That is to say, under the condition that the time difference between the first time and the current time is greater than the first preset time, the electronic device may connect the selfie stick first, and the user may control the electronic device to start recording the video through the selfie stick, the blank gesture, and the control on the shooting preview, and at this time, the electronic device may also display the first popup window on the shooting preview interface.

In a possible implementation manner, the shooting preview interface includes a first control, and the method further includes: responding to the operation of the user on the first control, and displaying a second popup window on a shooting preview interface by the electronic equipment; the electronic equipment circularly plays a plurality of guide videos in the second popup window according to a preset sequence, and each guide video in the guide videos is used for showing a using method of an empty gesture.

Therefore, the electronic equipment can guide the user to use the air gesture in the video recording process, and the electronic equipment can also display the using method of the air gesture through the second pop-up window and guide the user to use the air gesture from multiple aspects.

In one possible implementation, the method further includes: responding to the operation of sliding the second popup to the left by the user, displaying the last guide video adjacent to the first video which is playing on the second popup by the electronic equipment, and stopping the circular playing; or, in response to the operation of the user to slide the second popup to the right, the electronic device displays the next guide video adjacent to the first video in the second popup and stops the loop playing.

That is, the electronic device may automatically and cyclically play the plurality of guide videos on the second pop-up window, or the user may manually select a guide video that the user wants to see.

In a possible implementation manner, the second popup window includes a first display area and a second display area, the first display area is used for playing a plurality of guide videos in a circulating manner, the second display area is used for displaying a plurality of prompt messages corresponding to the plurality of guide videos in a circulating manner, the plurality of guide videos correspond to the plurality of prompt messages one to one, each prompt message is used for explaining a function and a use method of a blank gesture displayed by the corresponding guide video, and the guide video being displayed in the first display area corresponds to the prompt message being displayed in the second display area.

That is, the second pop-up window can display not only the guide video but also prompt information (which may include characters and icons) corresponding to the guide video, which is more beneficial for the user to understand the use method of the air-separating gesture.

In one possible implementation, the second popup comprises a confirmation option, and the method further comprises: and in response to the operation of the user on the confirmation option, the electronic equipment closes the second popup window. That is, the second popup window may be manually closed by the user, and if the user does not click the confirmation option, the electronic device may always display the second popup window.

In one possible implementation, the method further includes: if the electronic equipment detects that the user does not click the first control and does not respond to the first camera to detect the blank gesture and switch the shooting mode, the electronic equipment displays a second popup window on the shooting preview interface.

It can be seen that the first electronic device can confirm whether the user learns the usage of the spaced gesture by detecting whether the user clicks the first control, and confirm whether the user uses the spaced gesture by detecting whether the photographing mode is switched in response to the first camera detecting the spaced gesture. When it is detected that the user does not click on the first control and does not switch the shooting mode in response to the first camera detecting the air-separating gesture, the user is considered to not learn the usage of the air-separating gesture and not use the air-separating gesture, and in this case, the electronic device can automatically pop up the second pop-up window to guide the user to learn to use the air-separating gesture. Further, the electronic device may perform the detection when entering the multi-mirror recording mode for the second time, and automatically pop up the second popup window when the condition is satisfied.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

In the interest of clarity and conciseness in the description of the various embodiments that follows and to facilitate the understanding of those skilled in the art, a brief introduction to related concepts or technologies is first presented.

The shooting preview interface refers to an interface displayed before or during shooting of the electronic equipment and can be used for displaying images acquired by the camera in real time. In addition, the shooting preview interface can also display a plurality of controls, and the plurality of controls can comprise a flash light control for turning on/off a flash light, a beauty control for turning on/off a beauty function, a shutter control for shooting and the like.

The single-lens shooting mode refers to a mode that the electronic equipment only shoots through one camera. The electronic equipment only displays the image shot by one camera in the shooting preview interface in the single-mirror shooting mode. The single-lens shooting may include a front shooting mode, a rear shooting mode, and the like.

Specifically, the front-end shooting mode refers to a mode in which the electronic equipment shoots through a front-end camera. When the electronic equipment is in the front shooting mode, images collected by the front camera in real time can be displayed on a shooting preview interface.

And the rear shooting mode refers to a mode that the electronic equipment shoots through a rear camera. When the electronic equipment is in a rear shooting mode, images acquired by the rear camera in real time can be displayed on a shooting preview interface.

