[0039] Figure 1 The present invention is a flowchart of a shooting preview method provided by an embodiment of the present invention. The present invention is applicable to the situation of previewing and editing a shooting object, for example, the scene of previewing and editing a shooting object acquired by a camera. The method can be executed by a shooting preview device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, etc.

[0040] like Figure 1 As shown, the method includes:

[0041] S110 . In response to a shooting preview event, generate a preview image according to the original image and a preset layer configuration file, and display the preview image in a preview interface.

[0042] The preset layer configuration file includes the editing logic of the editing item corresponding to at least one layer. The at least one layer includes a camera layer, a sticker layer, a text layer, a filter layer, etc. The editing item is used to characterize the layer editing method. For example, the editing item includes but is not limited to at least one of the color adjustment, deformation, and special effects of the layer content of the layer. The editing logic is the implementation method of the editing item. The editing logic includes but is not limited to the filter function that implements at least one editing method such as color adjustment, deformation, and special effects.

[0043] In the disclosed embodiment, the preset layer configuration file may represent the configuration information of the layer tree. The layer tree represents the layer group and the layers included in the layer group in a tree structure. The layer is a child node of the corresponding layer group. The editing logic of the editing item corresponding to the layer is the child node of the layer. Figure 2 A schematic diagram of a layer tree structure provided by an embodiment of the present disclosure. Figure 2 As shown, the child nodes of the root node layer 210 of the layer tree 200 include several layer groups 220. The layer group 220 includes several layers 230. The child nodes of the layer 230 include several editing logics 240.

[0044] The shooting preview event is used to trigger the preview operation of the shooting object. For example, if it is detected that the camera has acquired a new shooting object, the shooting preview event is triggered. Or, if it is detected that the original shooting object acquired by the camera has changed, the shooting preview event is triggered.

[0045] The original image refers to a picture or video frame of a photographed object obtained by a camera without image editing. The preview image refers to a picture or video frame displayed on the screen. If necessary, the preview image includes not only a picture or video frame of the photographed object, but also at least one effect material such as sticker material, text, special effect material, etc. The effect material is added to the preview image by layer overlay. In the disclosed embodiment, the original image is used as the input data of the camera layer, and the image is edited by the editing logic of the editing item corresponding to the camera layer, and the edited image data is rendered to the screen to obtain a preview image. The preview interface represents the display interface of the preview image.

[0046] Exemplarily, in response to a shooting preview event, generating a preview image according to an original image and a preset layer configuration file includes: if it is detected that a camera acquires a new original image, triggering a shooting preview event. In response to the shooting preview event, rendering the layer according to the original image and the preset layer configuration file to obtain a preview image corresponding to the original image.

[0047] In some embodiments, the processor establishes a connection with the camera through a setting interface. The camera compares a new frame of the object image obtained by the camera with the previous frame of the object image. If the object is different, the camera reports the new original image of the object. Alternatively, if the object is the same, but the position or posture of the object changes, the camera reports the new original image of the object. If the camera reports a new original image, a shooting preview event is triggered. The processor obtains the new original image reported by the camera.

[0048] In some other embodiments, the processor creates a camera session for managing the camera. A listener can be registered in the camera session to monitor the event of a new frame of raw image acquired by the camera. The new frame of raw image includes an image of a different object from the previously acquired raw image, or an image of the same object but a different position or posture of the object. This listener is triggered each time the camera acquires a new raw image. When the listener is triggered, a shooting preview event is triggered. The processor obtains the new raw image acquired by the camera through a callback function.

[0049] The new original image is used as the input data of the camera layer, and the original image is edited through the editing logic corresponding to the editing item of the camera layer in the preset configuration file to obtain a preview image corresponding to the original image. The preview image is rendered to display the preview image in the preview interface.

[0050] In the disclosed embodiment, if a shooting preview event is triggered, the camera layer is used as the target layer. The input of the camera layer is updated according to the new original image, and the original image is edited according to the filter function corresponding to the edit item of the camera layer, and the edited image is rendered to achieve the effect update of the preview image in the preview interface.

