[0001] The present application relates to the field of electronic technology, and in particular to a photographing method and an electronic device. Background Art

[0002] As people's requirements for mobile phone display and portability gradually increase, foldable screen mobile phones are becoming more and more popular among users.

[0003] Folding screen mobile phones include front cameras and rear cameras. Generally, when using folding screen mobile phones to take selfies, you can only use the front camera, and the shooting effect is not good. Summary of the invention

[0004] 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.

[0005] In a first aspect, the present application provides a photographing method, which is performed by an electronic device, wherein the electronic device includes a folding screen, a front camera and a rear camera, the folding screen includes a first screen and a second screen, the front camera and the first screen are on the same side, and the rear camera and the first screen are arranged opposite to each other, 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, and the method includes:

[0006] When the electronic device is in a folded state, the first screen is in a light-on 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 the switching between the front camera and the rear camera; a first operation performed by a 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 lighted, and a second photo preview interface is displayed through the second screen, and the second photo preview interface includes an image acquired through the rear camera.

[0007] The electronic device may be an external folding screen device, such as an external folding screen mobile phone. The first screen is also referred to as a main screen, and the second screen is also referred to as a secondary screen. Optionally, the first screen and the second screen may be two parts of a folding screen.

[0008] The first control is the rear selfie control, and the second control is the flip camera control. Optionally, the layout of the first control and the second control (i.e., the tiled selfie entry mode) can be tiled or sliding. If the layout of the first control and the second control is sliding, the first photo preview interface can be an interface called up by the user sliding. If the first control and the second control can be tiled, the first photo preview interface is an interface that can be directly displayed without user operation.

[0009] Optionally, the first photo preview interface may include an image acquired through the rear camera or an image acquired through the front camera. The second photo preview interface is also a photo preview interface in the rear selfie scene. That is, 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.

[0010] Optionally, the first operation may be an operation of clicking a first control in the first photo preview interface.

[0011] The photographing method provided in the first aspect 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 light-off state. The first photographing preview interface includes a first control, and the user can trigger the rear selfie function by acting on the first operation of the first control, that is, the first screen of the electronic device is off, the second screen is on, and the second photographing preview interface in the rear selfie scene is displayed through the second screen. Since the second screen and the rear camera are on the same side in the folded state, the user can use the rear camera to shoot people or things on the side where the user is (i.e., selfie), and view the first photographing preview interface on the second screen, which is convenient for the user to take selfies. Moreover, the image taken by the rear camera is displayed in the second photographing preview interface, that is, in the rear selfie scene, the image is obtained through the rear camera. The specifications and hardware configuration of the rear camera are relatively high, the image quality captured is relatively high, the shooting effect is relatively good, and the user experience can be improved. On the other hand, the first photo preview interface includes both the first control and the second control, so that the user can 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 scenes and improving the user experience.

[0012] In one possible implementation, displaying a first photo preview interface through a 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 a 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.

[0013] The third photo preview interface does not include the first control.

[0014] Optionally, the second operation may be, for example, a sliding operation on the second control in the third photo preview interface.

[0015] That is, in this implementation, the layout of the first control and the second control is a sliding layout. In the third photo preview interface, the second control is visible and the first control is hidden. The user calls out the first control and displays the first photo preview interface by performing the second operation.

[0016] Optionally, the third photo preview interface may include images acquired through the rear camera, or images acquired through the front camera. In other words, the third photo preview interface may be a preview interface of a rear non-selfie scene in a folded state and a sliding selfie entry mode, or may be a preview interface of a front selfie scene in a folded state and a sliding selfie entry mode.

[0017] 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 requirements, 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, which not only conforms to the user's usage habits, but also has fewer controls, which facilitates the arrangement of controls in the interface and prevents affecting other controls in the user operation interface, thereby further improving the user experience.

[0018] In a possible implementation, the third photo preview interface also 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.

[0019] The operation guide mark may 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 the use method of the control and improve the user experience.

[0020] In a possible implementation, the operation guidance mark is displayed above the second control, and the second operation is a swipe-up operation.

[0021] 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.

[0022] 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 a user on the camera setting control, displaying a camera setting interface through a first screen, the camera setting interface including a first option, the first option being used to set a layout mode of the first control and the second control in the photo preview interface to a first mode or a second mode, the current layout mode being 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.

[0023] The first option is the selfie entry method option. The first method is the sliding method, and the second method is the flat method.

[0024] The fourth photo preview interface is a photo preview interface in which the selfie entry mode is a flat-lay photo preview interface in the folded state. The fourth photo preview interface may include images acquired through the rear camera or images acquired through the front camera.

[0025] Optionally, the third operation may be, for example, an operation of clicking a camera setting control.

[0026] In this implementation, the user can independently switch the selfie entry mode through the camera setting controls as needed, so as to meet the usage requirements of different users, facilitate user operation, and improve user experience.

[0027] 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, a 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 a second option corresponding to the first mode and a 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.

[0028] The second option is the sliding option, and the third option is the tiled option.

[0029] The fourth operation may be, for example, an operation of clicking on the first option. The fifth operation may be, for example, an operation of clicking on the third option. The first pop-up window is a pop-up window for setting the selfie entry mode.

[0030] In this implementation, the state change of the options enables the user to clearly know the currently selected layout mode, thereby improving the user experience.

[0031] 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 includes an image obtained through the rear camera and first guide information, the first guide 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).

[0032] In this implementation, when a user starts a camera application for the first time in the folded state, the electronic device displays a first guide message to guide the user to use the rear-mounted selfie function, thereby facilitating the user's understanding of how to use the rear-mounted selfie function and improving the user experience.

[0033] 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, wherein the fifth photo preview interface includes an image acquired 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.

[0034] The sixth operation may be, for example, clicking on a blank area of ​​the first photo preview interface. The blank area refers to a position in the interface that does not contain controls or guide information.

[0035] 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.

[0036] In one possible implementation, the method also includes: in response to the user performing a seventh operation on the second control in the fifth photo preview interface, displaying a sixth photo preview interface through the first screen, wherein the sixth photo preview interface displays an image acquired through the front camera, a second control, second guide information, and a sliding guide animation.

[0037] The seventh operation may be, for example, clicking the second control in the fifth photo preview interface.

[0038] That is to say, when the camera application first enters the front 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 application is in the front selfie scene, which means that the user is taking a selfie, and the user is more likely to use the rear selfie function. Therefore, in this implementation, when the user first enters the front 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 selfie control), so that the user can understand the rear selfie function and how to enter the rear selfie function, and it is convenient for the user to enter the rear selfie function, thereby making the selfie effect better and improving the user experience.

[0039] In a possible implementation, displaying the first photo preview interface through the first screen includes: in response to the user starting the camera application operation, displaying the first photo preview interface, and displaying the first control and the second control tiled in the first photo preview interface.

[0040] In this implementation, the first control and the second control are displayed tiled in the first photo preview interface, and the user can intuitively see the controls, which is convenient for the user to select rear-camera selfie or front-camera selfie according to usage needs, which is convenient to use and improves the user experience.

[0041] In one possible implementation, the first photo preview interface includes an image acquired through a rear camera, and the method further includes: in response to a user performing an eighth operation on a second control in the first photo preview interface, displaying a seventh photo preview interface, the seventh photo preview interface including an image acquired through a front camera, a first control, a second control, and a third control, and the first control and the second control are displayed tiled in the seventh photo preview interface; in response to a ninth operation on the third control by the user, 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.

[0042] The third control is the rear Selfie switch.

[0043] 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.

[0044] In this implementation, the user can enter the front selfie scene in the folded state through the second control. In the preview interface of the front selfie scene in the folded state and the rear non-selfie scene in the folded state, the layout of the first control and the second control are consistent, also in a tiled style. In this way, it is easy to use and improves the user experience.

[0045] In addition, the seventh photo preview interface also includes a third control, and the user can directly click the third control to enter the rear selfie function, which is convenient for user operation and improves the user experience.

[0046] 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, the first guidance information being used to guide the user to take a selfie using the rear camera.

[0047] The ambient light brightness is less than the preset threshold, which means that the electronic device is in a dark environment.

[0048] 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 a better selfie image, thereby improving the user experience.

[0049] Optionally, the first guidance information may be displayed only when the user has not used the rear selfie function to avoid disturbing the user.

[0050] 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.

[0051] 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.

[0052] Optionally, while the second screen displays the first flip guide interface, the electronic device can shield the touch function of the first screen and the second screen. That is, within a preset time (for example, 3 seconds) after the user performs the first operation, the touch function of the first screen and the second screen is shielded. This can prevent the user from accidentally touching the screen and affecting the entry into the rear selfie function, thereby improving the user experience.

[0053] 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.

[0054] For example, if the user selects the portrait mode in the first photo preview interface, the portrait mode will be used in the second photo preview interface, 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.

[0055] In a possible implementation, the second photo preview interface also includes third guidance information, and the third guidance information is used to guide the user to look at the rear camera.

[0056] The third guiding information is also the eye guiding information.

[0057] 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.

[0058] Optionally, the third guidance information may be displayed only when the user uses the rear-mounted selfie function for the first time to reduce disturbance to the user.

[0059] 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 acquired 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 to increase the screen brightness of the second screen.

[0060] In this implementation, the rear selfie function is enabled while supporting super fill light. When the user uses the rear selfie function, the user can use the fourth control to turn on the super fill light function with one click to make the rear selfie effect better.

[0061] 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 also 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 acquired through the rear camera and the second control.

