Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

A method for taking photos of multiple people provided by an embodiment of the present invention can be performed by a terminal. In an embodiment of the present invention, the terminal is a device with a photographing and/or video recording function, such as a mobile phone, a tablet computer, a camera, and the like.

The technical solutions provided by various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a flow chart of a method for taking pictures of multiple people provided by an embodiment of the present invention. Referring to Fig. 1, the multi-person photographing method provided by the embodiment of the present invention may include:

Step 110 , in a state where M reference composition objects are displayed on the shooting preview interface, detecting shooting information of N shooting objects in the shooting preview interface.

Wherein, the shooting information includes at least one of shooting position and shooting posture; N is an integer greater than 1, and M is a positive integer.

In this embodiment of the present invention, the photographed object may be an object photographed by the terminal, and the object may be, for example, a user, an animal, and the like. Multi-subject may refer to multiple subjects (ie, two or more subjects). For example, if it is necessary to take a group photo of 3 people, each person is a subject, which may be subject A, subject B, subject C, and subject D in sequence.

In the embodiment of the present invention, the shooting preview interface may be an interface displayed in the viewfinder lens of the terminal.

In the embodiment of the present invention, the reference composition object may be a cartoon character or a schematic diagram of a character drawn by lines, so as to serve as a reference. For example, when taking a photo, it is used for position reference by the photographed subject. In addition, the reference composition object may have a photographing pose for the photographed subject to refer to the pose.

In this step, when the shooting information includes shooting positions, detecting the shooting information of the N shooting objects in the shooting preview interface is specifically detecting the shooting positions of the N shooting objects in the shooting preview interface. When the shooting information includes shooting postures, detecting the shooting information of the N shooting objects in the shooting preview interface is specifically detecting the shooting postures of the N shooting objects in the shooting preview interface. When the shooting information includes shooting positions and shooting postures, detecting the shooting information of the N shooting objects in the shooting preview interface is specifically detecting the shooting positions and shooting postures of the N shooting objects in the shooting preview interface.

The shooting position of the shooting object is the position of the subject image formed by the shooting object in the shooting preview interface.

Step 120, for each of the N shooting objects, if it is detected that the shooting information of the shooting object matches the shooting information of the corresponding reference composition object, acquire the corresponding intermediate image to get N intermediate images.

The matching of the shooting information of the shooting object with the shooting information of the corresponding reference composition object may indicate that the shooting position of the shooting object coincides with the position of the corresponding reference composition object, or that the shooting posture of the shooting object is consistent with the posture of the corresponding reference composition object. unanimous.

In the embodiment of the present invention, overlapping is a relative concept rather than an absolute concept. The coincidence of the shooting position of the shooting object in the shooting preview interface with the position of the reference composition object may indicate that the shooting position of the shooting object in the shooting preview interface mostly coincides with the position of the reference composition object, for example, greater than a preset percentage ( The preset percentage is generally greater than 50%, such as 70% or 80%, etc.). That is to say, in the present invention, the coincidence of the position of the shooting object in the shooting preview interface with the position of the reference composition object does not necessarily require 100% coincidence. Similarly, consistent posture does not necessarily require 100% consistency.

In the process of detecting whether the shooting posture matches, the contour of the photographed object can be firstly matched with the contour of the corresponding reference composition object. Match the shooting pose of the subject in the composition. Among them, the contour matching can adopt a related image recognition method.

During the shooting process, at least one of the four subjects of shooting subject A, shooting subject B, shooting subject C, and shooting subject D needs to leave during the shooting process and before the shooting is completed, such as shooting subject A , shooting object B, shooting object C, and shooting object D will leave one after another, then, in this step, the value of N is 4, for shooting object A, after detecting the shooting information of shooting object A and the shooting of the corresponding reference composition object If the information matches, acquire the first intermediate image corresponding to the subject A; next, for the subject B, if it is detected that the photographing information of the photographing subject B matches the photographing information of the corresponding reference composition object, acquire Take a second intermediate image corresponding to object B; then, for object C, when it is detected that the shooting information of object C matches the shooting information of the corresponding reference composition object, acquire a third intermediate image corresponding to object C ; Finally, for the shooting object D, when it is detected that the shooting information of the shooting object D matches the shooting information of the corresponding reference composition object, obtain the fourth intermediate image corresponding to the shooting object D, and obtain 4 intermediate images. In this way, after the first intermediate image is acquired, the subject A can leave, and the subjects B, C and D can continue to pose. Even if someone leaves during the shooting process, the normal progress of the photographing will not be affected.

