[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0035] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0036] The following explains the application scenarios of the embodiments of the present disclosure:

[0037] Figure 1 is an application scenario diagram of the special effect template generation method provided by the embodiment of the present disclosure. The special effect template generation method provided by the embodiment of the present disclosure can be applied to an application with an image special effect template generation function (hereinafter referred to as a special effect editing application). More specifically, it can be applied to the application scenario of designing and making special effect templates. The execution subject of this embodiment can be a terminal device that runs the above-mentioned application with the special effect template generation function, or a server that runs the service end corresponding to the above-mentioned application, or other electronic devices that perform similar functions. Referring to Figure 1, taking the terminal device as an example, the terminal device is, for example, a smart phone. The user operates the terminal device to run the special effect editing application, and uses the special effect editing application to design and generate a personalized special effect template (such as the special effect template #1 shown in the figure). Afterwards, the personalized special effect template generated by the special effect editing application can be further uploaded to the special effect platform server and published on the special effect platform. Afterwards, when other image processing applications need to call the special effect template of the special effect platform, they can use the published personalized special effect template to add image special effects to the image. In another possible application scenario, the personalized special effects template generated by the special effects editing application can also be saved locally on the terminal device. Afterwards, the image processing application is run through the terminal to load the personalized special effects template to achieve the purpose of adding personalized image special effects to the image to be processed.

[0038] Special effects templates used to achieve image deformation effects are typically designed by software developers and fixed within image processing tools for user use. Consequently, the style and shape of these special effects templates are fixed, resulting in the same visual effects for all special effects images generated using the template, lacking differentiation and personalization. Since users cannot customize templates based on their own interests and needs, special effects templates suffer from a monotonous style and lack of customization.

[0039] The embodiments of the present disclosure provide a method for generating a special effect template to solve the above problems.

[0040] Referring to FIG2 , FIG2 is a flow chart of a method for generating a special effect template according to an embodiment of the present disclosure. The method of this embodiment can be applied in a terminal device, and the method for generating a special effect template includes:

[0041] Step S101: running a first editing interface, wherein a template image and a liquefaction mark located in the template image are displayed in the first editing interface.

[0042] Step S102 : in response to a first operation on the liquefied mark, causing a first deformation of the mark outline of the liquefied mark.

[0043] Exemplarily, referring to the application scenario diagram shown in FIG1 , the first editing interface is an interactive interface for generating personalized special effects templates in a special effects editing application. In the first editing interface, at least a sample image and a liquefaction mark located in the sample image are displayed, wherein the sample image can be understood as a standard image used to express a deformation effect, more specifically, for example, a preset face image, and by deforming (liquefying) the sample image, the effect of the subsequently generated first liquefaction special effect is displayed, so that the user can preview the visual effect of the special effects template in real time and make corresponding adjustments. The liquefaction mark is a graphic mark used to receive user operations for interaction, more specifically, for example, it can be a circle, a square, etc. The location of the liquefaction mark is the location where the deformation special effect is generated in the image.

[0044] Furthermore, after the template image and the liquefied logo are displayed in the first editing interface, the terminal device receives the first operation input by the user for the liquefied logo, adjusts the logo outline of the liquefied logo, and causes the logo outline to undergo a first deformation, wherein the first deformation may refer to a change in the length and width ratio of the liquefied logo, or the overall expansion or contraction of the logo outline of the liquefied logo. Figure 3 is a schematic diagram of a first editing interface provided by an embodiment of the present disclosure. Referring to Figure 3, the first editing interface includes a template image, the sample image is a face picture; and a liquefied logo located above the template image, the outline shape of the liquefied logo being an ellipse. In one possible implementation, the initial position of the liquefied logo is located at the center of the template image. Thereafter, in response to the user's movement operation on the liquefied logo, the liquefied logo can be moved to other positions, such as the P1 point position shown in the figure. Furthermore, in response to a first operation on the liquefied marker, such as a drag operation on the control point of the liquefied marker, the marker outline of the liquefied marker is deformed. For example, as shown in the figure, when the first operation is a horizontal drag, the length of the liquefied marker changes from x1 in the initial state to x2, that is, a horizontal deformation of x2-x1 occurs; similarly, when the first operation is a vertical drag (not shown in the figure), the width of the liquefied marker changes from y1 in the initial state to y2, that is, a vertical deformation of y2-y1 occurs. The first deformation can be a vector representing the above deformation, more specifically, for example, a vector including the difference between x2 and x1, and the difference between y2 and y1; or, a set including lengths x1, x2 and widths y1, y2; or, a set of contour points describing the marker outline before and after deformation. The specific implementation form of the first deformation is not limited here.

