[0066] 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.

[0067] The technical solutions provided by various embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0068] In the related art, in different application scenarios, users have different demands for the eye protection mode of mobile phones, but the eye protection mode in current mobile phones is fixed and cannot achieve different eye protection effects according to the different colors displayed on the mobile phone screen.

[0069] Based on this, an embodiment of the present disclosure provides a display adjustment method. Figure 1 is a flow chart of a display adjustment method according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the display adjustment method provided by the embodiment of the present disclosure includes at least the following steps:

[0070] Step 110: obtaining initial color information displayed on the screen of the electronic device;

[0071] Step 120: When it is determined based on the initial color information that the blue light information displayed on the screen meets a preset condition, the initial color information is adjusted based on the blue light information displayed on the screen to obtain target color information;

[0072] Step 130: Perform screen display based on the target color information.

[0073] In step 110, the electronic devices may include: mobile phones, tablet computers, smart watches, digital cameras, head mounted display devices (Head Mounted Display, HMD), etc., which are not limited in the embodiments of the present disclosure.

[0074] In the embodiments of the present disclosure, the display adjustment method may be executed by the electronic device at any time, or may be executed by the electronic device when the electronic device is in the eye protection mode, etc., and the embodiments of the present disclosure are not limited thereto.

[0075] Here, the eye protection mode of the electronic device may be that the electronic device reduces the proportion of blue light by adjusting the color temperature of the screen to reduce damage to the eyes.

[0076] Among them, color temperature is a unit of measurement that indicates the color components contained in light. Theoretically, color temperature refers to the color of an absolute black body after being heated from absolute zero (-273℃). After being heated, a black body gradually changes from black to red, yellow, white, and finally emits blue light. When heated to a certain temperature, the spectral components of the light emitted by the black body are called the color temperature at this temperature, and the unit is Kelvin (K). Blue light refers to high-energy visible light with a wavelength between 400 nanometers (nm) and 500nm emitted by the screen. Blue light can penetrate the lens and reach the retina directly, causing atrophy or even death of retinal pigment epithelial cells.

[0077] The initial color information may include the color system (Red Green Blue, RGB) value of any pixel displayed on the screen of the electronic device, or the brightness, hue or saturation of any pixel displayed on the screen of the electronic device, which is not limited in the embodiments of the present disclosure. For example, the initial color information may be the RGB value corresponding to the green pixel displayed on the screen.

[0078] It can be understood that obtaining the initial color information of the screen display in the above-mentioned electronic device may include: obtaining the initial color information of all pixels in the screen display picture of the above-mentioned electronic device; or obtaining the initial color information of some pixels in the screen display picture of the above-mentioned electronic device.

[0079] In an embodiment of the present disclosure, after the electronic device turns on a functional mode such as an eye protection mode, the electronic device can obtain the initial color information of each pixel in the screen display image, so as to subsequently judge the initial color information of each pixel to determine whether the initial color information needs to be adjusted.

[0080] In step 120, the blue light information may be blue light information corresponding to any pixel displayed on the screen of the electronic device; for example, the blue light information may include blue light proportion, blue light brightness, blue light saturation or blue light hue, etc. The target color information may be eye protection color information displayed on the screen after adjusting the initial color information.

[0081] Among them, the blue light proportion can be the ratio of the blue spectrum intensity to the spectrum intensity of the full spectrum; the full spectrum can refer to the spectrum including ultraviolet light, visible light, and infrared light; the spectrum wavelength of the full spectrum can cover all visible light regions (wavelength is 380nm-780nm).

[0082] Here, the above-mentioned blue light information satisfies the preset condition, which can be understood as the above-mentioned blue light information can indicate that the above-mentioned initial color information belongs to an eye-damaging color, that is, the initial color information displayed on the screen needs to be adjusted. For example, in the case where the above-mentioned blue light information is a blue light ratio, the above-mentioned blue light information satisfies the preset condition may include: the above-mentioned blue light ratio is less than or equal to the first blue light threshold, or the above-mentioned blue light ratio is greater than or equal to the second blue light threshold.

[0083] Similarly, determining that the blue light information meets the preset condition based on the initial color information may include: obtaining the blue light information based on the initial color information, and then determining that the blue light information meets the preset condition.

[0084] In one embodiment of the present disclosure, the blue light information includes a blue light ratio; and the display adjustment method may further include:

[0085] The color value in the initial color information is input into a preset blue light model to obtain the blue light proportion.

