[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 and a rear camera, the folding screen includes a first screen and a second screen, the rear camera and the first screen are arranged back to back, when the electronic device is in an unfolded state, the first screen and the second screen are on the same side, and when the electronic device is in a folded state, the second screen and the rear camera are on the same side, the method comprising:

[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 operation from the user is received; in response to the first operation, the first screen is controlled to be off, and the second screen is controlled to be lighted, and a first photo preview interface is displayed through the second screen, wherein the first 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 photo preview interface is also the photo preview interface in the rear selfie scene.

[0009] Optionally, the first operation can be any one of the following operations: clicking on the rear selfie control, flipping the electronic device, clicking on the selfie icon or selfie option in the main interface, exiting the camera settings interface after turning on the rear selfie function in the camera settings interface, or setting the default selfie mode to the rear selfie in the camera settings interface and then exiting the camera settings interface, etc.

[0010] The first aspect provides a photographing method, in which, 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-screen state, the user can trigger the rear selfie function through a first operation, that is, the first screen of the electronic device is off, the second screen is on, and the first photographing preview interface in the rear selfie scene is displayed through the second screen. Since the second screen and the rear camera are on the same side in the folded state, the user can use the rear camera to 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 first photographing preview interface, that is, in the rear selfie scene, the image is obtained through the rear camera. The specifications and hardware configuration of the rear camera are relatively high, the image quality captured is relatively high, the shooting effect is relatively good, and the user experience can be improved.

[0011] In a possible implementation, before receiving the first operation of the user, the method further includes: displaying a second photo preview interface through the first screen, the second photo preview interface including a first control; and the first operation is an operation acting on the first control.

[0012] The second photo preview interface may be a photo preview interface in a rear non-selfie scene, or a photo preview interface in a front selfie scene. That is, the user can enter the rear selfie function by performing the first operation on the first control in a rear non-selfie scene; or the user can enter the rear selfie function by performing the first operation on the first control in a front selfie scene.

[0013] The operation acting on the first control may be, for example, clicking on the first control. When the user enters the rear selfie function in a rear non-selfie scene, the first control may be, for example, a rear selfie control in a photo preview interface in a rear non-selfie scene, and the operation acting on the first control may be clicking on the rear selfie control. When the user enters the rear selfie function in a front selfie scene, the first control may be, for example, a setting control or a rear selfie control in a photo preview interface in a rear non-selfie scene. When the first control is a setting control, the operation acting on the first control may include, in sequence, clicking on the setting control (entering the camera setting interface after clicking), turning on the rear selfie function switch or selecting the selfie mode as the rear selfie, and exiting the camera setting interface. When the first control is a rear selfie control, the first operation may be clicking on the rear selfie control.

[0014] In this implementation, the user can quickly enter the rear selfie function by performing the first operation on the first control, which facilitates operation and improves user experience.

[0015] In a possible implementation, the electronic device also includes a front camera, which is located on the same side as the first screen, and the second photo preview interface includes an image acquired through the rear camera or an image acquired through the front camera.

[0016] When the second photo preview interface includes an image acquired by the rear camera, it corresponds to entering the rear selfie function from the rear non-selfie scene, and the second photo preview interface is a photo preview interface in the rear non-selfie scene. When the second photo preview interface includes an image acquired by the front camera, it corresponds to entering the rear selfie function from the front selfie scene, and the second photo preview interface is a photo preview interface in the front selfie scene.

[0017] In this implementation, the user can enter the rear selfie function from the front selfie scene, and can also enter the rear selfie function from the rear selfie scene, providing users with multiple ways to enter the rear selfie function, facilitating user operation and improving user experience.

[0018] In one possible implementation, in response to a first operation, the first screen is controlled to turn off, and the second screen is controlled to turn on, and a first photo preview interface is displayed through the second screen, including: in response to the first operation, a first flip guide interface is displayed through the first screen, and the first flip guide interface is used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, the first screen is controlled to turn off, and the second screen is controlled to turn on, and the first photo preview interface is displayed through the second screen.

[0019] In this implementation, when entering the rear-camera selfie function, before controlling the screen switch, a first flip guide interface is first displayed to guide the user to flip the electronic device, so that the user can learn how to use the rear-camera selfie function and improve the user experience.

[0020] 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.

[0021] In a possible implementation, the second photo preview interface includes an image acquired through the rear camera, and the second photo preview interface also includes guide information, where the guide information is used to guide the user to click the first control.

[0022] In this implementation, the user is guided to use the rear-mounted selfie function by displaying guidance information, so that the user can understand how to use the rear-mounted selfie function and improve the user experience.

[0023] In a possible implementation, the second photo preview interface includes an image captured by the rear camera, and the method further includes: in response to a second operation performed by the user on the first control, adding a second control to the second photo preview interface.

[0024] Optionally, the second control may be a swipe up operation on the area where the first control is located. The second control is also a camera flip control. Click the second control to enter the front selfie scene.

[0025] In this implementation, the user triggers the display of a second control in the interface through a second operation. In this way, the interface includes both a first control for entering the rear-camera selfie function and a second control for entering the front-camera selfie scene. In this way, the user can choose between rear-camera selfie or front-camera selfie according to usage needs, which is convenient for user use and improves user experience.

