Description

Photo method and mobile terminal

Technical field

The present application relates to the field of mobile terminals, and more particularly, to a photographing method and a mobile terminal.

Background technique

In daily life, people often take photos with friends and family, leaving precious memories between each other. At this stage, group photo shooting usually needs to be done by a third party. For example, ask someone to help with shooting, shooting with the selfie stick, or shooting with the camera or mobile phone “delay for a few seconds”.

Although these methods can also be used for group taking, there are some disadvantages. For example, in some scenarios, you just can't find someone else to shoot for yourself. It is difficult to take a full-length picture with a selfie stick. In addition, the selfie stick mostly uses the front camera to complete the shooting, while the front camera lags behind the rear camera in terms of pixels and imaging effects. Shooting "delay for a few seconds", you can't see the shooting when shooting, especially in the case of multiple people taking photos, you may need to try multiple times.

detailed description

The technical solutions provided by the present application will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of a photographing method 100 provided by the present application. Method 100 can be performed by a mobile terminal.

110. The mobile terminal acquires a first user instruction, starts a photographing application according to the first user instruction, and opens a viewfinder window.

The first user instruction is an instruction input by the user for launching the photographing application. After the camera application is launched, the viewfinder window is automatically opened.

In the embodiment of the present application, the photographing includes two stages, and the following is respectively recorded as the first stage and the second stage. The first phase corresponds to the following step 120, and the second phase corresponds to the following step 130. The two phases are described in detail below.

The first stage:

120. The mobile terminal acquires a second user instruction, and performs a first stage of shooting on the first object presented in the first shooting window to obtain a first image, where the first shooting window is the first part of the framing window.

In step 110, after the photo application is launched, the viewfinder window is opened. Referring to FIG. 2, FIG. 2 is a schematic diagram of opening a viewfinder window after the mobile terminal starts the photographing application. Options such as "photo", "panoramic", "video", etc. may also be displayed on the display screen of the mobile terminal. After the user clicks "Photos", the user enters the first stage of shooting.

Figure 3 is a schematic diagram of the first stage of shooting. As shown in FIG. 3, in the first stage of shooting, the first shooting window is a part of the framing window, which is recorded as the first part of the framing window. In FIG. 3, for example, the first shooting window is located on the left side of the framing window. For example, the first shooting window may also be located in the middle or the right side of the framing window.

The technical solution of the embodiment of the present application is directed to shooting "photographed". In other words, there are at least two people involved in the shooting. The first stage is the process of shooting a part of the at least two objects. The second stage is a process of photographing the remaining objects other than the subjects involved in the first stage of shooting.

For the convenience of explanation, only the objects participating in the photographing are taken as two. The first stage is to shoot one of the objects, the second stage is to shoot the other, and finally the group photo is taken to obtain the group image of the two objects. The example is explained. The process of taking a group photo is similar when there are more than two people participating in the group photo.

second stage

130. The mobile terminal acquires a third user instruction, and performs a second stage of shooting on the second object presented in the second shooting window to obtain a second image, where the second shooting window is a second part of the framing window.

The second stage is the process of taking a second object. Here, the second object is an object other than the first object among the objects participating in the group photographing. The second object is also at least one. The second object together with the first object constitutes an object that participates in taking a photo (or, a group photo).

Figure 4 is a schematic diagram of the second stage of shooting. As shown in FIG. 4, the second shooting window is also a part of the framing window, which is recorded as the second part of the framing window.

During the process of capturing the second object, the mobile terminal continuously displays the first image captured in the first stage.

In the embodiment of the present application, the first shooting window is presented to the user in the first stage of the mobile terminal in capturing the first object. The second shooting window is presented to the user by the mobile terminal in the second phase of capturing the second object. The first shooting window and the second shooting window may respectively occupy different positions of the framing window. The size of the first shooting window and the second shooting window may be the same or different.

