Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The shooting method of the embodiment of the invention is applied to a mobile terminal, the mobile terminal comprises a first front camera, a second front camera and a display screen, and specifically, as shown in fig. 1, the display screen specifically comprises: the backlight module comprises a display panel 1, a backlight 2 and a light guide plate 3, wherein the backlight 2 comprises at least two light source assemblies 21, and each light source assembly 21 is arranged on different sides of the light guide plate 3.

Specifically, light emitted by a first light source assembly 21 of the at least two light source assemblies 21 is projected to the display panel 1 through the light guide plate 3 at an incident angle not smaller than a first angle to form a first full screen image; the light emitted by the second light source assembly of the at least two light source assemblies 21 is projected to the display panel 1 through the light guide plate 3 at an incident angle not smaller than the second angle to form a second full screen image. Wherein, the visible range of the first full screen picture is as follows: the first light source assembly emits the light ray angle range of the display panel 1 at an exit angle not smaller than the first angle, and the visible range of the second full screen picture is as follows: the second light source assembly emits light out of the display panel 1 at an exit angle not less than the second angle. Therefore, when the users share the screen, the users can respectively see the respective full-screen pictures in the own visual angle range. Furthermore, the visible range of the second full-screen image and the visible range of the first full-screen image are not overlapped within a preset angle range, so that the images among different users are not interfered and influenced, and the user experience is improved.

Further, at least two sets of light guide surfaces 31 with different inclination angles are disposed on one side of the light guide plate 3 away from the display panel 1. Wherein, the inclination of every group leaded light face 31 is the same, and a light source subassembly 21 corresponds a set of leaded light face 31, and the effect of leaded light face 31 is the direction of projection that will guide the light that corresponds light source subassembly 21 and send, and specifically, leaded light face 31 can be thrown away with fixed refraction angle with the light of throwing to self.

Specifically, the first light source assembly and the second light source assembly are disposed opposite to each other, and the two sets of light guide surfaces 31 of the light guide plate 3 form at least one zigzag groove surface. The number of each group of light guide surfaces 31 is equal to the number of the formed zigzag groove surfaces, for example, one group of light guide surfaces 31 includes one light guide surface 31, and then the number of the zigzag groove surfaces formed by two groups of light guide surfaces 31 is one. The light guide surface 31 with the first inclination angle in the sawtooth-shaped groove surface is used for guiding the light projection direction of the first light source assembly, and the light guide surface 31 with the second inclination angle in the sawtooth-shaped groove surface is used for guiding the light projection direction of the second light source assembly.

Further, as shown in fig. 2, the first light source assembly and the second light source assembly are disposed oppositely, the backlight 2 further includes a third light source assembly and a fourth light source assembly disposed oppositely, the first light source assembly, the second light source assembly, the third light source assembly and the fourth light source assembly enclose a quadrangle, and correspondingly, the light guide surface 31 of the light guide plate 3 forms at least one square-cone-shaped groove surface. Wherein, the number of each group of light guide surfaces 31 is equal to the number of the square tapered groove surfaces formed, for example, a group of light guide surfaces comprises four light guide surfaces 31, and the number of the zigzag groove surfaces formed by the light guide surfaces is four. The light guide surface 31 with the third inclination angle in the square conical groove surface is used for guiding the light projection direction of the first light source assembly, the light guide surface 31 with the fourth inclination angle in the square conical groove surface is used for guiding the light projection direction of the second light source assembly, the light guide surface 31 with the fifth inclination angle in the square conical groove surface is used for guiding the light projection direction of the third light source assembly, and the light guide surface 31 with the sixth inclination angle in the square conical groove surface is used for guiding the light projection direction of the fourth light source assembly.

Further, in order to enhance the light transmittance, a non-light-transmitting lampshade 4 covers each light source assembly 21, and the non-light-transmitting lampshade 4 can limit the light emitted by each light source assembly 21 within a preset angle, and ensure that the light source assembly 21 avoids the light leakage phenomenon.

Each light source assembly 21 includes at least one row of leds, and each row of leds includes at least one led, wherein light between different leds is not blocked.

The mobile terminal display screen comprises at least two groups of light source components, wherein light rays emitted by the first light source components form a first full screen picture through the display panel, and light rays emitted by the second light source components form a second full screen picture through the display panel, so that a user can view respective full screen pictures when the screen is shared. In addition, the visible range of the second full-screen image and the visible range of the first full-screen image are not overlapped within a preset angle range, so that the respective full-screen images can not interfere and influence the images of the other side when different users share the screen, and the user experience is further improved.