[0026] In one possible implementation, the second photo preview interface includes an image captured by the rear camera, and the second photo preview interface also includes a setting control. The method also includes: when the second photo preview interface is displayed on the first screen, in response to a third operation performed by the user on the setting control, displaying a camera setting interface through the first screen, the camera setting interface including setting options for the selfie mode; in response to the user's operation on the setting option, displaying a first pop-up window, the first pop-up window including a front selfie option and a rear selfie option, and the rear selfie option is in a selected state; in response to the user's operation on the front selfie option, the rear selfie option is displayed as unselected, and the front selfie option is displayed as selected; in response to the user's operation of closing the first pop-up window and exiting the camera setting interface, displaying a third photo preview interface through the first screen, the third photo preview interface including the image captured by the rear camera and the second control.

[0027] That is to say, in the rear non-selfie scene, the user selects the front selfie option in the first pop-up window, and changes the default selfie mode from rear selfie to front selfie. In this way, after the user exits the camera setting interface, the shooting scene is still the rear non-selfie scene, but the control displayed in the interface becomes the second control (camera switching control). The user clicks the camera switching control to enter the front selfie scene. In this implementation, the user can independently select the default selfie mode, and the controls in the photo preview interface change according to the user's selection, so that the interface display is more in line with the user's habitual selection, improving the user experience.

[0028] In a possible implementation, the method further includes: in response to the user clicking on the second control, displaying a fourth photo preview interface through the first screen, wherein the fourth photo preview interface includes an image acquired through the front camera.

[0029] The fourth photo preview interface is also the photo preview interface in the front-facing selfie scene.

[0030] In one possible implementation, the fourth photo preview interface includes a first control, and the method further includes: in response to a fourth operation performed by the user on the first control in the fourth photo preview interface, displaying a first flip guide interface through the first screen, the first flip guide interface being used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the first photo preview interface through the second screen.

[0031] Optionally, the first control may be a rear selfie control or a setting control. The fourth operation may be operations such as clicking the rear selfie control or setting a selfie mode through a setting control.

[0032] In a possible implementation, before receiving the first operation of the user, the method further includes: displaying a second photo preview interface through the first screen; and the first operation is an operation of flipping the electronic device.

[0033] In this implementation, the user can enter the rear-mounted selfie function by flipping the electronic device, without the user having to perform operations such as clicking on the rear-mounted selfie control in the interface. The user can enter the rear-mounted selfie function quickly and conveniently, thereby improving the intelligence of the electronic device and further improving the user experience.

[0034] In a possible implementation, the second photo preview interface includes an image acquired through a rear camera.

[0035] That is to say, the user can enter the rear selfie function from the rear selfie scene by flipping the electronic device.

[0036] In a possible implementation, the shooting mode in the first photo preview interface is the same as the shooting mode in the second photo preview interface.

[0037] 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.

[0038] In one possible implementation, before receiving the user's first operation, the method also includes: displaying a main interface through the first screen, the main interface including an icon of a camera application; in response to the user long pressing the camera application icon, displaying a first service card through the first screen, the first service card including a selfie option; the first operation is clicking on the selfie option.

[0039] In this implementation, the user can enter the rear-camera selfie function through the selfie option in the main interface, without the user having to open the second photo preview interface, or click on the rear-camera selfie control or setting control in the second photo preview interface, thereby simplifying the user's operation process of entering the rear-camera selfie function and improving the user experience.

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

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

[0042] In one possible implementation, in response to a first operation, the first screen is controlled to turn off, and the second screen is controlled to turn on, and a first photo preview interface is displayed through the second screen, including: in response to the first operation, starting a camera application; displaying a first flip guide interface through the first screen, the first flip guide interface is used to guide the user to flip the electronic device; after the first flip guide interface is displayed for a first preset time, the first screen is controlled to turn off, and the second screen is controlled to turn on, and the first photo preview interface is displayed through the second screen.

[0043] In this implementation, the user is guided to use the rear-mounted selfie function by displaying the first flip guide interface, so that the user can understand how to use the rear-mounted selfie function and the user experience is improved.

[0044] In one possible implementation, the method also includes: when the first photo preview interface is displayed on the second screen, in response to a fourth operation performed by the user on the first screen, exiting the camera application to the background; controlling the second screen to turn off, and controlling the first screen to turn on; in response to the fourth operation performed by the user on the first screen, controlling the camera application to run in the foreground, and displaying the first flip guide interface through the first screen; after the first flip guide interface is displayed for a first preset time, controlling the first screen to turn off, and controlling the second screen to turn on, and displaying the first photo preview interface through the second screen.

[0045] The fourth operation is to exit the camera application to the background. In this implementation, if the user exits the camera application to the background, 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.

[0046] In one possible implementation, the first photo preview interface includes a third control, and the third control includes a thumbnail. The method also includes: when the first photo preview interface is displayed on the second screen, in response to the user clicking the third control, the first interface is displayed through the second screen, and the first interface includes an image corresponding to the thumbnail.

[0047] The third control is the thumbnail of the image taken by the user in the photo preview interface. The first interface is the image preview interface in the folded state.

[0048] In this implementation, when the user uses the rear Selfie function, the user can view the captured image through the image thumbnail in the first photo preview interface. The image can be displayed on the second screen. 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.

