[0013] It should be noted that the modifications "one" and "multiple" referred to in this disclosure are exemplary, and one of ordinary skill in the art will understand that they should be understood as "one or more" unless the context clearly indicates otherwise.

[0014] 1 is a schematic flowchart of a photographing method provided by an embodiment of the present disclosure. The method may be performed by a photographing device, where the device may be implemented by software and / or hardware and located in an electronic device, typically a mobile phone or tablet computer. The photographing method provided by an embodiment of the present disclosure is suitable for a scenario in which at least one of a user's photographing posture, a photographing angle, and a photographing distance is guided. As shown in FIG. 1, the photographing method provided by this embodiment may include the following steps:

[0015] S101: In response to a trigger operation for guiding photography using a target posture template, display the target posture template on an upper layer of a preview screen displayed on a photography page, and display photography prompt information on the photography page, where the target posture template is used to guide and prompt a photography posture corresponding to a photography object, and the photography prompt information includes at least one of photography angle prompt information and photography distance prompt information.

[0016] In this embodiment, the shooting guidance trigger operation is a trigger operation that instructs the electronic device to guide the shooting posture using a target posture template, i.e., a trigger operation that instructs the electronic device to display the target posture template, such as an operation to select or introduce a posture photo. The target posture template is a posture template that the user wants to use for shooting guidance, for example, a template corresponding to the posture photo selected or introduced by the user, and the template may be a posture outline template, i.e., a wireframe composed of the outline of a character. The target posture template is used to prompt and guide the shooting subject to take a corresponding shooting posture for shooting. The shooting subject can be understood to be an object photographed by the electronic device, such as a character or animal photographed by the electronic device. The following description will be given taking the example of a character as the shooting subject.

[0017] The photographing prompt information can be understood as photographing prompt information periodically generated on the current preview screen (i.e., the preview screen collected by the camera at the current time), and the information content of the current photographing prompt information can be set as needed. For example, the photographing prompt information includes at least one of current key part scale information, prompt information on the relative size between the current key part scale information and the preset key part scale information, and photographing correction information. That is, the current key part scale information can be used as the photographing prompt information to be currently displayed, and the photographing prompt information to be currently displayed can be generated based on the relative size between the current key part scale information and the preset key part scale information. Alternatively, the photographing correction information can be determined based on the deviation information between the current key part scale information and the preset key part scale information, and the photographing correction information can be used as the current photographing prompt information. Here, the current key part scale information may include head scale information and / or leg scale information of the subject being photographed on the current preview screen, and the prompt information for the relative size between the current key part scale information and the preset key part scale information may be information for prompting the relative size, for example, information for prompting that the head scale / leg scale is too large or too small, and the shooting correction information may be information for correcting the user's current shooting defects, such as prompting the user to increase the shooting distance (for example, move the camera backward) or adjust the shooting angle downward (for example, move the camera downward) when, for example, the head scale of the subject being photographed on the current preview screen is too large or the leg scale of the subject being photographed on the current preview screen is too small.

[0018] 2 , when a user wants to use a posture template 20 to guide a photograph, the user may perform a trigger operation to use the posture template 20 to guide a photograph. Correspondingly, when the electronic device detects the user's trigger operation, the electronic device displays the posture template 20 on top of the preview screen displayed on the photographing page, and while displaying the posture template 20, periodically generates current photographing prompt information 21 (i.e., photographing prompt information at the current time) and displays the current photographing prompt information 21 on the photographing page. For example, when the photographing prompt information is first displayed (i.e., when the photographing prompt information 21 is not displayed on the photographing page), the electronic device may generate the current photographing prompt information 21 according to the current preview screen and display the current photographing prompt information 21 on the photographing page. When the photographing prompt information is displayed on the photographing page, the electronic device generates the current photographing prompt information 21 according to the current preview screen and updates the photographing prompt information displayed on the photographing page to the current photographing prompt information 21.

[0019] In the above embodiment, the display method of the posture template on the photographing page can be set as needed, for example, the posture template can be directly displayed at a preset display position on the photographing page, or, taking into account the composition effect of the photographed photo / video frame, the posture template can be selectively displayed at the display position of the posture template in the corresponding posture photo, that is, at the same display position as the original display position of the posture template in the corresponding posture photo.

[0020] In the above embodiment, the method for determining the current shooting prompt information can be flexibly set. Optionally, the shooting prompt information is generated based on key part scale information, which is the key part scale information of the shooting object in the preview screen. For example, the current key part scale information is determined based on the current preview screen collected by a camera, where the current key part scale information is the key part scale information of the shooting object in the current preview screen collected by a camera, and the current shooting prompt information is generated based on the current key part scale information.