It should be noted that the first image and the second object are simultaneously presented, and the mobile terminal determines whether the background image of the first object in the first image and the background image of the second object in the second shooting window satisfy the condition for splicing the image ( That is, the splicing condition). In the case where the background image of the first object and the background image of the second object satisfy the splicing condition, the shooting of the second object is completed to obtain a second image. Subsequently, by stitching the first image and the second image, a group image of the first object and the second object is obtained.

Alternatively, if the splicing condition is not satisfied, the mobile terminal presents the prompt information to the user to prompt the user to adjust the position of the second object, the backlight of the second object, and the like, thereby satisfying the splicing condition, and finally completing the group photo. Shooting. The second phase of the shooting process will be described in detail below.

The splicing condition mentioned in the embodiment of the present application refers to a condition that two images can be spliced. For example, two images that are stitched need to have overlapping portions. The image stitching technology has been relatively mature, and the specific implementation can refer to the prior art.

Panorama shooting If the camera moves too far during image capture, the front and back background differences will automatically cancel the photo. In the embodiment of the present application, since the photographer needs to exchange the photographer, the scene is not canceled when the scene is encountered, and when the front and back backgrounds reach the splicable condition, a photographable prompt is given, and the photographing can be continued.

140. The mobile terminal generates a group image of the first object and the second object according to the first image and the second image.

Through steps 120 and 130, the mobile terminal completes the shooting of all the objects participating in the group. In step 140, the mobile terminal performs splicing processing on the first image and the second image to obtain a group photo of the first object and the second object.

In the photographing method of the embodiment of the present application, in the process of taking a group photo, the subject who participates in the group photographing can complete the group photographing without the assistance of a third party (for example, with the help of a selfie stick or a passerby, etc.). . As shown in FIG. 5, FIG. 5 is a schematic diagram of a group image.

In the embodiment of the present application, the first phase and the second phase are sequential in time sequence. Therefore, in a possible implementation manner, in the first stage, when the mobile terminal presents the first shooting window to the user, only the first shooting window may be presented instead of the second shooting window. In another possible implementation manner, when the mobile terminal presents the first shooting window to the user in the first stage, the second shooting window may be presented at the same time. However, the second shooting window is not available. It should be understood that the fact that the shooting window is not available here means that the shooting window is in a non-framing state.

Specifically, after the mobile terminal acquires the third user instruction, if it is determined that the background image of the second object and the background image of the first object satisfy the image splicing condition, the second object presented in the second shooting window is captured, and obtained Second image.

It is known from the foregoing step 140 that the group image in the embodiment of the present application is obtained by separately photographing at least two objects participating in the group photographing, and then performing stitching processing on the separately photographed images. Therefore, the first image obtained by capturing the first object and the second image obtained by capturing the second object need to satisfy the condition of splicing (hereinafter referred to as splicing condition). To put it another way, the background image when the first object is photographed and the background image when the second image is taken only satisfy the splicing condition, and then the splicing of the image can be performed later, thereby obtaining a group image.

Therefore, in the embodiment of the present application, after the shooting of the first stage is completed, when the second stage of shooting is performed, the mobile terminal automatically detects whether the background image of the second object and the background image of the previous first object satisfy the splicing condition. And, when the splicing condition is satisfied, the shooting of the second object is completed.

When the mobile terminal determines that the background image of the second object and the background image of the first object do not satisfy the splicing condition, the mobile terminal presents the first prompt information, where the first prompt information is used to prompt to adjust the background image of the second object until the first The background image of the two objects and the background image of the first object satisfy the splicing condition.

In the actual operation, it is assumed that the first object is referred to as user #A, and the second object is referred to as user #B. In the first stage, User #A takes the phone to complete the shooting of User #B. Next, the user #A exchanges the role with the user #B, and the user #B takes a picture of the user #A. During the shooting process, if the background of the user #A and the background of the user #B differ greatly in the background of the first stage, and the splicing condition of the background image is not satisfied, the mobile terminal presents the prompt information, for example, the mobile terminal displays in the framing window. "Please adjust the shooting background". In this way, the user #B informs the user #A to adjust the position of the station, and adjusts the position by taking the background of the user #B as the main background. The splicing condition is satisfied until the background image of the first stage and the background image of the second stage. At this point, the prompt information can be automatically revoked, or it is no longer displayed. Show information.

