Background

The outward folding screen is a display screen which can be folded outwards, and the electronic equipment with the outward folding screen comprises an outward folding screen mobile phone, an outward folding screen tablet personal computer and the like. Taking an out-folded folding screen mobile phone as an example, as shown in fig. 1A, the out-folded folding screen mobile phone may include an unfolded state and a folded state, when the out-folded folding screen mobile phone is in the unfolded state, the whole screen faces to the user, that is, the main screen and the back screen face to the same, and the display area seen by the user is the whole screen; when the mobile phone with the folding screen is in a folding state, the main screen and the back screen face opposite directions, and the main screen and the back screen are different display areas of the same screen.

A camera may be provided on an electronic device with an out-folded folding screen, which may support a post self-timer. Taking the out-folded folding screen mobile phone as an example, as shown in fig. 1B, the main screen may be equipped with a front camera and a rear camera, where the front camera is located in the display area of the main screen, and the rear camera is located in the back area of the main screen (opposite to the main screen).

The main screen and the back screen can display camera interfaces, and the camera interfaces displayed by the main screen and the back screen can adopt different camera modes. The camera mode herein refers to a shooting mode of a camera, shooting magnification, and the like. The shooting mode can be a portrait mode, a night view mode, a large aperture mode, a shooting mode, a video mode, a professional mode and the like, and the shooting magnification can be 0.7 times, 1 times, 1.3 times, 2 times and the like. As shown in fig. 1C, the back screen may display a camera interface of a first camera mode, where the first camera mode includes 4 shooting modes, that is, a portrait mode, a night view mode, a shooting mode, and a video mode, and the supportable shooting magnification is 0.7 times, 1 times, and 1.3 times; the main screen and the whole display screen can display a camera interface of a second camera mode, wherein the second camera mode comprises 6 shooting modes, namely a portrait mode, a night scene mode, a large aperture mode, a shooting mode, a video mode and a professional mode, and the shooting magnification capable of being supported is 1 time and 2 times. In addition, as shown in fig. 1D, when the folded-out folding-screen mobile phone is in a folded state, the user can orient the back screen to himself and shoot by using the rear camera, and meanwhile, the back screen can display a shooting picture acquired by the rear camera, so that the mode is called a rear self-timer state; meanwhile, a button for switching to the main screen can be displayed on the back screen, and a user can switch the camera interface to the main screen for display by clicking the button.

However, when the camera is in the post-auto-shooting state, the camera enters a power saving mode (the power saving mode refers to that the camera enters a sleep state in order to save power consumption, and the camera interface is closed at this time, and the user can wake up the camera only when clicking the screen), if the user performs the operation of switching the screen in the power saving mode, the situation that the camera mode is disordered when the user wakes up the camera occurs, so that the current camera does not support the power saving mode when in the post-auto-shooting state.

In order to facilitate understanding of the solutions provided by the embodiments of the present application, the following description describes related concepts related to the embodiments of the present application:

1. outward folding screen

The outward folding screen is a display screen which can be folded outwards, and the electronic equipment with the outward folding screen comprises an outward folding screen mobile phone, an outward folding screen tablet personal computer and the like. Taking an out-folded folding screen phone as an example, as shown in fig. 1A, the out-folded folding screen phone may include an unfolded state and a folded state. When the folding screen mobile phone is in an unfolding state, the whole screen faces to a user, namely the main screen and the back screen face to the same direction, and the display area which can be seen by the user is the whole screen, so that a better visual effect can be obtained. When the mobile phone with the folding screen is in a folding state, the main screen and the back screen face opposite directions, and on the folding screen, the main screen and the back screen are different display areas of the same screen. The screen orientation refers to a direction in which the front surface of the display screen faces.