[0049] 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.

[0050] The second interface is the image preview interface in the expanded state.

[0051] 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.

[0052] In one possible implementation, the method also includes: when the first photo preview interface is displayed on the second screen, in response to the user unfolding the electronic device to the unfolded state, controlling the first screen to light up, and displaying a fifth photo preview interface through the first screen and the second screen together, the fifth photo preview interface including an image acquired through the rear camera.

[0053] The fifth photo preview interface is the photo preview interface for the rear non-selfie scene in the expanded state.

[0054] In this implementation, when the user unfolds the electronic device, the camera application exits the rear selfie function and enters the rear non-selfie scene in the unfolded state. If the user unfolds the electronic device to the unfolded state, it means that the user no longer needs the rear selfie function, so directly entering the unfolded state rear shooting scene is likely to meet the user's usage needs and improve the user experience.

[0055] In one possible implementation, the first photo preview interface includes a second control and a fourth control, and the method further includes: when the first photo preview interface is displayed on the second screen, in response to the user clicking the fourth control or the second control, a second flip guide interface is displayed through the second screen, and the second flip guide interface is used to guide the user to flip the electronic device; after the second flip guide interface is displayed for a second preset time, the second screen is controlled to turn off, and the first screen is controlled to turn on, and the second photo preview interface is displayed through the first screen, and the second photo preview interface includes an image acquired through the rear camera.

[0056] The second control may be a flip camera control. The fourth control may be a home screen switch control or a rear selfie exit control.

[0057] When using the rear Selfie function, the user can exit the rear Selfie function through the switch main screen control or the flip camera control or the rear Selfie exit control in the first photo preview interface. After exiting the rear Selfie function, the camera application enters the rear non-selfie scene in the folded state, the electronic device turns off the second screen, lights up the first screen, and displays the second photo preview interface through the first screen. In other words, when using the rear Selfie function, the user can exit the rear Selfie function at any time with one click, which is convenient for user operation and use and improves user experience.

[0058] In a second aspect, the present application provides a device, which is included in an electronic device, and the device has the function of implementing the electronic device behavior in the above-mentioned first aspect and the possible implementation of the above-mentioned first aspect.

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.

[0092] 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.

[0093] 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.

[0094] For example, Figure 1 1 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 112 can jointly display the interface of the same application, or they can display the interfaces of different applications in split screens.

[0099] 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 1 The 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.

[0100] 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.

[0101] 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.

[0102] 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 112 does not display and can be in the off-screen state. It should be noted that when the secondary screen 112 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.

[0103] 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.

[0104] 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 122, 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. 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 122, as shown in FIG. Figure 4 As shown in Figure (b), this shooting scene is also called a front-facing selfie scene in the unfolded state.

[0105] 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.

[0106] 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.

[0107] 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 122 lights up, and the user can control the photo taking and view the captured images through the sub-screen 122. 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).

[0108] 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.

[0109] For example, Figure 6 1 is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application. The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a sensor module 180, a button 190, a camera 193, and a display screen 194. The sensor module 180 may include an angle sensor 180A, a gyroscope sensor 180B, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a touch sensor 180K, and the like.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] The angle sensor 180A is used to detect the angle between the first structural member and the second structural member, so as to determine whether the 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.

[0122] 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.

[0123] In the embodiment of the present application, one or more of the gyroscope sensor 180B, the magnetic sensor 180D, the accelerometer 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] The application framework layer 220 provides an application access interface and a programming framework for the application programs of the application layer 210 .

[0129] 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.

[0130] 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.

[0131] The camera device in the application framework layer 220 is used to provide a data access interface between different camera devices and camera management.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] To facilitate understanding, several terms involved in the following embodiments are first explained.

[0141] 1. Enable the function

[0142] In the embodiment of the present application, when the foldable screen mobile phone has a certain function, turning on the function means turning on the switch of the function so that the foldable screen mobile phone can use the function. After turning on a certain function, the function is said to be in an on state, an on state, or the function is said to be turned on.

[0143] 2. Turn off the function

[0144] 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.

[0145] 3. Enter the function

[0146] 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.

[0147] 4. Exit function

[0148] 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.

[0149] In the implementation of this application, the camera application in the folding screen mobile phone has a rear selfie function. When the rear selfie function is turned on, the user can take selfies through the rear camera to improve the quality and effect of the selfie image. The following describes the relevant process according to the use stage of the rear selfie function and the application scenario.

[0150] 1. Turning the rear selfie function on and off

[0151] 1. Enable the rear selfie function

[0152] For example, Figure 8908 is a schematic diagram of interface changes during the process of enabling the rear-mounted selfie function provided by an embodiment of the present application. Taking the foldable screen mobile phone in the folded state as an example, when the rear-mounted selfie function is not enabled, after the camera application is started, the foldable screen mobile phone acquires an image through the rear camera, and displays a photo preview interface 908 through the main screen. The photo preview interface 908 includes the image acquired by the rear camera, such as Figure 8 In other words, when the photo preview interface 908 is folded and the rear selfie function is turned off, the rear non-selfie scene preview interface. Figure 8 As shown in FIG. 1 (a), when the rear selfie function is turned on, the photo preview interface 908 includes a camera flip control 909 (also referred to as a second control). The camera flip control 909 is used for the user to control the switch between the rear camera and the front camera.