The following describes the requirements for the background image during the filming process.

Figure 6 is another schematic view of the first stage of shooting. As shown in FIG. 6, in the first stage, the user #A takes a mobile phone to shoot the user #B. The scene other than the user #B in the first shooting window is the background image of the user #B.

Figure 7 is another schematic view of the second stage of shooting. As shown in FIG. 7, in the second stage, user #A and user #B exchange roles, and user #B performs shooting on user #A. The scene other than the user #A presented in the second shooting window is the background image of the user #A.

When the second stage of shooting is performed, the mobile terminal determines whether the background image of the user #A and the background image of the user #B in the first stage satisfy the splicing condition. In the case that the image stitching condition is satisfied, the mobile terminal will continue the second stage of shooting. Otherwise, the mobile terminal will display a prompt message prompting the user to adjust the background of the shooting until the stitching condition is satisfied between the background image of the second stage and the background image of the first stage. The resulting group photo is shown in Figure 8. Fig. 8 is another schematic diagram of a group image.

Further, the method further includes: before the mobile terminal device determines that the background image of the second object and the background image of the first object satisfy the splicing condition, before the second object presented in the second shooting window is photographed, the method further includes:

The mobile terminal performs face recognition on the first object and the second object to determine a face position of the first object and a face position of the second object;

The mobile terminal photographs the second object presented in the second shooting window in a case where it is determined that the face position of the second object does not coincide with the face position of the first object.

It should be understood that in order to avoid the occlusion of the face of a certain object (some objects may be some), the second object of the second stage is judged by the face recognition technology when performing the second stage of shooting. Whether the face position coincides with the face position of the first object photographed in the first stage. And in the case where it is determined that there is no coincidence, the second object is photographed.

When the mobile terminal determines that the face position of the second object coincides with the face position of the first object, the mobile terminal presents the second prompt information, where the second prompt information is used to indicate that the face of the second object is adjusted to be the second The position within the shooting window.

In the actual operation, in the first stage, the user #A holds the mobile phone to complete the shooting of the user #B. In the second stage, the user #A is photographed by the user #B. Before the second object is photographed, if the mobile terminal detects that the face position of the user #A coincides with the face position of the user #B, the prompt information is presented on the display screen. For example, the mobile terminal displays "Please adjust the face position" on the display screen in the framing window. User #B informs user #A to adjust the face position until the face position of user #A does not coincide with the face position of user #B. At this point, the prompt information can be automatically revoked. Thereafter, the mobile terminal can take a picture of User #A.

Face recognition technology first detects a person's face in the shooting window. Preprocessing is performed after the face is detected and the key feature points of the face are located. Then, through the recognition algorithm, the face features are extracted, and finally the recognition is completed. Face feature extraction is mainly based on modeling methods. In the embodiment of the present application, the face modeling method in the prior art can be used to complete the face recognition. For example, an earlier version of Android (Android) has implemented camera-integrated face recognition technology and provides a common interface for use by some third-party Android installation packages (AndroidPackage, APK). The group shooting mode can be used directly.

The face recognition technology mainly performs the following detection in the embodiment of the present application:

(1) Faces in Image 1 and Image 2 must be guaranteed to be complete.

(2) When generating a group photo, the face contours in Image 1 and Image 2 are guaranteed to be complete to avoid group distortion.

FIG. 9 is a schematic diagram of a face recognition technique applied to a group photographing in the embodiment of the present application. As mentioned earlier, in In the second stage, the mobile terminal detects whether the face position of the second object coincides with the face position of the first object. In the case of coincidence, the second object is prompted to adjust the face position. Subsequently, in the process of adjusting the position of the face by the second object, the mobile terminal acquires the adjusted face position of the second object in real time, and determines that the adjusted face position of the second object and the face position of the first object are not In the case of coincidence, the second stage of the second object is adjusted in the second shooting window to obtain a second image.

