inverse matrix M(InversePanel) of M(Panel);

[0175] The first color conversion matrix M(DCI-P3_2_sRGB)=M(InversePanel)*M(Target).

[0176] Exemplarily, the first color can be converted according to the first color conversion matrix to obtain a converted second color, and then the second color can be enhanced according to the first color enhancement matrix to obtain an enhanced second color, and the display screen displays according to the enhanced second color.

[0177] In another example, the first color enhancement matrix can be multiplied by the first color conversion matrix to obtain a target color enhancement matrix, and then the first color is enhanced according to the target color enhancement matrix; in another example, specifically, the three primary color data of the color in the content to be displayed are normalized to obtain normalized three primary color data; the normalized three primary color data are linearized to obtain linearized data; the linearized data is enhanced according to the target color enhancement matrix to obtain enhanced data; the enhanced data is inverse linearized to obtain inverse linearized data; the inverse linearized data is inverse normalized to obtain a new first color after enhancement; and the electronic device displays according to the new first color.

[0178] For example, the bit depth of the display screen is 12 bits, the three-primary color data 1 of the color 1 to be displayed is: (4095, 0, 0), and the three-primary color data 2 of the color 2 is: (2096, 788, 3840). The three-primary color data 1 of color 1 and the three-primary color data 2 of color 2 are normalized, wherein the three-primary color data 1 (4095, 0, 0) of color 1 is normalized to (4095 / 4095, 0 / 4095, 0 / 4095) to obtain the normalized three-primary color data 1 (1, 0, 0); the three-primary color data 2 (2096, 788, 3840) of color 2 is normalized to (2096 / 4095, 788 / 4095, 3840 / 4095) to obtain the normalized three-primary color data

[0179] 2(0.51844,0.192430,0.937729).

[0180] The normalized data 1(1,0,0) is linearized (1 2.2 , 0 2.2 ,0 2.2 ), and obtain the linearized data 1(1,0,0), and linearize the normalized data 1(0.51844,0.192430,0.937729) (0.51844 2.2 , 0.192430 2.2 ,0.937729 2.2 ), and obtain the linearized data

[0181] 2(0.229141, 0.226632, 0.868101), multiply the linearized data by the target color enhancement matrix, for example, the target color enhancement matrix is:

[0182]

[0183] Then the enhanced three-primary color data 1 is obtained as follows:

[0184]

[0185] Then the enhanced three-primary color data 2 is obtained as follows:

[0186]

[0187] The enhanced three-primary color data 1 (0.782103, 0.040155, 0.013673) is inversely linearized (0.782103 1 / 2.2 ,0.040188 1 / 2.2 ,0.013673 1 / 2.2 ), and the inverse linearized three-primary color data 1 (0.894301, 0.232005, 0.142123) is obtained. The enhanced three-primary color data 2 (0.211388, 0.050514, 0.766954) is inversely linearized (0.211388 1 / 2.2 ,0.050514 1 / 2.2 ,0.766954 1 / 2.2 ), and get the inverse linearized three-primary color data 2

[0188] (0.493421, 0.257419, 0.886385); then the inverse linearized three-primary color data 1 is inversely normalized (0.894301*4095, 0.232005*4095, 0.142123*4095), and the enhanced three-primary color data 1 (3602, 950, 582) is obtained, and the inverse linearized three-primary color data 2 is inversely normalized (0.493421*4095, 0.257419*4095, 0.886385*4095), and the enhanced three-primary color data 2 (2021, 1054, 3630) is obtained. Therefore, the three-primary color data of color 1 in the first color gamut space is (4095, 0, 0), and the three-primary color data mapped to the third color gamut space is (3602, 950, 582); the three-primary color data of color 2 in the first color gamut space is (2096, 788, 3840), and the three-primary color data mapped to the third color gamut space is (2096, 788, 3840).