The multi-mirror shooting mode refers to a mode that electronic equipment can shoot through a plurality of cameras. Under the multi-mirror shooting mode, the display screen simultaneously displays images respectively shot by a plurality of cameras in a shooting preview interface, and the images shot by different cameras can be displayed in a splicing mode or in a picture-in-picture mode. The multi-lens shooting mode can include a front-back shooting mode, a back-back shooting mode, a picture-in-picture shooting mode and the like according to the type of the camera used by the electronic equipment and the display mode of images shot by different cameras. In the embodiment of the present application, the multi-mirror shooting may also be referred to as multi-mirror video recording.

The front-back shooting mode refers to a mode in which the electronic equipment can shoot through the front camera and the rear camera simultaneously. When the electronic equipment is in a front-back shooting mode, images (for example, a first image and a second image) shot by the front camera and the back camera can be simultaneously displayed in a shooting preview interface, and the first image and the second image are displayed in a splicing manner. When the electronic equipment is vertically arranged, the first image and the second image can be spliced up and down; when the electronic equipment is transversely arranged, the first image and the second image can be spliced left and right. The display area of the first image is matched with the display area of the second image by default.

In the embodiment of the present application, the types of the camera 293 may be distinguished according to the hardware configuration and the physical location. For example, the plurality of cameras included in the camera 293 may be respectively disposed on the front side and the back side of the electronic device, the camera disposed on the side of the display screen 294 of the electronic device may be referred to as a front camera, and the camera disposed on the side of the rear cover of the electronic device may be referred to as a rear camera; for example, the cameras 293 include cameras having different focal lengths and different viewing angles, and a camera having a shorter focal length and a larger viewing angle may be referred to as a wide-angle camera, and a camera having a longer focal length and a smaller viewing angle may be referred to as a normal camera. The content of the images shot by different cameras is different in that: the front camera is used for shooting the scenery facing the front side of the electronic equipment, and the rear camera is used for shooting the scenery facing the back side of the electronic equipment; the wide-angle camera can shoot a scene with a larger area within a shorter shooting distance range, and the scene shot at the same shooting distance is smaller than the image of the scene shot by using a common lens in the picture. The length of the focal length and the size of the angle of view are relative concepts, and there is no specific parameter limitation, so that the wide-angle camera and the normal camera are also relative concepts, and can be specifically distinguished according to physical parameters such as the focal length and the angle of view.

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

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 1B, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 1B, the application framework layers may include a windows 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 obtain 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 it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, 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, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The telephone manager is used for providing a communication function of the electronic equipment. Such as management of call status (including on, off, etc.).

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

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, 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, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises 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. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

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

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

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

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 following describes an exemplary workflow of software and hardware of the electronic device during shooting in conjunction with capturing a shooting 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 an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of the application framework layer, starts the camera application, further starts the camera drive by calling the kernel layer, and captures a still image or a video through the camera 293. In this embodiment, the touch operation received by the touch sensor may be replaced by an operation of capturing an idle gesture input by the user by the camera 293. Specifically, when the camera 293 captures an operation of an air gesture, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the air gesture operation into an original input event (including an image of the air gesture, a timestamp of the air gesture operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the operation corresponding to the input event. Taking the operation of the space gesture as an example of the operation of switching the shooting mode, the camera application calls the interface of the application framework layer, and then starts other camera drivers by calling the kernel layer, so as to switch to other cameras 293 to capture still images or videos.

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

The electronic equipment can pop up a guide popup window with the air separating gesture when entering the multi-mirror video for the first time, and the using method of the air separating gesture is displayed for a user. The electronic equipment can also pop up a guidance popup window of the air separation gesture when the time difference between the last time of using the air separation gesture by the user and the current time is detected to be larger than first preset time and the user is detected to have a requirement for using the air separation gesture, and the using method of the air separation gesture is displayed for the user. The following description will respectively describe the process of the electronic device popping up the guidance popup window in the above two scenarios with reference to the drawings.

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

As shown in fig. 2A, the handset may display a home interface 301. The home interface 301 may include an icon 302 for a camera application. The mobile phone may receive an operation of the user clicking the icon 302, and in response to the operation, as shown in fig. 2B, the mobile phone 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 of image shooting on an electronic device such as a smart phone and a tablet computer, and may be a system application or a third-party application, and the application does not limit the name of the application. That is, the user may click on the icon 302 of the camera application to open the capture preview interface 303 of the camera application. Without being limited thereto, the user may also invoke the camera application to open the capture preview interface 303 in other applications, such as the user clicking on a capture control in a social-like application to open the capture preview interface 303. The social application can support the user to share the shot pictures or videos and the like with others.

