In order to bring further shooting creation experience, more and more electronic devices can support simultaneous shooting of a plurality of cameras, so that attractive pictures such as wonderful moments, sensible scenes and the like are recorded.

However, some scenes currently exist, which cannot support simultaneous shooting of a plurality of cameras, and a user needs to be reminded.

Disclosure of Invention

The embodiment of the application provides an abnormality prompting method and electronic equipment, which can prompt a user in time when abnormality exists.

In a first aspect, an embodiment of the present application provides an anomaly prompting method, where the method is applied to an electronic device including a display screen, a first camera, a second camera, and a third camera, where the first camera and the second camera are located on different sides of the display screen, the first camera and the display screen are located on the same side of the electronic device, and the third camera and the second camera are located on the same side of the display screen, and the method includes: the electronic equipment displays a shooting preview interface, the shooting preview interface displays at least one of a first image and a second image, the first image is an image acquired by a first camera in real time, the second image is an image acquired by a second camera in real time, the electronic equipment starts a first function, and the first function is a function of acquiring image data for identifying gestures of a user through the first camera by the electronic equipment; in response to detection of user operation, the electronic device displays a second image, a third image and first prompt information on a shooting preview interface, wherein the third image is an image acquired by a third camera in real time, and the first prompt information is used for indicating that the electronic device cannot enable a first function in a current shooting mode.

It can be appreciated that the electronic device may switch from any one of a front shooting mode, a rear shooting mode, a front-rear shooting mode, and a picture-in-picture shooting mode to a rear shooting mode, and after switching to the rear shooting mode, the electronic device may remind a user that the space-apart mirror-changing function cannot be used in the rear shooting mode.

In a possible implementation manner, the shooting preview interface further includes a second control, and in response to detecting the user operation, the electronic device continues to display the second image on the shooting preview interface, and displays a third image and a first prompt message acquired in real time from a third camera, including: responding to the operation of a user on the second control, displaying a first popup window on a shooting preview interface by the electronic equipment, wherein the first popup window comprises an identifier of a first shooting mode, and the first shooting mode is a mode that the electronic equipment shoots through a second camera and a third camera at the same time; and responding to the operation of the user on the identification of the first shooting mode, the electronic equipment displays a second image on a shooting preview interface and displays a third image and first prompt information. That is, the user may switch from the other shooting mode to the post-shooting mode through a control (e.g., a second control) on the interface.

In one possible implementation, in response to detecting the user operation, the electronic device continues to display the second image on the shooting preview interface, and displays a third image and the first prompt information acquired in real time from the third camera, including: in response to the first camera detecting the first gesture, the electronic device displays a first identifier on the shooting preview interface; and in the preset time after the first mark is displayed, responding to the fact that the first camera detects the second gesture, and continuously displaying the second image on the shooting preview interface by the electronic equipment to display the third image and the first prompt information. That is, the user may switch from the other shooting mode to the post-shooting mode through a blank gesture (e.g., a second gesture).

In one possible implementation, before detecting the user operation, the method further includes: detecting the temperature of equipment in real time; if the temperature of the equipment is not in the preset temperature range, the electronic equipment displays second prompt information on the shooting preview interface, and the second prompt information indicates that the electronic equipment has closed the first function.

It can be seen that, according to the guiding usage method of the blank gesture provided by the embodiment of the application, when the electronic device is in any one shooting mode (including a front shooting mode, a rear shooting mode, a front-back shooting mode and a picture-in-picture shooting mode), the device temperature is detected in real time, and when the device temperature is detected not to be within the preset temperature range, the blank mirror changing function (namely the first function) is closed and the second prompt information is displayed. Therefore, when the temperature of the equipment is abnormal, the user can be timely reminded that the electronic equipment is closed for changing the mirror at intervals, and the man-machine interaction efficiency is improved.

