In order to achieve the technical purpose, the embodiment of the application adopts the following technical scheme:

in a first aspect, an embodiment of the present application provides a photographing display method, which is applied to an electronic device including a first display screen, a second display screen, and a first camera, where the first display screen and the first camera are oriented in the same direction, and the first display screen and the second display screen are arranged in a back-to-back manner, and the method includes: the method comprises the steps that a first camera collects a preview image, and the preview image is displayed in a first preview interface of a first display screen; then, displaying the first multimedia content to be selected; then detecting a first operation of the user on the first to-be-selected multimedia content; and responding to the first operation, and displaying the first to-be-selected multimedia content on the first preview interface.

The object features of the first to-be-selected multimedia content and the object features of the preview image both comprise first object features. The first object features are used for characterizing the content of the preview image, and the object features comprise at least one of the following: character features and scene features.

It can be understood that, during the shooting of the shot person by the first camera, the electronic equipment displays the first to-be-selected multimedia content on the first display screen towards the shot person. The object features of the first to-be-selected multimedia content comprise first object features, and the first object features represent the content of the preview image. That is, the first candidate multimedia content includes content similar to the preview image. And because the preview image comprises the current shooting scene, the first to-be-selected multimedia content comprises the content similar to the preview image, which means that the first to-be-selected multimedia content comprises the content similar to the current shooting scene, and the first to-be-selected multimedia content has a certain reference value for the shot person. Furthermore, the shot person can refer to the first to-be-selected multimedia content while shooting to adjust the shot person to the best state and then shoot. Therefore, the process that the photographer repeatedly checks the first to-be-selected multimedia content and shoots the first to-be-selected multimedia content is avoided, the user operation is simplified, and the shooting experience of the user is improved.

In a possible design manner of the first aspect, before the displaying the first to-be-selected multimedia content, the method further includes: extracting object features of the preview image; acquiring a plurality of reference multimedia contents, and determining the object characteristics of each reference multimedia content in the plurality of reference multimedia contents; determining similarity between the object features of each reference multimedia content and the object features of the preview image; and determining that the at least one to-be-selected multimedia content comprises a reference multimedia content with the similarity larger than a preset similarity threshold, wherein the at least one to-be-selected multimedia content comprises a first to-be-selected multimedia content. The reference multimedia contents are locally stored multimedia contents for reference of photographing or multimedia contents acquired from a server for reference of photographing.

It can be understood that the electronic device determines that the reference multimedia content with the similarity greater than the preset similarity threshold is at least one candidate multimedia content from the plurality of reference multimedia contents. The similarity is a similarity between an object feature of one reference multimedia content and an object feature of the preview image, and the object feature may include a character feature and a scene feature. Then, the similarity is greater than a preset similarity threshold, which indicates that there is a similar character feature or scene feature between the reference multimedia content and the preview image. And because the preview image reflects the current framing content, the reference multimedia content is similar to the character feature or the scene feature in the current framing content, and has a higher reference value for the shot receiver. Furthermore, at least one to-be-selected multimedia content with the similarity larger than the preset similarity threshold determined by the electronic device has a larger reference value. The electronic equipment provides at least one piece of multimedia content to be selected for the user to select, and the first multimedia content to be selected, which is selected by the user from the at least one piece of multimedia content to be selected, also has a relatively high reference value.

In another possible design manner of the first aspect, the method further includes: under the condition that a second operation on the local multimedia content input by the user on the first display screen is detected, controlling the first display screen to jump from the first preview interface to the local multimedia interface; the local multimedia interface includes at least one local multimedia content different from the plurality of reference multimedia contents; detecting a third operation input by a user on the first display screen and aiming at least one local multimedia content; and responding to the third operation, determining that the at least one to-be-selected multimedia content further comprises the local multimedia content selected by the third operation, and controlling the first display screen to jump from the local multimedia interface to the first preview interface.

It is understood that, in addition to determining the first to-be-selected multimedia content according to the object features of the preview image, the electronic device may detect a third operation on the local multimedia content input by the user on the first display screen. The electronic equipment adds the local multimedia content selected by the third operation into at least one to-be-selected multimedia content, and any local multimedia content in the at least one to-be-selected multimedia content can be used as the first to-be-selected multimedia content and displayed on the first shooting interface. Therefore, the user can manually add local multimedia contents which need to be referred to and carry out reference in the shooting process.