[0051] S120: Determine a target layer in response to a trigger operation in the preview interface.

[0052] Among them, the target layer represents the layer in the selected state in the at least one layer. A candidate layer control set is displayed in the preview interface, and the candidate layer control set includes a candidate layer control corresponding to at least one layer. The candidate layer control is used to select a target layer from at least one layer. The trigger operation in the preview interface includes a layer selection operation or an image processing operation, etc. The layer selection operation may include interactive operations on the candidate layer control. For example, the layer selection operation includes clicking on the candidate layer control to use the layer corresponding to the candidate layer control as the target layer. Further editing can be performed on the target layer. The image processing operation represents the image processing of the preview image, and the layer associated with the image processing operation is used as the target layer to be operated. For example, image processing is performed on a sticker in the preview image, and the layer corresponding to the sticker is used as the target layer. Alternatively, image processing is performed on a target object in the preview image, and the layer corresponding to the target object is used as the target layer.

[0053] Figure 3 A schematic diagram of a preview interface provided by an embodiment of the present disclosure. Figure 3 As shown, a candidate layer control set 320 is displayed in the preview interface 310. If a candidate layer control in the candidate layer control set 320 is clicked, the clicked candidate layer control is converted to a selected state, and the layer corresponding to the clicked candidate layer control is used as the target layer.

[0054] Exemplarily, in response to a trigger operation in the preview interface, determining the target layer includes: displaying a candidate layer control set in the preview interface, the candidate layer control set including a candidate layer control, wherein the candidate layer control is used to select the target layer from the at least one layer. In response to a selection operation on the candidate layer control set, the layer corresponding to the selected candidate layer control is used as the target layer, and a candidate material set corresponding to the target layer is displayed in the preview interface. In response to a selection operation on the candidate material set, the target layer is rendered according to the target material.

[0055] The candidate material set includes candidate materials, and the candidate materials are associated with the type of the layer. For example, if the target layer is a sticker layer, the candidate materials include stickers. If the target layer is a text layer, the candidate materials include artistic fonts. The disclosed embodiments do not specifically limit the meaning of candidate materials.

[0056] In some embodiments, a candidate layer control set is displayed in a preview interface, and the candidate layer control set includes but is not limited to at least one of a sticker layer control, a text layer control, and a special effect layer control. In response to a click operation on the sticker layer control, a sticker layer corresponding to the sticker layer control is used as a target layer. The candidate sticker set is displayed in a preview interface. In response to a selection operation on the candidate sticker set, a target sticker is determined, and a sticker layer is rendered according to the target sticker. The target sticker represents a candidate sticker selected from the candidate sticker set.

[0057] In some other embodiments, in response to a click operation on a text layer control, the text layer corresponding to the text layer control is used as a target layer. In response to a text input operation on the target layer, the text layer is rendered according to the input text.

[0058] Optionally, the determining the target layer in response to the triggering operation in the preview interface includes:

[0059] In response to an image processing operation in the preview interface, a layer corresponding to the image processing operation is used as the target layer. A candidate material set corresponding to the target layer is displayed in the preview interface. In response to a selection operation on the candidate material set, the target layer is rendered according to the target material.

[0060] For example, in response to an image processing operation in the preview interface, where the image processing operation is associated with at least one layer of the preview image, the layer corresponding to the image processing operation is used as the target layer.

[0061] S130. In response to an editing operation on the target layer, obtaining editing parameters, editing the target layer according to the editing parameters and the editing logic, and updating the preview image according to the edited target layer.

[0062] In the disclosed embodiment, the editing operation for the target layer includes the editing operation for the layer content of the target layer. The editing parameter represents the parameter of the editing item corresponding to the editing operation. Optionally, the editing parameter includes at least one of the image editing methods such as color adjustment parameters, deformation degree and special effect parameters. At least one editing item such as color editing item, deformation editing item and special effect editing item corresponding to the target layer is displayed in the preview interface. Optionally, the editing parameter can be adjusted based on the sliding operation of the slider control corresponding to the editing item. In response to the sliding operation of the slider control, the offset of the corresponding editing item is adjusted, and the editing parameter is determined according to the offset. The offset represents the offset distance of the slider in the slider control relative to the original position caused by the sliding operation. The editing parameter is determined according to the offset distance. Alternatively, the offset represents the value or adjustment degree corresponding to the stop position of the slider in the slider control corresponding to the sliding operation. The value or adjustment degree acts on the layer content of the target layer through the editing logic to adjust the display effect of the layer content.

