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, a front camera, and a rear camera, the foldable screen including a first screen and a second screen, the front camera and the first screen being on the same side, and the rear camera being arranged opposite to the first screen, when the electronic device is in an unfolded state, the first screen and the second screen are on the same side, and when the electronic device is in a folded state, the second screen and the rear camera are on the same side, 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 photo preview interface is displayed through the first screen, and the first photo preview interface includes a first control and a second control, wherein the second control is used to control switching between the front camera and the rear camera; a first operation performed by the user on the first control 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 second photo preview interface is displayed through the second screen, and the second 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 control is the rear-mounted selfie control, and the second control is the flip camera control. Optionally, the layout of the first and second controls (i.e., the selfie entry method) can be tiled or sliding. If the layout of the first and second controls is sliding, the first photo preview interface can be an interface that is called up by the user sliding. If the first and second controls can be tiled, the first photo preview interface is an interface that can be directly displayed without user operation.

[0011] Optionally, the first photo preview interface may include images captured by the rear camera or the front camera. The second photo preview interface is also the photo preview interface for the rear selfie scene. In other words, the rear selfie scene can be entered through the rear non-selfie scene in the folded state, and the rear selfie scene can also be entered through the front selfie scene in the folded state.

[0012] Optionally, the first operation may be an operation of clicking a first control in the first photo preview interface.

[0013] The first aspect provides a photographing method that displays a first photographing preview interface when the electronic device is in a folded state, the first screen is in a light-on state, and the second screen is in a dark-off state. The first photographing preview interface includes a first control. The user can trigger the rear-mounted selfie function by acting on the first control. That is, the first screen of the electronic device is dark, the second screen is lighted, and the second photographing preview interface in the rear-mounted selfie scenario is displayed on 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 user's side (i.e., selfies) and view the first photographing preview interface on the second screen, making it convenient for the user to take selfies. Moreover, the second photographing preview interface displays the image captured by the rear camera, that is, in the rear-mounted selfie scenario, the image is acquired through the rear camera. The specifications and hardware configuration of the rear camera are high, the image quality captured is high, the shooting effect is good, and the user experience can be improved. On the other hand, the first photo preview interface includes both the first control and the second control, which allows users to choose to click the first control to enter the rear selfie function or click the second control to enter the front selfie scene according to their needs, thereby meeting the different needs of users in different scenarios and improving user experience.

[0014] In one possible implementation, displaying a first photo preview interface through the first screen includes: displaying a third photo preview interface through the first screen, the third photo preview interface including a second control; receiving a second operation performed by the user on the second control in the third photo preview interface; and displaying the first photo preview interface through the first screen in response to the second operation.

[0015] The third photo preview interface does not include the first control.

[0016] Optionally, the second operation may be, for example, a sliding operation on the second control in the third photo preview interface.

[0017] That is, in this implementation, the layout of the first and second controls is a sliding layout. In the third photo preview interface, the second control is visible and the first control is hidden. The user performs the second operation to call out the first control and display the first photo preview interface.

[0018] Optionally, the third photo preview interface may include images captured by the rear camera or the front camera. In other words, the third photo preview interface may be a preview interface for rear-facing non-selfie scenes in a folded state with a sliding selfie entry, or a preview interface for front-facing selfie scenes in a folded state with a sliding selfie entry.

[0019] In this implementation, on the one hand, the user can call out the first control through the second operation, and then can choose to click the first control or the second control according to usage needs, which is convenient for user use and improves user experience; on the other hand, the second control is a control that the user is more familiar with. When the user does not perform the second operation, the first control is not displayed in the third photo preview interface, and only the second control is displayed. This not only conforms to user usage habits, but also has fewer controls, which facilitates the arrangement of controls in the interface, prevents affecting other controls in the user operation interface, and further improves user experience.

[0020] In a possible implementation, the third photo preview interface further includes an operation guide mark, and the second operation is an operation of acting on the second control and sliding in the direction of the operation guide mark.

[0021] The operation guide mark can be, for example, a double arrow. The operation guide mark can guide the user to perform the second operation, so as to facilitate the user to understand how to use the control and improve the user experience.

[0022] In one possible implementation, the operation guidance mark is displayed above the second control, and the second operation is a swipe-up operation.

[0023] In this implementation, the second operation is a swipe-up operation. When the interface layout space is limited, the swipe-up operation can simply and conveniently call out the second control, which is convenient for user operation and improves the user experience.

[0024] In one possible implementation, the third photo preview interface also includes a camera setting control, and the method also includes: in response to a third operation performed by the user on the camera setting control, displaying the camera setting interface through the first screen, the camera setting interface including a first option, the first option being used to set the layout mode of the first control and the second control in the photo preview interface to the first mode or the second mode, and the current layout mode is the first mode; in response to the user switching the layout mode to the second mode through the first option and exiting the camera setting interface, displaying a fourth photo preview interface through the first screen, the fourth photo preview interface including the first control and the second control displayed in a tiled manner.

[0025] The first option is the selfie entry method option. The first method is the sliding method, and the second method is the flat method.

[0026] The fourth photo preview interface, that is, the selfie entry mode in the folded state is a flat photo preview interface. The fourth photo preview interface may include images obtained by the rear camera or images obtained by the front camera.

[0027] Optionally, the third operation may be, for example, an operation of clicking a camera setting control.

[0028] In this implementation, users can independently switch the selfie entry method through the camera setting controls as needed, meeting the usage needs of different users, facilitating user operation, and improving user experience.

[0029] In one possible implementation, in response to the user switching the layout mode to the second mode through the first option and exiting the camera settings interface, the fourth photo preview interface is displayed through the first screen, including: in response to the user's fourth operation on the first option, a first pop-up window is displayed, the first pop-up window includes the second option corresponding to the first mode and the third option corresponding to the second mode, the second option is in a selected state, and the third option is in an unselected state; in response to the user's fifth operation on the third option, the second option is displayed as an unselected state, and the third option is displayed as a selected state; in response to the user closing the first pop-up window and exiting the camera settings interface, the fourth photo preview interface is displayed through the first screen.

[0030] The second option is the sliding option, and the third option is the tiled option.

[0031] The fourth operation may be, for example, clicking on the first option. The fifth operation may be, for example, clicking on the third option. The first pop-up window is also a pop-up window for setting the selfie entry method.

[0032] In this implementation, the user can clearly know the currently selected layout method through the change of the option status, thereby improving the user experience.

[0033] In one possible implementation, a first photo preview interface is displayed through the first screen, including: in response to the user launching the camera application for the first time in the folded state, the first photo preview interface is displayed, the first photo preview interface also including an image obtained through the rear camera and first guidance information, the first guidance information is used to guide the user to take a selfie through the rear camera (that is, guide the user to use the rear selfie function).

[0034] In this implementation, when a user starts the camera application for the first time in the folded state, the electronic device displays a first guidance message to guide the user to use the rear selfie function, so that the user can understand how to use the rear selfie function and improve the user experience.

[0035] In one possible implementation, the method also includes: in response to a sixth operation performed by the user on a blank area of ​​the first photo preview interface, the first guide information disappears, and a fifth photo preview interface is displayed through the first screen, the fifth photo preview interface including an image obtained through the rear camera, a second control, second guide information and a sliding guide animation, and the second guide information and the sliding guide animation are used to guide the user to perform a sliding operation on the second control.

[0036] The sixth operation may be, for example, clicking on a blank area of ​​the first photo preview interface. The blank area refers to a location in the interface that does not contain controls or guidance information.

[0037] That is to say, when the camera application first enters the rear non-selfie scene in the folded state, the user can be guided to perform a sliding operation on the second control through the second guidance information and the sliding guidance animation. This makes it easier for users to understand the rear selfie function and how to enter the rear selfie function, and facilitates users to enter the rear selfie function, thereby making the selfie effect better and improving the user experience.

[0038] In one possible implementation, the method also includes: in response to the user performing the seventh operation on the second control in the fifth photo preview interface, displaying a sixth photo preview interface through the first screen, and displaying the image obtained through the front camera, the second control, the second guide information and the sliding guide animation in the sixth photo preview interface.

[0039] The seventh operation may be, for example, clicking the second control in the fifth photo preview interface.

[0040] That is, when the camera app first enters the front-facing selfie scene in the folded state, the user can also be guided to perform a sliding operation on the second control through the second guidance information and the sliding guidance animation. The camera app is in the front-facing selfie scene, which means that the user is taking a selfie, and the user is more likely to use the rear-facing selfie function. Therefore, in this implementation, when the user first enters the front-facing selfie scene in the folded state, the user is guided to perform a sliding operation to call out the first control (i.e., the rear-facing selfie control), so that the user can understand the rear-facing selfie function and how to enter the rear-facing selfie function, and can easily enter the rear-facing selfie function, thereby making the selfie effect better and improving the user experience.

[0041] In one possible implementation, displaying the first photo preview interface on the first screen includes: displaying the first photo preview interface in response to the user starting the camera application, and displaying the first control and the second control tiled in the first photo preview interface.

[0042] In this implementation, the first control and the second control are displayed flatly in the first photo preview interface, and the user can see the controls intuitively, which is convenient for the user to select rear-facing selfie or front-facing selfie according to usage needs, making it easier to use and improving the user experience.

