The number of cameras started in multi-lens shooting of the electronic equipment can be N, N is more than or equal to 2 and less than or equal to M, and N is a positive integer.

In the embodiment of the present application, the type of the camera 293 may be differentiated according to the hardware configuration and the physical location. For example, the plurality of cameras included in the camera 293 may be disposed on the front and back sides of the electronic device, the camera disposed on the display screen 294 of the electronic device may be referred to as a front camera, and the camera disposed on the rear cover of the electronic device may be referred to as a rear camera; for example, cameras having different focal lengths and different viewing angles, which are included in the camera 293, may be referred to as wide-angle cameras, and cameras having a long focal length and a small viewing angle may be referred to as normal cameras. The content of the images shot by different cameras is different in that: the front camera is used for shooting scenes facing the front surface of the electronic equipment, and the rear camera is used for shooting scenes facing the back surface of the electronic equipment; the wide-angle camera can shoot scenes with larger area in a shorter shooting distance range, and the scenes shot at the same shooting distance are smaller than the images of the scenes shot by using the common lens in the picture. The focal length and the visual angle are relative concepts, and are not limited by specific parameters, so that the wide-angle camera and the common camera are also relative concepts, and can be distinguished according to physical parameters such as the focal length, the visual angle and the like.

Particularly, in the embodiment of the present application, the camera 293 at least includes a camera with a time of flight (TOF) 3D sensing module or a structured light (structured light) 3D sensing module, and the camera acquires 3D data of an object in a captured image, so that the processor 210 can identify an operation instruction corresponding to a space gesture of a user according to the 3D data of the object.

The camera for acquiring the 3D data of the object can be an independent low-power-consumption camera, and can also be other common front-mounted cameras or rear-mounted cameras, wherein the common front-mounted cameras or rear-mounted cameras support a low-power-consumption mode, when the low-power-consumption camera works or the common front-mounted cameras or rear-mounted cameras work in the low-power-consumption mode, the frame rate of the camera is lower than that of the common camera working in a non-low-power-consumption mode, and the output image is in a black-and-white format. A typical camera may output 30 frames of images, 60 frames of images, 90 frames of images, 240 frames of images for 1 second, but the low power consumption camera may output, for example, 2.5 frames of images for 1 second when the typical front camera or the rear camera operates in a low power consumption mode, and may switch to output 10 frames of images for 1 second when the camera captures the first image representing the same space gesture, so as to accurately recognize an operation instruction corresponding to the space gesture through continuous multiple image recognition. Meanwhile, compared with the common camera, the power consumption is reduced when the camera works in a low power consumption mode.

Fig. 1B is a software structural block diagram of an electronic device according to an embodiment of the present application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 1B, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 1B, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the electronic device in software and hardware during shooting is illustrated in connection with capturing a photo scene.

When the touch sensor receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video through a camera 293. In the embodiment of the present application, the touch operation received by the touch sensor may be replaced by an operation in which the camera 293 captures a blank gesture input by the user. Specifically, when the camera 293 shoots the operation of the air-stop gesture, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the space gesture operation into the original input event (including the image of the space gesture, the timestamp of the space gesture operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies an operation corresponding to the input event. Taking the operation of switching the shooting mode as an example, the camera application calls the interface of the application framework layer, and further starts other camera drivers by calling the kernel layer, so that the camera application switches to the other cameras 293 to capture still images or videos.

Next, the specific content of the guided use method of the blank gesture provided by the application will be described with reference to the accompanying drawings.

The electronic equipment can pop up the guide popup window of the blank gesture when entering the multi-mirror video for the first time, and display the using method of the blank gesture to a user. The electronic device can also pop up a guide popup window of the blank gesture when the time difference between the last time the blank gesture is used by the user and the current time is larger than the first preset time and the user is detected to have the requirement of using the blank gesture, and display a using method of the blank gesture to the user. The following will describe the process of ejecting the guided missile window by the electronic device in the two scenarios respectively with reference to the accompanying drawings.

Referring to fig. 2A-2B, a process of the electronic device first entering a multi-mirror video is shown.