[0062] Optionally, the fifth control may be, for example, a control for switching the home screen. The sixth control may be a control for exiting the rear selfie camera.

[0063] In this implementation, after the user enters the rear Selfie function, the user can exit the function with one key through the fifth control or the sixth control, which is convenient for the user to operate and use, and improves the user experience. Moreover, when exiting the rear Selfie function, before the control screen switches, the second flipping guide interface is first displayed to guide the user to flip the electronic device, so that the user can know how to exit the rear Selfie function, and improve the user experience.

[0064] 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.

[0065] Optionally, the first function may be a flip wake-up function.

[0066] In this implementation, if the user has not turned on the first function, after the user exits the rear selfie function, the second pop-up window will ask the user whether to turn on the first function. In this way, for users who do not often use the camera setting control and are not familiar with the camera functions, it is convenient for the user to learn about the first function in time and turn on the first function.

[0067] Optionally, the second pop-up window may be displayed after the user uses the rear-camera selfie function for the first time.

[0068] 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 a ninth photo preview interface; in response to the user flipping the electronic device, controlling the first screen to turn off, controlling the second screen to turn on, and displaying the second photo preview interface through the second screen.

[0069] 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 user can quickly and conveniently enter the rear selfie function, thereby improving the intelligence of the electronic device and thus improving the user experience.

[0070] In one possible implementation, in response to a user flipping the electronic device, controlling the first screen to turn off and controlling the second screen to turn on, and after that 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.

[0071] 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 control or the rear-mounted selfie exit control 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.

[0072] 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 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.

[0073] 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. In this way, for users who do not often use the camera setting controls and are not familiar with the camera functions, it is convenient for the user to promptly understand that the layout mode is switchable, and it is convenient for the user to directly switch the layout mode, so as to facilitate the use of the rear selfie function.

[0074] Optionally, the third pop-up window may be displayed after the user uses the rear-mounted selfie function for the second time, so that it can be displayed sequentially with the first pop-up window in the above embodiment to prevent multiple pop-up windows from being displayed to the user at one time, affecting the user experience.

[0075] In one possible implementation, after displaying the third pop-up window through the first screen, the method also 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.

[0076] 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.

[0077] 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.

[0078] In one possible implementation, the method also 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 displaying the tenth photo preview interface through the first screen and the second screen together, the tenth photo preview interface including the image acquired by the front camera.

[0079] The tenth photo preview interface is the interface of the front selfie scene in the expanded state.

[0080] In this implementation, the user unfolds the foldable screen phone to the expanded state while using the rear-mounted selfie function, indicating that the user needs to take a selfie in the expanded state. Therefore, directly entering the expanded state front-mounted shooting scene is likely to meet the user's usage needs and improve the user experience.

[0081] In one possible implementation, an image acquired by a front camera is displayed in a first photo preview interface; and the first photo preview interface is displayed through the first screen, including: when the electronic device is in an unfolded state and a tenth photo preview interface is displayed jointly through the first screen and the second screen, in response to the user folding the electronic device into a folded state, controlling the first screen to light up and controlling the second screen to turn off, and displaying the first photo preview interface through the first screen.

[0082] 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 unfolded state.

[0083] In this implementation, in the unfolded front selfie scene, the phone is folded directly, and the foldable screen phone responds to the user's operation and enters the folded front selfie scene. Afterwards, the user can enter the rear selfie function by clicking the rear selfie control or flipping to wake up.

[0084] In one possible implementation, the method also includes: when the second screen displays a second photo preview interface, in response to the tenth operation performed by the user on the first screen, exiting the camera application to the background; controlling the second screen to turn off, and controlling the first screen to turn on; in response to the eleventh operation performed by the user on the first screen, controlling the camera application to run in the foreground, and displaying the first flip guide interface through the first screen; after the first flip guide interface is displayed for a first preset time, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the second photo preview interface through the second screen.

[0085] The tenth operation is to exit the camera application 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 from the bottom of the screen for a certain distance and pausing, to enter the multitasking interface, and the user clicks on the interface thumbnail of other tasks (applications) in the multitasking interface. The eleventh operation is to make the camera application run again in the foreground, for example, by clicking the camera application icon.

[0086] In this implementation, if the user exits the camera application to the background application, the electronic device can keep the memory of the camera application running, and when the user starts the camera application again, the rear Selfie function continues to run. In this way, the user does not need to repeat the operation to enter the rear Selfie function, which simplifies the user operation and improves the user experience.

[0087] 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.

[0088] The seventh control is a thumbnail of the image taken by the user in the photo preview interface. The first interface is an image preview interface in the folded state.

[0089] In this implementation, when the user uses the rear Selfie function, the captured image can be viewed through the image thumbnail in the second photo preview interface. The image can be displayed on the second screen. In this way, the user can view the image at any time without exiting the rear Selfie function, which is convenient for the user and improves the user experience.

[0090] 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 an unfolded state, controlling the first screen to light up, and displaying the second interface through the first screen and the second screen together, wherein the second interface includes an image corresponding to the thumbnail.

[0091] The second interface is the image preview interface in the expanded state.

[0092] In this implementation, when the rear selfie function is not exited, when the user is viewing an image through the second screen, if the electronic device is unfolded to the unfolded state, the electronic device displays the image through the first screen and the second screen. That is, when viewing an image through the second screen, the user can unfold the folded screen at any time, and display the image through the first screen and the second screen at the same time, that is, support large image preview, facilitate user use, and improve user experience.

[0129] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in the specification of the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0132] Folding screen mobile phones are mainly divided into external folding screen mobile phones and internal folding screen mobile phones. Whether it is an external folding screen mobile phone or an internal folding screen mobile phone, it can include several forms such as folding state, bracket state and unfolded state. Among them, the bracket state refers to the form between the folded state and the unfolded state. Both the external folding screen mobile phone and the internal folding screen mobile phone include a foldable screen. In the unfolded state, the foldable screen is in an unfolded state. When the external folding screen mobile phone is in the unfolded state, when the foldable screen faces the user, the mobile phone is folded to the side away from the user (called outward folding), and the form of the external folding screen mobile phone changes to the bracket state, and continues to fold outward, and the form changes to the folded state. When the internal folding screen is in the unfolded state, when the foldable screen faces the user, the mobile phone is folded to the side close to the user (called inward folding), and the form of the external folding screen mobile phone changes to the bracket state, and continues to fold inward, and the form changes to the folded state.

[0133] The embodiment of the present application mainly takes an external folding screen mobile phone as an example to illustrate the method of taking pictures. For ease of understanding, the structure of the external folding screen mobile phone is first introduced.

[0134] For example, Figure 11 shows the front and back views of the foldable screen mobile phone 10 in the unfolded state, and the foldable screen mobile phone 10 is an external foldable screen mobile phone. Figure 1 As shown, the folding screen mobile phone 10 includes a first structural member 11, a second structural member 12, and a connecting component 13 (located at Figure 1 The first structural member 11 and the second structural member 12 are flipped and folded through the connecting component 13.

[0135] 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 shell 112 and a raised portion 113. The main screen 111 is provided with a front camera 1111. The first back shell 112 and the raised portion 113 are provided at the back of the main screen 111. The raised portion 113 may be provided with a rear camera 1122.

[0136] The second structural member 12 may include a sub-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 disposed at the back of the sub-screen 121.

[0137] During use, the angle between the first structural member 11 and the second structural member 12 is changed by the connecting component 13 to realize various forms of the folding screen mobile phone 10. It can be understood that the secondary screen 121 and the main screen 111 can actually be an integrated flexible display screen (i.e., a foldable screen). When the folding screen mobile phone 10 is folded by the connecting component 13, the connecting component 13 divides the screen into two parts: the main screen 111 and the secondary screen 121, wherein the main screen 111 and the rear camera are located on the same side of the connecting component.

[0138] like Figure 1 As shown, when the angle between the first structural member 11 and the second structural member 12 is approximately 180°, the folding 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 folding screen mobile phone 10 simultaneously displays the content to be displayed through the main screen 111 and the sub-screen 121. Optionally, in the unfolded state, the main screen 111 and the sub-screen 121 can jointly display the interface of the same application, or they can display the interfaces of different applications in split screens.

[0139] In the folding screen mobile phone 10 Figure 1 In the unfolded state shown, when the main screen 111 and the secondary screen 121 are both on, the user can gradually move the foldable screen mobile phone 10 outward ( Figure 1The foldable screen mobile phone 10 is folded in the direction indicated by the arrow in the middle to put it into the support state. Figure 2 shown.

[0140] When the foldable screen mobile phone 10 is in the support state, if the angle between the first structural member 11 and the second structural member 12 is greater than 45°, the main screen and the secondary screen are kept on at the same time. Figure 2 When the angle between the first structural member 11 and the second structural member 12 gradually decreases to about 45°, the secondary screen 121 turns off, and only the main screen 121 is in a bright state, displaying the content to be displayed. In the subsequent folding process, only the main screen 111 is kept bright until the angle between the first structural member 11 and the second structural member 12 is about 0°, as shown in FIG. Figure 3 The folded state is shown.

[0141] like Figure 3 As shown in (a) and (b) of FIG. 1 , when the folding screen mobile phone 10 is in the folded state, the surface of the sub-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 sub-screen 121 and the rear camera 1122 are on the same side. In the folded state, the light emitting direction of the sub-screen 121 is opposite to the light entering direction of the rear camera 1122.