2. Camera mode

The camera mode refers to a shooting mode, shooting magnification, and the like of the camera. The shooting mode may be a portrait mode, a night view mode, a large aperture mode, a shooting mode, a video mode, a professional mode, a panoramic mode, etc., and of course, more shooting modes may be included, which is not limited herein; the photographing magnification may be 0.7 times, 1 times, 1.3 times, 2 times, etc., and of course, more photographing magnifications may be included, which is not limited thereto. Different camera interfaces may employ different camera modes. Taking an out-folded folding screen mobile phone as an example, the main screen and the back screen can both display camera interfaces, and the camera interfaces displayed by the main screen and the back screen can adopt different camera modes. Illustratively, as shown in fig. 1C (a), the back screen displays a camera interface of a first camera mode (i.e., a first camera interface), which includes 4 photographing modes, i.e., a portrait mode, a night view mode, a photographing mode, a video recording mode, and can support photographing magnifications of 0.7 times, 1 times, 1.3 times; as shown in (b) of fig. 1C, the main screen displays a camera interface of a second camera mode (i.e., a second camera interface) including 6 photographing modes, i.e., a portrait mode, a night view mode, a large aperture mode, a photographing mode, a video mode, a professional mode, and photographing magnification that can be supported is 1-fold, 2-fold. As shown in (C) of fig. 1C, the entire display screen displays a camera interface of a second camera mode (i.e., a second camera interface), which also includes 6 photographing modes, i.e., a portrait mode, a night view mode, a large aperture mode, a photographing mode, a video mode, a professional mode, and can support photographing magnifications of 1-2 times.

It should be noted that, the second camera interface has more camera modes than the first camera interface, the supported magnification is larger, the interface displaying the camera picture is larger, and the user can execute more functional operations on the second camera interface; compared with the second camera interface, the first camera interface adopts fewer camera modes, the supported magnification is smaller, the operation is easier and more simplified, and the focusing self-timer is realized.

3. Power saving mode of camera

The power saving mode of the camera means that the camera can enter a sleep state in order to reduce power consumption and save electric quantity; when the camera enters a sleep state, closing a camera interface, and closing physical camera equipment (namely physical cameras such as a rear camera); and when the user clicks the screen, the user can wake up the camera, so that the camera is in a sleep state, a camera interface is displayed, and the physical camera equipment is started. The sleep state is a state designed to reduce the consumption of the battery. When the camera enters a sleep state, the camera does not run any background process, and at the moment, the camera is in an idle state, so that the power consumption can be reduced.

4. Rear-mounted self-timer

An application program of a camera can be installed on the electronic equipment with the folding screen, and the camera can support the post self-timer. Taking an out-folded folding screen mobile phone as an example, as shown in fig. 1B, a main screen may be equipped with a front camera and a rear camera, where the front camera is located in a display area of the main screen, and the rear camera is located in a back area of the main screen (opposite to the main screen and same to the back screen); the main screen and the back screen can display camera interfaces, and the camera interfaces displayed by the main screen and the back screen can adopt different camera modes.

In addition, as shown in fig. 1D, when the folding-out folding-screen mobile phone is in a folded state, the user can orient the back screen to himself and shoot by using the rear camera, and meanwhile, the back screen can display a shooting picture acquired by the rear camera, so that the mode is called a rear self-timer state. When a user opens the camera, shooting by adopting a rear camera by default, and if a camera interface is displayed on a back screen at the moment, considering that the camera directly enters a rear self-shooting state; if the camera interface is displayed on the main screen at this time, a button for switching to the back screen is also displayed on the main screen, and the user can click on the button for switching to the back screen, so that the camera interface is displayed on the back screen, and at this time, the camera is considered to enter a rear-mounted self-timer state. Of course, a button for switching to the main screen can be displayed on the back screen, and the user can switch the camera interface to the main screen for display by clicking the button; the user can also expand the mobile phone, so that the camera interface is switched to the whole display screen for display.

However, when the camera is in the rear-mounted self-timer state, the camera enters a power saving mode, if the user performs the operation of switching the screen in the power saving mode, a situation that the camera mode is disordered occurs when the camera is awakened, for example, the main screen should be a camera interface (i.e. a second camera interface) displaying a second camera mode, but a camera interface (i.e. a first camera interface) displaying a first camera mode is displayed when the camera is awakened; so the current camera cannot support the power saving mode when in the rear self-timer state.

In order to realize a rear-mounted self-timer function when a camera is in a power saving mode and avoid the condition that the camera mode is disordered when the camera is awakened, the application provides a switching method of the camera mode and electronic equipment. In a specific implementation, the above mentioned method of switching camera modes may be performed by the electronic device 100. The electronic device 100 may be an electronic device with an out-folded folding screen, such as an out-folded folding screen mobile phone, an out-folded folding screen tablet computer, an out-folded folding screen notebook computer, or the like, but is not limited thereto.

In addition, an operating system is run on the components. Such as iOS, android, etc. The operating system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In this embodiment, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated. It should be noted that, although the embodiment of the present application is described by taking an Android system as an example, the basic principle is also applicable to electronic devices of other operating systems.

