[0046] 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.

[0047] In some embodiments, in the HSL color space, yellow, cyan, red, and blue with a brightness value (Ligntness) of 50 are sampled respectively. In the human eye perception, yellow will give people a very bright or even a bit dazzling feeling, while blue will give people a feeling of lower brightness. These colors are grayscaled, and the grayscale image can intuitively reflect that the perceived brightness of these colors decreases in the order of yellow, cyan, red, and blue. Therefore, the brightness value in the HSL color space is inconsistent with the perceived brightness value of the human eye.

[0048] In an exemplary embodiment of the present disclosure, in order to overcome the problems existing in the related art, a display method is provided, including: determining first color data of a first image in a first color space, the first color space represents a perceptual color space, the first color data includes a first parameter, and the first parameter represents the brightness of the color; based on the first parameter, color correction is performed on the first image to obtain a second image, and the hue of the first image and the second image is the same; and the second image is displayed. The display method performs color correction on the first image through the first parameter in the first color data, which can increase the readability of the display screen while maintaining the consistency of color cognition, and solves the problem of inconsistency between the color brightness value and the brightness value perceived by the human eye, and can improve the user experience of the display screen.

[0049] In an exemplary embodiment of the present disclosure, a display method is provided. Figure 1 is a flow chart of a display method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0050] Step S101, determining first color data of a first image in a first color space, where the first color space represents a perceptual color space, and the first color data includes a first parameter, where the first parameter represents the brightness of the color;

[0051] Step S102, based on the first parameter, color correction is performed on the first image to obtain a second image, and the hue of the first image and the second image is the same;

[0052] Step S103: display the second image.

[0053] The display method in the disclosed embodiment is applied to electronic devices, including electronic devices with display screens such as smart phones, tablets, personal computers, smart home devices, smart wearable devices, and smart car devices, or can also be directly applied to the display screen. The display method in the disclosed embodiment can be applied in any lighting environment, and can also be applied in special lighting environments such as strong lighting environments or weak lighting environments. When applied in special lighting environments, the electronic device detects the ambient light value, and when the ambient light value meets the special lighting environment conditions, the display method in the present embodiment is turned on. The display method in the present embodiment can be used as a default display method or as an optional display method. For example, in the display-related system settings, when the user chooses to turn on the display optimization function, the display method in the present embodiment is turned on.

[0054] In step S101, the first image represents the image to be displayed in the display screen, and the first color space represents the perceived color space, that is, the color space that conforms to the human eye's perception of color, and each color component therein is a human eye perception value. The first color space includes a first parameter, which is a color component in the first color space. The first parameter represents the brightness of the color, that is, the color perception brightness that conforms to the human eye's perception of color brightness. For example, the first color space is an HCT (Hue, Chroma, Tone) color space, including color components: hue Hue, saturation Chroma, brightness Tone, wherein hue is the perceived hue, saturation is the perceived saturation, and brightness is the perceived brightness, then the first parameter is brightness Tone. The first color data represents the values ​​of each color component of each pixel in the first image in the first color space, for example, the H value, C value, and T value of each pixel in the HCT color space are recorded as the first color data.

[0055] In step S102, the first parameter represents the color brightness perceived by the human eye, and the first image is color corrected according to the brightness perceived by the human eye to obtain a corrected first image, which is the second image. The correction method for color correction of the first image based on the first parameter is determined according to the lighting environment. For example, in a strong lighting environment, in order to see the content of the first image clearly, the first parameter of the first image needs to be increased, and in a weak lighting environment, in order to avoid glare, the first parameter of the first image needs to be reduced. In an ordinary lighting environment, the overexposure phenomenon can be eliminated by adjusting the first parameter.

[0056] Hue indicates the appearance of color. The characteristics of hue are determined by the spectral composition of the light source and the perception of the human eye caused by the ratio of radiation of various wavelengths reflected by the surface of the colored object. Hue is used to distinguish different colors. For example, different colors such as pink, scarlet, yellow, and blue are distinguished by hue. Therefore, in order to ensure that the color perception of the image is the same before and after color correction, the hue value is not adjusted during the color correction process, that is, the hue of the first image and the second image is the same. For example, if a pixel in the first image is pink, then the pixel in the second image is still pink.