[0086] In this way, the color value in the initial color information can be input into the preset blue light model to obtain the blue light proportion, so as to prepare for the subsequent judgment of whether the initial color information needs to be adjusted and to adjust the initial color information, thereby achieving the eye protection effect of the electronic device.

[0087] Among them, the color values ​​in the above-mentioned initial color information can be R values, G values ​​and B values; the above-mentioned preset blue light model can include a machine learning model about RGB values ​​and blue light proportions, or a functional relationship between RGB values ​​and blue light proportions, etc.

[0088] In one embodiment of the present disclosure, the display adjustment method may further include:

[0089] Get multiple sample color values ​​of multiple sample display images;

[0090] Obtaining a plurality of sample blue light proportions of a plurality of the sample display images;

[0091] Based on the sample color values ​​and the sample blue light proportion associated with the same sample display screen, a preset training model is trained to obtain the blue light model.

[0092] In this way, the preset training model can be trained through multiple sample color values ​​and multiple sample blue light proportions of multiple sample display images to obtain a blue light model, so that the color value of the initial color information can be directly input into the blue light model in the future to obtain the corresponding blue light proportion, thereby improving the adjustment efficiency of the initial color information and better realizing the eye protection effect of the electronic device.

[0093] Among them, the above-mentioned sample display screen can be an image displayed on the screen of the above-mentioned electronic device based on the sample color value; the above-mentioned sample color value can be one of the standard RGB values; the above-mentioned sample blue light ratio can be the ratio of the sample blue spectrum intensity in the above-mentioned sample display screen to the sample spectrum intensity; the above-mentioned preset training model can be an initial machine learning model that has not yet been trained.

[0094] It can be understood that in the process of training the above-mentioned training model, a plurality of the above-mentioned sample display screens are displayed on the screen of the electronic device to obtain a plurality of the above-mentioned sample color values, and the corresponding plurality of the above-mentioned sample blue light proportions are determined based on the measurement results of the light measuring device, so that the sample color values ​​of the same sample display screen are associated with the sample blue light proportions, so as to train the preset training model to obtain the above-mentioned blue light model.

[0095] In one embodiment of the present disclosure, the step of obtaining a plurality of sample blue light proportions of a plurality of sample display images includes:

[0096] Measuring the plurality of sample display images by a light measuring device to determine the spectral intensities of the plurality of samples;

[0097] Based on the sample blue spectrum intensities among the multiple sample spectrum intensities, the multiple sample blue light proportions are obtained.

[0098] In this way, a plurality of sample display images can be measured by a light measuring device to determine a plurality of sample spectral intensities, and a plurality of sample blue spectral intensities can be determined from the plurality of sample spectral intensities, and then a plurality of sample blue light proportions can be calculated, so that they can be associated with a plurality of sample color values ​​to train the training model to obtain a blue light model, thereby improving the efficiency of adjusting the initial color information in the subsequent process and better realizing the eye protection effect of the electronic device.

[0099] The above-mentioned light measuring device may include a spectrometer. A spectrometer, also known as a spectrometer, is a device that uses a photomultiplier tube or other light detector to measure the intensity of a spectrum line at different wavelengths. The spectrometer is composed of an input slit, a dispersion system, an imaging system, and one or more output slits. The dispersion element is used to separate the electromagnetic radiation of the radiation source into the required wavelength or wavelength region, and the intensity is measured at the selected wavelength.

[0100] The sample spectrum intensity may be the spectrum intensity corresponding to all wavelengths separated from the sample color value by the light measuring device; the sample blue spectrum intensity may be the spectrum intensity corresponding to the blue light wavelength separated from the sample color value by the light measuring device.

[0101] Here, after measuring the sample spectral intensity by a light measuring device, the sample blue spectral intensity can be determined from the sample spectral intensity, and then the ratio of the sample blue spectral intensity to the sample spectral intensity can be calculated to obtain the above-mentioned sample blue light ratio, thereby associating the sample color value and the sample blue light ratio of the same sample display screen to train the training model to obtain a blue light model.

[0102] Exemplarily, a light measuring device such as a spectrometer CS20000 can be used to measure multiple sample color values ​​in a 3D look up table (LUT) of a mobile phone color calibration module, such as the sample spectral intensity of all 4913 standard RGB values ​​at 380nm-780nm, and then the proportion of the sample blue spectrum 400nm-500nm intensity to the sample spectral intensity is calculated to obtain the sample blue light proportion.

[0103] In some examples, the above blue light model may be formula (1).