[0153] The photo preview interface 908 also includes a setting control 903. The user clicks the setting control 903, and the folding screen mobile phone responds to the user's operation and displays the camera setting interface 904, such as Figure 8 The camera setting interface 904 includes a rear selfie option 905. The user clicks the rear selfie option 905, and the foldable screen mobile phone responds to the user's operation and displays a rear selfie setting interface 906, as shown in FIG. Figure 8 As shown in Figure (c).

[0154] The rear Selfie setting interface 906 includes a switch control of the rear Selfie function (referred to as the rear Selfie switch) 907. Figure 8 As shown in Figure (c) of FIG. 1 , the rear selfie switch 907 is in the off state and is grayed out. The user clicks the rear selfie switch 907, and the foldable screen mobile phone responds to the user's operation and turns on the rear selfie function, and the rear selfie switch 907 is highlighted. Figure 8 As shown in Figure (d).

[0155] Afterwards, the user can perform two return operations, exiting the rear selfie setting interface 906 and exiting the camera setting interface 904, and the folding screen mobile phone displays the photo preview interface 901 (also called the second photo preview interface). Figure 8As shown in Figure (e) in the figure. The photo preview interface 901 is a preview interface for the rear non-selfie scene when the photo preview interface 901 is in a folded state and the rear selfie function is turned on. Unlike the photo preview interface 908, the photo preview interface 901 displays a rear selfie control (also called a first control) 902. Optionally, the photo preview interface 901 can be an interface obtained by replacing the camera flip control 909 in the photo preview interface 908 with the rear selfie control 902 based on the photo preview interface 908. Optionally, the photo preview interface 901 can also be an interface obtained by adding a rear selfie control 902 based on the photo preview interface 908, that is, the selfie control 902 and the camera flip control 909 can be displayed in the interface at the same time. The rear selfie control is used to enter the rear selfie function. Optionally, the return operation can be, for example, a side sliding operation (i.e., sliding inward from the side of the screen), clicking the return key in the three-button navigation bar, or clicking the return control in the interface, etc., and the present application embodiment does not make any limitation on this. The return operation in the following embodiments is also the same and will not be repeated.

[0156] It is understandable that the rear selfie function of the foldable screen mobile phone can be turned on by default when it leaves the factory. After that, the user can turn off the rear selfie function as needed during use.

[0157] 2. Turn off the rear selfie function

[0158] The process of turning off the rear Selfie function is similar to the above-mentioned turning on process. The difference is that the turning on process is to switch the rear Selfie switch 907 from the off state to the on state, while the turning off process is to switch the rear Selfie switch 907 from the on state to the off state. It will not be repeated here.

[0159] It should be noted that the above-mentioned process of turning on and off the rear selfie function is described by taking the folding screen mobile phone in the folded state as an example. When the folding screen mobile phone is in the unfolded state, the rear selfie function can also be turned on or off. The operation process and the interface change process are similar to the above process and will not be repeated. In addition, in this embodiment, the rear selfie setting interface 906 is entered through the camera setting interface 904 to turn on or off the rear selfie function. In other embodiments, the rear selfie setting interface 906 can also be entered by other means. For example, the rear selfie setting interface 906 can be entered through the setting application of the folding screen mobile phone. This application does not impose any limitation on this.

[0160] In this embodiment, the user can independently set the on and off of the rear selfie function as needed to meet the usage requirements of different scenarios, facilitate user operation, and improve user experience.

[0161] 2. Display of rear selfie controls and flip camera controls

[0162] As mentioned above Fig. 9 As shown in FIG. 1 (a), when the rear selfie function is turned on, the photo preview interface 901 includes a rear selfie control 902. In another embodiment, the photo preview interface 901 may also include a flip camera control 909. The user clicks the flip camera control 909 to enter the front selfie scene, and the photo preview interface 1501 in the front selfie scene is displayed (same as FIG. 15). Figure 5 The front Selfie scene refers to a scene where a Selfie is taken through the front camera. For the photo preview interface 1501, please refer to the following embodiments. Fig.15 That is to say, in this embodiment, the photo preview interface 901 may include both a control for entering the rear Selfie and a control for entering the front Selfie, so that the user can choose the rear Selfie or the front Selfie according to the use requirements, which is convenient for the user to use and improves the user experience.

[0163] In another embodiment, when the foldable screen mobile phone displays the photo preview interface 901 through the main screen, the user can call out the flip camera control 909 through a preset gesture. Fig. 9 This is a schematic diagram of a process for calling a flip camera control provided in an embodiment of the present application. Fig. 9 As shown in Figure (a), when the foldable screen mobile phone is in the folded state and the rear selfie function is turned on, after the camera application is started, the photo preview interface 1901 is displayed.

[0164] The photo preview interface 1901 includes a rear selfie control 902, and an arrow mark 1902 is displayed above the rear selfie control 902. Optionally, the user can click the arrow mark 1902 (also called the second operation), or slide up at the rear selfie control 902 (also called the second operation). In response to the user's operation, the foldable screen mobile phone displays a capsule 1903 in the area where the rear selfie control 902 was originally located, such as Fig. 9 As shown in Figure (b) in the figure, the capsule 1903 includes a rear selfie control 902 and a flip camera control 909, and the user can choose to click according to the needs.