As shown in fig. 2A, the handset may display a main interface 301. The main interface 301 may include an icon 302 of a camera application. The handset may receive an operation of clicking on the icon 302 by the user, and in response to the operation, as shown in fig. 2B, the handset may open the camera application and display a shooting preview interface 303 of the camera application. It can be understood that the camera application is an application for capturing an image on an electronic device such as a smart phone, a tablet computer, etc., and may be a system application or a third party application, and the name of the application is not limited by the present application. That is, the user may click on the icon 302 of the camera application to open the photographing preview interface 303 of the camera application. Without being limited thereto, the user may also invoke the camera application to open the shooting preview interface 303 in other applications, such as the user clicking on a shooting control in a social class application to open the shooting preview interface 303. The social application can support the user to share the shot pictures or videos with other people.

It should be noted that, the shooting preview interface 303 may be a user interface of a default shooting mode of the camera application, for example, may be a user interface provided when the camera application is in a front shooting mode. It will be appreciated that the default shooting mode may be other, such as a rear shooting mode, a front-rear shooting mode, and the like. Alternatively, the camera application may have a memory function, and the shooting preview interface 303 may be a user interface of a shooting mode in which the camera application is in when the camera application exits last time.

Fig. 2B illustrates an example of the shooting preview interface 303 as a shooting preview interface corresponding to when the camera application is in the front shooting mode. As shown in fig. 2B, the shot preview interface 303 may include a preview image 304 shot mode option 305, a flash control, a shutter control, and the like. The preview image 304 is an image captured by a front camera among the plurality of cameras 293. It should be noted that, the electronic device may refresh the image displayed in the shooting preview interface 303 (i.e., the preview image 304) in real time, so that the user previews the image currently shot by the camera 293. The shooting mode option 305 is used to provide a plurality of shooting modes for selection by the user. The plurality of photographing modes may include: photograph 305a, video 305b, multi-mirror video 305c, real-time blurring, panoramic, etc. The electronic device may receive an operation of the user's left/right slide the photographing mode option 305, and in response to the operation, the electronic device may turn on the photographing mode selected by the user. Note that, not limited to the one shown in fig. 2B, more or fewer options than those shown in fig. 2B may be displayed in the shooting mode option 305.

The photographing mode corresponding to the photographing 305a, i.e. the commonly used single-lens photographing, may include a front photographing mode, a rear photographing mode, and the like. That is, when the photograph 305a is selected, the electronic device may take a photograph through the front camera or the rear camera. For specific description of the front shooting mode and the rear shooting mode, please refer to the foregoing, and the description is omitted herein.

The shooting modes corresponding to the multi-mirror video 305c may include multi-mirror shooting and single-mirror shooting. That is, when the multi-lens video 305c is selected, the electronic apparatus can perform single-lens shooting through one camera or multi-lens shooting through a plurality of cameras. For a specific description of the multi-shot image, reference may be made to the foregoing detailed description, which is not repeated herein.

As shown in fig. 2B, the photo 305a is in a selected state. That is, the electronic device is currently in a photographing mode. If the user wishes to turn on the multi-mirror recording mode, he/she can slide left through the capture mode option 305 and select the multi-mirror recording 305c. When detecting the user's left-hand slide of the photographing mode option 305 and selecting the operation of the multi-mirror video 305c, the electronic device may turn on the multi-mirror video mode and display a photographing preview interface 401 as shown in fig. 3A.

As shown in fig. 3A, after entering the multi-mirror video recording mode, the electronic device may display a shooting preview interface 401. The shooting preview interface 401 includes an image 401a (which may also be referred to as a second image), an image 401b (which may also be referred to as a first image), a blank mirror change control 402, a teaching guide control 403, a prompt message 404, a setting control 405, and a shooting mode switching control 406. The image 401a is an image acquired by a rear camera in real time, the image 401b is an image acquired by a front camera in real time, and the image 401a and the image 401b are spliced up and down due to the fact that the electronic equipment is arranged vertically. Specifically, the first image is located in a first area of the shooting preview interface, the second image is located in a second area of the shooting preview interface, and the first area and the second area are not overlapped. Illustratively, the first region may be the region of image 401b in fig. 3A, and the second region may be the region of image 401a in fig. 3A.