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, a user interface provided when the camera application is in a front shooting mode. It is understood that the default shooting mode may be other modes, such as a rear shooting mode, a front-rear shooting mode, and the like. Still 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 located when the camera application is last exited.

Fig. 2B illustrates an example of the shooting preview interface 303 as a corresponding shooting preview interface when the camera application is in the front shooting mode. As shown in fig. 2B, the capture preview interface 303 can include a preview image 304 capture 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 by the shooting preview interface 303 (i.e., the preview image 304) in real time, so that the user can preview the image currently shot by the camera 293. The shooting mode option 305 is used to provide a plurality of shooting modes for the user to select. The plurality of photographing modes may include: photographed 305a, recorded 305b, multi-mirror recorded 305c, real-time blurring, panoramic, etc. The electronic device may receive an operation of the user to slide the photographing mode option 305 to the left/right, and in response to the operation, the electronic device may turn on the photographing mode selected by the user. It should be noted that, not limited to the illustration in fig. 2B, more or fewer options than those illustrated in fig. 2B may be displayed in the shooting mode option 305.

The shooting mode corresponding to the shot 305a is commonly used single-lens shooting, and may include a front shooting mode, a rear shooting mode, and the like. That is, when the photo 305a is selected, the electronic device can take a photo through the front camera or the rear camera. For a detailed description of the front shooting mode and the rear shooting mode, reference is made to the foregoing description, which is not repeated 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 recorder 305c is selected, the electronic device may perform single-lens shooting through one camera or multi-lens shooting through a plurality of cameras. For the detailed description of the multi-mirror shooting, reference may be made to the foregoing detailed description, and details are 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 start the multiple mirror recording mode, the user may slide the capture mode option 305 to the left and select the multiple mirror recording 305c. When the user's operation of sliding the shooting mode option 305 to the left and selecting the multi-mirror recording 305c is detected, the electronic device may turn on the multi-mirror recording mode and display a shooting preview interface 401 as shown in fig. 3A.

As shown in fig. 3A, after entering the multi-mirror recording mode, the electronic device may display a shooting preview interface 401. The shooting preview interface 401 includes an image 401a (may also be referred to as a second image), an image 401b (may also be referred to as a first image), an air mirror change control 402, a tutorial guidance 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 the rear camera in real time, the image 401b is an image acquired by the front camera in real time, and the image 401a and the image 401b are vertically spliced due to the fact that the electronic equipment is vertically arranged. 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. For example, the first area may be an area where the image 401b in fig. 3A is located, and the second area may be an area where the image 401a in fig. 3A is located.

It should be noted that, in the present application, when the electronic device enters the multi-lens recording mode for the first time, the front camera and the rear camera are turned on by default, and the display mode of the image is determined as the splicing mode by default. However, in other embodiments, the default camera that is turned on may be two rear cameras, one front camera, one rear camera, or the like. In addition, the display mode of the image is not limited to the splicing mode, and may be a picture-in-picture mode, and the like, and is not limited specifically here. Alternatively, the camera application may have a memory function, and after the electronic device enters the multi-mirror recording mode, the electronic device may turn on the camera that was operating when the camera application last exited from the multi-mirror recording mode, and display the camera in the last display mode.

The air-space mirror-changing control 402 can be used for a user to quickly turn on/off the air-space mirror-changing function. After the function of replacing the mirror in the air is started, the user can control the electronic equipment through the air gesture. It should be noted that, after the electronic device enters the multi-mirror video recording mode, the mirror-changing function in the air may be turned on by default. Accordingly, the blank swap control 402 is in an on state (which may also be referred to as a first state) for indicating that the blank swap function is on. Of course, the empty-space mirror-changing function can also be turned off. For example, in response to detecting a touch operation by a user on the air slide control 402, the electronic device may turn off the air slide function. At this time, the air blanking swap control 402 is in an off state (also referred to as a second state) for indicating that the air blanking swap function has been turned off.