[0189] In 207, if the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed also includes a color in the fourth color gamut space, the fourth color gamut space is set to a plurality of continuous sub-color gamut spaces, and the color in the fourth color gamut space is divided into fifth colors in different sub-color gamut spaces;

[0190] In 208, a fifth color gamut space is set, the fifth color gamut space is larger than the second color gamut space, and a plurality of continuous sub-enhancement spaces are set correspondingly between the third color gamut space and the fifth color gamut space, and the sub-color gamut spaces correspond to the sub-enhancement spaces one by one;

[0191] In 209, a first color change value of converting the first color into the second color is obtained; according to the sub-color conversion matrix corresponding to each sub-color gamut space, the fifth color of the corresponding sub-color gamut space is converted into a sixth color, the third color change value of converting the fifth color into the sixth color is less than the first color change value, and the further the sub-color gamut space is from the first color gamut space, the greater the difference between the third color change value of the sub-color conversion matrix corresponding to the sub-color conversion matrix and the first color change value;

[0192] In 211, the sixth color in each sub-color gamut space is enhanced according to its corresponding sub-color enhancement matrix, and the sub-color enhancement matrix is ​​used to map each of the sub-color gamut spaces to a corresponding sub-enhancement space.

[0193] In one embodiment, the color display mode of the electronic device is a DCI-P3 color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, so the color gamut space where the color of the content to be displayed is located is the second color gamut space, wherein the second color gamut space covers the second color gamut space, therefore, the color of the content to be displayed includes a first color located in the first color gamut space and a third color located in the first color gamut space and the second color gamut space, that is, the content to be displayed includes the first color located in the first color gamut space and the third color located in the fourth color gamut space.

[0194] Among them, the first color in the first color gamut space is converted into the second color through the first color conversion matrix, and there is a first color change value between the second color and the first color, that is, the first color in the first color gamut space in the content to be displayed has been converted into the second color, and the second color is enhanced according to the first color enhancement matrix. In order to make the first color of the content to be displayed in the first color gamut space and the third color in the fourth color gamut space naturally coordinated as a whole, the corresponding third color in the fourth color gamut space in the content to be displayed also needs to be color converted and enhanced.

[0195] Exemplarily, if the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed also includes a third color located in the fourth color gamut space, a fifth color gamut space is set, and the fifth color gamut space is larger than the second color gamut space; a first color change value of converting the first color to the second color is obtained; the third color is converted into a fourth color according to a second color conversion matrix corresponding to the fourth color gamut space, and a second color change value of converting the third color to the fourth color is less than the first color change value; the fourth color is enhanced according to the second color enhancement matrix, and the second color enhancement matrix is ​​used to map the fourth color gamut space to the fifth color gamut space.

[0196] Please refer to Figure 3 , the color gamut space included in L4 can be the fifth color gamut space. Exemplarily, the fifth color gamut space can be less than or equal to the maximum color gamut space of the display screen. The third color located in the fourth color gamut space is converted into the fourth color by the second color conversion matrix, and the second color change value of the third color converted into the fourth color is less than the first color change value, so that in the content to be displayed, the fourth color converted from the third color located in the fourth color gamut space and the second color converted from the first color located in the first color gamut space can relatively reduce the color difference between the two, and then the fourth color is enhanced, so that the first color of the content to be displayed located in the first color gamut space and the third color located in the fourth color gamut space can be naturally coordinated as a whole after the enhancement processing, and the embodiment of the present application does not directly convert the third color of the fourth color gamut space according to the first color conversion matrix, but converts according to the second color conversion matrix to reduce the color change value of the third color of the fourth color gamut space, so as to keep the original color of the content to be displayed in the fourth color gamut space as much as possible.

[0197] Furthermore, the embodiment of the present application considers setting a plurality of continuous sub-color gamut spaces, such as 20 continuous sub-color gamut spaces, in order to enable a more uniform transition between the color enhancement processing of the content to be displayed in the fourth color gamut space and the enhanced first color, and dividing the colors in the fourth color gamut space into fifth colors in different sub-color gamut spaces. Specifically, the sub-color gamut space to which the color belongs can be determined based on the three primary color data of the color of the content to be displayed.

[0198] In the embodiment of the present application, a plurality of continuous sub-enhancement spaces are set correspondingly between the third color gamut space and the fifth color gamut space, and the sub-color gamut spaces correspond to the sub-enhancement spaces one by one; for example, the fourth color gamut space is divided into 20 continuous sub-color gamut spaces, and the corresponding third color gamut space and the fifth color gamut space can also be divided into 20 continuous sub-enhancement spaces, so that the sub-color gamut spaces correspond to the sub-enhancement spaces one by one. It should be noted that the embodiment of the present application does not limit the specific number, and other numbers of sub-color gamut spaces and sub-enhancement spaces can be set.

