Referring to fig. 2, fig. 2 is a flowchart illustrating a display control method according to a second embodiment of the present invention.
Based on the first embodiment described above, in the present embodiment, the step S10 includes:
step S101: when detecting that the wallpaper of the display interface is changed, selecting a plurality of sampling points corresponding to the target interface control on the changed wallpaper.
It should be understood that, selecting a plurality of sampling points corresponding to the target interface control on the changed wallpaper may be selecting a plurality of sampling points at a preset distance from the periphery of the target interface control, for example, selecting a plurality of sampling points at a preset number of pixels from the boundary of the target interface control.
It can be understood that the sampling points may be rectangular regions of m × n pixels, that is, the length of the rectangular region is m pixels, the width is n pixels, each sampling point has m × n pixels, and when m and n are 1, the sampling point only includes one pixel.
In a specific implementation, referring to fig. 3, taking a target interface control as an application card a as an example, 10 sampling points are selected on the changed wallpaper around the application card a, and distances between adjacent sampling points may be equal or different, which is determined according to an actual situation, and this embodiment is not limited thereto.
Step S102: and determining the color parameters of each sampling point according to the pixel information of each sampling point, and determining the color mean value of the changed wallpaper according to the color parameters of each sampling point.
It can be understood that the pixel information includes the number of pixel points of the sampling point and the RGB parameters of each pixel point; the color parameters may be RGB parameters of the sampling points; when m and n are 1, the RGB parameters of the pixel point are the color parameters of the sampling point; and when m and n are larger than 1, the average value of the RGB parameters of each pixel point in the sampling point is the color parameter of the sampling point.
It should be understood that after the color parameters, i.e., the RGB parameters, of each sampling point are determined, the RGB average values of all the sampling points can be obtained, and the color average value of the sampling points, i.e., the color average value of the changed wallpaper, can be obtained by adding and dividing 3 to the R value, the G value, and the B value of the RGB average values.
Step S103: and determining the characteristic color of the changed wallpaper according to the color parameters of the sampling points and the color mean value.
It should be understood that the determining of the characteristic color of the changed wallpaper according to the color parameter and the color mean value of each sampling point may be determining a deviation between the color parameter and the color mean value of each sampling point, then removing the sampling points whose deviations are greater than or equal to a preset deviation threshold, and finally averaging the RGB parameters of all the sampling points whose deviations are less than the preset deviation threshold to obtain an average RGB value, where the average RGB value is the characteristic color of the changed wallpaper.
Further, in order to ensure that the extracted characteristic color can accurately reflect the theme color of the changed wallpaper, so that the color style of the wallpaper and the color style of the target interface control are consistent, the step S103 includes: determining the color variance of each sampling point according to the color parameters of each sampling point and the color mean value; selecting characteristic sampling points with color variance smaller than a preset variance threshold from the plurality of sampling points to obtain a characteristic sampling point set; and determining the characteristic color of the changed wallpaper according to the average value of the color parameters of the characteristic sampling points in the characteristic sampling point set.
It can be understood that the color parameters include R values, G values, and B values, and the color variance is the variance between the R values, G values, and B values of the color parameters of each sampling point and the color mean; the preset variance threshold may be a preset threshold for selecting the feature sampling points.
It should be understood that when the color variance is smaller than the preset variance threshold, it indicates that the color of the sampling point is similar to the theme color of the changed wallpaper, and the corresponding sampling point is a feature sampling point; when the color variance is larger than or equal to a preset variance threshold value, the color of the sampling point is larger than the color difference of the wallpaper theme after the change, the corresponding sampling point is removed, and the characteristic sampling points form a characteristic sampling point set; and solving the average value of the color parameters of each characteristic sampling point in the characteristic sampling point set, wherein the solved average value is the characteristic color of the changed wallpaper.
In specific implementation, referring to fig. 4, for example, n sampling points are selected around an application card a, each sampling point includes m × n pixels, an RGB parameter of each sampling point and an RGB mean value of all pixel points are calculated, an average value of an R value, a G value, and a B value in the RGB mean value is obtained to obtain a color mean value of the wallpaper after change, a variance between each sampling point and the color mean value is determined according to the R value, the G value, and the B value in the RGB parameter of each sampling point, whether the variance is smaller than a preset variance threshold is judged, if yes, the sampling point is reserved as a characteristic sampling point, if not, the sampling point is extracted, finally, an average RGB value of all characteristic sampling points is calculated, extraction of a characteristic color is completed, and the average RGB value can represent the characteristic color of the wallpaper after change.
