Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an object display method according to an embodiment of the present invention. The embodiment can be applied to the condition of clearly displaying the object to be displayed in the current video picture, and is particularly suitable for the condition of clearly displaying the object to be displayed in the current video picture in a transparent video mode. The method can be executed by the object display device provided by the embodiment of the invention, the device can be realized by software and/or hardware, and the device can be integrated on various user terminals or servers.
Referring to fig. 1, the method of the embodiment of the present invention specifically includes the following steps:
s110, when a trigger event of a display object is monitored, a video to be displayed corresponding to the trigger event and a preset display area of the video to be displayed in a current video picture are obtained.
When the current video picture is being played and a trigger event of the display object is monitored, the object to be displayed corresponding to the trigger event can be determined according to the trigger event, and the video to be displayed of the object to be displayed and the preset display area of the video to be displayed in the current video picture are obtained. The object to be displayed may be an object with a small volume in the current video picture, or may be an object outside the current video picture; the video to be displayed can provide a display close-up for the object to be displayed so as to clearly display the object to be displayed. On the basis, on one hand, as the video to be displayed is a streaming media, when the video to be displayed is loaded into the memory, all video frames do not need to be loaded, and only a few frames of video frames which can be smoothly played by the video to be displayed need to be sequentially loaded, so that the memory can be saved; on the other hand, as the video to be displayed is composed of a plurality of frames of pictures to be displayed, a string of continuous contents of the object to be displayed can be displayed instead of a single content, which can improve the user experience.
On the basis, the video to be displayed can be obtained in advance in multiple modes, and an optional technical scheme is adopted to obtain the video to be adjusted of the object to be displayed, adjust the transparency of each pixel point to be adjusted in the background content of the video to be adjusted, and construct the video to be displayed according to the adjustment result.
The video to be adjusted is an original close-up video of the object to be displayed without any processing, and the problem that the object to be displayed cannot be clearly displayed can be solved if the video to be adjusted is directly displayed on the current video picture, but a certain display area of the current video picture can be blocked; moreover, if the content including the object to be displayed in the video to be adjusted is taken as foreground content and the content not including the object to be displayed is taken as background content, the foreground content is the key content for clearly displaying the object to be displayed. Therefore, the transparency of each pixel point to be adjusted in the background content of the video to be adjusted can be adjusted, for example, the transparency is reduced, even the transparency is set to be full transparency, and the video to be displayed is constructed according to the adjustment result, so that the video to be displayed only can display the object to be displayed on the current video picture and can not display the content except the object to be displayed, and the content blocked in the current video picture can be reduced as much as possible.
And S120, displaying the video to be displayed on a preset display area, wherein the foreground content of the video to be displayed comprises an object to be displayed and the background content is transparent content.
The video to be displayed is displayed on the preset display area, and the preset display area of each video to be displayed can be the same or different. Aiming at displaying a video to be displayed in a preset display area, namely, overlapping the video to be displayed on the preset display area of a current video picture, the area outside the preset display area of the current video picture is only used for displaying the current video picture, the preset display area is used for displaying the current video picture at the bottom layer and displaying the video to be displayed at the top layer, and the background content of the video to be displayed cannot shield the current video picture because of being transparent.
According to the technical scheme of the embodiment of the invention, when the trigger event of the display object is monitored, the to-be-displayed video corresponding to the trigger event and the preset display area of the to-be-displayed video in the current video picture are obtained, so that when the to-be-displayed video is displayed in the preset display area, a close-up display is provided for the to-be-displayed object because the foreground content of the to-be-displayed video comprises the to-be-displayed object, and excessive current video picture cannot be blocked because the background content of the to-be-displayed video is transparent. The technical scheme solves the problem that the object to be displayed in the current video picture cannot be clearly displayed, and meanwhile, the effect of saving the memory and displaying a string of consecutive contents of the object to be displayed is achieved because the video to be displayed is streaming media, so that the experience of a user is improved to a greater extent.
A selectable technical solution is to obtain a video to be displayed corresponding to a trigger event, and specifically may include: acquiring a to-be-processed video corresponding to a trigger event, reading to-be-processed pixel information of each to-be-processed pixel point in the to-be-processed video, and if the to-be-processed pixel point is judged to belong to the background content of the to-be-processed video according to the to-be-processed pixel information, adjusting the transparency of the to-be-processed pixel information; otherwise, acquiring an original video of the video to be processed, and adjusting the pixel information to be processed according to the target pixel information of the target pixel point corresponding to the pixel point to be processed in the original video; and constructing the video to be displayed according to the adjustment result of the video to be processed.
The trigger event and the object to be displayed may have a one-to-one correspondence relationship, the object to be displayed and the video to be processed may have a one-to-one correspondence relationship, and the object to be displayed and the original video may also have a one-to-one correspondence relationship, and the original video may be an original close-up video of the object to be displayed without any processing. Therefore, after the to-be-processed video corresponding to the trigger event is acquired, the to-be-processed pixel information of each to-be-processed pixel point in the to-be-processed video can be read, for example, the to-be-processed pixel information of each to-be-processed pixel point in the to-be-processed video is read through a preset shader, and whether the to-be-processed pixel point belongs to foreground content or background content of the to-be-processed video can be judged according to the to-be-processed pixel information, wherein the foreground content of the to-be-processed video includes an object to be displayed and the background content does not include the object to be displayed.