Further, as shown in fig. 3, the shooting method provided by the embodiment of the present invention specifically includes the following steps:

step 301: and acquiring first face data acquired by the first front camera and second face data acquired by the second front camera.

The first face data and the second face data are image data or video data including faces. Specifically, mobile terminal includes backlight and display panel, and the backlight includes two at least light source subassemblies, and different light source subassemblies correspond the first face data that first leading camera gathered and the second face data that the leading camera of second gathered respectively. Specifically, when two users, namely a left user and a right user, share the self-timer at the same time, the left user A located in the visual range of the first full-screen picture collects first face images or video data through the first front-facing camera, and the right user B located in the visual range of the second full-screen picture collects second face images or video data through the second front-facing camera.

Step 302: and controlling a display screen to alternately display the first face data and the second face data according to a preset display frame rate.

When the user starts the self-timer sharing, the first face data or the second face data corresponding to each light source assembly are alternately displayed according to the preset display frame rate, so that the effect of sharing self-timer by different users is achieved. For example, the first light source component corresponds to the first front-facing camera, so as to control the display screen to display first face data for a left user a located in the visible range of the first full-screen picture to watch, and the second light source component corresponds to the second front-facing camera, so as to control the display screen to display second face data for a right user B located in the visible range of the second full-screen picture to watch.

Based on the structure of the display screen, the embodiment of the invention can realize that two full-screen images can be watched in different angle ranges, specifically, first face data collected by a first front-facing camera can be watched in the visual range of a first full-screen image, and second face data collected by a second front-facing camera can be watched in the visual range of a second full-screen image, so that two users can watch two full-screen self-shooting images without mutual influence.

Further, step 302 specifically includes: turning on the first light source component, turning off the second light source component at the same time, and controlling the display screen to display the first face data; after a preset time interval, closing the first light source component, simultaneously opening the second light source component, and controlling the display screen to display second face data; after the preset time interval, the first light source component is started and the second light source component is simultaneously closed in a circulating execution mode, the step that the display screen displays the first face data is controlled to reach the preset time interval, the first light source component is closed, the second light source component is started simultaneously, and the step that the display screen displays the second face data is controlled until the screen sharing function is detected to be closed, or until the first front camera or the second front camera is detected to be closed.

Specifically, after the display screen is lighted, the shot data picture is refreshed and displayed according to a preset frame rate, the LED lamps on the two sides are simultaneously turned on, at this time, the mobile terminal detects the turning-on state of the screen sharing function, and if the turning-on state is detected to indicate that the screen sharing function is turned on and the first front camera and the second front camera are both turned on, the first face data collected by the first front camera and the second face data collected by the second front camera are acquired, that is, step 301 is executed. If the on-state is detected to indicate that the screen sharing function is off or the first front camera or the second front camera is off, all light source assemblies in the backlight source are turned on, namely the LED lamps on the two sides are turned on simultaneously.

The specific implementation principle of the screen sharing function when two users (left user a and right user B) shoot simultaneously will be further described below with reference to the specific schematic timing diagram of alternately lighting the LEDs. Specifically, as shown in fig. 4, (1) the right LED lamp is turned on, and the left LED lamp is turned off at the same time, the first frame of the display panel first displays the first frame display content of the first face data collected by the first front camera, and at this time, only the left user a can see the frame display content. (2) After the interval of the preset time interval, the right LED lamp is turned off, the left LED lamp is turned on at the same time, the second frame of the display panel displays the first frame display content of the second face data collected by the second front camera, and only the right user B can see the picture display content. (3) After the interval of the preset time interval, the LED lamp on the right side is turned on, the LED lamp on the left side is turned off at the same time, the third frame of the display panel displays the second frame display content of the first face data collected by the first front camera, and only the user A on the left side can see the picture display content at this time. (4) After the interval of the preset time interval, the right LED lamp is turned off, the left LED lamp is turned on at the same time, the fourth frame of the display panel displays the second frame display content of the second face data collected by the second front camera, and only the right user B can see the picture display content.