[0043] In one possible implementation, the first photo preview interface includes an image acquired through the rear camera, and the method further includes: in response to the user performing an eighth operation on the second control in the first photo preview interface, displaying a seventh photo preview interface, the seventh photo preview interface including the image acquired through the front camera, the first control, the second control and the third control, and the first control and the second control are displayed tiled in the seventh photo preview interface; in response to the user performing a ninth operation on the third control, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the second photo preview interface through the second screen.

[0044] The third control is the rear selfie switch.

[0045] Optionally, the eighth operation may be, for example, an operation of clicking a second control in the first photo preview interface. The ninth operation may be an operation of clicking a third control in the first photo preview interface.

[0046] In this implementation, the user can access the front-facing selfie scene in the folded state through the second control. In the preview interface of the folded front-facing selfie scene and the folded rear-facing non-selfie scene, the first and second controls are laid out in the same tiled format. This facilitates use and improves the user experience.

[0047] In addition, the seventh photo preview interface also includes a third control. Users can directly click the third control to enter the rear selfie function, which facilitates user operation and improves user experience.

[0048] In a possible implementation, the method further includes: if it is detected that the ambient light brightness is less than a preset threshold, displaying first guidance information in the seventh photo preview interface, where the first guidance information is used to guide the user to take a selfie using the rear camera.

[0049] The ambient light brightness is less than the preset threshold, which means that the electronic device is in a dark environment.

[0050] In the front-facing selfie scenario, if the electronic device is in a dark environment, the selfie effect will be worse. Therefore, in this implementation, the first guidance information is used to guide the user to use the rear-facing selfie function to take better selfie images, thereby improving the user experience.

[0051] Optionally, the first guidance information may be displayed only when the user has not used the rear selfie function to avoid disturbing the user.

[0052] 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 second 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 second photo preview interface is displayed through the second screen.

[0053] In this implementation, when entering the rear selfie function, before controlling the screen switching, a first flip guide interface is first displayed to guide the user to flip the electronic device, so that the user can learn how to use the rear selfie function and improve the user experience.

[0054] 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.

[0055] In a possible implementation, the shooting mode in the second photo preview interface is the same as the shooting mode in the first photo preview interface.

[0056] 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.

[0057] In a possible implementation, the second photo preview interface further includes third guidance information, and the third guidance information is used to guide the user to look at the rear camera.

[0058] The third guiding information is also the eye guidance information.

[0059] In this implementation, the third guidance information is used to guide the user to look at the rear camera, so that the image effect obtained by the rear selfie is better.

[0060] Optionally, the third guidance information may be displayed only when the user uses the rear selfie function for the first time to reduce disturbance to the user.

[0061] In one possible implementation, the electronic device also includes a flash, which is arranged on the same side as the rear camera, and the second photo preview interface also includes a flash switch. The method also includes: in response to the user's operation on the flash switch, displaying an eighth photo preview interface through the second screen, the eighth photo preview interface including an image obtained through the rear camera and a fourth control; in response to the user's operation on the fourth control, controlling the flash to be always on, and controlling the screen brightness of the second screen to be increased.

[0062] In this implementation, the rear selfie function supports super fill light at the same time. When using the rear selfie function, users can use the fourth control to turn on the super fill light function with one click to make the rear selfie effect better.

[0063] In one possible implementation, the second photo preview interface includes a fifth control and a sixth control. After the second photo preview interface is displayed through the second screen, the method further includes: in response to the user's operation on the fifth control or the sixth control, displaying a second flip guide interface through the second screen, 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, controlling the second screen to turn off and controlling the first screen to turn on, and displaying a ninth photo preview interface through the first screen, the ninth photo preview interface including the image obtained through the rear camera and the second control.

[0064] Optionally, the fifth control may be, for example, a home screen switch control. The sixth control may be a rear selfie exit control.

[0065] In this implementation, after entering the rear-mounted selfie function, the user can exit the function with one click using the fifth or sixth control, facilitating user operation and usage, and improving the user experience. Furthermore, when exiting the rear-mounted selfie function, a second flip guidance interface is displayed before the screen is switched to guide the user in flipping the electronic device, allowing the user to easily understand how to exit the rear-mounted selfie function, thereby improving the user experience.

[0066] In one possible implementation, the second screen is controlled to turn off and the first screen is controlled to turn on. After the ninth photo preview interface is displayed on the first screen, the method also includes: if the first function has not been turned on, a second pop-up window is displayed on the first screen, and the second pop-up window is used for the user to choose whether to turn on the first function.

[0067] Optionally, the first function may be a flip wake-up function.

[0068] In this implementation, if the user has not activated the first function, after the user exits the rear selfie function, a second pop-up window will appear asking the user whether to activate the first function. This makes it easier for users who do not frequently use the camera settings control and are not familiar with camera functions to promptly learn about the first function and activate it.

[0069] Optionally, the second pop-up window may be displayed after the user uses the rear-mounted selfie function for the first time.

[0070] In one possible implementation, after displaying the second pop-up window, the method also includes: in response to the user turning on the first function through the second pop-up window, closing the second pop-up window, and displaying the ninth photo preview interface; in response to the user flipping the electronic device, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the second photo preview interface through the second screen.

[0071] That is to say, in this implementation, after the user turns on the flip wake-up function, the user can enter the rear selfie function by flipping the electronic device. The user does not need 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.

[0072] In one possible implementation, in response to the user flipping the electronic device, controlling the first screen to turn off and controlling the second screen to turn on, and displaying the second photo preview interface through the second screen, the method also includes: in response to the user flipping the electronic device, controlling the second screen to turn off and controlling the first screen to turn on, and displaying the ninth photo preview interface through the first screen.

[0073] In this implementation, the user can exit the rear-mounted selfie function by flipping the electronic device, without the user having to click to switch the main screen controls or the rear-mounted selfie exit controls in the interface. The rear-mounted selfie function can be exited quickly and conveniently, thereby improving the intelligence of the electronic device and thereby improving the user experience.

[0074] In one possible implementation, the second screen is controlled to turn off and the first screen is controlled to turn on. After the ninth photo preview interface is displayed on the first screen, the method further includes: if the layout of the first control and the second control in the photo preview interface has not been switched, a third pop-up window is displayed on the first screen, and the third pop-up window is used for the user to choose whether to switch the layout.

[0075] In this implementation, if the user has not switched the layout mode (i.e., the selfie entry mode), the user is guided to switch the layout mode. This allows users who do not frequently use the camera settings controls and are not familiar with camera functions to promptly understand that the layout mode is switchable and to directly switch the layout mode, thereby facilitating the use of the rear-mounted selfie function.

[0076] Optionally, the third pop-up window may be displayed after the user uses the rear selfie function for the second time, so that it can be displayed sequentially with the first pop-up window in the above embodiment, thereby preventing multiple pop-up windows from being displayed to the user at one time and affecting the user experience.

[0077] In one possible implementation, after displaying the third pop-up window through the first screen, the method further includes: in response to the user switching the layout mode to the second mode through the third pop-up window, displaying first guidance information, the first guidance information being used to guide the user to take a selfie through the rear camera.

[0078] In this implementation, after the user switches the layout mode, the first guidance information is displayed to guide the user to use the rear selfie function, thereby improving the user experience.

[0079] Optionally, the first guidance information may be displayed only when the user switches the layout mode for the first time to reduce disturbance to the user.

[0080] In one possible implementation, the method further includes: when the second screen displays the second photo preview interface, in response to the user unfolding the electronic device to the unfolded state, controlling the first screen to light up, and jointly displaying the tenth photo preview interface through the first screen and the second screen, the tenth photo preview interface including the image obtained by the front camera.

[0081] The tenth photo preview interface is the interface of the front selfie scene in the expanded state.

[0082] In this implementation, the user unfolds the foldable screen phone to the expanded state while using the rear selfie function, indicating that the user needs to take a selfie in the expanded state. Therefore, directly entering the expanded front shooting scene is likely to meet the user's needs and improve the user experience.

[0083] In one possible implementation, the image acquired by the front camera is displayed in the first photo preview interface; the first photo preview interface is displayed through the first screen, including: when the electronic device is in the unfolded state, the tenth photo preview interface is jointly displayed through the first screen and the second screen, in response to the user folding the electronic device to the folded state, the first screen is controlled to light up, and the second screen is controlled to turn off, and the first photo preview interface is displayed through the first screen.

[0084] That is to say, in this implementation, the first photo preview interface is the interface of the front selfie scene in the folded state, and the tenth photo preview interface is the interface of the front selfie scene in the expanded state.

[0085] In this implementation, in the unfolded front-facing selfie scenario, the phone is folded directly. The foldable screen phone responds to the user's operation and enters the folded front-facing selfie scenario. Afterwards, the user can access the rear-facing selfie function by clicking the rear-facing selfie control or flipping the phone to wake it up.

[0086] In one possible implementation, the method also includes: when the second screen displays the second photo preview interface, in response to the user's tenth operation 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 user's eleventh operation 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 second photo preview interface through the second screen.

