Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flowchart of a screen color adjustment method according to an embodiment of the present invention, which is applied to a mobile terminal. The implementation process of this method will be described in detail below with respect to this figure.

Step 101 , detecting whether the background color of the fixed content display area matches the background color of the variable content display area in the display interface of the screen.

Here, the mobile terminal has a super high screen-to-body ratio. It can also be understood that the screen of the mobile terminal is a full screen.

Here, preferably, the fixed content display area is the area where the virtual navigation bar is located. In other words, the virtual navigation bar is set within the screen, not below the screen.

It should be noted that the color matching of the two areas means that the color values of the pixels in the two areas are the same or the difference between the color values is within a predetermined range.

Here, the color value of the pixel includes: RGB (Red Green Blue, Red Green Blue) color value, CMY (cyan Magenta Yellow, Cyan Magenta Yellow) color value, and the like.

For example, when the difference between the color value of the R component of the pixel in the first area and the color value of the R component of the pixel in the second area is within the first threshold range, and the color value of the G component is different from the color of the G component of the pixel in the second area The two region colors match when the difference of values is within a second threshold range and the difference between the color value of the B component and the color value of the B component of the pixels in the second region is within a third threshold range.

Here, the specific processing procedure of using the CMY color value as the judgment basis for determining whether the colors of the two regions match can refer to the above example, and will not be repeated here.

Step 102, if not, acquire the background color of the preset area in the variable content display area.

Here, the preset area is an adjacent area of the fixed display area. In this way, the background color of the preset area is the background color of the adjacent area of the fixed display area, which is convenient for subsequent adjustment of the background color of the fixed display area according to the background color of the adjacent area, which is conducive to the smooth transition of colors and ensures the coordination and unity of the overall screen display .

Here, further, if the background color of the fixed content display area matches the background color of the variable content display area, no processing is performed on the background color of the fixed content display area in the display interface. That is to say, the background color of the fixed content display area in the display area remains unchanged.

Step 103, performing color selection processing on the background color of the preset area to obtain a target color.

Here, the background color of the preset area may be a single color or a variable color. The purpose of performing color picking processing on the background color of the preset area is to obtain the optimal color, that is, the target color, so that after the subsequent screen color is adjusted according to the optimal color, the overall screen display effect is coordinated and unified.

Step 104, replacing the background color of the fixed content display area with the target color.

In the screen color adjustment method provided by the embodiment of the present invention, when it is detected that the background color of the fixed content display area in the display interface of the screen does not match the background color of the variable content display area, by adjusting the acquired variable content display area The background color of the preset area is color-picked to obtain the target color, and the background color of the fixed content display area is replaced with the target color, so that the background color of the display interface of the entire screen is coordinated and unified, and the display effect of the screen interface is improved. The full-screen immersive experience of the screen mobile terminal improves the user's visual experience.

Step 1011, acquiring a screenshot of the first partial area of the fixed content display area and a screenshot of the second partial area of the variable content display area.

Specifically, the area size of the fixed content display area and the variable content display area to be captured can be set through software; after that, according to the set area size, obtain the screenshot of the first part of the fixed content display area and the variable content A screenshot of the second part of the display area.

It should be noted that the area size of the first partial area screenshot and the second partial area screenshot corresponds to the area size set by the previous software.

Step 1012, judging whether the difference between the first color value of the screenshot of the first partial area and the second color value of the screenshot of the second partial area is within a preset threshold range.

Here, preferably, both the first color value and the second color value are RGB color values.

Step 1013, if the difference between the first color value and the second color value is greater than within the preset threshold range, then determine the background color of the fixed content display area and the variable content display area The background color does not match.

On the basis of the embodiment shown in FIG. 1 above, as a preferred implementation, step 102 of the present invention may include:

Identifying a preset area within the variable content display area that is greater than zero and less than or equal to preset pixel heights from the fixed content display area; acquiring the background color of the preset area.

Here, preferably, the preset area is an area within the variable content display area that is greater than zero and less than or equal to 2 pixel heights from the fixed content display area.

Of course, the height of the preset area is not limited to 2 pixels, and can be set according to specific situations.

On the basis of the above-mentioned embodiment shown in FIG. 1, as a preferred implementation, as shown in FIG. 3, step 103 of the present invention may include:

Step 1031, acquiring the color value of each sampling pixel in the preset area;

Specifically, the preset area is evenly divided into a plurality of sub-areas, and the pixels in each sub-area are sampled; the color value of each sampled pixel in each sub-area is acquired.

Here, the sampling pixels are discrete pixel points in the preset area.

It should be noted that the color values of each sampling pixel are RGB color values.

Step 1032, based on the normal distribution function of the color values of each sampled pixel, perform color selection processing on the background color of the preset area to obtain the target color.

Here, the random variable of the normal distribution function is the color value of the sampled pixel.

Preferably, this step may specifically include:

calculating an average value and a variance of the color values of the sampling pixels according to the color values of each sampling pixel;

Here, the variance of the color value of each sampled pixel can be calculated according to the difference between the average value and the color value of each sampled pixel.

Here, the variance of the color value of each sampled pixel refers to the average number of the sum of squares of differences between the color value of each sampled pixel and the average value of the color values of all sampled pixels.

That is to say, after calculating the difference between the average value and the color value of each sampled pixel, they are squared separately, summed and then averaged.

According to the normal distribution function of the color values of each sampled pixel corresponding to the average value and variance, the background corresponding to the area whose probability of falling within the interval of the normal distribution function in the preset area is a preset value The color is determined as the target color.

Here, preferably, the preset value is 80%.

Here, through the above-mentioned color picking process of steps 1031 to 1032, the optimal color for replacing the fixed display area, that is, the target color is obtained. After the subsequent screen color is adjusted according to the optimal color, the overall screen display effect is coordinated and unified.
