Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative labor shall fall within the protection scope of the present disclosure. 【0014】 Hereinafter, the application scenarios of the embodiments of the present disclosure will be described. 【0015】 Figure 1 is an application scene diagram of an image preview method provided by an embodiment of the present disclosure. The image preview method provided by an embodiment of the present disclosure can be applied to a scene in which media data is uploaded to a content creation application based on a terminal device. More specifically, it can be applied to an application scene in which output media data is loaded, and the output media data is media data to be edited and uploaded to a content creation application. As shown in Figure 1, the method provided by an embodiment of the present disclosure can be applied to terminal devices such as smartphones. Exemplaryly, a content creation application refers to an application platform in which users can upload their own media data such as images, videos, and text. More specifically, examples include short video applications and video web applications. At the same time, other applications that have the function of allowing users to upload media data also belong to the category of content creation applications, such as social applications and news applications in which individual users can upload media data. Content creation applications include service terminals and client terminals. The client terminal operates on the terminal device side, and the user operates the terminal device to load output media data, edit this output media data, upload it to the service terminal, and complete the upload of user-created content. Other terminal devices can view the user's self-created output media data, such as videos and images, through the client terminal running the content creation application. 【0016】 In conventional technology, a trigger control is provided on the client terminal of a content creation application to upload media data corresponding to the user's created content. When the user clicks this trigger control, the client terminal displays the corresponding upload process page and guides the user to upload the media data. Figure 2 is a flowchart of media data upload in conventional technology. As shown in Figure 2, exemplarily, after the user clicks the "Upload My Work" trigger control on the client terminal, two controls, "Take Video / Photo" and "Load Video / Photo," are displayed on a newly popped-up page to guide the user to the next action. After the user clicks "Take Video / Photo," the client terminal... Camera preview page The application is launched to take a picture or video based on the user's shooting input, and output media data is generated. When the user clicks "Load Video / Photo," the client terminal launches the media database page, displays the videos and / or photos stored in the local media database or cloud media database on the terminal device, and retrieves the output media data based on the user's point selection operation. 【0017】 However, in actual application processes, in application scenarios where users create content, the process by which users create content is subjective and complex, while on the other hand, users Camera preview page In the process of taking a photograph, the user needs to observe whether the visual effect of the image displayed in the viewfinder meets the requirements, whether there is sufficient light, whether there are any obstructions, etc., and then decide whether to take the photograph. On the other hand, since there is not just one set of media data stored in the media database, the user needs to observe the content in the media database, select it, and load it. In other words, the user needs to make specific observations and then decide whether to take the photograph. Camera preview pageIt is necessary to decide whether to launch the application and acquire media data using "Real-time shooting," or to launch the media database page and acquire media data by "Loading existing media data." In conventional methods, Camera preview page You can only launch either the camera view effect or the media database page, and you cannot preview both the camera view effect and the contents of the media database simultaneously. Camera preview page Furthermore, repeatedly switching between and launching media database pages, and only being able to preview the camera's view effects and the contents of the media database, increased the time required to acquire output media data, resulting in a problem that affected the user's creative efficiency. An embodiment of this disclosure provides a method for previewing images to solve the above problem. 【0018】 Figure 3 is a flowchart 1 of a method for previewing an image provided by an embodiment of the present disclosure. The method of this embodiment can be applied to a terminal device, and this method for previewing an image includes the following: 【0019】 Step S101: In response to the camera activation command, Camera preview page Start it up, Camera preview page It includes the first interface component. 【0020】 Exemplary, the entity executing the method of this embodiment is a terminal device, more specifically, a smartphone, and a client terminal of a content creation application (hereinafter referred to as the client terminal) is running within the terminal device. The client terminal is configured with a camera control to trigger a camera activation command. After the user operates the terminal device and triggers this camera control, a corresponding camera activation command is generated, and then, in response to this camera activation command, within the client terminal... Camera preview page Start it. Figure 4 is provided by an embodiment of the present disclosure. Camera preview page This is a schematic diagram. As shown in Figure 4, exemplarily, Camera preview page Inside, Camera preview page It includes a camera viewfinder located in the center and a shooting trigger control located below the camera viewfinder, the shooting trigger control being used to control when the terminal device captures video or images. Camera preview page The camera viewfinder and shooting trigger control inside are based on prior art. Camera preview page This is a general functional unit within the system, and its principle will not be explained here. 【0021】 moreover, Camera preview page A first interface component is also located at the first target location, for example, to the right of the shooting trigger control in Figure 4. This first interface component provides an interaction entry point to the media database for displaying media data in the media database page in the form of a preview image. Here, the first interface component can be located at other target locations in addition to the location shown in Figure 4, and is not limited here; it can be configured as needed. Furthermore, the first interface component may consist of one or more components, and if the first interface component consists of multiple components, they may be placed adjacent to each other to facilitate user observation, and the specific locations are not limited and are not described here. 