[0063] Exemplarily, a set of candidate edit controls corresponding to the target layer is displayed in the preview interface, wherein the candidate edit controls are used to adjust the edit parameters of the edit item. In response to an adjustment operation on a target edit control, the edit parameters of the target edit item corresponding to the target edit control are obtained, wherein the target edit control represents the candidate edit control to be adjusted in the set of candidate edit controls. Based on the target layer and the target edit item, the edit logic corresponding to the target edit item in the preset configuration file is determined. The target layer is edited according to the edit logic and edit parameters corresponding to the target edit item, and the preview image is updated according to the edited target layer.

[0064] A candidate editing control set of the editing items corresponding to the target layer is displayed in the preview interface. Optionally, the candidate editing control set may include at least one control such as a slider control, a drop-down control, and a color adjustment control. The color adjustment control represents the color adjustment editing item corresponding to the target layer. In response to an adjustment operation on the color adjustment control, a selected target color is determined according to the adjustment operation. The editing logic corresponding to the color adjustment editing item is determined according to a preset configuration file, the target layer, and the color adjustment editing item. In combination with the editing logic and the target color corresponding to the color adjustment editing item, the layer content in the target layer is edited, and the edited target layer and the remaining layers are superimposed to update the preview image.

[0065] In response to the adjustment operation on the target slider control, the slider is controlled to slide in the slider control. When the slider stops sliding, the offset is determined according to the position of the slider and the sliding start position, and the editing parameters of the target editing item are determined according to the offset. The editing logic corresponding to the target editing item is determined according to the preset configuration file, the target layer and the target editing item. In combination with the editing logic and editing parameters corresponding to the target editing item, the layer content in the target layer is edited, and the edited sticker layer and the remaining layers are superimposed to update the preview image.

[0066] Optionally, candidate layout types of the target layer are displayed in the preview interface, and the candidate layout types include fill layout, fixed layout, position follow layout, etc. In response to a selection operation on a candidate layout type, the selected candidate layout type is used as the target layout type. The layout information of the target layer is adjusted according to the target layout type.

[0067] It should be noted that the target layer includes the camera layer, sticker layer, filter layer or text layer, etc. Since each layer is configured with corresponding editing logic, the editing operation on the target layer will not affect other layers. After performing an editing operation on a layer, if you need to return to edit the layer again, you need to select the layer to be edited through the candidate layer control. There is no need to perform region recognition operations, nor is there any need to re-acquire the original image from the camera to start processing, which greatly reduces the consumption of processing resources.

[0068] For example, a set of candidate editing controls corresponding to the preview image and the camera layer is displayed in the preview interface. The candidate editing controls may include deformation controls and special effect controls, etc. Among them, the deformation control is used to adjust the shape of the layer content. For example, the deformation control corresponding to the camera layer can realize the shape change of a specific area of ​​the target object. The target object may include a real portrait, a cartoon character, a model-generated character, a real animal, a cartoon animal, or a model-generated animal, etc. The special effect control is used to adjust at least one of the clarity, contrast, transparency, saturation, and shadow effect of the layer content. In response to the interactive operation of the eye editing control for the portrait face area, the eye editing parameter is obtained. The eye area of ​​the portrait of the preview image is edited in combination with the eye editing parameter and the editing logic corresponding to the eye editing item to update the display effect of the preview image. Alternatively, in response to the interactive operation of the deformation control for the portrait face area, the deformation parameter is obtained. The portrait face area of ​​the preview image is deformed in combination with the deformation parameter and the editing logic corresponding to the deformation editing item to update the display effect of the preview image.