[0045] In one possible implementation, the liquefaction marker includes at least one first control point and at least one second control point, the first control point is used to adjust the lateral deformation of the liquefaction marker; the second control point is used to adjust the longitudinal deformation of the liquefaction marker. Further, optionally, the liquefaction marker includes at least one third control point, and the third control point is used to adjust the overall scaling ratio of the liquefaction marker.

[0046] Exemplarily, the first operation includes a first sub-operation, a second sub-operation, and a third sub-operation. As shown in FIG4 , a specific implementation of step S102 includes:

[0047] Step S1021 : In response to the first sub-operation on the first control point, the outline of the liquefied logo is deformed horizontally.

[0048] Step S1022: In response to the second sub-operation on the second control point, the outline of the liquefied logo is deformed longitudinally.

[0049] Step S1023: In response to the third sub-operation on the third control point, the outline of the liquefied mark is expanded or reduced as a whole.

[0050] FIG5 is a schematic diagram of adjusting the outline of a logo provided by an embodiment of the present disclosure. As shown in FIG5 , the liquefied logo is an elliptical interactive logo, and the liquefied logo has two first control points P1 and P2, two second control points P3 and P4, and four third control points P5 to P8. When the terminal device receives the first sub-operation for the first control points P1 and P2, the logo outline of the liquefied logo undergoes a horizontal deformation, that is, the major axis of the ellipse of the liquefied logo changes from x1 to x2, where x1 and x2 are the distances of the first control points P1 and P2 before and after responding to the first sub-operation, respectively. Similarly, when the terminal device receives the second sub-operation for the second control points P3 and P4, the logo outline of the liquefied logo undergoes a longitudinal deformation, that is, the minor axis of the ellipse of the liquefied logo changes from y1 to y2, where y1 and y2 are the distances of the second control points P3 and P4 before and after responding to the first sub-operation, respectively. Furthermore, when the terminal device receives the third sub-operation for any of the third control points P5, P6, P7, and P8, the overall outline of the liquefied marker is expanded or reduced, that is, under the premise that the ratio of the major axis and minor axis of the ellipse of the liquefied marker remains unchanged, the major axis and minor axis of the ellipse are expanded or reduced synchronously. For example, as shown in the figure, the major axis of the ellipse of the liquefied marker is changed from x1 to 2 times x1, and the minor axis of the ellipse is changed from y1 to 2 times y1.

[0051] It should be noted that the above-mentioned first operation on the first control point, the second control point and the third control point can be individually targeted at any one or more of the first control point, the second control point and the third control point, and there is no restriction on the order of operating the first control point, the second control point and the third control point, nor is there any restriction on the number of times the first control point, the second control point and the third control point are operated. That is, the first operation input by the user can adjust any one of the first control point, the second control point and the third control point multiple times and without order restrictions to achieve the purpose of making the logo outline of the liquefied logo produce a specific first deformation, thereby achieving the purpose of personalized editing by the user.

[0052] Furthermore, in one possible implementation, after the terminal device receives a setting operation input by the user, the first function parameter component in the first editing interface can be set to an on state, i.e., another liquefaction icon, i.e., a mirrored liquefaction icon, is symmetrically displayed in the first editing interface. The mirrored liquefaction icon is used to generate a second liquefaction effect that is symmetrical to the first liquefaction effect. Figure 6 is a schematic diagram of a mirror liquefaction marker provided by an embodiment of the present disclosure. As shown in Figure 6, a first function parameter component is provided in the first editing interface, and the first function parameter component is in the "Off" state by default; after the terminal device receives the setting operation for the first function parameter component input by the user, the first function parameter component is set to the "On" state, and then the mirror liquefaction marker is displayed in the first editing interface. The mirror liquefaction marker and the liquefaction marker are symmetrical based on the central axis of the template image. After the above-mentioned first operation on the liquefaction marker causes the liquefaction marker to produce a first deformation, the mirror liquefaction marker will synchronously produce the same first deformation, and in the subsequent steps, a second liquefaction effect with the same liquefaction effect and symmetrical position is generated. The specific implementation method is the same as the implementation method of the liquefaction marker producing the first liquefaction effect, which will not be repeated here.