According to the method, the self-timer pictures collected by the first front camera and the second front camera are alternately displayed, and when the preset time interval is small enough, namely the preset display frame rate is fast enough, the left user and the right user can watch the continuous and non-flickering display contents. In order to ensure consistency of image display, the preset display frame rate in the embodiment of the present invention is generally greater than a display frame rate of a general display screen. Assuming that the display frame rate in the prior art is 60 frames/second, the preset display frame rate in the embodiment of the present invention needs to be 120 frames/second, so as to ensure the display effect of each data frame. That is, after the screen sharing function is turned on, the mobile terminal alternately displays self-timer frames of the left and right users, so that the left and right users can view the respective required pictures at the same time and can only view the respective required pictures.

Further, step 302 specifically includes: according to a preset display frame rate, when the display screen is controlled to display the first face data in a full screen mode, displaying second face data in a first preset area of the display screen; and when the display screen is controlled to display the second face data in a full screen mode, displaying the first face data in a second preset area of the display screen. Specifically, the first preset area and the second preset area may be a small window area in a display panel of the display screen, for example, a preview interface of the first front camera is displayed in a full screen image visible by the left user a, and a small window is reserved to display a preview interface of the second front camera; and displaying a preview interface of the second front camera in a full screen picture visible by the right user B, and reserving a small window to display the preview interface of the first front camera.

On the other hand, step 302 may further specifically include: dividing a display area of a display screen into a first display area and a second display area; according to a preset display frame rate, when the first display area is controlled to display the first face data, displaying second face data in the second display area; and when the first display area is controlled to display the second face data, the first face data is displayed in the second display area. That is, the first display region and the second display region may also both occupy 1/2 area of the display panel of the display screen. For example, a display panel of the display screen is divided into a left interface and a right interface which are equal in area, the left interface and the right interface respectively display preview interfaces of the first front camera and the second front camera, and two users can make the same expression according to the expression of the other user.

Further, after the step 302, the method further includes: detecting a first preset action for triggering expression snapshot; if the first preset action is detected, obtaining the expression similarity of the first face data and the second face data; and if the expression similarity is higher than a preset threshold value, respectively controlling the first front camera and the second front camera to execute shooting operation. Wherein, the first preset action comprises: at least one of a touch screen or spaced gesture control action, a head swing control action, a facial expression action, and a finger pointing control action. Therefore, when the expression similarity of the first face data and the second face data is higher than a preset threshold value, the self-timer pictures of different users can be shot simultaneously, and the expression synchronization of different users is realized. For example, the left user and the right user can respectively trigger a continuous shooting mode through a gesture instruction, the left user A and the right user B respectively start continuous shooting according to the expression of the other user in the preview small window, the spirit synchronization of the expressions of the two users is realized, and a series of interesting photos are captured.

Wherein, if a first preset action is detected, the step of obtaining the expression similarity of the first face data and the second face data comprises: if the first preset action is detected, starting a timer with preset duration; and when the preset duration of the timer is reached, obtaining the expression similarity of the first face data and the second face data. The trigger corresponding to the continuous shooting mode can be any one of the left-side user A and the right-side user B, for example, the left-side user A blinks 3 times to trigger a 3-second timer, after the time of the timer is up, the first front camera and the second front camera simultaneously start to detect the actions of the left-side user A and the right-side user B, when the expression similarity of the left-side user A and the right-side user B is detected to be larger than a preset threshold value, a snapshot operation is performed, and the subsequent snapshot operations are sequentially realized, so that different users can shoot a series of interesting photos with synchronous expressions when sharing self-shooting.

Further, after alternately displaying the first face data collected by the first front camera and the second face data collected by the second front camera, the method further includes: detecting whether a shooting control instruction is received or not; and if the shooting control instruction is detected, controlling the first front camera and/or the second front camera to execute shooting operation according to the shooting control instruction. And the shooting control instruction is associated with the rotation angle and the rotation direction of the first front camera and/or the second front camera. Specifically, first leading camera and the leading camera of second can be according to shooing control command, respectively according to certain angle deviation to corresponding user's auto heterodyne direction, and the angle of two leading cameras all can control the deflection, can the angle of the leading camera in left side be partial to left side user A's auto heterodyne direction, and the angle of the leading camera in right side is partial to right side user B's auto heterodyne direction.