[0165] If the user does not select a control in capsule 1903 after capsule 1903 is displayed for a preset time, that is, the user does not operate capsule 1903 within the preset time, capsule 1903 is hidden and the interface is restored to the photo preview interface 1901. Fig.18 As shown in Figure (c).

[0166] In this embodiment, the user can call out the capsule through a preset operation, and choose to click the rear selfie control 902 or the flip camera control 909 in the capsule to control the camera to enter the rear selfie function or the front selfie scene. In this way, on the one hand, the user can choose the rear selfie or the front selfie according to usage needs, which is convenient for user use and improves the user experience; on the other hand, when the user does not perform the preset gesture, the front selfie scene is not displayed in the interface, which facilitates the arrangement of controls in the interface, prevents the controls in the interface from being too crowded and affecting user operations, and further improves the user experience.

[0167] 3. Flip wake-up settings

[0168] In an embodiment of the present application, when the rear selfie function is turned on, the camera application of the foldable screen mobile phone may also have a "flip wake-up rear selfie function" (referred to as the flip wake-up function). The flip wake-up function is off by default, and the user can manually turn on the function. After the flip wake-up function is turned on, when the user lifts the phone to face the face and looks at the screen according to the flip wake-up requirements, and then the user flips the phone, the foldable screen phone recognizes the face through the front camera, detects that the user flips the phone through the sensor, and then recognizes the face through the rear camera, triggering the camera application to automatically enter the rear selfie function. The operation of the user flipping the phone according to the above requirements is also called the first operation.

[0169] The setting process of the flip wake-up function is similar to that of the rear selfie function, which is briefly described below with reference to the accompanying drawings.

[0170] 1. Enable the flip wake-up function

[0171] For example, Fig.10 This is a schematic diagram of the interface changes during the setting process of the flip wake-up function provided in an embodiment of the present application. Fig.10 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 Figure 8 The process shown in Figures (a) to (c) in FIG. 1 enters the rear selfie setting interface 906. For the specific process, see Figure 8 The illustrated embodiments will not be described in detail.

[0172] like Fig.10 As shown in Figure (a) in the figure, the rear selfie switch 907 in the rear selfie setting interface 906 is now in the on state and is highlighted. The rear selfie setting interface 906 includes a switch control (referred to as the flip wake-up switch) 1001 for flipping and waking up the rear selfie function. The flip wake-up switch 1001 is in the off state by default and is grayed out. The user clicks the flip wake-up switch 1001, and the foldable screen mobile phone responds to the user's operation and turns on the flip wake-up function, and the flip wake-up switch 1001 is highlighted, as shown in Figure 1. Fig.10As shown in Figure (b).

[0173] Afterwards, the user performs two return operations, and the foldable screen mobile phone successively exits the rear selfie setting interface 906 and the camera setting interface 904, and restores the photo preview interface 901. Fig.10 As shown in Figure (c).

[0174] 2. Turn off the flip wake function

[0175] 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 1001 from the on state to the off state, which will not be repeated here.

[0176] In this embodiment, the user can independently set the flip wake-up function to be turned on and off as needed to meet the different usage habits of the user, to meet the needs of different usage scenarios of the user, to facilitate user operation, and to improve user experience.

[0177] 4. The introduction of the rear selfie function

[0178] When the rear selfie function is turned on, the user can enter the rear selfie function through the corresponding operation when using the camera application. 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 first photo preview interface) on the sub-screen, and the photo preview interface 1106 includes the image obtained by the rear camera. In other words, the photo preview interface 1106 is the photo preview interface in the rear selfie scene, that is, the photo preview interface when the rear selfie function is used. 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.

[0179] In the embodiments of the present application, a variety of ways to enter the rear selfie function are provided, which are described below in combination with the scenarios.

[0180] 1. Start the camera for the first time and enter the rear selfie function

[0181] As described above, the rear Selfie function of the foldable screen mobile phone is turned on by default when it leaves the factory. When the user starts the camera application of the foldable screen mobile phone for the first time, the foldable screen mobile phone starts the photo preview interface 901 by default, and displays guidance information in the photo preview interface 901 to guide the user to use the rear Selfie function, so that the user can understand how to use the rear Selfie function and improve the user experience.

[0182] For example, Fig.11 1 is a schematic diagram of an interface change in a process of guiding the user to enter the rear Selfie 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, the secondary screen of the foldable screen mobile phone is in the off state, the main screen is in the on state, and the main screen displays the main interface 1101.

[0183] It should be noted that, in general, when the folded phone is in the main screen state, 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.

[0184] The main interface 1101 includes a camera application icon 1102. The user clicks the camera application icon 1102 to trigger the first launch of the camera application. In response to the user's operation, the foldable screen mobile phone acquires an image through the rear camera by default, and displays a photo preview interface 1103 (also called a second photo preview interface) through the main screen, such as Fig.11 The photo preview interface 1103 is similar to the above Figure 8 The photo preview interface 1103 is similar to the photo preview interface 901 shown in (a) of FIG. 1 , except that, in this embodiment, the user starts the camera application of the foldable screen mobile phone for the first time, so the photo preview interface 1103 also includes guidance information 1104. The guidance information 1104 is used to guide the user to enter the rear selfie function through the rear selfie control 902.