[0104] P blue =M(R,G,B)=m r ·R+m g ·G+m b ·B+m c (1)

[0105] Among them, m r 、m g 、m b and m ccan be preset parameter values; blue It can be the above-mentioned blue light ratio; R, G, and B can be the color values ​​in the above-mentioned initial color information.

[0106] It can be understood that for the above-mentioned preset blue light model, by inputting the color value in the initial color information of any pixel point, the blue light proportion corresponding to the color value can be output.

[0107] In the embodiment of the present disclosure, the adjustment object of the above-mentioned electronic device may be the initial color information of the pixel point when the blue light information of the pixel point displayed on the screen meets the preset conditions; that is, when the blue light information of the pixel point displayed on the screen meets the preset conditions, the electronic device may adjust the initial color information of the pixel point based on the blue light information to obtain the eye protection color information displayed on the pixel point, that is, the target color information.

[0108] It should be noted that adjusting the above-mentioned initial color information to obtain the target color information may include at least one of the following: adjusting the hue of the above-mentioned initial color information to obtain the target color information; adjusting the saturation of the above-mentioned initial color information to obtain the target color information; adjusting the brightness of the above-mentioned initial color information to obtain the target color information; performing matrix change adjustment on the above-mentioned initial color information to obtain the target color information; adjusting the RGB value of the above-mentioned initial color information to obtain the target color information.

[0109] Here, based on the blue light information, the initial color information is adjusted to obtain the target color information, which may include: determining an adjustment coefficient based on the blue light proportion, and then adjusting the initial color information based on the adjustment coefficient to obtain the target color information; or, determining an adjustment coefficient based on the blue light brightness, and then adjusting the initial color information based on the adjustment coefficient to obtain the target color information; or, determining an adjustment coefficient based on the blue light saturation, and then adjusting the initial color information based on the adjustment coefficient to obtain the target color information; and so on.

[0110] In one embodiment of the present disclosure, the display adjustment method may further include:

[0111] When the blue light information does not satisfy the preset condition, the initial color information is used as the target color information.

[0112] In this way, when the blue light information does not meet the preset conditions, the initial color information displayed on the screen is not adjusted, so that only the initial color information that needs to be adjusted on the screen is adjusted, thereby improving the efficiency of the electronic device in adjusting the screen display.

[0113] In the embodiment of the present disclosure, when the blue light information is a blue light ratio, the blue light information not satisfying the preset condition may include: the blue light ratio is greater than a first blue light threshold, and the blue light ratio is less than a second blue light threshold.

[0114] It can be understood that the blue light information corresponding to all the pixels displayed on the above-mentioned screen may meet the preset conditions, that is, the initial color information of all the pixels needs to be adjusted; or, the blue light information corresponding to all the pixels displayed on the above-mentioned screen may not meet the preset conditions, that is, the initial color information of all the pixels does not need to be adjusted; or, the blue light information corresponding to some of the pixels displayed on the above-mentioned screen may meet the preset conditions, and the blue light information corresponding to another part of the pixels does not meet the preset conditions, that is, the initial color information of some pixels needs to be adjusted, and the initial color information of another part of the pixels does not need to be adjusted; and so on.

[0115] For example, a picture with various colors is displayed on the screen of the electronic device. According to the color classification in the picture, the picture may include pixels of the first part and pixels of the second part. If the proportion of blue light corresponding to the pixels of the first part meets the above preset conditions, the initial color information of the pixels of the first part needs to be adjusted to achieve the eye protection effect; if the proportion of blue light corresponding to the pixels of the second part does not meet the above preset conditions, the initial color information of the pixels of the second part does not need to be adjusted, that is, the eye protection effect has been achieved.

[0116] In step 130, after obtaining the target color information based on the initial color information and the blue light information displayed on the screen, the electronic device may display the target color information on the screen, thereby achieving an eye protection effect of the electronic device.

[0117] A display adjustment method provided by an embodiment of the present disclosure may include: obtaining initial color information displayed on a screen of an electronic device; in the case where it is determined based on the initial color information that the blue light information displayed on the screen meets a preset condition, adjusting the initial color information based on the blue light information displayed on the screen to obtain target color information; and performing screen display based on the target color information. That is, unlike the related art in which the eye protection mode of an electronic device is fixed, the embodiment of the present disclosure can adjust the initial color information displayed on the screen through the blue light information displayed on the screen of the electronic device to obtain target color information, so that different eye protection effects can be achieved when the screen displays different colors, thereby achieving better eye protection effects while ensuring that the display effects of different colors make the screen display colors more harmonious, thereby improving the user experience and comfort.