In another possible design manner of the first aspect, the method further includes: and displaying at least one to-be-selected multimedia content on the first preview interface. The detecting of the first operation of the user on the first to-be-selected multimedia content includes: a first operation input by a user on the first display screen is detected.

In another possible design manner of the first aspect, the displaying at least one candidate multimedia content on the first preview interface includes: and displaying at least one to-be-selected multimedia content in the first preview interface according to the similarity between the first preview interface and the object features of the preview image.

It can be understood that, according to the above analysis, it is known that "at least one candidate multimedia content having a similarity greater than a preset similarity threshold determined by the electronic device has a greater reference value", and the greater the similarity, the greater the reference value provided by the candidate multimedia content to the shot multimedia content is. Therefore, the electronic device may display the at least one candidate multimedia content in the order of the similarity, for example, display the at least one candidate multimedia content in the order of the similarity from large to small, and then allow the user to preferentially select the one candidate multimedia content with a higher reference value as the first candidate multimedia content.

In another possible design manner of the first aspect, before the displaying the first to-be-selected multimedia content, the method further includes: extracting object features of the preview image; and if the object characteristics of the preview image meet the preset video reference requirement, determining at least one to-be-selected multimedia content as at least one reference video, wherein the at least one to-be-selected multimedia content comprises a first to-be-selected multimedia content. At least one reference video is a video which is locally stored and used for reference of photographing or a video which is acquired from a storage server and used for reference of photographing; the preset video reference requirement includes that the object feature of the preview image includes age information, and the age information belongs to target age information.

It is understood that, in order to be able to attract the attention of the photographer towards the first camera for taking the image, the plurality of reference multimedia contents may include a reference video that is able to attract the attention of the photographer. Furthermore, the first multimedia content to be selected can be any reference video, and the reference video is displayed on the first display screen, so that the attention of the photographed person can be attracted, and the photographed person can face the first display screen. And the first camera is faced to the first display screen, so that the image comprising the front face of the shot person can be shot by the first camera.

For example, by the fact that the subject who needs to attract attention may be a child, the target age information in the preset video reference requirement may be a child. The electronic device may provide at least one reference video capable of attracting attention of a child when the object features of the preview image include the child, and allow the user to select one of the reference videos to be displayed on the first preview interface. The reference video can attract the attention of the child, so that the child faces the first camera. At this time, the first camera can shoot images including the front face of the child.

In another possible design manner of the first aspect, after the first to-be-selected multimedia content is displayed on the first preview interface, the method further includes: under the condition that the first to-be-selected multimedia content is a first image, extracting an image outline of the first image, and displaying the image outline by adopting a preset first display effect on a first preview interface; under the condition that a fourth operation of the user on the image contour is detected, the image contour is adjusted, and the adjusted image contour is displayed on a first preview interface; a fourth operation for triggering an adjustment of at least one of a size and a position of the image contour; and under the condition that the fifth operation of the user on the first display effect is detected, updating the first display effect, and displaying the image contour by adopting the updated first display effect on the first preview interface.

It is understood that, in order to provide a better reference effect, the electronic device may extract an image contour of the first multimedia content to be selected and display the image contour. The image outline can provide reference for the shot person, and can reduce the shielding of the preview image displayed on the first preview interface. In this way, the photographer can see the framing effect through the first display screen and can refer to the image outline. Therefore, the shot person can adjust the self to the best state to shoot by combining the framing effect and the image contour. The shot image can better meet the requirements of the shot person, and the satisfaction degree of the shot person is improved.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

The embodiment of the application provides a photographing display method which can be applied to electronic equipment comprising a first display screen and a first camera. Wherein, the orientation of first display screen and first camera is the same. The first camera may refer to a camera used for shooting a subject in the electronic device. Then, the first display screen, which is oriented in the same direction as the first camera, is also oriented toward the subject.

The photographing display method provided by the embodiment of the application can be applied to a self-photographing scene (namely, a photographed person and a photographer are the same object) and a photographing scene (namely, the photographed person and the photographer are different objects).

