Technical Field

[0002] The present application relates to the field of electronic technology, and in particular to a photographing method and electronic equipment. Background Art

[0003] As people's requirements for mobile phone display and portability gradually increase, foldable screen mobile phones are becoming more and more popular among users.

[0004] Folding screen phones include front cameras and rear cameras. Generally, when using a folding screen phone to take selfies, you can only use the front camera, which has poor shooting effects.

[0005] Summary of the Invention

[0006] The present application provides a photographing method, device, electronic device, chip, computer-readable storage medium and computer program product, which can improve selfie effects and enhance user experience.

[0007] In a first aspect, the present application provides a photographing method, which is performed by an electronic device, the electronic device including a foldable screen and a rear camera, the foldable screen including a first screen and a second screen, the rear camera and the first screen being arranged opposite each other, the first screen and the second screen being on the same side when the electronic device is in an unfolded state, and the second screen and the rear camera being on the same side when the electronic device is in a folded state, the method comprising:

[0008] When the electronic device is in a folded state, the first screen is in a bright state, and the second screen is in an off state, a first operation of the user is received; in response to the first operation, the first screen is controlled to be off, and the second screen is controlled to be brightened, and a first photo preview interface is displayed through the second screen, wherein the first photo preview interface includes an image obtained through the rear camera.

[0009] The electronic device may be an outward-folding screen device, such as an outward-folding screen mobile phone. The first screen is also referred to as the main screen, and the second screen is also referred to as the secondary screen. Optionally, the first screen and the second screen may be two parts of a folding screen.

[0010] The first photo preview interface is also the photo preview interface in the rear selfie scene.

[0011] Optionally, the first operation can be any one of the following operations: clicking the rear selfie control, flipping the electronic device, clicking the selfie icon or selfie option in the main interface, exiting the camera settings interface after turning on the rear selfie function in the camera settings interface, or setting the default selfie mode to rear selfie in the camera settings interface and then exiting the camera settings interface, etc.

[0012] The first aspect provides a photographing method, in which, when the electronic device is in a folded state, the first screen is in a bright state, and the second screen is in an off state, the user can trigger the rear selfie function through a first operation, that is, the first screen of the electronic device is off, the second screen is on, and the first photographing preview interface in the rear selfie scene is displayed through the second screen. Since the second screen and the rear camera are on the same side in the folded state, the user can use the rear camera to take pictures of people or things on the side of the user (i.e., selfies), and view the first photographing preview interface on the second screen, which is convenient for the user to take selfies. Moreover, the image taken by the rear camera is displayed in the first photographing preview interface, that is, in the rear selfie scene, the image is obtained through the rear camera. The specifications and hardware configuration of the rear camera are relatively high, the image quality captured is relatively high, the shooting effect is relatively good, and the user experience can be improved.

[0013] In a possible implementation, before receiving the user's first operation, the method further includes: displaying a second photo preview interface through the first screen, the second photo preview interface including a first control; and the first operation is an operation acting on the first control.

[0014] The second photo preview interface can be a photo preview interface for a rear-camera non-selfie scene or a front-camera selfie scene. In other words, the user can enter the rear-camera selfie function by performing the first operation on the first control in a rear-camera non-selfie scene; or the user can enter the rear-camera selfie function by performing the first operation on the first control in a front-camera selfie scene.

[0015] The operation acting on the first control may, for example, be clicking on the first control. When the user enters the rear-mounted selfie function in a rear-mounted non-selfie scenario, the first control may, for example, be the rear-mounted selfie control in the photo preview interface in the rear-mounted non-selfie scenario, and the operation acting on the first control may be clicking on the rear-mounted selfie control. When the user enters the rear-mounted selfie function in a front-mounted selfie scenario, the first control may, for example, be the setting control or the rear-mounted selfie control in the photo preview interface in the rear-mounted non-selfie scenario. When the first control is a setting control, the operation acting on the first control may sequentially include clicking on the setting control (entering the camera setting interface after clicking), turning on the rear-mounted selfie function switch or selecting the selfie mode as the rear-mounted selfie, and exiting the camera setting interface. When the first control is a rear-mounted selfie control, the first operation may be clicking on the rear-mounted selfie control.

[0016] In this implementation, the user can quickly enter the rear selfie function by performing the first operation on the first control, which facilitates operation and improves user experience.

[0017] In one possible implementation, the electronic device further includes a front camera, which is located on the same side as the first screen, and the second photo preview interface includes an image obtained through the rear camera or an image obtained through the front camera.

[0018] When the second photo preview interface includes an image captured by the rear camera, it corresponds to entering the rear selfie function from the rear non-selfie scene, and the second photo preview interface is the photo preview interface for the rear non-selfie scene. When the second photo preview interface includes an image captured by the front camera, it corresponds to entering the rear selfie function from the front selfie scene, and the second photo preview interface is the photo preview interface for the front selfie scene.

[0019] In this implementation, users can enter the rear selfie function from the front selfie scene, and can also enter the rear selfie function from the rear selfie scene, providing users with multiple ways to enter the rear selfie function, facilitating user operation and improving user experience.

[0020] In one possible implementation, in response to a first operation, the first screen is controlled to turn off, and the second screen is controlled to turn on, and a first photo preview interface is displayed through the second screen, including: in response to the first operation, a first flip guide interface is displayed through the first screen, and the first flip guide interface is used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, the first screen is controlled to turn off, and the second screen is controlled to turn on, and the first photo preview interface is displayed through the second screen.

[0021] In this implementation, when entering the rear selfie function, before controlling the screen switch, a first flip guide interface is first displayed to guide the user to flip the electronic device, so that the user can know how to use the rear selfie function and improve the user experience.

[0022] Optionally, while the second screen displays the first flip guide interface, the electronic device can block the touch function of the first screen and the second screen. That is, the touch function of the first screen and the second screen is blocked within a preset time (for example, 3 seconds) after the user performs the first operation. This can prevent the user from accidentally touching the screen and affecting the entry into the rear selfie function, thereby improving the user experience.

[0023] In a possible implementation, the second photo preview interface includes an image acquired through the rear camera, and the second photo preview interface also includes guidance information, where the guidance information is used to guide the user to click the first control.

[0024] In this implementation, the user is guided to use the rear selfie function by displaying guidance information, which makes it easier for the user to understand how to use the rear selfie function and improves the user experience.

[0025] In one possible implementation, the second photo preview interface includes an image captured by the rear camera, and the method further includes: in response to a second operation performed by the user on the first control, adding a second control to the second photo preview interface.

[0026] Optionally, the second control can be a swipe up operation on the area where the first control is located. The second control is also the flip camera control. Click the second control to enter the front selfie scene.

[0027] In this implementation, the user triggers the display of a second control in the interface through a second operation. In this way, the interface includes both a first control for entering the rear-camera selfie function and a second control for entering the front-camera selfie scene. In this way, the user can choose between rear-camera selfie and front-camera selfie according to usage needs, which is convenient for user use and improves user experience.

[0028] In one possible implementation, the second photo preview interface includes an image captured by the rear camera, and the second photo preview interface also includes a setting control. The method also includes: when the second photo preview interface is displayed on the first screen, in response to a third operation performed by the user on the setting control, displaying a camera setting interface through the first screen, the camera setting interface including setting options for the selfie mode; in response to the user's operation on the setting option, displaying a first pop-up window, the first pop-up window including a front selfie option and a rear selfie option, and the rear selfie option is in a selected state; in response to the user's operation on the front selfie option, the rear selfie option is displayed as unselected, and the front selfie option is displayed as selected; in response to the user's operation of closing the first pop-up window and exiting the camera setting interface, displaying a third photo preview interface through the first screen, the third photo preview interface including the image captured by the rear camera and the second control.

[0029] That is, in the rear-facing non-selfie scenario, the user selects the front-facing selfie option in the first pop-up window, changing the default selfie mode from rear-facing selfie to front-facing selfie. After the user exits the camera settings interface, the shooting scene remains the rear-facing non-selfie scene, but the controls displayed in the interface change to the second control (camera switch control). The user clicks the camera switch control to enter the front-facing selfie scenario. In this implementation, the user can independently select the default selfie mode, and the controls in the photo preview interface change based on the user's selection, making the interface display more consistent with the user's preferences and improving the user experience.

[0030] In a possible implementation, the method further includes: in response to the user clicking the second control, displaying a fourth photo preview interface through the first screen, where the fourth photo preview interface includes an image acquired through the front camera.

[0031] The fourth photo preview interface is also the photo preview interface in the front selfie scene.

[0032] In one possible implementation, the fourth photo preview interface includes a first control, and the method further includes: in response to a fourth operation performed by the user on the first control in the fourth photo preview interface, displaying a first flip guide interface through the first screen, the first flip guide interface being used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the first photo preview interface through the second screen.

[0033] Optionally, the first control may be a rear selfie control or a setting control. The fourth operation may be an operation such as clicking the rear selfie control or setting a selfie mode through the setting control.

[0034] In a possible implementation, before receiving the first operation of the user, the method further includes: displaying a second photo preview interface through the first screen; the first operation is an operation of flipping the electronic device.

[0035] In this implementation, the user can enter the rear selfie function by flipping the electronic device, without the user having to perform operations such as clicking on the rear selfie control in the interface. The rear selfie function can be entered quickly and conveniently, thereby improving the intelligence of the electronic device and thus improving the user experience.

[0036] In a possible implementation, the second photo preview interface includes an image acquired through the rear camera.

[0037] That is to say, users can enter the rear selfie function from the rear selfie scene by flipping the electronic device.

[0038] In a possible implementation, the shooting mode in the first photo preview interface is the same as the shooting mode in the second photo preview interface.

[0039] For example, if the user selects portrait mode in the first photo preview interface, the shooting mode in the second photo preview interface will also be portrait mode, which can inherit the user's selection and improve the user experience. Of course, after entering the rear selfie function, the user can also switch the shooting mode to other modes as needed.

[0040] In one possible implementation, before receiving the user's first operation, the method also includes: displaying a main interface through the first screen, the main interface including an icon of a camera application; in response to the user long pressing the icon of the camera application, displaying a first service card through the first screen, the first service card including a selfie option; the first operation is clicking the selfie option.