[0185] Optionally, the guidance information 1104 may be displayed in the form of bubbles, cards, capsules, etc. The guidance information 1104 may include prompt text or prompt pictures for introducing the rear selfie function. Fig.11 In Figure (b), the guidance information 1104 may include a prompt picture (a selfie picture of a person) and prompt text such as "Use the rear selfie super-sensitive portrait lens to take better portrait effects."

[0186] The user clicks on the rear selfie control 902 (also referred to as the first operation). In response to the user's operation, the foldable screen mobile phone displays a flip guide interface (also referred to as the first flip guide interface) 1105 through the main screen. Fig.11As shown in Figure (c) 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."

[0187] 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 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 of the rear selfie function, thereby improving the user experience.

[0188] 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 secondary screen to light up. At the same time, the image is acquired through the rear camera, and the photo preview interface 1106 is displayed through the secondary screen. The photo preview interface 1106 includes the image acquired by the rear camera. After the user flips the folding screen mobile phone, the side where the secondary screen is located (that is, the side where the rear camera is located) faces the user, and the side where the main screen is located faces away from the user. In this way, the user's own image (that is, the selfie image) acquired by the rear camera can be displayed in the photo preview interface 1106, such as Fig.11 As shown in Figure (d).

[0189] Optionally, in some other embodiments, when the main screen displays the flipping guide interface 1105, the secondary screen may light up at the same time, and acquire 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 secondary screen displays the flipping guide interface 1105, and the secondary screen lights up, and displays the photo preview interface 1106 through the secondary screen.

[0190] Optionally, while the secondary screen displays the flip guide interface 1105, the folding screen mobile phone can block the touch function of 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 function of the main screen and the secondary screen is blocked. This can prevent users from accidentally touching the screen and improve the user experience.

[0191] 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.

[0192] 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 1103. 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.

[0193] It is understandable that when the user is not using the camera for the first time (the second time and every time thereafter), the guide information may no longer be displayed in the photo preview interface to prevent disturbing the user and further improve the user experience. When the camera is not used for the first time, the method of entering the rear selfie function and the interface display are the same as the above process and will not be repeated.

[0194] 2. Flip the phone to wake up the rear selfie function

[0195] As mentioned above, the camera application of the foldable screen mobile phone can have a flip wake up rear selfie function. When the flip wake up rear selfie function and the rear selfie function are turned on at the same time (refer to Fig.10 ), 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. In this way, the user does not need to perform operations such as clicking the rear selfie control in the interface, and can quickly and conveniently enter the rear selfie function, thereby improving the intelligence of the mobile phone and thus improving the user experience. The following is an explanation with reference to the accompanying drawings.

[0196] For example, Fig.12 This is a schematic diagram of the interface changes during the process of flipping a mobile phone to wake up the rear selfie provided in an embodiment of the present application. Fig.12 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, and the main screen is in the on state. When the foldable screen mobile phone starts the camera application and the rear selfie function is turned on but not entered, the main screen displays the photo preview interface 901. At this time, the side where the main screen of the foldable screen mobile phone is facing the user, and the side where the secondary screen is facing away from the user.

[0197] 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.12 As shown in Figure (b).

[0198] 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 901 is displayed on the main screen, as shown in FIG. Fig.12 As shown in Figure (a).

[0199] 3. Enter the rear selfie function through the desktop shortcut menu (also known as the desktop long press menu shut cut)

[0200] In this embodiment, when the rear-camera selfie function is turned on, the user can also directly enter the rear-camera selfie function through the desktop shortcut menu, without the user having to open the photo preview interface 901 or click on the rear-camera selfie control in the photo preview interface 901, thereby simplifying the user's operation process of entering the rear-camera selfie function and improving the user experience.

[0201] For example, Fig.13 A schematic diagram of the interface changes in the process of entering the rear selfie function through the desktop shortcut menu provided in an embodiment of the present application. When the foldable screen mobile phone is in the folded state, the secondary screen of the foldable screen mobile phone is in the off state, the main screen is in the on state, and the main screen displays the main interface 1101, such as Fig.13 As shown in Figure (a).

[0202] The main interface 1101 includes a camera application icon 1102. The user long presses the camera application icon 1102, and the foldable screen mobile phone responds to the user's operation, displays a mask in the interface, and displays a shortcut menu (also called a first service card) 1301 of the camera application, such as Fig.13 As shown in Figure (b).

[0203] The shortcut menu 1301 includes a selfie option 1302. When the rear selfie function is turned on, the user clicks the selfie option 1302, the foldable screen mobile phone starts the camera application, and displays the flip guide interface 1105 through the main screen, such as Fig.13 As shown in Figure (c).

[0204] 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.13 As shown in Figure (d).

[0205] It should be noted that when the user clicks on the selfie option 1302, if the rear selfie function is turned off, the foldable screen mobile phone starts the camera application, obtains an image through the front camera, and displays the photo preview interface 1501 (also called the second photo preview interface) through the main screen. The photo preview interface 1501 displays the image obtained by the front camera. The photo preview interface 1501 is a preview interface in the front selfie scene. For details about the photo preview interface 1501, please refer to the following embodiments. Fig.15 Interface 1501 in.