In a self-timer scenario, the electronic device may include a display screen (e.g., the first display screen mentioned in this embodiment of the application). Of course, in practical applications, the electronic device may further include other display screens, such as a second display screen opposite to the first display screen, and a third display screen connected to the folding edge of the first display screen (in this case, the electronic device is an electronic device including a foldable display screen).

In his shooting scenario, the electronic device may include at least two display screens. The at least two display screens may include a first display screen and a second display screen opposite the first display screen; the electronic device may be a foldable screen or a non-foldable screen, such as a curved screen. Of course, in practical applications, the electronic device may further include other display screens, such as a third display screen connected to the folded edge of the first display screen.

Among them, the at least two display screens in the electronic device may be at least two display screens (which may be simply referred to as folding screens) that are foldable (e.g., a screen and B screen shown in (B) of fig. 1A, a1 screen and a2 screen shown in (c) of fig. 1B), or at least two display screens that are not foldable (e.g., a screen and B screen shown in fig. 2). The foldable screen may be folded to form at least two display screens, for example, the foldable screen may be folded along a folding edge or a folding axis to form a first display screen and a second display screen that are opposite to each other. The at least two non-foldable display screens may include a first display screen and a second display screen that are always opposite each other in the electronic device.

The folding screens in the embodiments of the present application can be classified into two types. The foldable screens folded outwards (called as outwards folded screens for short) and the foldable screens folded inwards (called as inwards folded screens for short) are adopted as one type of the foldable screens. For example, the foldable screen may be folded to form the first display screen and the second display screen. The first display screen and the second display screen are back to back after the folding screen is folded. After the inward folding screen is completely unfolded, the first display screen and the second display screen are opposite to each other.

For example, please refer to fig. 1A, which shows a product configuration diagram of an electronic device 100 with a folding screen according to an embodiment of the present application. Fig. 1A is a schematic view of the folded-out screen in a fully unfolded state. The folded-out screen may be folded along the folded edges in the directions 102a and 102B as shown in fig. 1A (a), to form a and B screens as shown in fig. 1A (B). The folded-out screen can be folded along the folding edges in the

directions

103a and 103b shown in fig. 1A (b), and can be folded into the folded-out screen shown in fig. 1A (c). As shown in fig. 1A (c), when the foldable screen of the electronic device 100 is completely folded, the a screen and the B screen are opposite to each other and visible to the user.

The orientation of the screen a is the same as that of the camera 101a, and the orientation of the screen B is the same as that of the camera 101B.

It is understood that for an electronic device having a fold-out folding screen, the interface may be displayed on screen a, on screen B, or on both screen a and screen B when the folding screen is in the folded state. When the folding screen is in the unfolding state, interfaces can be displayed on the A screen and the B screen. For the description of the unfolding state and the folding state of the folding screen, reference may be made to the description in the following embodiments, which are not repeated herein.

It should be noted that, an electronic device having at least two non-foldable display screens provided in the embodiments of the present application may refer to the electronic device 100 shown in fig. 1A (c). Unlike the electronic apparatus 100, the electronic apparatus having at least two display screens that are not foldable does not have a folding edge, which includes a screen a and a screen B facing each other.

For another example, please refer to fig. 1B, which shows a product form diagram of an electronic device 100 with a foldable screen folded inwards according to an embodiment of the present application. Fig. 1B (a) is a schematic view of the fully unfolded folded-in screen. When the fold-in folding screen is fully unfolded, an a-screen of the electronic device 100 may be formed. As shown in fig. 1B (B), a B screen may be provided on the back of the a screen.

The orientation of the screen A is the same as that of the camera 201a, and the orientation of the screen B is the same as that of the camera 201B.

The fold-in screen may be folded along the folded edges in the directions 202a and 202B shown in fig. 1B (a), to form the fold-in screen shown in fig. 1B (c). The flap-in screen can be folded along the folding edge in the directions 203a and 203B as shown in fig. 1B (c), and can be folded into the folded state as shown in fig. 1B (d). As shown in fig. 1B (d), when the folded-in folding screen is completely folded, the two folded parts of the a-screen are opposite to each other, and the black line 204 is a line on the contact surface of the two folded parts of the a-screen. After the folding screen is completely folded, the screen A is invisible to the user, and the screen B is visible to the user.