[0057] In step S103, the second image is displayed on the display screen, which can increase the readability of the content on the display screen.

[0058] In an exemplary embodiment of the present disclosure, by acquiring first color data of a first image in a first color space, the perceived color data of the first image is obtained, and color correction is performed on the first image through a first parameter in the first color data to obtain a second image. The display effect of the first image can be adjusted to adapt to the current ambient lighting, thereby increasing the readability of the display screen. In addition, the hue of the first image and the second image is the same, thereby ensuring that the color perception of the first image and the color perception of the second image remain consistent, and solving the problem of inconsistency between the color brightness value and the brightness value perceived by the human eye, thereby bringing users a better sunlight screen usage experience and improving users' usage experience of the display screen.

[0059] In an exemplary embodiment of the present disclosure, a display method is provided. Figure 2 is a flow chart of a display method according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0060] Step S201, determining first color data of a first image in a first color space, where the first color space represents a perceptual color space, and the first color data includes a first parameter, where the first parameter represents the brightness of the color;

[0061] Step S202, obtaining an initial value of a first parameter and distribution data of the first parameter in a first image;

[0062] Step S203, determining a correction value of the first parameter based on the distribution data of the first parameter, and the initial value of the first parameter and a first mapping relationship, wherein the first mapping relationship represents a mapping relationship between the initial value of the first parameter and the correction value of the first parameter;

[0063] Step S204, performing color correction on the first image based on the correction value of the first parameter to obtain a second image;

[0064] Step S205: display the second image.

[0065] The specific implementation of step S201 and step S205 refers to step S101 and step S103, which will not be repeated here.

[0066] In step S202, the value of the first parameter of each pixel in the first image is obtained, and the initial value of the first parameter represents the value of the first parameter before the color correction is performed on the first image. The distribution data of the first parameter represents the distribution of the value of the first parameter in the first image, and the distribution data of the first parameter can be represented by a histogram, in which the horizontal axis is the initial value of the first parameter and the vertical axis is the number of pixels corresponding to the initial value of the first parameter. For example, in the first image, the T value of each pixel in the HCT color space is obtained, the T values ​​of all pixels are counted, and the distribution of the T value is represented by a histogram. In the T value histogram, the horizontal axis is the T value and the vertical axis is the number of pixels corresponding to the T value.

[0067] In step S203, the distribution data of the first parameter can reflect the distribution of color brightness of the first image. In order to ensure the color consistency between the first image and the second image before and after color correction, the distribution of the corrected first parameter in the second image needs to be consistent with the distribution of the first parameter in the first image.

[0068] The first mapping relationship represents the mapping relationship between the initial value of the first parameter and the correction value of the first parameter. The first mapping relationship can be a mapping relationship table or a functional relationship. The first mapping relationship is obtained from experimental data. For example, in a strong light environment, the initial value of the first parameter is 40, and the displayed content cannot be seen. When it is adjusted to above 90, that is, when the correction value of the first parameter is greater than 90, the displayed content can be seen. When the initial value of the first parameter is 40, the corresponding correction value of the first parameter is above 90. Thus, a set of mapping relationships is obtained. The correction values ​​corresponding to different initial values ​​of the first parameter are obtained in turn, and the first mapping relationship can be obtained. It should be noted that the first mapping relationships of different display screens may be different, and the first mapping relationship corresponding to the display screen needs to be determined according to the characteristics of the display screen.

[0069] The initial value of the first parameter of each pixel in the first image is obtained, and the correction value of the first parameter of each pixel is matched through the first mapping relationship, and then the correction value of the first parameter of each pixel is adjusted according to the distribution of the initial value of the first parameter in the first image, so that the distribution of the correction value of the first parameter is the same as the distribution of the initial value of the first parameter. For example, in the first image, the initial values ​​of the first parameters of pixel 1, pixel 2, and pixel 3 are 30, 40, and 50 respectively. In a strong light environment, they all need to be adjusted to above 90, that is, the correction values ​​of the first parameters of the three pixels are all greater than 90. At this time, the correction value of the first parameter of each pixel is determined according to the distribution of the initial values ​​of the first parameters of the three pixels. That is, since the initial value of the first parameter increases successively, the correction value of the first parameter also needs to increase successively, and the correction values ​​of the first parameter are 90, 100, and 110 respectively.