The teaching guidance control 403 (also referred to as a first control) can be used to guide the user to learn an overhead gesture of switching the overhead mirror, such as a gesture of turning on a recorded overhead gesture, a gesture of switching between a double mirror and a single mirror, a gesture of turning on/off a picture-in-picture, a gesture of interchanging front and rear lenses, a gesture of ending recording, and the like. It should be noted that the tutorial guidance control 403 is associated with the air-spaced mirror changing function: when the air mirror changing function is turned on (or the air mirror changing control 402 is in an on state), the shooting preview interface 401 may display the teaching guidance control 403; when the air slide mirror function is turned off (or the air slide mirror control 402 is in an off state), the capture preview interface 401 may hide (may be understood as not displaying) the tutorial guide control 403. It should be noted that, after the electronic device starts recording, the teaching guidance control 403 may also be hidden.

The prompt message 404 (also referred to as a guidance prompt) is disposed at a preset position of the teaching guidance control 403 (e.g., disposed at the left side of the teaching guidance control 403 and pointing to the teaching guidance control 403), and is used to remind the user to click the teaching guidance control 403 to view teaching of the space-spaced mirror-changing gesture. For example, the prompt 404 may be a "click viewable" mirror change over space "gesture.

The setting control 405 can be used to adjust parameters for taking a picture (such as resolution, picture scale, etc.), and turn on or off some modes for taking a picture (such as changing mirrors in the air, taking a picture at regular time, capturing a smile, taking a picture under voice control, etc.), etc. Specifically, the electronic device may receive an operation of the user clicking the setting control 405, and in response to the operation, the electronic device may display the setting interface 405a as shown in fig. 3B. The settings interface 405a may include options such as clear mirror change 405b, photo scale, voice-activated photograph, etc. The blanking swap mirror 405b can turn on or off the blanking swap mirror function. Note that the on-off state of the clear mirror 405b in the setting interface 405a and the on-off state of the clear mirror change control 402 in the shooting preview interface 401 are linked, and the on-off state of the clear mirror change 405b and the on-off state of the clear mirror change control 402 are kept identical. That is, if the blank mirror 405b is switched from the on/off state to the off/on state, the blank mirror-changing control 402 is also switched from the on/off state to the off/on state, and vice versa.

The photographing mode switching control 406 may be used to provide a plurality of photographing modes for the user to select, such as a front-back photographing mode, a back-back photographing mode, a picture-in-picture photographing mode, a front photographing mode, a rear photographing mode, and the like.

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

If the user wishes to view the tutorial guidance for the blank gesture, the tutorial guidance control 403 may be clicked. As shown in fig. 4, the electronic device may receive an operation of the user clicking on the tutorial guide control 403, and in response to the operation, the electronic device may display a guide popup 407 (which may also be referred to as a second popup) as shown in fig. 5A. The guide popup 407 may be used to show the use of the blank gesture and related secondary interpretation. Specifically, the guidance pop-up window 407 may include an animation display area 407a (also referred to as a first display area), a text prompt area 407b (also referred to as a second display area), and a confirmation option 407c. The animation display area 407a is used for displaying a plurality of guide videos to show the use method and effect of the space gesture. In one design, the animated display 407a may be presented in an animated manner, which is vivid and understandable, and helps the user to quickly understand and learn the spaced gesture. The content displayed in the text prompt area 407b is matched with the content displayed in the animation display area 407a, and can be used for assisting in explaining the function of the blank gesture being displayed in the animation display area 407a and the use method of the blank gesture.

As shown in fig. 5A to 5C, the animation display area 407a may display a guidance animation that starts recording with a space.

Specifically, as shown in fig. 5A, in the animation display area 407a, the electronic apparatus is in the front-back shooting mode. The electronic device can 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 the clear change mirror icon 410 upon recognition of the "raise hand" gesture. As shown in fig. 5B, when the electronic device continuously detects the gesture of holding the "raise hand", the time progress bar of the blank mirror change icon 410 may be gradually filled, and the shooting preview interface 408 shown in fig. 5C is displayed after a first preset time (e.g., 2 seconds). Compared with 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 recording state is opened by the electronic device.

Correspondingly, the text prompt area 407b may display "start recording in the air, wait for 2 seconds after the mirror-changing icon 410 (specific icon is shown in the figure) appears in the air when the user raises his hand, so as to assist the user in understanding how to start recording using the air gesture.

As shown in fig. 6A-6F, animation display area 407a may also display a guided animation that switches the double mirror and the single mirror in space.

6A-6C show a boot animation of an electronic device switching from a dual mirror to a single mirror.