If the A screen consists of two display screens, namely an A1 screen and an A2 screen, the A1 screen and the A2 screen shown in (c) of FIG. 1B can be formed after the folded-in folding screen is folded. As shown in fig. 1B (d), when the fold-in screen is completely folded, the a1 screen and the a2 screen are opposite to each other, and the black line 204 is a line on the contact surfaces of the a1 screen and the a2 screen.

It is understood that for an electronic device having such a folding screen folded inwards, when the folding screen is in a folded state, an interface can be displayed on the B screen; when the folding screen is in the unfolding state, interfaces can be displayed on the A screen and the B screen.

Generally, the folding angle α of the folding screen (including the inward folding screen and the outward folding screen) is in the range of [0 °, 180 ° ]. And the folding included angle of the folded screen is the included angle between the screen A and the screen B. The folding angle of the folded-in folding screen is the angle between the A1 screen and the A2 screen. In the embodiment of the application, if α [0 °, P ], the electronic device may determine that the foldable screen is in the folded state; if α (P, 180 ° ], the electronic device may determine that the folding screen is in the unfolded state, or, if α [0 °, P), the electronic device may determine that the folding screen is in the folded state; if α [ P, 180 ° ], the electronic device can determine that the folding screen is in the unfolded state. Where P is a preset angle threshold. P can be determined according to the use habits of a large number of users using the folding screen; alternatively, P may be set in the electronic device by the user.

In some embodiments, according to the usage habit of most users, when the folding angle α is larger than 90 °, the possibility that the user wants to use the display screen located at both sides of the folding edge as a whole (i.e. as a complete display screen) is high. Therefore, the preset angle threshold P in the embodiment of the present application may be greater than 90 °. The value range of the preset angle threshold P may be (90 °, 180 °). For example, the preset angle threshold P may be 100 °, 120 °, 135 °, 140 °, 145 °, 150 °, or the like.

It should be noted that, at least two screens formed by folding the folding screens (including the inward folding screen and the outward folding screen) in the embodiment of the present application may be a plurality of screens (for example, the a screen and the B screen shown in (c) in fig. 1A) that are independent from each other, or may be one complete screen (for example, the a screen shown in (a) in fig. 1B) that is an integral structure, and only is folded to form at least two parts.

For example, the folded screen may be a flexible folded screen. The flexible folding screen comprises a folding edge made of flexible materials. Part or all of the flexible folding screen is made of flexible materials. At least two screens formed by folding the flexible folding screen are a whole screen of an integral structure, and only the flexible folding screen is folded to form at least two parts.

For another example, the folding screen may be a multi-screen folding screen. The multi-screen folding screen may include a plurality (two or more) of screens. The plurality of screens are a plurality of individual display screens. The plurality of screens may be connected in turn by a folding shaft. Each screen can rotate around a folding shaft connected with the screen, and folding of the multi-screen folding screen is achieved.

In fig. 1A and 1B, the foldable screen in the embodiment of the present application is described by taking the foldable screen as an example. In addition, in the following embodiments of the present application, the method provided in the embodiments of the present application is also described by taking the foldable screen as a flexible foldable screen as an example.

For example, please refer to fig. 2, which illustrates an electronic device with at least two non-foldable display screens provided in an embodiment of the present application. Fig. 2 (a) is an a-screen of the electronic device 100, and the a-screen includes a camera 210 a. Fig. 2 (B) is a B screen of the electronic apparatus 100, which includes the camera 210B. Fig. 2 (c) is a side view of the electronic apparatus 100, and a B screen is opposite to the a screen. As can be seen from (c) of fig. 2, there is no folding edge between the a screen and the B screen of the electronic apparatus 100, and the electronic apparatus 100 does not have a folding function.

It should be noted that the a screen in the electronic device 100 may be a first display screen, and the B screen is a second display screen. Alternatively, if the B screen in the electronic device 100 is the first display screen, the a screen is the second display screen. The camera in the first display screen may be referred to as a first camera and the camera in the second display screen may be referred to as a second camera.