Fig. 3 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application. The software structure adopts a layered architecture, the layered architecture divides the software into a plurality of layers, and each layer has clear roles and division work. The layers communicate with each other through a software interface. In this embodiment of the present application, an operating system (for example, an Android system runs on an AP) may be divided into three layers, namely, an application layer (APP), an application framework layer (FWK), and a hardware abstraction layer (hardware abstraction layer, HAL) from top to bottom.

The application layer may include a series of application packages, among other things. As shown in fig. 3, the application package may include an application such as a camera. In the present embodiment, a camera refers to a camera application. Camera applications may include camera Interface modules (which may be referred to as camera api2 modules), post self-timer management (which may be referred to as reacamselfiedmanager), power saving services (which may be referred to as blackscreen service), user Interface (UI) modules, and the like.

The camera api2Module is a Module in the camera application, and is used for managing and controlling the camera application, and providing an interface of the camera application.

The rearcamselfiedmanager is a module in the camera application and is used for managing the rear self-timer state of the camera, wherein the rear self-timer state is a state that a shooting picture acquired by a rear camera is displayed on a back screen. In the embodiment of the application, the rearcamselfiedmanager can be responsible for entering and exiting the post self-timer state, and can register monitoring of a power saving mode with blackscreen service and the like. In embodiments of the present application, post self-timer management (rearcamselfiedmanager) may be initiated in response to an operation in which the camera is started.

The BlackScreen service is a module in the camera application, and is used for enabling the camera to enter a sleep state when the camera is in a power saving mode, closing a camera interface at the moment, and closing physical camera equipment through a FWK layer and a HAL layer; when the camera is woken up, the camera exits the sleep state and the physical camera device may be turned on through the FWK layer, HAL layer. In this embodiment of the present application, when the blackscreen service monitors that the camera exits from the sleep state under the condition that the reasemselfiedmanager registers the monitoring in the power saving mode with the blackscreen service, a callback function may be invoked to notify that the reasemselfiedmanager is currently awakened.

The UI module is a module in the camera application, and is used for displaying an interface of the electronic device, such as a first camera interface, a second camera interface, and the like.

The application framework layer provides application programming interface (application programming interface, API) frameworks for application developers to access core functions and various services and management tools, including interface management, data access, messaging at the application layer, management of application packages, telephony management, location management, etc. The application framework layer includes a number of predefined functions. As shown in fig. 3, the application framework layer may include a camera service (camera service) or the like. The camera service is used for being responsible for starting flow scheduling of camera applications, creation and management of processes, creation and management of windows and the like.

The hardware abstraction layer is an interface layer between the operating system kernel and the hardware circuitry, which aims at abstracting the hardware. It hides the hardware interface details of the specific platform and can provide a virtual hardware platform for the operating system. As shown in fig. 3, the hardware abstraction layer may include a camera device interface (camera device), a camera device session interface (camera device session), a camera provisioning service (camera provider), and the like. Wherein the camera device is an abstract representation of a single camera connected to the device, the camera device may support fine-grained control and post-processing of captured images at high frame rates; the camera device session is used for creating a camera device session, storing attributes, configuration information and the like required by the camera device session; the camel provider is used to enumerate individual devices and manage their status, and can turn on and off physical camera devices (e.g., a rear camera).

Based on the software structure, the embodiment of the application provides a flow diagram of a method for switching camera modes based on the software structure. As shown in fig. 4, the method for switching the camera mode includes the following steps S401 to S406. Wherein:

s401, the electronic equipment responds to the operation of starting the camera by a user, and calls a camera interface module to start the camera; when the camera is started, the post self-timer management is initialized.

In the embodiment of the application, a user can start a camera (also called as a camera application) to shoot; the electronic device invokes the camera interface module to turn on the camera in response to a user turning on the camera. The post self-timer management needs to be initialized while the camera is turned on. At the moment, the electronic equipment is in a folded state, a first camera interface is displayed on the back screen through the user interface module, and the camera is in a rear-mounted self-timer state. The first camera interface is a camera interface in a first camera mode (as shown in fig. 1C (a)), and the rear self-timer state refers to a state in which a shooting picture acquired by a rear camera is displayed on a back screen (as shown in fig. 1D).

S402, the post self-timer management registers monitoring to the power saving service.

In the embodiment of the application, the post self-timer management can register monitoring with the power saving service in a static configuration mode. By snoop is meant a mechanism for listening to the occurrence of an event and performing the corresponding action when the event occurs. The event of the specific monitoring of the post self-timer management is that the camera is awakened when the camera is in a sleep state under the condition that the camera is in a power saving mode.