As shown in fig. 6A, in the animation display area 407a, the electronic apparatus is in the front-back photographing mode. The electronic device can display the rear camera captured image 409a and the front camera captured image 409b on the capture preview interface 408. Here, the image 409a is positioned on the left side of the photographing preview interface 408, and the image 409b is positioned on the right side of the photographing preview interface 408. Still as shown in fig. 6A, the electronic device may display the blank mirror icon 410 upon recognizing the "raise hand" gesture. As shown in fig. 6B, after the electronic device detects the gesture of "palm sliding from right to left", the electronic device may switch from the front-back shooting mode to the front-end shooting mode, and display a shooting preview interface 408 as shown in fig. 6C, where the shooting preview interface 408 includes an image 409B. During the switching process, the image 409a may finally disappear from the capture preview interface 408 according to the gesture of moving from right to left and gradually reducing the display area, while the image 409b finally fills the entire capture preview interface 408 according to the gesture of moving from right to left and gradually increasing the display area.

Fig. 6D-6F show boot animations for an electronic device switching from single to double mirror.

As shown in fig. 6D, the electronic device may display an image 409b captured by the front camera in the capture preview interface 408 when in the front capture mode. In addition, the electronic device may also display the clear mirror icon 410 upon recognizing the "raise hand" gesture. As shown in fig. 6E, upon detecting the gesture of "palm sliding from left to right", the electronic device may switch the photographing mode from the front photographing mode to the front-rear photographing mode and display a photographing preview interface 408 as shown in fig. 6F. In fig. 6F, the electronic apparatus simultaneously displays an image 409a captured by the rear camera and an image 409b captured by the front camera. The image 409a and the image 408b are displayed in a left-right splicing manner, and the image 409a can be finally displayed on the left side of the shooting preview interface 408 according to a gradually increasing display area corresponding to a gesture of sliding the palm from left to right, and the image 408b is finally displayed on the right side of the shooting preview interface 408 according to a corresponding gradually moving from left to right and gradually decreasing display area.

Correspondingly, in fig. 6A to 6F, the text prompt area 407b may display "switch between dual mirrors and single mirror in space, and when the user lifts his hand and turns his hand to the space-separated mirror icon 410, he slides left to push away the left screen and slides right to push away the right screen. (when the screen is erected, the screen is pushed away by sliding the screen on the left, and the screen is pushed away by sliding the screen on the right)', so that the user is assisted in understanding how to switch between the single mirror and the double mirror by using the space gesture.

As shown in fig. 7A-7C, the animation display area 407A may also display a leading animation of turning on/off the picture-in-picture with a space.

As shown in fig. 7A, the electronic device is in the post-capture mode and displays an image 409a captured by the post-camera in the capture preview interface 408. Still as shown in fig. 7A, the electronic device may display the blank mirror icon 410 upon recognizing the "raise hand" gesture. As shown in fig. 7B, the electronic device may, upon recognizing the "raise and punch" gesture, turn on the picture-in-picture mode and display a capture preview interface 408 as shown in fig. 7C. The shooting preview interface 408 shown in fig. 7C simultaneously displays the image 409a and the image 409b. The image 409a is still displayed in the entire display area of the shooting preview interface 408, and the image 409b is superimposed on the image 409a.

In addition, animation display area 407A may also display the inverse of the process of FIGS. 7A-7C. That is, the electronic device may display the capture preview interface 408 as shown in fig. 7B after detecting the "raise hand" gesture in the capture preview interface 408 shown in fig. 7C. Then, when the gesture of "raise hand and make a fist" is detected in the photographing preview interface 408 shown in fig. 7B, the photographing preview interface 408 shown in fig. 7A is displayed. In other words, the user can open or close the picture-in-picture through this "raise and fist" gesture.

Correspondingly, in fig. 7A-7C, the text prompt area 407b may display "open/close picture-in-picture in space, and a fist is made after the open gesture icon 408 appears on the hand-up" to assist the user in understanding how to open/close picture-in-picture in space.

In one possible design, before displaying the capture preview interface 408 shown in fig. 7A, the electronic device may further display a capture preview interface 408 shown in fig. 7D, where the capture preview interface 408 is displayed before the electronic device recognizes a "raise hands" gesture. The shooting preview interface 408 can display a prompt message 411, the prompt message 411 is used for prompting a user, and when the electronic device is in a rear shooting mode, the electronic device can recognize an air gesture by using a front camera, so that the user is prevented from feeling that privacy is invaded. In this embodiment, the prompt information 411 may be an icon. However, in other embodiments, the prompt 411 may be in the form of text or a combination of text and icons. Note that the scene shown in fig. 7D may be displayed in the animation display area 407a as a single guide animation alone, instead of being combined with the animation of switching between the two mirrors and the single mirror in the space.

