Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0013] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0014] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0015] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0016] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0017] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0018] It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, scope of use, usage scenarios, etc. of the personal information involved in the present disclosure should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with relevant laws and regulations.

[0019] For example, in response to receiving an active request from a user, a prompt message is sent to the user to clearly prompt the user that the operation requested to be performed will require obtaining and using the user's personal information. Thus, the user can autonomously choose whether to provide personal information to software or hardware such as an electronic device, application, server, or storage medium that performs the operation of the technical solution of the present disclosure according to the prompt message.

[0020] As an optional but non-limiting implementation, in response to receiving an active request from the user, the prompt information may be sent to the user in the form of a pop-up window, in which the prompt information may be presented in text form. In addition, the pop-up window may also carry a selection control for the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0021] It is understandable that the above notification and the process of obtaining user authorization are merely illustrative and do not constitute a limitation on the implementation of the present disclosure. Other methods that meet the relevant laws and regulations may also be applied to the implementation of the present disclosure.

[0022] At the same time, it is understandable that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and relevant provisions.

[0023] As mentioned in the background art, in the related art, the transparency of the video mask is usually set to a fixed value, which causes problems such as poor readability of visual elements in the mask.

[0024] For example, in short video applications, a bottom mask is usually set at the bottom of the video playback page to display the user's published information. However, since the transparency of the bottom mask is generally a fixed value, when the brightness of the video in the video playback page is low, the mask will further reduce the brightness of the video, making the video look darker or less vivid, which not only affects the user's viewing experience, but also reduces the readability of the published information due to the low brightness of the video, thereby affecting the user's efficiency in obtaining information from the video. In addition, when the background color of the video is similar to the color of the published information in the mask, the published information is easily submerged by the background, thereby affecting the readability of the published information.

[0025] In order to overcome the above technical problems, the transparency of the mask can be adjusted in the related technology based on fixed frame extraction and brightness evaluation. For example, for a video, a certain number of video frames can be extracted at fixed time intervals. For example, for a 40-second video, a video frame can be extracted every 4 seconds until 10 video frames are extracted. Then, the video brightness is calculated based on the 10 extracted video frames, and the video brightness is scored based on preset rules to obtain the overall brightness score of the video. Finally, the transparency of the bottom mask is adjusted based on the brightness score. For example, if the brightness score is low, the transparency of the mask can be increased to make the video look brighter; if the brightness score is high, the transparency can be reduced to prevent the mask from being too prominent.

[0026] In this way, since the transparency of the mask is determined based on the fixed frame extraction result, and the transparency of the mask is fixed during the entire video playback process, while the video content changes dynamically, this method cannot adapt to changes in video content in real time and has certain limitations. For example, when there is video content with light and dark changes in the video, the fixed transparency of the mask will cause the display brightness of the video to change dynamically, thus affecting the user's video viewing experience.

[0027] In view of this, the present disclosure provides a video mask processing method, device, medium, electronic device and program product to solve the above technical problems.

[0028] The embodiments of the present disclosure are further explained below with reference to the accompanying drawings.

[0029] Figure 1 is a flowchart of a video mask processing method according to an exemplary embodiment of the present disclosure, referring to Figure 1 , the method may include the following steps: S101: During video playback, determine a display area for displaying target content through a mask in a video frame.

[0030] In this embodiment, the target content may be text, icon, watermark, interactive control or other, which is determined according to actual conditions, and the embodiment of the present disclosure does not impose any limitation on this.

[0031] S102: Determine a target color of the display area, wherein the target color is a main color of the display area or is obtained by blending a plurality of colors whose color proportions in the display area are greater than a preset proportion.

[0032] For example, the display area of ​​the target content displayed through the mask in the video frame can be intercepted to obtain the target image, and then the number of times each color appears in the target image can be counted, and the color with the most appearances can be determined as the target color of the display area. Alternatively, the number of times each color appears in the target image can be counted, and then for each color, the corresponding color proportion can be calculated; then, according to the preset proportion threshold and the color proportion of each color, the colors that meet the conditions are screened out; finally, the screened colors are merged by weighted averaging or median mixing to obtain the target color of the display area.