[0199] According to the sub-color conversion matrix corresponding to each sub-color gamut space, the fifth color of the corresponding sub-color gamut space is converted into the sixth color, the third color change value of the fifth color converted into the sixth color is less than the first color change value, and the farther the sub-color gamut space is from the first color gamut space, the greater the difference between the third color change value of the corresponding sub-color conversion matrix and the first color change value, that is, based on the first color change value, the closer to the boundary of the second color gamut space, the smaller the color change value of the fifth color of the content to be displayed is, so that from the boundary of the first color gamut space to the boundary of the second color gamut, based on the first color change value, the fifth color change value of the content to be displayed becomes smaller and smaller, so that the sixth color converted from the fifth color in different sub-color gamut spaces can gradually and evenly transition based on the second color converted from the first color, while taking into account keeping the initial color of the original content in different sub-color gamut spaces as much as possible.

[0200] For example, the fourth color gamut space is divided into 20 continuous sub-color gamut spaces custom_i, and the third color gamut space and the fifth color gamut space are correspondingly divided into 20 continuous sub-enhancement spaces Target_i, and the sub-color gamut space custom_i corresponds to the sub-enhancement space Target_i one by one.

[0201] The sub-color conversion matrix M(DCI-P3_2_custom_i) is obtained as follows:

[0202] 3.1, the three vertex coordinates of the second color gamut space are combined into a matrix M (TargetColor), and M (Target) is calculated. Through M (Target), the RGB data can be converted to the XYZ space.

If the color display mode of the electronic device is the second color display mode, and the color of the content to be displayed also includes a seventh color located at the boundary of the second color gamut space, the seventh color is enhanced according to a third color enhancement matrix, and the third color enhancement matrix is ​​used to map the boundary of the second color gamut space to the boundary of the fifth color gamut space.

[0311] In one embodiment, the color display mode of the electronic device is a DCI-P3 color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard. Therefore, the color gamut space where the color of the content to be displayed is located is a second color gamut space, wherein the second color gamut space covers the first color gamut space. Therefore, the color of the content to be displayed includes a first color located in the first color gamut space, a third color located in the fourth color gamut space, and a seventh color located at the boundary of the second color gamut space. The first color of the content to be displayed located in the first color gamut space is converted into a second color by a first color conversion matrix, and the color change value between the first color and the second color is a first color change value. Starting from the boundary of the first color gamut space to the boundary of the second color gamut, based on the first color change value, the color change value of the fifth color of the content to be displayed located in different sub-color gamut spaces in the fourth color gamut space becomes smaller and smaller until the seventh color at the boundary of the second color gamut space no longer needs to be changed. Therefore, a third color enhancement matrix mapping the boundary of the second color gamut space to the boundary of the fifth color gamut space can be obtained, and the seventh color is enhanced and displayed according to the third color enhancement matrix, so that the overall color transition of the content to be displayed is uniform.

[0312] Specifically, the third color enhancement matrix M (DCI-P3Enhance2Panel) is obtained as follows:

[0313] 5.1, the three vertex coordinates of the fifth color gamut space are formed into a matrix M (TargetColor), wherein the fifth color gamut space may be less than or equal to the maximum color gamut space of the display screen. Exemplarily, the three primary color vertex coordinates of the fifth color gamut space may refer to Table 1, and M (Target) may be calculated, and RGB data may be converted to XYZ space through M (Target).

[0314] Specifically, the calculation process of M(Target) is as follows:

[0315]

[0317] xr=R7x;

[0318] yr=R7y;

[0320] yg=G7y;

[0321] xb=B7x;

[0322] yb=B7y;

[0323] xw=W7x;

[0324] yw=W7y;

[0325] Where W7 is the coordinate of the white point in the fifth color gamut space.

[0326] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0327] Xr=xr / yr; Xg=xg / yg;

[0328] Yr=1; Yg=1;

[0329] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0330] Xb=xb / yb; Xw=xw / yw;

[0331] Yb=1; Yw=1;

[0332] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0333] Then calculate the temporary matrix M (XYZ_Matrix):

[0334]

[0335] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0336]

[0337] The matrix M(Target) is calculated:

[0338]

[0339] 5.2, a matrix M(PanelColor) is formed by the coordinates of the three vertices of the maximum color gamut space that the display can display, and M(Panel) is calculated. Through M(Panel), the RGB data in M(TargetColor) can be converted to XYZ space.