In the application, when the electronic device enters the multi-mirror video recording mode for the first time, the front camera and the rear camera are started by default, and the display mode of the image is a splicing mode by default. However, in other embodiments, the default on camera may be two rear cameras, a front camera, or a rear camera. The display method of the image is not limited to the stitching method, and may be a picture-in-picture method or the like, and is not particularly limited herein. Or, the camera application may have a memory function, and after the electronic device enters the multi-mirror video mode, the electronic device may start the camera that is working when the camera application exits from the multi-mirror video mode last time, and display the camera in the last display mode.

Wherein, the blank mirror changing control 402 can be used for a user to quickly start/stop the blank mirror changing function. After the function of changing the mirror at intervals is started, a user can control the electronic equipment through the intervals. It should be noted that, after the electronic device enters the multi-mirror video recording mode, the function of changing the mirror with a space can be started by default. Thus, the blank mirror control 402 is in an on state (which may also be referred to as a first state) for indicating that the blank mirror function has been turned on. Of course, the space-saving mirror changing function can also be turned off. For example, in response to detecting a touch operation by a user on the blank mirror control 402, the electronic device may turn off the blank mirror function. At this point, the blank mirror control 402 is in an off state (also referred to as a second state) for indicating that the blank mirror function has been turned off.

The teaching guidance control 403 (also referred to as a first control) may be used to guide a user to learn a blank gesture of blank changing a mirror, such as a blank gesture to open a recording, a gesture to switch a double mirror and a single mirror, a gesture to open/close a picture-in-picture, a gesture to exchange a front and rear lens, a gesture to end a recording, and the like. Note that, the teaching guidance control 403 is associated with a space-apart mirror change function: when the blank mirror change function is turned on (or the blank mirror change control 402 is in an on state), the shooting preview interface 401 may display the teaching guide control 403; when the blank mirror function is turned off (or the blank mirror control 402 is in the off state), the shooting preview interface 401 may hide (and may be understood as not displaying) the teaching guide control 403. It should be noted that, when the electronic device starts recording, the teaching guide control 403 may also be hidden.

The prompt information 404 (also referred to as a guidance prompt) is disposed at a preset position of the teaching guidance control 403 (for example, disposed on the left side of the teaching guidance control 403 and pointing to the teaching guidance control 403), and is used for reminding the user to click the teaching guidance control 403 to view the teaching of the alternate mirror gesture. For example, the prompt 404 may be a "click viewable" alternate mirror "gesture.

The setting control 405 may be used to adjust parameters of the photographed picture (e.g., resolution, picture scale, etc.), turn on or off some of the ways to photograph (e.g., alternate mirror, time photographing, smile snapshot, voice-controlled photographing, etc.), etc. Specifically, the electronic device may receive an operation in which the user clicks the setting control 405, and in response to the operation, the electronic device may display a setting interface 405a as illustrated in fig. 3B. The setup interface 405a may include options such as alternate mirror 405b, photo scale, voice-controlled photographing, etc. The alternate mirror 405b may turn on or off the alternate mirror function. Note that, the on-off state of the blank mirror 405b in the setting interface 405a is linked with the on-off state of the blank mirror control 402 in the shooting preview interface 401, and the on-off state of the blank mirror 405b is consistent with the on-off state of the blank mirror control 402. That is, if the blank mirror 405b is switched from the on/off state to the off/on state, the blank mirror control 402 is also switched from the on/off state to the off/on state, and vice versa.

The shooting mode switch control 406 may be used to provide a variety of shooting modes for selection by a user, such as a front-back shooting mode, a back-back shooting mode, a picture-in-picture shooting mode, a front shooting mode, a back shooting mode, and so on.

It should be noted that the process of re-scheduling the multi-mirror video from the electronic device may be consistent with the process shown in fig. 2A-2B. The difference is that after the electronic device has entered the video recording, the prompt message 404 is no longer displayed on the shooting preview interface.