[0206] For example, Fig.14 This is another example of the interface changes in the process of entering the rear Selfie function through the desktop shortcut menu provided in the embodiment of the present application. Fig.13 As shown in Figure (b) Fig.14 As shown in Figure (a) in FIG. 1 , when the foldable screen mobile phone displays the shortcut menu 1301 of the camera application, the user can also long press and drag the selfie option 1302 to a certain position in the main interface 1101. After the user raises his hand, a desktop shortcut icon (referred to as the selfie shortcut icon, also called the selfie icon) 1401 of the selfie function is displayed at the position where the hand is raised. Fig.14 As shown in Figure (b).

[0207] When the rear selfie function is turned on, the user clicks the selfie shortcut icon 1401, and the foldable screen mobile phone responds to the user's operation, starts the camera application, and displays the flip guide interface 1105 through the main screen, such as Fig.14 After the flipping guide interface 1105 displays the preset time, the camera application enters the rear Selfie function and displays the photo preview interface 1106, as shown in FIG. Fig.14 As shown in Figure (d).

[0208] Similarly, when the user clicks on the selfie shortcut icon 1401, if the rear selfie function is turned off, the foldable screen mobile phone starts the camera application to obtain the image through the front camera, and displays the photo preview interface 1501 through the main screen. The photo preview interface 1501 includes the image obtained through the front camera.

[0209] 4. Enter the rear selfie function from the front selfie scene

[0210] When the foldable phone is in the folded state and the rear selfie function is turned off, the camera app can enter the front selfie scene. In the front selfie scene, the user can turn on the rear selfie function again. After the rear selfie function is turned on, the foldable phone directly guides the user to flip the phone, and then the camera app automatically enters the rear selfie function without the user having to return to the photo preview interface or click on the rear selfie control, which improves user convenience and further improves the user experience.

[0211] Optionally, when the rear selfie function is turned off, the user can Fig.13 The selfie option 1302 shown in the figure enters the front selfie scene, or you can click the above Fig.14 The selfie shortcut icon 1401 shown enters the front selfie scene.

[0212] Optionally, the user can also enter the front selfie scene by flipping the camera control 909 in the photo preview interface 908. The following is a description of the process of entering the front selfie scene and entering the rear selfie function from the front selfie scene in conjunction with the accompanying drawings.

[0213] For example, Fig.15 and Fig.16 This is a schematic diagram of an interface change in a process of entering a rear selfie function from a front selfie scene provided in an embodiment of the present application, wherein: Fig.16 Figure (a) continues Fig.15 Figure (d) in .

[0214] like Fig.15 As shown in Figure (a), the foldable screen mobile phone is in a folded state, the secondary screen of the foldable screen mobile phone is in an off state, and the main screen is in an on state. When the rear selfie function is turned off, after the camera application of the foldable screen mobile phone is started, the main screen displays a photo preview interface 908, which includes an image obtained by the rear camera.

[0215] The photo preview interface 908 also includes a flip camera control 909. The user clicks the flip camera control 909, and the folding screen mobile phone responds to the user's operation, switches the rear camera to the front camera, obtains an image through the front camera, and displays the photo preview interface 1501 through the main screen, such as Fig.15As shown in Figure (b).

[0216] The photo preview interface 1501 includes a setting control 903. The user clicks the setting control 903, and in response to the user's operation, the folding screen mobile phone displays a camera setting interface 904, such as Fig.15 As shown in Figure (c) in FIG. 904, the camera setting interface 904 includes a rear selfie option 905. The user clicks the rear selfie option 905, and in response to the user's operation, the foldable screen mobile phone displays a rear selfie setting interface 906, as shown in FIG. Fig.15 As shown in Figure (d).

[0217] The rear selfie setting interface 906 includes a rear selfie switch 907. The rear selfie switch 907 is currently in an off state and is grayed out. The user clicks the rear selfie switch 907, and the foldable screen mobile phone responds to the user's operation and turns on the rear selfie function, and the rear selfie switch 907 is highlighted. Fig.16 As shown in Figure (a).

[0218] Afterwards, the user performs a return operation. In response to the user's operation, the foldable screen mobile phone exits the rear selfie setting interface 906 and displays the camera setting interface 904 through the main screen. Fig.16 As shown in Figure (b) in the figure. Then, the user performs a return operation again. In response to the user's operation, the foldable screen mobile phone exits the camera setting interface 904 and displays the flip guide interface 1105 through the main screen, as shown in Figure (b). Fig.16 As shown in Figure (c).

[0219] After the flip guide interface 1105 is displayed for a preset time, the camera application enters the rear selfie function, the folding screen mobile phone controls the main screen to turn off, the sub-screen to light up, and at the same time, the image is obtained through the rear camera, and the photo preview interface 1106 is displayed through the sub-screen. The photo preview interface 1106 includes the image obtained by the rear camera, such as Fig.16 As shown in Figure (d).

[0220] 5. After entering the rear selfie function, exit the camera application and go to the background

[0221] After entering the rear Selfie function through the methods 1, 3, and 4 in the above “III. Entering the rear Selfie function”, 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 users, there is no need to repeat the operation to enter the rear Selfie function, which simplifies user operations and improves user experience.