[0033] It should be understood that the colors in the image are generally represented by the RGB (Red, Green, Blue) color space. Each color is composed of three components of red (R), green (G) and blue (B) in different proportions, and the value range of each component is usually 0 to 255, which results in a very large color space. If the number of occurrences of each color is directly counted, the amount of data may be too large and the processing efficiency may be low. Therefore, in order to improve the statistical efficiency, the target image can be compressed before the color statistics are performed to reduce the amount of data to be processed. At the same time, since there may be many similar or close colors in the target image, if the number of occurrences of each color is directly counted, the statistical results may be too complicated. Therefore, in order to further reduce the amount of data processing and improve the efficiency of color determination, some similar colors can be counted as the same color. For example, colors with similar RGB values ​​can be classified into one category, that is, a threshold can be set in advance, and if the RGB difference of two colors is within the threshold, they are considered to be the same color.

[0034] S103: Determine the color brightness of the target color, and determine the color difference between the target color and the display color of the target content.

[0035] It should be understood that color brightness refers to the lightness or darkness of a color, which can be measured by a simple average method (i.e. L ) or weighted average method (i.e. ) can be calculated, or it can be calculated by other methods, and the embodiments of the present disclosure do not impose any restrictions on this. In view of the fact that the L channel in the LAB color space represents brightness, it is possible to more accurately describe the brightness of the color and more accurately determine the color difference between different colors. Therefore, in a possible way, after obtaining the target color, the target color can be converted from the RGB color mode to the Lab color mode, and then the color brightness of the target color and the color difference between the target color and the display color of the target content are calculated.

[0036] Among them, the LAB color space consists of brightness (L), color channel a and color channel b. The color range included in color channel a is: dark green to pink, and the color range included in color channel b is: bright blue to yellow.

[0037] In addition, it should be understood that color difference, also known as color distance, can be obtained by calculating the Euclidean distance in the color difference space, or by a color difference calculation formula, for example, it can be obtained by the color difference calculation formula CIEDE2000 (Colordifference formula CIE Delta E 2000). Of course, it can also be calculated by other methods, and the embodiments of the present disclosure do not impose any restrictions on this.

[0038] In this step, the color brightness and color difference are determined by first determining the color brightness and then determining the color difference, or by first determining the color difference and then determining the color brightness, or by simultaneously determining the color brightness and color difference. The embodiments of the present disclosure do not impose any limitations on this.

[0039] S104: Determine the target transparency of the mask layer in the display area according to the color brightness and / or color difference.

[0040] Through the above technical solution, during the video playback, the display area of ​​the target content displayed through the mask layer can be determined, and the target color of the display area, the color brightness of the target color, and the color difference between the target color and the display color of the target content can be determined, and then the target transparency of the mask layer in the display area can be determined according to the color brightness and / or color difference. Therefore, during the video playback, the transparency of the mask layer in the display area can be dynamically adjusted in real time according to the color brightness and / or color difference corresponding to each video frame. On the one hand, the readability of the target content and / or the vividness of the video color can be increased; on the other hand, by dynamically adjusting the transparency of the mask layer, the display brightness of the video can be kept basically consistent during different playback periods of the video, thereby increasing the user's video viewing experience. In addition, since only the display area is processed, the data processing amount can be reduced, and the mask layer processing speed and processing results can be improved.

[0041] For example, Figure 2 As shown, Figure 2 (a) and Figure 2 (b) is a schematic diagram showing the comparison of the display area in the same video frame before and after processing, where: Figure 2 (a) is a schematic diagram of the display area before processing. Figure 2 (b) is a schematic diagram of a display area after being processed by the video mask processing method provided in this embodiment, according to Figure 2 (a) and Figure 2(b) It can be seen that by adjusting the transparency of the video mask through the video mask processing method provided in this embodiment, not only the vividness of the video color can be improved, but also the readability of the target content can be increased, so that users can quickly obtain information from the video content, thereby improving the user's video viewing experience.

