The method for changing the background of the terminal equipment is applied to the terminal equipment with the graphical user interface, such as a mobile phone, a computer and the like, which finally realize information interaction with people, wherein the application background of the terminal equipment can be automatically changed according to the current preview picture of the user. The method comprises the steps that a terminal device calculates the color deviation ratio of a current frame image and a previous frame image of a video image by acquiring the current frame image and the previous frame image of the video image, judges whether the color deviation ratio is larger than a first preset threshold value, extracts the current frame image and generates a first picture as a background of an application under the condition that the color deviation ratio is larger than the first preset threshold value; and under the condition that the color deviation ratio is smaller than or equal to a first preset threshold value, the application background is not changed. The video image may be a video image stored by the terminal device itself or a video image of another place monitored by the current terminal device in real time, and it should be noted that the video image in the present application includes a still image and a moving image.
The present embodiment provides a method for changing the background of a terminal device, fig. 1 is a flowchart of a method for changing the background of a terminal device according to an embodiment of the present application, as shown in fig. 1, and the method includes the following steps:
step S101, acquiring a current frame image and a previous frame image of a video image;
for the user operation, the current frame image and the previous frame image of the video image may be acquired under the condition that any video image in the terminal device is opened, and it is noted that the current frame image and the previous frame image of the video image may be two adjacent frame images.
Step S102, calculating the color deviation ratio of the current frame image and the previous frame image;
note that, the colors of the current frame image and the previous frame image are recorded and expressed by RGB values. All colors in a video image are mixed by the three colors of red, green and blue according to different proportions, and the so-called "how much" of RGB refers to brightness and is expressed by integers. Typically, RGB has 256 levels of brightness each, indicated by numerals from 0, 1, 2. Note that although the number is 255 at the highest, 0 is also one of the values, thus 256 stages in total; as calculated, 256 levels of RGB colors can combine a total of about 1678 tens of thousands of colors, i.e., 256×256×256=16777216, also commonly referred to as 1600 tens of thousands of colors or tens of millions of colors for short.
Step S103, judging whether the color deviation ratio is larger than a first preset threshold value, and extracting a current frame image and generating a first picture under the condition that the color deviation ratio is larger than the first preset threshold value;
when the color deviation ratio is larger than a first preset threshold, the current frame image can be triggered to be intercepted, the intercepted current frame image is a first picture, and when the color deviation ratio is smaller than or equal to the first preset threshold, the terminal equipment can not be triggered.
Step S104, generating the background of the application according to the first picture.
Through steps S101 to S104, under the condition that any video image in the terminal device is opened, the current frame image and the previous frame image of the video image can be obtained, the color deviation ratio of the current frame image and the previous frame image is calculated based on the RGB value mode, under the condition that the color deviation ratio is greater than a first preset threshold value, the current frame image can be triggered to be intercepted, a first picture is generated by the intercepted current frame image, and then the first picture is set as the background of the application of the terminal device, so that the application background of the terminal device can be automatically changed according to the picture currently previewed by the user, the problem that the preset background matches the current application of the terminal device and the matching degree is low is solved, and the matching degree of the application background of the terminal device is improved.
In some of these embodiments, fig. 2 is a flowchart of a method for generating an interface background of an application from a first picture according to an embodiment of the present application, as shown in fig. 2, the method comprising the steps of:
step S201, blurring the first picture through a blurring model to generate a second picture;
the blurring model is a process of resetting each pixel value in the first picture, which is to set each pixel to be an average value of surrounding pixels. It should be noted that, for each pixel being processed, the RGB values of the surrounding pixels are taken and averaged, and then this average value is the blurred processed pixel, and if all pixels in the first picture are so processed, the processed picture becomes blurred.
However, if the first picture color changes frequently and the color contrast per unit area is large and the blur radius is large, the result is: the weights of the pixels at the outermost layer of the blurring range and the pixels around the central pixel are the same, so that the first picture processed has the problem that the transition is not very smooth. Therefore, a gaussian blur algorithm is required to calculate weights for these pixels in the blur range separately, so that the lower the pixel weight at the periphery of the blur radius, the less impact is caused, and the more inside pixels get the highest weight, because the inside pixels are more important, the color of the inside pixels is closer to the first picture center pixel, and more closely.