[0041] In this implementation, the user can enter the rear selfie function through the selfie option in the main interface, without the user having to open the second photo preview interface, or click on the rear selfie control or setting control in the second photo preview interface, thereby simplifying the user's operation process of entering the rear selfie function and improving the user experience.

[0042] In one possible implementation, before receiving the user's first operation, the method also includes: displaying a main interface through the first screen, the main interface including an icon of a camera application; in response to the user clicking the icon of the camera application, displaying a first service card through the first screen, the first service card including a selfie option; in response to the user dragging the selfie option to the main interface, displaying a selfie icon corresponding to the selfie option in the main interface; the first operation is clicking the selfie icon.

[0043] In this implementation, the user can enter the rear selfie function through the selfie icon in the main interface, without the user having to open the second photo preview interface, or click on the rear selfie control or setting control in the second photo preview interface, thereby simplifying the user's operation process of entering the rear selfie function and improving the user experience.

[0044] In one possible implementation, in response to a first operation, the first screen is controlled to turn off, and the second screen is controlled to turn on, and a first photo preview interface is displayed through the second screen, including: in response to the first operation, starting a camera application; displaying a first flip guide interface through the first screen, the first flip guide interface is used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, the first screen is controlled to turn off, and the second screen is controlled to turn on, and the first photo preview interface is displayed through the second screen.

[0045] In this implementation, the user is guided to use the rear selfie function by displaying the first flip guide interface, which helps the user understand how to use the rear selfie function and improves the user experience.

[0046] In one possible implementation, the method also includes: when the first photo preview interface is displayed on the second screen, in response to the fourth operation performed by the user on the first screen, exiting the camera application to the background; controlling the second screen to turn off, and controlling the first screen to turn on; in response to the fourth operation performed by the user on the first screen, controlling the camera application to run in the foreground, and displaying the first flip guide interface through the first screen; after the first flip guide interface is displayed for a first preset time, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the first photo preview interface through the second screen.

[0047] The fourth operation is to exit the camera app to the background. In this implementation, if the user exits the camera app to the background, the electronic device can retain the running camera app. When the user re-launches the camera app, the rear-facing selfie function continues to function. This eliminates the need for the user to repeatedly access the rear-facing selfie function, simplifying user operations and improving the user experience.

[0048] In one possible implementation, the first photo preview interface includes a third control, and the third control includes a thumbnail. The method also includes: when the first photo preview interface is displayed on the second screen, in response to the user clicking the third control, the first interface is displayed through the second screen, and the first interface includes an image corresponding to the thumbnail.

[0049] The third control is the thumbnail of the image taken by the user in the photo preview interface. The first interface is the image preview interface in the folded state.

[0050] In this implementation, while using the rear-mounted selfie function, the user can view the captured image through the image thumbnail in the first photo preview interface. The image can be displayed on the second screen. This allows the user to view the image at any time without exiting the rear-mounted selfie function, which is convenient for the user and improves the user experience.

[0051] In one possible implementation, the method also includes: when the first interface is displayed on the second screen, in response to the user unfolding the electronic device to the unfolded state, controlling the first screen to light up, and displaying the second interface through the first screen and the second screen together, the second interface including an image corresponding to the thumbnail.

[0052] The second interface is the image preview interface in the expanded state.

[0053] In this implementation, if the rear-mounted selfie function is enabled and the user is viewing an image on the second screen and then unfolds the electronic device to the unfolded state, the image is displayed on both the first and second screens. This means that while viewing an image on the second screen, the user can unfold the foldable screen at any time to display the image simultaneously on the first and second screens, enabling large-scale image previews, facilitating user experience and enhancing user experience.

[0054] In one possible implementation, the method also includes: when the first photo preview interface is displayed on the second screen, in response to the user unfolding the electronic device to the unfolded state, controlling the first screen to light up, and jointly displaying the fifth photo preview interface through the first screen and the second screen, the fifth photo preview interface including the image obtained by the rear camera.

[0055] The fifth photo preview interface is the photo preview interface for the rear non-selfie scene in the expanded state.

[0056] In this implementation, when using the rear-camera selfie function, if the user unfolds the electronic device, the camera application exits the rear-camera selfie function and enters the rear-camera non-selfie mode in the unfolded state. When the user unfolds the electronic device to the unfolded state, it indicates that the user no longer needs the rear-camera selfie function, so directly entering the unfolded state rear-camera shooting mode is likely to meet user needs and improve the user experience.

[0057] In one possible implementation, the first photo preview interface includes a second control and a fourth control, and the method further includes: when the first photo preview interface is displayed on the second screen, in response to the user clicking the fourth control or the second control, a second flip guide interface is displayed through the second screen, and the second flip guide interface is used to guide the user to flip the electronic device; after the second flip guide interface is displayed for a second preset time, the second screen is controlled to turn off, and the first screen is controlled to turn on, and the second photo preview interface is displayed through the first screen, and the second photo preview interface includes an image obtained through the rear camera.

[0058] The second control may be a flip camera control. The fourth control may be a home screen switch control or a rear selfie exit control.

[0059] While using the rear-camera selfie function, users can exit it using the home screen switch, flip camera control, or rear selfie exit control in the first photo preview interface. After exiting the rear-camera selfie function, the camera app enters the rear non-selfie mode in the folded state. The electronic device turns off the second screen, lights up the first screen, and displays the second photo preview interface on the first screen. In other words, users can exit the rear-camera selfie function at any time while using it, making it easier for users to operate and use, and improving the user experience.

[0060] In a second aspect, the present application provides a device, which is included in an electronic device and has the function of implementing the electronic device behavior described in the first aspect and possible implementations of the first aspect. The function can be implemented through hardware or through hardware executing corresponding software implementations. The hardware or software includes one or more modules or units corresponding to the above functions. For example, a receiving module or unit, a processing module or unit, etc.

[0061] In a third aspect, the present application provides an electronic device, which includes: a processor, a memory, and an interface; the processor, the memory, and the interface cooperate with each other so that the electronic device executes any one of the methods in the technical solution of the first aspect.

[0062] In a fourth aspect, the present application provides a chip including a processor, wherein the processor is configured to read and execute a computer program stored in a memory to perform the method of the first aspect and any possible implementation thereof.

Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0094] Foldable screen mobile phones are mainly divided into external foldable screen mobile phones and internal foldable screen mobile phones. Both external foldable screen mobile phones and internal foldable screen mobile phones can include several forms, including folding state, stand state and unfolded state. Among them, the stand state refers to the form between the folded state and the unfolded state. External foldable screen mobile phones and internal foldable screen mobile phones both include foldable screens. In the unfolded state, the foldable screen is in the unfolded state. In the unfolded state of the external foldable screen mobile phone, when the foldable screen faces the user, fold the phone to the side away from the user (called outward folding), the form of the external foldable screen mobile phone changes to the stand state, and continues to fold outward to change to the folded state. In the unfolded state of the internal foldable screen, when the foldable screen faces the user, fold the phone to the side close to the user (called inward folding), the form of the external foldable screen mobile phone changes to the stand state, and continues to fold inward to change to the folded state.

[0095] The embodiment of the present application mainly uses a foldable screen mobile phone as an example to illustrate the method of taking pictures. For ease of understanding, the structure of the foldable screen mobile phone is first introduced.

[0096] For example, Figure 1 shows the front and back views of a foldable phone 10 in its unfolded state. The foldable phone 10 is an external foldable phone. As shown in Figure 1 , the foldable phone 10 includes a first structural member 11, a second structural member 12, and a connecting assembly 13 (located at the position indicated by the dashed line in Figure 1 ) connecting the first and second structural members 11, 12. The connecting assembly 13 enables the first and second structural members 11, 12 to be flipped and folded.

[0097] The first structural member 11 may include a main display screen (hereinafter referred to as the main screen, also referred to as the first screen) 111, a first back housing 112, and a raised portion 113. The main screen 111 is provided with a front camera 1111. The first back housing 112 and the raised portion 113 are provided on the back of the main screen 111. The raised portion 113 may be provided with a rear camera 1122.

[0098] The second structural member 12 may include a sub-display screen (hereinafter referred to as sub-screen, also referred to as second screen) 121 and a second back shell 122. The second back shell 122 is provided at the back of the sub-screen 121.

[0099] During use, the angle between the first structural member 11 and the second structural member 12 is changed by the connecting assembly 13 to achieve various configurations of the foldable screen mobile phone 10. It is understood that the secondary screen 121 and the main screen 111 can actually be an integrally formed flexible display screen (i.e., a foldable screen). When the foldable screen mobile phone 10 is folded via the connecting assembly 13, the connecting assembly 13 divides the screen into two parts: the main screen 111 and the secondary screen 121. The main screen 111 and the rear camera 1122 are located on the same side of the connecting assembly.

[0100] As shown in Figure 1, when the angle between the first structural member 11 and the second structural member 12 is approximately 180°, the foldable screen mobile phone 10 is in the unfolded state. At this time, the surface of the first back shell 112 of the first structural member 11 and the surface of the second back shell 122 of the second structural member 12 are approximately in the same plane. The surfaces of the main screen 111 and the secondary screen 121 are approximately in the same plane, that is, the main screen 111 and the secondary screen 121 are on the same side. In the unfolded state, the light emitting direction of the main screen 111 and the secondary screen 121 is the same as the light incoming direction of the rear camera 1122. In the unfolded state, the foldable screen mobile phone 10 displays the content to be displayed simultaneously through the main screen 111 and the secondary screen 121. Optionally, in the unfolded state, the main screen 111 and the secondary screen 121 can jointly display the interface of the same application, or can display the interfaces of different applications in split screens.

[0101] When the foldable screen mobile phone 10 is in the unfolded state shown in Figure 1, and the main screen 111 and the sub-screen 121 are both on, the user can gradually fold the foldable screen mobile phone 10 outward (in the direction indicated by the arrow in Figure 1) to put the foldable screen mobile phone 10 into the stand state, as shown in Figure 2.