In the embodiment of the present invention, since each intermediate image is an image obtained by collecting an image of a subject, and since the collected image is not the final output image, it is called an intermediate image in the embodiment of the present invention . It should be understood that, in the embodiment of the present invention, the intermediate image of the shooting object may be the subject image of the shooting object. The main image of the subject includes an image including only the subject itself (only the subject), or the main image of the subject includes not only the image including the subject itself, but also an image of the background within a certain range around the subject. In the embodiment of the present invention, each object may have a corresponding intermediate image. After the intermediate image is obtained, the intermediate image corresponding to the shooting object can be displayed on the shooting preview interface.

Step 130 , based on the N intermediate images, image synthesis is performed to output a target image.

After the intermediate images of each shooting object are obtained, the N intermediate images can be combined to obtain a target image and output.

In the multi-person photographing method provided by the embodiment of the present invention, the reference composition object is displayed first, and the reference composition object is used as a reference. When it is detected that the shooting information of each shooting object matches the shooting information of the corresponding reference composition object, the The intermediate images corresponding to each shooting object are combined, and the target image is output. In the embodiment of the present invention, when the shooting information of each shooting object matches the shooting information of the corresponding reference composition object, the corresponding intermediate image can be automatically acquired. In the middle image, other subjects can continue to pose, even if someone leaves during the shooting process, it will not affect the normal process of taking pictures, thus ensuring that there is no delay in the shooting progress.

In the embodiment of the present invention, in step 120, for each of the N shooting objects, if it is detected that the shooting information of the shooting object matches the shooting information of the corresponding reference composition object , acquiring the intermediate image corresponding to the shooting object, and obtaining N intermediate images may include: for the i-th shooting object among the N shooting objects, after detecting that the shooting information of the i-th shooting object is consistent with the i-th reference If the shooting information of the composition object matches, acquire the i-th intermediate image of the first area including the i-th shooting object; update the display content of the target area to the i-th intermediate image; where 0<i≤ N.

In the embodiment of the present invention, N represents the total number of shooting objects, and i represents any shooting object among the N shooting objects. In the process of acquiring an intermediate image of one of the N shooting objects, it is sequentially detected whether each shooting object matches its corresponding shooting information, and if the two match, an intermediate image of each shooting object is obtained, And replace the display content of the target area, and display this intermediate image in the target area. In this way, for any one of the N shooting objects, its corresponding intermediate image can be obtained and displayed in the above manner.

It should be noted that, in the case that the terminal only has a main screen, the target area may be a display area on the main screen of the terminal. At this time, the updating the display content of the target area to the ith intermediate image may include: updating the display content of the preview image area of the first area of the shooting preview interface to the ith intermediate image. Wherein, the target area includes a preview image area of the first area of the shooting preview interface. In the case that the terminal has dual screens (i.e., a main screen and a secondary screen), updating the display content of the target area to the i-th intermediate image may include: including the first screen and the second screen on the terminal , and when the shooting preview interface is displayed on the first screen, the ith intermediate image is displayed in a second area corresponding to the first area in the second screen. Wherein, the target area includes a second area corresponding to the first area in the second screen. In the embodiment of the present invention, the shooting preview interface and the intermediate image are respectively displayed on two screens, which can make viewing more convenient. In this way, it is more convenient for the user to view the image effect of the current subject after obtaining the intermediate image of each subject, and to view the final multi-person shooting effect after all the subjects are photographed. In this way, the target area can be either the preview image area where the corresponding subject is located on the main screen, or the second screen where the double-sided screen is different from the first screen where the preview interface is located, which can be applied to single-screen or dual-screen smart terminal.

Further, after updating the display content of the target area to the ith intermediate image, it further includes:

A prompt message is displayed, the prompt message prompts that the shooting preparations for the i-th object to be photographed have been completed. For example, the i-th intermediate image is the intermediate image corresponding to the subject A, and the preview interface may display "subject A's shooting preparations have been completed, you can leave, others can continue to pose", thus prompting subject A to leave.

In the multi-person photographing method provided in the embodiment of the present invention, optionally, before performing image synthesis based on the N intermediate images in step 130, and outputting the target image, the image of the object to be photographed in the shooting preview interface may also be obtained. number; determining M reference composition objects based on the number of shooting objects, where M=N; displaying the M reference composition objects. In the embodiment of the present invention, the number of reference composition objects displayed on the shooting preview interface is the same as the number of shooting objects. In this way, one-to-one correspondence between the reference composition object and the shooting object can be guaranteed, making it easier to take pictures of multiple people. At the same time, by displaying all the reference composition objects at one time, it can play a reference role, which is helpful for subsequent matching of shooting information of the shooting objects one by one.