[0087] The tenth operation is to exit the camera app to the background, for example, by clicking the home button in the three-button navigation bar, or swiping up from the bottom of the screen, or swiping up a certain distance from the bottom of the screen and pausing to enter the multitasking interface, where the user taps the interface thumbnail of another task (app). The eleventh operation is to bring the camera app back to the foreground, for example, by tapping the camera app icon.

[0088] In this implementation, if the user exits the camera app and puts it in the background, the electronic device can retain the memory of the camera app. When the user restarts 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.

[0089] In one possible implementation, the second photo preview interface includes a seventh control, and the seventh control includes a thumbnail. The method also includes: when the second photo preview interface is displayed on the second screen, in response to the user clicking the seventh control, the first interface is displayed through the second screen, and the first interface includes an image corresponding to the thumbnail.

[0090] The seventh 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.

[0091] In this implementation, while using the rear-mounted selfie function, users can view captured images through the image thumbnails in the second photo preview interface. Images can be displayed on the second screen. This allows users to view images at any time without exiting the rear-mounted selfie function, facilitating user experience and improving user experience.

[0092] 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.

[0093] The second interface is the image preview interface in the expanded state.

[0094] 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.

[0095] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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 phone 10. It is understood that the secondary screen 121 and the main screen 111 can actually be a single, integrally formed flexible display screen (i.e., a foldable screen). When the foldable screen 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 are located on the same side of the connecting assembly.

[0140] 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 sub-screen 121 are approximately in the same plane, that is, the main screen 111 and the sub-screen 121 are on the same side. In the unfolded state, the light emitting direction of the main screen 111 and the sub-screen 121 is the same as the light incoming direction of the rear camera. In the unfolded state, the foldable screen mobile phone 10 displays the content to be displayed through the main screen 111 and the sub-screen 121 at the same time. Optionally, in the unfolded state, the main screen 111 and the sub-screen 121 can jointly display the interface of the same application, or can display the interfaces of different applications in split screens.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] For example, FIG6 is a schematic structural diagram of an electronic device 100 provided in an embodiment of the present application.

[0152] The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 124, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a proximity light sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M and an angle sensor 180N, etc.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] The angle sensor 180N 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.

[0165] 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.

[0166] 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.

[0167] Ambient light sensor 180L is used to sense ambient light brightness. Electronic device 100 can adaptively adjust the brightness of display screen 194 based on the perceived ambient light brightness. Ambient light sensor 180L can also be used to automatically adjust white balance when taking photos. In embodiments of the present application, in front-facing selfie scenarios, ambient light sensor 180L can detect ambient brightness to determine whether to display rear-facing selfie guidance information.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] The application framework layer 220 provides an application access interface and a programming framework for the applications of the application layer 210 .

[0173] 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.

[0174] 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.

[0175] The camera device in the application framework layer 220 is used to provide a data access interface between different camera devices and camera management.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] The following describes the workflow of the software system of the electronic device 100 in conjunction with a photo-taking scenario.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] To facilitate understanding, several terms involved in the following embodiments are first explained.

[0185] 1. Enable the function

[0186] 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 function, the function is said to be in the on state, the turned-on state, or the function is turned on. It is understandable that some functions need to be turned on by turning on a switch to be in the on state, such as the smile capture function of the camera application. Some functions are in a continuously on state and do not need to be turned on and off, such as the camera's shooting function, the rear selfie function, the flip camera function, etc.

[0187] 2. Turn off the function

[0188] 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.

[0189] 3. Enter function

[0190] 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.

[0191] 4. Exit function

[0192] 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.

[0193] In this application, the camera application in a foldable phone features a rear-mounted selfie function. Users can use the rear-mounted camera to take selfies, improving the quality and effect of the selfie images. The following describes the relevant process based on the use stages of the rear-mounted selfie function and the application scenarios.

[0194] 1. Selfie entry method

[0195] 1. Introduction to selfie entry methods

[0196] In an embodiment of the present application, the selfie function may include a front selfie function and a rear selfie function. The selfie entrance is the entrance to the front selfie function and / or the entrance to the rear selfie function. In a specific embodiment, the entrance to the front selfie function may be a flip camera control (also referred to as a second control), and the entrance to the rear selfie function may be a rear selfie control (also referred to as a first control). The selfie entrance method refers to the display method (also referred to as the layout method) of the entrance to the front selfie function and the entrance to the rear selfie function. Therefore, the selfie entrance method is essentially the display method of the flip camera control and the rear selfie control.

[0197] Optionally, there may be multiple selfie entry modes, such as a sliding mode (also referred to as the first mode) and a flat mode (also referred to as the second mode). These modes will be described below in conjunction with the accompanying drawings.

[0198] For example, FIG8 is a schematic diagram of an interface change using a sliding selfie entry provided in an embodiment of the present application. As shown in FIG8 (a), the foldable screen mobile phone is in the folded state, the secondary screen is in the off state, and when the selfie entry mode is sliding, after the camera application is started, the foldable screen mobile phone obtains an image through the rear camera and displays a photo preview interface 908 through the main screen. The photo preview interface 908 includes the image obtained by the rear camera, and the photo preview interface 908 displays a sliding selfie entry. In other words, the photo preview interface 908 is a preview interface for the rear non-selfie scene in the folded state and the sliding selfie entry mode.

[0199] The sliding selfie entrance can also be called a sliding shortcut menu, including a flip camera control 909 and a sliding indicator arrow 910. The flip camera control 909 is used by the user to control the switching between the rear camera and the front camera. The user clicks the flip camera control 909, the folding screen mobile phone flips the camera, enters the front selfie scene in the folded state, obtains the image through the front camera, and displays the corresponding photo preview interface through the main screen. The front selfie scene refers to the scene taken by the front camera. For the photo preview interface of the front selfie scene in the folded state, please refer to Figure (b) in Figure 14 in the subsequent embodiments.

[0200] The slide indicator arrow 910 is used to prompt the user to perform a slide operation to call out the rear selfie control. In some embodiments, the slide indicator arrow 910 can be displayed continuously with an animation effect to prompt the user that a slide is allowed here. In other embodiments, the slide indicator arrow 910 can also be displayed with an animation effect only in preset scenarios and displayed statically in other scenarios. For example, in the folded state, when the user switches from the front selfie shooting scene to the rear non-shooting scene, or when the user switches from the rear non-shooting scene to the front selfie shooting scene, the slide indicator arrow 910 is displayed with an animation effect.

[0201] The user can slide in the direction of the sliding indication arrow 910 at the flip camera control 909 (i.e., slide upward). In response to the user's operation, the folding screen mobile phone calls out the rear selfie control 902. Specifically, the folding screen mobile phone displays a photo preview interface 912, as shown in Figure (b) of Figure 8. The photo preview interface 912 includes a first capsule 911. The first capsule 911 includes a rear selfie control 902 and a flip camera control 909. The change process from Figure (a) in Figure 8 to Figure (b) in Figure 8 is similar to expanding the sliding shortcut menu, calling out the hidden rear selfie control 902, and displaying the flip camera control 909 and the rear selfie control 902 in the interface at the same time.

[0202] The user can choose to click the rear Selfie control 902 to enter the rear Selfie function according to needs, or click the flip camera control 909 to enter the front Selfie function. The process of entering the rear Selfie function will be further described in subsequent embodiments.

[0203] If the user does not click on the rear selfie control 902 or the flip camera control 909 after the first capsule 911 is displayed for the preset time, that is, the user does not operate the first capsule 911 within the preset time, the sliding shortcut menu will be retracted, the rear selfie control 902 will be hidden, and the interface will be restored to the photo preview interface 908, as shown in Figure 8 (c).

[0204] In this implementation, on the one hand, the user can call out the rear selfie control by sliding, and then can choose the rear selfie or the front selfie according to usage needs, which is convenient for user use and improves the user experience; on the other hand, the flip camera control is a control that the user is more familiar with. When the user does not perform the swipe up gesture, the rear selfie control is not displayed in the interface, and only the flip camera control and the sliding indicator arrow are displayed. This not only conforms to the user's usage habits, but also has fewer controls, which facilitates the arrangement of controls in the interface, prevents it from affecting other controls in the user operation interface, and further improves the user experience.

[0205] For example, FIG9 is a schematic diagram of an interface of a tiled selfie entrance provided in an embodiment of the present application. As shown in FIG9 , when the foldable screen mobile phone is in the folded state, the secondary screen is in the off state, and the selfie entrance mode is tiled, after the camera application is started, the foldable screen mobile phone obtains an image through the rear camera, and displays a photo preview interface 913 through the main screen. The photo preview interface 913 includes the image obtained by the rear camera. The photo preview interface 913 also includes a second capsule 914. The second capsule 914 displays a flip camera control 909 and a rear selfie control 902 tiled. The user can choose to click the rear selfie control 902 to enter the rear selfie function, or click the flip camera control 909 to enter the front selfie scene in the folded state according to needs.

[0206] In other words, the photo preview interface 913 is a preview interface of the rear non-selfie scene under the folded, flat selfie entrance.