[0142] In the folded state, the foldable screen mobile phone 10 displays the content to be displayed through the main screen 111, and the secondary screen 121 does not display and can be in the off-screen state. It should be noted that when the secondary screen 121 is in the off-screen state, it does not receive touch operations. Therefore, in the folded state, the user performs touch operations through the main screen 111.

[0143] The process of the foldable screen mobile phone 10 gradually unfolding from the folded state to the unfolded state, the state change of the screen, etc. is the reverse process from the unfolded state to the folded state, and will not be repeated here.

[0144] In the above Figures 1 to 3 With the support of the structure of the folding screen mobile phone 10, in the photo shooting scene, when the folding screen mobile phone 10 is in Figure 1 In the unfolded state shown in FIG. 1 , the user can use the rear camera 1122 to shoot people or objects around him, and the shot images can be displayed simultaneously on the main screen 111 and the sub-screen 121, as shown in FIG. Figure 4 As shown in Figure (a) in FIG. 1 , this shooting scene is also called the rear non-selfie scene in the unfolded state. At the same time, when the folding screen mobile phone 10 is in Figure 1 In the unfolded state shown in FIG. 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 FIG. Figure 4 As shown in Figure (b), this shooting scene is also called the front selfie scene in the unfolded state.

[0145] When the foldable screen mobile phone 10 is in Figure 3 In the folded state shown in FIG. 1 , the user can use the rear camera 1122 to take pictures of people or objects around him, and the taken images are displayed on the main screen 111, as shown in FIG. Figure 5 As shown in Figure (a) in FIG. 1 , this shooting scene is also called the rear non-selfie scene in the folded state. Figure 3 In the folded state shown, the user can also use the front camera 1111 to take selfies, and the captured images are displayed on the main screen 111, as shown in FIG. Figure 5 As shown in Figure (b), this shooting scene is also called the front-facing selfie scene in the folded state.

[0146] 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.

[0147] 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, and 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 follows: Figure 5 As shown in Figure (c).

[0148] It is understandable 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 a foldable screen mobile phone. The embodiment of the present application is described by taking a foldable screen mobile phone as an example.

[0149] For example, Figure 6 It is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application.

[0150] The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, 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.

[0151] It is to be understood that the structure illustrated in the embodiment of the present application does 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 in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0152] 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 processor (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), etc. Different processing units may be independent devices or integrated into one or more processors.

[0153] 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.

[0154] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0155] The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which is connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering.

[0156] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. In some embodiments, the electronic device 100 may include 1 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, that is, the electronic device 100 may include 2 display screens 194, one of which is a main screen and the other is a secondary screen. The main screen and the secondary screen may be connected as one and made of a flexible material.

[0157] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0158] ISP is used to process the data fed back by camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to ISP for processing and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, ISP can be set in camera 193.

[0159] 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. Among them, the front camera is arranged on the main screen, and the rear camera is arranged on the raised portion.

[0160] 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 through the external memory interface 120 to implement a data storage function, such as storing music, video and other files in the external memory card.

[0161] The internal memory 121 may be used to store computer executable program codes, which include instructions. The processor 110 executes the instructions stored in the internal memory 121 to perform various functional applications and data processing of the electronic device 100.

[0162] 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 state of the electronic device is a folded state or an unfolded state according to the angle, and then control the states of the main screen and the sub-screen.

[0163] 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 the distance. The electronic device 100 can measure the distance by infrared or laser. In some embodiments, when shooting a scene, the electronic device 100 can use the distance sensor 180F to measure the distance to achieve fast focus.

[0164] In the embodiment of the present application, one or more of the gyro 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.

[0165] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. In the embodiment of the present application, in the front selfie scene, the ambient light sensor 180L can be used to detect the ambient brightness to determine whether to display the rear selfie guide information.

[0166] The touch sensor 180K is also called a "touch panel". The touch sensor 180K can be set on the display screen 194, and 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 acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100, which is different from the position of the display screen 194.

[0167] The hardware system of the electronic device 100 is described in detail above, and the software system of the electronic device 100 is introduced below. The software system can adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the layered architecture as an example to exemplarily describe the software system of the electronic device 100.

[0168] like Figure 7 As shown, the software system using the layered architecture is divided into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the software system can be divided into four layers, from top to bottom, namely, application layer 210, application framework layer 220, hardware abstraction layer 230 and driver layer 240. In addition, for the convenience of explanation, Figure 7 Also shown is a hardware layer 250 of the electronic device.

[0169] The application layer 210 may include camera and gallery applications, and may also include calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0170] The application framework layer 220 provides an application access interface and a programming framework for the application programs of the application layer 210 .

[0171] 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.

[0172] 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.

[0173] The camera device in the application framework layer 220 is used to provide a data access interface between different camera devices and camera management.

[0174] The hardware abstraction layer 230 is used to abstract the 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 the algorithm in the camera algorithm library.

[0175] 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.

[0176] 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 a depth sensor (time of flight, TOF) and a multi-spectral sensor.

[0177] The following is an illustrative description of the workflow of the software system of the electronic device 100 in conjunction with a photo-taking scenario.

[0178] When the user clicks on the touch sensor 180K corresponding to the photo control, the camera APP is awakened by the single click operation and calls various camera devices of the camera hardware abstraction layer through the camera access interface. For example, the camera hardware abstraction layer determines that the current zoom factor is between the zoom factors of [0.6, 0.9], and thus, an instruction to call the wide-angle camera can be sent to the camera device driver, and the camera algorithm library starts to load the preset algorithm.

[0179] When the sensor of the hardware layer is called, for example, sensor 1 in the wide-angle camera is called, sensor 1 obtains the original image and sends the original image to the image signal processing for preliminary processing such as registration. The image after preliminary processing is returned to the hardware abstraction layer through the camera device driver, and then processed using the preset algorithm in the camera algorithm library to obtain the captured image (i.e., photo). The obtained image is sent back to the camera application through the camera hardware abstraction layer and the camera access interface for display and storage.

[0180] It should be noted that the above process describes the workflow of the software system after the user clicks the photo control. In the photo preview scenario, the workflow of the electronic device software system to obtain the image is similar to the above process, except that the user does not click the photo control, so the image does not need to be stored and only needs to be displayed on the photo preview interface.

[0181] In the following, 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.

[0182] To facilitate understanding, several terms involved in the following embodiments are first explained.

[0183] 1. Enable the function

[0184] In the embodiment of the present application, when the folding screen mobile phone has a certain function, turning on the function means turning on the switch of the function so that the folding screen mobile phone can use the function. After turning on a certain function, the function is said to be in the on state, the on state, or the function is turned on. It can be understood that some functions need to be turned on by a switch to be in the on state, such as the smile capture function of the camera application. And 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.

[0185] 2. Turn off the function

[0186] In the embodiment of the present application, when the folding screen mobile phone has a certain function, turning off the function means turning off the switch of the function so that the folding screen mobile phone cannot use the function. After turning off a certain function, the function is said to be in a turned-off state, or the function is said to be turned off.

[0187] 3. Enter the function

[0188] 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.

[0189] 4. Exit function

[0190] In the embodiment of the present application, exiting a certain function means, when the folding screen mobile phone turns on the function, stopping the use of the function through user operation or automatic triggering of the folding screen mobile phone.

[0191] In the implementation of this application, the camera application in the folding screen mobile phone has a rear selfie function. Users can take selfies through the rear camera to improve the quality and effect of the selfie images. The following describes the relevant process according to the use stage of the rear selfie function and the application scenario.

[0192] 1. Selfie entry method

[0193] 1. Introduction to selfie entry method

[0194] 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 mode refers to the display mode (also referred to as the layout mode) of the entrance to the front selfie function and the entrance to the rear selfie function. Therefore, the selfie entrance mode is essentially the display mode of the flip camera control and the rear selfie control.

[0195] Optionally, there may be multiple ways of selfie entrance, for example, a sliding way (also called a first way) and a flat way (also called a second way). They are described below in conjunction with the accompanying drawings.

[0196] For example, Figure 8 1 is a schematic diagram of an interface change using a sliding selfie entrance provided in an embodiment of the present application. Figure 8 As shown in Figure (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 the sliding type, after the camera application is started, the foldable screen mobile phone obtains the image through the rear camera, and displays the photo preview interface 908 through the main screen. The photo preview interface 908 includes the image obtained by the rear camera, and the sliding selfie entry is displayed in the photo preview interface 908. In other words, the photo preview interface 908 is a preview interface of the rear non-selfie scene in the folded state and the sliding selfie entry mode.

[0197] 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 switch 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 with the front camera. For the photo preview interface of the front selfie scene in the folded state, please refer to the subsequent embodiments. Fig.14 Figure (b) in .

[0198] The sliding indicator arrow 910 is used to prompt the user to perform a sliding operation to call out the rear selfie control. In some embodiments, the sliding indicator arrow 910 can be continuously displayed with an animation effect to prompt the user that it can slide here. In other embodiments, the sliding indicator arrow 910 can also be displayed with an animation effect only in a preset scene, and statically displayed in other scenes. 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 sliding indicator arrow 910 is displayed with an animation effect.

[0199] The user can slide in the direction of the slide 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, such as Figure 8 As shown in FIG. (b) in FIG. 9 . 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. Figure 8 Figure (a) to Figure 8 The change process of Figure (b) is similar to expanding the sliding shortcut menu, calling out the hidden rear selfie control 902, so that the flip camera control 909 and the rear selfie control 902 are displayed in the interface at the same time.

