Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Among them, after a large amount of user feedback, a large amount of users are dissatisfied with the quality of an image (for simplicity of description, the image is taken as an example here, but is not taken as an exclusion of a video and the like) photographed by using the terminal, resulting in poor photographing experience of the users.

Thus, a need for improving the user's shooting experience is addressed.

In order to improve the shooting experience of the user, the quality of the image shot by the user using the terminal can be improved.

In order to improve the quality of images shot by a user by using a terminal, the inventor carries out statistical analysis on the situation that the quality of the images shot by using the terminal is not satisfactory and fed back by a large number of users and finds that: among images taken by a large number of users using a terminal, there are many images whose composition is not standard (e.g., does not meet aesthetic standards for composition, etc.).

In view of the situation of the composition being not standard, the inventor inquires about users who shoot images with composition being not standard, so as to obtain the reason that the users are not satisfied with the quality of the images shot by using the terminal, and basically: the composition of an image photographed using the terminal is not satisfactory.

As such, the inventors can conclude that the reason why these users are not satisfied with the quality of images captured using terminals is that the composition of images captured using terminals is not standardized.

In view of this, the inventors have thought of the need to improve the quality of images taken by a user using a terminal for composition.

However, the inventors found that: if it is necessary to make the composition of an image photographed by a user using a terminal standard or close to standard, it is often necessary to make a photographer have professional photographic knowledge (for example, at least the ability to "consider the positions and corresponding postures of important elements in a scene in the image from the viewpoint of composition aesthetics") to photograph an image whose composition is standard or close to standard, otherwise, it is difficult to photograph an image whose composition is standard or close to standard.

Further, the inventors found again that: among users who take images using a terminal, most users are not professional photographers, that is, most users are amateur and do not have professional photographic knowledge, and thus it is difficult to take images whose composition is standard or close to standard.

In view of the above, in order to enable a user without professional photographic knowledge to capture an image whose composition is standard or close to standard using a terminal, professional assistance may be provided to the user without professional photographic knowledge to assist the user without professional photographic knowledge to capture an image whose composition is standard or close to standard using the terminal, so that the quality of the image captured by the terminal of the user without professional photographic knowledge may be improved, and the capturing experience of the user without professional photographic knowledge may be improved.

In one embodiment, in order to assist a user who does not have professional photographic knowledge to shoot an image with a standard or near standard composition by using a terminal, in the process of shooting the image by using the terminal, when the terminal shoots a preview image (the preview image comprises a shot object) by using a camera, the preview image can be displayed on a shooting interface of the terminal, the actual composition condition of the preview image can be analyzed, the difference between the actual composition condition of the preview image and the standard composition condition is analyzed, and prompt information is output according to the difference, so that a shooting attitude of the terminal is adjusted by a shooting person according to the prompt information and/or the position of the shot object is adjusted by the shooting person according to the prompt information, and further the terminal can shoot a new preview image (the new preview image comprises the shot object) with a standard or near standard composition, then the user can input a shooting operation in the terminal, and when the terminal receives the shooting operation of the user, a target image can be generated according to the new preview image with a standard or near standard composition, so as to achieve the purpose that the preview image with a standard or near standard composition is shot by the terminal.

Specifically, referring to fig. 1, a flowchart of steps of a data processing method according to the present application is shown, where the method is applied to an electronic device, and the electronic device may include a terminal with a shooting function, such as a camera, a mobile phone, and a tablet computer. The method specifically comprises the following steps:

in step S101, a preview image including a subject is photographed in real time using an electronic device, and the photographed preview image including the subject is displayed in real time on a photographing interface of the electronic device.

In the method, when the electronic equipment is used for shooting the scene of the shot person, the user can control the electronic equipment to start the shooting function, and when the electronic equipment starts the shooting function, the electronic equipment can shoot the preview image containing the shot person in real time and display the shot preview image containing the shot person in real time on the shooting interface of the electronic equipment.