As shown in fig. 8A to 8C, the animation display area 407a may also display a guide animation of the shot before and after the blank-cut.

As shown in fig. 8A, the electronic device is in the post-capture mode and displays an image 409a captured by the post-camera in the capture preview interface 408. The electronic device may display the clear-to-empty mirror icon 410 upon recognition of the "raise hands" gesture. As shown in fig. 8B, the electronic device may switch the photographing mode from the rear photographing mode to the front photographing mode upon recognizing the gesture of "flip from palm to back of hand" and display a photographing preview interface 408 as shown in fig. 7C. The image 409b captured by the front camera is displayed on the capture preview interface 408.

Correspondingly, in fig. 8A-8C, the text prompt area 407b may display "switch the front and rear shots in the blank space, and turn over from the palm to the back of the hand after the blank hand gesture icon 408 appears on the raising hand" to assist the user in understanding how to switch the front and rear shots using the blank hand gesture.

In this embodiment of the 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 specific contents thereof refer to the foregoing, which is not repeated herein.

As shown in fig. 9A to 9C, the animation display area 407a may also display a guidance animation that ends recording with an empty space.

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 images 409A and 409b are spliced left and right. The electronic device may display the 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 capture preview interface 408 as shown in fig. 9C upon 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 the shooting preview interface after the recording state of the electronic device is finished.

Correspondingly, in fig. 9A-9C, the text prompt area 407b may display "close recording in the space, connect the thumb and the index finger into a circle after the open gesture icon 408 appears on the lift hand, and naturally bend the other fingers" to assist the user in understanding how to close recording using the open gesture.

In the guidance popup 407, the animation display area 407a may automatically play in turn and cyclically play guidance animation that starts recording at an interval, switches the dual mirror and the single mirror at an interval, starts/closes the picture-in-picture at an interval, switches the front and rear shots at an interval, and finishes recording at an interval. It should be noted that the playing sequence of the video recording method is not necessarily played in the order of starting recording in the air, switching between the dual mirror and the single mirror in the air, starting/closing the picture-in-picture in the air, switching between the front and rear lenses in the air, and ending recording in the air, but other playing sequences may exist, which is not limited specifically herein.

It should be noted that the above-mentioned blank gesture is only an example, and the blank gesture may also be other gestures, such as a "victory" gesture, a "left-right waving" gesture, and the like.

In this embodiment, the electronic device may further receive an operation of sliding the guide popup 407 by the user, and in response to the operation, the electronic device may switch the guide animation being played in the animation display area 407a and the prompt information displayed in the text display area 407 b. Illustratively, if the electronic device sequentially plays the corresponding guide animations according to the sequence of starting recording at an interval, switching between a double mirror and a single mirror at an interval, starting/closing picture-in-picture at an interval, switching between front and rear lenses at an interval, and ending recording at an interval. Then the electronic device may display a guidance animation and associated text explanation for the shot before and after the blank switch in the guidance popup 407, as shown in fig. 10. The electronic device may receive an operation of the user sliding the guide popup 407 to the left, 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 the guide animation of the end-of-blank recording.

It should be noted that after the electronic device receives an operation of manually switching animations by a user, the electronic device does not automatically carousel multiple guidance animations. That is, once the animation is manually switched by the user, the electronic device can only switch the guidance animation played by the guidance popup 407 again after receiving the operation of switching the animation by the user again.

The confirmation option 407c is for the user to end the tutorial guidance in advance. For example, the confirmation option 407c may be "know". Illustratively, as shown in fig. 11A, the electronic device may receive an operation of clicking the confirmation option 407c by the user, and in response to the operation, the electronic device closes the guide popup 407 and displays the shooting preview interface 401 shown in fig. 11B. This shooting preview interface 401 is similar to the shooting preview interface 401 shown in fig. 4, except that: the shooting preview interface 401 no longer displays the prompt information 404. It should be noted that, when the user plays any one of the guidance animations, the user may click the confirmation option 407c to close the guidance popup 407.

