[0028] In order to solve the above problems, an embodiment of the present disclosure provides a video mask layer display method, which is described below with specific examples.

[0029] Fig. 1 is a schematic diagram showing a flow of an animated mask layer display method according to an embodiment of the present disclosure. The method can be performed by an animated mask layer display device, where the device can be implemented in software and / or hardware, and can be generally integrated into electronic equipment. As shown in Fig. 1, the method includes the following steps:

[0030] Step 101: Determine a mask layer region in a video frame, where the mask layer region includes a first region matching a prominently displayed target information and a second region color-transitioning from the first region to another video screen not having the mask layer region.

[0031] Information can be added to a video, for example, video description information of a video. However, in some application scenarios, the color of the video screen and the color of the information added to the video are highly similar, and the information added to the video cannot be displayed clearly. Therefore, when a user views a video, in order to improve the viewing effect of the information added to the video frame, it is necessary to perform a masking process on the information added to the video frame. Since the color of the video screen to which the mask layer is added changes, the information added to the video can be displayed clearly due to the prominence of the mask layer.

[0032] Depending on the needs, various types and colors of information may be added to the video, such as the subject information of the video, description information, interaction information with the user, and / or effect information added to the video by an application program, music information, and the like. Depending on the needs, the colors used for different types of information and the positions added to the video screen may be dynamically designed, changed, and adjusted. Therefore, depending on the needs of different scenarios, all additional information may be masked to make the display stand out, or only some additional information may be masked to make the display stand out. In the embodiment of the present disclosure, additional information that needs to be masked to make the display stand out in the video is set as target information. Note that there are multiple methods for determining target information, and it may be selected according to the application scenario, and this embodiment does not impose any restrictions. In order to more clearly understand how to determine target information that needs to be masked to make the display stand out, an example will be described below.

[0033] In an optional embodiment, the target information is text information that matches a preset information type on the video frame screen. As can be seen, a video frame screen may have multiple information types, such as creator name, effect name, video description, song name, etc. For different information types, users have different viewing and viewing needs. For example, when a user views a video frame, he or she places more importance on viewing the video description information of the video. Therefore, depending on the needs, a type of information that requires a process of masking to make the display stand out may be preset, and additional information that matches the preset information type may be obtained from the information added to the video and used as the target information. For example, when the preset information type is video description information, it is determined that the video description information is the target information that requires a process of masking to make the display stand out from all the additional information added to the video.

[0034] In another optional embodiment, the target information is text information or code information that matches a preset color identification on the video frame screen. Depending on the needs, a color identification that requires processing to make the display stand out by masking may be preset, and additional information that matches the preset color identification may be obtained from information added to the video and used as the target information. For example, if the preset color identification is white, it is determined that white text additional information and / or code information is the target information that requires processing to make the display stand out by masking from all additional information added to the video.

[0035] The position, layout, and amount of content of the target information on the video screen that needs to be masked to make it stand out will all change dynamically depending on different videos and actual needs. For example, the position of the target information on the video screen may be one or more of the bottom left and top right of the video. In this embodiment, the target information may be one or more, and this embodiment does not impose any restrictions. Therefore, in order to reduce the influence of the mask layer on the video screen area that does not need to be displayed prominently, and to make the transition and connection of the color of the target information that needs to be displayed prominently and other video screens natural, the embodiment of the present disclosure proposes a masking process that is dynamically and adaptively adjusted, which will be specifically described as follows.

[0036] First, a mask layer area in a video frame is determined. Here, the mask layer area includes a first area that matches the target information to be prominently displayed, and a second area that transitions in color from the first area to another video screen that does not have a mask layer area. In this way, in the mask layer area in this embodiment, the parameters (e.g., height, size, shape, etc.) of the first area for prominently displaying the target information dynamically match the size of the area in which the target information exists. Therefore, the corresponding first area is determined based on factors such as the size of the area in which the target information exists. Note that in this embodiment, the target information may be one or more. Accordingly, the first area for prominently displaying the target information may also be one or more, and this embodiment does not impose any restrictions on this. In order to more clearly explain how to determine the corresponding first area based on the target information that needs to be prominently displayed by the mask layer in the video frame, a specific explanation will be given of how to determine the first area for prominently displaying the target information, taking as an example a case in which the target information is contributor information and video description information that are placed in order at the bottom of the screen of the video frame. A specific explanation will be given as follows.