The shooting of the scene of the shot person by using the electronic equipment includes but is not limited to: a scene in which a subject is photographed or a scene in which a video is recorded using an electronic device, for example, a scene in which a photographer photographs a subject using an electronic device, or the like.

The electronic equipment is provided with a camera, a shot person is positioned in the shooting direction of the camera, and an image shot by the electronic equipment through the camera can be used as a preview image and displayed on a shooting interface of the electronic equipment in real time.

In one example, an electronic device captures an image stream through a camera and displays the captured image stream as a preview image stream on a capture interface of the electronic device in real time.

The preview image can be referred by a photographer, the preview image can not be a target image obtained by final shooting, the preview image is used for the photographer to refer to the content currently shot by the camera, and the preview image shot by the camera can be changed when the photographer changes the shooting posture of the electronic equipment.

Among others, in one embodiment, the size of the preview image displayed on the photographing interface may be the same as the size of the photographing interface. That is, the preview image is sufficiently filled in the display on the photographing interface.

The photographing interface may be located in at least a partial area of a screen of the electronic device, or the like.

In step S102, the actual position of the subject' S skeleton in the preview image is recognized using the skeleton position recognition model.

In one embodiment, the skeleton of the subject may include, but is not limited to: a plurality of skeletal key points in the skeleton of the subject.

The plurality of skeletal keypoints may include, but are not limited to: at least one key point of the head skeleton, at least one key point of the neck skeleton, at least one key point of the arm skeleton, at least one key point of the hand skeleton, at least one key point of the torso skeleton, at least one key point of the leg skeleton, and at least one key point of the foot skeleton, and the like.

In the present application, one of the ways of understanding the position of the skeleton in the image is: the relative position of each bone key point in the skeleton in the image.

The relative position of the bone key points in the image can be understood as: the ratio between "the position coordinates of the bone key points in the coordinate system corresponding to the image" and "the maximum position coordinates of the respective points in the image in the position coordinates in the coordinate system corresponding to the image".

For example, when the image is a rectangle, assuming that the origin of coordinates of the image is a point located at the lower left corner of the rectangle of the image, the maximum coordinates are position coordinates of a point located at the upper right corner of the image in the coordinate system corresponding to the image.

In this application, the skeleton position recognition model may be trained in advance, for example, a plurality of sample data is obtained, where each sample data includes: the image processing device comprises a sample image of a sample photographer and an annotation position of a skeleton of the sample photographer in the sample image. The model may then be trained using a plurality of sample data until parameters in the model converge, thereby yielding a skeleton location identification model.

The model comprises a convolutional neural network, a long-short term memory network or a cyclic neural network and the like.

In this way, in this step, the preview image may be input to the skeleton position recognition model, the actual position of the skeleton of the subject in the preview image may be obtained by processing the preview image with the skeleton position recognition model, and the actual position of the skeleton of the subject in the preview image may be output. In this way, the electronic device can obtain the actual position of the skeleton of the shot object in the preview image output by the skeleton position recognition model.

In step S103, the composition mode of the preview image is determined according to the actual position of the skeleton of the subject in the preview image and the composition mode classification model.

In the embodiment of the present application, in a scene in which a subject is photographed using an electronic device, there may actually exist a plurality of different composition modes, such as a golden section composition mode, a trisection composition mode, a triangle composition mode, a guideline composition mode, and the like.

In this application, the composition pattern classification model may be trained in advance, for example, a plurality of sample data is obtained, where each sample data includes: the position of the skeleton of the sample photographed person in the sample image and the labeling composition mode of the sample image. The model may then be trained using a plurality of sample data until parameters in the model converge, resulting in a composition pattern classification model.

In this way, in this step, the actual position of the frame of the subject in the preview image may be input to the composition pattern classification model, the composition pattern classification model may process the actual position of the frame of the subject in the preview image to obtain the composition pattern of the preview image, and the composition pattern of the preview image may be output. In this way, the electronic device can obtain the composition mode of the preview image output by the composition mode classification model.