[0070] In step S204, the initial value of the first parameter of each pixel in the first image is replaced by the corrected value of the first parameter corresponding to each pixel, thereby completing the color correction of the first image and obtaining the second image.

[0071] In this embodiment, while enhancing the readability of the display screen, it is possible to ensure that the distribution of the first parameter in the first image and the second image is the same before and after color correction, so as to ensure color consistency between the first image and the second image.

[0072] In an exemplary embodiment of the present disclosure, a display method is provided. Figure 3 is a flow chart of a display method according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0073] Step S301, obtaining second color data of a first image in a second color space, where the second color space represents a color space related to a display device;

[0074] Step S302, converting the second color data into first color data in a first color space, the first color space represents a perceptual color space, the first color data includes a first parameter, and the first parameter represents the brightness of the color;

[0075] Step S303, obtaining an initial value of a first parameter and distribution data of the first parameter in the first image;

[0076] Step S304, determining a correction value of the first parameter based on the distribution data of the first parameter, and the initial value of the first parameter and a first mapping relationship, wherein the first mapping relationship represents a mapping relationship between the initial value of the first parameter and the correction value of the first parameter;

[0077] Step S305, obtaining an initial value of the second parameter in the first image;

[0078] Step S306, determining a corrected value of the second parameter based on the initial value of the first parameter, the initial value of the second parameter, the corrected value of the first parameter, and the first relationship; wherein the first relationship represents a relationship between the first value and the second value, the first value is a difference between the corrected value of the first parameter and the initial value of the first parameter, and the second value is a difference between the corrected value of the second parameter and the initial value of the second parameter;

[0079] Step S307, based on the correction value of the first parameter and the correction value of the second parameter, color correction is performed on the first parameter and the second parameter of the first image to obtain first corrected color data of the second image in the first color space;

[0080] Step S308, converting the first corrected color data of the second image in the first color space into second corrected color data in the second color space;

[0081] Step S309: displaying a second image based on the second corrected color data.

[0082] The specific implementation of step S303-step S304 refers to step S202-step S203, which will not be repeated here.

[0083] In step S301, the second color space represents a color space related to the display device, that is, in the second color space, different display devices may display different colors, for example, the second color space is an RGB color space. The second color data represents the value of each color component of each pixel in the first image in the second color space, for example, the R value, G value, and B value of each pixel in the RGB color space are recorded as the second color data.

[0084] In step S302, the second color data is converted into the first color data in the first color space, that is, the second color space is converted into the first color space. The existing color space conversion method can be used, for example, color space conversion is performed based on a color space conversion matrix. When the second color space is an RGB color space and the first color space is an HCT color space, the RGB color space is converted into the HCT color space by the following formula:

[0085]

[0086] Wherein, X represents the conversion matrix between the second color space and the first color space.

[0087] In some possible implementations, the second color data is converted into third color data in a third color space, where the third color space represents a color space that is independent of a display device; and the third color data is converted into the first color data.

[0088] The third color space represents a color space that is independent of the display device, that is, under the third color space, there will be no difference in the colors displayed by different display devices, for example, the third color space is an XYZ color space. The second color data is converted into the third color data, and then the third color data is converted into the first color data, that is, the second color space is converted into the third color space, and then the third color space is converted into the first color space, and the existing color space conversion method can be used. For example, based on the color space conversion matrix, when the second color space is the RGB color space, the third color space is the XYZ color space, and the first color space is the HCT color space, the RGB color space is converted into the XYZ color space by the following formula:

[0089]

[0090] Among them, X 1 Represents the conversion matrix between the second color space and the third color space.

[0091] The XYZ color space is then converted to the HCT color space using the following formula:

[0092]

[0093] Among them, X 2 Represents a conversion matrix between the third color space and the first color space.

[0094] Since the third color data is device-independent color data, the second color data is first converted into the third color data, and then the third color data is converted into the first color data, so that the accuracy of the first color data can be ensured.