[0053] In this embodiment, by symmetrically displaying the mirrored liquefaction mark in the first editing interface, the purpose of synchronously and conveniently adding a second liquefaction effect symmetrical to the first liquefaction effect can be achieved without the need to separately configure the second liquefaction effect, thereby ensuring the consistency and symmetry of the second liquefaction effect symmetrical to the first liquefaction effect, thereby improving the display effect of the generated target special effects template.

[0054] Step S103: In response to the first deformation of the marker outline, generating a first liquefaction effect in a target area of ​​the template image; wherein the target area is an image area in the template image covered by the marker outline of the liquefied marker.

[0055] Exemplarily, the first liquefaction effect is used to cause the image elements in the target area to produce a second deformation, and the deformation amount of the second deformation corresponds to the deformation amount of the first deformation. After the logo outline of the liquefaction logo produces the first deformation, the terminal device generates a corresponding liquefaction effect on the template image according to the deformation amount of the first deformation, that is, the first liquefaction effect, and the first liquefaction effect is used to cause the image elements in the target area to produce a second deformation corresponding to the deformation amount of the first deformation. Specifically, for example, the template image is a face image, and the first liquefaction effect is used to enlarge the "eyes" covered by the liquefaction logo in the face image, that is, to produce a second deformation. The second deformation is determined in direct proportion to the first deformation, that is, the larger the deformation amount of the first deformation, the larger the deformation amount of the second deformation, and conversely, the smaller the deformation amount of the first deformation, the smaller the deformation amount of the second deformation.

[0056] Furthermore, the mapping relationship between the first deformation and the second deformation can be determined based on a preset deformation function. In a possible implementation, as shown in FIG7 , the specific implementation of step S103 includes:

[0057] Step S1031: Obtain the target deformation type.

[0058] Step S1032: Obtain a corresponding deformation function according to the target deformation type.

[0059] Step S1033: Based on the deformation variable parameter representing the deformation variable of the first deformation, a deformation function is called to obtain a corresponding pixel transformation matrix, where the pixel transformation matrix is ​​used to cause the image elements in the corresponding image area to generate a second deformation.

[0060] Step S1034: generating a first liquefaction effect in the target area of ​​the template image according to the pixel transformation matrix.

[0061] Exemplarily, the target deformation type is the deformation type of the second deformation, including, for example, scaling, expansion, wrinkling, waving, clockwise twisting, counterclockwise twisting, and so on. The target deformation type can be determined by user input, and the specific implementation of obtaining the target deformation type is not detailed here. Subsequently, a corresponding deformation function is obtained based on the target deformation type. The deformation function is used to characterize the pattern of pixel changes in the image and adjusts the pixel values ​​of the pixels in the image to achieve the visual effect of image deformation. Different target deformation types correspond to different deformation functions. For example, the "wrinkle" type corresponds to the deformation function fun_1(), and the "clockwise twist" type corresponds to the deformation function fun_2(). Furthermore, the deformation function uses at least the deformation variable parameters corresponding to the first deformation as input parameters, so that the deformation variable corresponding to the pixel transformation matrix output by the deformation function is related to the first deformation. The deformation variable parameters are a set of parameters generated based on the first deformation and having a specific data format, which are compatible with the deformation function. Exemplarily, the deformation variable parameters include at least one of the following: a horizontal deformation variable, a vertical deformation variable, and an overall scaling ratio. Furthermore, after converting the first deformation into deformation variable parameters, the deformation variable parameters are input into a deformation function, causing the deformation function to generate a pixel change matrix associated with the deformation variable of the first deformation. This pixel change matrix represents the mapping relationship between the initial image of the target area of ​​the template image and the image resulting in the second deformation. Specifically, this pixel change matrix can be used to induce the second deformation in the image within the target area, thereby forming the first liquefaction effect.