In step S104, a standard position to which the skeleton of the subject is applied in the preview image in the composition mode is acquired.

One of the ways of understanding the standard position of the skeleton of the subject to be photographed that is applicable to the preview image in the composition mode may be: in the case where the position of the skeleton of the subject in the preview image of the composition mode is a standard position, the composition in the preview image of the composition mode is in accordance with aesthetic standards and is accepted and preferred by a wide range of users and photographers with professional knowledge.

In the case where the position of the skeleton of the subject in the captured image of the composition pattern is a standard position in the captured image of the composition pattern, the quality of the captured image of the composition pattern is often evaluated as high quality.

The steps can specifically refer to the embodiments shown later, and are not described in detail herein.

In step S105, in a case where the distance between the actual position and the standard position is greater than the preset distance threshold, displaying a first prompt message on the shooting interface, where the first prompt message is used to prompt: and reducing the distance between the actual position of the skeleton of the shot object in the preview image and the standard position to be less than or equal to a preset distance threshold value.

The method includes prompting a photographer to move or the photographer to change a shooting posture of the electronic device, and further enabling an actual position of a skeleton of the photographer in a preview image of the composition mode shot later in the preview image of the composition mode shot later to be close to or the same as (for example, smaller than or equal to a preset distance threshold value or the like) a standard position which is applicable to the skeleton of the photographer in the preview image of the composition mode shot later. In this way, a shooting operation can be input into the electronic device, and when the electronic device receives the shooting operation, a target image is generated according to a new preview image shot by the electronic device, wherein the distance between the actual position of the skeleton of the shot person in the new preview image in the composition mode and the standard position of the skeleton of the shot person in the new preview image is smaller than or equal to the preset distance threshold.

In one embodiment, the actual position of the skeleton of the photographed person in the preview image may include, but is not limited to: the actual positions of a plurality of skeletal key points in the skeleton of the subject in the preview image. The standard positions to which the skeleton of the subject is applied in the preview image of the composition mode may include, but are not limited to: and a plurality of skeleton key points in the skeleton of the shot object are applicable to the preview image of the composition mode.

The plurality of at least one keypoint of the bone may include, but is not limited to: at least one key point of the head skeleton, at least one key point of the neck skeleton, at least one key point of the arm skeleton, at least one key point of the hand skeleton, at least one key point of the torso skeleton, at least one key point of the leg skeleton, and at least one key point of the foot skeleton, and the like.

In this way, when calculating the distance between the actual position and the standard position, the euclidean distance between the actual position and the standard position may be calculated, for example, for any one of a plurality of skeletal key points in the skeleton of the subject, the euclidean distance between the actual position of the skeletal key point in the preview image and the standard position to which the skeletal key point is applied in the preview image of the composition mode may be calculated to obtain the euclidean distance corresponding to the skeletal key point, and the same may be applied to each of the other skeletal key points in the plurality of skeletal key points in the skeleton of the subject. Thereby obtaining the Euclidean distance corresponding to each bone key point in a plurality of bone key points in the skeleton of the shot person.

Then, an average value of euclidean distances corresponding to each of a plurality of bone key points in the skeleton of the subject may be calculated, so as to obtain a distance between the actual position and the standard position.

In the application, the electronic equipment is used for shooting the preview image containing the shot person in real time, and the shot preview image containing the shot person is displayed on a shooting interface of the electronic equipment in real time. The actual position of the subject's skeleton in the preview image is identified using a skeleton position recognition model. And determining the composition mode of the preview image according to the actual position of the skeleton of the shot in the preview image and the composition mode classification model. And acquiring a standard position which is applicable to the skeleton of the shot object in the preview image of the composition mode. Under the condition that the distance between the actual position and the standard position is greater than a preset distance threshold, displaying first prompt information on a shooting interface, wherein the first prompt information is used for prompting: and reducing the distance between the actual position of the skeleton of the shot object in the preview image and the standard position to be less than or equal to a preset distance threshold value. Through the method and the device, a user can be given a real-time composition suggestion under the condition that the user shoots the image, so that the user is assisted in shooting the image of which the composition is standard or close to the standard, the quality of the image shot by the user is improved, and the shooting experience of the user can be improved.