Currently, when a photographer takes a picture of a person to be photographed by using a first camera in an electronic device, after controlling the first camera to start, and before the first camera starts to photograph, a preview image (which may also be referred to as a viewfinder image) collected by the first camera may be displayed on a first display screen in real time. The first display screen faces the shot person, and the shot person can view the preview image including the shot person through the first display screen. Further, a more satisfactory image is taken from the viewed preview image.

The preview image refers to an image acquired before shooting after the first camera starts working.

For example, taking the electronic device 100 shown in fig. 1B as an example, the B screen in the electronic device 100 may be a first display screen, and the a screen may be a second display screen. The camera 201B included in the B screen is the first camera. The second display screen is a complete screen of unitary construction. When the photographer uses the first camera 201b to perform his shooting, the preview image captured by the first camera 201b is displayed in real time on the second display screen after the first camera 201b is started. As shown in fig. 3 (a), the electronic apparatus 100 also displays a switch option 301 on the second display screen. The switch option 301 is used to trigger the electronic device 100 to synchronously display the preview image in the first display screen. When the switch option 301 is in the ON state (ON), the electronic apparatus displays a preview image captured by the first camera 201b ON the first display screen in real time, as shown in (b) of fig. 3.

Although the preview image captured by the first camera is displayed in real time on the first display screen facing the photographed person, in the case of photographing after some images which can be referred to need to be viewed, the preview image captured in real time is displayed to the photographed person only through the first display screen, and the photographed person still needs to finish photographing by virtue of the impression of the photographed person on the images. The images thus taken may still be significantly different from the effects of these referenceable images. The photographed person needs to review these images for reference and then photograph the images. In this way, the user needs to repeat the operation to capture a satisfactory image, resulting in a poor photographing experience of the subject.

In order to solve the problem of poor photographing experience caused by the fact that a user needs to repeatedly check a reference image and shoot the reference image, the embodiment of the application provides a photographing display method. Therefore, the shot person can refer to the first to-be-selected multimedia content while shooting so as to adjust the shot person to the best state and then shoot. Therefore, the first multimedia content to be selected is displayed for reference to the shot person in the shooting process, so that the process that the user repeatedly checks the image which can be referred to and shoots the image is avoided, the user operation is simplified, and the shooting experience of the user is improved.

The plurality of reference multimedia contents acquired by the electronic equipment can be marked with object characteristics. Or, if the plurality of reference multimedia contents acquired by the electronic device do not have the object feature, the electronic device extracts the object feature from the plurality of reference multimedia contents respectively.

The electronic device may then determine that the at least one candidate multimedia content includes reference multimedia content having object features similar to the object features of the preview image.

Or, the electronic device may further acquire real-time location information of the electronic device through positioning technologies such as GPS, BDS, or SBAS. The electronic device takes the real-time location information as location information in the object feature of the preview image. The electronic device then determines that the at least one candidate multimedia content includes a reference multimedia content having object features similar to the object features of the preview image.

In some embodiments, the similarity of the object feature of the reference multimedia content and the object feature of the preview image may mean that the first object feature is the same between the object feature of the reference multimedia content and the object feature of the preview image, for example, the number of persons in the object feature of the reference multimedia content is the same as the number of persons in the object feature of the preview image.

In some embodiments, the electronic device may determine a similarity between the object feature of each reference multimedia content and the object feature of the preview image (i.e., a similarity corresponding to each reference multimedia content), and further determine a plurality of similarities corresponding to the plurality of reference multimedia contents. Then, the electronic device determines that the at least one candidate multimedia content includes a reference multimedia content with a corresponding similarity greater than a preset similarity threshold.

The similarity corresponding to any one of the reference multimedia contents may be equal to the number of the same features between the object feature of the preview image and the object feature of the reference multimedia content. The preset similarity threshold may be a positive integer greater than 0.

Illustratively, the object features of the preview image include: the number of persons is 1 person, the sex of the person is female, the location information is building a, the time information is day time, and the environment type is outdoor. The object characteristics of any one of the reference multimedia contents are: the number of persons is 1 person, the sex of the person is a woman, the location information is building a, and the time information is night. The similarity between the object features of the preview image and the object features of the reference multimedia content is 3.