[0069] Further, in response to a click operation of the sticker layer control, the sticker layer is converted to a selected state, and the camera layer is converted to a non-selected state. A candidate material set corresponding to the sticker layer is displayed on the preview interface. The candidate materials include sticker materials, etc. In response to a selection operation on the candidate material set, the selected sticker material is used as a target sticker material. The target sticker material is used as input data of the sticker layer to render the sticker layer based on the target sticker material. The sticker layer and the camera layer are superimposed to adjust the display effect of the preview image according to the target sticker material. A preview image with the target sticker material and a candidate editing control set corresponding to the sticker layer are displayed on the preview interface. The candidate editing control may include at least one control such as a color adjustment control, a deformation control, and a special effect control. Among them, the color adjustment control is used to adjust the color of the target sticker material. In response to an interactive operation on the color adjustment control, a target color parameter of the target sticker material is obtained. The color of the target sticker material is adjusted in combination with the editing logic corresponding to the target color parameter and the color adjustment editing item to update the target sticker material in the preview image, so as to achieve an updated display effect of the preview image.

[0070] Further, in response to a click operation of the text layer control, the text layer is converted to a selected state, and the sticker layer is converted to a non-selected state. A candidate material set of the text layer is displayed in the preview interface. Among them, the candidate materials include text templates of different fonts, etc. In response to the selection operation on the candidate material set, the text content is input according to the selected text template. The text content is used as input data of the text layer to render the text layer based on the text content. The text layer, sticker layer and camera layer are superimposed to adjust the display effect of the preview image according to the text content. In the preview interface, not only a preview image with text content and target sticker material is displayed, but also a candidate editing control set is displayed. Among them, the candidate editing controls include but are not limited to at least one of a color adjustment control, a deformation control, a special effect control, etc. In response to the interactive operation on the deformation control, the deformation parameters of the text content are determined. The shape of the text content is adjusted in combination with the deformation parameters and the deformation filter function to update the text content in the preview image, so as to achieve the display effect of updating the preview image.

[0071] After editing the layer content of the text layer, if you need to return to readjust the eye area of ​​the target object in the preview image, you can select the camera layer through the candidate layer control set in the preview interface, and obtain new eye editing parameters based on the interactive operation of the eye editing control corresponding to the camera layer, and update the eye area of ​​the preview image according to the new eye editing parameters and editing logic.

[0072] The technical solution of the disclosed embodiment, in response to the shooting preview event, generates a preview image according to the original image and the preset layer configuration file, and displays the preview image in the preview interface. The preset layer configuration file includes the editing logic of the editing item corresponding to at least one layer. In response to the triggering operation in the preview interface, the target layer is determined. In response to the editing operation for the target layer, the editing parameters are obtained, the target layer is edited according to the editing parameters and the editing logic, and the preview image is updated according to the edited target layer. By adopting the above technical solution, multiple layers can be pre-configured by the preset layer configuration file, and the editing logic of the editing items corresponding to the layers can be configured, so that when the shooting preview event is triggered, the preview image can be generated according to the original image and the preset layer configuration file, and the target layer is determined according to the triggering operation, and the target layer is edited separately without affecting the content of other layers, and the preview image can be updated according to the edited target layer, so as to realize the flexible selection of layers for editing, and after editing, the edited layer can be returned to for re-editing, which solves the problem of lack of flexibility in the general preview image editing method.

[0073] Figure 4 This is a flow chart of another shooting preview method provided by an embodiment of the present disclosure. Based on the above embodiment, the embodiment of the present disclosure additionally defines the steps related to adjusting the layer layout. Figure 4 As shown, the method includes:

[0074] S410: In response to a shooting preview event, generate a preview image according to the original image and a preset layer configuration file, and display the preview image in a preview interface.

[0075] The preset layer configuration file includes the editing logic of an editing item corresponding to at least one layer, and the editing item is used to represent the layer editing mode.

[0076] S420: In response to a trigger operation in the preview interface, determine a target layer, wherein the target layer represents a layer in a selected state among the at least one layer.

[0077] S430. In response to an editing operation on the target layer, obtaining editing parameters, editing the target layer according to the editing parameters and the editing logic, and updating the preview image according to the edited target layer.