[0207] In this implementation, the rear selfie control 902 and the flip camera control 909 are displayed flatly in the interface, and the user can see the controls intuitively, which is convenient for the user to choose the rear selfie or the front selfie according to the usage needs, which is convenient to use and improves the user experience.

[0208] The above-mentioned photo preview interface 908 and photo preview interface 913 are also collectively referred to as the ninth photo preview interface.

[0209] 2. Switching the selfie entry method

[0210] Optionally, the default selfie entry mode of the foldable screen mobile phone when it leaves the factory can be a sliding mode. The user can switch the selfie entry mode according to needs. In one embodiment, the user can switch the selfie entry mode through the camera settings.

[0211] For example, Figure 10 is a schematic diagram of an interface change for switching the selfie entry mode provided in an embodiment of the present application. Taking a foldable screen mobile phone in the folded state and the current selfie entry mode as a sliding mode as an example, after the camera application is started, a photo preview interface 908 is displayed on the main screen. The photo preview interface 908 includes an image captured by the rear camera, and the photo preview interface 908 includes a flip camera control 909 and a sliding indicator arrow (also known as an operation guide mark) 910, as shown in Figure 10 (a).

[0212] The photo preview interface 908 also includes a camera settings control 903. When a user taps on the camera settings control 903, the foldable phone responds by displaying a camera settings interface 904, as shown in FIG10(b). The camera settings interface 904 includes a selfie entry mode option (also referred to as the first option) 905. The selfie entry mode option 905 is currently displayed as "sliding."

[0213] The user clicks on the selfie entry method option 905, and the foldable screen mobile phone responds to the user's operation and displays a selfie entry method setting pop-up window (also called the first pop-up window) 906, as shown in Figure (c) in Figure 10.

[0214] The selfie entry mode setting pop-up window 906 includes a sliding option (also known as the second option) 9061, a tile option (also known as the third option) 9062, and an OK control 9063. As shown in FIG10(c), the sliding option 9061 is currently selected and highlighted, while the tile option 9062 is not selected and is not highlighted.

[0215] The user clicks on the tiled option 9062, and the foldable screen phone responds to the user's operation by highlighting the tiled option 9062 and de-highlighting the sliding option 9061, as shown in Figure (d) in Figure 10.

[0216] Afterwards, the user clicks the confirmation control 9063, and the foldable screen phone responds to the user's operation by switching the selfie entry mode to the tiled mode. The selfie entry mode setting pop-up window 906 closes, and the foldable screen phone displays the camera settings interface 904. At this time, the selfie entry mode option 905 in the camera settings interface 904 is displayed as "tile", as shown in Figure 10 (e).

[0217] Afterwards, the user performs a return operation, and the mobile phone responds to the user's operation and displays a photo preview interface 913. The photo preview interface 913 includes a second capsule 914, in which a flip camera control 909 and a rear selfie control 902 are tiled, as shown in Figure (f) in Figure 10. Optionally, the return operation can be, for example, a side-sliding 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. This embodiment of the application does not impose any restrictions on this. The same is true for subsequent embodiments and will not be repeated here.

[0218] The process of switching the selfie entry mode from flat to sliding is similar to the above process and will not be repeated here.

[0219] It should be noted that the selfie entry method is effective for both the front selfie scene and the rear non-selfie scene in the folded state. In other words, the selfie entry method for the front selfie scene and the rear non-selfie scene in the folded state are synchronized.

[0220] In this embodiment, the user can independently switch the selfie entry mode in the camera settings as needed to meet the usage needs of different users, facilitate user operation, and improve user experience.

[0221] 2. Setting the flip wake-up function

[0222] In an embodiment of the present application, 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, also referred to as the first 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 raises the phone to face the face and looks at the screen according to the flip wake-up requirement, the foldable screen mobile phone recognizes the face through the front camera, and then the user flips the phone. The foldable screen mobile phone detects that the user flips the phone through the sensor, and after recognizing the face through the rear camera, it triggers the camera application to automatically enter the rear selfie function.

[0223] The following is a brief description of the setting process of the flip wake-up function with reference to the accompanying drawings.

[0224] 1. Turn on the flip wake-up function

[0225] For example, Figure 11 is a schematic diagram of the interface changes for setting the flip wake-up function provided in an embodiment of the present application. As shown in Figure 11 (a), when the foldable screen mobile phone is in the folded state, after the camera application is started, the user can enter the camera settings interface 904 by following the process shown in Figures (a) to (b) in Figure 10 above. The specific process is shown in the embodiment shown in Figure 10 and will not be repeated here.

[0226] The camera settings interface 904 includes a flip wake-up rear selfie option 1001. The user clicks on option 1001 to enter the flip wake-up rear selfie settings interface (referred to as the flip wake-up settings interface) 1002, as shown in Figure 11 (b). The flip wake-up settings interface 1002 includes a switch control for the flip wake-up rear selfie function (referred to as the flip wake-up switch) 1003. The flip wake-up switch 1003 is in the off state by default and is displayed in gray. The user clicks on the flip wake-up switch 1003, and the foldable screen phone responds to the user's operation to turn on the flip wake-up function, and the flip wake-up switch 1003 is highlighted, as shown in Figure 11 (c).

[0227] Afterwards, the user performs two return operations, and the foldable screen mobile phone exits the flip wake-up setting interface 1002 and the camera setting interface 904 in succession, and restores the display of the photo preview interface 908, as shown in Figure (d) in Figure 11.

[0228] 2. Turn off the flip wake function

[0229] The deactivation process of the flip wake-up function is similar to the activation process described above, except that the deactivation process switches the flip wake-up switch 1003 from the on state to the off state, which will not be described in detail here.

[0230] In this embodiment, the user can independently set the flip wake-up function to be on or off as needed, meeting the user's different usage habits and usage needs in different scenarios, facilitating user operation and improving user experience.

[0231] 3. Entering and exiting the rear selfie function

[0232] When the user is using the camera application, he can enter the rear selfie function (that is, enable the rear selfie function) through the corresponding operation. After entering the rear 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 second 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 selfie scenario, that is, the photo preview interface when using the rear 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 selfie function, the user can perform selfie-related operations through the secondary screen, which is convenient to use and further improves the user experience.

[0233] After entering the rear-camera selfie function, the user can also exit it through the corresponding operation. After exiting the rear-camera selfie function, the camera application enters the rear-camera non-selfie mode in the folded state. The foldable screen phone turns off the secondary screen and displays the corresponding photo preview interface on the main screen, such as Figure 8 (a) or Figure 9. In other words, after entering the rear-camera selfie function, the user can exit it at any time, which facilitates user operation and usage and improves the user experience.

[0234] In the embodiments of the present application, several methods of entering and exiting the rear-mounted selfie function are provided, which are described below respectively.

[0235] 1. Enter and exit the rear selfie function through the control

[0236] For example, Figure 12 is a schematic diagram of the interface changes for entering the rear selfie function provided in an embodiment of the present application. As shown in Figure 12 (a), when the foldable screen phone is in the folded state, the secondary screen of the foldable screen phone is in the off state and the main screen is in the bright state. Taking the selfie entry method selected by the user as the tiled mode as an example, the main screen displays the photo preview interface 913.

[0237] It should be noted that, generally, when the phone is folded, with the main screen on and the secondary screen off, the user will turn the main screen of the phone toward the user and the secondary screen (i.e., the side with the rear camera) away from the user. This example is used in the embodiments of this application to facilitate description of the situation before and after the user flips the phone.

[0238] The user clicks on the rear selfie control 902 in Figure 12 (a). In response to the user's operation, the foldable screen mobile phone displays a flip guidance interface 1105 (also called a first flip guidance interface) on the main screen, as shown in Figure 12 (b). 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 a text prompt message 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 flipping phone, so as to more clearly guide the user to flip the phone and improve the user experience. Optionally, the text prompt message 1151 may be, for example, "Please flip the phone to use the rear selfie."

[0239] 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 displaying the flip guide interface 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 entry or exit of the rear selfie function, thereby improving the user experience.

[0240] After the flip guide interface 1105 is displayed for a preset time (for example, 3 seconds), the camera application enters the rear selfie function. Specifically, the folding screen mobile 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 through the secondary screen. The photo preview interface 1106 includes the image acquired by the rear camera. After the user flips the folding screen mobile phone, the side where the secondary screen is located (that is, 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 (that is, the selfie image) acquired by the rear camera can be displayed in the photo preview interface 1106, as shown in Figure (c) in Figure 12.

[0241] Optionally, in some other embodiments, when the main screen displays the flip guide interface 1105, the secondary screen may light up at the same time, 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 main screen displays the flip guide interface 1105 while the secondary screen lights up, and displays the photo preview interface 1106 on the secondary screen.

[0242] Optionally, while the secondary screen displays the flip guide interface 1105, the foldable screen mobile phone can block the touch functions of both the main screen and the secondary screen. That is, the touch functions of the main screen and the secondary screen are 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.

[0243] 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.

[0244] 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 913. 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.