[0340]

[0341] First calculate xr , yr; xg , yg;xb,yb;xw , yw:

[0342] xr=R2x;

[0343] yr=R2y;

[0344] xg=G2x;

[0345] yg=G2y;

[0346] xb=B2x;

[0347] yb=B2y;

[0348] xw=W2x;

[0349] yw=W2y;

[0350] Where W2 is the coordinate of the white point in the maximum color gamut space of the display.

[0351] Then calculate Xr, Yr, Zr; Xg, Yg, Zg; Xb, Yb, Zb and Xw, Yw, Zw:

[0352] Xr=xr / yr; Xg=xg / yg;

[0353] Yr=1; Yg=1;

[0354] Zr=(1-xr-yr) / yr; Zg=(1-xg-yg) / yg;

[0355] Xb=xb / yb; Xw=xw / yw;

[0356] Yb=1; Yw=1;

[0357] Zb=(1-xb-yb) / yb; Zw=(1-xw-yw) / yw;

[0358] Then calculate the temporary matrix M (XYZ_Matrix):

[0359]

[0360] Then calculate the inverse matrix M(XYZ_Matrix_inverse) of M(XYZ_Matrix), and calculate the matrix M(S):

[0361]

[0362] The matrix M(Panel) is calculated:

[0363]

[0364] Calculate the inverse matrix M(InversePanel) of M(Panel);

[0365] The third color enhancement matrix M(DCI-P3Enhance2Panel)=M(InversePanel)*M(Target).

[0366] Therefore, in the embodiment of the present application, when the color display mode of the electronic device is the DCI-P3 color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, the color gamut space where the color of the content to be displayed is located is the second color gamut space, then the color of the content to be displayed is divided into a first color located in the first color gamut space, a third color located in the fourth color gamut space, and a seventh color located at the boundary of the second color gamut space, the first color in the first color gamut space is converted into the second color according to the first color conversion matrix, and the second color is enhanced according to the first color enhancement matrix, so as to map the second color in the first color gamut space to the third color gamut space. Color gamut space; the third color of the fourth color gamut space is divided into fifth colors located in different sub-color gamut spaces, the fifth color in each sub-color gamut space is converted into a sixth color according to its corresponding sub-color conversion matrix, and then the sixth color is enhanced according to the corresponding sub-color enhancement matrix, so that the third color of the fourth color gamut space is evenly mapped to the fifth color gamut space; and the seventh color at the boundary of the second color gamut space is mapped to the boundary of the fifth color gamut space according to the third color enhancement matrix, so as to gradually realize the enhanced display of the overall color of the content to be displayed, so that the overall color of the content to be displayed is coordinated, natural and more vivid, thereby improving the display effect of the electronic device.

[0367] In one embodiment, if the color display mode of the electronic device is the first color display mode, and the color gamut space where the color of the content to be displayed is located is the second color gamut space, then the color of the content to be displayed corresponding to the second color gamut space is converted into the color of the new content to be displayed corresponding to the first color gamut space according to the fourth color conversion matrix, and the color of the new content to be displayed is enhanced according to the first color enhancement matrix.

[0368] For example, if the color display mode of the electronic device is the sRGB color display mode, and the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, then the color gamut space where the color of the content to be displayed is located is the second color gamut space. Since the color display mode of the electronic device cannot support the display of colors beyond the first color gamut space, it is necessary to obtain a fourth color conversion matrix, and convert the color of the content to be displayed in the second color gamut space into the color of the new content to be displayed corresponding to the first color gamut space through the fourth color conversion matrix, and enhance the color of the new content to be displayed according to the first color enhancement matrix.

[0369] The method for obtaining the fourth color conversion matrix may refer to the method for obtaining the first color conversion matrix, which will not be described in detail herein.

[0370] In the embodiment of the present application, when the color display mode of the electronic device is different, the display effect of the same color is different. For example, the first color display mode is the sRGB color display mode, and the second color display mode is the DCI-P3 color display mode. When the first color of the first color gamut space is displayed, the color display effect is different, which is easy to affect the user experience. In addition, considering that the color gamut space that the display screen of the current electronic device can display has exceeded the color gamut space that the color display mode can support, such as exceeding the color gamut space that the sRGB color display mode or the DCI-P3 color display mode can support. If the display screen of the electronic device is only used to display, for example, colors in the first color gamut space, the color display of the display screen is relatively dull, the colors are not rich enough, and the colors are not bright enough, which affects the display effect.