S403, under the condition of starting a power saving mode, the camera enters a sleep state; the power saving service closes the first camera interface in response to the camera entering a sleep state.

In this embodiment of the present application, the user may be able to turn on the power saving mode for the electronic device by himself, or may be able to automatically turn on the power saving mode when the electronic device detects that the electric quantity is lower than the preset threshold, which is not limited herein. Under the condition of starting the power saving mode, the camera enters a sleep state. The sleep state is a state designed to reduce the consumption of the battery. When the camera enters a sleep state, the power saving service closes the first camera interface, and simultaneously closes the physical camera device through the modules in the FWK layer and the HAL layer. At this time, the camera does not run any background process, and is in an idle state, so that power consumption can be reduced. The user can wake up the camera when clicking or tapping the screen, so that the camera can be in a sleep state.

As shown in fig. 5A, the power saving service may monitor an event that the camera enters a sleep state, and when monitoring that the camera enters the sleep state, close a first camera interface displayed on the back screen in response to the event that the camera enters the sleep state; at this time, the back screen does not display the first camera interface, but only displays a button for switching the screen (for example, a button for switching to the main screen).

S404, the electronic equipment responds to the operation of waking up the camera by the user, and the camera exits from a sleep state; and the power saving service calls a callback function to inform the rear self-timer to manage that the current camera is awakened in response to the camera exiting the sleep state.

In the embodiment of the present application, the operation of waking up the camera by the user may be an operation of clicking or tapping the screen by the user, which is not limited herein. As shown in fig. 5B, the camera exits the sleep state in response to a user waking up the camera. The power saving service can monitor the event that the camera exits the sleep state, and when the event that the camera exits the sleep state is monitored, call a callback function to inform the rear-mounted self-timer to manage that the current camera is awakened.

And S405, when the rear-mounted self-timer management judges that the current display area is not the back screen and the current camera is in the rear-mounted self-timer state, indicating that the current camera mode is wrong, and setting the camera to exit the rear-mounted self-timer state.

In this embodiment of the present application, the post self-timer management needs to determine whether the current display area is a back screen, and whether the current camera is in a post self-timer state. If the current display area is not the back screen and the current camera is in the rear-mounted self-timer state, indicating that the current camera mode is wrong, and setting the camera to exit the rear-mounted self-timer state; if the current display area is the back screen and the current camera is in the rear self-timer state, the camera is kept in the rear self-timer state.

It can be understood that if the post self-timer management determines that the current display area is not the back screen and the current camera is in the post self-timer state, it indicates that the camera is in the sleep state and the user performs the operation of screen switching, for example, the user clicks a button for switching to the main screen, and at this time, the display area is switched to the main screen; or, the user expands the electronic device, at which time the display area is switched to the entire display screen. Since the user performs screen switching (i.e., the display area is switched to the main screen or the entire display screen), the camera interface of the second camera mode (i.e., the second camera interface) should be displayed at the main screen or the entire display screen. However, the camera is still in the rear-mounted self-timer state, the camera interface (i.e., the first camera interface) of the first camera mode is displayed on the main screen or the whole display screen, and the situation that the camera mode is disordered is generated at this time, so that the rear-mounted self-timer management needs to indicate the error of the current camera mode, and the camera is set to exit the rear-mounted self-timer state, so that the situation that the camera mode is disordered due to the fact that the camera interface is displayed in the wrong camera mode is avoided. If the rear self-timer management judges that the current display area is the back screen and the current camera is in the rear self-timer state, the camera is indicated to be in the sleep state, the user does not switch the screen, and the display area is still the back screen, so that the camera does not need to exit from the rear self-timer state.

S406, the user interface module displays a second camera interface on the main screen or the whole display screen.

In the embodiment of the application, when the camera exits from the sleep state, the power saving service starts the physical camera device through the modules in the FWK layer and the HAL layer. The electronic device refreshes the camera mode in response to the camera exiting the post-self-timer state. The user interface module displays a second camera interface on the main screen or the entire display screen according to the current display area. When the rear-mounted self-timer management does not set the camera to exit the rear-mounted self-timer state (namely, the current camera is still in the rear-mounted self-timer state), the camera mode does not need to be refreshed at the moment, and the user interface module displays a first camera interface on the back screen. Based on the mode, the rear-mounted self-timer function can be realized when the camera is in the power saving mode, and meanwhile, the condition that the camera mode is disordered when the camera is awakened is avoided.