During the second stage of shooting, if the background image of the second object and the background image of the first image do not satisfy the splicing condition, or the face position of the first object and the face position of the second object coincide. The mobile terminal will present a prompt message to the user. The user adjusts the position of the second object or the position of the face of the second object in the second shooting window at the prompt of the prompt information. After determining that the adjusted background image of the second object and the background image of the first object satisfy the condition of image stitching, and the face position of the second object does not coincide with the face position of the first object, the mobile terminal pairs The second object is photographed to obtain a second image.

After the second image is captured, the mobile terminal performs a splicing process on the first image and the second image based on an instruction input by the user to obtain a group image of the first object and the second object.

For example, after the first image and the second image are captured, the “generating a group” is displayed on the mobile terminal. After the user clicks, the mobile terminal performs a splicing process on the first image and the second image to generate a group photo of the first object and the second object. image.

The photographing method of the embodiment of the present application can be implemented by adding a "photographing" mode to a mobile terminal (for example, a camera or a mobile phone).

FIG. 10 is a schematic diagram of adding a group photographing mode in a photographing application of a mobile terminal. As shown in FIG. 10, after the user opens the photo application, the group photo shooting can be performed by selecting the “photo shooting” mode. The specific shooting process is as described above and will not be described here.

301. The user turns on the photo application on the mobile phone and selects the group shooting mode.

The user referred to here is any one of the objects participating in the shooting. For example, user #A and user #B want to take a group photo, and the user mentioned in step 301 can be user #A or user #B. In fact, it can also be a third person other than User #A and User #B. However, the technical solution provided by the present application is for the purpose of completing the group photographing without the assistance of the third party. Therefore, the situation of the third person is not considered in the embodiment of the present application.

302. Person #A holds the mobile phone and shoots the person #B.

Step 302 is the shooting of the first stage mentioned above.

303. The first stage of shooting is completed.

Next, the person #A and the person #B exchange roles and enter the second stage of shooting.

304, Person #B holding a mobile phone to shoot #A.

Step 304 is the shooting of the second stage described above.

305. Whether the background image of the mobile phone judgment person #A and the background image of the person #B satisfy the splicing condition.

If the splicing condition is not met, the mobile phone performs step 306.

306. The mobile phone displays prompt message #1.

It should be understood that the prompt information #1 prompts the user to adjust the background of the person #A until the background image of the person #A and the background image of the person #B satisfy the splicing condition.

As mentioned above, if the camera moves too far when the image is taken during panorama shooting, the background difference before and after the background is automatically canceled. In the embodiment of the present application, since the group photographing needs to exchange the photographer, this is encountered. The scene does not cancel the shooting state, and when the front and back backgrounds reach the splicable condition, a prompt that can be taken is given, and the photographing can be continued. Based on this difference, in the embodiment of the present application, it is recommended to adopt a loop check mode until the second image and the first image satisfy the splicing condition (see the dotted line frame portion in FIG. 11). For example, the time interval can be set for each check.

If the splicing condition is met, the mobile phone performs step 307.

307. Whether the face of the mobile phone judgment person #A and the face of the person #B overlap.

Similar to step 305, if coincident, step 308 is performed. If not, step 309 is performed.

308. The mobile phone displays prompt message #2.

The prompt information #2 prompts the user to adjust the face position of the person #A until the face of the person #A and the face of the person #B do not coincide.

309. The second stage of shooting is completed.

310. The user clicks “Generate a group photo”.

311. The group photo was taken.

The mobile phone spliced the image of the person #B photographed in the first stage with the image of the person #A photographed in the second stage, and synthesized a group image of the person #A and the person #B. The group photo was taken.

The photographing method provided by the present application respectively completes the photographing of the group photo by dividing the group photographing into the first stage shooting and the second stage shooting. The stitching process is performed on the images taken by the group members to generate a group image. Therefore, the photographing method provided by the present application can complete the group photographing without the assistance of a third party.