It can be appreciated that if the electronic device does not begin recording video, the shooting preview interface may include a first control that may be used to turn on or off the alternate mirror function. When the electronic equipment detects that the equipment temperature is not in the preset range, the function of switching off the empty mirror can be automatically closed, and the state of the first control can be switched on the shooting preview interface, and the first state is switched into the second state so as to indicate that the electronic equipment has closed the function of switching off the empty mirror.

In one possible implementation, in a case where the electronic device is recording video, the method further includes: if the temperature of the equipment is not in the preset temperature range, the electronic equipment stops recording the video in response to detection of the user operation, and a first control is displayed on a shooting preview interface, wherein the first control is in a second state, and the second state indicates that the electronic equipment has closed a first function.

That is, if the device temperature is not within the preset temperature range, the electronic device may automatically close the space-saving mirror-changing function. During this time, if the electronic device receives the operation of stopping recording the video by the user, the electronic device may stop recording the video, and display the first control on the shooting preview interface after stopping recording the video, where the first control is in the second state.

In one possible implementation, the first control is in an non-clickable state during a period when the device temperature is not within a preset temperature range. That is, the user cannot turn on the air-blocking mirror-changing function through the first control during the period when the device temperature is not within the preset temperature range.

In one possible implementation, the method further includes: if the temperature of the equipment is not in the preset temperature range, responding to the detection of the operation of the user on the first control, and displaying third prompt information on a shooting preview interface by the electronic equipment, wherein the third prompt information indicates that the first function of the electronic equipment cannot be started due to abnormal temperature. That is, in the case where the device temperature is not within the preset temperature range, the user cannot turn on the air-separation mirror-changing function.

In one possible implementation, if the device temperature is greater than or equal to a first preset temperature, or the device temperature is less than or equal to a second preset temperature, the device temperature is not within a preset temperature range, wherein the first preset temperature is greater than the second preset temperature.

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.

The display 294 is used to display images, videos, and the like. In some embodiments, the electronic device may include 1 or N displays 294, N being a positive integer greater than 1. In an embodiment of the present application, the display 294 may be used to display images taken by any one or more cameras 293, for example, to display multiple frames of images taken by one camera in a capture preview interface, or to display multiple frames of images from one camera 293 in a saved video file, or to display a photograph from one camera 293 in a saved picture file.

The SIM card interface 295 is for interfacing with a SIM card. The SIM card may be inserted into the SIM card interface 295 or removed from the SIM card interface 295 to enable contact and separation from the electronic device 200. The electronic device 200 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 295 may support Nano SIM cards, micro SIM cards, and the like.

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

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 rows (Android runtime) 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 the application 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 runtime 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, a method provided by the present application will be described with reference to the drawings.

As shown in fig. 2, the handset may display a main interface 301. The main interface 301 may include an icon 302 of a camera application. The mobile phone may receive an operation of clicking on the icon 302 by the user, and in response to the operation, as shown in fig. 3, the mobile phone may open the camera application and display a photographing 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. 3 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. 3, the shot preview interface 303 may include a preview image 304, a 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. 3, more or fewer options than those shown in fig. 3 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. 3, 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 the photographing preview interface 303 as shown in fig. 4A.

As shown in fig. 4A, after entering the multi-mirror video recording mode, the electronic device displays a shooting preview interface 303. The shooting preview interface 303 includes an image 306a, an image 306b, a blank mirror control 307, a setup control 308, a shooting mode switch control 309, a teaching guide control 310, and the like. The image 306a is an image photographed by a rear camera, the image 306b is an image photographed by a front camera, and the image 306a and the image 306b are spliced up and down due to the vertical arrangement of the electronic device.

In the application, the front camera and the rear camera can be started by default when the electronic equipment is in the first multi-mirror video recording mode, 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 can have a memory function, after the electronic equipment enters the multi-mirror video mode, the electronic equipment can start a camera which 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 space-apart mirror-changing control 307 can be used for a user to quickly start/stop the space-apart mirror-changing function. After the function of changing the mirror at intervals is started, a user can control the electronic equipment through a specific interval gesture. 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 307 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 307, the electronic device may turn off the blank mirror function. At this time, the blank mirror control 307 is in an off state (may also be referred to as a second state) for indicating that the blank mirror function has been turned off.