Specifically, as shown in fig. 5, the first front camera 5 and the second front camera 6 are rear cameras with adjustable shooting angles, that is, both the first front camera 5 and the second front camera 6 can rotate. Specifically, the step of detecting whether the photographing control instruction is received includes: and respectively controlling the first front camera and the second front camera to perform control action detection. If the shooting control instruction is detected, the step of controlling the first front camera and/or the second front camera to execute the shooting operation according to the shooting control instruction comprises the following steps: if the first front-facing camera detects a first control action in the visible range of the first full-screen picture, controlling the first front-facing camera to execute shooting operation according to the first control action; and if the second front-facing camera detects a second control action in the visible range of the second full-screen picture, controlling the second front-facing camera to execute shooting operation according to the second control action. That is to say, through first leading camera and the second leading camera respectively the seizure control moves, the control move includes: at least one of a touch screen or spaced gesture control action, a head swing control action, a facial expression action, and a finger pointing control action. Head swing action includes turning round the head left and for camera certain angle of rotation left, upwards lifts the head and for certain angle of rotation upwards etc. touch screen or separate empty gesture action and include: draw "V", "O", etc. to specify the shape, the finger pointing control action includes: the finger is right for camera certain angle of rotation right, the finger upwards for camera certain angle of rotation upwards etc. facial expression action includes: blinking, smiling, etc. And if the first front-facing camera detects that the left user A twists the head leftwards in the visual range of the first full-screen picture, controlling the first front-facing camera to rotate leftwards by a certain angle and executing shooting operation. And if the second front-facing camera detects that the right user B twists the head leftwards in the visual range of the second full-screen picture, controlling the first front-facing camera to rotate leftwards by a certain angle and executing shooting operation.

Specifically, in a specific application process, a user unlocks the display screen and starts the camera, the LEDs on the two sides are controlled to be started simultaneously, and the display screen refreshes and displays a self-timer picture of the user. When a plurality of users shoot by themselves at the same time, whether the users click to enter the sharing self-shooting function is judged, if not, the LEDs on the two sides are continuously controlled to be simultaneously turned on, and a picture is displayed. If the fact that the user clicks to enter the shared self-timer function is detected, previews or shooting pictures of a first front camera and a second front camera (a left front camera and a right front camera) are displayed alternately according to a sequence diagram shown in a sequence diagram 4, so that the left shooting user and the right shooting user can watch self-timer full-screen previews or shooting pictures simultaneously. When the front cameras corresponding to the front cameras respectively detect that the user inputs an instruction for rotating the cameras, if the head swings up and down and left and right (the front cameras detect the instruction), when the fingers/palms point to the upper part, the lower part, the left part and the right part, the cameras respectively rotate a certain angle corresponding to the upper part, the lower part, the left part and the right part, the visual angle for shooting or previewing is changed, and the deviated angle is recorded.

Further, after the step 302, the method further includes: detecting a second preset action for finishing shooting; and if the second preset action is detected, controlling the first front camera and/or the second front camera to output the face image data or the face video data. Wherein the second preset action comprises at least one of a touch screen or an air gesture control action, a head swing control action, a facial expression action and a finger pointing control action.

Specifically, the step of detecting a second preset action for ending the photographing includes: respectively controlling the first front camera and the second front camera to carry out second preset action detection; if the second preset action is detected, the step of controlling the first front camera and/or the second front camera to output image data or video data comprises the following steps: if the first front-facing camera detects a second preset action in the visible range of the first full-screen picture, controlling the first front-facing camera to output face image data or face video data; and if the second front-facing camera detects a second preset action in the visible range of the second full-screen picture, controlling the second front-facing camera to output the face image data or the face video data. That is to say, when the user has a self-timer, preset actions such as blinking, scissors, smiling and the like are performed, and the current photo or video of the user is cached. For example, when the left-side user a takes a self-timer shot, preset actions such as blinking, scissors, smiling and the like are performed, and the picture or video of the left-side user a is cached. And when the right user B carries out self-shooting, executing preset actions such as blinking, scissors and smiling shooting, and caching the picture or video of the right user B.