[0095] In step S305, the first color data also includes a second parameter, which is another color component in the first color space. The second parameter represents the saturation of the color, that is, the color perception saturation that conforms to the law of color saturation perception of the human eye. For example, if the first color space is the HCT color space, the second parameter is the saturation Chroma. The initial value of the second parameter represents the value of the second parameter of each pixel in the first image before the second parameter is adjusted.

[0096] In step S306, taking the first color space as the HCT color space as an example, the initial value of the first parameter is recorded as T input , the correction value of the first parameter is recorded as T output , the initial value of the second parameter is recorded as C input , the correction value of the second parameter is recorded as C output , then the first value ΔT is expressed as: ΔT = T output -T input , the second value ΔC is expressed as: ΔC = C output -C input The first relationship represents the relationship between the first value ΔT and the second value ΔC. Therefore, after obtaining the initial value of the first parameter, the correction value of the first parameter, and the initial value of the second parameter, substituting them into the first relationship can obtain the correction value of the second parameter.

[0097] In one example, the first relationship is expressed as:

[0098] ΔE=(ΔT 2 +ΔC 2 / (K_s×C-1)) 0.5

[0099] Wherein, ΔE represents the perceived color difference between the second image and the first image, which is the set value, ΔT represents the first value, ΔC represents the second value, K_s represents a constant, which is usually 1, and C_1 represents the initial value C of the second parameter. input The correction value C of the second parameter output If the first image and the second image satisfy the first relationship, that is, the images before and after color correction satisfy the first relationship, it means that the color saturation difference and the color perceived brightness difference of the images before and after color correction are within the preset range, that is, the color perception of the images before and after color correction is consistent.

[0100] In step S307, the initial value of the first parameter of each pixel in the first image is replaced by the corrected value of the first parameter corresponding to each pixel, and the initial value of the second parameter of each pixel in the first image is replaced by the corrected value of the second parameter corresponding to each pixel, thereby completing the color correction of the first image and obtaining the first corrected color data of the second image in the first color space. The first corrected color data includes the corrected value of the first parameter, the corrected value of the second parameter and the hue, and when the first color space is the HCT color space, the first corrected color data includes the corrected C value and the corrected T value, and the uncorrected H value.

[0101] Since the color gamut range of the display screen has limited coverage of the color space, the color gamut range of some displays cannot cover all colors. When the color brightness increases, the display screen may be distorted, causing some colors to be displayed as darker colors, making the colors displayed on the display screen look dimmer and unsaturated. Therefore, when performing color correction on the first image, adjusting the perceived brightness and perceived saturation of the color at the same time can avoid unrealistic color display caused by a decrease in color saturation when the color brightness is too high, further optimize the display effect, and enhance the user experience of the display screen.

[0102] In step S308, the first corrected color data of the second image in the first color space is converted into the second corrected color data in the second color space, that is, the first color space is converted into the second color space, and the inverse conversion method of converting the second color space into the first color space is adopted. For example, when the second color space is the RGB color space and the first color space is the HCT color space, the RGB color space is converted into the HCT color space by the following formula:

[0103]

[0104] Among them, X -1 Represents the inverse matrix of the conversion matrix between the second color space and the first color space.

[0105] In some possible implementations, the first corrected color data is converted into third corrected color data in a third color space; and the third corrected color data is converted into second corrected color data.

[0106] The inverse conversion method is also used. For example, when the second color space is an RGB color space, the third color space is an XYZ color space, and the first color space is an HCT color space, the HCT color space is converted into the XYZ color space by the following formula:

[0107]

[0108] Among them, X 2 -1 Represents the inverse matrix of the conversion matrix between the third color space and the first color space.

[0109] Then convert the XYZ color space to RGB color space using the following formula:

[0110]

[0111] Among them, X 1 -1 Represents the inverse matrix of the conversion matrix between the second color space and the third color space.

[0112] The method of converting the first corrected color data of the second image in the first color space into the second corrected color data in the second color space and the method of converting the second color data of the first image in the second color space into the first color data in the first color space are inverse methods.

[0113] In step S309, the second image is displayed based on the second corrected color data, that is, the image after color correction is displayed.