[0062] Figure 8 is a schematic diagram of a process for generating a first liquefaction special effect provided by an embodiment of the present disclosure. The above process is explained below in conjunction with Figure 8. Referring to Figure 8, after obtaining the target deformation type based on user instructions, the deformation function Func_1 (shown as Func_1() in the figure) corresponding to the target deformation type is obtained. Then, the deformation variable parameter para_1 (shown as para_1 in the figure) corresponding to the first deformation is obtained. At least the deformation variable parameter para_1 is used as the input parameter of the Func_1 function. The Func_1 function is called to obtain the corresponding pixel change matrix Mat_1. The pixel change matrix Mat_1 is used to characterize the style of the second deformation generated in the target area. Then, the pixel points in the target area of ​​the template image are processed based on the pixel change matrix Mat_1 to generate image elements with the second deformation, thereby generating the first liquefaction special effect.

[0063] Furthermore, optionally, the input parameters of the deformation function also include an adjustment parameter, which is used to characterize the intensity of the second deformation generated by the deformation function. Specifically, based on the deformation variable parameter that characterizes the deformation variable of the first deformation, the deformation function is invoked to obtain a corresponding pixel transformation matrix, where the pixel transformation matrix is ​​used to cause the second deformation of image elements within the corresponding image region. This includes obtaining the pixel transformation matrix based on the deformation variable parameter and the adjustment parameter.

[0064] Among them, when the deformation function is different, the meaning represented by the adjustment parameter is different. For example, when the deformation function is a "wrinkle" type corresponding to the deformation function fun_1(), its corresponding adjustment parameter represents the number of "wrinkles"; for another example, when the deformation function is a "clockwise selection" type corresponding to the deformation function fun_2(), its corresponding adjustment parameter represents the angle of "rotation". More specifically, the adjustment parameter can be an integer value with a fixed value range. For example, the value range of the adjustment parameter is [0,100], where 0 indicates that the intensity of the second deformation is the smallest, and 100 indicates that the intensity of the second deformation is the largest. Figure 9 is a schematic diagram of a process for setting adjustment parameters provided by an embodiment of the present disclosure. As shown in Figure 9, a slider for setting adjustment parameters is provided in the first editing interface. When the sliding range of the slider on the slider is 0 to 100, the target deformation type corresponding to the deformation function is "wave deformation". When the slider is at 15, the corresponding second deformation intensity is the first intensity (shown as Deform_1 in the figure); when the slider is at 60, the corresponding second deformation intensity is the second intensity (shown as Deform_2 in the figure). As shown in the figure, when the slider is at 60, the intensity of the second deformation in the image is greater, that is, the generated first liquefaction effect causes a greater degree of deformation in the image.

[0065] For example, the adjustment parameter component within the first editing interface can be triggered by the user to obtain the adjustment parameter. In this embodiment, the corresponding pixel change matrix is ​​determined by combining the deformation parameter and the adjustment parameter, enabling more precise adjustments to the second deformation style, thereby increasing the design flexibility and personalization of the target special effect template.

[0066] Step S104: Generate a target special effect template based on the first liquefaction special effect.

[0067] Exemplarily, the first liquefaction special effect can be represented based on the above-mentioned pixel change matrix and the set of coordinates of the corresponding target area. After obtaining the above-mentioned first liquefaction special effect, it is equivalent to obtaining a special effect style generated based on the user's personalized needs. After that, the pixel change matrix and the coordinates of the corresponding target area are encapsulated using the template generation component to generate the corresponding target special effect template. When the target special effect template is subsequently used, the relevant template information of the target area and the pixel change matrix described in the target special effect template is used to process the pixel points in the image area corresponding to the target area in the image to be processed based on the pixel change matrix, so that the image special effect identical to the first liquefaction effect appears in the image to be processed. The use process of the special effect template will not be repeated here.

[0068] In this embodiment, by running a first editing interface, a template image and a liquefaction marker located within the template image are displayed within the first editing interface; in response to a first operation on the liquefaction marker, a first deformation is generated in the marker outline of the liquefaction marker; in response to the first deformation of the marker outline, a first liquefaction effect is generated in a target area of ​​the template image; wherein the target area is the image area within the template image that is covered by the marker outline of the liquefaction marker, and the first liquefaction effect is used to cause the image elements within the target area to produce a second deformation, the deformation amount of the second deformation corresponding to the deformation amount of the first deformation; based on the first liquefaction effect, a target special effects template is generated. By controlling the liquefaction marker within the first editing interface, a first deformation is generated on the sample image, thereby mapping it to the first liquefaction effect, and generating a target special effects template corresponding to the first liquefaction effect, thereby realizing personalized special effects template generation based on user operations, and solving problems such as the single style of special effects templates and the inability to personalize and adjust them.