[0021] In one embodiment, the current key part scale information can be understood as the key part scale information of the photographer in the current preview screen. The key part scale information may be scale information between the key part of the subject and the photographer's body, or scale information between the key part of the subject and a preset part of the subject. Hereinafter, an example will be described in which the key part scale information is scale information between the key part of the subject and a preset part of the subject. The key part includes at least one of the head and the legs, and the scale information may be length scale information, for example, scale information in a direction parallel to the body, and the preset part may be the upper body of the subject (for example, including or excluding the head).

[0022] In one embodiment, during the process of displaying the target posture template, the electronic device periodically determines current key part scale information of the subject to be photographed in the current preview screen collected by the camera, and displays or updates the photographing prompt information displayed on the photographing page based on the current key part scale information.

[0023] For example, a model (e.g., a posture identification model) capable of identifying key point information of the subject may be obtained by pre-learning. Accordingly, when a photography page is displayed, a current preview screen captured by a camera is periodically acquired, the current preview screen is input to a posture identification model, and key point information of the subject in the current preview screen output from the posture identification model is acquired as current posture information of the subject. Based on the current posture information, key parts and preset parts of the subject are identified. Length information of the key parts of the subject in the preview screen and length information of the preset parts in the preview screen are acquired. Based on the length information, length scale information between the key parts and preset parts of the subject is calculated as current key part scale information of the subject. Current photography prompt information is generated based on the current key part scale information. Here, the key points of the subject may be set as needed, and may include, for example, contour points of the subject in the current preview screen, i.e., points constituting the character contour of the subject in the current preview screen, or points constituting key parts (e.g., legs, head, etc.) of the subject in the current preview screen.

[0024] Taking the example of a case where the key parts include the head and legs, the preset parts are the upper body (excluding the head) of the subject to be photographed, and the subject is standing upright, length information of the head, legs, and upper body of the subject to be photographed in the vertical direction of the photographing screen is determined based on the key point information of the subject to be photographed in the current preview screen, head scale information of the subject to be photographed in the current preview screen is calculated based on the length information of the head and length information of the upper body of the subject, and leg scale information of the subject to be photographed in the current preview screen is calculated based on the length information of the legs and length information of the upper body of the subject, thereby making it possible to obtain current key part scale information of the subject to be photographed.

[0025] Furthermore, for example, as shown in FIG. 2, when a posture template 20 is displayed on the shooting page, a posture photo 22 corresponding to the posture template 20 is displayed on the shooting page, i.e., the posture photo 22 that serves as the basis for generating the posture template 20 is displayed, making it easier for the user to clarify the subject and environment of the posture photo 22 corresponding to the shooting template 20.

[0026] In this embodiment, a posture template and shooting prompt information are displayed, which guides the subject to the shooting posture through the posture template, prompts the subject to shoot through the shooting prompt information, and guides the subject to a good shooting posture. This avoids the situation where the subject has an appropriate body scale in the current preview screen, and the subject's shooting posture is not good in the captured video or photo, and the subject's body scale is not coordinated (for example, the head is too large or the legs are too short), thereby improving the quality of the captured video or photo.

[0027] In one embodiment, when a trigger operation is received to guide photography using the target posture template, if light supplementation is required, the supplementation is performed using a fill light, so that the photographed image has a good lighting effect. In this case, the photography method provided by this embodiment optionally further includes controlling the fill light in response to a trigger operation to guide photography using the target posture template, so that the supplementation is performed using light corresponding to the photography environment information of the photographed object.

[0028] For example, when a trigger operation for guiding photography using a target posture template is received, the target posture template and photography prompt information are displayed on the photography page. Light information, such as at least one of light direction information, brightness information, and color information, is determined based on the photography environment information of the subject or the photography environment information of the subject and the light information in the posture photo corresponding to the target posture template, and the corresponding fill light is controlled to provide assistance using the light corresponding to the light information. Here, the fill light may be a fill light provided by the electronic device itself or a fill light connected to the electronic device. The photography environment information of the subject may include external light information of the subject, i.e., light information of the photography environment in which the subject is located.

[0029] S102: In response to a photographing command, the camera is controlled to photograph the subject.

[0030] In one embodiment, when the electronic device receives a shooting command, it controls the camera to shoot an object, for example, to take a photo or a video.

[0031] In one embodiment, the shooting command may be a command to instruct the electronic device to take a photo, such as a photo command or a video shooting command, and may be automatically generated by the electronic device when the current conditions satisfy the preset generation conditions, or may be generated based on a received shooting operation (e.g., a trigger operation acting on the shooting control), i.e., the electronic device may take a photo automatically, or may take a photo based on a user's trigger operation.