1. Under the condition that the camera is in a rear-mounted self-timer state, the electronic equipment starts a power saving mode, and screen switching is performed when the camera is in a dormant state.

Based on the foregoing, a method for switching camera modes provided in the embodiments of the present application is further described in detail below. As shown in fig. 6, the camera mode switching method includes the following steps S601 to S603. The method execution body shown in fig. 6 may be the above-mentioned electronic device. Alternatively, the method execution body shown in fig. 6 may be a chip in the electronic device, which is not limited in the embodiment of the present application. Fig. 6 illustrates an example of an execution body of the method of the electronic device. The electronic equipment comprises a display screen and a rear camera, wherein the display screen comprises a main screen and a back screen, and the main screen and the back screen are two display areas of the same display screen; when the electronic equipment is in a folded state, the main screen and the back screen face opposite directions; when the electronic equipment is in an unfolding state, the main screen and the back screen face the same direction, and the display area is the whole display screen; the rear camera is located in the back area of the main screen, and the direction of the rear camera is opposite to that of the main screen.

S601, at a first time point, the electronic device responds to a power saving mode to enable a camera of the electronic device to enter a sleep state.

In the embodiment of the application, a user may start a camera (may also be referred to as a camera application) to shoot. Before a first time point, the electronic device is in a folded state, the back screen displays a first camera interface, and the camera is in a rear-mounted self-timer state (shown in fig. 1D); the first camera interface is a camera interface in a first camera mode (as shown in fig. 1C (a)), and the rear self-timer state is a state in which a shooting picture acquired by a rear camera is displayed on a back screen.

At the first time point, the power saving mode of the electronic device can be a power saving mode of the electronic device which is started by a user, or a power saving mode of the electronic device which is started automatically when the electric quantity detected by the electronic device is lower than a preset threshold value, and the method is not limited. At this point the electronic device will enable the camera to go to sleep. When the camera enters a sleep state, the first camera interface displayed by the back screen is closed, and the physical camera device is also closed. As shown in fig. 5A, only a button for switching the screen (e.g., a button for switching to the main screen) is displayed on the back screen at this time.

In the software architecture of the electronic device, the application layer includes a camera (camera application); camera applications include User Interface (UI) modules, camera interface modules (CameraApi 2 modules), post self-timer management (rearcamselfiedmanager), power saving services (blackscreen service). At the first time point, the specific implementation process of the electronic device in response to the power saving mode enabling the camera of the electronic device to enter the sleep state may refer to the steps S401 to S403, namely: the electronic equipment responds to the operation of starting the camera by a user, and calls a camera interface module to start the camera; when the camera is started, the post self-timer management is initialized; the post self-timer management registers and monitors to the power saving service; under the condition of starting a power saving mode, the camera enters a sleep state; the power saving service closes the first camera interface in response to the camera entering a sleep state.

And S602, under the condition that the camera is in a sleep state, at a second time point, the electronic equipment responds to the operation of switching the screen, and sets the display area as a main screen or an entire display screen.

In the embodiment of the application, under the condition that the camera is in a sleep state, the user performs screen switching operation on the electronic equipment at a second time point; and the electronic equipment responds to the operation of switching the screen, and sets the display area as a main screen or an entire display screen. The operation of switching the screen may be, but not limited to, clicking a button displayed on the back screen to switch to the main screen (as shown in fig. 5A), expanding the electronic device by the user, or switching other screens. Wherein the second point in time is later than the first point in time.

In one possible implementation manner, when the electronic device sets the display area to be the main screen or the whole display screen in response to the operation of switching the screen at the second time point, the following two cases may be included in a specific implementation manner.

Case 1: setting a display area as a main screen in response to an operation of switching the screen under the condition that the electronic equipment is in a folded state at a second time point; the operation of the switching screen is a click operation of a screen switching button displayed on the back screen.

As shown in fig. 7A, after the user clicks the screen switching button displayed on the back screen (i.e., the button for switching to the home screen), the electronic device sets the display area as the home screen, and at this time, the back screen does not display the camera interface, nor the screen switching button; the home screen does not display a camera interface, but only displays another screen switch button (i.e., a button to switch to the back screen).

Case 2: when the electronic equipment is in a folded state at a second time point, responding to the operation of switching the screen, and setting a display area as the whole display screen; the operation of the switching screen is an operation of expanding the electronic device.

As shown in fig. 7B, after the user expands the folded electronic device at the second time point, the electronic device forcibly sets the display area to be the whole display screen, and at this time, the camera interface is not displayed on the whole display screen.