Wherein the first candidate multimedia content may be one of the at least one candidate multimedia content. The shot person adjusts itself by referring to the first to-be-selected multimedia content on the first preview interface so as to make itself in a better state. Then, an image is captured by the first camera. The shot image can better meet the requirements of the shot person.

In the embodiment of the application, after the electronic device determines at least one multimedia content to be selected, the electronic device can display the at least one multimedia content to be selected on the first display screen under the condition that a photographer uses the first camera to perform self-shooting. Then, the electronic device can detect a triggering operation of a first to-be-selected multimedia content in the at least one to-be-selected multimedia content input by a user on the first display screen, and display the first to-be-selected multimedia content in the first preview interface.

Or, in the case that the photographer performs his photographing with the first camera and the electronic device includes the second display screen, the at least one multimedia content to be selected may be displayed on the first display screen or the second display screen. Then, the electronic device may detect a triggering operation of the first to-be-selected multimedia content input by the user on the first display screen or the second display screen, and display the first to-be-selected multimedia content in the first preview interface. The electronic device may also display or not display the first to-be-selected multimedia content on the second preview interface.

The triggering operation on the first to-be-selected multimedia content may be a clicking operation, a sliding operation or a dragging operation on the first to-be-selected multimedia content.

The electronic equipment can display at least one to-be-selected multimedia content on the first display screen or the second display screen according to the size sequence of the similarity between the electronic equipment and the object features of the preview image. That is to say, the at least one to-be-selected multimedia content displayed on the first display screen or the second display screen is the at least one to-be-selected multimedia content sorted according to the size sequence of the similarity.

The electronic device 100 detects a dragging operation of a certain image 715 to be selected in the preset multimedia window 714, which is input by a user on the first display screen. Wherein, the dragging operation on the candidate image 715 is a triggering operation on the first candidate multimedia content. The candidate image 715 is the first image. As shown in fig. 7 (c), in response to a trigger operation, the electronic device 100 displays a first image 715 on the first preview interface 710 and hides a preset multimedia window 714.

As can be seen from (c) in fig. 7, since the electronic device 100 extracts the object feature of the preview image, it includes: female, Beijing Oracle, one person. Thus, the object features of first image 715 may also include: female, Beijing Oracle, one person.

Illustratively, taking the at least one candidate multimedia content as the at least one candidate image as an example, for the second preview interface 820 shown in fig. 8 (c), the second preview interface 820 includes a preset multimedia window 823, and the preset multimedia window 823 includes at least one candidate image after sorting. The electronic device 100 detects a click operation on a certain image 824 to be selected in the preset multimedia window 823, which is input by the user on the second display screen. Wherein, the click operation on the image to be selected 824 is a trigger operation on the first multimedia content to be selected. The candidate image 824 is the first image. As shown in (d) of fig. 8, the electronic device 100 displays a first image 824 on the first preview interface 810 in response to a trigger operation. Meanwhile, as shown in (e) of fig. 8, the electronic apparatus 100 may further display a first image 824 on the second preview interface 820 and hide the preset multimedia window 823.

As can be seen from (d) in fig. 8, since the electronic device 100 extracts the object feature of the preview image, it includes: female, Beijing Oracle, one person. In this regard, the object features of the first image 824 may also include: female, Beijing Oracle, one person.

It can be understood that, during the shooting of the shot person by the first camera, the electronic equipment displays the first to-be-selected multimedia content on the first display screen towards the shot person. The object features of the first to-be-selected multimedia content comprise first object features, and the first object features represent the content of the preview image. That is, the first candidate multimedia content includes content similar to the preview image. And because the preview image comprises the current shooting scene, the first to-be-selected multimedia content comprises the content similar to the preview image, which means that the first to-be-selected multimedia content comprises the content similar to the current shooting scene, and the first to-be-selected multimedia content has a certain reference value for the shot person. Furthermore, the shot person can refer to the first to-be-selected multimedia content while shooting so as to adjust the shot person to the best state and then shoot. Therefore, the process that the photographer repeatedly checks the first to-be-selected multimedia content and shoots the first to-be-selected multimedia content is avoided, the user operation is simplified, and the shooting experience of the user is improved.