The setup controls 308 may be used to adjust parameters of the photograph taken (e.g., resolution, picture scale, etc.), to turn on or off some of the ways used for taking the photograph (e.g., alternate mirror, timed photograph, smile snapshot, voice-activated photograph, etc.), etc. Specifically, the electronic device can receive a user click on the setting control 308, and in response to the operation, the electronic device can display a setting interface 308a as shown in fig. 4B. The setup interface 308a may include options for a space-apart mirror 308b, a photo scale, voice-controlled photographing, and the like. The alternate mirror 308b may turn on or off the alternate mirror function. Note that, the on-off state of the blank mirror 308b in the setting interface 308a is linked with the on-off state of the blank mirror control 307 in the shooting preview interface 303, and the on-off state of the blank mirror 308b is consistent with the on-off state of the blank mirror control 307. That is, if the blank mirror 308b is switched from the on state/off state to the off state/on state, the blank mirror control 307 is also switched from the on state/off state to the off state/on state, and vice versa.

In addition, the space-saving and changing mirror 308b can prompt a user, and the electronic device can recognize the space-saving gesture by utilizing the front camera during multi-mirror video recording. For example, the alternate mirror 308b may include text information of "switch multi-mirror mode by front camera recognition gesture during multi-mirror video recording". That is, the electronic device may inform the user that the electronic device may recognize the blank gesture using the front camera when the user opens the blank mirror change function by setting the control 308, avoiding the user from feeling that the privacy is violated.

The shooting mode switch control 309 can be used to provide a variety of shooting modes for selection by the 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.

In the embodiment of the application, the electronic equipment can have a function of changing the mirror at intervals. The function of spacing and changing the mirror can be as follows: under the multi-mirror video recording, the electronic equipment can recognize the air-separation gesture through the front-mounted camera so as to switch the shooting mode. The function of changing the mirror with a space of the electronic device will be described with reference to the accompanying drawings.

As shown in fig. 5A, 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), a shooting mode switching control 402, and the like. The image 401a is an image acquired by the rear camera in real time, and the image 401b is an image acquired by the front camera in real time. In addition, the image 401a and the image 401b are stitched from side to side because the electronic device is laid horizontally. 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 region may be the region of the image 401b in fig. 5A, and the second region may be the region of the image 401a in fig. 5A.

As shown in fig. 5A, if the user wishes to switch the shooting mode of the electronic device, a blank gesture, for example, a blank gesture of "lift" may be input to the electronic device (it may be understood that the user keeps facing the display screen and keeps holding "lift" and may also be referred to as a first gesture). The front camera of the electronic device may capture a blank gesture (i.e., image 401 b) entered by the user and display it in the capture preview interface 401. In addition, the electronic device may further analyze the captured image 401B, and when the "lift hand" blank gesture is recognized, display the capture preview interface 401 as shown in fig. 5B. The shooting preview interface 401 shown in fig. 5B is similar to the shooting preview interface 401 shown in fig. 5A, except that: the shot preview interface 401 shown in fig. 5B includes prompt information 403 for prompting the user that the electronic device has entered a "ready" state (which may be understood as a state in which the user's hold gesture is ready to be further recognized), and the user may enter the hold gesture as desired. For example, as shown in fig. 5B, the prompt 403 may be an icon of a blank gesture. In one possible design, the prompt 403 may further include text information prompting the user for a gesture operation to be completed within a first predetermined time, such as "gesture operation is required to be completed within 3 seconds".

Meanwhile, the hint information 403 may also include a timeline that may be used to indicate when the electronic device entered the "ready" state. Wherein the electronic device starts timing from a time (e.g., a first time) when the electronic device enters a "ready" state, at which time the timeline is blank; the electronic device stops timing after a first preset time at a first moment, and the time progress bar is filled up at the moment. After the electronic device enters the "ready" state, the user needs to input a space-apart gesture before the timeline is filled (which can be understood as being within a first preset time) to achieve control over the electronic device.