[0118] In one embodiment of the present disclosure, step 120 may be implemented in various ways.

[0119] A specific implementation example is given below, where the above blue light information includes the blue light ratio of the blue spectrum intensity to the spectrum intensity of the full spectrum. It should be noted that the following is only an example and is not intended to be limiting.

[0120] Figure 2 is a flow chart of a display adjustment method according to an exemplary embodiment. Figure 2 . See Figure 2 , step 120 in the display adjustment method provided in the embodiment of the present disclosure may include:

[0121] Step 121: When the blue light ratio meets the preset condition, determine an adjustment coefficient based on the blue light ratio;

[0122] Step 122: Adjust the initial color information based on the adjustment coefficient to obtain the target color information.

[0123] In step 121, the adjustment coefficients may be coefficients for adjusting the initial color information; for example, the adjustment coefficients may include R coefficients, G coefficients and B coefficients corresponding to the color values, and the R coefficients, G coefficients and B coefficients may also constitute an RGB matrix to adjust the initial color information.

[0124] In step 122, the blue light proportion may be within different blue light threshold ranges, so that the adjustment coefficients are different, and thus the initial color information may be adjusted based on different adjustment coefficients to obtain the target color information.

[0125] For example, the target color information R out G out B out The calculation formula can be Among them, R in G in B in can be the color value of the above initial color information, R p G p B p It can be the above adjustment factor.

[0126] In one embodiment of the present disclosure, step 121 may specifically include:

[0127] When the blue light proportion is less than or equal to a first blue light threshold, determining a first adjustment coefficient based on the blue light proportion;

[0128] When the blue light proportion is greater than or equal to a second blue light threshold, determining a second adjustment coefficient based on the blue light proportion;

[0129] The first adjustment coefficient is different from the second adjustment coefficient.

[0130] In this way, when the proportion of blue light is different, the first adjustment coefficient and the second adjustment coefficient can be determined based on the proportion of blue light in two different ways to achieve subsequent adjustment of the initial color information, thereby better realizing the eye protection effect of the electronic device and improving the user experience and comfort.

[0131] The first blue light threshold may be a critical threshold of the blue light ratio; for example, the first blue light threshold may be 50 or 60. The second blue light threshold may be another critical threshold of the blue light ratio; for example, the second blue light threshold may be 70 or 80. It should be noted that the first blue light threshold may be smaller than the second blue light threshold.

[0132] Here, the first adjustment coefficient may be a coefficient for adjusting the initial color information for eye protection when the proportion of blue light is less than or equal to the first blue light threshold; the second adjustment coefficient may be a coefficient for adjusting the initial color information for eye protection when the proportion of blue light is greater than or equal to the second blue light threshold.

[0133] It can be understood that when the above-mentioned blue light proportion is in different blue light ranges, different adjustment coefficients, namely the first adjustment coefficient or the second adjustment coefficient, can be obtained through different calculation methods, so that the screen display color can be more harmonious while better realizing the eye protection effect of the electronic device.

[0134] In the present disclosure, Figure 3 As shown, the horizontal axis is the blue light ratio, and the vertical axis is the number of colors corresponding to the blue light ratio. According to the above preset blue light model, the blue light ratio and the corresponding number of colors of the complete 4913 standard RGB values ​​are established; that is, there are 4913 RGB values, that is, the total number of colors is 4913. For example, Figure 3 As shown, the proportion of blue light is between 128-136.5, which corresponds to 150 colors.

[0135] For example, Figure 4 As shown in FIG. 1 , the horizontal axis is the proportion of blue light, and the vertical axis is the color temperature corresponding to the proportion of blue light. Taking the display color temperature of electronic devices such as mobile phones as 6500K of the International Commission on Illumination (Commission Internationale de l'Eclairage, CIE) 2015 daylight trajectory as an example, Figure 4It can be seen that the entire blue light ratio can be divided into a low blue light interval, a medium blue light interval and a high blue light interval, wherein the grayscale RGB value, i.e., the grayscale interval where R=G=B is located, corresponds to the medium blue light interval, i.e., the blue light ratio is 60-70, and the color temperature mapped to all colors in this interval is the standard color temperature CCT0, i.e., 6500K. Accordingly, the above blue light ratio meets the preset condition, i.e., the above blue light ratio is in the medium blue light interval; and the above blue light ratio does not meet the preset condition, i.e., the above blue light ratio is in the low blue light interval or the high blue light interval.