If the user wishes to view the instructional guide for the blank gesture, the instructional guide control 403 may be clicked. As shown in fig. 4, the electronic device may receive an operation by which the user clicks on the tutorial guide control 403, in response to which the electronic device may display a guide pop 407 (also referred to as a second pop) as shown in fig. 5A. The guided missile window 407 can be used to show the manner of use of the blank gesture and related ancillary interpretation. Specifically, the guided pop-up window 407 may include an animation display region 407a (may also be referred to as a first display region), a text prompt region 407b (may also be referred to as a second display region), and a confirmation option 407c. The animation display region 407a is used for displaying a plurality of guiding videos so as to display the using method and effect of the air-stop gesture. In one design, the active display 407a may be presented in an animated manner that is more vivid and understandable, which helps the user to quickly understand and learn the space-apart gestures. The content displayed in the text prompt area 407b matches the content displayed in the active display area 407a, and can be used for assisting in explaining the function of the blank gesture being displayed in the active display area 407a and the using method of the blank gesture.

As shown in fig. 5A to 5C, the animation display region 407a may display a guide animation recorded with a gap open.

Specifically, as shown in fig. 5A, in the animation display region 407a, the electronic device is in the front-rear shooting mode. The electronic device may display an image 409a captured by the rear camera and an image 409b captured by the front camera on the capture preview interface 408. The electronic device may also display a blank mirror icon 410 upon recognition of the "hand up" gesture. As shown in fig. 5B, when the electronic device continuously detects the gesture of holding the "lift hand", the time progress bar of the spaced mirror icon 410 may be gradually filled, and after a first preset time (for example, 2 seconds), the photographing preview interface 408 shown in fig. 5C may be displayed. Compared to the shooting preview interface 408 shown in fig. 5A, the shooting preview interface 408 shown in fig. 5C is a shooting preview interface after the electronic device is turned on to a recording state.

Correspondingly, the text prompting area 407b may display "open record at intervals", and wait 2 seconds after the user lifts the icon 410 (a specific icon is shown in the figure) for changing the mirror at intervals, so as to assist the user in understanding how to open record using the interval gesture.

As shown in fig. 6A to 6F, the animation display region 407a may also display a guide animation that switches the double mirror and the single mirror at intervals.

Fig. 6A to 6C show a guide animation in which the electronic device is switched from a double mirror to a single mirror.

As shown in fig. 6A, in the animation display region 407a, the electronic device is in the front-rear shooting mode. The electronic device may display an image 409a captured by the rear camera and an image 409b captured by the front camera on the capture preview interface 408. Where image 409a is located to the left of the capture preview interface 408 and image 409b is located to the right of the capture preview interface 408. As also shown in fig. 6A, the electronic device may display a blank mirror icon 410 upon recognition of a "hand up" gesture. As shown in fig. 6B, after the electronic device detects the gesture of "palm sliding from right to left", the front-back shooting mode may be switched to the front-side shooting mode, and a shooting preview interface 408 shown in fig. 6C is displayed, where the shooting preview interface 408 includes an image 409B. During the switching process, the image 409a may be correspondingly moved from right to left and gradually reduced in display area according to the gesture from right to left, and finally disappear from the shooting preview interface 408, while the image 409b correspondingly moved from right to left and gradually increased in display area, and finally fills the whole shooting preview interface 408.

Fig. 6D-6F show a boot animation of the electronic device switching from a single mirror to a double mirror.

As shown in fig. 6D, the electronic device, while in the front-facing shooting mode, may display an image 409b shot by the front-facing camera in the shooting preview interface 408. In addition, the electronic device may also display a blank mirror icon 410 after recognizing the "hand up" gesture. As shown in fig. 6E, the electronic device may switch the photographing mode from the front photographing mode to the front-rear photographing mode after detecting the gesture of "palm slide from left to right", and display the photographing preview interface 408 as shown in fig. 6F. In fig. 6F, the electronic device displays both the image 409a captured by the rear camera and the image 409b captured by the front camera. The display forms of the image 409a and the image 408b are in a form of left-right stitching, and the image 409a may be displayed on the left side of the shooting preview interface 408 according to the gradually increasing display area corresponding to the gesture of the palm sliding from left to right, and the image 408b may be displayed on the right side of the shooting preview interface 408 according to the gradually decreasing display area corresponding to the movement from left to right.

Correspondingly, in fig. 6A-6F, the text prompting area 407b may display "switch between double and single mirrors at intervals", and when the screen is shifted horizontally by the hand after the screen is shifted by the interval of the user's hand by the screen switching icon 410, the left screen is pushed by the left slide and the right screen is pushed by the right slide. (when the screen is erected, the screen is pushed away by left sliding, the screen is pushed away by right sliding) ", and the screen is used for assisting a user in understanding how to switch between a single mirror and a double mirror by using a space gesture.