[0078] S440: Obtain a new original image.

[0079] The new original image includes the target object.

[0080] Exemplarily, a new original image is obtained by querying the camera cache or a callback function. If the new original image is a picture or video frame of the same subject as the preview image but with a different pose, a layer shift event is triggered to perform subsequent operations to adjust the position of the layer to be shifted. For example, the face position of the target portrait in the new original image is different from that of the target portrait in the preview image. Alternatively, the position of the target portrait in the new original image is different from that of the target portrait in the preview image.

[0081] S450: Determine a layer to be shifted according to the layout type and target object of the at least one layer.

[0082] The disclosed embodiment can set the layout type of each layer, and can also set the global layout type. Among them, the global layout type can be effective for multiple layers. That is, by configuring the global layout type and the multiple layers corresponding to the global layout type, the layout type of the multiple layers is determined. According to the position correspondence between at least one layer and the target object in the original image and the layout type, the layer to be shifted in at least one layer is determined. For example, if the global layout type is set to position follow layout, and the layers corresponding to the position follow layout are set to include layer A, layer B, layer C and layer D. Then, if the position of the target object changes, or the face position of the target object changes, the layers in layer A, layer B, layer C and layer D that have a position correspondence with the target object are used as layers to be shifted. For example, there is sticker a on the face of a portrait. If the position of the face of the portrait changes, the sticker layer corresponding to sticker a is used as the layer to be shifted to maintain the relative position relationship between sticker a and the face of the portrait.

[0083] S460: Update the position of the layer to be shifted according to the position information of the target object in the new original image, and update the preview image corresponding to the new original image according to the updated layer to be shifted.

[0084] Exemplarily, the position correspondence between the portrait and the layer content in the layer to be shifted is determined based on the position information of the portrait in the preview image and the position information of the layer content in the layer to be shifted. The position offset information of the layer content in the layer to be shifted is determined based on the position information and the position correspondence of the portrait in the new original image. The position of the layer to be shifted is updated based on the position offset information. The layer to be shifted after the position update is superimposed with the remaining layers to update the display position of the layer to be shifted in the preview image corresponding to the new original image.

Figure 5As shown, there is a sticker material 520 on the left side of the face of the person in the preview image 510, and a target text 530 is set at the head of the preview image 510. If the person in the new original image tilts his head to the right, the position of the sticker layer is adjusted to maintain the relative position relationship between the sticker material 520 and the face of the person.

[0086] The technical solution of the disclosed embodiment is to obtain a new original image, determine the layer to be shifted according to the layout type of at least one layer, update the position of the layer to be shifted according to the position information of the target object in the new original image, and update the preview image corresponding to the new original image according to the updated layer to be shifted. Through the above technical solution, when the position of the target object in the new original image is moved, the layer to be shifted in at least one layer can be determined according to the position correspondence between at least one layer and the target object and the layout type, and the position of the layer to be shifted can be updated according to the position information of the target object in the new original image, so as to maintain the relative position relationship between the layer to be shifted and the target object after the position of the target object is moved.

[0087] Figure 6 This is a flowchart of another shooting preview method provided by the embodiment of the present disclosure. Based on the above embodiment, the embodiment of the present disclosure additionally defines the steps related to the layer cache. Figure 6 As shown, the method includes:

[0088] S610: In response to a shooting preview event, generate a preview image according to the original image and a preset layer configuration file, and display the preview image in a preview interface.

[0089] The preset layer configuration file includes the editing logic of an editing item corresponding to at least one layer, and the editing item is used to represent the layer editing mode.

[0090] S620: In response to a layer cache event, determine target cache data according to layer content of the layer in the layer group, and cache the target cache data corresponding to the layer group.

[0091] Wherein, the layer group represents a collection of layers. The correspondence between the layer group and the layer can be defined in a preset layer configuration file. Alternatively, the layers can be grouped and processed according to the order of multiple layers corresponding to the preview image to obtain the layer group. The number of layers included in the layer group can be preset. Optionally, the number of layers included in the layer group can be flexibly adjusted based on the storage space of the storage resources of the electronic device. For example, the storage resources include memory, etc.