[0037] In some application scenarios, the poster information and the video description information are displayed in order at the bottom of the screen of the video frame. When the video description information is below the poster information and the target information includes the poster information and the video description information, the corresponding first area can be determined based on the amount of information, layout position, etc. of the poster information and the video description information, including but not limited to the following three scenarios:

[0038] Scenario 1: As shown in FIG. 2a, the contributor information and video description information are aligned at both ends of the video frame width. In this case, the contributor information and video description information at the bottom of the video are laid out aligned to the video width, and there is no empty video screen between the video boundary. Therefore, a first height from the contributor information to the bottom of the video frame is calculated. A first region is determined based on the first height and the width of the video frame so that the first region changes dynamically with the target information. This reduces the impact on the color of other empty video screens without additional information in the video frame. The first region is as shown by the bold line in FIG. 2a.

[0039] Scenario 2: As shown in FIG. 2b, the contributor information and video description information are aligned to the left edge of the video frame width. In this case, the contributor information and video description information below the video are laid out aligned to the left boundary of the video, and there is a blank video screen without additional information between the right boundary of the video. Therefore, a second height from the contributor information to the bottom of the video frame is calculated. The first region is determined based on the second height and the end position of each line of the contributor information and video description information so that the first region changes dynamically with the target information. This reduces the influence on the color of other blank video screens without additional information in the video frame. The first region is as shown by the bold line in FIG. 2b.

[0040] Scenario 3: As shown in FIG. 2c, the contributor information and video description information are aligned to the right edge of the video frame width. In this case, the contributor information and video description information below the video are laid out aligned to the right boundary of the video, and there is a blank video screen without additional information between the left boundary of the video. Therefore, a third height from the contributor information to the bottom of the video frame is calculated. The first region is determined based on the third height and the start position of each row of the contributor information and video description information so that the first region dynamically changes with the target information. This reduces the influence on the color of other blank video screens without additional information in the video frame. The first region is as shown by the bold line in FIG. 2c.

[0041] Furthermore, in order to make the color transition and connection between the target information that needs to be highlighted and other video screens that have not been masked more natural, a second area is provided adjacent to the first area and used for the color transition and connection of the screen. This shows that the functions of the second area of ​​the mask layer area and the first area are different. The second area is a buffer transition area in which the color of the screen can be used for the color transition and connection from the first area to other areas without a mask layer, and becomes transparent from the color of the mask layer that highlights the display. In this embodiment, the first area may be one or more. Accordingly, the corresponding second area may be one or more. The first area is determined by matching based on the size of the area of ​​the target information and the area where the target information exists, and the second area is used to make the color transition and connection from the first area to the video screen of the area without the mask layer in the video frame, so the second area may be specifically determined according to the boundary of the first area and the situation of the area that can be extended and expanded outward. The second area may be determined in different manners depending on the application scenario. For example, the size of the second area to be installed adjacent to the first area may be determined based on a preset association relationship based on the width and / or height of the video and / or the area occupancy rate of the first area. This allows color transition and connection to be performed based on the second area, making the colors on the screen natural and smooth. In order to more clearly explain the method of determining the second area, an example will be given below.

[0042] Step a: determining an extension boundary line extending from a first region to another region of the video frame;

[0043] First, the expansion boundary line needs to be determined. The expansion boundary line is a boundary line that can be extended to other regions of the video frame. In some application scenarios, the first region has multiple boundaries, but not all of the boundaries can be extended to other regions of the video frame. Based on the above Figs. 2a, 2b, and 2c, further examples are given. As shown in Fig. 3a, if the first region is a rectangular region at the bottom of the video frame, and among the four boundaries, only the upper one can be extended to other regions of the video frame, the boundary line is an expansion boundary line. As shown in Fig. 3b, if the first region is a sector region at the bottom left of the video frame, and among the three boundaries, only the arc line can be extended to other regions of the video frame, the arc line boundary line is an expansion boundary line. Similar to that shown in Fig. 3b, as shown in Fig. 3c, if the first region is a sector region at the bottom right of the video frame, and among the three boundaries, only the arc line can be extended to other regions of the video frame, the arc line boundary line is an expansion boundary line.

[0044] Step b: determining a stretch size based on the other regions and the regional parameters of the first region;

[0045] Step c: determining a second region along the expansion boundary line based on the stretch size.