As shown in fig. 7A to 7C, the animation display region 407A may also display a guide animation that turns on/off the pip at intervals.

As shown in fig. 7A, the electronic device is in the rear-end shooting mode, and an image 409a shot by the rear camera is displayed in the shooting preview interface 408. As also shown in fig. 7A, the electronic device may display a blank mirror icon 410 upon recognition of a "hand up" gesture. As shown in fig. 7B, the electronic device may, after recognizing the gesture of "lift hand and make a fist," turn on the picture-in-picture mode and display a shoot preview interface 408 as shown in fig. 7C. The photographing preview interface 408 shown in fig. 7C displays an image 409a and an image 409b at the same time. Wherein image 409a is still displayed in the entire display area of the photographing preview interface 408, and image 409b is superimposed on this image 409a.

In addition, the animation display region 407A may also display the inverse of fig. 7A-7C. That is, the electronic device may display the photographing preview interface 408 shown in fig. 7B after detecting a gesture of "lift hand" in the photographing preview interface 408 shown in fig. 7C. Then, after a gesture of "lift hand and make a fist" is detected in the shooting preview interface 408 shown in fig. 7B, the shooting preview interface 408 shown in fig. 7A is displayed. In other words, the user can turn on or off the picture-in-picture by this "lift hand and make a fist" gesture.

In fig. 7A-7C, the text prompting area 407b may display "open/close the pip at intervals" to assist the user in understanding how to open/close the pip using the spaced gesture by holding a fist after the spaced gesture icon 408 appears.

In one possible design, before the electronic device displays the shooting preview interface 408 shown in fig. 7A, the electronic device may also display the shooting preview interface 408 shown in fig. 7D, where the shooting preview interface 408 is an interface displayed by the electronic device before the gesture of "lift hand" is recognized. The capture preview interface 408 may display a prompt 411, where the prompt 411 is used to prompt the user, and the electronic device may use the front camera to recognize the blank gesture when in the rear capture mode, so as to avoid the user from feeling that the privacy is violated. In the embodiment of the present application, the prompt 411 may be an icon. In other embodiments, the prompt 411 may be in the form of text or a combination of text and icons. It should be noted that, instead of combining the animation of switching the double mirror and the single mirror at intervals, the scene shown in fig. 7D may be displayed as a single guide animation in the animation display region 407 a.

As shown in fig. 8A to 8C, the animation display region 407a may also display a guide animation of the lens before and after the gap switch.

As shown in fig. 8A, the electronic device is in the rear-end shooting mode, and an image 409a shot by the rear camera is displayed in the shooting preview interface 408. The electronic device may display the blank mirror icon 410 after a "hand up" gesture is recognized. As shown in fig. 8B, the electronic device may switch the photographing mode from the rear photographing mode to the front photographing mode after recognizing the gesture of "flip from palm to back of hand", and display the photographing preview interface 408 as shown in fig. 7C. The shooting preview interface 408 displays an image 409b shot by the front camera.

In fig. 8A-8C, the text prompting area 407b may display "before and after the shot is switched at intervals", and after the hand is lifted to have the gesture icon 408 at intervals, the hand is turned from the palm to the back of the hand "to assist the user in understanding how to use the shot before and after the shot is switched at intervals.

In the embodiment of the present application, before the electronic device displays the shooting preview interface 408 shown in fig. 8A, the electronic device may also display the shooting preview interface 408 shown in fig. 7D, and the specific content thereof is referred to the foregoing and is not described herein.

As shown in fig. 9A to 9C, the animation display region 407a may also display a guide animation of the end of the gap recording.

As shown in fig. 9A, the electronic device is in the front-back shooting mode, and an image 409A shot by the rear camera and an image 409b shot by the front camera are displayed in the shooting preview interface 408, and the image 409A is stitched with the image 409b from side to side. The electronic device may display a blank mirror icon 410 upon recognition of a hand-lifting gesture. As shown in fig. 9B, in the scenario shown in fig. 9A, the electronic device may display a shooting preview interface 408 shown in fig. 9C after recognizing the gesture of "OK". Compared to the shooting preview interface 408 shown in fig. 9A, the shooting preview interface 408 shown in fig. 9C is a shooting preview interface after the electronic device ends the recording state.