For example, the electronic device may switch from the front-rear shooting mode to the front-shooting mode or the rear-shooting mode when a blank gesture input by a user is detected. The interface involved in switching the electronic apparatus from the front-rear photographing mode to the front-photographing mode will be described below based on the photographing scene shown in fig. 5A to 5B.

As shown in fig. 5C, if the user desires the electronic device to switch from the front-back shooting mode to the front shooting mode, when the electronic device displays the shooting preview interface 401 shown in fig. 5B, a blank gesture (a gesture that can be understood simply as a left-hand gesture of the palm, and also referred to as a third gesture) of "moving the palm from right to left" may be input to the display screen. In response to detecting a blank gesture of "palm moving from right to left" input by the user, the electronic device may switch the photographing mode from the front-rear photographing mode to the front photographing mode, and display a photographing preview interface 401 as shown in fig. 5D. As shown in fig. 5D, after the electronic device switches to the front-end shooting mode, an image 401b shot by the front-end camera may be displayed in the shooting preview interface 401. It should be noted that, when there are a plurality of front cameras, the front camera working at this time may be the default front main camera of the electronic device.

It should be noted that, the electronic device may also switch the shooting mode from the front-back shooting mode to the other shooting mode in response to detecting other blank gestures of the user. For example, in the shooting scene shown in fig. 5B, in response to detecting a blank gesture of "stretch palm and then make a fist" input by the user, the electronic device may switch the shooting mode from the front-back shooting mode to the picture-in-picture shooting mode. Or in response to detecting a "reverse palm" blank gesture entered by the user, the electronic device may swap the positions of image 401a and image 401b, i.e., change the position of image 401a from the original left of the screen to the right of the screen, and change the position of image 401b from the original right of the screen to the left of the screen. Or in response to detecting a "winning" blank gesture entered by the user, the electronic device may switch the shooting mode from a front-to-back shooting mode to a back-to-back shooting mode. Specifically, the electronic device may switch the image 401b to the image 401c (may also be referred to as a third image), where the image 401c is an image acquired by another rear camera (may be referred to as a third camera) in real time.

When the space-apart mirror-changing function is started, the electronic device needs to recognize a space-apart gesture of the user through at least one front-facing camera, and further execute an operation corresponding to the space-apart gesture. That is, when the electronic device recognizes the blank gesture, the blank mirror function cannot be enabled.

In the embodiment of the application, the electronic equipment can simultaneously utilize two cameras to shoot images. When the electronic equipment is in a rear shooting mode, the two rear cameras are in a working state, so that the electronic equipment cannot recognize a space gesture of a user through the front cameras. Therefore, when the electronic device is in the rear shooting mode, the space-apart mirror-changing function cannot be started.

The electronic device can remind a user that the function of changing the mirror by spacing cannot be used when the shooting mode is switched to the post shooting mode. As shown in fig. 6A, the electronic device may display a shooting preview interface 401. The shooting preview interface 401 is similar to the shooting preview interface 401 shown in fig. 5A, and will not be described again.

As shown in fig. 6A, the electronic device may also receive an operation in which the user clicks the photographing mode switching control 402 (may also be referred to as a second control), and in response to the operation, the electronic device may display the photographing preview interface 401 shown in fig. 6B on the photographing preview interface 401. The shooting preview interface 401 may include a shooting mode selection area 404 (which may also be referred to as a first popup). The shooting mode selection area 404 may display preview interfaces of multiple shooting modes, such as a preview interface 404a of a front shooting mode, a preview interface 404b of a rear shooting mode (may also be referred to as a first shooting mode), a preview interface 404c of a picture-in-picture shooting mode, a preview interface 404d of a rear shooting mode, and a preview interface 404e of a front and rear shooting mode.