[0102] When the foldable phone 10 is in the stand position, if the angle between the first and second structural members 11, 12 is greater than 45°, both the primary and secondary screens remain illuminated, as shown in Figure 2. When the angle between the first and second structural members 11, 12 gradually decreases to approximately 45°, the secondary screen 121 turns off, leaving only the primary screen 111 illuminated, displaying the desired content. During the subsequent folding process, only the primary screen 111 remains illuminated until the angle between the first and second structural members 11, 12 reaches approximately 0°, resulting in the folded position shown in Figure 3.

[0103] As shown in Figures (a) and (b) of Figure 3, when the foldable screen mobile phone 10 is in the folded state, the surface of the secondary screen 121 of the second structural member 12 is approximately in the same plane as the surface of the raised portion 113 of the first structural member 11. At this time, the secondary screen 121 and the rear camera 1122 are on the same side. In the folded state, the light output direction of the secondary screen 121 is opposite to the light input direction of the rear camera 1122.

[0104] In the folded state, the foldable screen mobile phone 10 displays the required content through the main screen 111, while the secondary screen 121 does not display any content and can be in the off state. It should be noted that when the secondary screen 121 is in the off state, it does not receive touch operations. Therefore, in the folded state, the user performs touch operations through the main screen 111.

[0105] The process of the foldable screen mobile phone 10 gradually unfolding from the folded state to the unfolded state, and the state change of the screen are the reverse process from the unfolded state to the folded state, which will not be repeated.

[0106] With the support of the structure of the foldable screen mobile phone 10 described in Figures 1 to 3 above, in a photo-taking scenario, when the foldable screen mobile phone 10 is in the unfolded state shown in Figure 1, the user can use the rear camera 1122 to take pictures of people or objects around him, and the captured image can be displayed simultaneously on the main screen 111 and the sub-screen 121, as shown in Figure 4 (a). This shooting scenario is also called the rear non-selfie scene in the unfolded state. At the same time, when the foldable screen mobile phone 10 is in the unfolded state shown in Figure 1, the user can also use the front camera 1111 to take a selfie, and the captured image can be displayed simultaneously on the main screen 111 and the sub-screen 121, as shown in Figure 4 (b). This shooting scenario is also called the front selfie scene in the unfolded state.

[0107] When the foldable screen mobile phone 10 is in the folded state as shown in FIG3 , the user can use the rear camera 1122 to take pictures of people or objects around them, and the captured image is displayed on the main screen 111, as shown in FIG5 (a). This shooting scene is also called the rear non-selfie scene in the folded state. When the foldable screen mobile phone 10 is in the folded state as shown in FIG3 , the user can also use the front camera 1111 to take a selfie, and the captured image is displayed on the main screen 111, as shown in FIG5 (b). This shooting scene is also called the front selfie scene in the folded state.

[0108] However, the specifications of the front cameras of mobile phones are generally low, and the image quality and effect obtained by using the front cameras are poor.

[0109] In view of this, an embodiment of the present application provides a method for taking pictures. When a foldable screen mobile phone is in a folded state, when a user uses a foldable screen mobile phone to take pictures, a rear selfie (also called a super selfie) function is provided to the user. After the rear selfie function is enabled, the mobile phone starts the rear camera 1122 to capture images, and the sub-screen 121 lights up. The user can control the photo taking and view the captured images through the sub-screen 121. In this way, the shooting quality and shooting effect of the selfie can be improved, thereby improving the user's shooting experience. In the embodiment of the present application, the scene shot by the rear selfie function can be called a rear selfie scene, and the photo preview interface under the rear selfie scene can be as shown in Figure (c) in Figure 5.

[0110] It is understood that the photographing method provided in the embodiment of the present application can be applied to any electronic device with a foldable screen and a camera application, and is not limited to foldable screen mobile phones. The embodiment of the present application is described using a foldable screen mobile phone as an example.

[0111] For example, FIG6 is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application. The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 124, a sensor module 180, a button 190, a camera 193, and a display screen 194. The sensor module 180 may include an angle sensor 180A, a gyroscope sensor 180B, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a touch sensor 180K, and the like.

[0112] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0113] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). The different processing units may be independent devices or integrated into one or more processors.

[0114] The controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0115] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly retrieve it from the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

[0116] The electronic device 100 implements display functions through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing that connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering.

[0117] Display screen 194 is used to display images, videos, and the like. Display screen 194 includes a display panel. In some embodiments, electronic device 100 may include one or N display screens 194, where N is a positive integer greater than 1. In the embodiment of the present application, N may be equal to 2, meaning electronic device 100 may include two display screens 194, one of which is a primary screen and the other a secondary screen. The primary screen and secondary screen may be connected as one and made of a flexible material.

[0118] The electronic device 100 can implement a shooting function through an ISP, a camera 193, a video codec, a GPU, a display screen 194, and an application processor.

[0119] The ISP processes data fed back by camera 193. For example, when taking a photo, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, which is then passed to the ISP for processing and transformed into a visible image. The ISP can also perform algorithmic optimization on image noise, brightness, and skin tone. It can also optimize parameters such as exposure and color temperature of the captured scene. In some embodiments, the ISP can be located within camera 193.

[0120] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to the ISP for conversion into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1. In the embodiment of the present application, N may be equal to 2, that is, the electronic device 100 may include 2 cameras, one is a front camera and the other is a rear camera. The front camera is arranged on the main screen, and the rear camera is arranged on the raised portion.

[0121] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 via the external memory interface 120 to implement data storage functions. For example, files such as music and videos can be stored on the external memory card.

[0122] The internal memory 124 can be used to store computer executable program codes, which include instructions. The processor 110 executes the instructions stored in the internal memory 124 to execute various functional applications and data processing of the electronic device 100.

[0123] The angle sensor 180A is used to detect the angle between the first structural member and the second structural member, so as to determine whether the electronic device is in a folded state or an unfolded state according to the angle, and then control the states of the main screen and the sub-screen.

[0124] The gyroscope sensor 180B can be used to determine the motion posture of the electronic device 100. The magnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the magnetic sensor 180D to detect the opening and closing of the flip leather case. The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally three axes). The distance sensor 180F is used to measure distance. The electronic device 100 can measure distance through infrared or laser. In some embodiments, when shooting a scene, the electronic device 100 can use the distance sensor 180F to measure distance to achieve fast focus.

[0125] In the embodiment of the present application, one or more of the gyroscope sensor 180B, the magnetic sensor 180D, the acceleration sensor 180E and the distance sensor 180F cooperate to implement flip detection of the electronic device 100, that is, to detect whether the electronic device has been flipped.

[0126] The touch sensor 180K is also called a "touch panel." The touch sensor 180K can be disposed on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen." The touch sensor 180K is used to detect touch operations applied thereto or in the vicinity thereof. The touch sensor can transmit the detected touch operations to the application processor to determine the type of touch event. Visual output related to the touch operations can be provided via the display screen 194. In other embodiments, the touch sensor 180K can also be disposed on the surface of the electronic device 100, in a location different from that of the display screen 194.

[0127] The hardware system of electronic device 100 is described in detail above. The following describes the software system of electronic device 100. The software system can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. In the embodiment of the present application, the layered architecture is used as an example to exemplify the software system of electronic device 100.

[0128] As shown in Figure 7 , a software system using a layered architecture is divided into several layers, each with distinct roles and divisions of labor. Layers communicate with each other via software interfaces. In some embodiments, the software system can be divided into four layers: application layer 210, application framework layer 220, hardware abstraction layer 230, and driver layer 240, from top to bottom. For ease of illustration, Figure 7 also shows the hardware layer 250 of the electronic device.

[0129] The application layer 210 may include camera and gallery applications, as well as calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0130] The application framework layer 220 provides an application access interface and a programming framework for the applications of the application layer 210 .

[0131] For example, the application framework layer 220 includes a camera access interface, which is used to provide camera shooting services through camera management and camera devices.

[0132] The camera management in the application framework layer 220 is used to manage the camera. The camera management can obtain the parameters of the camera, such as determining the working status of the camera.

[0133] The camera device in the application framework layer 220 is used to provide a data access interface between different camera devices and camera management.

[0134] The hardware abstraction layer 230 is used to abstract hardware. For example, the hardware abstraction layer 230 may include a camera hardware abstraction layer and other hardware device abstraction layers. The camera hardware abstraction layer may include camera device 1, camera device 2, etc. The camera hardware abstraction layer may be connected to the camera algorithm library, and the camera hardware abstraction layer may call algorithms in the camera algorithm library.

[0135] The driver layer 240 is used to provide drivers for different hardware devices. For example, the driver layer may include a camera driver, a digital signal processor driver, and a graphics processor driver.

[0136] The hardware layer 250 may include sensors, image signal processors, digital signal processors, graphics processors, and other hardware devices. The sensors may include sensor 1, sensor 2, etc., and may also include depth sensors (time of flight, TOF) and multispectral sensors.

[0137] The following describes the workflow of the software system of the electronic device 100 in conjunction with a photo-taking scenario.

[0138] When a user clicks the touch sensor 180K corresponding to the photo control, the camera app is awakened by the single click and then invokes the various camera devices in the camera hardware abstraction layer through the camera access interface. For example, the camera hardware abstraction layer determines that the current zoom factor is within the zoom factor range of [0.6, 0.9]. Therefore, it issues a command to the camera device driver to invoke the wide-angle camera, and the camera algorithm library begins loading the preset algorithm.

[0139] When a sensor in the hardware layer is called, for example, sensor 1 in the wide-angle camera, it captures a raw image and sends it to the image signal processor for preliminary processing, such as registration. This processed image is then returned to the hardware abstraction layer by the camera device driver. It is then processed using the pre-set algorithms in the camera algorithm library to produce the captured image (i.e., a photo). The resulting image is then sent back to the camera application via the camera hardware abstraction layer and the camera access interface for display and storage.

[0140] It should be noted that the above process describes the software system's workflow after the user clicks the photo control. In the photo preview scenario, the electronic device's software system's workflow for acquiring images is similar to the above process, except that the user doesn't click the photo control, so the image doesn't need to be stored and is simply displayed on the photo preview interface.

[0141] Below, in combination with the application scenarios and accompanying drawings, taking the electronic device as an outward folding screen mobile phone as an example, the photo-taking method provided in the embodiment of the present application is specifically explained.

[0142] To facilitate understanding, several terms involved in the following embodiments are first explained.