In fig. 9A-9C, the text prompting area 407b may display "end recording at a space", and after the space gesture icon 408 appears on the hand, the thumb and the index finger are connected to form a circle, and the other fingers are naturally curved "to assist the user in understanding how to end recording using the space gesture.

In the guide pop-up window 407, the animation display region 407a can automatically play the guide animation by playing and circularly playing the record with the interval on, switching the double and single mirrors with the interval on/off, switching the picture-in-picture with the interval on/off, switching the front and rear shots with the interval on, and ending the record with the interval on. It should be noted that, the playing sequence does not have to be played according to the sequence of opening recording at intervals, switching the double mirrors and the single mirrors at intervals, opening/closing the picture-in-picture at intervals, switching the front and rear lenses at intervals, and ending recording at intervals, but other playing sequences may exist, and the method is not particularly limited herein.

It should be noted that the above-mentioned blank gesture is only an example, and the blank gesture may be other gesture, for example, a "winning" gesture, a "waving hand from left to right", and so on.

In the embodiment of the present application, the electronic device may further receive an operation of sliding the guide window 407 by the user, and in response to the operation, the electronic device may switch the guide animation being played in the animation display region 407a and the prompt information displayed in the text display region 407 b. For example, if the electronic device sequentially plays the corresponding guide animation according to the sequence of the open record of the space, the double mirrors and the single mirrors switched by the space, the picture-in-picture switched by the space, the lenses before and after the switch by the space, and the record of the end of the space. Then, as shown in fig. 10, the electronic device may display the guide animation and the related text explanation of the shots before and after the blank switch in the guide pop-up window 407. The electronic device may receive an operation that the user left-slides the guide popup 407, and in response to the operation, as shown in fig. 9A, the electronic device switches the guide animation displayed in the guide popup 407 to a guide animation recorded at the end of the spaced apart.

It should be noted that, after the electronic device receives the operation of manually switching the animation by the user, the electronic device does not automatically play the plurality of guide animations. That is, once the user manually switches the animation, the electronic device can switch the guide animation played by the guide window 407 again only after receiving the operation of switching the animation again by the user.

The confirmation option 407c is used for the user to end the teaching guidance in advance. For example, the confirmation option 407c may be "known". For example, as shown in fig. 11A, the electronic device may receive an operation in which the user clicks the confirm option 407c, in response to which the electronic device closes the lead window 407, and displays the photographing preview interface 401 as shown in fig. 11B. The shooting preview interface 401 is similar to the shooting preview interface 401 shown in fig. 4, except that: the capture preview interface 401 no longer displays the prompt 404. It should be noted that, when the user plays any one of the guide animations, clicking the confirmation option 407c causes the electronic device to close the guide window 407.

It can be seen that the electronic device can automatically play a plurality of guide animations before the electronic device does not receive the instruction for switching animations or the instruction for ending the guide. And after the electronic equipment receives the instruction for switching the animation, the electronic equipment does not automatically carousel a plurality of guide animations. After receiving the instruction for ending the guidance, the electronic device can end the teaching guidance.

In the embodiment of the present application, if the electronic device does not detect that the user clicks the teaching guide control 403, and the user does not use the blank space gesture, the electronic device may actively display the guide window 407 when entering the multi-mirror video mode for the second time, and actively guide the user to learn the blank space gesture. The description of the guide pop 407 refers to the relevant content in the foregoing, and is not repeated herein. In an alternative embodiment, the electronic device may detect whether the shooting mode was switched in response to the first camera detecting a blank gesture. If the electronic device has switched the capture mode in response to the first camera detecting the over-air gesture, the user may be considered to use the over-air gesture. If the electronic device does not switch the shooting mode in response to the first camera detecting the blank gesture, the user may be considered to not use the blank gesture.