S603, at a third time point, the electronic equipment responds to the operation of waking up the camera, enables the camera to exit from a sleep state, and based on the display area not being a back screen, the camera is in a rear self-timer state, the camera is set to exit from the rear self-timer state, and a second camera interface is displayed on the main screen or the whole display screen.

In the embodiment of the application, at the third time point, the user may wake up the camera by clicking the screen or tapping the screen; the electronic equipment responds to the operation of waking up the camera and enables the camera to exit from a sleep state; meanwhile, when the current display area is judged not to be the back screen and the camera is in the rear-mounted self-timer state, the electronic equipment needs to set the camera to exit the rear-mounted self-timer state, and meanwhile, the physical camera equipment is started, and a second camera interface is displayed on the main screen or the whole display screen. Wherein the second camera interface is a camera interface of a second camera mode (as shown in (b) of fig. 1C or (C) of fig. 1C), and the first camera mode and the second camera mode are different; the third point in time is later than the second point in time.

That is, if the electronic device determines that the current display area is not the back screen and the current camera is in the rear self-timer state, it indicates that the user performs the screen switching operation while the camera is in the sleep state. Since the user performs screen switching (i.e., the display area is switched to the main screen or the entire display screen), a camera interface of the second camera mode (i.e., a second camera interface) should be displayed at this time. However, the camera is still in the rear-mounted self-timer state, and the camera interface of the first camera mode (i.e., the first camera interface) is displayed on the main screen or the whole display screen, so that the situation of disordered camera mode occurs. Therefore, the electronic device needs to refresh the camera mode, and sets the camera to exit the post-self-timer state so as to avoid the situation that the camera mode is disordered due to the fact that the camera interface is displayed in the wrong camera mode.

For a specific implementation process, reference may be made to steps S404 to S406 described above, that is, the electronic device responds to the operation of waking up the camera by the user, and the camera exits from the sleep state; the power saving service calls a callback function to inform the rear-mounted self-timer to manage that the current camera is awakened in response to the camera exiting from the sleep state; when the rear self-timer management judges that the current display area is not a back screen and the current camera is in a rear self-timer state, indicating that the current camera mode is wrong, and setting the camera to exit the rear self-timer state; the user interface module displays the second camera interface on the main screen or the entire display screen.

For example, suppose that the user clicks a screen switch button displayed on the back screen (i.e., a button to switch to the main screen), at which point the back screen does not display a camera interface nor a screen switch button, as shown in fig. 7A; the home screen does not display a camera interface, but only displays another screen switch button (i.e., a button to switch to the back screen). As shown in fig. 8A, the user may wake up the camera by clicking on the home screen, where the electronic device displays a second camera interface.

For another example, assume that the user expands the folded electronic device, at which time the electronic device forcibly sets the display area to the entire display screen, and the camera interface is not displayed on the entire display screen, as shown in fig. 7B. As shown in fig. 8B, the user may wake up the camera by clicking on the screen and the electronic device displays a second camera interface throughout the display screen.

In one possible implementation, the method further includes: at a fourth time point, the electronic equipment responds to the power saving mode starting to enable a camera of the electronic equipment to enter a sleep state; when the camera enters a sleep state, a first camera interface displayed by the back screen is closed; before a fourth time point, the electronic equipment is in a folded state, the back screen displays a first camera interface, and the camera is in a rear-mounted self-timer state; under the condition that the camera is in a sleep state, at a fifth time point, the electronic equipment responds to the operation of waking up the camera, the display area is a back screen, the camera is in a rear self-timer state, and a first camera interface is displayed on the back screen; the fourth time point is later than the third time point, and the fifth time point is later than the fourth time point.

It is understood that before the fourth point in time, the user switches the camera to the post-self-timer state again. Under the condition that the camera is in the rear-mounted self-timer state, the electronic equipment starts a power saving mode, if the electronic equipment judges that the current display area is the back screen when the camera is awakened, and the current camera is in the rear-mounted self-timer state, the fact that the camera is in the sleep state does not carry out screen switching operation is indicated, the current display area is still the back screen, a camera interface does not need to be refreshed, and the first camera interface can be directly displayed on the back screen. Specific implementation may refer to the following description in fig. 10, which is not described herein.