【0022】 Step S102: Based on the first interface component, at least two preview images are displayed within a first period, and the preview images are generated based on media data in the media database. 【0023】 For example, Camera preview pageThe application is launched, and a preview image is dynamically displayed via a first interface component. Here, the dynamic display of the preview image in the first interface component means that, within a first period, the preview image is displayed in such a way that it switches between at least two frames. This preview image is generated based on media data in a media database, for example, after identifying the target media data in the media database, and after sampling the target media data in the media database, the generated thumbnail is used as the preview image. Here, the target media data may be determined randomly or based on a certain rule. 【0024】 Furthermore, media data includes video and pictures, and if the media data is video, at least two video frames, for example, two adjacent keyframes, can be selected and extracted from the video and displayed in the first interface component as corresponding preview images after processing. Figure 5 is a schematic diagram of dynamically displaying preview images in the first interface component provided by an embodiment of this disclosure. As shown in Figure 5, Camera preview page The application is launched, and if user permission is obtained, the terminal device reads media data from the media database. Here, this media database may be a local media database or a cloud media database. At least two target media data, for example, three photos (photo A, photo B, and photo C in the diagram), are selected and retrieved from it, and then, within a first period, for example, within 2 seconds, these three photos are displayed in a switching manner within the first interface component, i.e., photo A is displayed at 0 seconds, photo B at 1 second, and photo C at 2 seconds. This allows the user to Camera preview page While looking at the preview images of three photos in the media database, 2It can be observed within seconds. Here, exemplarily, the first period is determined by the number of preview images, or the number of preview images is determined by a predetermined first period. 【0025】 Subsequently, the user can optionally decide, based on the preview image observed within the first page component, whether to load media data from the media database page corresponding to the preview image as output media data, or to capture it in real time directly through the camera viewfinder, thereby directly generating and loading the output media data. This enables a simple and quick loading of output media data, followed by the step of editing and uploading this output media data. 【0026】 In this embodiment, in response to a camera activation command, Camera preview page Start it up, Camera preview page It includes a first interface component, and based on the first interface component, displays at least two frames of preview images within a first period, and the preview images are generated based on media data in a media database. Camera preview page Because we have installed a first interface component that can dynamically display preview images, Camera preview page This enables camera views while simultaneously dynamically displaying content from the media database, thereby allowing the user to Camera preview page By observing this, it is possible to simultaneously preview the results of capturing media data in real time and the results of loading existing media data. Furthermore, the user Camera preview page This eliminates the need to launch separate media database pages and perform attempts and searches in each, supporting quick decision-making, simplifying operation steps, improving interaction efficiency, and ultimately increasing the speed of generating output media data for uploading to content creation applications. 【0027】 In addition to the embodiment shown in Figure 3, in one possible embodiment, Camera preview page The method provided by this embodiment further includes a second interface component for displaying a target visual effect added to a preview image, and the method provided by this embodiment further includes generating an effect image corresponding to the preview image based on the target visual effect displayed by the second interface component. 【0028】 Figure 6 shows other embodiments provided by the embodiments of this disclosure. Camera preview page This is a schematic diagram. As shown in Figure 6, Camera preview page A second interface component is provided at the second target position for displaying target visual effects added to the preview image, more specifically, such as a skin-beautifying effect or a sticker effect. In one possible embodiment, the second interface component changes the displayed target visual effect in response to user commands. For example, after the user clicks on this second interface component, several alternative visual effects are displayed in a pop-up window, and then, based on the user's selection of an alternative visual effect, one of them is designated as the target visual effect. 【0029】 Furthermore, based on the target visual effect displayed by the second interface component, the terminal device renders a preview image corresponding to the first interface component based on this target visual effect, thereby generating an image with this target visual effect, i.e., an effect image. Figure 7 is a schematic diagram for generating an effect image provided by an embodiment of the present disclosure. As shown in Figure 7, exemplary, if the target visual effect displayed by the second interface component is to add a seal effect of a virtual ornament (e.g., a crown as shown in the figure) to the user's avatar, and the preview image corresponding to the first interface component, i.e., the preview image generated from target media data in the media database, is a photograph containing the user's avatar, then after rendering the preview image based on the target visual effect, the generated effect image is a photograph containing the user's avatar with the virtual ornament. 【0030】 Accordingly, based on the above embodiment, a specific method of carrying out step S102 includes, based on the first interface component, displaying at least two preview images within a first period, each corresponding to an effect image. 