In one embodiment of the present application, referring to fig. 2, step S103 includes:

in step S201, a standard position, which is set in advance in the electronic apparatus, to which the skeleton of the subject is applied in the image of the composition mode is acquired.

For any composition mode, in a scene of shooting an image of the composition mode, in order to make the composition of the image of the composition mode standard or close to standard, a shot person in the image of the composition mode tends to apply at least one standard position in the image of the composition mode.

The example of applying a standard position to the image of the composition mode by the subject in the image of the composition mode is described, but the scope of the present application is not limited thereto.

A standard position to which the skeleton of the subject is applied in the image of the composition mode can be set in the electronic apparatus in advance.

In this way, in this step, the electronic device can directly acquire the standard position, which is set in advance in the electronic device and to which the skeleton of the subject is applied in the image of the composition mode.

In one embodiment, the photographer sets a standard position to which the skeleton of the subject is applied to the image in the composition mode in advance in the electronic device, the subject sets a standard position to which the skeleton of the subject is applied to the image in the composition mode in advance in the electronic device, and the subject of another character related to the electronic device sets a standard position to which the skeleton of the subject is applied to the image in the composition mode in advance in the electronic device. For this embodiment, reference may be made to the embodiments shown later, and details will not be given here.

In step S202, a standard position to which the skeleton of the subject is applied in the preview image of the composition mode is acquired from a standard position to which the skeleton of the subject is applied in the image of the composition mode, which is set in advance in the electronic apparatus.

In one embodiment of the present application, when the size of the "image" in the "standard position to which the skeleton of the subject is applied to the image in the composition mode, which is set in advance in the electronic device, is the same as the size of the preview image in the composition mode, the" standard position to which the skeleton of the subject is applied to the image in the composition mode ", which is set in advance in the electronic device, may be directly used as the standard position to which the skeleton of the subject is applied to the preview image in the composition mode.

Alternatively, in another embodiment of the present application, in a case where the size of the "image" in the "standard position to which the skeleton of the subject is applied in the image of the composition mode, which is set in advance in the electronic apparatus, is different from the size of the preview image of the composition mode, a ratio between the size of the preview image of the composition mode and the size of the" image "in the" standard position to which the skeleton of the subject is applied in the image of the composition mode, "which is set in advance in the electronic apparatus, may be calculated, and then the standard position to which the skeleton of the subject is applied in the preview image of the composition mode may be acquired based on the ratio and the" standard position to which the skeleton of the subject is applied in the image of the composition mode, "which is set in the electronic apparatus.

In the case of shooting using an electronic device, some objects are often involved, for example, a photographer, a subject of the photographer or other characters related to the electronic device, and the like.

In a possible case, the requirements of the subject of the photographer, the subject, or other characters related to the electronic device may change, for example, the requirements of the subject for the standard of composition (e.g., the aesthetic standard of composition, etc.) may change, so that the standard position to which the skeleton of the subject required by the subject is applied in the image of the composition mode may change.

For this reason, in the present application, a subject that supports a photographer, a subject, or another character related to an electronic device needs to be modified for "a standard position to which a skeleton of the subject is applied in an image of the composition mode".

In particular, it is possible to support modification of a standard position of the skeleton of the subject in the image of the composition mode in the electronic device in real time.

For example, a subject of a photographer, a subject, or other character related to the electronic device may input to the electronic device a modification operation for "a standard position to which a skeleton of the subject is applied in an image of the composition mode, which is set in the electronic device in advance".

The electronic device may receive the modification operation, and modify a standard position, which is set in the electronic device in advance and to which the skeleton of the subject is applied in the image of the composition mode, according to the modification operation.