[0200] The user can choose to click the rear Selfie control 902 to enter the rear Selfie function according to the 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 the subsequent embodiments.

[0201] 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 a preset time, that is, the user does not operate the first capsule 911 within the preset time, the sliding shortcut menu is retracted, the rear Selfie control 902 is hidden, and the interface is restored to the photo preview interface 908. Figure 8 As shown in Figure (c).

[0202] 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 affecting other controls in the user operation interface, and further improves the user experience.

[0203] For example, Fig. 9FIG. 1 is a schematic diagram of an interface of a flat-lay selfie entry provided in an embodiment of the present application. Fig. 9 As shown, the foldable screen mobile phone is in the folded state, the secondary screen is in the off state, and the selfie entry mode is in the flat-laying mode. After the camera application is started, the foldable screen mobile phone obtains the image through the rear camera, and displays the 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 the flip camera control 909 and the rear selfie control 902 in a flat manner. 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 scene in the folded state.

[0204] In other words, the photo preview interface 913 is a preview interface of the rear non-selfie scene in the folded state and flat selfie entrance.

[0205] 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.

[0206] The above-mentioned photo preview interface 908 and photo preview interface 913 are also collectively referred to as the ninth photo preview interface.

[0207] 2. Switching of selfie entry mode

[0208] 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.

[0209] For example, Fig.10 908. This is a schematic diagram of an interface change for switching the selfie entry mode provided by an embodiment of the present application. Taking the foldable screen mobile phone in the folded state and the current selfie entry mode as the sliding mode as an example, after the camera application is started, the photo preview interface 908 is displayed through the main screen. The photo preview interface 908 includes the image obtained by the rear camera, and the photo preview interface 908 includes a flip camera control 909 and a sliding indicator arrow (also called an operation guide mark) 910, as shown in FIG. Fig.10 As shown in Figure (a).

[0210] The photo preview interface 908 also includes a camera setting control 903. The user clicks the camera setting control 903, and the folding screen mobile phone responds to the user's operation and displays a camera setting interface 904, such as Fig.10As shown in FIG. (b) in FIG. 904, the camera setting interface 904 includes a selfie entry mode option (also referred to as a first option) 905. The current selfie entry mode option 905 is displayed as "sliding type".

[0211] The user clicks on the selfie entry mode option 905, and the foldable screen mobile phone responds to the user's operation and displays a selfie entry mode setting pop-up window (also called a first pop-up window) 906, such as Fig.10 As shown in Figure (c).

[0212] The selfie entry mode setting pop-up window 906 includes a sliding option (also called the second option) 9061, a tile option (also called the third option) 9062, and a confirmation control 9063. Fig.10 As shown in Figure (c), the current sliding option 9061 is in a selected state and is highlighted, and the tiled option 9062 is in an unselected state and is not highlighted.

[0213] The user clicks on the tile option 9062, and the foldable screen mobile phone responds to the user's operation by highlighting the tile option 9062 and non-highlighting the sliding option 9061, as shown in FIG. Fig.10 As shown in Figure (d).

[0214] Afterwards, the user clicks the confirmation control 9063, and the foldable screen mobile phone responds to the user's operation and switches the selfie entry mode to the flat style, the selfie entry mode setting pop-up window 906 is closed, and the foldable screen mobile phone displays the camera setting interface 904. At this time, the selfie entry mode option 905 in the camera setting interface 904 is displayed as "flat style", as shown in FIG. Fig.10 As shown in Figure (e).

[0215] 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 displayed in a tiled manner. Fig.10 As shown in Figure (f) in the figure. Optionally, the return operation can be, for example, a side-slide operation (i.e., sliding inward from the side of the screen), clicking the return key in the three-key navigation bar, or clicking the return control in the interface, etc., and this embodiment of the application does not make any limitation on this. The subsequent embodiments are also the same and will not be repeated here.

[0216] The process of switching the selfie entry mode from flat to sliding is similar to the above process and will not be repeated here.

[0217] 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 methods of the front selfie scene and the rear non-selfie scene in the folded state are synchronized.

[0218] 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.

[0219] 2. Setting the flip wake-up function

[0220] In the 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 lifts 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.

[0221] The following is a brief description of the setting process of the flip wake-up function with reference to the accompanying drawings.

[0222] 1. Enable the flip wake-up function

[0223] For example, Fig.11 This is a schematic diagram of an interface change for setting a flip wake-up function provided in an embodiment of the present application. Fig.11 As shown in Figure (a), when the foldable screen mobile phone is in the folded state, after the camera application is started, the user can Fig.10 The process shown in Figure (a) to Figure (b) in FIG. 1 enters the camera setting interface 904. For the specific process, see Fig.10 The illustrated embodiments will not be described in detail.

[0224] The camera setting interface 904 includes a flip wake up rear selfie option 1001. The user clicks on the option 1001 to enter the flip wake up rear selfie setting interface (referred to as the flip wake up setting interface 1002), such as Fig.11 The flip wake-up setting interface 1002 includes a switch control (referred to as the flip wake-up switch) 1003 for the flip wake-up rear selfie function. The flip wake-up switch 1003 is in the off state by default and is grayed out. When the user clicks the flip wake-up switch 1003, the foldable screen phone responds to the user's operation and turns on the flip wake-up function, and the flip wake-up switch 1003 is highlighted. Fig.11 As shown in Figure (c).

[0225] Afterwards, the user performs two return operations, and the foldable screen mobile phone successively exits the flip wake-up setting interface 1002 and the camera setting interface 904, and restores the photo preview interface 908. Fig.11 As shown in Figure (d).

[0226] 2. Turn off the flip wake function

[0227] The closing process of the flip wake-up function is similar to the above-mentioned opening process, except that the closing process is to switch the flip wake-up switch 1003 from the on state to the off state, which will not be described in detail here.

[0228] In this embodiment, the user can independently set the flip wake-up function to be turned on or off as needed, to meet the user's different usage habits and usage needs in different scenarios, to facilitate user operation, and to improve user experience.

[0229] 3. Entering and exiting the rear selfie function

[0230] When using the camera application, the user 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 sub-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 sub-screen. The photo preview interface 1106 includes the image obtained by the rear camera. In other words, the photo preview interface 1106 is a photo preview interface in the rear selfie scene, that is, a 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, in the process of using the rear selfie function, the user can perform selfie-related operations through the sub-screen, which is convenient to use and further improves the user experience.

[0231] After entering the rear selfie function, the user can also exit the rear selfie function through corresponding operations. After exiting the rear selfie function, the camera application enters the rear non-selfie scene in the folded state, the folding screen phone turns off the secondary screen, and displays the corresponding photo preview interface on the main screen, as described above. Figure 8 Figure (a) or Fig. 9 That is to say, after entering the rear selfie function, the user can exit the function at any time, which is convenient for user operation and use and improves the user experience.

[0232] In the embodiments of the present application, several methods of entering and exiting the rear-camera selfie function are provided, which are described below respectively.

[0233] 1. Enter and exit the rear selfie function through the control

[0234] For example, Fig.12 1 is a schematic diagram of an interface change for entering the rear selfie function provided in an embodiment of the present application. Fig.12As shown in (a) of FIG. 1 , 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, and the main screen is in the on state. Taking the selfie entry mode selected by the user as the flat style as an example, the main screen displays the photo preview interface 913.

[0235] It should be noted that, in general, when the main screen is on and the secondary screen is off, the user will turn the main screen of the foldable phone toward the user and the secondary screen (i.e., the side where the rear camera is) toward the user. The embodiments of this application are described using this as an example to facilitate description of the situation before and after the user flips the foldable phone.

[0236] User clicks Fig.12 In the rear selfie control 902 in the middle (a) figure, in response to the user's operation, the folding screen mobile phone displays a flip guide interface 1105 (also called a first flip guide interface) through the main screen, such as Fig.12 As shown in Figure (b) in the figure. The flip guide interface 1105 is used to guide the user to flip the folding 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 guide interface 1105 may include text prompt information 1151, an arrow 1152 indicating the flip direction, and a schematic diagram 1153 of a folding screen mobile phone. Optionally, the flip guide interface 1105 may continuously display multiple schematic diagrams 1153 of a folding screen mobile phone at different angles to present a dynamic picture of flipping the mobile phone, so as to more clearly guide the user to flip the mobile phone and improve the user experience. Optionally, the text reminder message 1151 may be, for example, "Please flip the phone and use the rear camera for selfie."

[0237] Optionally, in the 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., shielded), that is, the screen does not respond to the user's touch operation. In this way, it 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.

[0238] After the flipping 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 sub-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 sub-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 sub-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 through the rear camera can be displayed in the photo preview interface 1106, such as Fig.12 As shown in Figure (c).

[0239] 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, and obtain an image through the rear camera, and display the photo preview interface 1106 through the secondary screen. In other words, after the user clicks the rear selfie control, the main screen displays the flip guide interface 1105 and the secondary screen lights up at the same time, and the photo preview interface 1106 is displayed through the secondary screen.

[0240] 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, within a preset time (for example, 3 seconds) after the user clicks the rear selfie control 902, the touch functions of the main screen and the secondary screen are blocked. This can prevent users from accidentally touching the screen and improve the user experience.

[0241] The photo preview interface 1106 includes a photo control 1107. When the user clicks the photo control 1107, the camera application saves the image acquired by the rear camera.