[0042] To facilitate understanding of the content display method provided by the present disclosure, possible implementation methods in the present disclosure are described below.

[0043] In a possible manner, determining the target transparency of the mask in the display area according to the color brightness and / or color difference may include: According to the color brightness and / or color difference, the adjustment amplitude of the mask transparency in the display area is determined; according to the preset mask transparency threshold and the adjustment amplitude, the target transparency of the mask in the display area is determined, wherein the mask transparency threshold includes the minimum mask transparency and the maximum mask transparency pre-set for the display area.

[0044] In this embodiment, the minimum mask transparency and the maximum mask transparency can be determined according to actual conditions, and the embodiment of the present disclosure does not impose any restrictions on this. For example, the minimum mask transparency can be in the range of [0~1]; the maximum mask transparency can be in the range of [0~1].

[0045] In this embodiment, the minimum mask transparency and the maximum mask transparency can be fixed or dynamically changed. When the minimum mask transparency and the maximum mask transparency are dynamically changed, the minimum mask transparency and the maximum mask transparency can be flexibly adjusted according to historical browsing data, time, ambient light and / or video content importance. For example, the ambient light intensity can be obtained through a light sensor in a terminal device. When the ambient light is strong, the minimum mask transparency is set to 0.5 and the maximum mask transparency is set to 1; when the ambient light is dark, the minimum mask transparency is set to 0.2 and the maximum mask transparency is set to 0.8.

[0046] In a possible manner, the video is played in the terminal device through the target application, and the mask transparency threshold is obtained by the terminal device in the following manner: In response to the start of the target application, an acquisition request for obtaining a mask transparency threshold is generated; the acquisition request is transmitted to the server, so that after receiving the acquisition request, the server determines the mask transparency threshold based on the historical browsing data of the target application in the terminal device, and feeds back the mask transparency threshold to the terminal device.

[0047] In this embodiment, the terminal device may be a mobile terminal device, such as a mobile phone or a tablet, or a non-mobile terminal device, such as a desktop computer, etc. The target application may be a short video application, a social application, or other applications, and the embodiment of the disclosure does not impose any restrictions on this.

[0048] For example, the terminal device is a smart phone, and the target application is a short video application. Therefore, when the user opens the short video application in the smart phone, the processor in the smart phone can generate an acquisition request for obtaining the mask transparency threshold, and transmit the acquisition request to the server. After receiving the acquisition request, the server can obtain historical browsing data in the short video application from the smart phone with the authorization of the user, such as browsing time, browsing time period, and type of browsed video, and then determine the mask transparency threshold based on the historical browsing data, and feed back the mask transparency threshold to the smart phone, thereby obtaining the mask transparency threshold.

[0049] By the above method, when the target application is started, the mask transparency threshold can be obtained from the server. Compared with storing the mask transparency threshold in the target application, the mask transparency threshold can be updated without updating the program version of the target application, thereby not only simplifying the complexity of the mask transparency threshold update operation, but also improving the update speed of the mask transparency threshold. In addition, since the mask transparency threshold is determined based on the historical browsing data of the target application in the terminal device, the user's historical behavior and preference can be determined based on the historical browsing data, and then the mask transparency threshold can be dynamically adjusted according to the user's historical behavior and preference to adapt to the visual needs and usage habits of different users.

[0050] In a possible manner, determining the adjustment amplitude of the transparency of the mask in the display area according to the color brightness and / or color difference may include: When the color difference is less than a first preset color difference, or when the color brightness is greater than or equal to the first preset color brightness, the adjustment amplitude of the mask transparency in the display area is determined to be the first adjustment amplitude; when the color brightness is less than the first preset color brightness and greater than the second preset color brightness, and the color difference is greater than or equal to the first preset color difference, the adjustment amplitude of the mask transparency in the display area is determined based on the color brightness, the first preset threshold value and the second preset threshold value, wherein the first preset color brightness is greater than the second preset color brightness, and the first preset threshold value and the second preset threshold value are positive integers; when the color brightness is less than or equal to the second preset color brightness, the adjustment amplitude of the mask transparency in the display area is determined to be the second adjustment amplitude.