[0032] In one embodiment, before controlling the camera to take a photograph in response to the received photographing command, the method further includes at least one of calculating a screen picture score of the current preview screen based on at least one of matching information between the current posture information of the subject and the target posture template and facial expression information of the subject, and generating a photographing command if the screen picture score is higher than a preset threshold; and generating a photographing command if a photographing operation operating within the photographing page is received.

[0033] In one embodiment, when the target posture template is displayed, the electronic device periodically calculates a degree of similarity between the current posture information of the subject and the target posture template, evaluates the current preview screen according to the degree of similarity and at least one of facial expression information of the subject in the current preview screen (e.g., the degree of smiling face and / or the degree of eye opening of the subject), calculates a screen picture score for the current preview screen, generates an automatic shooting command if the screen picture score is higher than a preset threshold, and does not perform an operation to generate an automatic shooting command if the screen picture score is lower than the preset threshold. Optionally, when a user wants to take a picture, the electronic device may trigger a shooting control 23 (shown in FIG. 2 ) in the shooting page. When the electronic device detects that the user has triggered the shooting control 23, it determines that a shooting operation instructing the electronic device to take a picture has been received, and generates a shooting command in response to the shooting operation.

[0034] The photography method provided by this embodiment responds to a trigger operation to guide photography using a target posture template by displaying a target posture template used to prompt the photographer to take a photography posture corresponding to the subject on the upper layer of the preview screen displayed on the photography page, and displays photography prompt information on the photography page, where the photography prompt information includes at least one of photography angle prompt information and photography distance prompt information, and controls the camera to photograph the subject in response to a photography command. By guiding the photography posture through the posture template and prompting at least one of the photography angle and photography distance through the photography prompt information, this embodiment solves the problem that the subject has difficulty in taking a posture when photographing, so that the subject has an appropriate body scale in the captured photo / video, which improves the photography effect of the subject and reduces the difficulty of photography.

[0035] 3 is a schematic flowchart of another photography method provided by an embodiment of the present disclosure. The solution in this embodiment may be combined with one or more selectable solutions in the above embodiments. Optionally, the trigger operation is a selection operation for a recommended posture photo corresponding to a target posture template, and the photography method provided by this embodiment further includes the steps of: displaying a recommended posture list in response to a posture recommendation operation performed in a photography page, where the recommended posture list is used to display the recommended posture photo, and the photography information of the recommended posture photo matches the target photography information of the photography target when receiving the template recommendation operation, and the target photography information includes at least one of posture information and photography environment information.

[0036] The method further includes a step of selectively determining target shooting information of a shooting subject when the template recommended operation is received, before displaying the recommended posture list, and acquiring a recommended posture photo whose shooting information matches the target shooting information.

[0037] Optionally, the trigger operation is a posture photo introduction operation, and the method further includes a step of obtaining an introduction posture photo corresponding to the posture photo introduction operation and generating the target posture template based on the introduction posture photo before displaying the target posture template in the upper layer of the preview screen displayed on the shooting page.

[0038] Optionally, the photographing command is a photographing command, and further includes a step of controlling the camera to photograph, then retouching the photographed original image to obtain a target photograph, and saving the original image and the target photograph.

[0039] Correspondingly, for example, as shown in FIG. 3, the photographing method provided in this embodiment includes the following steps:

[0040] S201: In response to a posture recommendation operation performed within a photography page, determine target photography information of a photography subject when the template recommendation operation is received, and obtain a recommended posture photo whose photography information matches the target photography information, wherein the target photography information includes at least one of posture information and photography environment information.

[0041] In this embodiment, the posture recommendation operation may be an operation to instruct the electronic device to display a recommended posture list, for example, an operation to trigger a recommended posture control displayed on the photography page. The target photography information may be understood as photography information of the photography subject at the time the posture recommendation operation is received, and may include at least one of posture information and photography environment information. The posture information may be understood as information for characterizing the photography posture of the photography subject, for example, position information of key points of the photography subject. The photography environment information may be understood as information for characterizing the photography environment in which the photography subject is located, such as photography background information and external light information.

[0042] In one embodiment, the electronic device displays a photography page as shown in FIG. 4. Therefore, when a photographer wants to instruct the electronic device on a recommended photography posture, the photographer either assumes their preferred posture (if the photographer is the subject) or instructs the subject on their preferred posture (if the photographer is not the subject), triggering the posture recommendation control 40 in the photography page. Correspondingly, when the electronic device detects that the user has triggered the posture recommendation control 40 in the photography page, the electronic device determines that a posture recommendation operation has been received, and in response to the posture recommendation operation, determines target photography information of the subject based on a preview image collected by the current camera, for example, inputs the preset image into a posture detection model obtained by pre-learning, determines target photography information of the subject based on the posture detection model, and acquires a recommended posture photo based on the target photography information.