In the present application, in the case of shooting with an electronic device, some objects, for example, a photographer, a subject, an environmental background where the subject is located, and the like, are often involved.

In one embodiment, the photographer may have his or her own requirement for "standard position for the subject's skeleton to be suitable in the image of the composition mode".

In the case where the photographer has a request for "the standard position to which the skeleton of the subject is applied in the image of the composition mode", in order to make the position of the skeleton of the subject in the image of the composition mode captured by the photographer using the electronic device in the captured image of the composition mode equal to or close to "the standard position to which the skeleton of the subject is applied in the image of the composition mode" requested by the photographer, the photographer may be supported to set "the standard position to which the skeleton of the subject is applied in the image of the composition mode" requested by the photographer in advance in the electronic device.

For example, the photographer inputs in advance "the standard position to which the skeleton of the subject is applied in the image of the composition mode" and the identification of the photographer, which are required by the photographer, in the electronic device, so that the electronic device can store the identification of the photographer and "the standard position to which the skeleton of the subject is applied in the image of the composition mode" required by the photographer in the correspondence between the identification and the standard position.

In this way, when the standard position, which is set in the electronic device in advance and to which the skeleton of the subject is applied in the image of the composition mode, is acquired in step S201, the identification of the photographer who has registered in the electronic device can be acquired. Then, according to the identity of the photographer, a standard position of the photographer to which the skeleton of the photographer is applied in the image in the composition mode is obtained, for example, in a correspondence relationship between the identity and the standard position, a standard position corresponding to the identity of the photographer is searched for and is used as a standard position of the photographer to which the skeleton of the photographer is applied in the image in the composition mode, that is, a standard position of the photographer to which the skeleton of the photographer is applied in the image in the composition mode.

The identity of the photographer can be the name or the identification number of the photographer, and the identity of different photographers is different.

In another embodiment, the subject may have a requirement of the subject for "a standard position where the subject's skeleton is suitable in the image of the composition mode".

In the case where the subject has a request for "the standard position to which the subject's skeleton is applied in the image of the composition mode", in order to make the position of the subject's skeleton in the image of the composition mode captured by the electronic device by the subject in the captured image of the composition mode equal to or close to "the standard position to which the subject's skeleton is applied in the image of the composition mode" requested by the subject, the subject may be supported to set "the standard position to which the subject's skeleton is applied in the image of the composition mode" requested by the subject in the electronic device in advance.

For example, the electronic device may store the identification of the subject and the "standard position to which the skeleton of the subject is applied in the image of the composition mode" required by the subject in the correspondence between the identification and the standard position, in which the skeleton of the subject is applied in the image of the composition mode.

In this way, when the standard position, which is set in the electronic apparatus in advance and to which the skeleton of the subject is applied in the image of the composition mode, is acquired in step S201, the identification of the subject in the preview image can be recognized (the facial features of the subject in the preview image can be recognized using a face recognition technique, and then the identification of the subject is acquired from the facial features of the subject). Then, a standard position of the subject to which the skeleton of the subject is applied in the image in the composition mode is obtained according to the identity of the subject, for example, in a correspondence relationship between the identity and the standard position, a standard position corresponding to the identity of the subject is searched for and is used as a standard position of the subject to which the skeleton of the subject is applied in the image in the composition mode, that is, a standard position of the subject to which the skeleton of the subject is applied in the image in the composition mode.

The identification of the photographed person may be the name or identification number of the photographed person, and the identification of different photographed persons is different.

In another embodiment, there may be different requirements for the "standard position of the frame of the subject in the different environment background images in the composition mode" for different environment backgrounds, that is, the standard position of the frame of the subject in the image in the composition mode is different in different environment backgrounds.

The environmental context may include buildings, parks, roads, rivers, oceans, sky, and mountains, among others.

In order to enable the composition of various environment background images to be more reasonable, the composition is more adaptive to the corresponding environment background, the composition aesthetics of the images is improved, and the quality of the shot images is further improved.