In the embodiment of the present application, in order to be able to attract the attention of the photographer to face the first camera for photographing the image, the plurality of reference multimedia contents may include a reference video that is able to attract the attention of the photographer. Furthermore, the first multimedia content to be selected can be any reference video, and the reference video is displayed on the first display screen, so that the attention of the photographed person can be attracted.

Wherein the plurality of reference multimedia contents may include at least one reference video set for any type of the photographed persons who need to attract attention. The object features marked by the at least one reference video may include object features possessed by this type of photographer. For example, any type of subject who needs to attract attention may be a child, and the age information in the object feature marked by the at least one reference video is a child.

Specifically, after extracting the object features of the preview image, the electronic device determines that at least one to-be-selected multimedia content is at least one reference video if the object features of the preview image meet a preset video reference requirement; the at least one candidate multimedia content includes a first candidate multimedia content. At least one reference video is a video which is locally stored and used for reference of photographing or a video which is acquired from a storage server and used for reference of photographing; the preset video reference requirement includes that the object feature of the preview image includes age information, and the age information belongs to target age information.

Illustratively, taking the example that the subject who needs to attract attention is a child, the electronic device may acquire a plurality of reference multimedia contents in advance. The plurality of reference multimedia contents may include a plurality of reference images and a plurality of reference videos marked with children. The electronic device extracts object features for each reference image in the plurality of reference multimedia contents and marks the reference image with the extracted object features. The electronic device then stores a plurality of reference images tagged with the object features and a plurality of reference videos tagged with the child.

Further, if the object features of the preview image include a child, the electronic device may determine at least one candidate video from the plurality of reference videos marked with the child, for example, the at least one candidate video may be the plurality of reference videos marked with the child. The electronic device may then display the at least one video to be selected on the first preview interface or the second preview interface. At this time, the at least one candidate multimedia content is at least one candidate video.

If the object features of the preview image do not include the child, the electronic device may determine that at least one image to be selected includes a reference image with a similarity greater than a preset similarity threshold from the plurality of reference images marked with the object features. Then, the electronic equipment displays at least one image to be selected on the first preview interface or the second preview interface. At this time, the at least one candidate multimedia content is at least one candidate image.

For example, taking the electronic device 100 shown in (a) of fig. 1B as an example, if the photographer takes his/her photograph with the camera 201B in the electronic device 100, the B screen facing the same direction as the camera 201B is a first display screen facing the photographer, the camera 201B is a first camera, the a screen is a second display screen, and the camera 201a is a second camera. As shown in (a) of fig. 9, in the operating state of the first camera 201b, the electronic apparatus 100 displays a first preview interface 910 on the first display screen. As shown in (b) of fig. 9, the electronic apparatus 100 may further display a second preview interface 920 on the second display screen. The first preview interface 910 and the second preview interface 920 each include a preview image captured by the first camera 201 b. The second preview interface 920 may also include a conversion option 921, and a capture option 922.

Then, the electronic device 100 extracts the object features of one frame of preview image, and pops up a preset multimedia window 923 on the second preview interface 920. If the object features of the preview image include a child, the electronic device 100 determines that the plurality of reference videos marked with the child in the plurality of reference multimedia contents are at least one video to be selected according to the child in the object features of the preview image, and displays the at least one video to be selected in a preset multimedia window 923 in the second preview interface 920, as shown in (c) of fig. 9.

The electronic device 100 detects a click operation of a certain video 924 to be selected in the preset multimedia window 923, which is input by the user on the second display screen. Wherein, the click operation on the video to be selected 924 is a trigger operation on the first multimedia content to be selected. The candidate video 924 is the first video. As shown in (d) of fig. 9, the electronic device 100 displays a first video 924 on the first preview interface 910 in response to the trigger operation.

In the embodiment of the application, in order to provide a better reference effect, the electronic device may extract an image contour of the first multimedia content to be selected, and may further display the image contour with a more prominent display effect. Therefore, the shot person can see the image contour in the first multimedia content to be selected more clearly to shoot by referring to the image contour.

Specifically, as shown in fig. 10, the photographing display method provided in the embodiment of the present application may further include S1001 after S603. The method may further include S1002 or S1003 after S1001.

S1001, the electronic equipment extracts an image contour of the first to-be-selected multimedia content and displays the image contour on the first preview interface by adopting a preset first display effect.