In one possible implementation, the method further includes: starting from a third time point, enabling a camera of the electronic equipment to enter a sleep state again after a preset time period; setting a display area as a back screen in response to an operation of switching the screen to the back screen at a sixth time point under the condition that the camera is in a sleep state; at a seventh time point, responding to the operation of waking up the camera, enabling the camera to exit from a sleep state, and based on the display area being a back screen, setting the camera to enter a rear-mounted self-timer state, and displaying a first camera interface on the back screen, wherein the camera is not in the rear-mounted self-timer state; the sixth time point is later than the third time point, and the seventh time point is later than the sixth time point. Based on this, it is possible to avoid a situation in which the camera mode is disordered when waking up the camera. The preset time period may be a time period set by a user or a manufacturer, and after the camera is awakened, the camera enters a sleep state again after the preset time period.

Illustratively, as shown in fig. 9A, after the user wakes up the camera by clicking or tapping the home screen at a third point in time, a second camera interface is displayed on the home screen. From the third time point, the camera can reenter the sleep state after the preset time period so as to save the electric quantity. Under the condition that the camera is in a sleep state, at a sixth time point, the user performs the operation of switching the screen to the back screen (namely, clicks a button for switching to the back screen), the electronic equipment sets a display area to the back screen, and at the moment, the main screen does not display a camera picture and does not display the button for switching to the back screen; the back screen does not display the camera interface, but only displays the button to switch to the home screen. When the user wakes up the camera by clicking the back screen or touching the back screen at the seventh time point, the electronic equipment responds to the operation of waking up the camera and enables the camera to exit from the sleep state; meanwhile, when the current display area is judged to be the back screen and the camera is not in the rear-mounted self-timer state, the electronic equipment needs to set the camera to enter the rear-mounted self-timer state and display a first camera interface on the back screen.

In one possible implementation, the method further includes: starting from a third time point, enabling a camera of the electronic equipment to enter a sleep state again after a preset time period; under the condition that the camera is in a sleep state, at an eighth time point, responding to an operation of waking up the camera, enabling the camera to exit the sleep state, and displaying a second camera interface on a main screen or the whole display screen based on the fact that the display area is not a back screen and the camera is not in a rear-mounted self-timer state; the eighth time point is later than the third time point. Based on this, it is possible to avoid a situation in which the camera mode is disordered when waking up the camera. The preset time period may be a time period set by a user or a manufacturer, and after the camera is awakened, the camera enters a sleep state again after the preset time period.

Illustratively, as shown in fig. 9B, after the user wakes up the camera by clicking or tapping the home screen at a third point in time, a second camera interface is displayed on the home screen. From the third time point, the camera can reenter the sleep state after the preset time period so as to save the electric quantity. Under the condition that the camera is in a sleep state, when a user wakes up the camera by clicking or tapping the main screen at an eighth time point, the electronic equipment responds to the operation of waking up the camera and enables the camera to exit the sleep state; meanwhile, when the current display area is judged not to be the back screen and the camera is not in the rear-mounted self-timer state, the fact that the user does not execute the operation of switching the screen in the process of re-entering the sleep state to being awakened again is indicated, and therefore the camera interface does not need to be refreshed, and the second camera interface can be directly displayed on the main screen.

In one possible implementation manner, at a first time point, the display area is a back screen, and the electronic device is in a folded state; at a second time point, the operation of the switching screen is the operation of unfolding the electronic equipment, the display area is the whole display screen, and the electronic equipment is in an unfolded state; the method further comprises the steps of: starting from a third time point, enabling a camera of the electronic equipment to enter a sleep state again after a preset time period; under the condition that the camera is in a sleep state, at a ninth time point, responding to the operation of the folding electronic equipment, setting the current display area to be restored to the last display area, wherein the last display area is a back screen; based on the display area, recovering to the back screen, and setting the camera to reenter the rear self-timer state when the camera is not in the rear self-timer state; the ninth time point is later than the third time point. Based on this, it is possible to avoid a situation in which the camera mode is disordered when waking up the camera. The preset time period may be a time period set by a user or a manufacturer, and after the camera is awakened, the camera enters a sleep state again after the preset time period.

As shown in fig. 9C, at a first time point, the electronic device is in a folded state, and the display area is a back screen; at a second point in time, the user expands the electronic device in the collapsed state, at which time the display area is set to the entire display screen. And after the camera is awakened through the operation of clicking the screen or tapping the screen at the third time point, displaying a second camera interface on the whole display screen, wherein the electronic equipment is in an unfolding state. From the third time point, the camera can reenter the sleep state after the preset time period so as to save the electric quantity. Under the condition that the camera is in a sleep state, the user refolding the unfolded electronic equipment at a ninth time point, and the electronic equipment needs to restore the current display area to the previous display area, namely a back screen; when the electronic equipment judges that the current display area is restored to the back screen and the camera is not in the rear-mounted self-timer state, the camera needs to be reset to enter the rear-mounted self-timer state.