[0143] 1. Enable the function

[0144] In the embodiment of the present application, when the foldable screen mobile phone has a certain function, turning on the function means turning on the switch of the function so that the foldable screen mobile phone can use the function. After turning on a certain function, the function is said to be in the turned-on state, the turned-on state, or the function is said to be turned on.

[0145] 2. Turn off the function

[0146] In the embodiment of the present application, when the foldable screen mobile phone has a certain function, turning off the function means turning off the switch of the function so that the foldable screen mobile phone cannot use the function. After turning off a function, the function is said to be in the off state, or the function is said to be turned off.

[0147] 3. Enter function

[0148] In the embodiment of the present application, entering a certain function means starting to use the function through user operation or automatic triggering of the foldable screen mobile phone when the function is turned on. Entering a function is also called enabling a function or starting a function.

[0149] 4. Exit function

[0150] In the embodiment of the present application, exiting a certain function means stopping the use of the function through user operation or automatic triggering of the foldable screen mobile phone when the function is turned on.

[0151] In the implementation of this application, the camera application in the foldable screen mobile phone has a rear selfie function. When the rear selfie function is turned on, the user can take selfies through the rear camera, improving the quality and effect of the selfie images. The following describes the relevant process based on the use stage of the rear selfie function and the application scenario.

[0152] 1. Turning the rear selfie function on and off

[0153] 1. Enable the rear selfie function

[0154] For example, FIG8 is a schematic diagram of the interface changes in the process of turning on the rear selfie function provided by an embodiment of the present application. Taking the folding screen mobile phone in the folded state as an example, when the rear selfie function is not turned on, after the camera application is started, the folding screen mobile phone obtains the image through the rear camera, and displays the photo preview interface 908 through the main screen. The photo preview interface 908 includes the image obtained by the rear camera, as shown in FIG8 (a). In other words, when the photo preview interface 908 is in the folded state and the rear selfie function is turned off, the preview interface of the rear non-selfie scene. In addition, as shown in FIG8 (a), when the rear selfie function is turned on, the photo preview interface 908 includes a flip camera control 909 (also called a second control). The flip camera control 909 is used for the user to control the switching between the rear camera and the front camera.

[0155] The photo preview interface 908 also includes a settings control 903. When a user taps on the settings control 903, the foldable phone displays a camera settings interface 904 in response to the user's operation, as shown in FIG8(b). The camera settings interface 904 includes a rear-mounted selfie option 905. When a user taps on the rear-mounted selfie option 905, the foldable phone displays a rear-mounted selfie settings interface 906 in response to the user's operation, as shown in FIG8(c).

[0156] The rear-mounted selfie setting interface 906 includes a rear-mounted selfie function switch control (referred to as the rear-mounted selfie switch) 907. As shown in Figure 8(c), the rear-mounted selfie switch 907 is currently off and grayed out. When the user taps the rear-mounted selfie switch 907, the foldable screen phone responds to the user's action by turning on the rear-mounted selfie function, and the rear-mounted selfie switch 907 is highlighted, as shown in Figure 8(d).

[0157] Afterwards, the user can perform two return operations, exiting the rear selfie settings interface 906 and the camera settings interface 904 in turn. The foldable screen phone displays the photo preview interface 901 (also known as the second photo preview interface), as shown in Figure 8 (e). Photo preview interface 901 is the preview interface for the rear non-selfie scene when the phone is in the folded state and the rear selfie function is turned on. Unlike photo preview interface 908, photo preview interface 901 displays the rear selfie control (also known as the first control) 902. Optionally, photo preview interface 901 can be based on photo preview interface 908, with the flip camera control 909 in photo preview interface 908 replaced by the rear selfie control 902. Optionally, photo preview interface 901 can also be based on photo preview interface 908, with the rear selfie control 902 additionally displayed. In other words, the rear selfie control 902 and the flip camera control 909 can be displayed simultaneously in the interface. The rear selfie control is used to enter the rear selfie function. Optionally, the return operation can be, for example, a side-swipe operation (i.e., sliding inward from the side of the screen), clicking the return button in the three-button navigation bar, or clicking the return control in the interface, etc., which is not limited in this embodiment of the present application. The return operation in the following embodiments is also the same and will not be repeated here.

[0158] It is understandable that the rear selfie function of the foldable screen mobile phone can also be turned on by default when it leaves the factory. After that, the user can turn off the rear selfie function as needed during use.

[0159] 2. Turn off the rear selfie function

[0160] The process of turning off the rear Selfie function is similar to the above-mentioned turning on process. The difference is that the turning on process is to switch the rear Selfie switch 907 from the off state to the on state, while the turning off process is to switch the rear Selfie switch 907 from the on state to the off state. It will not be repeated here.

[0161] It should be noted that the above description uses the folding screen mobile phone in the folded state as an example to explain the process of turning on and off the rear selfie function. When the folding screen mobile phone is in the unfolded state, the rear selfie function can also be turned on or off. The operation process and the interface change process are similar to the above process and will not be repeated. In addition, in this embodiment, the rear selfie setting interface 906 is entered through the camera setting interface 904 to turn on or off the rear selfie function. In other embodiments, the rear selfie setting interface 906 can also be entered by other means. For example, the rear selfie setting interface 906 can be entered through the setting application of the folding screen mobile phone. This application does not impose any limitation on this.

[0162] In this embodiment, the user can independently set the rear selfie function to be on or off as needed to meet the usage requirements of different scenarios, facilitate user operation, and improve user experience.

[0163] 2. Display of rear selfie controls and flip camera controls

[0164] As shown in Figure 9 (a) above, when the rear-facing selfie function is on, the photo preview interface 901 includes a rear-facing selfie control 902. In another embodiment, the photo preview interface 901 may also include a flip camera control 909. When the user clicks the flip camera control 909, the user enters the front-facing selfie scene, and the photo preview interface 1501 for the front-facing selfie scene is displayed (the same interface as shown in Figure 5 (b)). The front-facing selfie scene refers to the scene of taking a selfie using the front camera. For details about the photo preview interface 1501, please refer to Figure 15 (b) in the subsequent embodiments. In other words, in this embodiment, the photo preview interface 901 may include both controls for entering the rear-facing selfie and controls for entering the front-facing selfie. In this way, the user can choose to take a rear-facing selfie or a front-facing selfie according to their needs, which is convenient for the user and improves the user experience.

[0165] In another embodiment, when a foldable phone displays a photo preview interface 901 on the main screen, the user can use a preset gesture to call out a flip camera control 909. For example, FIG9 is a schematic diagram of a process for calling out a flip camera control provided in an embodiment of the present application. As shown in FIG9(a), when the foldable phone is in a folded state and the rear selfie function is turned on, the camera application is started and displays a photo preview interface 1901.

[0166] The photo preview interface 1901 includes a rear selfie control 902, and an arrow mark 1902 is displayed above the rear selfie control 902. Optionally, the user can click the arrow mark 1902 (also called the second operation) or slide up at the rear selfie control 902 (also called the second operation). In response to the user's operation, the folding screen mobile phone displays a capsule 1903 in the area where the original rear selfie control 902 is located, as shown in Figure (b) of Figure 9. Capsule 1903 includes the rear selfie control 902 and the flip camera control 909, and the user can choose to click according to needs.

[0167] If the user does not select the control in capsule 1903 after capsule 1903 is displayed for the preset time, that is, the user does not operate capsule 1903 within the preset time, then capsule 1903 is hidden and the interface is restored to the photo preview interface 1901, as shown in Figure 18 (c).

[0168] In this embodiment, the user can call out the capsule through a preset operation, and choose to click the rear selfie control 902 or the flip camera control 909 in the capsule to control the camera to enter the rear selfie function or the front selfie scene. In this way, on the one hand, the user can choose the rear selfie or the front selfie according to the usage needs, which is convenient for the user to use and improves the user experience; on the other hand, when the user does not perform the preset gesture, the front selfie scene is not displayed in the interface, which facilitates the arrangement of the controls in the interface, prevents the controls in the interface from being too crowded and affecting the user operation, and further improves the user experience.

[0169] 3. Flip wake-up settings

[0170] In an embodiment of the present application, when the rear selfie function is turned on, the camera application of the foldable screen mobile phone may also have a "flip wake-up rear selfie function" (referred to as the flip wake-up function). The flip wake-up function is off by default, and the user can manually turn on the function. After the flip wake-up function is turned on, when the user lifts the phone to face the face and looks at the screen according to the flip wake-up requirements, and then the user flips the phone, the foldable screen phone recognizes the face through the front camera, detects that the user flips the phone through the sensor, and then recognizes the face through the rear camera, triggering the camera application to automatically enter the rear selfie function. The operation of the user flipping the phone according to the above requirements is also called the first operation.

[0171] The setting process of the flip wake-up function is similar to that of the rear selfie function, which is briefly described below with reference to the accompanying drawings.

[0172] 1. Turn on the flip wake-up function

[0173] For example, Figure 10 is a schematic diagram of the interface changes during the setup process of the flip wake-up function provided in an embodiment of the present application. As shown in Figure 10 (a), when the foldable screen mobile phone is in the folded state, after the camera application is started, the user can enter the rear selfie setting interface 906 according to the process shown in Figures (a) to (c) in Figure 8. The specific process is shown in the embodiment shown in Figure 8 and will not be repeated here.

[0174] As shown in Figure 10 (a), the rear selfie switch 907 in the rear selfie setting interface 906 is now in the on state and highlighted. The rear selfie setting interface 906 includes a switch control (referred to as the flip wakeup switch) 1001 for flipping to wake up the rear selfie function. The flip wakeup switch 1001 is in the off state by default and is grayed out. The user clicks the flip wakeup switch 1001, and the foldable screen phone responds to the user's operation, turning on the flip wakeup function, and the flip wakeup switch 1001 is highlighted, as shown in Figure 10 (b).

[0175] Afterwards, the user performs two return operations, and the foldable screen mobile phone exits the rear selfie setting interface 906 and the camera setting interface 904 in succession, and restores the display of the photo preview interface 901, as shown in Figure 10 (c).