As shown in fig. 6B, the electronic apparatus may receive an operation in which the user clicks the preview interface 404B of the rear photographing mode, switch the photographing mode from the front-rear photographing mode to the rear-rear photographing mode in response to the operation, and display the photographing preview interface 401 as shown in fig. 6C.

As shown in fig. 6C, the image displayed in the photographing preview interface 401 is switched from the images 401a and 401b shown in fig. 6A to an image 401a and an image 401C (may also be referred to as a third image). The image 401a is an image captured by a common camera in the rear camera, and the image 401c is an image acquired by a wide-angle camera in the rear camera in real time. It can be seen that image 401c has a larger viewing range than image 401 a. In addition, the shooting preview interface 401 further includes an abnormality notification 405 (may also be referred to as a first notification). The abnormality notification 405 is used to alert the user that the space-saving lens changing function cannot be used in the rear-rear shooting mode, for example, "space-saving lens changing cannot be used at rear/rear".

Or the user may also use the space-saving gesture to switch from the other shooting mode to the post-shooting mode. The specific switching process is described in the foregoing description about the space-apart mirror-changing functional portion, and is not repeated herein.

In the above description, the electronic device is merely described by taking an example of switching from the front-rear shooting mode to the rear-rear shooting mode, and in fact, the abnormality indication information 405 (may also be referred to as the first abnormality indication information) may be displayed when the electronic device is switched from any of the other shooting modes (for example, the picture-in-picture shooting mode, the front shooting mode, and the rear shooting mode) to the rear-rear shooting mode. The mode of switching the electronic device from any other shooting mode to the back shooting mode is the same as the mode of switching the electronic device from the front shooting mode to the back shooting mode, and is not described herein.

The electronic device may display the abnormality notification 405 when it first switches to the post-shooting mode after entering the multi-mirror video recording. The method can avoid frequent reminding of the user by the electronic equipment and reduce redundant information.

It should be noted that the above description only takes the abnormality reminding process of the electronic device in the recording process as an example. When the electronic device is in an unrecorded state, the electronic device can also be switched from any shooting mode to a post shooting mode, and abnormal prompt information 405 is displayed.

If the electronic equipment has started the space-apart mirror-changing function, the electronic equipment can also close the space-apart mirror-changing function and remind a user when the equipment temperature is too high or too low. The following description will take an example in which the electronic apparatus is in the front-rear shooting mode.

Referring to fig. 7A, a capture preview interface 401 is shown when the electronic device is at a normal temperature. The shooting preview interface 401 shown in fig. 7A is similar to the shooting preview interface 401 shown in fig. 6A, except that: the shooting preview interface 401 shown in fig. 6A is in a recorded state, and the shooting preview interface 401 shown in fig. 7A is in an unrecorded state, but this does not affect the abnormality alert.

Referring to fig. 7B, a capture preview interface 401 is shown when the electronic device is too hot. In comparison with the photographing preview interface 401 shown in fig. 7A, abnormality notification 407 (which may also be referred to as second notification) is displayed in the photographing preview interface 401 shown in fig. 7B. The abnormality notification 407 is used to notify the user that the electronic device has turned off the function of changing the mirror at a distance due to an excessive device temperature, for example, "the device temperature is too high" the mirror is changed at a distance "off". In addition, the state in which the blank mirror control 406 (which may also be referred to as a first control) is in changes from the on state shown in fig. 7A to the off state shown in fig. 7B (which may also be referred to as a second state).

Specifically, the temperature sensor of the electronic device may detect the device temperature of the electronic device in real time and transmit it to the processor 210. The processor 210 may consider that the device temperature of the electronic device is too high when the device temperature is greater than a preset first temperature (may also be referred to as a first preset temperature), and control the display 294 to display the abnormality notification 407 on the shooting preview interface 401.