[0069] Referring to Figure 10, Figure 10 is a second flow chart of the special effect template generation method provided by the embodiment of the present disclosure. Based on the embodiment shown in Figure 2, this embodiment further refines step S101 and adds steps such as generating a superimposed special effect template. The special effect template generation method includes:

[0070] Step S201: displaying a special effect editing panel, wherein the special effect editing panel is provided with at least one template component and an editing component, wherein the template component is used to display a template library including at least one pre-generated special effect template.

[0071] Step S202: In response to a triggering operation on the editing component, running the first editing interface.

[0072] Exemplarily, referring to the application scenario diagram shown in FIG1 , after running the special effects editing application, the special effects editing panel can be displayed first. The special effects editing panel is the upper interface of the first editing interface in the embodiment shown in FIG2 . In the special effects editing panel, at least one template component and an editing component are provided, wherein, on the one hand, the template component is used to display a template library including at least one pre-generated special effects template. In one possible implementation, after the template component is triggered based on a user operation, a third editing page will pop up, and a plurality of different special effects templates will be displayed in the third editing page. In another possible implementation, the template component can directly display the pre-generated special effects panel in a designated area within the special effects editing panel, so that the user can directly select a special effects template from the template library from the special effects editing panel. The pre-generated special effects templates are stored by the template component, so that the user can load different special effects templates for secondary editing or superposition combination by triggering the template component. On the other hand, in response to the triggering operation on the editing component, the first editing interface is run, thereby executing the subsequent steps of generating personalized templates based on the first editing interface.

[0073] Step S203 : in response to the first operation on the liquefied mark, causing a first deformation of the mark outline of the liquefied mark.

[0074] Step S204: In response to the first deformation of the marker outline, a first liquefaction effect is generated in the target area of ​​the template image; wherein the target area is the image area covered by the marker outline of the liquefied marker in the template image, and the first liquefaction effect is used to cause the image elements in the target area to produce a second deformation, and the deformation amount of the second deformation corresponds to the deformation amount of the first deformation.

[0075] Step S205: Generate a target special effect template based on the first liquefaction special effect.

[0076] Step S205A: In response to the fourth operation, setting the first function parameter and / or the second function parameter of the target special effect template;

[0077] Among them, the first function parameter is used to turn on the symmetrical deformation function of the target special effects template, and the symmetrical deformation function is used to generate a second liquefaction special effect symmetrical to the first liquefaction special effect based on the image to be processed; the second function parameter is used to turn on the special effects tracking function of the target special effects template, and the special effects tracking function is used to dynamically set the position of the target area so that the target area tracks the target image element in the image to be processed.

[0078] Exemplarily, after generating the target special effects template, the template function of the target special effects template can be further set. Specifically, in response to the fourth operation, the first function parameter and / or the second function parameter of the target special effects template are set. Exemplarily, a function control for setting the first function parameter and the second function parameter is provided in the special effects editing panel. By setting the function control to the on (On) state or the off (Off) state in response to the fourth operation, the first function parameter and / or the second function parameter are realized. Among them, exemplarily, when the first function parameter is set to a parameter value representing the on state, the symmetrical deformation function of the target special effects template is turned on. After the symmetrical deformation function is turned on, when the target special effects template is used, a second liquefaction effect symmetrical to the first liquefaction effect will be generated in the image to be processed, that is, the liquefaction effect corresponding to the mirror liquefaction identifier in the steps of the above embodiment. For the specific implementation method, please refer to the relevant introduction to the second liquefaction effect in the embodiment shown in Figure 6, which will not be repeated here.

[0079] Furthermore, when the second function parameter is set to a parameter value representing the on state, the special effect tracking function of the target special effect template is turned on. After the special effect tracking function is turned on, when the camera is used for shooting preview and the target special effect template is used, the first liquefaction special effect, or the first liquefaction special effect and the second liquefaction special effect in the target special effect template will automatically track the target image elements, such as the eyes and cheeks of a person's face. That is, the target area corresponding to the first liquefaction special effect will dynamically change according to the image content of the image to be processed, so that the first liquefaction special effect produces a dynamic following visual effect. Among them, the specific implementation method of performing image recognition according to the image content of the image to be processed and tracking the identified target image elements will not be repeated here.