In the multi-person photographing method provided in the embodiment of the present invention, optionally, before performing image synthesis based on the N intermediate images in step 130 and outputting the target image, the k-th shot in the shooting preview interface can also be determined The kth reference composition object of the object, and display the kth reference composition object in the shooting preview interface; when the shooting information of the kth shooting object matches the shooting information of the kth reference composition object, determine The k+1th reference composition object of the k+1th photographic object in the shooting preview interface, and display the k+1th reference composition object in the shooting preview interface; wherein, 0<k≤N. The method of determining the position of the next reference composition object based on the previous reference composition object in the embodiment of the present invention can make the positions of the reference composition objects have a certain correlation, and then have a better spatial position relationship, thereby ensuring the final composition. Images are better.

In the multi-person photographing method provided in the embodiment of the present invention, optionally, performing image synthesis based on the N intermediate images in step 130, and outputting a target image may include:

In the case that the N intermediate images constitute all the image content of the target image, the N intermediate images are synthesized into the target image and output. That is to say, when each intermediate image is acquired, each intermediate image includes images of the background within a certain range around the subject, so that after acquiring the intermediate images of all the subjects, all the intermediate images can be directly synthesized The target image can be obtained without obtaining the background image separately.

In the case where the N intermediate images constitute part of the image content of the target image, acquire the background image displayed on the shooting preview interface, and synthesize the N intermediate images and the background image into the target image and output. That is to say, when acquiring each intermediate image, only the images contained in the outline of the corresponding object can be extracted, so that each intermediate image only includes the image of the object itself (only including the object). In this case, After obtaining the intermediate images of all shooting objects, it is also necessary to obtain the background image displayed on the shooting preview interface, wherein the background image is an image of other areas in the target image except all shooting objects, so that the The N intermediate images and the background image are synthesized into a complete target image and output.

In this embodiment of the present invention, the reference composition object may be a subject in a composition recommendation template. The composition recommendation template may come from the composition recommendation module library, and may be obtained in various ways. For example, a manner of determining a composition recommendation template may be: randomly selecting a composition recommendation template from a composition recommendation template library as the determined composition recommendation template. Another way of determining a composition recommendation template may be, for example: presenting a plurality of composition recommendation templates, each of the plurality of composition recommendation templates includes compositions of a plurality of subjects; Selection of a composition recommendation template among the plurality of composition recommendation templates; using the selected composition recommendation template as a determined composition recommendation template.

In the embodiment of the present invention, the determined composition recommendation template includes compositions of multiple subjects, where the number of subjects included in the composition recommendation template may be equal to the total number of photographed objects. In the determined composition recommendation template, the position of a subject may be selected as the reference position of the shooting object. The process of selecting the composition position of a subject as the reference position of the first subject may be: presenting the determined composition recommendation template; receiving a user's selection of a subject position in the composition recommendation template; The position of the subject serves as the reference position of the subject.

In this embodiment of the present invention, an unselected subject may be selected from the determined composition recommendation templates as a reference composition object.

In an embodiment of the present invention, after the composition recommendation template is determined, all subjects in the composition recommendation template may be displayed on the shooting preview interface. In the embodiment of the present invention, all subjects in the determined composition recommendation template may be displayed on the shooting preview interface until all subjects are photographed. Of course, in the embodiment of the present invention, all subjects in the determined composition recommendation template may also be displayed first, and after a subject in the composition recommendation template is selected, only the selected subject may be displayed on the shooting preview interface . That is to say, in this embodiment of the present invention, all the subjects in the recommended composition template can be displayed all the time, or all the subjects in the recommended composition template that are determined can be displayed first. After the composition position is selected, only the selected subject is displayed.

In the embodiment of the present invention, taking the first shooting object and the second shooting object as an example, after the intermediate image (for example, the subject image) of the first shooting object is displayed on the shooting preview interface, when shooting the second shooting object, On the shooting preview interface, there is no need to display the real-time picture of the first shooting object again. In the embodiment of the present invention, when shooting the second object, the shooting preview interface can only be used to shoot the second object, while ignoring or not shooting other objects (for example, after the shooting of the previous object of the second object is completed , you can leave the shooting location). In this way, in the embodiment of the present invention, individual shooting of each shooting object in multiple shooting objects can be realized one by one.

In the multi-person photographing method provided by the embodiment of the present invention, the reference composition object is displayed first, and the reference composition object is used as a reference. When it is detected that the shooting information of each shooting object matches the shooting information of the corresponding reference composition object, the The intermediate images corresponding to each shooting object are combined, and the target image is output. In the embodiment of the present invention, when the shooting information of each shooting object matches the shooting information of the corresponding reference composition object, the corresponding intermediate image can be automatically acquired. In the middle image, other subjects can continue to pose, even if someone leaves during the shooting process, it will not affect the normal process of taking pictures, thus ensuring that there is no delay in the shooting progress.

