Fig. 5 is a flowchart of a wallpaper generation method according to a fourth embodiment of the present invention, where the wallpaper generation method is refined based on any optional technical solution in the fourth embodiment of the present invention. Optionally, the generating a target display wallpaper based on the color switching parameter and the current display wallpaper includes: determining at least one frame of wallpaper to be switched corresponding to the current displayed wallpaper in the target wallpaper video; analyzing the wallpaper to be switched to obtain foreground texture data with an Alpha channel, and generating background texture data based on the color switching parameters; and fusing the foreground texture data and the background texture data to obtain the target display wallpaper.
As shown in fig. 5, the method of this embodiment includes the following specific steps:
s510, the wallpaper player receives a background switching request which is sent by the client and used for switching a wallpaper background of the wallpaper displayed currently in the wallpaper video, wherein the background switching request carries a color switching parameter of a target background color.
S520, the wallpaper player analyzes the background switching request to obtain the color switching parameter.
S530, determining at least one frame of wallpaper to be switched corresponding to the current displayed wallpaper in the target wallpaper video.
The wallpaper to be switched can be understood as the wallpaper which is analyzed from the target wallpaper video and is to be switched into the target background color based on the background switching request. In the embodiment of the invention, the background switching request can be only used for requesting to switch the wallpaper background which is the same as the current display wallpaper in the target wallpaper video, and can also be used for switching the wallpaper backgrounds of two or more wallpapers related to the current display wallpaper in the target wallpaper video. Therefore, the wallpaper to be switched can be one frame, two frames or more than two frames. The wallpaper to be switched may be a wallpaper currently being played in the target wallpaper video, that is, a wallpaper in the target wallpaper video that is the same as the currently displayed wallpaper, may also be a wallpaper in the target wallpaper video that has wallpaper playing time after the playing time of the currently displayed wallpaper (that is, the current playing time), and may also be a wallpaper in the target wallpaper video that has main information that is the same as the currently displayed wallpaper, and the like.
The wallpaper player can decode a target wallpaper video currently used by a user into a continuous multi-frame image sequence arranged according to a time sequence, and further determine the wallpaper to be switched, corresponding to the currently displayed wallpaper, in the target wallpaper video. The format of the video decoding may be an RGB format, a YUV format, or the like.
Optionally, at least one frame of wallpaper to be switched corresponding to the currently displayed wallpaper in the target wallpaper video may be determined based on a preset switching rule. The switching rule may be set according to actual requirements, a fixed switching rule may be set, or different switching rules may be set correspondingly based on different triggering manners, and the number of the switching rules or the switching manner is not specifically limited herein.
S540, analyzing the wallpaper to be switched to obtain foreground texture data with an Alpha channel, and generating background texture data based on the color switching parameters.
Where Alpha generally refers to the transparency and translucency of an image. The foreground texture data may be information that is desired to be preserved in the wallpaper to be switched, and may include, but is not limited to, a target subject in the wallpaper to be switched and dark part information in the image. The target subject can be automatically set by the system or can be specified by the user, specifically, the target subject can be the contents of people, buildings, landscapes and the like in the image and can be located at any position in the image. The dark part information may be understood as a part of the wallpaper to be switched with a darker brightness compared to the reference brightness, for example, may be dark corner information of the wallpaper to be switched. The advantage of providing the wallpaper with a dark portion is that the light change condition of the actually shot image can be simulated more realistically. The background texture data may be understood as the part of the wallpaper to be switched other than the foreground texture data.
The wallpaper player can analyze the target wallpaper video to obtain the foreground part and the background part of the wallpaper to be switched. For example, the analysis mode may be video decoding, the video may be decoded into a frame image by video decoding, and the format of the decoded image data may be RGB format. Optionally, the foreground part after video parsing is a background texture image with color switching parameters and a foreground texture image with an Alpha channel.
Optionally, generating background texture data based on the color switching parameter includes: and coloring a preset transparent background based on the color switching parameter to generate background texture data of the target background color. The generated background texture data may be, for example, pure color image data with RGB values, preset transparent background image data without any color, or any other image data with water ripples, light and dark stripes, texture data, and the like.
The wallpaper player can receive a color switching parameter obtained by converting a target background color in a client color space, and further utilize functional software generated by the target background, such as DX11 drawing software, to color a preset transparent background into a new background color based on the color switching parameter, so as to generate background texture data corresponding to the target wallpaper video and the background switching request.
And S550, fusing the foreground texture data and the background texture data to generate target display wallpaper.
Specifically, the background texture data and the foreground texture data obtained through analysis by the wallpaper player can be regarded as two images, and the two images can be fused into one image as a target display wallpaper by using image fusion software. Illustratively, when generating the target display wallpaper, color space fusion in a pixel level fusion method may be adopted, different color channels are utilized to map the background texture data and the foreground texture data to a special color channel respectively, and the colors of the channels are merged to enhance the visibility of the image color. The overlapped part of the background texture data and the foreground texture data can mix two colors through a color channel to generate a new color, and can also retain the foreground texture data and only display the color of the foreground texture data.
And S560, the wallpaper player feeds the target display wallpaper back to the client side so that the target client side can display the target display wallpaper.
According to the technical scheme, the wallpaper to be switched corresponding to the currently displayed wallpaper in the target wallpaper video is determined, that is, the switching requirements of the target user are fully considered, and all wallpapers to be switched can be accurately acquired. And then analyzing the wallpaper to be switched to obtain foreground texture data with an Alpha channel so as to reserve an original foreground part, generating background texture data based on color switching parameters, namely generating a background part with a target background color, then fusing the foreground texture data and the background texture data to generate target display wallpaper which only changes the background of the wallpaper without changing the foreground content of the wallpaper, and finally feeding the target display wallpaper as a feedback result to a client by a wallpaper player for displaying the target display wallpaper by the client, thereby realizing switching of the background wallpaper.