It is possible to support setting in advance in the electronic device standard positions for which the skeleton of the subject is suitable in the image of the composition mode for various possible environmental backgrounds, respectively.

For example, for any one of the environment backgrounds that may exist, the "standard position for the environment background to which the skeleton of the subject is applied in the image in the composition mode" and the environment background may be input in advance in the electronic apparatus, so that the electronic apparatus may store the environment background and the "standard position for the environment background to which the skeleton of the subject is applied in the image in the composition mode" in the correspondence between the environment background and the standard position. The same is true for every other environmental context that may exist.

In this way, when the standard position, which is set in advance in the electronic apparatus and to which the skeleton of the subject is applied in the image of the composition mode, is acquired in step S201, the environmental background in which the subject is located in the preview image can be recognized. Then, a standard position of the environment background for which the skeleton of the subject is applicable in the image of the composition mode is obtained, for example, in a correspondence between the environment background and the standard position, a standard position corresponding to the environment background is searched for and is used as a standard position of the environment background for which the skeleton of the subject is applicable in the image of the composition mode, that is, a standard position of the skeleton of the subject is applicable in the image of the environment background of the composition mode.

Further, after step S105, the photographer may input a shooting operation to the electronic device according to actual conditions to cause the electronic device to generate a target image from the preview image.

Wherein the size of the target image and the size of the preview image may be the same. And the composition mode of the target image and the composition mode of the preview image may be the same.

In a possible case, the actual position of the skeleton of the photographed person in the target image in the composition mode is the same as the standard position of the skeleton of the photographed person in the target image in the composition mode, in this case, the photographer and/or the photographed person actually adopts the recommendation of the electronic device, and the photographer and/or the photographed person agree with the "standard position of the skeleton of the photographed person in the image in the composition mode", thereby stating that the "standard position of the skeleton of the photographed person in the image in the composition mode" meets the requirements of the photographer and/or the photographed person.

However, in another possible case, there is a difference between the actual position of the skeleton of the subject in the target image of the composition mode "and the" standard position of the skeleton of the subject in the target image of the composition mode applicable in the target image of the composition mode ", in which case, the recommendation of the electronic device is not actually adopted by the photographer and/or the subject, and the" standard position of the skeleton of the subject applicable in the image of the composition mode "is not completely recognized by the photographer, thereby explaining that the" standard position of the skeleton of the subject applicable in the image of the composition mode "does not completely meet the needs of the photographer and/or the subject.

There is a difference between "the position where the subject's skeleton is applied in the image of the composition mode" actually required by the photographer and/or subject and "the standard position where the subject's skeleton is applied in the image of the composition mode".

In this case, in order to assist the photographer and/or the subject in capturing the image in the composition mode to have a position close to or equal to the "position to which the skeleton of the subject is applied in the image in the composition mode" actually required by the photographer and/or the subject when the image in the composition mode is captured later, so that the composition condition of the captured image is closer to the requirement of the subject on the composition.

Therefore, under the condition that the photographer and/or the photographed person take the image, the real-time composition suggestion can be given to the photographer and/or the photographed person according to the 'position of the skeleton of the photographed person suitable for the image in the composition mode' actually required by the photographer and/or the photographed person so as to carry out auxiliary shooting on the photographer and/or the photographed person, so that the personalized requirements of the photographer and/or the photographed person are met as much as possible, and the personalized shooting habits, personalized styles and the like of the photographer and/or the photographed person are met.

In addition, the position of the skeleton of the photographed person applied to the image in the composition mode, which is actually required by a large number of users, may also be changed, and thus, in order to comply with the changing actual requirement of the large number of users on the position of the skeleton of the photographed person applied to the image in the composition mode, in the present application, the target position may be uploaded to the server, so that the server may generate a new standard position of the skeleton of the photographed person applied to the image in the composition mode according to the target position of the skeleton of the photographed person in the target image in the composition mode, which is respectively generated and uploaded by the electronic devices of a plurality of photographed persons, in the target image in the composition mode, which is generated by the server. For example, the average position of the target position of the skeleton of the subject in each generated target image is calculated as a new standard position.