[0046] Further, the stretch size is determined based on the region parameters of the other region and the first region. Here, different region parameters may be selected to determine the stretch size according to the needs of the application scenario. For example, the relevant stretch size may be determined based on the region size of the other region and the region size of the first region, or the relevant stretch size may be determined based on the region shape of the other region and the region shape of the first region. Further, the second region may be determined along the expansion boundary line based on the stretch size. In order to more clearly explain the determination procedure of the second region, an example is taken as follows:

[0047] As shown in FIG. 3a, when the first region is a rectangle and the expanded boundary line is the boundary line above the rectangle, it is determined that the associated extension size is 1 / 3 of the height of the first region when the first region and the other region are rectangles based on the preset extension size and the associated relationship between the shapes of the first region and the other region. Therefore, it is determined to extend upward along the expanded boundary line based on the extension size of 1 / 3 of the height of the first region to determine the second region. Thus, the second region is a rectangle above the first region in FIG. 3a. As shown in FIG. 3b, when the expanded boundary line is a fan-shaped arc line, it is determined that the associated extension size of the area of ​​the first region and the other region shown in FIG. 3b is 1 / 6 of the radius of the fan-shaped of the first region based on the preset extension size and the associated relationship between the areas of the first region and the other region. Thus, it is determined to extend upward along the expanded boundary line based on the extension size of 1 / 6 of the height of the first region to determine the second region. Thus, when the first region is a sector at the lower left of the video frame, the second region is 1 / 4 of the circle that the first region expands outward in Fig. 3b. As shown in Fig. 3c, when the first region is a sector at the lower right of the video frame, the second region is 1 / 4 of the circle that the first region expands outward in Fig. 3c. Here, the processing procedure of the extension size is similar to the determination procedure of the extension size in Fig. 3b, and will not be further described here.

[0048] As can be seen, it is not preferable that the stretch size is too large. If the stretch size is too large, the area of ​​the second region determined based on the stretch size becomes too large, and the area in which the mask layer affects the video frame becomes too large. Also, it is not preferable that the stretch size is too small. If the stretch size is too small, the area that becomes a gradation to transparency becomes too small, and the transition becomes unnatural. Therefore, the stretch size may be determined based on the other region and the first region. This ensures that the occupancy rate of the second region in the other region is appropriate, does not excessively affect the video frame, and the ratio between the second region and the first region is appropriate, and the visual effect is harmonious. In an optional embodiment, the correspondence relationship between the other region, the first region, and the stretch size may be standardized by testing and stored in advance. Based on the other region and the first region, a search operation is performed in the storage area to obtain the stretch size.

[0049] Step 102: Obtain a target mask layer that matches the first region and the second region and has a gradation from the first region to the second region to transparency.

[0050] After determining the first and second regions, a target mask layer of a size adaptively matching the first and second regions may be determined. The first region is used to prominently display the target information, and the second region is used for color transition and connection on the screen. Therefore, the transparency of the target mask layer corresponding to the first region is generally low, the transparency of the target mask layer corresponding to the second region is generally high, and the target mask layer has a gradation from the first region to the second region to transparency. The target mask layer may be obtained in different modes according to needs. In this embodiment, no limitations are imposed, and the following is a specific description.

[0051] Based on the above embodiment, there are several ways to determine the target mask layer. For example, a target mask layer with a gradation effect from the first region to the second region to become transparent may be generated according to the sizes of the first region and the second region. Also, a target mask layer area with a size matching the first region and the second region may be obtained according to the shape of the first region and the second region joined together (for example, a mask layer shape layer matching the joined shape of the first region and the second region is selected from the mask layer shape layers of various gradation effects generated in advance by employing a masking tool, and a target mask layer area with a size matching the first region and the second region is selected from the selected mask layer shape layer). Specifically, obtaining a target mask layer that matches the first region and the second region in the above embodiment and has a gradation from the first region to the second region to become transparent may include at least the following two scenarios.

[0052] Scenario 1: Generate a target mask layer with a gradient effect from a first region to a second region to transparency according to the sizes of the first region and the second region. Specifically, it may include:

[0053] The fixed mask layer template used in the conventional linear processing has a relatively obvious sense of black division, which is poor in visibility, especially in video frames with a light background. Therefore, in this embodiment, a nonlinear curve can be used to generate a target mask layer. This nonlinear curve can make the generated target mask layer transition naturally, improving visibility. In an optional embodiment, the nonlinear curve includes a Bezier curve, and further, a gradation process is performed on the mask layer of a size matching the first region and the second region according to a preset nonlinear curve function, to obtain a target mask layer with a gradation from the first region to the second region to transparent.

[0054] Scenario 2: According to the shape of the joined first and second regions, a target mask layer region is obtained that has a size matching the first and second regions.