On the basis, the transparency of the to-be-processed pixel points belonging to the background content in the to-be-processed video can be adjusted to obtain the transparent background content. Meanwhile, aiming at the pixel points to be processed belonging to the foreground content in the video to be processed, the original video of the video to be processed is obtained by taking the object to be processed as a medium, the pixel information to be processed is adjusted according to the target pixel information of the target pixel points corresponding to the pixel points to be processed in the original video, and for example, the color to be processed and/or the transparency to be processed of the pixel information to be processed can be adjusted according to the target color and/or the target transparency of the target pixel information. In this way, the video to be displayed can be constructed according to the adjustment result of the video to be processed, that is, the adjusted video to be processed is taken as the video to be displayed.
It should be noted that, since the to-be-processed video may be composed of multiple frames of to-be-processed pictures, after the to-be-processed video corresponding to the trigger event is obtained, the to-be-processed video may be decomposed into multiple frames of to-be-processed pictures, the to-be-processed pixel information of each to-be-processed pixel point in each frame of to-be-processed picture is read with the to-be-processed picture as a unit, and corresponding processing is performed on the to-be-processed pixel point by determining whether each to-be-processed pixel point in each frame of to-be-processed picture is a pixel point of foreground content or background content.
The video to be processed can be obtained in advance through the following steps: the method comprises the steps of obtaining an original video, extracting foreground content and background content of the original video, and converting the original video into a to-be-processed video according to an extraction result, wherein foreground pixel information of each foreground pixel point in the foreground content of the to-be-processed video is a preset foreground color, and background pixel information of each background pixel point in the background content of the to-be-processed video is a preset background color.
The original video may be an original close-up video without any processing of an object to be displayed, the video to be processed is equivalent to a two-color video, foreground content and background content of the video are different colors, illustratively, foreground pixel information of each foreground pixel point in the foreground content of the two-color video is white, and background pixel information of each background pixel point in the background content is black. The method for converting the original video into the bicolor video has the advantages that when the trigger event of the display object is monitored, the foreground content and the background content of the bicolor video can be simply divided according to the acquired color information of the bicolor video, so that the foreground content and the background content can be correspondingly processed to obtain the video to be displayed.
It should be noted that there are many ways to extract foreground content and background content of an original video, and an optional way, considering that color information of an object to be displayed in each original video tends to be consistent, if the color information of the object to be displayed is mainly red and the color information of the object to be displayed is mainly green, histogram statistics can be performed on the original pixel information of each original pixel point in the original video to obtain a statistical result of the color information, and the pixel point corresponding to the color information occupying the main proportion is taken as a foreground pixel point of the foreground content; on the basis, edge detection can be performed on the original video, and the original video can be better segmented by combining the histogram statistical result and the edge detection result. For example, if the color information of the object to be displayed is mainly red, the pixel point of which the color information is red may be extracted first, and then the original video segmentation is implemented by combining the edge delineation result of the object to be displayed.
In order to better understand the specific implementation process of the above steps, the following takes a pet in the game video screen of the background art as an example to describe the object display method of the present embodiment. For example, as shown in fig. 2a-2c, each pet skill corresponds to a to-be-processed video (as shown in fig. 2 b), which is a two-color video converted from the original video (as shown in fig. 2 a), wherein each foreground pixel in the foreground content is a predetermined foreground color (e.g., white) and each background pixel in the background content is a predetermined background color (e.g., black).
On the basis, when a trigger event for displaying the pet skill is monitored during the running of the game, a to-be-processed video of the pet skill to be displayed is obtained, and the to-be-processed video is decomposed into a plurality of frames of to-be-processed pictures; for each frame of picture to be processed, reading color information of each pixel point to be processed in the video to be processed through a preset shader so as to divide the video to be processed into foreground content (namely pet skill to be displayed) and background content (such as various ornaments, such as feathers, flowing lines and the like); setting each foreground pixel point in the foreground content as a target pixel point at a corresponding position in the original video, and setting the transparency of each background pixel point in the background content as full transparency, so as to obtain a video to be displayed with transparent background (as shown in fig. 2 c); further, the to-be-displayed videos are displayed on a preset display area of a game video interface, under the premise that the pet is normally used, the to-be-displayed videos with transparent background contents can provide an animation close-up for the skill of the pet to be displayed on the game video interface, so that the effect of displaying the pet large move through the playing of the transparent videos is achieved, the expressive force of the pet during the releasing period of the large move is improved, and the expressive effect of the pet skill is enhanced. That is, an animation video through which the coherent content of the pet during the release of the bouquet is presented on the game video screen, and the periphery of the animation video is transparent but the pet is not, which can achieve the effect of clearly presenting both the skill of the pet and the game video screen.