Therefore, before the electronic equipment does not receive the instruction of switching the animations or the instruction of ending the guidance, the electronic equipment can automatically broadcast a plurality of guidance animations in turn. And after the electronic equipment receives the command of switching the animations, the electronic equipment does not automatically carousel a plurality of guide animations. After the electronic equipment receives the instruction of ending the guidance, the teaching guidance can be ended.

In this embodiment, if the electronic device does not detect that the user has clicked the teaching guidance control 403 and does not use the blank gesture, the electronic device may actively display the guidance pop-up window 407 when entering the multi-mirror recording mode for the second time, and actively guide the user to learn the blank gesture. The description of the guidance pop 407 refers to the related contents 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 the clear gesture. If the electronic device switches the shooting mode in response to the first camera detecting the blank gesture, it may be considered that the user uses the blank gesture. If the electronic device does not switch the shooting mode in response to the first camera detecting the air gesture, it may be considered that the user has not used the air gesture.

That is, the electronic device may prompt the user to view instructional guidance regarding the air-spaced gesture when entering the multi-mirror recording mode for the first time. If the user does not view the tutorial guidance when the electronic device first enters the multi-mirror recording mode (it may be understood that the electronic device does not detect that the user clicked on tutorial guidance control 403), the tutorial guidance for the clear gesture may be automatically played when the electronic device enters the multi-mirror recording mode for the second time. Through many times of guiding the user to watch the teaching guidance about the blank gesture, the probability that the user checks the teaching guidance can be improved, the user can learn the blank gesture as quickly as possible, and the human-computer interaction efficiency is improved.

The guide popup 407 is displayed when the electronic device first enters the multi-mirror recording, and its main purpose is to guide the user to learn how to use the blank gesture. However, after learning, the user may not actually use the space gesture frequently. Thus, the electronic device may also guide the user in the appropriate opportunity to use the clear gesture.

Specifically, when the time difference between the last time when the user uses the blank gesture (which may also be understood as 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 need to use the blank gesture, the electronic device pops up a guidance popup window of the blank gesture, and displays the use method of the blank gesture to the user. The electronic equipment is in a recording state under multi-mirror video recording.

If the time difference between the last time when the user uses the air-separating gesture and the current time is greater than the first preset time, the user can be considered to use the air-separating gesture once, but the user may not use the air-separating gesture again for a long time due to the fact that the user forgets to use the air-separating gesture or forgets to use the air-separating gesture. Under the condition, the user is reminded of using the air-separating gesture, and the influence on the user experience caused by frequently reminding the user of using the air-separating gesture can be avoided. It should be noted that the blank gesture may be any one of a gesture for starting recording in blank space, a gesture for switching between a double mirror and a single mirror in blank space, a gesture for starting/closing a picture-in-picture in blank space, a gesture for switching between front and rear lenses in blank space, and a gesture for ending recording in blank space.

In an optional design, if the electronic device detects that the distance between the user in the front screen and the display screen is greater than or equal to the preset distance within the second preset time after the recording is started, it can be considered that the electronic device detects that the user has a demand for using the space gesture.

Wherein, the user in the front-facing picture can be understood as the user shot by the front-facing camera. The distance between the user and the display screen in the front-facing screen is greater than or equal to the preset distance, which means 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 between the user and the display screen when the user uses the selfie stick-holding electronic device to record, for example, 60 cm.

It can be understood 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 framing of the front camera is easily affected, and thus the quality of the video is affected. Therefore, in this case, it can be considered that the user has a need to use the space gesture, and the user can be guided to use the space gesture.

For example, the electronic device may display a shooting preview interface 401 as shown in fig. 12 when detecting that the distance between the user in the front screen and the display screen is greater than or equal to the preset distance within a second preset time after starting recording the video. This shooting preview interface 401 is similar to the shooting preview interface 401 shown in fig. 11B, except that: the

images

401a and 401b in the shooting preview interface 401 are left-right stitched because the electronic device is laid out horizontally. Further, the shooting preview interface 401 further includes a guide popup 412 (may also be referred to as a first popup). The guide popup 412 is used to present a blank gesture to guide the user in using the blank gesture. For example, the guide popup 412 may display a gesture for blank switching of a double mirror and a single mirror, a gesture for blank switching of front and rear lenses, and a gesture for blank opening/closing of a picture-in-picture.

In an alternative design, if the electronic device detects that the first image is scaled down within a second preset time after the recording is started, where the first image is an area ratio of a face region in the first image, it is determined that there is a demand for using the blank gesture by the user, and the electronic device may display a guidance pop-up window 412 as shown in fig. 12.