Step S202, generating an interface background of the application according to the second picture;
and setting the second picture subjected to blurring processing as an interface background of the application.
Through steps S201 to S202, the second picture obtained after the first picture is subjected to blurring processing, and the second picture is generated into an applied interface background, in which case the applied interface background can be automatically changed according to the picture currently previewed by the user, and the interface background finally presented by the second picture after the blurring effect can be contrasted with the picture currently browsed by the user, so that the picture currently browsed by the user can be highlighted.
In some of these embodiments, fig. 3 is a flowchart of a method for generating a button background of an application from a first picture according to an embodiment of the present application, as shown in fig. 3, the method comprising the steps of:
step S301, extracting a color value of each pixel point in the first picture;
pixels are defined as being made up of tiles of the image, each of which has a definite position and assigned color value. The 256-level RGB colors can be combined to form about 1678 ten thousand colors, and the color value of each pixel point in the first picture is the specific color of 1678 ten thousand colors corresponding to each pixel point in the first picture, and it should be noted that the specific size of the color value corresponding to each pixel point can represent the color corresponding to each pixel point.
In step S302, an average value of the color values is calculated.
Step S303, calculating a counter value of the average value, and generating an applied button background by the counter value;
and averaging the color values corresponding to the pixel points in the first picture to obtain an average value related to the color values of the first picture, calculating the counter value of the average value, and finally generating the counter value into the button background for application, for example, the color represented by the average value is black, so that the color represented by the counter value of the average value is white, and finally generating the white into the button background for application.
Through steps S301 to S303, the color value of each pixel point in the first picture is extracted, and then the color corresponding to the final color value is generated to be applied to the button background, in this case, the applied button background can be automatically changed according to the picture currently previewed by the user, and the finally generated button background can form contrast with the currently browsed picture, so that the button background is more prominent in the browsed picture.
In some embodiments, the method flowchart of generating the background of the application according to the first picture may also include a combination of the generating interface background of step S201 to step S202 and the generating button background of step S301 to step S303.
In some of these embodiments, fig. 4 is a flowchart of another method of generating a button background of an application from a first picture according to an embodiment of the present application, as shown in fig. 4, the method comprising the steps of:
step S401, extracting a color value of each pixel point in the first picture;
the step S401 and the step S301 are the same operations, and are not described herein.
Step S402, calculating the number of pixels corresponding to each color value;
and calculating the number of pixel points corresponding to each color value in the first picture, for example, the color value of blue is 255 in RGB color values, and statistically obtaining 1000 pixels of blue 255 in the first picture.
Step S403, sorting according to the number of pixels corresponding to the color values, and obtaining the color value with the maximum number of pixels;
according to the number of pixels corresponding to each color value, the color values with the largest number of pixels can be obtained by sorting from small to large or from large to small, and it is further required to explain that the color value with the largest number of pixels can represent the dominant color value in the first picture.
Step S404, calculating the inverse value of the color value with the largest number of pixel points, and generating the inverse value into the applied button background;
the color represented by the color value of the dominant color in the first picture is black, so that the color represented by the color value of the dominant color in the first picture is white, and finally the white is generated into the button background of the application.
Through steps S401 to S404, the number of pixels corresponding to the color values is ordered, the color value with the largest number of pixels is obtained, the color value which can represent the dominant color value in the first picture is obtained, the inverse value of the dominant color value is calculated, the inverse value of the dominant color value in the first picture is finally set as the button background of the application, and the generated button background forms larger contrast with the currently browsed picture under the condition that the button background of the application can be automatically changed according to the picture currently previewed by the user, so that the button background is more prominent in the browsed picture.
In some embodiments, the method flowchart of generating the background of the application according to the first picture may also include a combination of the generating interface background of step S201 to step S202 and the generating button background of step S401 to step S404.