The electronic equipment can send second prompt information to the server, the electronic equipment can receive the second prompt information sent by the server, and the second prompt information is used for prompting whether a new standard position needs to be used for replacing a standard position which is set in the electronic equipment in advance and is suitable for the skeleton of the shot person in the image of the composition mode. In the case where the electronic device receives a confirmation operation for the second prompt message, a new standard location may be downloaded from the server. The new standard position is used to replace a standard position, which is set in the electronic device in advance and to which the skeleton of the subject is applied in the image of the composition mode.

So that auxiliary shooting can be carried out according to the position of the skeleton of the shot person in the image of the composition mode actually required by the shot person and/or the shot person, and the requirement of the shot person and/or the shot person on standard composition is met as much as possible.

In one embodiment, the actual position of the skeleton of the photographed person in the preview image may include, but is not limited to: the actual positions of a plurality of skeletal key points in the skeleton of the subject in the preview image. The plurality of at least one keypoint of the bone may include, but is not limited to: at least one key point of the head skeleton, at least one key point of the neck skeleton, at least one key point of the arm skeleton, at least one key point of the hand skeleton, at least one key point of the torso skeleton, at least one key point of the leg skeleton, and at least one key point of the foot skeleton, and the like.

Thus, in one embodiment of the present application, referring to fig. 3, step S105 includes:

in step S301, a human body frame of the subject is generated from actual positions of a plurality of skeletal key points in the skeleton of the subject in the preview image.

In step S302, an interface standard position corresponding to a standard position to which the skeleton of the subject is applied in the preview image in the composition mode is specified on the imaging interface.

In an embodiment of the present application, when the size of the preview image of the composition mode is the same as the size of the shooting interface of the electronic device, the standard position to which the skeleton of the photographer is applied in the preview image of the composition mode may be directly used as the interface standard position on the shooting interface.

Or, in another embodiment of the present application, in a case that the size of the preview image of the composition mode is different from the size of the capture interface of the electronic device, a ratio between the size of the capture interface of the electronic device and the size of the preview image of the composition mode may be calculated, and then the interface standard position "is obtained according to the ratio and the standard position to which the skeleton of the subject is applied in the preview image of the composition mode.

In step S303, a human body frame is displayed superimposed at an interface standard position on the shooting interface.

In the application, the human body frame displayed on the shooting interface and the preview image displayed on the shooting interface can be decoupled, the human body frame displayed on the shooting interface and the preview image displayed on the shooting interface can be located at different display levels, and the human body frame can be displayed on the preview image in a floating manner. The human body frame may not change position or disappear as the preview image changes or disappears.

In step S304, superimposition instruction information for prompting superimposition of a portrait of the subject in the preview image with a human body frame displayed on the photographing interface is displayed on the photographing interface.

In one example, the coincidence indication information may include an indication arrow or the like, and the indication arrow may point from "an actual interface position corresponding to an actual position of the skeleton of the subject in the preview image on the shooting interface" to the standard interface position to prompt the subject to move or the shooting posture of the electronic device to be changed by the shooting person.

The shooting posture of the electronic device can be conveniently changed by the shooting of the photographer or the shooting posture of the electronic device can be changed by the shooting posture prompting in a human body frame mode, so that the actual position of the skeleton of the photographer in the preview image of the composition mode shot later in the preview image of the composition mode is close to or the same as (for example, smaller than or equal to a preset distance threshold value and the like) the standard position applicable to the preview image of the composition mode shot later in the preview image of the composition mode, that is, the interface actual position corresponding to the actual position of the skeleton of the photographer in the preview image of the composition mode shot later in the shooting interface is close to or the same as the interface standard position corresponding to the standard position applicable to the preview image of the photographer in the preview image of the composition mode shot later in the shooting interface.