[0176] 2. Turn off the flip wake function

[0177] The process of turning off the flip wake-up function is similar to the above-mentioned turning on process. The difference is that the turning off process is to switch the flip wake-up switch 1001 from the on state to the off state, which will not be repeated here.

[0178] In this embodiment, the user can independently set the flip wake-up function to be on or off as needed to meet the user's different usage habits, meet the user's needs in different usage scenarios, facilitate user operation, and improve user experience.

[0179] 4. Enabling the rear selfie function

[0180] When the rear-mounted selfie function is turned on, the user can enter the rear-mounted selfie function through the corresponding operation when using the camera application. After entering the rear-mounted selfie function, the main screen of the folding screen mobile phone goes out, the secondary screen lights up, the folding screen mobile phone obtains the image through the rear camera, and displays the photo preview interface 1106 (also called the first photo preview interface) on the secondary screen. The photo preview interface 1106 includes the image obtained by the rear camera. In other words, the photo preview interface 1106 is the photo preview interface in the rear-mounted selfie scenario, that is, the photo preview interface when using the rear-mounted selfie function. When the folding screen mobile phone displays the photo preview interface 1106, the user can take a selfie through the rear camera after flipping the phone. The image quality and effect obtained by the selfie are better, which improves the user experience. Moreover, when using the rear-mounted selfie function, the user can perform selfie-related operations through the secondary screen, which is convenient to use and further improves the user experience.

[0181] In the embodiment of the present application, multiple ways of entering the rear selfie function are provided, which are described below in combination with the scenarios.

[0182] 1. Start the camera for the first time and enter the rear selfie function

[0183] As mentioned above, the rear-mounted selfie function is enabled by default when the foldable screen mobile phone is shipped from the factory. When a user first launches the camera application of the foldable screen mobile phone, the foldable screen mobile phone launches the photo preview interface 901 by default and displays guidance information in the photo preview interface 901 to guide the user in using the rear-mounted selfie function, making it easier for the user to understand how to use the rear-mounted selfie function and improving the user experience.

[0184] For example, Figure 11 is a schematic diagram of interface changes during the process of entering the rear-mounted selfie function provided by an embodiment of the present application. As shown in Figure 11 (a), when the foldable screen mobile phone is in the folded state, the secondary screen of the foldable screen mobile phone is in the off state, the main screen is in the on state, and the main screen displays the main interface 1101.

[0185] It should be noted that, generally, when the folded phone is in the main screen state, the user will turn the main screen side of the foldable phone toward the user and the secondary screen side (i.e., the side with the rear camera) away from the user. This example is used in the embodiments of the present application to illustrate the situation before and after the user flips the foldable phone.

[0186] The main interface 1101 includes an icon 1102 for the camera application. The user clicks on the icon 1102 for the camera application to trigger the first launch of the camera application. In response to the user's operation, the folding screen mobile phone acquires the image through the rear camera by default, and displays a photo preview interface 1103 (also called a second photo preview interface) through the main screen, as shown in Figure 11 (b). The photo preview interface 1103 is similar to the photo preview interface 901 shown in Figure 8 (a) above, but the difference is that, in this embodiment, the user is launching the camera application of the folding screen mobile phone for the first time, so the photo preview interface 1103 also includes guidance information 1104. Guidance information 1104 is used to guide the user to enter the rear selfie function through the rear selfie control 902.

[0187] Optionally, the guidance information 1104 may be displayed in the form of bubbles, cards, capsules, etc. The guidance information 1104 may include prompt text or prompt images to introduce the rear-mounted selfie function. For example, in Figure 11 (b), the guidance information 1104 may include a prompt image (a selfie image of a person) and prompt text such as "Use the rear-mounted selfie super-sensitive portrait lens to take better portrait effects."

[0188] The user clicks on the rear selfie control 902 (also known as the first operation). In response to the user's operation, the foldable screen mobile phone displays a flip guidance interface (also known as the first flip guidance interface) 1105 through the main screen, as shown in Figure 11 (c). The flip guidance interface 1105 is used to guide the user to flip the foldable screen mobile phone so that the side where the secondary screen is located (i.e., the side where the rear camera is located) faces the user and the side where the main screen is located faces away from the user. Optionally, the flip guidance interface 1105 may include text prompt information 1151, an arrow 1152 indicating the flip direction, and a schematic diagram 1153 of the foldable screen mobile phone. Optionally, the flip guidance interface 1105 may continuously display multiple schematic diagrams 1153 of the foldable screen mobile phone at different angles to present a dynamic picture of the flipped mobile phone, so as to more clearly guide the user to flip the phone and improve the user experience. Optionally, the text prompt information 1151 may be, for example, "Please flip the phone and use the rear selfie."

[0189] Optionally, in an embodiment of the present application, when the flip guide interface is displayed on the main screen or the secondary screen, the touch function of the screen can be hidden (i.e., blocked), that is, the screen does not respond to the user's touch operation. This can prevent the user from accidentally touching the screen and affecting the access to the rear selfie function, thereby improving the user experience.

[0190] After the flip guide interface 1105 is displayed for a preset time (e.g., 3 seconds), the camera application enters the rear selfie function. Specifically, the foldable screen phone turns off the main screen and controls the secondary screen to light up. At the same time, the image is acquired through the rear camera, and the photo preview interface 1106 is displayed on the secondary screen. The photo preview interface 1106 includes the image acquired by the rear camera. After the user flips the foldable screen phone, the side where the secondary screen is located (i.e., the side where the rear camera is located) faces the user, and the side where the main screen is located faces away from the user. In this way, the user's own image (i.e., the selfie image) acquired by the rear camera can be displayed in the photo preview interface 1106, as shown in Figure 11 (d).

[0191] Optionally, in some other embodiments, when the main screen displays the flip guide interface 1105, the secondary screen may light up simultaneously, capture an image through the rear camera, and display a photo preview interface 1106 on the secondary screen. In other words, after the user clicks the rear selfie control, the secondary screen displays the flip guide interface 1105, lights up, and displays the photo preview interface 1106 on the secondary screen.

[0192] Optionally, while the secondary screen displays the flip guide interface 1105, the foldable screen mobile phone can block the touch function of the main screen and the secondary screen. That is, the touch function of the main screen and the secondary screen is blocked within a preset time (for example, 3 seconds) after the user clicks the rear selfie control 902. This can prevent users from accidentally touching the screen and improve the user experience.

[0193] The photo preview interface 1106 includes a photo control 1107. When the user clicks the photo control 1107, the camera application saves the image captured by the rear camera.

[0194] Optionally, the shooting modes supported by the rear-mounted selfie function may include photo mode, video mode, portrait mode, night scene mode, etc. As a possible implementation, after the user enters the rear-mounted selfie function through the above process, the default shooting mode is the same as the shooting mode before entering the rear-mounted selfie function, that is, the shooting mode in the photo preview interface 1106 is the same as the shooting mode in the photo preview interface 1103. This can inherit the user's selection and improve the user experience. Of course, after entering the rear-mounted selfie function, the user can also switch the shooting mode to another mode as needed.

[0195] It is understood that when the user is not using the camera for the first time (second time and each time thereafter), the guidance information can be removed from the photo preview interface to prevent interruption to the user and further improve the user experience. When the user is not using the camera for the first time, the method for entering the rear selfie function and the interface display are the same as the above process and will not be repeated here.

[0196] 2. Flip the phone to wake up the rear selfie function

[0197] As mentioned above, the camera application of the foldable screen mobile phone can have a flip wake-up rear selfie function. When the flip wake-up rear selfie function and the rear selfie function are turned on at the same time (refer to Figure 10), the foldable screen mobile phone can automatically detect the user's operation. If the user's operation meets the flip wake-up requirements, the camera application automatically enters the rear selfie function. In this way, the user does not need to perform operations such as clicking on the rear selfie control in the interface, and can quickly and conveniently enter the rear selfie function, thereby improving the intelligence of the mobile phone and thus improving the user experience. The following is an explanation with reference to the accompanying drawings.

[0198] For example, FIG12 is a schematic diagram of the interface changes in the process of waking up the rear selfie by flipping a mobile phone provided in an embodiment of the present application. As shown in FIG12 (a), when the folding screen mobile phone is in the folded state, the secondary screen of the folding screen mobile phone is in the off state, and the main screen is in the bright state. When the folding screen mobile phone starts the camera application and the rear selfie function is turned on but not entered, the main screen displays the photo preview interface 901. At this time, the side where the main screen of the folding screen mobile phone is facing the user, and the side where the secondary screen is facing away from the user.

[0199] If the user wants to use the rear-mounted selfie function, the user can lift the foldable screen phone according to the flip wake-up instruction, so that the main screen of the foldable screen phone is facing the face and the user looks at the screen. Then the user flips the foldable screen phone so that the side with the secondary screen faces the user and the side with the main screen faces away from the user. During this process, the foldable screen phone recognizes the face through the front camera and detects that the user flips the phone through the sensor. After that, the rear camera recognizes the face and the camera application directly enters the rear-mounted selfie function. The foldable screen phone controls the main screen to turn off, the secondary screen to light up, and displays the photo preview interface 1106 on the secondary screen, as shown in Figure 12 (b).

[0200] When the user wishes to exit the rear-mounted selfie function, the user can reverse the above process, lift the foldable phone so that the secondary screen of the foldable phone is facing the face and the user looks at the screen. Then, the foldable phone is flipped over so that the main screen faces the user and the secondary screen faces away from the user. The foldable phone recognizes the face through the rear camera, detects that the user flips the phone, and recognizes the face through the front camera. The rear-mounted selfie function is directly exited, the secondary screen turns off, the main screen turns on, and the photo preview interface 901 is displayed on the main screen, as shown in Figure 12 (a).

[0201] 3. Enter the rear selfie function through the desktop shortcut menu (also known as the desktop long press menu shut cut)

[0202] In this embodiment, when the rear selfie function is turned on, the user can also directly enter the rear selfie function through the desktop shortcut menu, without the user having to open the photo preview interface 901 or click the rear selfie control in the photo preview interface 901, thereby simplifying the user's operation process of entering the rear selfie function and improving the user experience.