Therefore, based on the method described in the application, the first camera mode adopted by the back screen display camera interface is different from the second camera mode adopted by the main screen or the whole display screen display camera interface, and when the electronic equipment is in the power saving mode, whether the current display area is switched needs to be judged when the camera is awakened, if the user performs the operation of switching the screen, the camera mode needs to be refreshed when the camera is awakened, the situation that the camera interface is displayed in an error camera mode to cause the disorder of the camera mode is avoided, and the back self-timer function can be supported when the camera is in the power saving mode.

2. Under the condition that the camera is in a rear-mounted self-timer state, the electronic equipment starts a power saving mode, and screen switching is not performed when the camera is in a dormant state.

Based on the foregoing, another method for switching camera modes provided in the embodiments of the present application is described in further detail below. As shown in fig. 10, the method of switching the camera mode includes the following steps S1001 and S1002. The method execution body shown in fig. 10 may be the above-mentioned electronic device. Alternatively, the method execution body shown in fig. 10 may be a chip in the electronic device, which is not limited in the embodiment of the present application. Fig. 10 illustrates an execution body of the method of the electronic device as an example. The electronic equipment comprises a display screen and a rear camera, wherein the display screen comprises a main screen and a back screen, and the main screen and the back screen are two display areas of the same display screen; when the electronic equipment is in a folded state, the main screen and the back screen face opposite directions; when the electronic equipment is in an unfolding state, the main screen and the back screen face the same direction, and the display area is the whole display screen; the rear camera is located in the back area of the main screen, and the direction of the rear camera is opposite to that of the main screen.

S1001, at a fourth time point, the electronic device responds to the power saving mode to enable the camera of the electronic device to enter a sleep state.

In the embodiment of the application, when the camera enters a sleep state, a first camera interface displayed on the back screen is closed, and meanwhile, the physical camera equipment is also closed; before a fourth time point, the electronic equipment is in a folded state, the back screen displays a first camera interface, and the camera is in a rear self-timer state. Specific implementation may refer to the description of step S601 at that time, and will not be described herein.

And S1002, under the condition that the camera is in a sleep state, at a fifth time point, the electronic equipment responds to the operation of waking up the camera, the display area is a back screen, the camera is in a rear self-timer state, and a first camera interface is displayed on the back screen.

In the embodiment of the present application, the fifth time point is later than the fourth time point. Under the condition that the camera is in the rear-mounted self-timer state, the electronic equipment starts a power saving mode, if the electronic equipment judges that the current display area is the back screen when the camera is awakened, and the current camera is in the rear-mounted self-timer state, the fact that the camera is in the sleep state does not perform screen switching operation is indicated, the current display area is still the back screen, physical camera equipment can be started, and a first camera interface is directly displayed on the back screen.

As shown in fig. 5B, at a fourth time point, the user turns on the power saving mode, the camera of the electronic device enters a sleep state, and when the camera enters the sleep state, the first camera interface displayed on the back screen is turned off, and only a button for switching to the main screen is displayed; at a fifth time point, the user can click the back screen to wake up the camera, at this time, the electronic device judges that the current display area is the back screen, and the current camera is in a rear self-timer state, which indicates that the user does not perform screen switching operation when the camera is in a sleep state, and the first camera interface is directly displayed on the back screen.

Therefore, based on the method described in the application, the first camera mode adopted by the back screen display camera interface is different from the second camera mode adopted by the main screen or the whole display screen display camera interface, and when the electronic equipment is in the power saving mode, whether the current display area is switched needs to be judged when the camera is awakened, if the user does not execute the operation of switching the screen, the camera mode does not need to be refreshed when the camera is awakened, so that the power consumption is saved.

It should be noted that the method for switching camera modes provided in the present application may also be applicable to other applications with high power consumption, such as game applications, video applications, and the like. The method and the device can be particularly applied to a scene of state disorder when the application enters the power saving mode and exits the power saving mode. For example, for a game application, when the game application enters a power saving mode and the electronic device is unfolded, the screen state changes, and when the electronic device exits the power saving mode, the interface can be refreshed to adapt to a new layout similar to the switching method of the camera mode, which is not described herein.