[0242] Optionally, the shooting modes supported by the rear Selfie function may include photo mode, video mode, portrait mode, night scene mode, etc. As a possible implementation, after the user enters the rear Selfie function through the above process, the default shooting mode is consistent with the shooting mode before entering the rear self-timer function, that is, the shooting mode in the photo preview interface 1106 is consistent with the shooting mode in the photo preview interface 913. In this way, the user's choice can be inherited and the user experience can be improved. Of course, after entering the rear Selfie function, the user can also switch the shooting mode to other modes as needed.

[0243] For example, Fig.13 This is a schematic diagram of an example of interface changes for exiting the rear selfie function provided in an embodiment of the present application. Fig.12 As shown in Figure (c) Fig.13 As shown in FIG. 1 (a), the photo preview interface 1106 includes a switch home screen control (also called the fifth control) 1108 and a rear selfie exit control (also called the sixth control) 1109. The user clicks the switch home screen control 1108 or the rear selfie exit control 1109. In response to the user's operation, the folding screen mobile phone displays a flip guide interface 1301 (also called a second flip guide interface) through the secondary screen, as shown in FIG. Fig.13As shown in Figure (b) in the figure. The flip guide interface 1301 is used to guide the user to flip the folding screen mobile phone so that the side where the main screen is located faces the user, and the side where the secondary screen is located (i.e., the side where the rear camera is located) faces away from the user. Optionally, the flip guide interface 1301 may include text prompt information 1311, an arrow 1312 indicating the flipping direction, and a schematic diagram 1313 of the folding screen mobile phone. Optionally, multiple schematic diagrams of folding screen mobile phones at different angles can be displayed continuously to present a dynamic picture of flipping the mobile phone in the flip guide interface 1301, so as to more clearly guide the user to flip the mobile phone and improve the user experience. Optionally, in this interface, the text reminder message 1311 can be, for example, "The rear selfie has exited, please flip the phone."

[0244] After the flipping guide interface 1301 is displayed for a preset time, the camera application exits the rear selfie function. Specifically, the folding screen mobile phone turns off the secondary screen and controls the main screen to light up. At the same time, the image is acquired through the rear camera, and the photo preview interface 913 is displayed through the main screen. The photo preview interface 908 includes the image acquired 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 acquired by the rear camera, such as Fig.13 As shown in Figure (c).

[0245] In this implementation, when the user is 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.

[0246] In another embodiment, in the front selfie scene, the user can enter the rear selfie function through the rear selfie switch (also called the permanent rear selfie control or the third control). Specifically, when the camera application is in the front selfie scene, the photo preview interface may further include a rear selfie switch. The rear selfie switch can be used to control the activation of the rear selfie function. The following is an explanation with reference to the accompanying drawings.

[0247] For example, Fig.14 This is a schematic diagram of an example of interface changes during the process of entering the rear Selfie function through the rear Selfie switch provided in an embodiment of the present application. Fig.14 As shown in FIG. 9( a ), taking the sliding selfie entry mode as an example, the folding screen mobile phone is in a folded state, the main screen is in a light state, the secondary screen is in a light-off state, the camera application is started, and the main screen displays a photo preview interface 908. The photo preview interface 908 includes an image obtained by the rear camera.

[0248] The photo preview interface 908 includes a flip camera control 909. The user clicks the flip camera control 909. In response to the user's operation, the front selfie scene in the folded state is entered, and a photo preview interface 1401 (also called the seventh photo preview interface) is displayed. The photo preview interface 1401 includes an image obtained by the front camera, the flip camera control 909 and a sliding indication arrow 910, as shown in FIG. Fig.14 In addition, the photo preview interface 1401 also includes a rear Selfie switch (also called a third control) 1402.

[0249] 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, such as Fig.14 As shown in Figure (c).

[0250] After the flip guide interface 1105 is displayed for a preset time, 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 obtained through the rear camera, and the photo preview interface 1106 is displayed on the secondary screen. The photo preview interface 1106 includes the image obtained by the rear camera, such as Fig.14 As shown in Figure (d).

[0251] In this embodiment, in the front-mounted selfie scenario, the interface includes a rear-mounted selfie switch, and the user can directly click the rear-mounted selfie switch to enter the rear-mounted selfie function, which is convenient for user operation and improves user experience.

[0252] 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.

[0253] 2. Flip the phone to wake up or exit the rear selfie function

[0254] As mentioned above, the camera application of the foldable screen mobile phone can have a flip wake-up function. When the flip wake-up function is turned on (the turning-on process refers to Fig.11 ), the folding 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 the rear selfie control or exiting the rear selfie control 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.

[0255] For example, Fig.15 This is a schematic diagram of an example of interface changes for entering and exiting the rear selfie through the flip wake-up function provided in an embodiment of the present application. Fig.15As shown in Figure (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, and the main screen is in the on state. When the foldable 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 foldable screen mobile phone is facing the user, and the side where the secondary screen is facing away from the user.

[0256] If the user wants to use the rear selfie function, the user can lift the foldable screen phone according to the flip wake-up requirement, so that the main screen of the foldable screen phone faces the face and the user looks at the screen, and 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. In this process, the foldable screen phone recognizes the face through the front camera and detects through the sensor that the user flips the phone, and then recognizes the face through the rear camera, the camera application directly 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, such as Fig.15 As shown in Figure (b).

[0257] When the user wants to exit the rear selfie function, the user can reverse the above process, lift the foldable screen phone, make the secondary screen of the foldable screen phone face the face and look at the screen, then flip the foldable screen phone so that the main screen is facing the user and the secondary screen is facing away from the user. The foldable screen phone recognizes the face through the rear camera, detects that the user flips the phone, and recognizes the face through the front camera, then directly exits the rear selfie function, the secondary screen turns off, the main screen turns on, and the photo preview interface 913 is displayed on the main screen, as shown in FIG. Fig.15 As shown in Figure (c).

[0258] 4. Function usage guide

[0259] 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 use guidance of the rear Selfie function and its related functions in combination with the usage scenarios.

[0260] 1. Usage guidance when using the camera app for the first time in folded state

[0261] When a user launches the camera application of a foldable screen mobile phone in the folded state for the first time, the foldable screen mobile 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.

[0262] For example, Fig.16 This is a schematic diagram of an interface for using the camera application for the first time in a folded state provided by an embodiment of the present application. Take the sliding selfie entry mode of a foldable screen mobile phone as an example. Fig.16 As shown in Figure (a), when the foldable screen mobile phone is in the folded state, the secondary screen of the foldable screen mobile phone is in the off state, the main screen is in the on state, and the main screen displays the main interface 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 FIG. Fig.16 Unlike the above-mentioned photo preview interface 908, in the photo preview interface 1603, when the user does not perform an upward sliding operation at the flip camera control 909, the flip camera control 909 and the rear selfie control 902 are directly displayed in the first capsule 911, which is different from the above-mentioned photo preview interface 908. Figure 8 At the same time, the guidance information of the rear Selfie function (referred to as the rear Selfie guidance information, also referred to as the first guidance information) 1604 is displayed at the rear self-timer control 902. The rear self-timer guidance information 1604 is used to guide the user to use the rear Selfie function, so that the user can understand the use method of the rear Selfie function and improve the user experience.

[0263] Optionally, the rear Selfie guidance information 1604 may be displayed in the form of bubbles, cards, capsules, etc. The rear Selfie guidance information 1604 may include prompt text or prompt pictures for introducing the rear Selfie function. Fig.16 In the figure (b), the rear selfie guidance information 1604 may include a prompt picture (a person selfie picture) and prompt text such as "Use the rear selfie super-sensitive portrait lens to take better portrait effects".

[0264] 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.

[0265] It can be understood that when the user uses the camera in the folded state for a non-first time (second time and every time thereafter), the rear Selfie guide information 1604 may no longer be displayed, and the above-mentioned Figure 8 Figure (a) or Fig. 9 The interface shown is used to prevent the user from being disturbed and further improve the user experience. The same is true for other guidance information or prompt information described in subsequent embodiments. They can be displayed for a preset number of times and then no longer displayed, or after the user has used the function used in the guidance, they can no longer be displayed, etc., which will not be repeated in subsequent embodiments.

[0266] Please continue to see Fig.16 .like Fig.16As shown in FIG. 16( b), when the user clicks on a blank area (a location without controls or guide information) in the photo preview interface 1603, the above-mentioned rear selfie guide information 1604 disappears, and a sliding guide animation (also called sliding guide animation) 1605 is displayed, and the use guide information of the sliding selfie entrance (simply referred to as sliding guide information, also called second guide information) 1606 is displayed. Fig.16 As shown in Figures (c) and (d) of the photo preview interface 1607 (also called the fifth photo preview interface).

[0267] The upward sliding guiding animation 1605 is an animation effect of sliding upward from the flip camera control 909, simulating the process of the user sliding upward to trigger the call of the rear selfie control. The upward sliding guiding animation 1605 and the sliding guiding information 1606 are both used to guide the user to understand how to use the user's upward sliding selfie entrance to improve the user experience.

[0268] Optionally, the sliding guidance information 1606 may be displayed in the form of bubbles, cards, capsules, etc. The sliding guidance information 1606 may include prompt text for introducing how to use the sliding up selfie entrance. Fig.16 In Figures (c) and (d), the sliding guidance information 1606 may include prompt text such as "Slide to use the "rear selfie"".

[0269] 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 display Figure 8 The photo preview interface 908 is shown in FIG.

[0270] If the user refers to the upward sliding guidance effect 1605 and performs an upward sliding operation, the upward sliding guidance effect 1605 and the sliding guidance information 1606 disappear, and the rear selfie control is called out, and the following is displayed: Figure 8 The photo preview interface 912 is shown in FIG.