[0092] Layer cache events are used to trigger layer cache operations. The conditions for triggering layer cache events include timed triggering, triggering at a set time interval, or triggering based on layer rendering progress. Layer rendering progress represents the ratio of the rendered and unrendered input data of the layer. For example, a layer cache event can be triggered after the layer rendering is completed.

[0093] The layer content represents the data content drawn on the layer. For example, the layer content of the camera layer includes the image content of the photographed object. The layer content of the sticker layer includes the layer content of the sticker material. The layer content of the text layer includes text. The embodiments of the present disclosure do not specifically limit the specific meaning of the layer content.

[0094] The target cache data represents the superposition result of the layer contents of the layers in the layer group. Assuming that the layer group includes layer A, layer B, and layer C, the target cache data corresponding to the layer group can be the media data obtained by superimposing layer A, layer B, and layer C. The media data includes but is not limited to images, texts, special effects animations, etc.

[0095] Exemplarily, if at least one layer group meets the layer group cache time, a layer cache event for at least one layer group is triggered. For any layer group that meets the layer cache time, target cache data is determined according to the layer content of the layer in the layer group, and the target cache data corresponding to the layer group is cached.

[0096] Alternatively, if the cache interval of at least one layer group meets the set time interval threshold, a layer cache event for at least one layer group is triggered. For any layer group that meets the time interval threshold, target cache data is determined according to the layer content of the layer in the layer group, and the target cache data corresponding to the layer group is cached.

[0097] Alternatively, if the rendering of the layers in at least one layer group is completed, a layer cache event for at least one layer group is triggered. For any layer group that has been rendered, target cache data is determined according to the layer content of the layers in the layer group, and the target cache data corresponding to the layer group is cached.

[0098] By caching the target cache data corresponding to the layer group, you can reduce rendering overhead and avoid caching the layer content of each layer to occupy more storage resources.

[0099] Optionally, since the overall image zooming operation is usually not performed in the preview scene, for any layer group, the target cache data is determined according to the layer content of the layer in the layer group, and the target cache data corresponding to the layer group is cached according to the screen size. Since the target cache data of the screen size can be cached, the storage resource usage is reduced, the storage resource is saved, and the effect of balancing the rendering overhead and the cache overhead is achieved.

[0100] S630: Determine a target layer in response to a trigger operation in the preview interface.

[0101] Exemplarily, if the target layer is not a cached layer, in response to a selection operation on the candidate layer control set, the layer corresponding to the selected candidate layer control is used as the target layer, and the candidate material set corresponding to the target layer is displayed on the preview interface. In response to a selection operation on the candidate material set, the target layer is rendered according to the target material.

[0102] If you need to edit a cached layer, determine the target layer through the trigger operation in the preview interface.

[0103] S640: If the target layer is a cached layer, obtain target cache data corresponding to the target layer group.

[0104] Wherein, the target layer group includes the target layer.

[0105] Exemplarily, the target cache data corresponding to the target layer group to which the target layer belongs in the cache is obtained. Optionally, the target layer group to which the target layer belongs is determined according to the correspondence between the layer and the layer group. According to the identification information of the target layer group, the target cache data corresponding to the target layer group is obtained from the cache.

[0106] S650: Render the layers included in the target layer group according to the target cache data corresponding to the target layer group to obtain the target layer.

[0107] Exemplarily, the target cache data corresponding to the target layer group is split into layers to obtain the layer content of each layer included in the target layer group, and layer rendering is performed based on the layer content of each layer to obtain the target layer.

[0108] S660: In response to an editing operation on the target layer, obtaining editing parameters, editing the target layer according to the editing parameters and the editing logic, and updating the preview image according to the edited target layer.

[0109] The technical solution of the disclosed embodiment, in response to a layer cache event, determines target cache data according to the layer content of the layers in the layer group, and caches the target cache data corresponding to the layer group, which can reduce rendering overhead and avoid the situation where the cached layer content of each layer occupies more storage resources, thereby achieving the effect of balancing rendering overhead and cache overhead.