In some embodiments, fig. 5 is a second flowchart of a method for changing a background of a terminal device according to an embodiment of the present application, as shown in fig. 5, before calculating the number of pixels corresponding to each color value, the method further includes the following steps:
step S501, obtaining the category number of the color values;
before calculating the number of pixels corresponding to each color value, the number of categories of the color value in the first picture is counted, and it is to be noted that the number of categories represents how many colors are in the first picture, for example, 10000 colors are in the first picture.
Step S502, judging whether the number of categories is larger than a second preset threshold, gathering the colors with similar color values under the condition that the number of categories is larger than the second preset threshold, taking the average color value as the color value of the category, and calculating the number of pixel points corresponding to each color value under the condition that the number of categories is smaller than or equal to the second preset threshold;
counting the number of categories of the colors in the first picture, gathering or combining the colors with similar colors under the condition that the number of categories of the colors in the first picture is larger than a second preset threshold value, averaging the sizes of the color values, and taking the average color value as the color value of the category, wherein the description is needed. For example, the color values 233, 234, 235, 236, 237, 238 and 239 are similar, and the average value is calculated to obtain 236, so that the categories 233, 234, 235, 236, 237, 238 and 239 are classified into the category of the color values represented by 236, and the number of the color categories in the first picture is reduced.
Through step S501 to step S502, it is determined whether the color values in the first picture are scattered, if the color values are scattered, and the color value category exceeds the set threshold, the average color value is taken as the color value of the category through similar color grouping, so that the problem of missed main tone calculation deviation caused by too much scattering of the color is avoided, and further, the matching precision of the button background is improved.
Fig. 6 is a flowchart of a method of calculating a color deviation ratio of a current frame image to a previous frame image according to an embodiment of the present application, as shown in fig. 6, the method comprising the steps of:
step S601, obtaining color values of N points with the same coordinates from a current frame image and a previous frame image, wherein the N points are distributed in different areas of the current frame image;
it should be noted that, the specific size of N needs to be valued according to the number of pixels in the adjacent frame image, for example, the current frame image is 10000 pixels, N is 2000, the current frame image is 100 ten thousand pixels, N is 20 ten thousand, and optionally, the value of N may be 5% -30% of the number of pixels in the current frame image or the previous frame image.
In step S602, the number of color value changes is counted.
Step S603, calculating the number of duty ratios, wherein the duty ratio indicates the color deviation ratio of the current frame image and the previous frame image;
the calculated number of the duty ratio refers to the calculated number of the color value change which is the percentage of N, and it should be noted that the first preset threshold may be 20%, or a deviation of points exceeding a specific percentage may be set according to actual requirements, so that the application background may be considered to be replaced.
Through steps S601 to S603, the number of pixels in a certain proportion is selected according to the number of pixels in the current frame image or the previous frame image, so as to determine the duty ratio of the change of the color values of the number of pixels in the current frame image and the previous frame image, where the duty ratio is used to indicate the color deviation ratio of the current frame image and the previous frame image, so as to improve the calculation accuracy of the color deviation ratio.
In some embodiments, fig. 7 is a flowchart III of a method for changing the background of a terminal device according to an embodiment of the present application, and before generating the background of an application according to a first picture, as shown in fig. 7, the method further includes the following steps:
step S701, judging whether the size of the first picture is matched with the display size of the terminal equipment;
alternatively, the size of the first picture may be a width value and a height value of the first picture, and the display size of the same terminal device may be a width value and a height value of the display.
Step S702, scaling the first picture to the display size if the first picture does not match the display size;
when the width value and the height value of the first picture do not match the width value and the height value of the display size, the first picture may be scaled equally until it matches the display width value and the height value of the terminal device.
Through step S701 and step S702, before the first picture generates the background of the application, the first picture is scaled to a width value and a height value that match the display size, where it should be noted that, a manner of scaling the first picture may be, but is not limited to, a manner of clipping, for example, clipping the first picture to a size displayed by the terminal device, so that the pixel density of the image may be reduced, the calculation speed may be increased, and the size matching degree of the first picture as the application background may be improved.