[0245] For example, FIG13 is a schematic diagram of an interface change for exiting the rear-mounted selfie function provided in an embodiment of the present application. Continuing with FIG12(c), as shown in FIG13(a), the photo preview interface 1106 includes a home screen switch control (also known as the fifth control) 1108 and a rear-mounted selfie exit control (also known as the sixth control) 1109. When a user clicks the home screen switch control 1108 or the rear-mounted selfie exit control 1109, the foldable phone displays a flip guide interface 1301 (also known as a second flip guide interface) on the secondary screen in response to the user's operation, as shown in FIG13(b). Flip guide interface 1301 is used to guide the user to flip the foldable phone so that the primary screen faces the user and the secondary screen (i.e., the side with the rear camera) faces away from the user. Optionally, flip guide interface 1301 may include text prompts 1311, an arrow 1312 indicating the flip direction, and a schematic diagram 1313 of the foldable phone. Optionally, multiple schematic diagrams of foldable phones at different angles can be displayed continuously to present a dynamic image of flipping the phone in the flip guidance interface 1301, so as to more clearly guide the user to flip the phone and improve the user experience. Optionally, in this interface, the text prompt message 1311 can be, for example, "The rear selfie has exited, please flip the phone."

[0246] After the flip guide interface 1301 displays 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 the photo preview interface 913 on the main screen. The photo preview interface 908 includes the image captured by the rear camera. After the user flips the phone, the photo preview interface 913 can display the image of the surrounding people or objects captured by the rear camera, as shown in Figure 13 (c).

[0247] In this implementation, when using the rear selfie function, the user can exit the function at any time by switching the main screen control 1108 or the rear selfie exit control 1109 with one click. The operation is convenient and simple, which improves the user experience.

[0248] In another embodiment, in the front-facing selfie scenario, the user can access the rear-facing selfie function through a rear-facing selfie switch (also known as a permanent rear-facing selfie control or a third control). Specifically, when the camera application is in the front-facing selfie scenario, the photo preview interface may further include a rear-facing selfie switch. The rear-facing selfie switch can be used to control the activation of the rear-facing selfie function. This is described below with reference to the accompanying drawings.

[0249] For example, Figure 14 is a schematic diagram of the interface changes during the process of entering the rear selfie function through the rear selfie switch provided in an embodiment of the present application. As shown in Figure 14 (a), taking the sliding selfie entry method as an example, the foldable screen 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 908. The photo preview interface 908 includes the image captured by the rear camera.

[0250] The photo preview interface 908 includes a flip camera control 909. When the user clicks on the flip camera control 909, the user enters the folded front-facing selfie scene and displays a photo preview interface 1401 (also known as the seventh photo preview interface). The photo preview interface 1401 includes an image captured by the front camera, the flip camera control 909, and a slide indicator arrow 910, as shown in FIG14(b). In addition, the photo preview interface 1401 also includes a rear-facing selfie switch (also known as the third control) 1402.

[0251] The user clicks the rear selfie switch 1402. In response to the user's operation, the foldable screen mobile phone displays a flip guide interface 1105 through the main screen, as shown in Figure 14 (c).

[0252] 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 14 (d).

[0253] In this embodiment, in the front selfie scenario, the interface includes a rear selfie switch, and the user can directly click the rear selfie switch to enter the rear selfie function, which is convenient for user operation and improves user experience.

[0254] In the embodiment of the present application, the photo preview interface 908 and the photo preview interface 1401 may also be collectively referred to as a third photo preview interface.

[0255] 2. Flip the phone to wake up or exit the rear selfie function

[0256] As mentioned above, the camera application of a foldable screen mobile phone can have a flip wake-up function. When the flip wake-up function is turned on (refer to Figure 11 for the turning-on process), 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. After entering the rear selfie function, the user can also exit the rear selfie function by flipping the phone. In this way, the user does not need to perform operations such as clicking on the rear selfie control, the rear selfie exit control, etc. in the interface, and can quickly and conveniently enter or exit 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.

[0257] For example, FIG15 is a schematic diagram of the interface changes for entering and exiting the rear selfie through the flip wake-up function provided in an embodiment of the present application. As shown in FIG15 (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 does not enter the rear selfie function, the main screen displays the photo preview interface 913. 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.

[0258] 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 15 (b).

[0259] When the user wishes to exit the rear-mounted selfie function, the user can reverse the above process, lifting the foldable phone so that the secondary screen of the foldable phone is facing the face and the user looks at the screen. The foldable phone then flips 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 the user flipping the phone, and recognizes the face through the front camera. The rear-mounted selfie function is then exited, the secondary screen turns off, the main screen turns on, and a photo preview interface 913 is displayed on the main screen, as shown in Figure 15 (c).

[0260] 4. Function Usage Guide

[0261] In the embodiment of the present application, for some functions of the camera application, when the user is not using them, guidance information can be displayed to the user at an appropriate time to guide the user to understand and use these functions, thereby improving the user experience. The following describes the usage guidance of the rear selfie function and its related functions in combination with usage scenarios.

[0262] 1. Usage guidance when using the camera app for the first time in folded state

[0263] When a user launches the camera application of a foldable screen phone in the folded state for the first time, the foldable screen phone can guide the user to use the rear selfie function and guide the user to slide out the rear selfie control by swiping up to enter the selfie entrance.

[0264] For example, FIG16 is an interface diagram of the process of using the camera application for the first time in the folded state provided by an embodiment of the present application. Taking the sliding type as an example of the default selfie entry method of the foldable screen mobile phone when it leaves the factory, as shown in FIG16 (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 bright state, and the main screen displays the main interface 1601. The main interface 1601 includes an icon 1602 of the camera application. The user clicks the icon 1602 of the camera application. This operation is the first time the user triggers the launch of the camera application in the folded state. In response to the user's operation, the foldable screen mobile phone defaults to the rear non-selfie scene in the folded state, starts the rear camera to acquire an image, and displays the photo preview interface 1603 through the main screen, as shown in FIG16 (b). Unlike the aforementioned photo preview interface 908, in photo preview interface 1603, if the user does not swipe up on flip camera control 909, flip camera control 909 and rear selfie control 902 are directly displayed in first capsule 911, similar to FIG8 (b). Simultaneously, guidance information for the rear selfie function (referred to as rear selfie guidance information, also referred to as first guidance information) 1604 is displayed on rear selfie control 902. Rear selfie guidance information 1604 guides the user in using the rear selfie function, helping the user understand how to use it and improving the user experience.

[0265] Optionally, the rear-camera selfie guidance information 1604 may be displayed in the form of bubbles, cards, capsules, etc. The rear-camera selfie guidance information 1604 may include prompt text or prompt images to introduce the rear-camera selfie function. For example, in Figure 16 (b), the rear-camera selfie guidance information 1604 may include a prompt image (a selfie image of a person) and prompt text such as "Use the rear-camera selfie super-sensitive image quality portrait lens to take better portrait effects."

[0266] Of course, if the default selfie entry mode of the foldable screen mobile phone when it leaves the factory is the flat style, the above-mentioned rear selfie guide information 1604 can also be displayed at the rear selfie control, which will not be repeated here.

[0267] It is understood that when the user uses the camera in the folded state for a non-first time (second time and each subsequent time), the rear selfie guide message 1604 may not be displayed, and the interface shown in Figure 8 (a) or Figure 9 may be directly displayed to prevent interruption to the user and further improve the user experience. The same is true for other guidance messages or prompt messages described in subsequent embodiments. They may be displayed a preset number of times and then not be displayed again, or after the user has used the function for which they are guided, etc., and will not be described in detail in subsequent embodiments.

[0268] Please continue to refer to Figure 16. As shown in Figure 16 (b), when the user taps a blank area (a location without controls or guidance information) in the photo preview interface 1603, the aforementioned post-selfie guidance information 1604 disappears, and a sliding guidance effect (also known as a sliding guidance animation) 1605 is displayed. In addition, guidance information for using the sliding selfie entry (simply referred to as the sliding guidance information, also known as the second guidance information) 1606 is displayed, as shown in Figures 16 (c) and (d) of Figure 16 for the photo preview interface 1607 (also known as the fifth photo preview interface).

[0269] Swipe-up guidance animation 1605 is an animation effect that slides upward from flip camera control 909, simulating the process of a user swiping up to trigger the rear-mounted selfie control. Both swiping-up guidance animation 1605 and sliding guidance information 1606 are used to guide users in understanding how to use the swipe-up selfie portal, improving the user experience.

[0270] Optionally, the sliding guidance information 1606 may be displayed in the form of a bubble, card, capsule, etc. The sliding guidance information 1606 may include prompt text for explaining how to use the swipe up selfie portal. For example, in Figures (c) and (d) of Figure 16 , the sliding guidance information 1606 may include prompt text such as "Swipe to use the 'rear selfie'."

[0271] If the user clicks on a blank area of ​​the photo preview interface 1607 , the upward sliding guidance effect 1605 and the sliding guidance information 1606 disappear, and the photo preview interface 908 shown in FIG. 8 ( a ) is displayed.

[0272] If the user refers to the upward sliding guide effect 1605 and performs an upward sliding operation, the upward sliding guide effect 1605 and the sliding guide information 1606 disappear, the rear selfie control is called out, and the photo preview interface 912 shown in Figure 8 (b) is displayed.