[0371] Therefore, the embodiment of the present application combines the current color display mode of the electronic device and the color gamut space where the color of the current content to be displayed is located, and performs corresponding color conversion processing and color enhancement processing, so that the display screen of the electronic device, regardless of whether it is in the first color display mode or the second color display mode, when displaying the color of the first color gamut space, the color display effect is consistent and the colors are more vivid, thereby improving the display effect of the electronic device.

[0372] For example, the color display mode of the electronic device is the sRGB color display mode, and the color of the content to be displayed is encoded by the sRGB color gamut standard, that is, the color gamut space where the color of the content to be displayed is located is the first color gamut space. In the embodiment of the present application, a third color gamut space can be set, and the third color gamut space is smaller than the second color gamut space and larger than the first color gamut space. According to the first color enhancement matrix, the color of the content to be displayed can be mapped from the first color gamut space to the third color gamut space, so that the display screen of the electronic device can display the color of the third color gamut space when displaying the content to be displayed, which exceeds the color of the first color gamut space. For another example, the color display mode of the electronic device is the DCI-P3 color display mode, and the content to be displayed includes a first color located in the first color gamut space. In the embodiment of the present application, According to the first color conversion matrix, the first color of the content to be displayed is converted into the second color, so that when the color display mode of the electronic device is the second color display mode, the display effect of the second color is displayed, which is consistent or close to the visual display effect of the first color when the color display mode of the electronic device is the first color display mode, and according to the first color enhancement matrix, the second color is mapped from the first color gamut space to the third color gamut space, so that when the display screen of the electronic device displays the content to be displayed, the color of the third color gamut space can be displayed, which exceeds the color of the first color gamut space, so that for the first color of the content to be displayed in the first color gamut space, no matter whether the color display mode of the electronic device is the first color display mode or the second color display mode, the display effect is consistent or close, thereby improving the user experience;Furthermore, the present application takes into account that the color of the content to be displayed is encoded by the DCI-P3 color gamut standard, and the content to be displayed includes a first color located in a first color gamut space and a third color located in a fourth color gamut space. It can be understood that the first color located in the first color gamut space is converted into a second color by a first color conversion matrix, and there is a first color change value between the second color and the first color. In order to make the third color of the content to be displayed located in the fourth color gamut space more evenly transition with the enhanced second color after enhancement processing, a plurality of continuous sub-color gamut spaces are set in the fourth color gamut space, the third color located in the fourth color gamut space is divided into fifth colors located in different sub-color gamut spaces, and a plurality of continuous sub-enhancement spaces are set correspondingly between the third color gamut space and the fifth color gamut space, and the sub-color gamut space corresponds to the sub-enhancement space one by one, and according to the sub-color conversion matrix corresponding to each sub-color gamut space, the fifth color of the corresponding sub-color gamut space is converted into a sixth color, and from the boundary of the first color gamut space to the boundary of the second color gamut, based on the first color change value, the fifth color change value of the sub-color gamut space becomes smaller and smaller until the second The seventh color at the boundary of the color gamut does not need to be changed, so that the overall color of the content to be displayed is naturally coordinated, and the initial color of the content to be displayed in different sub-color gamut spaces can be maintained as much as possible, and the sixth color converted from the fifth color of each sub-color gamut space is enhanced according to the sub-color enhancement matrix, and the seventh color at the boundary of the second color gamut space is enhanced according to the third color enhancement matrix, so that the color of the entire content to be displayed can be evenly mapped to the fifth color gamut space, and the display effect of the electronic device is enhanced. That is, in the embodiment of the present application, whether the content to be displayed is encoded by the sRGB color gamut standard or the DCI-P3 color gamut standard, it can be displayed vividly and without abnormality after the enhancement processing, and whether the color display mode of the electronic device is the sRGB color display mode or the DCI-P3 color display mode, all colors of the content to be displayed encoded by the sRGB color gamut standard and the first color in the content to be displayed encoded by the DCI-P3 color gamut standard are consistent or close in visual display effect after enhancement processing, thereby improving the visual experience of the user. ;