[0203] For example, Figure 13 is a schematic diagram of the interface changes during the process of accessing the rear selfie function through the desktop shortcut menu provided in an embodiment of the present application. When the foldable screen mobile phone is in the folded state, the secondary screen of the foldable screen mobile phone is in the off state, the main screen is in the on state, and the main screen displays the main interface 1101, as shown in Figure 13 (a).

[0204] The main interface 1101 includes a camera application icon 1102. When the user long-presses the camera application icon 1102, the foldable screen phone responds to the user's operation by displaying a mask in the interface and a shortcut menu (also called a first service card) 1301 for the camera application, as shown in Figure 13 (b).

[0205] The shortcut menu 1301 includes a selfie option 1302. When the rear selfie function is turned on, the user clicks the selfie option 1302, the foldable screen phone starts the camera application, and displays the flip guide interface 1105 through the main screen, as shown in Figure 13 (c).

[0206] After flipping the navigation interface 1105 and displaying it for a preset duration, the camera app enters the rear-facing selfie function. Specifically, the foldable phone turns off the main screen and lights up the secondary screen. Simultaneously, the rear camera captures an image, and the secondary screen displays a photo preview interface 1106, which includes the image captured by the rear camera, as shown in Figure 13 (d).

[0207] It should be noted that when the user clicks on the selfie option 1302, if the rear selfie function is turned off, the foldable screen mobile phone starts the camera application, acquires an image through the front camera, and displays the photo preview interface 1501 (also called the second photo preview interface) through the main screen. The photo preview interface 1501 displays the image acquired by the front camera. The photo preview interface 1501 is a preview interface for the front selfie scenario. For details about the photo preview interface 1501, please refer to the interface 1501 in Figure 15 of the subsequent embodiments.

[0208] For example, Figure 14 is a schematic diagram of the interface changes in another example of the process of entering the rear selfie function through the desktop shortcut menu provided by an embodiment of the present application. Continuing from Figure 13 (b), as shown in Figure 14 (a), when the foldable screen mobile phone displays the shortcut menu 1301 of the camera application, the user can also long press and drag the selfie option 1302 to a certain position in the main interface 1101. After the user raises his hand, the desktop shortcut icon (referred to as the selfie shortcut icon, also called the selfie icon) 1401 of the selfie function is displayed at the position where the hand is raised, as shown in Figure 14 (b).

[0209] With the rear-mounted selfie function enabled, the user taps selfie shortcut icon 1401. The foldable phone responds to the user's action by launching the camera app and displaying a flip guide interface 1105 on the home screen, as shown in Figure 14(c). After displaying flip guide interface 1105 for a preset duration, the camera app enters the rear-mounted selfie function and displays a photo preview interface 1106, as shown in Figure 14(d).

[0210] Similarly, when the user clicks the selfie shortcut icon 1401, if the rear selfie function is turned off, the foldable screen mobile phone starts the camera application, obtains the image through the front camera, and displays the photo preview interface 1501 through the main screen. The photo preview interface 1501 includes the image obtained through the front camera.

[0211] 4. Enter the rear selfie function from the front selfie scene

[0212] When the foldable phone is folded and the rear-facing selfie function is off, the camera app can enter the front-facing selfie scene. In the front-facing selfie scene, the user can turn on the rear-facing selfie function again. After the rear-facing selfie function is turned on, the foldable phone directly guides the user to flip the phone, after which the camera app automatically enters the rear-facing selfie function without the user having to return to the photo preview interface or click the rear-facing selfie control, improving user convenience and further enhancing the user experience.

[0213] Optionally, when the rear selfie function is turned off, the user can enter the front selfie scene by clicking the selfie option 1302 shown in Figure 13 above, or enter the front selfie scene by clicking the selfie shortcut icon 1401 shown in Figure 14 above.

[0214] Optionally, the user can also enter the front selfie scene by flipping the camera control 909 in the photo preview interface 908. The following describes the process of entering the front selfie scene and entering the rear selfie function from the front selfie scene in conjunction with the accompanying drawings.

[0215] Exemplarily, Figures 15 and 16 are schematic diagrams of interface changes in the process of entering the rear selfie function from the front selfie scene provided in an embodiment of the present application, wherein Figure (a) in Figure 16 follows Figure (d) in Figure 15.

[0216] As shown in Figure 15(a), the foldable phone is in the folded state, the secondary screen of the foldable phone is off, and the main screen is on. When the rear selfie function is turned off, the camera application of the foldable phone is activated, and the main screen displays a photo preview interface 908, which includes an image captured by the rear camera.

[0217] The photo preview interface 908 also includes a flip camera control 909. When the user clicks the flip camera control 909, the foldable screen phone responds to the user's operation by switching the rear camera to the front camera, capturing an image through the front camera, and displaying the photo preview interface 1501 on the main screen, as shown in Figure 15 (b).

[0218] The photo preview interface 1501 includes a settings control 903. A user taps on the settings control 903. In response to the user's action, the foldable phone displays a camera settings interface 904, as shown in FIG15(c). The camera settings interface 904 includes a rear-mounted selfie option 905. A user taps on the rear-mounted selfie option 905. In response to the user's action, the foldable phone displays a rear-mounted selfie settings interface 906, as shown in FIG15(d).

[0219] The rear selfie setting interface 906 includes a rear selfie switch 907. Rear selfie switch 907 is currently off and grayed out. When a user taps rear selfie switch 907, the foldable phone responds by turning on the rear selfie function, with rear selfie switch 907 highlighted, as shown in Figure 16 (a).

[0220] Afterwards, the user performs a return operation. In response to the user's operation, the foldable screen phone exits the rear selfie settings interface 906 and displays the camera settings interface 904 on the main screen, as shown in Figure 16 (b). Then, the user performs another return operation. In response to the user's operation, the foldable screen phone exits the camera settings interface 904 and displays the flip guidance interface 1105 on the main screen, as shown in Figure 16 (c).

[0221] After the flip guide interface 1105 is displayed for a preset time, the camera application enters the rear selfie function. The folding screen mobile phone controls the main screen to turn off and the secondary screen to light up. At the same time, the image is obtained through the rear camera, and the photo preview interface 1106 is displayed through the secondary screen. The photo preview interface 1106 includes the image obtained by the rear camera, as shown in Figure (d) in Figure 16.

[0222] 5. After entering the rear selfie function, exit the camera application and go to the background

[0223] After entering the rear-camera selfie function using the methods 1, 3, and 4 in "III. Entering the Rear-Camera Selfie Function" above, if the user exits the camera app and moves it to the background, the foldable phone can retain the memory of the camera app's operation for a preset duration (e.g., 15 minutes). That is, when the user re-activates the camera app within the preset duration, the rear-camera selfie function continues to operate. This eliminates the need for users to repeatedly access the rear-camera selfie function, simplifying operations and improving the user experience.

[0224] For example, FIG17 is a schematic diagram of the interface changes of exiting the camera application during the process of entering the rear-mounted selfie function provided by an embodiment of the present application. As shown in FIG17 (a), the current camera application has entered the rear-mounted selfie function, and the photo preview interface 1106 is displayed on the secondary screen. Afterwards, the user performs the operation of exiting the camera to the background (also called the fourth operation). Among them, the operation of exiting the camera to the background can be, for example: clicking the home button in the three-button navigation bar; after the user performs this operation, the foldable screen mobile phone exits the camera application to the background and displays the main interface (also called the desktop, main page, etc.). The operation of exiting the camera to the background can also be: swiping up from the bottom of the screen to enter the multitasking interface, and the user clicks on the interface thumbnail of other tasks (applications) in the multitasking interface; after the user performs this operation, the foldable screen mobile phone exits the camera application to the background and displays the interface of other applications. The embodiment of the present application does not impose any restrictions on the operation of exiting the camera to the background.

[0225] Taking the example of a user clicking the home button in the three-button navigation bar, in response to the user's operation, the foldable screen mobile phone controls the secondary screen to turn off and controls the main screen to light up, and displays the main interface 1101 through the main screen, as shown in Figure (b) in Figure 17.

[0226] After performing other operations on the main screen, the user taps the camera app icon 1102 on the main interface 1101 again within a preset time (e.g., 15 minutes). In response to the user's operation, the foldable phone launches the camera app and directly enters the rear-facing selfie function, displaying a flip guide interface 1105, as shown in Figure 17 (c). After the flip guide interface 1105 is displayed for the preset time, the camera app enters the rear-facing selfie function, the foldable phone controls the main screen to turn off, the secondary screen to light up, and the photo preview interface 1106 is displayed on the secondary screen, as shown in Figure 17 (d).

[0227] 6. Unfolding the phone while using the rear selfie function

[0228] In this embodiment, during the use of the rear-mounted selfie function, if the user unfolds the foldable screen mobile phone, the camera application exits the rear-mounted selfie function and enters the rear-mounted non-selfie scene in the unfolded state. The rear-mounted non-selfie scene in the unfolded state means that the foldable screen mobile phone obtains an image through the rear camera, and displays the photo preview interface 1801 (also called the fifth photo preview interface) through the main screen and the sub-screen. The photo preview interface 1801 includes the image obtained by the rear camera. In other words, the photo preview interface 1801 is a photo preview interface for the unfolded rear-mounted non-selfie scene. The user unfolds the foldable screen mobile phone to the unfolded state, which means that the user no longer needs the rear-mounted selfie function. Therefore, directly entering the unfolded rear-mounted shooting scene is likely to meet the user's usage needs and improve the user experience.

[0229] For example, Figure 18 is a schematic diagram of the interface changes of an unfolded mobile phone during the use of the rear-mounted selfie function provided in an embodiment of the present application. As shown in Figure 18 (a), the user is using the rear-mounted selfie function, and the foldable screen mobile phone displays a photo preview interface 1106 on the secondary screen. The photo preview interface 1106 includes an image captured by the rear camera. At this time, the side of the foldable screen mobile phone where the secondary screen is located (i.e., the side where the rear camera is located) is facing the user, and the side where the main screen is located is facing away from the user.

[0230] The user unfolds the foldable phone, switching it to the unfolded state. In this state, the main screen and secondary screen of the foldable phone face the user, while the first back shell, the second back shell, and the rear camera face away from the user. In response to the user's operation, the foldable phone continues to capture images through the rear camera. Simultaneously, the secondary screen lights up, and the main screen and secondary screen jointly display a photo preview interface 1801, which includes the image captured by the rear camera, as shown in Figure 18 (b).