[0273] 2. Guidance for using the front-facing selfie function for the first time in folded state

[0274] When the user uses the front-facing selfie function of the camera for the first time in the folded state, the user can also be guided to swipe up on the selfie entrance to call out the rear-facing selfie controls.

[0275] For example, Figure 17 is a schematic diagram of the interface changes when using the front-facing selfie function for the first time in the folded state, provided by an embodiment of the present application. As shown in Figure 17 (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 908. The photo preview interface 908 includes an image captured by the rear camera.

[0276] The photo preview interface 908 also includes a flip camera control 909. The user clicks on the flip camera control 909. This operation is the first time the front selfie function is entered in the folded state. As shown in Figures (b) and (c) of Figure 17, in response to the user's operation, the foldable screen mobile phone enters the front selfie scene in the folded state for the first time, displaying a photo preview interface 1701 (also called the sixth photo preview interface). The photo preview interface 1701 includes an image captured by the front camera. Unlike the photo preview interface 1401 shown in Figure (b) of Figure 14, the photo preview interface 1701 displays an upward sliding guidance effect 1605 and sliding guidance information 1606.

[0277] If the user clicks on a blank area of ​​the photo preview interface 1701 , the upward sliding guidance effect 1605 and the sliding guidance information 1606 disappear, and the photo preview interface 1401 shown in FIG. 14 ( b ) is displayed.

[0278] If the user refers to the upward swipe guidance effect 1605 and performs an upward swipe operation, the upward swipe guidance effect 1605 and the sliding guidance information 1606 disappear, the rear selfie control is called out, and the photo preview interface 1702 shown in Figure 17 (d) is displayed. The photo preview interface 1702 includes a first capsule 911. The first capsule 911 includes the rear selfie control 902 and the flip camera control 909. The user can choose to click the rear selfie control 902 to enter the rear selfie function; or click the flip camera control 909 to return to the rear non-selfie state in the folded state, and the photo preview interface 908 shown in Figure 17 (a) will be redisplayed.

[0279] When a user uses the front-camera selfie function, it indicates that the user is currently taking a selfie, and is more likely to use the rear-camera selfie function. Therefore, in this implementation, when a user first uses the front-camera selfie function, the user is guided to swipe up to call out the rear-camera selfie control. This helps the user understand the rear-camera selfie function and how to access it, making it easier for the user to access the rear-camera selfie function, thereby achieving better selfie results and improving the user experience.

[0280] In other embodiments, the swipe-up guidance animation 1605 and the sliding guidance information 1606 may also be displayed when the user switches shooting modes, for example, when the user switches shooting mode from still mode to portrait mode. In this case, the user is more likely to use the rear-mounted selfie function, so guiding the user to swipe up to call out the rear-mounted selfie control makes it easier for the user to understand the rear-mounted selfie function and how to access it, thereby improving the user experience.

[0281] 3. User guidance after switching to the selfie entry method for the first time

[0282] As described in the above embodiment, the user can switch the selfie entry mode in the camera settings. In one embodiment, after the user switches the selfie entry mode for the first time, the user can be guided to use the rear selfie function.

[0283] For example, FIG18 is a schematic diagram of a user guidance interface after switching the selfie entry mode for the first time, provided in an embodiment of the present application. Referring also to FIG10 , if the process shown in FIG10 (a) to FIG10 (e) is the user switching the selfie entry mode to the tiled mode for the first time, then the user performs a return operation in the interface shown in FIG10 (e), and the foldable screen mobile phone responds to the user's operation by displaying the photo preview interface 1801 shown in FIG18 . The photo preview interface 1801 includes an image captured by the rear camera. Unlike the photo preview interface 913 shown in FIG10 (f) above, the photo preview interface 1801 includes rear selfie guidance information 1604.

[0284] If the user clicks on a blank area of ​​the photo preview interface 1801 , the rear selfie guide information 1604 disappears, and the photo preview interface 913 shown in FIG. 10 ( f ) is displayed.

[0285] If the user clicks the flip camera control 909 in the photo preview interface 1801, the user enters the front selfie scene and displays the photo preview interface 1401 shown in Figure 14 (b).

[0286] If the user clicks on the rear selfie control 902 in the photo preview interface 1801, the rear selfie function is entered. The specific process is shown in Figure 12 above and will not be repeated here.

[0287] 4. Guidelines for using the front-facing selfie camera in dark environments

[0288] In one embodiment, if the user has not used the rear-facing selfie function and is currently in a front-facing selfie scene, when it is detected that the ambient light is dark, the user can be guided to use the rear-facing selfie function.

[0289] For example, Figure 19 is a schematic diagram of an example user interface for a front-facing selfie camera in a dark environment, provided by an embodiment of the present application. As shown in Figure 19, the foldable screen 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 front-facing selfie camera is in the scene. The main screen displays a photo preview interface 1901. Photo preview interface 1901 includes an image captured by the front camera.

[0290] Currently, the user has not used the rear-mounted selfie function. Furthermore, the foldable phone detects that it is currently in a low-light environment. Therefore, the photo preview interface 1901 also includes a rear-mounted selfie prompt 1902. Optionally, the rear-mounted selfie prompt 1902 can be displayed at the rear-mounted selfie switch 1402. Optionally, the rear-mounted selfie prompt 1902 can be displayed in a bubble or other form for a preset duration. The content of the rear-mounted selfie prompt 1902 can, for example, be "Use the rear-mounted super-sensitive lens for better selfies."

[0291] If the user clicks on a blank area of ​​the photo preview interface 1901 , the post-selfie prompt information 1902 disappears, and the photo preview interface 1401 shown in FIG. 14( b ) is displayed.

[0292] If the user refers to the rear selfie prompt information 1902 and clicks the rear selfie switch 1402, the rear selfie function is entered. The specific process is shown in Figures (b) to (d) in Figure 14 and will not be repeated here.

[0293] In the front-facing selfie scene, if the ambient light is dark, the shooting effect will be worse. Therefore, in this implementation, the user is prompted to use the rear-facing selfie function, guiding the user to take better selfie images through the rear-facing selfie function, thereby improving the user experience.

[0294] 5. Eye guidance when using the rear selfie function for the first time

[0295] When the user uses the rear selfie function for the first time, eye guidance information (also called third guidance information) can be displayed on the secondary screen to guide the user to look at the rear camera to make the image effect of the rear selfie better.

[0296] For example, Figure 20 is a schematic diagram of an eye guidance interface provided in an embodiment of the present application. As shown in Figure 20, the folding screen mobile phone enters the rear selfie function for the first time, the main screen is in the off state, the sub-screen lights up, and the sub-screen displays the photo preview interface 2001. The photo preview interface 2001 includes the image taken by the rear camera. Unlike the photo preview interface 1106 in Figure (c) of Figure 12 above, the photo preview interface 2001 includes eye guidance information 2002. Optionally, the eye guidance information 2002 can be displayed near the rear camera. Optionally, the eye guidance information 2002 can be displayed in the form of bubbles, etc. The content of the eye guidance information 2002 can be, for example, "Look at the camera area for more natural selfies".

[0297] If the user clicks on a blank area of ​​the photo preview interface 2001, the eye guidance information 2002 disappears and the photo preview interface 1106 as shown in FIG. 12(c) is displayed.

[0298] 6. After exiting the rear selfie function, it will ask whether to enable the flip wake-up function

[0299] In one embodiment, if the user has not previously enabled the flip wake-up function, after the user uses the rear-camera selfie function for the first time and exits, the user is asked whether to enable the flip wake-up function. This facilitates users who do not frequently use camera settings and are not familiar with camera functions to promptly learn about the flip wake-up function, enabling it, and thus facilitating their use of the rear-camera selfie function. Enabling the flip wake-up function means: prior to the current moment, the user enabled the flip wake-up function and subsequently disabled it; or prior to the current moment, the user enabled the flip wake-up function and subsequently did not disable it.

[0300] For example, FIG21 is a schematic diagram of an interface provided by an embodiment of the present application to inquire whether to turn on the flip wake-up function. Please refer to FIG13 as well. After the user uses the rear selfie function for the first time and exits the rear selfie function according to the process shown in FIG13, the photo preview interface 913 shown in FIG13 (c) is displayed. At this time, if the foldable screen mobile phone determines that the user has not turned on the flip wake-up function, the foldable screen mobile phone pops up an inquiry window (referred to as the flip wake-up inquiry window, also called the second pop-up window) 2101 asking whether to turn on the flip wake-up function, and displays the interface 2102 shown in FIG21.

[0301] The flip wake-up inquiry window 2101 may include introduction information 2103 of the flip wake-up function, a no longer prompt option 2104 , a cancel control 2105 and an enable control 2106 .

[0302] If the user clicks on the open control 2106, the foldable screen phone responds to the user's operation, closes the flip wake-up query window 2101, and turns on the flip wake-up function. The user can then enter or exit the rear selfie function by flipping the phone. For details, please refer to the process shown in Figure 15 and will not be repeated here.

[0303] It can be understood that after the user clicks on the turn-on control 2106, the flip wake-up switch 1003 in the flip wake-up rear selfie interface 1002 will be in the turned-on state and highlighted, as shown in Figure (c) in Figure 11.