[0136] In order to ensure that the grayscale RGB value can accurately reach the display color temperature of the mobile phone, the colors in the high blue light range that are more harmful to the eyes are mapped to lower and warmer color temperatures to reduce damage to the eyes; the colors in the low blue light range are mapped to higher and colder color temperatures to reduce the subjective yellowish effect caused by the warm color temperature.

[0137] It should be noted that the above-mentioned determination of the first adjustment coefficient based on the blue light ratio can be implemented in various different ways. The following are only examples and are not intended to be limiting.

[0138] In some embodiments, determining the first adjustment coefficient based on the blue light proportion includes:

[0139] Based on the blue light proportion, determining a first offset color temperature;

[0140] The first adjustment coefficient is determined based on the first offset color temperature.

[0141] In this way, the first offset color temperature can be obtained by the proportion of blue light, and then the first adjustment coefficient can be determined by the first offset color temperature to achieve subsequent adjustment of the initial color information, thereby better realizing the eye protection effect of the electronic device and improving the user experience and comfort.

[0142] Among them, the above-mentioned first offset color temperature can be the eye protection color temperature corresponding to the pixel point displayed on the above-mentioned screen, which needs to be adjusted on the basis of the standard color temperature.

[0143] In one embodiment of the present disclosure, determining the first offset color temperature based on the blue light proportion includes:

[0144] Determining a first color temperature coefficient based on the blue light proportion, the first blue light threshold, a preset minimum blue light proportion, and a preset color temperature index;

[0145] The first offset color temperature is obtained based on the first color temperature coefficient and a preset color temperature difference value.

[0146] In this way, the first color temperature coefficient can be determined by the blue light proportion, the first blue light threshold, the preset minimum blue light proportion and the preset color temperature index, and then the first offset color temperature can be obtained by the first color temperature coefficient and the preset color temperature difference value, so as to determine the first adjustment coefficient in the subsequent process, and further realize the subsequent adjustment of the initial color information, so as to better realize the eye protection effect of the electronic device and enhance the user experience and comfort.

[0147] It can be understood that the process of obtaining the preset minimum blue light ratio may include: determining the blue light ratios of multiple samples corresponding to the multiple sample color information according to the multiple sample color information and the above blue light model; and selecting the minimum blue light ratio from the multiple sample blue light ratios. That is, multiple sample RGB values ​​are input into the above blue light model to obtain the blue light ratios of multiple samples corresponding to the multiple sample RGB values, and then the multiple sample blue light ratios are compared to obtain the above minimum blue light ratio.

[0148] The process of acquiring the preset color temperature index may include: determining the color temperature index based on the standard color temperature, the first color temperature threshold, the second color temperature threshold, and the first setting coefficient.

[0149] Here, the first color temperature threshold may be greater than the standard color temperature, and the standard color temperature may be greater than the second color temperature threshold; for example, the standard color temperature may be 6500 K, the first color temperature threshold may be 7000 K, and the second color temperature threshold may be 4000 K. The first setting coefficient may be a coefficient preset by the above electronic device; for example, the first setting coefficient may be 0.333.

[0150] For example, the calculation process of the color temperature index may be formula (2).

[0151]

[0152] Among them, γ low It can be a color temperature index, CCT0 can be a standard color temperature, CCT max Can be the first color temperature threshold, CCT min It can be the second color temperature threshold, and 0.333 is the first setting coefficient.

[0153] The process of obtaining the preset color temperature difference value may include: determining the color temperature difference value based on the standard color temperature, the first color temperature threshold, the second color temperature threshold, and the second setting coefficient.

[0154] Here, the second setting coefficient may also be a coefficient preset by the above electronic device; for example, the second setting coefficient may be 500.

[0155] For example, the calculation process of the color temperature difference value may be as shown in formula (3).

[0156]

[0157] Among them, △CCT low It can be a color temperature difference value, and 500 is the second setting coefficient.

[0158] In some embodiments, determining the first adjustment coefficient based on the first offset color temperature includes:

[0160] The first adjustment coefficient is determined based on a preset mapping relationship between the color temperature and the adjustment coefficient and the first target color temperature.

[0161] In this way, the first target color temperature can be determined by the sum of the first offset color temperature and the preset standard color temperature, and then the first adjustment coefficient can be determined by the mapping relationship between the preset color temperature and the adjustment coefficient and the first target color temperature to achieve subsequent adjustment of the initial color information, thereby better realizing the eye protection effect of the electronic device and improving the user experience and comfort.