That is, the electronic device may alert the user to view the teaching guidance regarding the blank gesture when entering the multi-mirror video mode for the first time. If the user does not view the teaching guide when the electronic device enters the multi-mirror video mode for the first time (which can be understood as that the electronic device does not detect that the user clicks the teaching guide control 403), the teaching guide about the blank gesture can be automatically played when the electronic device enters the multi-mirror video mode for the second time. Through guiding the user to watch the teaching guide about the blank gesture many times, can promote the user and look over the probability that teaching was guided, make the user learn the blank gesture as far as possible, promote human-computer interaction efficiency.

The guided missile window 407 is displayed when the electronic device first enters a multi-mirror video, and is mainly aimed at guiding the user to learn how to use the blank gesture. However, after learning, the user may not actually use the space-saving gesture frequently. Thus, the electronic device may also guide the user to use the space-apart gesture at an appropriate time.

Specifically, the electronic device may pop up the guide pop window of the blank gesture when the time difference between the time when the blank gesture is detected to be used last time by the user (the time when the electronic device switches the shooting mode in response to the first camera detecting the blank gesture or the first time) and the current time is greater than the first preset time and the user is detected to have a requirement of using the blank gesture, and display a using method of the blank gesture to the user. The electronic equipment is in a recording state under the multi-mirror video recording.

If the time difference between the last time the user used the blank gesture and the current time is greater than the first preset time, the user can be considered to use the blank gesture once, but the user may not use the blank gesture again for a long time due to forgetting to use the blank gesture or forgetting the blank gesture. Under the condition, the user is reminded to use the space-isolation gesture, and influence on user experience caused by frequent reminding of the user to use the space-isolation gesture can be avoided. The blank gesture may be any one of a gesture of blank opening and recording, a gesture of blank switching a double mirror and a single mirror, a gesture of blank opening/closing a picture-in-picture, a gesture of a lens before and after blank switching, and a gesture of blank ending and recording.

In an alternative design, if the electronic device detects that the distance between the user in the front picture and the display screen is greater than or equal to the preset distance within the second preset time after the electronic device is started and recorded, the electronic device can be considered to detect that the user has a need to use the space gesture.

The user in the front-facing picture can be understood as the user photographed by the front-facing camera. The distance between the user and the display screen in the front-facing screen being greater than or equal to the preset distance can be understood that the shooting preview interface of the electronic device is displaying the image shot by the front-facing camera, and the distance between the user and the display screen is greater than or equal to the preset distance. The preset distance may refer to a distance at which the user cannot touch the display screen without reducing the distance between the user and the display screen. For example, the preset distance may be a distance of 60 cm from the display screen when the user records using the selfie stick-holding electronic device.

It can be appreciated that, in the above scenario, if the user switches the shooting mode by touching the shooting mode switching control 406 on the display screen, the view of the front camera is easily affected, so that the quality of the video is affected. Thus, in this case, the user may be considered to have a need to use the air-break gesture, which may be guided.

For example, the electronic device may display the shooting preview interface 401 shown in fig. 12 when detecting that the distance between the user and the display screen in the front-end screen is greater than or equal to the preset distance in the second preset time after the video recording is started. The shooting preview interface 401 is similar to the shooting preview interface 401 shown in fig. 11B, except that: the image 401a and the image 401b in the shooting preview interface 401 are spliced in the left-right direction because the electronic device is placed horizontally. The shot preview interface 401 further includes a guided missile window 412 (also referred to as a first missile window). The guide pop-up window 412 is used to present a blank gesture to guide the user to use the blank gesture. For example, the guide pop-up window 412 may display a gesture for switching the double and single mirrors on and off, a gesture for switching the front and rear lenses on and off, and a gesture for switching the picture-in-picture on and off on a screen.

In an alternative design, if the electronic device detects that the first image is reduced in duty ratio within a second preset time after the electronic device starts recording, where the first image is the area duty ratio of the face area in the first image, it is considered that the user is detected that there is a need to use the space gesture, and the electronic device may display the guide pop window 412 as shown in fig. 12.

In an alternative design, the electronic device may be considered to have detected that a user is in need of using a space-apart gesture when the electronic device is connected to the selfie stick.