[0231] Optionally, when the user unfolds the foldable screen phone through the above process and the foldable screen phone enters the unfolded state and the rear camera shooting scene, the default shooting mode is the same as the shooting mode when using the rear selfie function, that is, the shooting mode in the photo preview interface 1801 is the same as the shooting mode in the photo preview interface 1106. This can inherit the user's selection and improve the user experience.

[0232] 7. Viewing images while using the rear selfie function

[0233] In this embodiment, when a user uses the rear-mounted selfie function, they can view the captured image through the image thumbnail in the photo preview interface 1106. The image can be displayed on the secondary screen and supports functions such as favorites, deletion, and zoom display. This allows the user to view the image at any time without exiting the rear-mounted selfie function, which is convenient for the user and improves the user experience.

[0234] Furthermore, when the user unfolds the foldable phone while viewing an image, the image is displayed across both the main and secondary screens, supporting functions such as sharing, saving, editing, and deleting. This means that while viewing an image on the secondary screen, the user can unfold the foldable phone at any time to display the image simultaneously on both the main and secondary screens, enabling large-scale image previews for ease of use and an improved user experience.

[0235] The following is a description with reference to the accompanying drawings.

[0236] For example, Figure 19 is a schematic diagram illustrating changes in the image viewing interface during use of the rear-mounted selfie function, as provided in an embodiment of the present application. As shown in Figure 19 (a), a user is using the rear-mounted selfie function, and the foldable screen phone displays a photo preview interface 1106 on the secondary screen. The photo preview interface 1106 includes a thumbnail (also known as a third control) 2101 of the image captured by the user.

[0237] The user clicks thumbnail 2101, and the foldable screen phone responds to the user's operation by displaying an image preview interface 2102 (also known as the first interface) on the secondary screen. Image preview interface 2102 includes the image corresponding to thumbnail 2101, as shown in Figure 19 (b). In addition, image preview interface 2102 includes a favorites control 2121, a delete control 2126, a switch home screen control (also known as the fourth control) 2123, and a return control 2124. The user clicks the favorites control 2121, and the foldable screen phone adds the image to the favorites. The user clicks the delete control 2126, and the foldable screen phone deletes the image. The user clicks the switch home screen control 2123, and the camera app exits the rear-mounted selfie function and enters the rear-mounted non-selfie scene in the folded state. The foldable screen phone displays the photo preview interface 901. The user clicks the return control 2124, and the foldable screen phone exits the current image preview interface 2102 and resumes displaying the photo preview interface 1106.

[0238] In addition, if the user performs a two-finger zoom operation on the image displayed in the image preview interface 2102, the foldable screen mobile phone responds to the user's operation and reduces or enlarges the image. Taking the user performing a two-finger zoom operation as an example, the foldable screen mobile phone may display the enlarged image on the secondary screen as shown in Figure 19 (c). The two-finger zoom operation may be, for example, a two-finger pinch operation.

[0239] In another embodiment, when the foldable screen mobile phone displays the interface shown in Figure 19 (b), if the user unfolds the foldable screen to the unfolded state, the main screen and the sub-screen simultaneously display the image preview interface 2103 (also called the second interface), as shown in Figure 19 (d).

[0240] 8. Exit the rear selfie function

[0241] While using the rear-mounted selfie function, the user can exit the rear-mounted selfie function by using the switch home screen control or the flip camera control in the photo preview interface 1106, or by using the switch home screen control in the photo preview interface. After exiting the rear-mounted selfie function, the camera application enters the rear-mounted non-selfie mode in the folded state. The foldable screen phone turns off the secondary screen and displays the photo preview interface 901 on the main screen. In other words, the user can exit the rear-mounted selfie function at any time while using the function, which facilitates user operation and usage and improves the user experience.

[0242] For example, Figure 20 is a schematic diagram of the interface changes for exiting the rear-mounted selfie function provided in an embodiment of the present application. As shown in Figure 20 (a), the user is using the rear-mounted selfie function, and the foldable screen phone displays a photo preview interface 1106 through the secondary screen. The photo preview interface 1106 includes a switch main screen control 2123 and a flip camera control 909. At this time, the side of the foldable screen phone where the secondary screen is located (i.e., the side where the rear camera is located) is facing the user, and the side where the main screen is located is facing away from the user.

[0243] The user clicks on the switch main screen control 2123, or clicks on the flip camera control 909. In response to the user's operation, the foldable screen mobile phone displays a flip guide interface 2201 (also called a second flip guide interface) through the secondary screen, as shown in Figure 20 (b). The flip guide interface 2201 is used to guide the user to flip the foldable screen mobile phone so that the side where the main screen is located faces the user and the side where the secondary screen is located (i.e., the side where the rear camera is located) faces away from the user. Optionally, the flip guide interface 2201 may include text prompt information 2211, an arrow 2212 indicating the flip direction, and a foldable screen mobile phone schematic diagram 2213. Optionally, multiple foldable screen mobile phone schematic diagrams at different angles can be displayed continuously to present a dynamic picture of flipping the mobile phone in the flip guide interface 2201, so as to more clearly guide the user to flip the mobile phone and improve the user experience. Optionally, in this interface, the text prompt information 2211 can be, for example, "The rear selfie has exited, please flip the phone."

[0244] After the flip guide interface 2201 is displayed for a preset period of time, the camera application exits the rear selfie function. Specifically, the foldable screen phone turns off the secondary screen and controls the main screen to light up. At the same time, the rear camera captures images and displays a photo preview interface 901 on the main screen. The photo preview interface 901 includes the image captured by the rear camera. After the user flips the phone, the photo preview interface 901 can display images of people or objects around the user captured by the rear camera, as shown in Figure 20 (c).

[0245] In other embodiments, the photo preview interface 1106 shown in FIG. 20 (a) may further include a rear selfie exit control 2125 (also referred to as a fourth control), and the user may exit the rear selfie function by clicking the rear selfie exit control 2125. After the user clicks the rear selfie exit control 2125, the interface changes as shown in FIG. 20 (b) and (c), and will not be further described.

[0246] In the above embodiments, the user is able to independently control the turning on and off of the rear selfie function as an example. In other embodiments, the rear selfie function of the electronic device may also be continuously turned on, that is, the rear selfie function is continuously available. In this case, the user does not need to control the turning on and off of the rear selfie function, but the user can set the default selfie mode to rear selfie or rear non-selfie, thereby selecting the default control displayed in the photo preview interface to be the rear selfie control or the flip camera control. In this way, the display of the interface is more in line with the user's habitual choice, improving the user experience. Moreover, after displaying one of the two default controls, the user can call out the other, conveniently and quickly realizing the choice of two selfie modes. The following is further explained with reference to the accompanying drawings.

[0247] For example, FIG21 is a schematic diagram of an interface change for setting the default selfie mode provided in an embodiment of the present application. As shown in FIG21 (a), continuing to take the foldable screen mobile phone as an example, the foldable screen mobile phone is in the folded state, the main screen is in the off state, and the secondary screen is in the bright state. After the camera application is started, it defaults to the rear non-selfie scene. The foldable screen mobile phone captures the image through the rear camera and displays the photo preview interface 1901 on the main screen. The photo preview interface 1901 includes the image captured by the rear camera. Optionally, the default selfie mode of the foldable screen mobile phone can be the rear selfie. Therefore, the photo preview interface 1901 includes a rear selfie control 902, and an arrow mark 1902 is displayed above the rear selfie control 902. The user can call out capsule 1903 by clicking the arrow mark 1902 or swiping up. The rear selfie control 902 and the flip camera control 909 in capsule 1903 are specifically shown in the embodiment shown in FIG9.

[0248] The photo preview interface 1901 also includes a setting control 903. The user clicks on the setting control 903 (also called the third operation). The foldable screen mobile phone responds to the user's operation and displays the camera setting interface 2301, as shown in Figure (b) of Figure 21. The camera setting interface 2301 includes a setting option for the selfie mode (referred to as the selfie mode option) 2302. The selfie mode currently displayed in this option is the rear selfie. In addition, the camera setting interface 2301 may also include a flip wake-up rear selfie option 2305. The user can enter the setting interface of the flip wake-up function by clicking on this option 2305. Optionally, the setting interface of the flip wake-up function can be similar to Figure (a) in Figure 10 above. The difference is that the setting interface of the flip wake-up function in this embodiment does not include a rear selfie switch.

[0249] The user clicks on the selfie mode option 2302, and the foldable screen mobile phone responds to the user's operation and displays a selfie mode selection pop-up window 2303, as shown in Figure 21 (c).

[0250] The selfie mode selection pop-up window 2303 (also referred to as the first pop-up window) includes a rear-facing selfie option 2313 and a front-facing selfie option 2323. Rear-facing selfie option 2313 is currently selected. The user can tap front-facing selfie option 2323 to select the front-facing camera as the default for selfies. In response to the user's action, the foldable phone displays interface 2304 (also referred to as the third photo preview interface), as shown in Figure 21 (d).

[0251] Afterwards, the user closes the selfie mode selection pop-up window 2303 and exits the camera settings interface 2301. The foldable screen phone responds to the user's operation by displaying a photo preview interface 2304 on the main screen, as shown in Figure 21 (e). The photo preview interface includes an image captured by the rear camera and includes a flip camera control 909. An arrow mark 1902 may be displayed above the flip camera control 909.

[0252] Optionally, the user can click on the arrow mark 1902 or swipe up on the flip camera control 909. In response to the user's operation, the foldable screen phone displays a capsule 2306 in the area where the flip camera control 909 was originally located, as shown in Figure 21 (f). Similar to Figure 9 (b), capsule 2306 includes the rear selfie control 902 and the flip camera control 909. Unlike capsule 1903, the display positions of the rear selfie control 902 and the flip camera control 909 in the capsule are different. In capsule 1903, the rear selfie control 902 is displayed at the bottom and the flip camera control 909 is displayed at the top. In this embodiment, in capsule 2306, the flip camera control 909 is displayed at the bottom and the rear selfie control 902 is displayed at the top. That is to say, when the rear selfie control 902 is displayed by default in the photo preview interface, the user can swipe up to add the flip camera control 909 to the interface; when the flip camera control 909 is displayed by default in the photo preview interface, the user can swipe up to add the rear selfie control 902 to the interface.