Wherein the first display effect may include color, line thickness, and the like.

It should be noted that the electronic device may not display the first to-be-selected multimedia content on the first preview interface, and display the image contour by using a preset first display effect.

In the embodiment of the application, under the condition that the first to-be-selected multimedia content is the first image, the electronic equipment extracts the image contour of the first image to obtain an image contour. Under the condition that the first to-be-selected multimedia content is a first video, the electronic equipment extracts image outlines from a plurality of frame images included in the first video to obtain a plurality of image outlines corresponding to the plurality of frame images.

The electronic device may extract an image contour from the first image or one frame of image in the first video by using an image edge extraction method based on depth learning or an image contour extraction method based on depth learning. The image edge extraction method based on deep learning can comprise the following steps: integral-Nested Edge Detection (HED), depth-class-Aware Semantic Edge Detection (CASENT). The image contour extraction method based on the deep learning can comprise the following steps: a multi-scale bifurcation deep network deep, Full convolutional encoder-decoder (CEDN) suitable for top-down contour detection.

Further, the first image includes a person. The electronic equipment can extract the figure outline from the first image and display the figure outline by adopting a preset first display effect on the first preview interface.

It should be noted that the first image may include other objects such as a car and an animal in addition to the person, and the electronic device may further extract outlines of the other objects from the first image and display the outlines.

In the embodiment of the application, after the electronic device obtains the image contour, the electronic device can perform character positioning on a frame of preview image acquired at the current moment, and determine character position information in the frame of preview image. Then, the electronic equipment displays the image outline on the first preview interface according to the person position information.

The electronic equipment can determine a first size and a first position of the image outline in the first preview interface according to the person position information. Then, the electronic device may display the image contour on the first preview interface according to the first size and the first position, so that the image contour in the first preview interface and the region where the person is located in the preview image in the first preview interface are overlapped.

In the embodiment of the application, under the condition that a photographer takes a picture of the person by using the first camera and the electronic device comprises the second display screen, after the electronic device determines the position information of the person in a frame of preview image acquired at the current moment, the outline of the image can be displayed on the second preview interface according to the position information of the person.

The electronic device can determine a second size and a second position of the image outline in the second preview interface according to the person position information. Then, the electronic device may display the image contour on the second preview interface according to the second size and the second position, so that the image contour in the second preview interface and the region where the person is located in the preview image in the second preview interface coincide.

Further, the electronic device may further display the image outline at a second preview interface by using a preset second display effect. The second display effect and the first display effect may be the same or different.

As can be appreciated, the photographer mainly views the framing effect through the preview image in the second preview interface; therefore, compared with the first display effect, the image contour displayed by the second display effect is not prominent, and the interference of the image contour on the preview image displayed on the second preview interface is reduced. For example, the line thickness in the second display effect is thin and the color is light. The photographed person needs to refer to the image contour in the first preview interface, so the first display effect can make the image contour more prominent so that the photographed person can clearly see the image contour. For example, the line thickness in the first display effect is thick and the color is a dark color.

Illustratively, continuing with the example of electronic device 100 shown in fig. 8, after first preview interface 810 and second preview interface 820 display first image 824, electronic device 100 may extract an image outline for the first image and display a prompt on second preview interface 820 that the outline is being extracted. The electronic device 100 further performs character positioning on a frame of preview image acquired at the current time, and determines character position information in the frame of preview image.

Then, the electronic device 100 may determine a first size and a first position of the image outline in the first preview interface and a second size and a second position of the image outline in the second preview interface according to the person position information. As shown in fig. 11 (a), the electronic device 100 may display an image outline 1101 at the first preview interface 810 with a first display effect in a first size and a first position. As shown in fig. 11 (b), the electronic apparatus 100 further displays the image outline 1102 in the second preview interface 820 with the second display effect in the second size and the second position.

As can be seen from (a) and (b) in fig. 11, the image outline 1101 in the first preview interface coincides with the region where the person is located in the preview image in the first preview interface, and the image outline 1102 in the second preview interface coincides with the region where the person is located in the preview image in the second preview interface. The image outline 1101 is more prominent than the image outline 1102.