[0043] In this embodiment, the electronic device directly determines and acquires recommended posture photos based on the target shooting information. For example, the electronic device acquires the shooting information of each posture photo in a posture photo library, calculates the degree of match between the shooting information of each posture photo and the target shooting information, and selects a certain number of posture photos in descending order of the degree of match as recommended posture photos, or selects posture photos with a degree of match exceeding a preset threshold value as recommended posture photos, and acquires the determined recommended posture photos.

[0044] The electronic device may also determine a recommended posture photo based on the target shooting information via a server. For example, the electronic device may generate a posture photo acquisition request including the target shooting information, send the posture photo acquisition request to a server, and request the server to return recommended posture photos whose shooting information matches the target shooting information. After receiving the posture photo acquisition request from the electronic device, the server analyzes the posture photo acquisition request, acquires the target shooting information included in the posture photo acquisition request, calculates the degree of match between the shooting information of multiple posture photos in the posture photo library and the target shooting information, and selects a certain number of posture photos in descending order of degree of match as recommended posture photos, or selects posture photos whose degree of match exceeds a preset threshold as recommended posture photos, and transmits the determined recommended posture photos to the electronic device. In response, the electronic device can receive the recommended posture photos returned from the server.

[0045] In one embodiment, posture photos in the posture photo library are preset, that is, photos with high photographic effect are acquired in advance as posture photos, and posture templates corresponding to them may be stored in the posture photo library.

[0046] S202, display a recommended posture list, where the recommended posture list is used to display recommended posture photos.

[0047] In one embodiment, after acquiring the recommended posture photos, the electronic device displays a recommended posture list 50 on the photography page, and displays the acquired recommended posture photos in the recommended posture list 50, and may allow selection by the photographer or the subject to be photographed, for example, as shown in FIG. 5 .

[0048] In this embodiment, posture photos are recommended to the user based on the shooting information of the subject at the current time, and the user's posture is guided by posture templates corresponding to the posture photos, allowing the subject to easily adopt their preferred posture in the current shooting environment. Similar high-quality postures are recommended to the user based on the shooting environment and the preferred posture of the subject, allowing the subject to fine-tune their preferred posture to achieve good shooting effects. This eliminates the need for the subject to manually select and shoot their preferred posture from a large number of posture photos, and solves the problem of the subject not being able to adopt a good posture during the shooting process, thereby improving the effect of photo / video shooting and reducing the time required to select a posture template and the difficulty of taking photos / videos.

[0049] In one embodiment, when the user closes the recommended posture list without selecting any of the recommended posture photos, shooting prompt information may be displayed only on the photography page, and the user may be prompted to take a photograph by the shooting prompt information. In this case, after the recommended posture list is displayed, in response to a list closing operation when a target posture photo is not selected, the display of the recommended posture list is canceled, and the shooting prompt information is displayed on the photography page.

[0050] In the above embodiment, when no recommended posture photo is displayed in the recommended posture list, i.e., when no recommended posture photo whose shooting information matches the target shooting information is obtained, or when the user does not want any of the recommended posture photos displayed in the recommended posture list, for example, when the user is not satisfied with any of the shooting postures in the recommended posture photos displayed in the recommended posture list, an operation to close the recommended posture list (i.e., a list closing operation) may be performed. In response to this, when the electronic device detects the user's list closing operation, it may stop displaying the recommended posture list on the shooting page and display shooting prompt information on the shooting page.

[0051] S203: receiving a selection operation for a recommended posture photo corresponding to the target posture template, and executing S206;

[0052] In this embodiment, the selection operation may be an operation of selecting one of the recommended posture photos displayed in the recommended posture list, for example, an operation of clicking on the recommended posture photo.

[0053] 5, the electronic device displays a recommended posture list 50 and displays each recommended posture photo in the recommended posture list 50. This allows the user to trigger the recommended posture photo when taking a photo in a posture included in the recommended posture photo. Correspondingly, when the electronic device detects that the user has triggered the recommended posture photo, the electronic device sets the posture template corresponding to the recommended posture photo as a target posture template and determines that a selection operation for the posture photo corresponding to the target posture template has been received, i.e., determines that a trigger operation for employing the target posture template to guide photography has been received.

