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 camera, a second 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 data acquired by the first camera and second data acquired by the second camera.
Wherein the first data and the second data are image data or video data. Specifically, the mobile terminal comprises a backlight source and a display panel, wherein the backlight source comprises at least two light source assemblies, and different light source assemblies respectively correspond to first data collected by a first camera and second data collected by a second camera. Specifically, when two users, namely a left user and a right user, share and shoot simultaneously, the left user A located in the visual range of the first full-screen picture collects first image or video data through the first camera, and the right user B located in the visual range of the second full-screen picture collects second image or video data through the second camera.
Step 302: and controlling the display screen to alternately display the first data and the second data according to a preset display frame rate.
When a user starts screen sharing, the first data or the second data corresponding to each light source assembly are alternately displayed according to a preset display frame rate, so that the effect that different users share the screen at the same time is achieved. For example, the first light source component corresponds to the first camera to control the display screen to display the first data for the left user a in the visible range of the first full screen, and the second light source component corresponds to the second camera to control the display screen to display the second data for the right user B in the visible range of the second full screen.
Based on the structure of the display screen, the embodiment of the invention can realize that the images of two full screens can be watched in different angle ranges, specifically, the first data collected by the first camera can be watched in the visual range of the first full screen image, and the second data collected by the second camera can be watched in the visual range of the second full screen image, so that two users can see the images of the two full screens, the two full screens cannot mutually influence, and the use experience of the users can be favorably improved.
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 first 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 data; and after the interval preset time interval, circularly executing the steps of opening the first light source component, closing the second light source component, controlling the display screen to display the first data to the interval preset time interval, closing the first light source component, simultaneously opening the second light source component, and controlling the display screen to display the second data until the screen sharing function is detected to be closed, or until the first camera or the second 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 turned on simultaneously, at this time, the mobile terminal detects the on state of the screen sharing function, and if the on state is detected to indicate that the screen sharing function is turned on and both the first camera and the second camera are turned on, the first data collected by the first camera and the second data collected by the second camera are acquired, that is, step 301 is executed. If the on state is detected to indicate that the screen sharing function is turned off or the first camera or the second camera is turned 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 data collected by the first camera, and at this time, only the left user a can see the frame display content. (2) After a preset time interval, the right LED lamp is turned off, the left LED lamp is turned on at the same time, a second frame of the display panel displays first frame display content of second data collected by the second camera, and only the right user B can see the picture display content. (3) After a preset time interval, the right LED lamp is turned on, the left LED lamp is turned off at the same time, the third frame of the display panel displays the second frame display content of the first data collected by the first camera, and only the left user A can see the picture display content. (4) After a 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 data collected by the second camera, and only the right user B can see the picture display content.
And alternately displaying the data pictures acquired by the first camera and the second camera according to the method, wherein when the preset time interval is small enough, namely the preset display frame rate is fast enough, the users at the left side and the right side can watch coherent 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 data picture frames that the left and right users want to shoot, so that the left and right users can watch respective required pictures at the same time and can only watch the respective required pictures, thereby improving user experience.
Further, after alternately displaying the first data collected by the first camera and the second data collected by the second 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 camera and/or the second camera to execute shooting operation according to the shooting control instruction. Wherein the shooting control instruction is associated with the rotation angle and the rotation direction of the first camera and/or the second camera. Specifically, the first camera and the second camera can be respectively deviated from the view finding direction of the corresponding user according to a certain angle according to the shooting control instruction, the deflection can be controlled by the angles of the two cameras, the left camera can be deviated from the view finding direction of the left user A, and the right camera can be deviated from the view finding direction of the right user B.
Specifically, as shown in fig. 5, the first camera 5 and the second camera 6 are both rear cameras with adjustable shooting angles, that is, both the first camera 5 and the second camera 6 can rotate, and the mobile terminal further includes at least one front camera 7. Specifically, the step of detecting whether the photographing control instruction is received includes: and controlling at least one front camera to detect the control action. If the shooting control instruction is detected, the step of controlling the first camera and/or the second camera to execute the shooting operation according to the shooting control instruction comprises the following steps: and if the control action is detected, controlling the first camera and/or the second camera to execute shooting operation according to the control action.