[0162] Among them, the above-mentioned first target color temperature can be an eye-protection color temperature after adjusting the color temperature of the pixel points displayed on the above-mentioned screen.

[0166] It can be understood that based on the above-mentioned first target color temperature, the first adjustment coefficient corresponding to the first target color temperature is found from the mapping relationship between the preset color temperature and the adjustment coefficient, so that the initial color information can be subsequently adjusted according to the first adjustment coefficient to obtain the target color information.

[0167] Here, the process of obtaining the mapping relationship between the preset color temperature and the adjustment coefficient may include: determining multiple chromaticity coordinates corresponding to multiple preset color temperatures based on a preset color temperature trajectory function and multiple preset color temperatures; determining multiple preset adjustment coefficients corresponding to the multiple chromaticity coordinates based on the multiple chromaticity coordinates; determining the mapping relationship between color temperature and adjustment coefficient based on the multiple preset color temperatures and the multiple preset adjustment coefficients.

[0168] The color temperature trajectory function may include a daylight trajectory function and a black body trajectory function; the process of obtaining the preset color temperature trajectory function may include: determining the color temperature trajectory function based on the current time; the current time may include the current date and the current time. That is, during the day, multiple chromaticity coordinates may be determined using the daylight trajectory function and multiple preset color temperatures, and at night, multiple chromaticity coordinates may be determined using the black body trajectory function and multiple preset color temperatures.

[0169] For example, taking the daylight trajectory 4000K-7000K of CIE 2015 as an example, the daylight trajectory function may be formula (5).

[0170]

[0171] Among them, T d Can be preset color temperature, W xd Can be the x-coordinate of the chromaticity coordinate, W yd Can be the y coordinate of the chromaticity coordinate.

[0173] Table 1

[0174]

[0175]

[0176] The mapping relationship between a plurality of preset color temperatures and preset adjustment coefficients, ie, the mapping relationship between the preset color temperatures and the adjustment coefficients, can be obtained from Table 1 above.

[0177] It should be noted that the above-mentioned determination of the second adjustment coefficient based on the blue light ratio can be implemented in various different ways. The following are only examples and are not intended to be limiting.

[0186] In this way, the second color temperature coefficient can be determined first by the blue light proportion, the second blue light threshold, the preset maximum blue light proportion and the preset color temperature index, and then the second offset color temperature can be obtained by the second color temperature coefficient and the preset color temperature difference value, so as to determine the second adjustment coefficient in the subsequent process, and further realize the subsequent adjustment of the initial color information, so as to better realize the eye protection effect of the electronic device and enhance the user experience and comfort.

[0187] It can be understood that the process of obtaining the preset maximum blue light proportion may include: determining the blue light proportions of multiple samples corresponding to the multiple sample color information according to the multiple sample color information and the above blue light model; and selecting the maximum blue light proportion from the multiple sample blue light proportions. That is, multiple sample RGB values ​​are input into the above blue light model to obtain the blue light proportions of multiple samples corresponding to the multiple sample RGB values, and then the multiple sample blue light proportions are compared to obtain the above maximum blue light proportion.

[0188] For example, the color temperature index γ high The calculation process can be expressed as formula (6), the color temperature difference value △CCT high The calculation process of can be expressed as formula (7).

[0189]

[0190]

[0193] The second adjustment coefficient is determined based on a preset mapping relationship between the color temperature and the adjustment coefficient and the second target color temperature.

[0194] In this way, the second target color temperature can be first determined by the difference between the standard color temperature and the second offset color temperature, and then the second adjustment coefficient can be determined by the mapping relationship between the preset color temperature and the adjustment coefficient and the second target color temperature to achieve subsequent adjustment of the initial color information, thereby better realizing the eye protection effect of the electronic device and improving the user experience and comfort.

[0195] The second target color temperature may also be an eye-protection color temperature obtained by adjusting the color temperature of the pixels displayed on the screen.

[0196] For example, the calculation process of the second target color temperature may be formula (8).

[0197]

[0198] Among them, CCT2 can be the second target color temperature, △CCT high Can be the color temperature difference value, P high can be the second blue light threshold, P max can be the maximum blue light proportion, γ high Can be the color temperature index, can be the second color temperature coefficient, May be a second offset color temperature.

[0199] It can be understood that based on the above-mentioned second target color temperature, the second adjustment coefficient corresponding to the second target color temperature is found from the mapping relationship between the preset color temperature and the adjustment coefficient, so that the initial color information can be adjusted according to the second adjustment coefficient to obtain the target color information.