The electronic equipment can be connected with the self-timer stick through earphone holes, bluetooth, WIFI and the like. For example, after the electronic device turns on the bluetooth function, a pairing request sent from the camera stick may be received. The pairing request may carry the device name, media access control (media access control, mac) address, and device type identification of the selfie stick. The device type identifier indicates that the device type of the sender of the pairing request is a self-timer stick. Therefore, after the electronic equipment is paired with and connected with the self-timer stick, the self-timer stick can be confirmed to be connected according to the equipment type identifier.

When the electronic device is connected to the selfie stick, it can be considered that the user needs to remotely shoot, in this case, if the user switches shooting modes by touching the shooting mode switching control 406 on the display screen, the framing of the front camera will be affected, so that the quality of the video is affected. Thus, in this case, the user may be considered to have a need to use the air-break gesture, which may be guided.

When the electronic device is connected to the selfie stick, a shooting preview interface 401 and a guide pop-up window 412 as shown in fig. 12 may be displayed. The specific description of the shooting preview interface 401 is referred to above, and is not repeated here.

It should be noted that, when the electronic device is in the recording state, if the connection of the selfie stick is detected, the electronic device may display the guide popup window 412 as shown in fig. 12. In fact, when the electronic device connects to the selfie stick, in response to receiving the first operation of the user, the electronic device starts recording the video, and the electronic device displays the guided missile window 412 on the shooting preview interface 401. That is, the electronic device may first connect to the selfie stick and then display the first pop-up window after the video recording is started. In other words, as long as the time difference between the time when the user last used the space gesture (also referred to as the first time) and the current time is greater than the first preset time, the electronic device can display the guided missile window 412 if the two conditions that the electronic device is recording video and connecting the selfie stick are satisfied.

In an alternative design, when the electronic device detects that the user switches shooting modes on the display screen, the electronic device may be considered to have a need to use a blank gesture.

Specifically, as shown in fig. 13A, the electronic device may receive an operation in which the user clicks the shooting mode switching control 406 (may also be referred to as a second control), and in response to the operation, the electronic device may display a shooting preview interface 401 as shown in fig. 13B. As shown in fig. 13B, the shooting preview interface 401 may include a guide window 412 and a shooting mode selection area 413 (which may also be referred to as a third shot window). Wherein reference is made to the contents of guided missile window 412, and the description thereof is omitted herein. The shooting mode selection area 413 may display preview interfaces of multiple shooting modes, such as a preview interface 413a of a front shooting mode, a preview interface 413b of a rear shooting mode, a preview interface 413c of a picture-in-picture shooting mode, a preview interface 413d of a rear shooting mode, and a preview interface 413e of a front and rear shooting mode.

In summary, when the electronic device is in the recording state of the multi-mirror video, if the time difference between the time when the user last uses the blank gesture and the current time is detected to be greater than the first preset time, and the distance between the user in the front-mounted picture and the display screen is detected to be greater than or equal to the preset distance within the second preset time after the recording is started, the electronic device may display the guide popup window 412 as shown in fig. 12. When the electronic device is in the recording state of the multi-mirror video, if the time difference between the time when the user last uses the blank gesture and the current time is detected to be greater than the first preset time and the electronic device is connected to the selfie stick, the electronic device may display the guide popup window 412 as shown in fig. 12. When the electronic device is in the recording state of the multi-mirror video, if the time difference between the time when the user last uses the blank gesture and the current time is detected to be greater than the first preset time and the user is detected to switch the shooting mode on the display screen, the electronic device may display the guide popup window 412 as shown in fig. 13B.

The above description is only for illustrating the guiding method of the blank gesture when the electronic device is in the front-back shooting mode. In practice, the electronic device may be in any shooting mode under the multi-mirror video recording, for example, a picture-in-picture shooting mode, a front shooting mode, a rear shooting mode, and the like, which is not particularly limited herein.

Therefore, the guide using method of the space-apart gesture provided by the application can remind a user to learn the space-apart gesture when the electronic equipment enters the multi-mirror video for the first time. Particularly, the electronic device can pop up the guide popup window of the air-separation gesture when the time difference between the last time the air-separation gesture is used by the user and the current time is larger than the first preset time and the user is detected to have the requirement of using the air-separation gesture, the using method of the air-separation gesture is displayed for the user, the possibility of using the air-separation gesture by the user is increased, and the man-machine interaction efficiency is improved.