[0304] If the user does not check the Do Not Prompt option 2104 and directly clicks the Cancel control 2105, the folding screen mobile phone responds to the user's operation, closes the flip wake-up inquiry window 2101, and does not turn on the flip wake-up function. Optionally, after the user clicks the Cancel control 2105, the folding screen mobile phone can also pop up the flip wake-up inquiry window 2101 again after the user subsequently exits the rear selfie function according to the preset pop-up logic. The preset pop-up logic may include, for example: the time interval between two adjacent pop-ups is not less than one week, the number of pop-ups is no more than 3 times, etc. Of course, the prerequisites for each pop-up of the flip wake-up inquiry window 2101 include: the user has not checked the Do Not Prompt option 2104, and the user has not turned on the flip wake-up function (whether it is turned on in the camera settings or turned on through the flip wake-up inquiry window 2101). The timing of each pop-up of the flip wake-up inquiry window 2101 is after exiting the rear selfie function.

[0305] If the user checks the "Do not prompt again" option 2104 and clicks the cancel control 2105, the foldable screen mobile phone responds to the user's operation, closes the flip wake-up inquiry window 2101, does not turn on the flip wake-up function, and the flip wake-up inquiry window 2101 will no longer pop up subsequently.

[0306] After the user turns on the flip wake-up function through the flip wake-up inquiry window 2101, the user can turn off the function in the camera settings. For details, please refer to Figure 11 and will not be repeated here.

[0307] 7. After exiting the rear selfie function, the user is prompted to switch to the selfie entry method.

[0308] In one embodiment, if the user hasn't switched to the selfie entry mode before, after the user uses the rear-mounted selfie function for the second time and exits, the user is prompted to switch to the selfie entry mode. This facilitates users who don't frequently use the camera settings controls and aren't familiar with camera functions to promptly learn that the selfie entry mode is switchable, allowing them to directly switch to the selfie entry mode, thus facilitating their use of the rear-mounted selfie function. Furthermore, in this embodiment, prompting the user to switch to the selfie entry mode after using the rear-mounted selfie function for the second time allows this to be performed sequentially with the inquiries about the flip wake-up function in the above-mentioned embodiment, preventing multiple functions from being recommended to the user at once and impacting the user's experience.

[0309] For example, Figure 22 is a schematic diagram of an interface for guiding the user to switch the selfie entry mode provided in an embodiment of the present application. Please refer to Figure 13 as well. After the user uses the rear-mounted selfie function for the second time, after exiting the rear-mounted selfie function according to the process shown in Figure 13, the photo preview interface 913 shown in Figure (c) of Figure 13 is displayed. At this time, if the foldable screen mobile phone determines that the user has not switched the selfie entry mode, the foldable screen mobile phone pops up a window (referred to as the entry guidance pop-up window, also known as the third pop-up window) 2201 to guide the user to switch the selfie entry mode, and displays the interface 2202 shown in Figure (a) of Figure 22.

[0310] Similar to the selfie entry mode setting pop-up window 906 shown in FIG. 10( c ), entry guidance pop-up window 2201 also includes a slide-style option 9061, a tile-style option 9062, and an OK control 9063. Unlike selfie entry mode setting pop-up window 906, entry guidance pop-up window 2201 includes a change location reminder message 2203 and a do not prompt option 2204. Change location reminder message 2203 reminds the user that the selfie entry mode can be modified in the camera settings.

[0311] If the user clicks on the tiled option 9062, the tiled option 9062 is highlighted and the sliding option 9061 is not highlighted, as shown in Figure 22 (b). Afterwards, the user clicks on the confirm control 9063, and the foldable screen mobile phone responds to the user's operation, closes the entry guide pop-up window 2201, and switches the selfie entry mode to the tiled mode. At the same time, the interface displays the rear selfie guidance information 1604, that is, the photo preview interface 1801 shown in Figure 22 (c) is displayed. It can be understood that after the above operation, the selfie entry mode option 905 in the camera setting interface 904 is displayed in the tiled mode, as shown in Figure 22 (d).

[0312] In this implementation, before the user switches the selfie entry mode through the above process, the user has not switched the selfie entry mode, that is, this switch is the first switch. Therefore, after the user completes the switch, the rear selfie guidance information 1604 is further displayed to guide the user to use the rear selfie function to improve the user experience.

[0313] If the user does not click on the tiled option 9062, that is, does not change the selfie entry method, and does not check the no longer prompt option 2204, and directly clicks the confirmation control 9063, then the folding screen mobile phone responds to the user's operation, closes the entry guidance pop-up window 2201, and the selfie entry method remains unchanged, and remains in the sliding mode, and the interface returns to the photo preview interface 913 shown in Figure 13 (c).

[0314] Optionally, in this case, the folding screen mobile phone can also pop up the entry guide pop-up window 2201 again according to the preset pop-up logic when the user subsequently exits the rear selfie function. The preset pop-up logic may include, for example, that the time interval between two adjacent pop-ups is not less than one week, and the number of pop-ups is at most 3 times. Of course, the prerequisites for each pop-up of the entry guide pop-up window 2201 include: the user has not checked the "no more prompts" option 2204, and the user has not switched the selfie entry method (whether switching in the camera settings or switching through the entry guide pop-up window 2201). The timing of each pop-up of the entry guide pop-up window 2201 is after exiting the rear selfie function.

[0315] If the user does not click on the tiled option 9062, that is, the selfie entry method is not changed, and the user checks the no longer prompt option 2204, and then clicks the confirmation control 9063, the folding screen mobile phone responds to the user's operation, closes the entry guide pop-up window 2201, the selfie entry method remains unchanged, and remains in the sliding type, and the entry guide pop-up window 2201 will no longer pop up subsequently.

[0316] After the user switches the selfie entry mode to the flat style through the above-mentioned entry guidance pop-up window 2201, the user can switch the selfie entry mode to the sliding style again in the camera settings. For details, please refer to Figure 10 and will not be repeated here.

[0317] 5. Super strong fill light when using the rear selfie function

[0318] In the embodiment of the present application, the rear selfie function supports super fill light when it is enabled. When using the rear selfie function, the user can turn on the super fill light function with one click, making the rear selfie effect better and further improving the user experience. The following is an explanation with reference to the accompanying drawings.

[0319] For example, Figure 23 is a schematic diagram of an interface change using super fill light, provided in an embodiment of the present application. As shown in Figure 23 (a), the foldable screen mobile phone is in the folded state, the rear selfie function is enabled, the main screen is off, and the secondary screen is on, and the image captured by the rear camera is displayed on the secondary screen. In other words, the secondary screen displays the photo preview interface 1106.

[0320] The photo preview interface 1106 includes a flash option 2301. When a user clicks on flash option 2301, the foldable screen phone expands the flash option in response to the user's operation, displaying automatic flash 2302, a flash off control 2303, a flash always-on switch 2304, and a super fill light switch (also known as the fourth control) 2305. See photo preview interface 2306 (also known as the eighth photo preview interface) in FIG23(b). Automatic flash 2302 is used to enable automatic flash mode. When this mode is enabled, the flash automatically turns on based on the surrounding lighting conditions. Flash off control 2303 is used to turn off the flash. When turned off, the flash does not function. Flash always-on switch 2304 is used to control the flash to always be on (i.e., the screen fill light is always on) for shooting fill light. Super fill light switch 2305 is used to control the activation of the super fill light function. The super fill light function means that the flash is always on and the brightness of the secondary screen is increased to provide a stronger fill light function. Optionally, the functions corresponding to the above four controls are independent and mutually exclusive. Users can choose one of them according to their needs.

[0321] The user clicks on the super fill light switch 2305. The foldable screen phone responds to the user's operation by turning on the super fill light function. The rear camera flash is constantly on, and the brightness of the secondary screen increases (shown as a grid filling in the figure). At the same time, the secondary screen displays the photo preview interface 2307 shown in Figure 23 (c). The photo preview interface 2307 includes the super fill light switch 2305, and the switch control is in a highlighted state, indicating that the super fill light function is currently turned on. In addition, the photo preview interface 2307 also includes a super fill light on prompt message 2308.

[0322] If the user wishes to disable the super fill light function, they can tap the super fill light switch 2305 in the photo preview interface 2307. In response to the user's action, the foldable phone displays a photo preview interface 2306, as shown in Figure 23(d). Photo preview interface 2306 is identical to Figure 23(b), except that in Figure 23(d), the super fill light function is enabled. Consequently, the rear camera flash remains constantly on, and the secondary screen is brighter.

[0323] The user then clicks the flash off control 2303 in the photo preview interface 2306, turning off the super fill light function. The photo preview interface 2309 is displayed, as shown in Figure 23 (e). The photo preview interface includes a flash off prompt 2310 to remind the user that the flash is currently off.

[0324] 6. After entering the rear selfie function, exit the camera application and return it to the background

[0325] After the user enters the rear-facing selfie function through the control, if the user exits the camera app and puts it in the background, the foldable screen phone can retain the running camera app for a preset period of time (for example, 15 minutes). That is, when the user re-activates the camera app within the preset period of time, the rear-facing selfie function will continue to operate. This simplifies user operations and improves the user experience by eliminating the need to repeatedly enter the rear-facing selfie function.