【0031】 In this embodiment, Camera preview page After installing a first interface component, a second interface component is added to display the visual effects of the preview image. The second interface component displays and installs the target visual effects, allowing the first interface component to display a preview image with the corresponding visual effects added, thereby enabling the user to... Camera preview page By observing this, the effects after adding visual effects to media data in the media database can be further observed, allowing users to decide whether to use the media data in the media database page to generate the final output media data and then perform subsequent steps such as editing and uploading. This further reduces the number of steps required for user interaction, improves interaction efficiency, and shortens the time it takes to generate output media data. 【0032】 Figure 8 is a flowchart 2 of a method for previewing an image provided by an embodiment of the present disclosure. This embodiment adds the steps of determining the target media data in the media database page and generating the output media data to the embodiment shown in Figure 3, and the method for previewing this image includes the following: 【0033】 Step S201: Display the front page, retrieve the page information corresponding to the front page, the page information characterizes the page theme corresponding to the front page, and the front page includes a third interface component for generating user-created media corresponding to the page theme. 【0034】 Step S202: In response to the first trigger operation on the third interface component, a camera activation command containing page information is generated. 【0035】 For example, the front page is Camera preview page This is the page that triggers the action, and a third interface component is installed on the front page. For example, in the embodiment shown in Figure 2, the trigger control installed on the client terminal is named "Upload my work," and after the user clicks this trigger control, a camera activation command is generated, eliminating the need to display a page containing two controls, "Shoot video / photo" and "Load video / photo," in the embodiment shown in Figure 2. Camera preview page This is activated directly, thereby simplifying the operation flow. For specific implementations, please refer to the descriptions in the corresponding embodiments in Figures 2 and 4; further explanation is not provided here. 【0036】 Furthermore, the front page contains corresponding page information, and the terminal device can obtain the page information corresponding to the front page through the client terminal program. Here, exemplary, different front pages may correspond to different page information, and the page information characterizes the page theme corresponding to the front page. For example, front page #1 is the automotive board discussion forum in the application, the corresponding page theme is "automotive theme", and the corresponding page information for front page #1 is info_1; front page #2 is the travel board discussion forum in the application, the corresponding page theme is "travel theme", and the page information corresponding to front page #2 is info_2. Exemplary, the page information has a fixed mapping relationship with its characterized page theme, and this mapping relationship may be pre-configured; therefore, the page information may be an abstract identifier as in the above example. Furthermore, this page information can be determined by the access address of the front page. In response to the first trigger operation on the third interface component, a corresponding camera start command is generated so that the page information of this front page can be included in the camera start command based on the page information corresponding to this front page. 【0037】 Step S203: In response to the camera activation command, Camera preview page Start it up, Camera preview page It contains a first interface component and a second interface component. 【0038】 Step S204: Based on the page information during the camera activation command, target scene information is generated, and the target scene information characterizes the target content category of the media data. 【0039】 Step S205: Based on the target scene information, determine the target media data, and based on the target media data, generate at least two preview images. 【0040】 For example, after responding to the camera activation command, Camera preview page Call the corresponding startup method, Camera preview page Initialization is performed to load the data, and during the initialization phase, Camera preview page The first and second interface components within the system determine and load the data corresponding to them after the initialization phase is complete, without loading any data themselves. This allows the system to display the content corresponding to the first and second interface components. 【0041】 Here, as an example, the camera activation command includes page information that characterizes the page theme corresponding to the front page. Based on this page information and a pre-configured mapping relationship, the corresponding target scene information is obtained, and the target scene information characterizes the target content category of the media data. Content categories include, for example, vehicles, houses, landscapes, and portraits. The mapping relationship between page information and scene information is as follows: for example, if the page theme of the front page characterized by the page information is "automobile theme," the mapped target content categories are "vehicles" and "roads." If the page theme of the front page characterized by the page information is "travel theme," the mapped target content categories are "landscapes" and "portraits." Here, the scene information may also be characterized based on an abstract identifier, which can be specifically set as needed. The content categories of media data characterized by page information allow for the classification of media data based on the identification of media data. For example, videos and photographs related to "people" and "landscapes" in media data can be identified. Therefore, based on the target content category characterized by the target page information, the corresponding media data belonging to that target content category, i.e., target media data, can be obtained. Furthermore, at least two preview images can be obtained based on the target media data. A specific implementation is shown in the embodiment in Figure 3, but will not be explained further here. 【0042】 Step S206: Obtain the target visual effect based on the target scene information. 【0043】 Step S207: Display the target visual effect added to the preview image based on the second interface component. 