[0271] 2. User guidance when using the front selfie function for the first time in folded state

[0272] 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.

[0273] For example, Fig.17 This is a schematic diagram of the interface changes of using the front selfie function in the folded state for the first time provided by the embodiment of the present application. Fig.17 As shown in FIG. 9( a ), the foldable screen mobile phone is in a folded state, the main screen is in a light-on state, the secondary screen is in a light-off state, the camera application is started, and the main screen displays a photo preview interface 908. The photo preview interface 908 includes an image obtained by the rear camera.

[0274] The photo preview interface 908 also includes a flip camera control 909, and the user clicks the flip camera control 909. This operation is the first time to enter the front selfie function in the folded state. Fig.17 As shown in (b) and (c) of FIG. 1 , 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, and displays the photo preview interface 1701 (also called the sixth photo preview interface), which includes the image obtained by the front camera. Fig.14 The difference between the photo preview interface 1401 shown in FIG. 7 (b) and the photo preview interface 1701 is that the upward sliding guidance effect 1605 and the sliding guidance information 1606 are displayed in the photo preview interface 1701 .

[0275] 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 display Fig.14 The photo preview interface 1401 is shown in FIG.

[0276] If the user refers to the upward sliding guidance effect 1605 and performs an upward sliding operation, the upward sliding guidance effect 1605 and the sliding guidance information 1606 disappear, and the rear selfie control is called out, and the following is displayed: Fig.17 The photo preview interface 1702 shown in FIG. (d) in FIG. The photo preview interface 1702 includes a first capsule 911. The first capsule 911 includes a rear selfie control 902 and a flip camera control 909. The user can choose to click the rear selfie control 902 to enter the rear selfie function according to the needs; or click the flip camera control 909 to return to the rear non-selfie scene in the folded state and redisplay Fig.17 The photo preview interface 908 is shown in FIG.

[0277] When a user uses the front selfie function, it means that the user is taking a selfie, and the probability of using the rear selfie function is relatively high. Therefore, in this implementation, when the user uses the front selfie function for the first time, the user is guided to swipe up to call out the rear selfie control, so that the user can understand the rear selfie function and how to enter the rear selfie function, and it is convenient for the user to enter the rear selfie function, thereby making the selfie effect better and improving the user experience.

[0278] In other embodiments, the above-mentioned sliding up guiding animation 1605 and sliding guiding information 1606 may also be displayed when the user switches the shooting mode, for example, the user switches the shooting mode from the photo mode to the portrait mode, etc. In this case, the user is more likely to use the rear selfie function, so the user is guided to slide up to call out the rear selfie control, so that the user can understand the rear selfie function and the method of entering the rear selfie function, thereby improving the user experience.

[0279] 3. User guidance after switching to the selfie entry method for the first time

[0280] 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.

[0281] For example, Fig.18 This is a schematic diagram of a user guidance interface after switching to the selfie entry mode for the first time provided in an embodiment of the present application. Fig.10 ,like Fig.10 The process shown in Figures (a) to (e) is the first time that the user switches the selfie entry mode to the flat style. Fig.10 In the interface shown in Figure (e) of FIG. 1 , a return operation is performed, and the foldable screen mobile phone responds to the user's operation and displays the following Fig.18 The photo preview interface 1801 shown in FIG. The photo preview interface 1801 includes an image captured by the rear camera. Fig.10 The difference between the photo preview interface 913 shown in Figure (f) is that the photo preview interface 1801 includes the rear selfie guide information 1604.

[0282] If the user clicks on a blank area of ​​the photo preview interface 1801, the rear selfie guide information 1604 disappears and the display Fig.10 The photo preview interface 913 is shown in FIG.

[0283] If the user clicks the flip camera control 909 in the photo preview interface 1801, the front selfie scene is entered and the display Fig.14 The photo preview interface 1401 is shown in FIG.

[0284] If the user clicks the rear Selfie control 902 in the photo preview interface 1801, the rear Selfie function is entered. For the specific process, see the above Fig.12 , no more details.

[0285] 4. Guidelines for using the front camera in dark environments

[0286] In one embodiment, if the user has not used the rear-camera selfie function and is currently in a front-camera selfie scene, when it is detected that the ambient light is dark, the user can be guided to use the rear-camera selfie function.

[0287] For example, Fig.19 This is a schematic diagram of a user guide interface for front-facing selfie in dark environment provided by an embodiment of the present application. Fig.19As shown, the folding screen mobile phone is in a folded state, the main screen is in a bright screen state, the secondary screen is in an off screen state, the camera application is started, and is in a front selfie scene, and the main screen displays a photo preview interface 1901. The photo preview interface 1901 includes an image obtained by the front camera.

[0288] Currently, the user has not used the rear selfie function. Moreover, the folding screen mobile phone detects that it is currently in a dark environment, so the photo preview interface 1901 also includes a rear selfie prompt message 1902. Optionally, the rear selfie prompt message 1902 can be displayed at the rear selfie switch 1402. Optionally, the rear selfie prompt message 1902 can be displayed in the form of a bubble or the like for a preset duration. The content of the rear selfie prompt message 1902 can be, for example, "Use the rear super-sensitive lens to take a selfie for better results".

[0289] If the user clicks on a blank area of ​​the photo preview interface 1901, the rear Selfie prompt message 1902 disappears and the following is displayed: Fig.14 The photo preview interface 1401 is shown in FIG.

[0290] If the user refers to the rear Selfie prompt information 1902 and clicks the rear Selfie switch 1402, the rear Selfie function is entered. For the specific process, see Fig.14 Figures (b) to (d) in the figure are not repeated here.

[0291] 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, and the user is guided to take better selfie images through the rear-facing selfie function, thereby improving the user experience.

[0292] 5. Eye guidance when using the rear selfie function for the first time

[0293] When the user uses the rear-camera 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 so that the image effect obtained by the rear selfie is better.

[0294] For example, Fig. 20 This is a schematic diagram of an eye guidance interface provided in an embodiment of the present application. Fig. 20 As shown, the foldable screen mobile phone enters the rear selfie function for the first time, the main screen is off, the secondary screen is on, and the secondary screen displays the photo preview interface 2001. The photo preview interface 2001 includes the image taken by the rear camera. Fig.12The difference between the photo preview interface 1106 in (c) of FIG. 1 and FIG. 2 is that 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, and take a more natural selfie".

[0295] 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.

[0296] 6. After exiting the rear selfie function, ask whether to turn on the flip wake-up function

[0297] In one embodiment, if the user has not turned on the flip wake-up function, after the user uses the rear Selfie function for the first time and exits, the user is asked whether to turn on the flip wake-up function. In this way, for users who do not often use the camera setting controls and are not familiar with the camera functions, it is convenient for the user to understand the flip wake-up function in time, and convenient for the user to turn on the flip wake-up function, so as to facilitate the user to use the rear Selfie function. Turning on the flip wake-up function means: before the current moment, the user turned on the flip wake-up function and then turned off the flip wake-up function; or before the current moment, the user turned on the flip wake-up function and did not turn off the flip wake-up function afterwards.

[0298] For example, Fig.21 This is a schematic diagram of an interface for asking whether to turn on the flip wake-up function provided in an embodiment of the present application. Fig.13 , the user uses the rear selfie function for the first time and follows Fig.13 After exiting the rear Selfie function, the display shows Fig.13 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 2101 asking whether to turn on the flip wake-up function (referred to as the flip wake-up inquiry window, also referred to as the second pop-up window), and displays the following Fig.21 Interface 2102 is shown.

[0299] 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 .

[0300] If the user clicks on the start control 2106, the foldable screen mobile phone responds to the user's operation, closes the flip wake-up inquiry window 2101, and turns on the flip wake-up function. After that, the user can enter or exit the rear selfie function by flipping the phone. For details, see Fig.15 The process shown will not be repeated here.

[0301] It can be understood that after the user clicks on the start control 2106, the flip wake-up switch 1003 in the flip wake-up rear selfie interface 1002 will be in the on state and highlighted, such as Fig.11 As shown in Figure (c).

[0302] If the user does not check the option 2104 not to prompt again, 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 according to the preset pop-up logic after the subsequent user exits the rear selfie function. 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 up to 3 times, etc. Of course, the prerequisite for each pop-up flip wake-up inquiry window 2101 includes: the user has not checked the option 2104 not to prompt again, 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 flip wake-up inquiry window 2101 is after exiting the rear selfie function.

[0303] If the user checks the "no more prompt" 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 enable the flip wake-up function, and the flip wake-up inquiry window 2101 will no longer pop up subsequently.

[0304] 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, see Fig.11 , no more details.

[0305] 7. After exiting the rear selfie function, the user is prompted to switch to the selfie entry mode

[0306] In one embodiment, if the user has not switched the selfie entry mode, after the user uses the rear selfie function for the second time and exits, the user is guided to switch the selfie entry mode. In this way, for users who do not often use the camera setting controls and are not familiar with the camera functions, it is convenient for the user to promptly understand that the selfie entry mode is switchable, and it is convenient for the user to directly switch the selfie entry mode, so as to facilitate the use of the rear selfie function. Moreover, in this embodiment, after the user uses the rear selfie function for the second time, the user is guided to switch the selfie entry mode, which can be carried out in sequence with the inquiry of the flip wake-up function in the above embodiment, so as to prevent multiple functions from being recommended to the user at one time and affecting the user experience.