[0051] In this embodiment, the first preset color difference, the first preset color brightness, the second preset color brightness, the first adjustment amplitude, the second adjustment amplitude, the first preset threshold and the second preset threshold can all be determined according to actual conditions, and the embodiment of the present disclosure does not impose any restrictions on this. For example, the first preset color difference can be set to 8, the first preset color brightness can be set to 90, the second preset color brightness can be set to 80, the first adjustment amplitude can be set to 1, the second adjustment amplitude can be set to 0, the first preset threshold can be set to 90, and the second preset threshold can be set to 80.

[0052] In a possible manner, in order to enable a relatively dark video to have an obvious brightening effect of the text; for a relatively bright video, the contrast color of the mask can be retained to improve the efficiency of information transmission. The first preset color difference, the first preset color brightness, the second preset color brightness, the first adjustment amplitude, the second adjustment amplitude, the first preset threshold and the second preset threshold can be determined according to the readability of the text in videos of different brightness levels.

[0053] In this embodiment, based on the color brightness, the first preset threshold and the second preset threshold, the adjustment amplitude of the transparency of the mask in the display area can be determined by pre-constructing a linear calculation formula or a non-linear calculation formula between the color brightness, the first preset threshold and the second preset threshold, so that after obtaining the color brightness, the color brightness can be substituted into the pre-constructed calculation formula to obtain the adjustment amplitude of the transparency of the mask in the display area. It can also be that the color brightness, the first preset threshold and the second preset threshold are pre-used as the input of the model, and the adjustment amplitude of the transparency of the mask in the display area is used as the output of the model, so as to train the machine learning model based on the input and output to obtain the adjustment amplitude prediction model, so that after obtaining the color brightness, the color brightness can be substituted into the adjustment amplitude prediction model to obtain the adjustment amplitude of the transparency of the mask in the display area. Of course, it can also be obtained by other means, and this public embodiment does not impose any restrictions on this.

[0054] In a possible manner, determining the adjustment amplitude of the transparency of the mask in the display area based on the color brightness, the first preset threshold and the second preset threshold may include: Determine a first value obtained by subtracting a second preset threshold from the color brightness; determine a second value obtained by subtracting the second preset threshold from the first preset threshold, wherein the first preset threshold is greater than the second preset threshold; and determine a third value obtained by dividing the first value by the second value as an adjustment amplitude of the mask transparency in the display area.

[0055] For example, continuing to refer to the above example, if the second preset threshold is set to 80 and the first preset threshold is set to 90, the adjustment amplitude of the transparency of the mask layer in the display area can be determined by the following formula:

[0056] in, Indicates the adjustment amplitude, Indicates the color brightness.

[0057] That is to say, in a possible manner, the adjustment amplitude of the transparency of the mask in the display area can be determined by the following formula: when or hour, ,in, Indicates color difference; when hour, ; when and hour, .

[0058] As mentioned above, the first preset color difference, the first preset color brightness, the second preset color brightness, the first adjustment amplitude, the second adjustment amplitude, the first preset threshold and the second preset threshold can be determined according to the readability of the text in videos of different brightness levels. The inventors have found through a large number of experiments that when the color brightness is greater than or equal to 90, the entire video is relatively bright, which will reduce the readability of the target content in the mask layer. Therefore, the adjustment amplitude can be set to 1, so that the transparency of the mask layer can be adjusted to the maximum extent, so that the mask layer is as opaque as possible, thereby improving the readability of the target content. When the color difference between the target content and the mask display area is small, for example, when the color difference is less than 8, since the display color of the target content is close to the display color of the mask display area, the readability of the target content in the mask layer is also poor. Therefore, the adjustment amplitude can also be set to 1, so that the mask layer is as opaque as possible, thereby improving the readability of the target content. When the color brightness is less than or equal to 80, the entire video is relatively dim, and the readability of the displayed content is relatively good. Therefore, in order to reduce the amount of data processing, the adjustment amplitude can be set to 0, that is, the transparency of the mask is not adjusted. When the color brightness is between 80 and 90 and the color difference is large, in order to avoid dynamic changes in the readability of the displayed content, this embodiment determines the adjustment amplitude in a linear change manner, so that when the video brightness is close to 90, the adjustment amplitude can be larger, and when the video brightness is closer to 80, the adjustment amplitude can be smaller, so that a smooth transition can be performed, thereby improving the readability of the content and the video viewing experience.