【0044】 For example, based on target scene information, it is possible to determine a matching visual effect, i.e., a target visual effect. For instance, if the target content category corresponding to the target scene information is "landscape," visual effect A is used to add a "halo" effect. If the target content category corresponding to the target scene information is "people," visual effect B is used to add a "skin smoothing" effect. In other words, the matching target visual effect can be determined by different target scene information and a pre-defined mapping relationship. The implementation of specific mapping relationships can be set based on specific needs, and will not be explained further here. 【0045】 Furthermore, after determining the target visual effect, an identifier corresponding to that target visual effect, such as an effect icon or effect text, is displayed within a second interface component for displaying the visual effect. This enables the display and setting of the target visual effect, facilitates automatic recommendation of visual effects that match the page theme, reduces user interaction, and improves interaction efficiency. 【0046】 Step S208: Generate an effect image corresponding to the preview image based on the target visual effect displayed by the second interface component. 【0047】 Step S209: Based on the first interface component, within a first period, at least two preview images each display the corresponding effect image. 【0048】 Furthermore, after determining the target visual effect and preview image, rendering is performed based on the target visual effect preview image to generate a preview image with the visual effect, i.e., an effect image. Here, based on the above steps, the target visual effect and preview image are determined based on the target scene information of the same group, so the target visual effect and preview image themeIt can guarantee consistency at the scene level, make the generated effect images more rational, and be more similar to the results manually set and selected by experienced users, making it more user-friendly for inexperienced users. When users create content using existing media data, it can improve the quality and efficiency of the produced works. 【0049】 Furthermore, as an option, the following may be included after step S209: 【0050】 Step S210: In response to a second trigger operation on the first interface component, output media data is generated, where the second trigger operation directs a target preview image within the first interface component, and the output media data is generated based on the target preview image or target media data corresponding to the target preview image. 【0051】 Step S211: Output media data Camera preview page Display it on the front page. 【0052】 For example, since the preview image within the first interface component changes dynamically, when the terminal device detects a second trigger action on the first interface component at a first time, such as a click on the first interface component, the preview image displayed within the first interface component at that first time is the target preview image corresponding to the second trigger action. Subsequently, target media data corresponding to that target preview image, such as a video or photograph, is acquired, and after processing steps such as compression, resizing, and adding visual effects to the target media data, output media data is generated, or this target media data is used directly as output media data. After that, the client terminal running on the terminal device returns to the front page, displays the output media data on this front page, and completes the loading of the output media data. Subsequently, the output media data can be further edited and uploaded according to specific needs, but this will not be explained further here. 【0053】 Figure 9 is a schematic diagram of the process for loading output media data provided by an embodiment of the present disclosure. As shown in Figure 9, exemplarily, after clicking the “Load Image” button (third interface component) on the front page, Camera preview page Enter, Camera preview pageWithin this, the first interface component dynamically displays preview images of multiple frames. For example, at the first time, it displays preview image P1 within the first interface component; at the second time, it displays preview image P2 within the first interface component; and at the third time, it displays preview image P3 within the first interface component. At the third time, the terminal device detects a third trigger action on the first interface component, such as a user click. The terminal device then automatically acquires target media data data_1 corresponding to this preview image P1, and visually renders this target media data data_1 to generate media data with visual rendering effects, i.e., output media data. This output media data is then loaded and displayed on the front page, and optionally, the text "Loaded" is simultaneously displayed in the third interface component. 【0054】 In the steps of this embodiment, the preview image displayed in the first interface component is not manually selected by the user but is dynamically determined based on scene information. Furthermore, if visual effects are added, it may be difficult or impossible for the user to accurately find the corresponding target media data through the media database page simply by looking at the preview image. Additionally, the process of loading output media data based on the target media data takes extra time, reducing the efficiency of loading the output media data. In the steps of this embodiment, the target preview image is determined directly and the corresponding output media data is loaded onto the front page by responding to a second trigger action on the first interface component. By allowing the user to observe the preview image displayed in the first interface component and combining it with the second trigger action, the process of loading output media data can be completed, eliminating the need to launch the media database page and manually search for and select the target media data. This improves the efficiency of loading output media data and reduces time loss. 【0055】 In this embodiment, the implementation of step S203 is the same as the implementation of step S101 in the embodiment shown in Figure 3 of this disclosure. Specifically, you can refer to the explanation of the correspondence in the embodiment shown in Figure 3, and it will not be explained in general terms here. 【0056】 Figure 10 is a block diagram of an image previewing apparatus provided by the embodiments of this disclosure, corresponding to the method of previewing images in the embodiments described above.