[0253] If the user does not select a control in capsule 1903 after capsule 1903 is displayed for a preset time, that is, the user does not operate capsule 1903 within the preset time, capsule 1903 is hidden and the interface returns to the photo preview interface 2304.

[0254] If the rear-facing selfie function is still available, when the camera app is in the front-facing selfie scene, the photo preview interface can also include a rear-facing selfie control to facilitate users to directly click the rear-facing selfie control to enter the rear-facing selfie function.

[0255] For example, Figure 22 is another example of the interface changes during the process of entering the rear-facing selfie function from the front-facing selfie scene provided by an embodiment of the present application. As shown in Figure 22 (a), the foldable screen mobile phone is in the folded state, the main screen is in the bright state, the secondary screen is in the off state, the camera application is activated, and the main screen displays the photo preview interface 2304. The photo preview interface 2304 includes an image captured by the rear camera.

[0256] The photo preview interface 2304 includes a flip camera control 909. The user clicks on the flip camera control 909. In response to the user's operation, the front selfie scene is entered and the photo preview interface 2401 (also called the fourth photo preview interface) is displayed. The photo preview interface 2401 includes the image obtained by the front camera, as shown in Figure (b) of Figure 22. In addition, the photo preview interface 2401 also includes a rear selfie control 2402 (also called the first control). Optionally, when the folding screen mobile phone detects that it is currently in a dark environment, a prompt message can be displayed in the rear selfie space 2402 to prompt the user to use the rear selfie function. Optionally, the prompt message can be displayed in the form of a bubble or the like for a preset duration. The content of the prompt message can be, for example, "Use the rear super-sensitive lens to take selfies for better results".

[0257] The user clicks on the rear selfie control 2402 (also called the first operation). In response to the user's operation, the foldable screen mobile phone displays the flip guide interface 1105 through the main screen, as shown in Figure (c) in Figure 22.

[0258] After flipping the navigation interface 1105 and displaying it for a preset time, the camera app enters the rear selfie function. Specifically, the foldable phone turns off the main screen and lights up the secondary screen. Simultaneously, the rear camera captures an image, and the secondary screen displays a photo preview interface 1106, which includes the image captured by the rear camera, as shown in Figure 22 (d).

[0259] In this embodiment, in the front-facing selfie scenario, the interface includes a rear-facing selfie control, and the user can directly click the control to enter the rear-facing selfie function, which facilitates user operation and improves user experience.

[0260] In another embodiment, when the rear-facing selfie function is continuously available, the foldable phone is in a folded state, the main screen is in a bright state, the secondary screen is in a dark state, the camera application is activated, and the main screen displays the photo preview interface 2304 shown in Figure 22 (a), the user can click the settings control in the photo preview interface 2304 to enter the interface shown in Figure 21 (b). Thereafter, the user sets the default selfie mode to the front-facing selfie according to the operations described in Figures 21 (b), (c), and (d). Thereafter, the user closes the selection pop-up window 2303 and exits the camera settings interface 2301. The foldable phone displays the flip guide interface 1105 on the main screen, as shown in Figure 22 (c). After the flip guide interface 1105 displays for a preset time, the camera application enters the rear-facing selfie function. Specifically, the foldable screen mobile phone turns off the main screen and controls the secondary screen to light up. At the same time, the image is obtained through the rear camera, and the photo preview interface 1106 is displayed through the secondary screen. The photo preview interface 1106 includes the image obtained by the rear camera, as shown in Figure (d) in Figure 22.

[0261] When the rear-camera selfie function continues to be available, when the user enters the rear-camera selfie function through the desktop shortcut menu in the manner of Figure 13 or Figure 14, in response to the user clicking the selfie option 1302 or the selfie shortcut icon 1401, the camera application is started and enters the corresponding photo preview interface according to the default selfie mode set by the user.

[0262] It can be understood that when the rear selfie function continues to be available, the method of entering the rear selfie function through other scenes is the same or similar to the case where the user can set the rear selfie function to be turned on and off, and will not be repeated here.

[0263] The above-mentioned method provided by the present application is described by taking an external folding screen mobile phone as an example. In some other embodiments, the above-mentioned method can also be applied to an internal folding screen mobile phone. The structure of the internal folding screen mobile phone is different from that of the external folding screen mobile phone. For example, Figure 23 is a structural schematic diagram of an example of a folding screen mobile phone 20 provided in an embodiment of the present application, and the folding screen mobile phone 20 is an internal folding screen mobile phone. As shown in Figure 23, the folding screen mobile phone 20 includes a first structural member 21, a second structural member 22, and a connecting assembly 23 connecting the first structural member 21 and the second structural member 22 (located at the position shown by the dotted line in Figure (a) of Figure 23), and the first structural member 21 and the second structural member 22 are flipped and folded through the connecting assembly 23.

[0264] The first structural member 21 may include a first inner display screen 211 and a back housing 212. A first front camera 2111 is disposed on the first inner display screen 211. The first back housing 212 is disposed on the back of the first inner display screen 211. A rear camera 2122 may be disposed on the back housing 212.

[0265] The second structural member 12 may include a second inner display screen 221 and an outer display screen 222. The second inner display screen 221 is disposed opposite to the outer display screen 222. The outer display screen 222 may be provided with a second front camera 2221.

[0266] During use, the angle between the first structural member 21 and the second structural member 22 is adjusted by the connecting assembly 23, thereby realizing various configurations of the foldable screen phone 20. It is understood that the second inner display 221 and the first inner display 211 can actually be a single, integrally formed flexible display (i.e., a foldable screen, also known as the inner display of an inner foldable screen phone). When the foldable screen phone 20 is folded via the connecting assembly 23, the connecting assembly 23 divides the screen into two parts: the second inner display 221 and the first inner display 211.

[0267] As shown in Figure (a) in Figure 23, when the angle between the first structural member 21 and the second structural member 22 is approximately 180°, the foldable screen mobile phone 20 is in the unfolded state. At this time, the surface of the first back shell 212 and the surface of the outer display screen 222 are approximately in the same plane. At this time, the outer display screen 222 and the rear camera 2122 are on the same side. The surfaces of the first inner display screen 211 and the second inner display screen 221 are approximately in the same plane. In the unfolded state, the light emitting direction of the outer display screen 222 is opposite to the light incoming direction of the rear camera 2122. In the unfolded state, the outer display screen 222 is in the off-screen state, and the foldable screen mobile phone 20 displays the content to be displayed simultaneously through the first inner display screen 211 and the second inner display screen 221. It should be noted that in the off-screen state, the outer display screen 222 cannot receive user touch operations.

[0268] When the foldable screen mobile phone 20 is in the unfolded state as shown in Figure 23 (a), and the first inner display screen 211 and the second inner display screen 221 are both lit, the user can gradually fold the foldable screen mobile phone 20 inward (in the direction indicated by the arrow in Figure 23 (a)) to make the foldable screen mobile phone 20 enter the stand state, as shown in Figure 23 (b).

[0269] When the foldable phone 20 is in the stand position, if the angle between the first structural member 21 and the second structural member 22 is greater than 45°, both the first inner display 211 and the second inner display 221 remain illuminated. When the angle between the first structural member 21 and the second structural member 22 gradually decreases to approximately 45°, the first inner display 211 and the second inner display 221 turn off, and the outer display 222 turns on, displaying the desired content. During the subsequent folding process, only the outer display 222 remains illuminated until the angle between the first structural member 21 and the second structural member 22 reaches approximately 0°, resulting in the folded position shown in FIG. 23 (c).

[0270] As shown in Figure 23(c), when the foldable phone 20 is in the folded state, the first inner display 211 and the second inner display 221 are positioned opposite each other and folded inward, while the outer display 222 is positioned outward. In the folded state, the light emitting direction of the outer display 222 is the same as the light entering direction of the rear camera.

[0271] When the inward-folding screen mobile phone implements the functions described in the above embodiments, unlike the outward-folding screen mobile phone, the inward-folding screen, when in the unfolded state, displays the interface of the main screen of the above-mentioned outward-folding screen mobile phone in the folded state through the first inner display and the second inner display. When the camera application enters the rear-mounted selfie function, the first inner display and the second inner display go off, and the outer display lights up, and the photo preview interface under the rear-mounted selfie function is displayed on the outer display. In addition, in the above embodiments, the interface change triggered by unfolding the outward-folding screen mobile phone to the unfolded state can be triggered by folding the inward-folding screen mobile phone to the folded state.

[0272] For example, Figure 24 is a schematic diagram of the interface changes when entering the rear selfie function based on an inward-folding screen mobile phone provided in an embodiment of the present application. As shown in Figure 24 (a), when the folding screen (inward-folding screen) mobile phone is in the unfolded state, the first inner display and the second inner display of the folding screen mobile phone are both in the bright screen state, the outer display is in the off state, and the first inner display and the second inner display display display a photo preview interface 2205. The photo preview interface 2205 includes the rear selfie control 902.

[0273] The user taps rear-mounted selfie control 2202. In response to the user's action, the foldable phone displays a flip guide interface 2203 via both the first and second inner displays, as shown in FIG24(b). The content of flip guide interface 2203 can be similar to that of flip guide interface 1105, except that the structure of foldable phone schematic 2213 is different.

[0274] After the flip guide interface 2203 is displayed for a preset time (for example, 3 seconds), the camera application enters the rear selfie function. Specifically, the first inner display screen and the second inner display screen of the folding screen mobile phone are turned off, and the outer display screen is controlled to light up. At the same time, the image is obtained through the rear camera, and the photo preview interface 2204 is displayed through the outer display screen. The photo preview interface 2204 includes the image obtained by the rear camera. After the user flips the folding screen mobile phone, the side where the outer display screen is located (that is, the side where the rear camera is located) faces the user, and the side where the first inner display screen and the second inner display screen are located faces away from the user. In this way, the user's own image (that is, the selfie image) obtained by the rear camera can be displayed in the photo preview interface 2204, as shown in Figure (c) of Figure 24.