Specifically, as shown in fig. 6, the at least one front camera 7 includes a first front camera 71 and a second front camera 72. The step of controlling at least one front camera to detect the control action comprises the following steps: and respectively controlling the first front camera and the second front camera to perform control action detection. If the control action is detected, the step of controlling the first camera and/or the second camera to execute the shooting operation according to the control action 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 camera to carry out rotary shooting 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 camera to carry out rotary shooting according to the second control action. That is, the control action is captured by the front camera, and the control action comprises: at least one of a gesture control action, a head swing control action, and a finger pointing control action. If the head acts (if the camera rotates a certain angle leftwards when the head is turned leftwards, and the head is lifted upwards to rotate a certain angle upwards), gesture recognition (the camera rotates a certain angle rightwards when the fingers rotate rightwards, and the camera rotates a certain angle upwards when the fingers rotate upwards) and the like are carried out. And if the first front camera detects that the user twists the head leftwards in the visual range of the first full-screen picture, controlling the first 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 shooting picture of the user. When a plurality of users shoot simultaneously, whether the users click to enter the shared shooting function is judged, if not, the LEDs on the two sides are continuously controlled to be simultaneously started, and data pictures collected by the camera are displayed. If the fact that the user clicks to enter the shared shooting function is detected, previews or shooting pictures of the first camera and the second camera (the left camera and the right 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 full-screen previews or shooting pictures required by the user at the same time. When the front camera detects that a user inputs an instruction for rotating the camera, if the head swings up and down and left and right (the detection is carried out through the front camera), when fingers/palms point to the upper, lower, left and right directions, the camera rotates a certain angle respectively corresponding to the upper, lower, left and right directions, the shooting or previewing visual angle is changed, and the deviated angle is recorded.
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 camera and/or the second camera to output image data or video data.
Specifically, as shown in fig. 6, the first camera 5 and the second camera 6 are both rear cameras, and the mobile terminal includes a first front camera 71 and a second front camera 72. The step of detecting a preset action for ending the photographing includes: and respectively controlling the first front camera and the second front camera to carry out preset action detection. If the preset action is detected, the step of controlling the first camera and/or the second camera to output image data or video data comprises the following steps: if the first front-facing camera detects a first preset action in the visible range of the first full-screen picture, controlling the first camera to output image data or video data; and if the second preset action is detected by the second front-facing camera in the visible range of the second full-screen picture, controlling the second camera to output image data or video data. That is to say, when the user performs a photographing or video recording operation, preset actions such as blinking, scissors, smiling photographing and the like are performed, and the current photo or video of the user is cached. For example, when it is detected that the left user a performs a photographing or video recording operation, preset actions such as blinking, scissors, smiling photographing, and the like are performed, and the photo or video of the left user a is cached. When the right user B is detected to be in photographing or video recording operation, preset actions such as blinking, scissors and smiling photographing are executed, and the photos or videos of the right user B are cached.
Further, the step of 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 includes: touch operations on a first shooting button in the first full screen picture and a second shooting button in the second full screen picture are detected respectively. If the preset action is detected, the step of controlling the first camera and/or the second camera to output image data or video data comprises the following steps: if a first touch operation on the first shooting button is detected, controlling the first camera to output image data or video data; and if the second touch operation on the second shooting button is detected, controlling the second camera to output image data or video data. That is, when the user performs a photographing or video recording operation, for example, clicking a video recording or photographing button, the current user's picture or video is cached. For example, when it is detected that the left user a performs a photographing or video recording operation, a preset action such as clicking a video recording or photographing button is executed to cache the picture or video of the left user a. When the right user B is detected to have photographing or video recording operation, preset actions such as clicking a video recording button and a photographing button are executed, and the picture or video of the right user B is cached.
The method further comprises the following steps after the step of controlling the first camera and/or the second 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 camera and the second camera to generate an image; or, video synthesis is carried out on the video data shot by the first camera and the second camera to generate a video. Specifically, according to the recorded deviation angle of the camera, the first data collected by the first camera and the second data collected by the second camera are combined into a left-right wide-angle photo or video in the background. When two users on the left and right sides use different cameras to shoot simultaneously, full-screen preview and shooting pictures corresponding to the two users on the left and right sides can be displayed on a display screen simultaneously, the angle of the camera is adjusted by detecting head rotation, gestures and the like of the corresponding users through the front-facing camera to adjust the shooting angle of view, so that the users at the corresponding left and right angles of view only see the pictures needed by the users and cannot interfere with the pictures of the users at the other angle of view. 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 camera, and second reference voice data associated with the second camera. That is to say, through gathering the speech information of user's input, control first camera and second camera and carry out angle rotation and shoot the operation. For example, if voice information of the left user a is detected, the first camera is controlled to perform angle rotation and shooting; and when the voice information of the right user B is detected, controlling the second camera to rotate in angle and shoot.
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 simultaneously, whether the users click to enter the shared shooting function is judged, if not, the LEDs on the two sides are continuously controlled to be simultaneously started, and data pictures collected by the camera are displayed. If the fact that the user clicks to enter the shared shooting function is detected, previews or shooting pictures of the first camera and the second camera (the left camera and the right 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 full-screen previews or shooting pictures required by the user at the same time. Further, if a shooting control instruction is detected, the step of controlling the first camera and/or the second camera to execute 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 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 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 left camera deflects by certain angles up, down, left and right respectively, and simultaneously records the angle difference of the 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 camera and the first reference voice information and a second incidence relation between the second 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 B to speak, and the voice data of the right user B is recorded by the integrated microphone and matched with the voice data of the right user.
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 camera and/or the second 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.