[0307] For example, Fig. 22This is a schematic diagram of an interface for guiding the switching of selfie entry modes provided in an embodiment of the present application. Fig.13 , after the user uses the rear selfie function for the second time, Fig.13 After exiting the rear Selfie function, the display shows Fig.13 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 referred to as the third pop-up window) 2201 to guide the user to switch the selfie entry mode, and displays the following Fig. 22 Interface 2202 shown in Figure (a).

[0308] With the above Fig.10 Similar to the selfie entry mode setting pop-up window 906 shown in FIG. (c), the entry guide pop-up window 2201 also includes a sliding option 9061, a tile option 9062, and a confirmation control 9063. Different from the selfie entry mode setting pop-up window 906, the entry guide pop-up window 2201 includes a modification position reminder message 2203 and a no longer prompt option 2204. The modification position reminder message 2203 reminds the user that the selfie entry mode can be modified in the camera settings.

[0309] If the user clicks on the tile option 9062, the tile option 9062 is highlighted and the sliding option 9061 is not highlighted. Fig. 22 As shown in Figure (b) of the figure. After that, the user clicks the confirmation control 9063, and the folding screen mobile phone responds to the user's operation, closes the entry guidance pop-up window 2201, and switches the selfie entry mode to the flat style. At the same time, the rear selfie guidance information 1604 is displayed in the interface, that is, the following is displayed Fig. 22 The photo preview interface 1801 shown in FIG. (c) in FIG. 1802 is shown in FIG. 1804. It can be understood that after the above operation, the selfie entry mode option 905 in the camera setting interface 904 is displayed in a tiled manner, such as Fig. 22 As shown in Figure (d).

[0310] 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.

[0311] 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 more prompt option 2204, and directly clicks the confirmation control 9063, the foldable screen mobile phone responds to the user's operation, closes the entry guidance pop-up window 2201, and the selfie entry method remains unchanged, still maintaining the sliding type, and the interface returns to Fig.13 The photo preview interface 913 is shown in FIG.

[0312] Optionally, in this case, the folding screen mobile phone can also follow the preset pop-up logic, and the entry guide pop-up window 2201 will pop up again after the user 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 up to 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 option 2204 not to prompt again, and the user has not switched the selfie entry mode (whether it is switched in the camera settings or switched through the entry guide pop-up window 2201). Each time the entry guide pop-up window 2201 pops up, it is after exiting the rear selfie function.

[0313] 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 guidance pop-up window 2201, the selfie entry method remains unchanged, and remains in the sliding type, and the entry guidance pop-up window 2201 will no longer pop up subsequently.

[0314] After the user switches the selfie entry mode to the flat style through the above 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 Fig.10 , no more details.

[0315] 5. Super strong fill light when using the rear selfie function

[0316] In the embodiment of the present application, the rear Selfie function is enabled while supporting super fill light. When the user uses the rear Selfie function, the super fill light function can be turned on with one key, making the rear Selfie effect better and further improving the user experience. The following is an explanation with reference to the accompanying drawings.

[0317] For example, Fig.23 This is a schematic diagram of an interface change using super strong fill light provided in an embodiment of the present application. Fig.23 As shown in FIG. 1104 (a), the foldable screen mobile phone is in a folded state, and the rear selfie function is enabled, the main screen is off, the secondary screen is on, and the image captured by the rear camera is displayed on the secondary screen. That is, the secondary screen displays a photo preview interface 1106.

[0318] The photo preview interface 1106 includes a flash option 2301. The user clicks the flash option 2301, and the foldable screen mobile phone responds to the user's operation by expanding the flash option to display an automatic flash 2302, a flash off control 2303, a flash always on switch 2304, and a super fill light switch (also called a fourth control) 2305. Fig.23(b) The photo preview interface 2306 in Figure (b) (also called the eighth photo preview interface). The automatic flash 2302 is used to turn on the flash automatic mode. After turning on this mode, the flash automatically turns on according to the surrounding lighting conditions. The flash off control 2303 is used to turn off the flash. After turning off the flash, the flash does not work. The flash always-on switch 2304 is used to control the flash to always be on (that is, the screen fill light is always on) to perform fill light shooting. The 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.

[0319] The user clicks the super fill light switch 2305, and the folding screen mobile phone responds to the user's operation and turns on the super fill light function. The flash of the rear camera is always on, and the brightness of the secondary screen is increased (shown as grid filling in the figure). At the same time, the secondary screen displays as follows Fig.23 The photo preview interface 2307 shown in FIG. (c) in FIG. The photo preview interface 2307 includes a 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 turned on prompt information 2308.

[0320] If the user needs to turn off the super fill light function, the user can click the super fill light switch 2305 in the photo preview interface 2307. The folding screen mobile phone responds to the user's operation and displays the photo preview interface 2306, such as Fig.23 (d) in FIG. The photo preview interface 2306 and Fig.23 The same as Figure (b) in the figure, the difference is that Fig.23 In Figure (d), the super fill light function is turned on, so the flash of the rear camera is always on and the brightness of the secondary screen is high.

[0321] Then the user clicks the flash off control 2303 in the photo preview interface 2306, and the super fill light function is turned off. The photo preview interface 2309 is displayed, such as Fig.23 The photo preview interface includes a flash off prompt message 2310, which is used to prompt the user that the flash has been turned off.

[0322] 6. After entering the rear selfie function, exit the camera application and go to the background

[0323] After the user enters the rear Selfie function through the control, if the user exits the camera application to the background application, the foldable screen mobile phone can keep the memory of the camera application running within a preset time (for example, 15 minutes), that is, when the user starts the camera application again within the preset time, the rear Selfie function continues to run. In this way, for the user, there is no need to repeat the operation to enter the rear Selfie function, which simplifies the user operation and improves the user experience.

[0324] For example, Fig.24 This is a schematic diagram of the interface changes of an example of entering the rear Selfie function and exiting the camera application in an embodiment of the present application. Fig.24 As shown in Figure (a), the current camera application has entered the rear selfie function, and the photo preview interface 1106 is displayed through the secondary screen. Afterwards, the user executes 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 folding screen mobile phone exits the camera application to the background and displays the main interface (also called the desktop, main page, etc.). b. Slide 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 folding 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 limitation on the operation of exiting the camera to the background.

[0325] The user clicks the Home button in the three-button navigation bar ( Fig.24 (not shown) as an example, 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, such as Fig.24 As shown in Figure (b).

[0326] After the user performs some other operations on the main screen, he clicks the camera application icon 1602 in the main interface 1601 again within a preset time (e.g., 15 minutes). In response to the user's operation, the foldable screen mobile phone starts the camera application and directly enters the rear selfie function, displaying the flip guide interface 1105, such as Fig.24 After the flipping guide interface 1105 is displayed for a preset time, the camera application enters the rear selfie function, the folding screen mobile phone controls the main screen to turn off, the secondary screen to light up, and displays the photo preview interface 1106 on the secondary screen, as shown in FIG. Fig.24 As shown in FIG. 5( d ) , the photo preview interface 1106 includes an image captured by the rear camera.

[0327] In other embodiments, after entering the rear 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 selfie function. Then the user clicks the lock screen button again to light up the screen, and the camera application automatically enters the rear non-selfie scene and displays Figure 8 The photo preview interface 908 shown in FIG. (a) or Fig. 9 The photo preview interface 913 shown depends specifically on the selfie entry mode set by the user. Optionally, the mode after entering the rear non-selfie scene can inherit the shooting mode in the front and rear selfie scenes before the user locks the screen, thereby improving the user experience.

[0328] 7. Unfolding the phone while using the rear-camera selfie function

[0329] In this embodiment, during the use of the rear-mounted selfie function, if the user unfolds the folding 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 folding 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, and the photo preview interface 2501 includes the image obtained by the front camera. In other words, the photo preview interface 2501 is a photo preview interface in the unfolded front-mounted selfie scene. When using the rear-mounted selfie function, the user unfolds the folding screen mobile phone to the unfolded state, indicating that the user needs to take a selfie in the unfolded state, so directly entering the unfolded front-mounted shooting scene is likely to meet the user's usage needs and improve the user experience.

[0330] For example, Fig.25 This is a schematic diagram of the interface changes of a mobile phone during the use of the rear Selfie function provided in an embodiment of the present application. Fig.25 As shown in Figure (a), the user is using the rear selfie function, and the foldable screen mobile phone displays a photo preview interface 1106 through the secondary screen, and the photo preview interface 1106 includes an image obtained by the rear camera. At this time, the side where the secondary screen of the foldable screen mobile phone is located (that is, the side where the rear camera is located) faces the user, and the side where the main screen is located is facing away from the user.

[0331] The user unfolds the foldable screen mobile phone and switches the foldable screen mobile phone to the unfolded state. In this way, the main screen and the secondary screen of the foldable screen mobile phone are facing the user, and the first back shell, the second back shell and the rear camera are facing away from the user. In response to the user's operation, the foldable screen mobile phone obtains an image through the front camera, and at the same time, the secondary screen lights up, and the main screen and the secondary screen jointly display the photo preview interface 2501, which includes the image obtained by the front camera, such as Fig.25 As shown in Figure (b).

[0332] Optionally, after the user unfolds the foldable screen mobile phone through the above process and the foldable screen mobile phone enters the unfolded state front selfie scene, the shooting mode can be consistent with the shooting mode when the rear selfie function is used, that is, the shooting mode in the photo preview interface 2501 is consistent with the shooting mode in the photo preview interface 1106. In this way, the user's choice can be inherited and the user experience can be improved.