In an alternative design, the electronic device may be considered to detect that a user has a need to use a clear gesture while the electronic device is connected to a selfie stick.

Wherein, modes such as electronic equipment accessible earphone hole, bluetooth, WIFI with be connected from rapping bar. For example, after the electronic device starts the bluetooth function, a pairing request sent from a joystick may be received. The pairing request may carry a device name, a media access control (mac) address, and a 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 selfie stick. So, electronic equipment pairs and connects the back with from rapping bar, can confirm self according to this equipment type sign and connect from rapping bar.

When the electronic equipment is connected with the selfie stick, the user can be considered to have the requirement of long-distance shooting, and under the condition, if the user switches the shooting mode through the shooting mode switching control 406 on the touch display screen, the framing of the front camera can be influenced, so that the quality of the video is influenced. Therefore, in this case, it can be considered that the user has a need to use the space gesture, and the user can be guided to use the space gesture.

When the electronic device is connected to the self-timer stick, a shooting preview interface 401 and a guide popup 412 as shown in fig. 12 may be displayed. For a detailed description of the shooting preview interface 401, refer to the foregoing, and are not repeated herein.

It should be noted that the foregoing illustrates that when the electronic device is in the recording state, if the connection of the selfie stick is detected, the electronic device may display a guidance pop-up window 412 as shown in fig. 12. In fact, when the electronic device is connected to the selfie stick, in response to receiving a first operation of the user, the electronic device starts recording a video, and the electronic device displays a guidance popup 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 popup after starting to record the video. In other words, the electronic device may display the guidance popup 412 as long as two conditions that the electronic device is recording a video and is connected to the selfie stick are satisfied when a time difference between a last time (which may also be referred to as a first time) when the user used the blank gesture and a current time is greater than a first preset time.

In an alternative design, the electronic device may be considered to detect that the user has a need to use the clear gesture when the electronic device detects that the user switches the capture mode on the display screen.

Specifically, as shown in fig. 13A, the electronic device may receive an operation of the user clicking a shooting mode switching control 406 (which 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 capture preview interface 401 may include a guide popup 412 and a capture mode selection area 413 (which may also be referred to as a third popup). For the contents of the guidance pop-up window 412, reference is made to the foregoing description, and details are not repeated herein. The photographing mode selection area 413 may show preview interfaces of a plurality of photographing modes, such as a preview interface 413a of a front photographing mode, a preview interface 413b of a rear photographing mode, a preview interface 413c of a picture-in-picture photographing mode, a preview interface 413d of a rear photographing mode, and a preview interface 413e of a front photographing mode and a rear photographing mode.

In short, when the electronic device is in the recording state of the multi-mirror video, if it is detected that the time difference between the last time of using the space gesture by the user and the current time is greater than the first preset time, and it is detected that the distance between the user and the display screen in the front screen is greater than or equal to the preset distance in the second preset time after the recording is started, the electronic device may display the guidance popup window 412 shown in fig. 12. When the electronic device is in a recording state of multi-mirror video, if it is detected that the time difference between the last time of using the space gesture by the user and the current time is greater than the first preset time and is connected to the selfie stick, the electronic device may display a guidance pop-up window 412 as shown in fig. 12. When the electronic device is in the multi-mirror recording state, if it is detected that the time difference between the last time of using the blank gesture by the user and the current time is greater than the first preset time and it is detected that the user switches the shooting mode on the display screen, the electronic device may display a guidance popup 412 shown in fig. 13B.

The above description only exemplifies the guidance and use method of the space gesture when the electronic device is in the front-back shooting mode. In fact, the electronic device may be in any shooting mode under multi-lens video recording, such as a picture-in-picture shooting mode, a front shooting mode, a rear shooting mode, and the like, and is not limited herein.

Therefore, the guiding and using method for the air-separating gesture can remind the user of learning the air-separating gesture when the electronic equipment enters the multi-mirror video for the first time. Particularly, when the time difference between the last time of using the air separating gesture 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 separating gesture, the electronic device pops up the guidance popup window of the air separating gesture, shows the using method of the air separating gesture for the user, increases the possibility of using the air separating gesture by the user, and is beneficial to improving the human-computer interaction efficiency.

The present application further provides a chip system 1400, as shown in fig. 14, which includes at least one processor 1401 and at least one interface circuit 1402.