Referring to fig. 7C, a capture preview interface 401 is shown when the electronic device temperature is too low. In comparison with the photographing preview interface 401 shown in fig. 7A, abnormality notification 408 (which may also be referred to as second notification) is displayed in the photographing preview interface 401 shown in fig. 7C. The anomaly prompt 408 is used to prompt the user that the electronic device has turned off the alternate mirror function due to too low a device temperature, e.g., "too low a device temperature" alternate mirror "off. In addition, the state in which the blank mirror control 406 is in changes from the on state shown in fig. 7A to the off state (which may also be referred to as a second state) shown in fig. 7C.

Specifically, the temperature sensor of the electronic device may detect the device temperature of the electronic device in real time and transmit it to the processor 210. The processor 210 may consider that the device temperature of the electronic device is too low when the device temperature is less than a preset second temperature (may also be referred to as a second preset temperature), and control the display 294 to display the abnormality notification 408 on the photographing preview interface 401.

It can be appreciated that when the temperature of the device of the electronic device is too high, the user continues to use the space-saving mirror-changing function, which may aggravate the heating condition of the electronic device, so that the space-saving mirror-changing function needs to be turned off. When the equipment temperature of the electronic equipment is too low, the internal resistance of the battery of the electronic equipment is increased, and at the moment, if a user continues to use the function of changing the mirror by spacing, the current of the battery can be increased instantaneously, so that the voltage of the battery is pulled down instantaneously, and the electronic equipment is powered off, so that the function of changing the mirror by spacing is required to be closed.

The electronic device may also not display (or hide) the anomaly prompt 407 or the anomaly prompt 408 after a predetermined time. For example, the electronic device may display the photographing preview interface 401 shown in fig. 7D after a preset time. Compared to the photographing preview interface 401 shown in fig. 7A, the state in which the blank mirror change control 406 is in is changed from the on state shown in fig. 7A to the off state shown in fig. 7D.

As shown in fig. 7D, if the user wishes to turn on the alternate mirror function, the alternate mirror control 406 may be clicked. The electronic device may receive an operation of clicking the space-apart mirror control 406 by a user, and in response to the operation, the electronic device may determine a temperature interval in which a device temperature is located, and perform a corresponding operation.

Specifically, if the electronic device determines that the device temperature is greater than the preset first temperature (i.e., the device temperature is too high), an abnormal prompt message 410 (may be referred to as a third prompt message) as shown in fig. 7E may be displayed, and the abnormal prompt message 410 is used to remind the user that the device temperature is too high to open the function of changing the lens while keeping the lens apart. If the electronic device determines that the device temperature is less than the preset second temperature (i.e., the device temperature is too low), a shooting preview interface 401 as shown in fig. 7F may be displayed, and the user may be reminded of the too low device temperature to turn on the function of changing the lens by using the abnormal prompt information 411 (which may be referred to as a third prompt information). If the electronic device determines that the device temperature is between the preset first temperature and the preset second temperature, the air-separation mirror-changing function may be turned on and a prompt message 412 shown in fig. 7G may be displayed to indicate that the air-separation mirror-changing function is turned on.

In an alternative embodiment, the blank mirror change control 406 may be grayed out (not shown) when the device temperature is greater than a preset first temperature or less than a preset second temperature. In other words, the blank mirror control 406 cannot be clicked during the period when the device temperature is greater than the preset first temperature or less than the preset second temperature until the device temperature returns to normal (less than the preset first temperature and greater than the preset second temperature), the blank mirror control 406 can change to the second state for the user to turn on the blank mirror function.

If the user wishes to turn on the alternate mirror function, the setup control 308 may also be clicked. The electronic device may receive an operation of clicking the space changing mirror 308b by the user, and in response to the operation, the electronic device may determine a temperature interval in which the device temperature is located, and perform a corresponding operation.

In summary, the abnormality prompting method provided by the application can prompt the user that the function of changing the mirror with a space can not be used in time when the electronic equipment is in the post-shooting mode or the equipment temperature is abnormal (the equipment temperature is higher than the preset first temperature or lower than the preset second temperature), thereby being beneficial to prompting the user to control the electronic equipment in an available mode and improving the man-machine interaction efficiency.