[0326] For example, FIG24 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 FIG24 (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. Among them, the operation of exiting the camera to the background may include, for example: a. Clicking the home button in the three-button navigation bar, or swiping up from the bottom of the screen; after the user performs this operation, the foldable screen mobile phone exits the camera application to the background and displays the main interface (also known as the desktop, main page, etc.). b. Swipe up from the bottom of the screen for a certain distance and pause to enter the multitasking interface. 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.

[0327] Taking the example of a user clicking the home button in the three-button navigation bar (not shown in Figure 24), in response to the user's operation, the folding screen mobile phone controls the secondary screen to turn off and controls the main screen to light up, and displays the main interface 1601 through the main screen, as shown in Figure (b) in Figure 24.

[0328] After performing other operations on the main screen, the user clicks the camera application icon 1602 on the main interface 1601 again within a preset time (e.g., 15 minutes). In response to the user's operation, the foldable screen phone launches the camera application and directly enters the rear selfie function, displaying the flip guide interface 1105, as shown in Figure 24 (c). After the flip guide interface 1105 is displayed for the preset time, the camera application enters the rear 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 24 (d). The photo preview interface 1106 includes the image captured by the rear camera.

[0329] In other embodiments, after entering the rear-mounted selfie function, if the user clicks the physical lock screen button to lock the screen, the foldable screen phone responds to the user's operation and exits the rear-mounted selfie function. The user then clicks the lock screen button again to turn on the screen, and the camera application automatically enters the rear-mounted non-selfie scene, displaying the photo preview interface 908 shown in Figure 8 (a) or the photo preview interface 913 shown in Figure 9, depending on the selfie entry method set by the user. Optionally, the mode after entering the rear-mounted non-selfie scene can inherit the shooting mode in the front and rear selfie scenes before the user locks the screen, improving the user experience.

[0330] 7. Unfolding the phone while using the rear selfie function

[0331] In this embodiment, when using 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 front-mounted selfie scene in the unfolded state. The front-mounted selfie scene in the unfolded state means that the foldable screen mobile phone obtains an image through the front camera, and displays the photo preview interface 2501 (also called the tenth photo preview interface) through the main screen and the sub-screen. The photo preview interface 2501 includes the image obtained by the front camera. In other words, the photo preview interface 2501 is the photo preview interface in the unfolded front-mounted selfie scene. When using the rear-mounted selfie function, the user unfolds the foldable screen mobile phone to the unfolded state, indicating that the user needs to take a selfie in the unfolded state. Therefore, directly entering the unfolded front-mounted shooting scene is likely to meet the user's usage needs and improve the user experience.

[0332] For example, Figure 25 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 25 (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.

[0333] The user unfolds the foldable phone, switching it to the unfolded state. In this manner, the main screen and secondary screen of the foldable phone face the user, while the first back housing, the second back housing, and the rear camera face away from the user. In response to the user's operation, the foldable phone captures an image through the front camera. Simultaneously, the secondary screen lights up, and the main and secondary screens jointly display a photo preview interface 2501, which includes the image captured by the front camera, as shown in FIG25(b).

[0334] Optionally, after the user unfolds the foldable screen phone through the above process and the foldable screen phone enters the unfolded front-facing selfie scene, the shooting mode can be consistent with the shooting mode when using the rear-facing selfie function, that is, the shooting mode in the photo preview interface 2501 is consistent with the shooting mode in the photo preview interface 1106. This can inherit the user's selection and improve the user experience.

[0335] 8. Viewing images while using the rear selfie function

[0336] In this embodiment, when a user uses the rear-mounted selfie function, the user can view the captured image through the image thumbnail (also known as the seventh control) 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 images at any time without exiting the rear-mounted selfie function, which is convenient for the user and improves the user experience.

[0337] Furthermore, when the user unfolds the foldable phone while viewing an image, the image is displayed on 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.

[0338] The following is a description with reference to the accompanying drawings.

[0339] For example, Figure 26 is a schematic diagram illustrating changes in the image viewing interface during use of the rear-mounted selfie function provided by an embodiment of the present application. As shown in Figure 26 (a), the 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 2601 of the image captured by the user.

[0340] When a user taps thumbnail 2601, the foldable phone displays an image preview interface 2602 (also called the first interface) on the secondary screen in response to the user's action. Image preview interface 2602 includes the image corresponding to thumbnail 2601, as shown in Figure 26(b). Additionally, image preview interface 2602 includes a favorites control 2621, a delete control 2622, a switch home screen control 2623, and a return control 2624. When a user taps the favorites control 2621, the foldable phone adds the image to its favorites. When a user taps the delete control 2622, the foldable phone deletes the image. When a user taps the switch home screen control 2623, the camera app exits the rear-mounted selfie function and enters the folded state's non-selfie mode. The foldable phone displays either photo preview interface 908 or photo preview interface 913 (depending on the user's selected selfie entry method). When a user taps the return control 2624, the foldable phone exits the current image preview interface 2602 and resumes displaying photo preview interface 1106.

[0341] In addition, if the user performs a two-finger zoom operation on the image displayed in the image preview interface 2602, the foldable screen mobile phone will reduce or enlarge the image in response to the user's operation. 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 26 (c). The two-finger zoom operation may include, for example, a two-finger pinch operation.

[0342] In another embodiment, when the foldable screen mobile phone displays the interface shown in Figure 26 (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 2603 (also called the second interface), as shown in Figure 26 (d).

[0343] 9. Folding the phone while taking photos with the front camera unfolded

[0344] In this embodiment, in the unfolded front-facing selfie scenario, the phone is folded directly. The foldable screen phone responds to the user's operation and enters the folded front-facing selfie scenario. Afterwards, the user can access the rear-facing selfie function by clicking the rear-facing selfie control or flipping the phone to wake it up.

[0345] When users take front-facing selfies in the unfolded state, both the main screen and the secondary screen face the user. After users fold their phones, they are generally accustomed to the main screen facing the user. Therefore, after folding the phone and entering the front-facing selfie scene, the main screen lights up, which is more in line with user habits and improves user experience.

[0346] The following is a description with reference to the accompanying drawings.

[0347] For example, Figure 27 is a schematic diagram of the interface changes of a foldable phone when taking a photo with the front camera in the unfolded state, provided by an embodiment of the present application. As shown in Figure 27 (a), the foldable phone is in the unfolded state, and the user is taking a photo with the rear camera. The main screen and the secondary screen jointly display the photo preview interface 2701. The photo preview interface 2701 includes the image captured by the rear camera.

[0348] The photo preview interface 2701 also includes a flip camera control 909. The user clicks the flip camera control 909. In response to the user's operation, the foldable screen phone flips the camera, captures an image through the front camera, and displays the photo preview interface 2501 on both the main screen and the secondary screen, as shown in Figure 27 (b).

[0349] Afterwards, the user folds the phone to the folded state. For example, if the user sets the selfie entry mode to sliding, in response to the user's operation, the secondary screen of the foldable screen phone turns off, and the main screen displays a photo preview interface 1401, which includes the image captured by the front camera, as shown in Figure 27 (c).

[0350] It is understood that if the user sets the selfie entry mode to tile, the flip camera control 909 and the slide indicator arrow 910 in the photo preview interface 1401 are replaced by the second capsule 914 shown in FIG9 and the flip camera control 909 and the rear selfie control 902 displayed tiled in the second capsule 914. No further details are given.

[0351] Based on the photo preview interface 1401, the user can swipe up on the flip camera control 909 to call out the rear selfie control and click to enter the rear selfie function, or click the rear selfie switch to enter the rear selfie function. For details, please refer to the above embodiment and will not be repeated here.

[0352] The above embodiment takes the external folding screen mobile phone as an example to illustrate the method provided by the present application. In some other embodiments, the above method can also be applied to the 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 28 is a structural schematic diagram 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 28, 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 28), and the first structural member 21 and the second structural member 22 are flipped and folded through the connecting assembly 23.

[0353] 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.

[0354] 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.

[0355] 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.

[0356] As shown in Figure (a) in Figure 28, 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.

[0357] When the foldable screen mobile phone 20 is in the unfolded state as shown in Figure 28 (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 28 (a)) to make the foldable screen mobile phone 20 enter the stand state, as shown in Figure 28 (b).

[0358] 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. 28 (c).

[0359] As shown in Figure 28(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 2122.

[0360] 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.

[0361] For example, Figure 29 is a schematic diagram of the interface changes when entering the rear selfie function based on an inward-folding screen mobile phone provided by an embodiment of the present application. As shown in Figure 29 (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 2901. The photo preview interface 2901 includes a rear selfie control 2902.

[0362] The user taps rear-mounted selfie control 2902. In response to the user's action, the foldable phone displays a flip guide interface 2903 via both the first and second inner displays, as shown in FIG29(b). The content of flip guide interface 2903 can be similar to that of flip guide interface 1105, except that the structure of foldable phone schematic 2913 is different.

[0363] After the flip guide interface 2903 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 2904 is displayed through the outer display screen. The photo preview interface 2904 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 2904, as shown in Figure (c) of Figure 29.