When detecting that the wallpaper of the display interface is changed, selecting a plurality of sampling points corresponding to the target interface control on the changed wallpaper; determining color parameters of each sampling point according to the pixel information of each sampling point, and determining the color mean value of the changed wallpaper according to the color parameters of each sampling point; and determining the characteristic color of the changed wallpaper according to the color parameters of the sampling points and the color mean value. According to the embodiment, a plurality of sampling points corresponding to the target interface control are selected from the changed wallpaper, the color parameters of the sampling points are determined according to the pixel information of the sampling points, the color mean value of the changed wallpaper is determined according to the color parameters, and the characteristic color of the changed wallpaper is determined according to the color parameters and the color mean value, so that the sampling points with large theme color deviation with the changed wallpaper can be removed, and the accuracy of characteristic color extraction is improved.
Referring to fig. 5, fig. 5 is a flowchart illustrating a display control method according to a third embodiment of the present invention.
Based on the above embodiments, in the present embodiment, the step S20 includes:
step S201: and determining the tone type of the changed wallpaper according to the characteristic color and a preset color threshold value.
It is understood that the preset color threshold may be a preset threshold for determining the wallpaper tone type; and when the average value of the R value, the G value and the B value of the RGB value of the characteristic color is larger than a preset color threshold value, judging that the tone type of the wallpaper is a light tone, and when the characteristic color is smaller than the preset color threshold value, judging that the tone type of the wallpaper is a deep tone.
Step S202: and selecting a corresponding color enhancement algorithm according to the tone type, and performing color enhancement on the characteristic color through the color enhancement algorithm.
It is understood that the color enhancement algorithm includes a brightness boosting algorithm and a brightness reduction algorithm; selecting a corresponding color enhancement algorithm according to the tone type, wherein when the tone type is a light tone, a brightness reduction algorithm is selected, and the brightness of the characteristic color is reduced through the brightness reduction algorithm; and when the tone type is a dark tone, selecting a brightness improvement algorithm, and improving the brightness of the characteristic color through the brightness improvement algorithm.
Step S203: and setting the characteristic color after the color enhancement as a control color parameter of a target interface control in the display interface.
As can be appreciated, the control color parameters include color parameters of the controls of the application card and the button color parameters of the navigation bar and status bar.
In the specific implementation, when the mean value corresponding to the characteristic color is greater than or equal to a preset color threshold value, the tone type of the wallpaper after being changed is judged to be light tone, and the brightness of the characteristic color is reduced through a brightness reduction algorithm; and when the mean value corresponding to the characteristic color is smaller than a preset color threshold value, judging that the color tone type of the wallpaper after being changed is a deep color tone, increasing the brightness of the characteristic color through a brightness increasing algorithm, and setting the characteristic color after brightness reduction or brightness increase as the color parameters of a control, a navigation bar and a status bar key of the application card.
Further, since the characteristic colors are divided into gray-scale colors and color colors, in order to improve the contrast between the control and the background in the target interface space, the step S202 includes: when the tone type is light tone, determining a feature color variance according to the feature color and the feature color mean value of the feature color; when the variance of the characteristic color is smaller than a preset threshold value, carrying out gray scale color brightness reduction on the characteristic color; and when the variance of the characteristic color is larger than or equal to a preset threshold value, reducing the color brightness of the characteristic color.
It is understood that the characteristic color mean value may be an average of R, G, and B values of the characteristic color; the variance of the characteristic color can be the variance of the R value, the G value and the B value of the characteristic color and the average value of the characteristic color; the preset threshold value can be a preset threshold value for judging whether the characteristic color is a gray scale color or a color; when the variance of the characteristic color is smaller than a preset threshold value, the characteristic color is judged to be gray-scale color, the brightness of the gray-scale color is reduced for the characteristic color, when the variance of the characteristic color is larger than or equal to the preset threshold value, the characteristic color is judged to be color, and the brightness of the color is reduced for the characteristic color.
In a specific implementation, referring to fig. 6, when the characteristic color is a light tone, determining whether a variance of the characteristic color is smaller than a preset threshold k, when the variance of the characteristic color is smaller than the preset threshold, determining that the characteristic color is a gray-scale color, performing gray-scale color brightness reduction on the characteristic color, when the variance of the characteristic color is greater than or equal to the preset threshold, determining that the characteristic color is a color, and performing color brightness reduction on the characteristic color; the reduction of the color brightness and the reduction of the gray-scale color brightness can be referred to tables 1 and 2, wherein a is a brightness attenuation coefficient in the range of (0,1), and the intensified color is a characteristic color after the brightness reduction.

| Characteristic color | R | G | B |
| Accent color | (1-a)*R | (1-a)*G | (1-a)*B |
Further, since the characteristic colors are divided into gray-scale colors and color colors, in order to improve the contrast between the control and the background in the target interface space, the step S202 includes: when the tone type is a dark tone, determining a feature color variance according to the feature color and the feature color mean value of the feature color; when the variance of the characteristic color is smaller than a preset threshold value, carrying out gray scale color brightness improvement on the characteristic color; and when the variance of the characteristic color is larger than or equal to a preset threshold value, carrying out color brightness improvement on the characteristic color.