[0054] In this embodiment, the target posture template may be sent to the electronic device by the server, or may be generated by the electronic device based on the corresponding recommended posture photo. That is, the server may send each recommended posture photo to the electronic device and simultaneously send a posture template corresponding to each recommended posture photo to the electronic device, or the server may send only each recommended posture photo to the electronic device, so that when the electronic device detects that the user has triggered a recommended posture photo in the recommended posture list, it can generate a corresponding target posture template based on the recommended posture photo.

[0055] In addition, when the electronic device receives a selection operation for a posture photo corresponding to a target posture template, in addition to executing S208, the electronic device may close the recommended posture list to make it easier for the user to view the preview screen and the target posture template.

[0056] S204: receiving a posture photo introduction operation;

[0057] S205: obtaining an introduction posture photo corresponding to the posture photo introduction operation, and generating the target posture template based on the introduction posture photo;

[0058] In this embodiment, the posture photo introduction operation triggers a posture photo introduction operation, for example, a posture photo introduction control in a photography page, and performs an operation of selecting and introducing a certain photo. The introduced posture photo can be understood as the introduced posture photo.

[0059] In this embodiment, the electronic device can adopt a posture template corresponding to the posture photo introduced by the user to guide the user in taking pictures.

[0060] In one embodiment, the electronic device displays a photographing page, as shown in FIG. 4. When the user takes a photograph in a photographing posture in a preferred posture photo, the user triggers a posture photo introduction control 41 on the photographing page to select and introduce the preferred posture photo. In response, the electronic device can acquire the posture photo introduced by the user and generate a posture template corresponding to the posture photo based on the posture photo. For example, the electronic device can input the introduced posture photo into a posture detection model obtained by pre-learning, acquire keypoint information of one or more objects captured in the introduced posture photo output from the posture detection model, and generate a posture template corresponding to the posture photo based on the keypoint information. For example, the electronic device can sequentially connect keypoints located on the outline of the corresponding object in the photograph in a clockwise or counterclockwise direction to obtain a wireframe of the object, which serves as the posture template corresponding to the introduced posture photo.

[0061] Furthermore, after obtaining the posture template corresponding to the introductory posture photo, the introductory posture photo and the posture template may be uploaded to a server and stored, for example, in a custom space corresponding to the user in a posture photo library, so that subsequent users can use the posture template again to guide them in the shooting posture, or the posture photos available to each user stored in the posture photo library and the introductory posture photo stored in the user's custom space may be selected as posture photos recommended for the user.

[0062] S206: Display the target posture template on the upper layer of the preview screen displayed on the shooting page, and display shooting prompt information on the shooting page, where the target posture template is used to guide the user to prompt for a shooting posture corresponding to the shooting object, and the shooting prompt information includes at least one of shooting angle prompt information and shooting distance prompt information.

[0063] S207: In response to the photography command, the camera is controlled to photograph the subject.

[0064] S208: The original image obtained by photographing is retouched to obtain a target photograph, and the original image and the target photograph are saved.

[0065] In this embodiment, the original image may be a photograph that has been taken, and the target image may be a photograph obtained by retouching the original image.

[0066] In this embodiment, if the photography command is an image capture command, the captured original image may be retouched after the image capture is completed to improve the user's experience.

[0067] For example, the electronic device may capture an original image, input the original image into a retouching model obtained by pre-learning, retouch the original image using the retouching model to obtain a target image, simultaneously store the captured original image and the target image, and display the original image or the target image, or display the original image and the target image in correspondence with each other. Here, the retouching model is used to retouch an input image (e.g., an original image) and output the retouched target image, and may be obtained by pre-learning.

[0068] When a posture template is used to guide the photographic posture of the subject during photographing to improve the retouching effect of the original image, in this embodiment, the original image obtained by photographing a posture photo corresponding to the posture template used during photographing the original image is retouched, so that the retouched target photograph and the retouched posture photo have the same or similar photographic effect, and the retouched original image is more in line with the actual photographic intention of the user (e.g., the photographer and / or the photographic subject). In this case, optionally, retouching the photographed original image to obtain the target photograph includes retouching the original image based on photographic information of the target posture photo corresponding to the target posture template to obtain the target photograph, where the photographic information includes color information and / or image information of the target object in the target posture photo, and the image information includes dimension information and / or position information.

[0069] In this embodiment, the target pose template may be the pose template used when capturing the original image. The target pose photo may be a pose photo corresponding to the target pose template. The target object may be understood to be an object corresponding to the target pose template in the target pose photo, such as a character and / or an animal corresponding to the target pose template. The color information of the target pose photo may be understood to be color information of the target pose photo, such as filter information used in the target pose photo.