[0080] Step S206: configuring the target special effect template into the template library corresponding to the template component.

[0081] Furthermore, after generating the target special effects template, the target special effects template can be stored in the template library corresponding to the template component in the special effects editing panel by manual triggering or automatic triggering, so that when the user operates the template component, the target special effects template created based on the above steps can be obtained from the template library corresponding to the target component.

[0082] Step S207: running the second editing interface.

[0083] Step S208: In response to the second operation, at least two superimposed special effect templates are added in the second editing interface, wherein the at least two superimposed special effect templates include a target special effect template, and each special effect template is located in a different layer.

[0084] Furthermore, after generating a target special effect template, other special effect templates can be further superimposed based on the generated target special effect template to generate a superimposed special effect template, thereby achieving a superimposed special effect with a mixture of multiple special effects. Specifically, for example, an editing control for triggering a second editing interface is provided in the special effect editing panel. After the editing control is triggered in response to a user operation, the second editing interface is run. Similar to the first editing interface, the second editing interface also displays a sample image for previewing the special effect visual effect, such as a facial image. In one possible implementation, a loading control for loading special effect templates is provided in the second editing interface. After the loading control is triggered, at least two special effect templates can be loaded in sequence, including the target special effect template. Each special effect template is located in a different layer and superimposed on each other. After the at least two special effect templates are loaded, the sample image displays the first liquefaction special effect (or also the second liquefaction special effect) corresponding to the target special effect template and the special effects corresponding to the other special effect templates. The special effect formed by superimposing the first liquefaction special effect and the special effects corresponding to the other special effect templates is the superimposed special effect.

[0085] Figure 11 is a schematic diagram of a superimposed special effect provided by an embodiment of the present disclosure. As shown in Figure 11, after loading special effect templates template_1 and template_2 in the second editing interface, special effect #1 corresponding to special effect template template_1 and special effect #2 corresponding to special effect template template_2 are displayed on the sample image. For example, special effect #1 is a first liquefaction special effect generated based on the steps of the above embodiment, i.e., a custom special effect for enlarging the "mouth"; special effect #2 is an in-app preset special effect for changing facial shape (e.g., a "slim face" special effect); superimposing special effect #1 and special effect #2 may produce the visual effect of the superimposed special effect shown in the figure.

[0086] Optionally, after step S208, the method further includes:

[0087] Step S209: In response to the third operation on the second editing interface, the layer sequence and / or transparency of each special effect template is set.

[0088] For example, after adding a special effect template, each special effect template can be further configured so that the generated superimposed special effect presents different visual effects. Specifically, the terminal device sets the transparency of each special effect template in response to a third operation on the second editing interface, such as a third operation on a slider control within the second editing interface; and sets the image sequence of each special effect template for the editable text box corresponding to each special effect template within the second editing interface. In the steps of this embodiment, by further configuring the layer sequence and transparency of each special effect template in response to the third operation on the second editing interface, the superimposed special effect has richer and more diverse visual effects, thereby enhancing the visual expressiveness of the superimposed special effect template.

[0089] Step S210: generating a superimposed special effect template based on at least two superimposed special effect templates.

[0090] Furthermore, after the special effects template is loaded and adjusted, an overlay special effects template can be generated based on multiple superimposed special effects templates. The overlay special effects template is used in the same way as the target special effects template generated in the previous step, that is, by calling the overlay special effects template, the corresponding overlay special effects synthesized by superimposing multiple special effects can be added to the image to be processed. The specific implementation steps are omitted.

[0091] Furthermore, similar to the target special effects template, after generating the overlay special effects template, the overlay special effects template can be stored in the template library corresponding to the template component in the special effects editing panel by manual triggering or automatic triggering, so as to achieve further superposition of other special effects templates on the basis of the overlay special effects template, and realize a more style-rich overlay special effects template.

[0092] In this embodiment, the implementation of steps S203 to S205 is the same as the implementation of steps S102 to S104 in the embodiment shown in FIG. 2 of the present disclosure, and will not be described in detail here.