The present invention will be further explained with specific embodiments below in conjunction with the accompanying drawings. In the following description, the subject in the composition recommendation template may be the reference composition object mentioned above. At the same time, it should be understood that, in the following, the shooting information is taken as the shooting location as an example for illustration. The method for taking pictures of multiple people when the shooting information is a shooting posture can be similarly obtained.

Figure 2 shows a method for taking pictures of multiple people. As shown in Figure 2, the multi-person photographing method provided by the embodiment of the present invention may include:

Step 201, enabling the composition position recommendation function.

The terminal device can provide an on/off entry of the composition position recommendation function. After the terminal (for example, a camera) displays the shooting preview interface, the composition position recommendation function can be enabled according to the user's selection, and of course the composition position recommendation function can also be enabled by default. After the composition position recommendation function is turned on, the multi-person composition guidance interface can be displayed, for example, allowing users to select the number of people to take pictures.

Step 202, determining a composition recommendation template.

While selecting the number of people to take pictures, one or more composition recommendation templates for the selected number of people can be displayed on the main screen of the terminal for the user to choose a composition recommendation template from among them, and the composition recommendation template selected by the user can be used as the current composition recommendation template. Certainly, when determining the composition recommendation template, a composition recommendation template may also be randomly selected from the composition recommendation template library as the current composition recommendation template.

Step 203 , in the determined composition recommendation template, select a subject as a reference composition object of the current subject.

This step can be specifically as follows: the user selects a subject from the determined composition recommendation template as a reference composition object of the current subject, or detects the posture of the current subject, and uses the determined composition recommendation template that matches the posture The subject serves as the reference composition object for the current subject.

Step 204, if the shooting position of the current shooting object in the shooting preview interface coincides with the position of the reference composition object of the current shooting object, capture an intermediate image (subject image) of the current shooting object.

In the embodiment of the present invention, various operations may be used to trigger the operation of acquiring the subject image (cutout) of the current subject. For example, double-click the screen to operate, long-press the cutout area to operate, etc.

After the current subject is photographed, they can leave the shooting location without continuing to capture their images.

Step 205 , displaying the subject image of the current shooting object on the shooting preview interface, and taking a picture of the next shooting object.

When taking pictures of the next object to be photographed, the above steps 203 to 205 may be repeated. The difference may be that, when selecting a subject from the composition recommendation template, an unselected subject may be selected as a reference composition object for the next object to be photographed.

For each unphotographed object in the multiple photographed objects, step 203 to step 205 may be repeated until all photographed objects are photographed.

Taking a photo of four people as an example, the determined composition recommendation template may be as shown in FIG. 3A . The composition recommendation template in FIG. 3A contains four subjects, respectively the first subject 310, the second subject 320, the third subject 330 and the fourth subject 340 from left to right. Can be displayed as a dashed box until selected. In the composition recommendation template shown in FIG. 3A, the second subject 320 can be selected as a reference composition object for the first subject. As shown in FIG. is a solid line, appearing as body 321 . After the shooting of the first subject is finished, the subject image is collected (cut out), and displayed on the shooting preview interface at the position corresponding to the second subject 320, as shown in FIG. 3C, reference numeral 322 indicates The main image of the first subject is displayed. On the shooting preview interface, select the reference composition object for the second shooting object, for example, select the first subject 310, as shown in Figure 3D, after the first subject 310 is selected, its image can be changed from a dotted line to a solid line , rendered as body 311. After the shooting of the second subject is completed, its image is collected and displayed on the next shooting preview interface together with the collected image of the first subject, as shown in FIG. 3E , and reference numeral 312 shows The main image of the second subject is captured. Subsequently, you can continue to select the reference composition object for the next subject from the third subject and the fourth subject, and collect images until all the subjects are photographed to form the final group photo with multiple people.

In the embodiment of the present invention, the main body image of the current subject is collected and displayed on the shooting preview interface. In this way, when the next subject is photographed, there is no need to photograph the previous subject. The main image of the shooting object has been presented on the shooting preview interface, so that it can be used as a reference for the shooting of the current shooting object without collecting the previous image of the shooting object, and realizes better shooting of multiple shooting objects Effect.

In the embodiment shown in Fig. 2, it can be determined whether the composition position of the subject in the composition recommendation template matches the shooting position of the current subject, and after each person is photographed, the composition position of the next person is recommended from the composition recommendation template , the composition position of each subject in the composition recommendation template can always be displayed in the shooting preview interface, so as to facilitate the composition position selection.