On the other hand, detecting the preset action for ending the shooting may also be that the user clicks a corresponding function key, and specifically, the step of detecting the preset action for ending the shooting may also be implemented by: respectively detecting touch operations on a first shooting button in a first full-screen picture and a second shooting button in a second full-screen picture; if the preset action is detected, the step of controlling the first front-facing camera and/or the second front-facing camera to output the face image data or the face video data comprises the following steps: if a first touch operation on the first shooting button is detected, controlling the first front-facing camera to output image data or video data; and if the second touch operation on the second shooting button is detected, controlling the second front-facing camera to output the face image data or the face video data. That is to say, when the user needs to take a self-timer, the user can click the corresponding shooting button, and after the touch operation on the shooting button is detected, the current photo or video of the user is cached. For example, when the left user a needs to take a self-timer, the corresponding shooting button can be clicked, and after the touch operation on the shooting button is detected, the picture or video of the left user a is cached; when the right user B needs to shoot by oneself, a corresponding shooting button can be clicked, and after the touch operation on the shooting button is detected, the picture or the video of the right user B is cached.

Further, after the step 302, the method further includes: carrying out image synthesis on the first face data and the second face data to generate a face image; or performing video synthesis on the first face data and the second face data to generate a face video. Specifically, according to the recorded deviation angle of the camera, the first data collected by the first front camera and the second data collected by the second front camera are combined into a left-right wide-view-angle photo or video in the background. When two left and right users use different front-facing cameras to carry out self-shooting simultaneously, full-screen preview and shooting pictures corresponding to the left and right users can be displayed on a display screen simultaneously, the shooting angles of the users are further adjusted in modes of head rotation, gestures and the like by detecting the corresponding users through the front-facing cameras, and the users at the left and right corresponding visual angles only see the pictures needed by the users and cannot generate interference on the user pictures at the other visual angle. In addition, after the shooting is finished, the data shot by the two users can be synthesized to generate a large-view-angle photo or video.

The manner of acquiring the shooting control instruction through the front-facing camera is described above, and the manner of controlling the shooting process through voice will be further described below. Specifically, the step of detecting whether the photographing control instruction is received includes: acquiring voice data collected by a microphone; comparing the voice data collected by the microphone with pre-stored reference voice data; and if the voice data collected by the microphone is matched with at least one item of prestored reference voice data, determining that a shooting control instruction is received. Wherein the reference voice data includes: first reference voice data associated with the first front-facing camera, and second reference voice data associated with the second front-facing camera. That is to say, through gathering the speech information of user's input, control first leading camera and second leading camera and carry out angle rotation and shoot the operation.

In a specific application process, a user unlocks the display screen and starts the camera, the LEDs on the two sides are controlled to be started simultaneously, and the display screen refreshes and displays a shooting picture of the user. When a plurality of users shoot by themselves at the same time, whether the users click to enter the sharing self-shooting function is judged, and if not, the LEDs on the two sides are continuously controlled to be simultaneously turned on. If the fact that the user clicks to enter the shared self-shooting function is detected, previews or shooting pictures of a first front camera and a second front camera (a left front camera and a right front camera) are displayed alternately according to a sequence diagram shown in a sequence diagram 4, so that the left self-shooting user and the right self-shooting user can view self-shooting full-screen previews or shooting pictures simultaneously. Further, if a shooting control instruction is detected, the step of controlling the first front camera and/or the second front camera to execute the shooting operation according to the shooting control instruction comprises: if the voice data collected by the microphone is matched with the first reference voice data, controlling the first front-facing camera to execute shooting operation according to the voice data collected by the microphone; and if the voice data collected by the microphone is matched with the second reference voice data, controlling the second front-facing camera to execute shooting operation according to the voice data collected by the microphone. When the microphone collects the voice input of the left user A, namely up, down, left and right, the corresponding first front-mounted camera deflects by certain angles up, down, left and right respectively, and simultaneously records the angle difference of deflection of the corresponding camera, and when the microphone collects the voice input of the right user B, namely up, down, left and right, the corresponding second front-mounted camera deflects by certain angles up, down, left and right respectively, and simultaneously records the angle difference of deflection of the corresponding camera.

Further, before the step of detecting whether the shooting control instruction is received, the method further comprises: respectively displaying first prompt information and second prompt information on a first full-screen picture and a second full-screen picture; acquiring first reference voice information of a first user and second reference voice information of a second user, which are acquired by a microphone; and respectively establishing a first incidence relation between the first front camera and the first reference voice information and a second incidence relation between the second front camera and the second reference voice information. The first prompt message is used for prompting the first user to input voice information, and the second prompt message is used for prompting the second user to input voice information. That is, a prompt interface is displayed at the left screen view angle, the left user a is prompted to speak, and the voice data of the left user a is recorded through the integrated microphone and stored as the reference voice information. And similarly, a prompt interface is displayed at the viewing angle of the right screen to prompt the right user to speak, and the voice data of the right user B is recorded by the integrated microphone and stored as reference voice information.