[0055] For example, according to the shape of the first region and the second region joined together, a mask layer shape layer that matches the joint shape of the first region and the second region may be selected from the mask layer shape layers of various gradation effects generated in advance by using a masking tool, and a target mask layer region of a size that matches the first region and the second region may be selected from the selected mask layer shape layer.

[0056] First, a mask layer shape diagram is obtained that has a gradation from the first region to the second region to be transparent, based on the joint shape between the first region and the second region.

[0057] Then, a target mask layer having a size matching the first region and the second region is cut out from the mask layer shape diagram.

[0058] In this embodiment, a mask layer shape layer with various gradation effects can be generated in advance using a masking tool. Here, in order to smooth the color transition with the mask layer area of ​​the video frame, in this embodiment, a nonlinear curve is used to perform color gradation processing, and visibility is improved by finer granularity color processing. In an optional embodiment, the nonlinear curve includes a Bezier curve. The mask layer shape layer generated by the masking tool may include multiple types of mask layer shape layers. For example, there are a radial circular mask layer shape layer with a gradation from dark to transparent from the circle center to the circular boundary, a rectangular mask layer shape layer with a gradation from dark to transparent from bottom to top or top to bottom, and a rectangular mask layer shape layer with a gradation from left to right or right to left. Furthermore, the various mask layer shape layers generated are stored. Based on the joint shape between the first region and the second region, a mask layer shape diagram with a gradation from the first region to the second region is obtained, and a target mask layer of a size matching the first region and the second region is cut out from the selected mask layer shape diagram. In order to more clearly explain the processing procedure, an example is given as follows.

[0059] When the joint shape between the first region and the second region is a sector shape, a radial circular mask layer shape layer can be obtained from the storage region, which has a gradation from dark to transparent from the circle center to the circular boundary. Here, the radial mask layer diagram includes a sector region with a gradation from the first region to the second region to transparent. As shown in FIG. 5a, in an optional embodiment, the shape and color of the radial mask layer are as in the radial mask layer diagram in FIG. 4, and the relationship between the radial mask layer and the video frame is as shown in FIG. 5a. In FIG. 5a, the target mask layer is generated by cutting out based on the parameters of the video frame. Optionally, the width of the video frame is 47% of the width of the radial mask layer, and the position of the radial mask layer is offset 15% of the width of the video frame to the right side of the screen, and the radial mask layer bisects the horizontal line and overlaps the bottom of the video frame. Thereby, the overlapping part of the radial mask layer, the first region, and the second region is set as the target mask layer.

[0060] When the joining shape between the first region and the second region is rectangular, a rectangular mask layer diagram is obtained. The shape and color of the rectangular mask layer diagram are as shown in the rectangular mask layer diagram in FIG. 4. Here, the rectangular mask layer diagram includes a rectangular region that has a gradation from the first region to the second region to transparent. Similar to the case where the joining shape is a sector shape, when the joining shape is rectangular, a target mask layer that matches the first region and the second region may be cut out from the rectangular mask layer diagram based on the relative position between the rectangular mask layer diagram and the video frame and the size relationship of the figures. In an optional embodiment, the target mask layer is as shown in FIG. 5b. In this embodiment, the rectangular mask layer diagram may be generated based on a Bezier curve.

[0061] In the above embodiment, a method for generating two target mask layers is specifically described, and the transition between the generated target mask layers is natural and the visibility is improved.

[0064] Example 1: Overlay processing is performed on the target mask layer and the mask layer area above the video frame.

[0065] Example 2: Overlay processing is performed on the target mask layer and the mask layer area below the video frame.

[0066] Example 3: A superimposition process is performed on the target mask layer and the mask layer regions above and below the video frame. In this superimposition method, the target mask layer is superimposed simultaneously on the upper and lower parts of the video frame, so that the conspicuous effect of the target mask layer can be more clearly seen.

[0067] As described above, in the video mask layer display method according to the embodiment of the present disclosure, the mask layer area determined in the video frame includes a first area that matches the target information that is prominently displayed, and a second area that transitions in color from the first area to another video screen that does not have a mask layer area. Thus, the first area makes the presentation of the target information clearer, and the second area makes the color transition between the first area and the video frame more natural. In addition, the first area is dynamically and adaptively adjusted according to the size of the target information, and the second area is also dynamically and adaptively adjusted according to the first area, so that the video frame with the target mask layer superimposed can clearly display the target information while avoiding the problem of greatly affecting the color of the original video frame.