It should be understood that, in the embodiment of the present invention, in addition to determining the reference composition object based on the composition recommendation template, the position of the reference composition object of the current object may also be obtained based on the position of the reference composition object of the last photographed object.

Specifically, if the current object to be photographed is not the first object to be photographed, at this time, the position of the reference composition object of the current object to be photographed may be acquired based on the position of the reference composition object of a previous object that has been photographed before the current object to be photographed. The position of the reference composition object of the current object to be photographed may also be obtained based on the position of the reference composition object of the previous object to be photographed and the golden section point on the shooting preview interface. For example, the shooting preview interface is divided by the above captured object, and the position of the golden section point of the remaining large shooting preview interface after division is taken as the position of the reference composition object of the current shooting object. Certainly, in the embodiment of the present invention, other suitable manners may also be used to acquire the shooting position of the current shooting object.

If the current shooting object is the first shooting object, the position of the corresponding reference composition object may also come from some specified composition positions, such as the center position of the screen, the third position of the screen, and the like.

For each shooting object, after obtaining the shooting position of the reference composition object corresponding to the shooting object, the shooting object can be collected under the condition that the shooting position of the shooting object in the shooting preview interface coincides with the position of the corresponding reference composition object the intermediate image.

After all the subjects are photographed, the captured images of all the subjects can be synthesized and output to form a picture taken by multiple people, that is, a group photo.

Refer to FIG. 4A to FIG. 4D. FIG. 4A shows, for example, the position of the reference composition object 410 corresponding to the first shooting object; when the shooting position of the first shooting object in the shooting preview interface coincides with the position of the reference composition object , collect (cut out) the image of the first object to be photographed, as shown in FIG. 4B , reference numeral 411 shows the subject image of the first object to be photographed; the follow-up can be based on the position of the collected image 411 shown in FIG. 4B The position of the reference composition object 420 for the next object to be photographed (that is, the second object to be photographed) is acquired, and the position of the reference composition object 420 of the second object to be photographed may be as shown in FIG. 4C for example; in the second object to be photographed When the shooting position in the shooting preview interface does not coincide with the position of the reference composition object 420 shown in FIG. 4C , the position of the reference composition object corresponding to the second shooting object can be reacquired, as shown in FIG. 4D , the reacquired first The shooting positions of the two shooting objects may be, for example, indicated by reference numeral 420 ′. Subsequently, it is possible to continue to detect whether the shooting position of the second shooting object in the shooting preview interface coincides with the position of the reference composition object 420' shown in FIG. 4D, and perform image acquisition when they overlap, and acquire the next reference composition again when they do not overlap. The location of the object. This goes on and on until all the subjects are photographed to form the final group photo taken by multiple people.

It should be understood that, in the embodiment of the present invention, the terminal may include a main screen and a secondary screen, the main screen may always display the shooting preview interface of the terminal, and the secondary screen may display the captured image of the subject. Specifically, in the embodiment of the present invention, whenever the main body image of the current shooting object is collected, the main body image of the current shooting object can be displayed on the secondary screen. At the same time, when all the shooting objects in the multiple shooting objects are photographed, the generated images of the multiple shooting objects may be displayed on the secondary screen.

Taking the embodiment shown in FIG. 2 as an example below, the relevant display of the main and secondary screens will be further explained with reference to FIGS. 5A to 5E . FIG. 5A shows the display of the primary and secondary screens when the composition recommendation template is determined. As shown in Figure 5A to Figure 5E, the upper blank image represents the display of the secondary screen, the lower image represents the display of the main screen, and the main screen displays four subjects from left to right: the first subject 510, the second subject 520, The third body 530 and the fourth body 540, before these four bodies are selected, can be displayed in the form of dotted boxes. FIG. 5B shows the main and secondary screen display when the second subject from left to right in the composition recommendation template is selected. After the second subject 520 is selected, its image can be changed from a dotted line to a solid line, presenting as Subject 521. FIG. 5C shows the main and secondary screen display after the first subject is photographed and the image is captured, and reference numeral 522 shows the main image of the first subject, and the subject image 522 of the first subject corresponds to For the second subject 520, the position of the subject image 522 of the first subject is the same as the composition position of the second subject 520. At this time, the subject image 522' of the first subject can be displayed on the secondary screen. FIG. 5D shows the main and secondary screen display when the first subject from left to right in the composition recommendation template is selected. After the first subject 510 is selected, its image can be changed from a dotted line to a solid line, presented as Subject 511.