Further, the step of detecting whether the shooting control instruction is received further comprises the following steps: detecting a preset action for ending shooting; and if the preset action is detected, controlling the first front camera and/or the second front camera to output image data or video data.

Specifically, the step of detecting the preset action for ending the shooting can also be realized by acquiring voice information. When a user carries out photographing or video recording operation, the user inputs voice information such as photographing and video recording through voice, the mobile terminal starts photographing or video recording after acquiring the corresponding voice information, and the current photo or video of the user is cached. The method further comprises the following steps after the step of controlling the first front camera and/or the second front camera to execute the shooting operation according to the shooting control instruction: image synthesis is carried out on the image data shot by the first front camera and the second front camera to generate a face image; or video synthesis is carried out on the video data shot by the first front camera and the second front camera to generate a face video. Specifically, according to the recorded deviation angle of the camera, the first face data collected by the first front camera and the second face data collected by the second front camera are combined into a left-right wide-view-angle photo or video in the background. When two left and right users use different front-facing cameras to shoot simultaneously, the self-shooting full-screen preview and the shooting picture of the left and right users can be displayed on the display screen simultaneously, the voice data of the left and right users are recorded, the user voice input camera deflection control signal is recognized, the corresponding front-facing camera deflects at a certain angle, the preview and shooting angle of view is adjusted, and the users at the left and right corresponding visual angles only see the required picture and cannot generate interference on the user picture at the other visual angle. In addition, after the shooting is finished, the data shot by the two users can be synthesized to generate a large-view-angle photo or video.

Further, besides the detecting the preset action according to the front-facing camera and the detecting the preset action according to the collected voice data, the embodiment of the present invention further provides a method for adjusting the shooting angle of the camera according to a face tracking method, and specifically, after step 302, the method further includes: respectively controlling a first front camera and a second front camera to track the face of a user, and determining the face position; and adjusting the shooting angle of the first front camera and/or the second front camera according to the position of the face. Specifically, the step of adjusting the shooting angle of the first front camera and/or the second front camera according to the face position includes: if the first face position tracked by the first front-facing camera exceeds the first shooting range of the first front-facing camera, controlling the first front-facing camera to rotate by an angle until the first face position is located in the first shooting range; and if the position of the second face tracked by the second front camera exceeds the second shooting range of the second front camera, controlling the second front camera to rotate by an angle until the position of the second face is within the first shooting range. The first shooting range is the central view field range of the first front camera, and the second shooting range is the central view field range of the second front camera.

Further, the step of detecting whether the shooting control instruction is received further comprises the following steps: detecting a preset action for ending shooting; and if the preset action is detected, controlling the first front camera and/or the second front camera to output image data or video data. Specifically, the method further comprises the following steps after the step of controlling the first front camera and/or the second front camera to execute the shooting operation according to the shooting control instruction: image synthesis is carried out on the image data shot by the first front camera and the second front camera to generate a face image; or video synthesis is carried out on the video data shot by the first front camera and the second front camera to generate a face video. Specifically, according to the recorded deviation angle of the camera, the first face data collected by the first front camera and the second face data collected by the second front camera are combined into a left-right wide-view-angle photo or video in the background. When two left and right users use different front-facing cameras to shoot simultaneously, the self-shooting full-screen preview and the shooting picture of the left and right users can be displayed on the display screen simultaneously, the voice data of the left and right users are recorded, the user voice input camera deflection control signal is recognized, the corresponding front-facing camera deflects at a certain angle, the preview and shooting angle of view is adjusted, and the users at the left and right corresponding visual angles only see the required picture and cannot generate interference on the user picture at the other visual angle. In addition, after the shooting is finished, the data shot by the two users can be synthesized to generate a large-view-angle photo or video. By adopting the mode, different users can see two full-screen self-shooting pictures in the self-shooting process, the two full-screen self-shooting pictures cannot influence each other, the front cameras corresponding to the different users can be controlled to carry out self-shooting respectively, and the output self-shooting data is combined into a large-viewing-angle photo or video.