[0059] In a possible manner, determining the target transparency of the mask layer in the display area according to a preset mask layer transparency threshold and adjustment amplitude may include: Determine a fourth value obtained by subtracting the minimum mask transparency from the maximum mask transparency; determine the product of the fourth value and the adjustment amplitude to obtain a candidate mask transparency; and determine the sum of the candidate mask transparency and the minimum mask transparency as the target transparency of the mask in the display area.

[0060] That is to say, after obtaining the adjustment amplitude, the adjustment amplitude can be substituted into the following formula to obtain the target transparency of the mask in the display area:

[0061] in, Indicates target transparency, Indicates the minimum mask transparency. Indicates the maximum transparency of the mask.

[0062] Through the above method, the target transparency can be determined according to the maximum mask transparency, the minimum mask transparency and the adjustment amplitude, so that the target transparency of the mask can be dynamically adjusted between the maximum mask transparency and the minimum mask transparency to adapt to different display requirements, thereby improving the user experience.

[0063] In a possible manner, the video mask processing method may further include: After determining the target transparency of the mask layer in the display area, the transparency of the mask layer in the display area is transitioned to the target transparency through a preset animation.

[0064] In this embodiment, the preset animation may be a UIView animation, or a Spring animation, or of course other animations, and the present disclosure embodiment does not impose any limitation on this.

[0065] For example, when the preset animation is a UIView animation, the target playback duration of the UIView animation may be preset, whereby the transparency of the mask layer may be transitioned from the current transparency to the target transparency within the target playback duration through the UIView animation.

[0066] In the above manner, the transparency of the mask layer can be smoothly transitioned through a preset animation. Compared with directly jumping from the current transparency to the target transparency, the jumping effect between different transparencies can be avoided, thereby improving the user's viewing experience of the video.

[0067] Based on the same concept, the embodiment of the present disclosure also provides a video mask processing device, such as Figure 3 As shown, the video mask processing device 300 may include: A first determination module 301 is used to determine a display area for displaying target content through a mask in a video frame during video playback; A second determination module 302 is used to determine a target color of the display area, wherein the target color is a main color of the display area or is obtained by blending multiple colors whose color proportions in the display area are greater than a preset proportion; A third determination module 303 is used to determine the color brightness of the target color and determine the color difference between the target color and the display color of the target content; The fourth determination module 304 is used to determine the target mask transparency in the display area according to the color brightness and / or color difference.

[0068] Through the above-mentioned video mask processing device 300, during the video playback process, the display area of ​​the target content displayed through the mask can be determined, and the target color of the display area, the color brightness of the target color, and the color difference between the target color and the display color of the target content can be determined, and then the target transparency of the mask in the display area can be determined according to the color brightness and / or color difference. Therefore, during the video playback process, the transparency of the mask in the display area can be dynamically adjusted in real time according to the color brightness and / or color difference corresponding to each video frame. On the one hand, the readability of the target content and / or the vividness of the video color can be increased; on the other hand, by dynamically adjusting the transparency of the mask, the display brightness of the video can be kept basically consistent during different playback periods of the video, thereby increasing the user's video viewing experience. In addition, since only the display area is processed, the data processing amount can be reduced, and the mask processing speed and processing results can be improved.

[0069] In a possible manner, the fourth determining module 304 may include: A first determination submodule, used to determine the adjustment amplitude of the transparency of the mask layer in the display area according to the color brightness and / or color difference; The second determination submodule is used to determine the target transparency of the mask in the display area according to a preset mask transparency threshold and an adjustment amplitude, wherein the mask transparency threshold includes a minimum mask transparency and a maximum mask transparency pre-set for the display area.