[0333] 8. Viewing images while using the rear Selfie function

[0334] In this embodiment, when the user uses the rear Selfie function, the user can view the captured image through the image thumbnail (also referred to as the seventh control) in the photo preview interface 1106. The image can be displayed on the secondary screen, and supports functions such as collection, deletion, and zoom display. In this way, the user can view the image at any time without exiting the rear Selfie function, which is convenient for the user and improves the user experience.

[0335] In addition, when the user is viewing an image, if the foldable screen phone is unfolded, the foldable screen phone will display the image through both the main screen and the secondary screen, and support functions such as sharing, collecting, editing, and deleting. In other words, when viewing an image through the secondary screen, the user can unfold the foldable screen at any time and display the image through the main screen and the secondary screen at the same time, that is, support large image preview, which is convenient for users to use and improves the user experience.

[0336] The following is a description with reference to the accompanying drawings.

[0337] For example, Fig.26 This is a schematic diagram of an example of an interface change for viewing an image during the use of the rear Selfie function provided in an embodiment of the present application. Fig.26 As shown in FIG. 1 (a), the user is using the rear selfie function, and the foldable screen mobile phone displays a photo preview interface 1106 through the secondary screen. The photo preview interface 1106 includes a thumbnail 2601 of the image taken by the user.

[0338] The user clicks on thumbnail 2601, and the foldable screen mobile phone responds to the user's operation by displaying an image preview interface 2602 (also called a first interface) through the secondary screen. The image preview interface 2602 includes an image corresponding to thumbnail 2601, such as Fig.26 As shown in (b) of the figure. In addition, the image preview interface 2602 includes a collection control 2621, a delete control 2622, a switch home screen control 2623 and a return control 2624. The user clicks the collection control 2621, and the foldable screen mobile phone collects the image. The user clicks the delete control 2622, and the foldable screen mobile phone deletes the image. The user clicks the switch home screen control 2623, the camera application will exit the rear selfie function, enter the rear non-selfie scene in the folded state, and the foldable screen mobile phone will display the photo preview interface 908 or the photo preview interface 913 (depending on the selfie entry method set by the user). The user clicks the return control 2624, the foldable screen mobile phone will exit the current image preview interface 2602, and restore the display of the photo preview interface 1106.

[0339] 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 responds to the user's operation and shrinks or enlarges the image. Taking the user performing a two-finger zoom operation as an example, the foldable screen mobile phone can display the enlarged image on the secondary screen as follows Fig.26 As shown in Figure (c) in the figure, the two-finger zoom operation may include a two-finger pinch operation.

[0340] In another embodiment, the folding screen mobile phone displays Fig.26 In the interface shown in FIG. (b) of FIG. 1 , if the user unfolds the folding screen to the unfolded state, the main screen and the secondary screen simultaneously display the image preview interface 2603 (also referred to as the second interface), such as Fig.26 As shown in Figure (d).

[0341] 9. Folding the phone when taking photos with the front camera unfolded

[0342] In this embodiment, in the unfolded front selfie scene, the phone is directly folded, and the folding screen phone responds to the user's operation and enters the folded front selfie scene. Afterwards, the user can enter the rear selfie function by clicking the rear selfie control or flipping to wake up.

[0343] When users take front-facing selfies in the unfolded state, both the main screen and the sub-screen are facing 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.

[0344] The following is a description with reference to the accompanying drawings.

[0345] For example, Fig. 27 This is a schematic diagram of the interface changes of a foldable mobile phone when taking a front-facing photo in an unfolded state provided in an embodiment of the present application. Fig. 27 As shown in FIG. 27 (a), the folding screen mobile phone is in the unfolded state, the user is taking pictures with the rear camera, and the main screen and the secondary screen jointly display the picture preview interface 2701. The picture preview interface 2701 includes the image obtained by the rear camera.

[0346] 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 mobile phone flips the camera, obtains an image through the front camera, and displays the photo preview interface 2501 through the main screen and the secondary screen. Fig. 27 As shown in Figure (b).

[0347] Afterwards, the user folds the phone to the folded state. Taking the sliding selfie entry mode set by the user as an example, in response to the user's operation, the secondary screen of the folding screen phone turns off, and the photo preview interface 1401 is displayed through the main screen. The photo preview interface 1401 includes the image obtained by the front camera, such as Fig. 27 As shown in Figure (c).

[0348] It can be understood that if the selfie entry mode set by the user is tiled, the flip camera control 909 and the slide indicator arrow 910 in the photo preview interface 1401 are replaced by Fig. 9 The second capsule 914 and the flip camera control 909 and the rear selfie control 902 displayed in the second capsule 914 are shown and will not be described in detail.

[0349] Based on the photo preview interface 1401, the user can slide up at 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.

[0350] 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, Fig.28 This is a schematic diagram of the structure of a folding screen mobile phone 20 provided in an embodiment of the present application. The folding screen mobile phone 20 is an inner folding screen mobile phone. Fig.28 As shown, the folding screen mobile phone 20 includes a first structural member 21, a second structural member 22, and a connecting component 23 (located at Fig.28 In the position shown by the dotted line in (a) of the figure), the first structural member 21 and the second structural member 22 are flipped and folded through the connecting component 23.

[0351] The first structural member 21 may include a first inner display screen 211 and a back shell 212. The first inner display screen 211 is provided with a first front camera 2111. The first back shell 212 is provided at the back of the first inner display screen 211. The back shell 212 may be provided with a rear camera 2122.

[0352] 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.

[0353] During use, the angle between the first structural member 21 and the second structural member 22 is changed by the connecting component 23 to realize various forms of the folding screen mobile phone 20. It can be understood that the second inner display screen 221 and the first inner display screen 211 can actually be an integrally formed flexible display screen (i.e., a foldable screen, also referred to as the inner display screen of the inner folding screen mobile phone). When the folding screen mobile phone 20 is folded by the connecting component 23, the connecting component 23 divides the screen into two parts: the second inner display screen 221 and the first inner display screen 211.

[0354] like Fig.28 As shown in Figure (a), when the angle between the first structural member 21 and the second structural member 22 is approximately 180°, the folding 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 folding screen mobile phone 20 simultaneously displays the content to be displayed 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 the user's touch operation.

[0355] Folding screen mobile phone 20 is in Fig.28 In the unfolded state shown in FIG. 1 (a), when the first inner display screen 211 and the second inner display screen 221 are both on, the user can gradually move the foldable screen mobile phone 20 inward ( Fig.28 The foldable screen mobile phone 20 is folded in the direction indicated by the arrow in (a) to put it into the support state. Fig.28 As shown in Figure (b).

[0356] When the folding screen mobile phone 20 is in the bracket state, if the angle between the first structural member 21 and the second structural member 22 is greater than 45°, the first inner display screen 211 and the second inner display screen 221 are kept lit at the same time. When the angle between the first structural member 21 and the second structural member 22 gradually decreases to about 45°, the first inner display screen 211 and the second inner display screen 221 are turned off, and the outer display screen 222 is turned on, and the outer display screen 222 displays the content to be displayed. In the subsequent folding process, only the outer display screen 222 is kept lit until the angle between the first structural member 21 and the second structural member 22 is about 0°, as shown in the figure. Fig.28 The folded state shown in Figure (c).

[0357] like Fig.28As shown in Figure (c), when the foldable screen mobile phone 20 is in the folded state, the first inner display screen 211 and the second inner display screen 221 are opposite to each other and are folded inward, and the outer display screen 222 is located outside. In the folded state, the light emitting direction of the outer display screen 222 is the same as the light entering direction of the rear camera.

[0358] When the inner folding screen mobile phone realizes the functions described in the above embodiments, unlike the outer folding screen mobile phone, the inner folding screen, when in the unfolded state, displays the interface of the main screen of the outer folding screen mobile phone in the folded state through the first inner display screen and the second inner display screen. When the camera application enters the rear selfie function, the first inner display screen and the second inner display screen are turned off, and the outer display screen is turned on, and the photo preview interface under the rear selfie function is displayed through the outer display screen. In addition, in the above embodiments, the interface change triggered by unfolding the outer folding screen mobile phone to the unfolded state can be triggered by folding the inner folding screen mobile phone to the folded state for the inner folding screen.

[0359] For example, Fig.29 This is a schematic diagram of an example of interface changes based on an inward folding screen mobile phone entering the rear selfie function provided in an embodiment of the present application. Fig.29 As shown in (a) of FIG. 2 , when the folding screen (inner folding screen) mobile phone is in the unfolded state, the first inner display screen and the second inner display screen of the folding screen mobile phone are both in the light screen state, the outer display screen is in the off screen state, and the first inner display screen and the second inner display screen display the photo preview interface 2901. The photo preview interface 2901 includes a rear selfie control 2902.

[0360] The user clicks on the rear selfie control 2902. In response to the user's operation, the foldable screen mobile phone displays a flip guide interface 2903 through the first inner display screen and the second inner display screen. Fig.29 The content of the flip guide interface 2903 may be similar to the content of the flip guide interface 1105, except that the structural form of the folding screen mobile phone schematic diagram 2913 is different.

[0361] After the flipping 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 acquired through the rear camera, and the photo preview interface 2904 is displayed through the external display screen. The photo preview interface 2904 includes the image acquired 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) acquired through the rear camera can be displayed in the photo preview interface 2904, such as Fig.29 As shown in Figure (c).