[0222] For example, Fig.17This 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.17 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 (also called the fourth operation). Among them, the operation of exiting the camera to the background can be, for example: clicking the home button in the three-button navigation bar; after the user executes 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.). The operation of exiting the camera to the background can also be: swipe up from the bottom of the screen to enter the multitasking interface, and the user clicks on the interface thumbnail of other tasks (applications) in the multitasking interface; after the user executes 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.

[0223] Taking the example of a user clicking the home button in the three-button navigation bar, 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 1101 through the main screen, such as Fig.17 As shown in Figure (b).

[0224] After the user performs some other operations on the main screen, the user clicks the camera application icon 1102 in the main interface 1101 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.17 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.17 As shown in Figure (d).

[0225] 6. Unfolding the phone while using the rear-camera selfie function

[0226] In this embodiment, during the use of the rear selfie function, if the user unfolds the folding screen mobile phone, the camera application exits the rear selfie function and enters the rear non-selfie scene in the unfolded state. The rear non-selfie scene in the unfolded state means that the folding screen mobile phone obtains an image through the rear camera, and displays the photo preview interface 1801 (also called the fifth photo preview interface) through the main screen and the sub-screen, and the photo preview interface 1801 includes the image obtained by the rear camera. In other words, the photo preview interface 1801 is a photo preview interface for the unfolded rear non-selfie scene. The user unfolds the folding screen mobile phone to the unfolded state, which means that the user no longer needs the rear selfie function, so directly entering the unfolded state rear shooting scene is likely to meet the user's usage needs and improve the user experience.

[0227] For example, Fig.18 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.18 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.

[0228] 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 continues to obtain images through the rear camera. At the same time, the secondary screen lights up, and the main screen and the secondary screen jointly display the photo preview interface 1801. The photo preview interface 1801 includes the image obtained by the rear camera, such as Fig.18 As shown in Figure (b).

[0229] Optionally, after the user unfolds the foldable screen mobile phone through the above process and the foldable screen mobile phone enters the unfolded state and the rear camera scene, the default shooting mode is consistent with the shooting mode when the rear selfie function is used, that is, the shooting mode in the photo preview interface 1801 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.

[0230] VII. Viewing images while using the rear Selfie function

[0231] In this embodiment, when the user uses the rear Selfie function, the user can view the captured image through the image thumbnail in the photo preview interface 1106. The image can be displayed on the secondary screen, and supports functions such as 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.

[0232] 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.

[0233] The following is a description with reference to the accompanying drawings.

[0234] For example, Fig.19 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.19 As shown in Figure (a), the user is using the rear selfie function, and the folding screen mobile phone displays a photo preview interface 1106 through the secondary screen. The photo preview interface 1106 includes a thumbnail (also called a third control) 2101 of the image taken by the user.

[0235] The user clicks on the thumbnail 2101, and the foldable screen mobile phone responds to the user's operation and displays the image preview interface 2102 (also called the first interface) through the secondary screen. The image preview interface 2102 includes the image corresponding to the thumbnail 2101, such as Fig.19 As shown in Figure (b) in the figure. In addition, the image preview interface 2102 includes a collection control 2121, a delete control 2122, a switch home screen control (also called the fourth control) 2123 and a return control 2124. The user clicks the collection control 2121, and the foldable screen mobile phone collects the image. The user clicks the delete control 2122, and the foldable screen mobile phone deletes the image. The user clicks the switch home screen control 2123, 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 901. The user clicks the return control 2124, the foldable screen mobile phone will exit the current image preview interface 2102, and restore the display of the photo preview interface 1106.

[0236] In addition, if the user performs a two-finger zoom operation on the image displayed in the image preview interface 2102, the foldable screen mobile phone responds to the user's operation and 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.19 As shown in Figure (c) in the figure, the two-finger zoom operation can be, for example, a two-finger pinch operation.

[0237] In another embodiment, the folding screen mobile phone displays Fig.19 When the user unfolds the folding screen to the unfolded state, the main screen and the secondary screen simultaneously display the image preview interface 2103 (also called the second interface), such as Fig.19 As shown in Figure (d).

[0238] 8. Exit the rear selfie function

[0239] When the user is using the rear Selfie function, he can exit the rear Selfie function by switching the main screen control or flipping the camera control in the photo preview interface 1106, or by switching the main screen control in the photo preview interface. After exiting the rear Selfie function, the camera application enters the rear non-Selfie scene in the folded state, the folding screen mobile phone turns off the secondary screen, and displays the photo preview interface 901 through the main screen. In other words, when the user is using the rear Selfie function, he can exit the function at any time with one click, which is convenient for user operation and use, and improves the user experience.

[0240] For example, Fig. 20 This is a schematic diagram of an interface change for exiting the rear selfie function provided in an embodiment of the present application. Fig. 20 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. The photo preview interface 1106 includes a switch main screen control 2123 and a flip camera control 909. 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.

[0241] The user clicks the switch main screen control 2123, or clicks the flip camera control 909. In response to the user's operation, the folding screen mobile phone displays a flip guide interface 2201 (also called a second flip guide interface) through the secondary screen, such as Fig. 20 As shown in Figure (b) in the figure. The flip guide interface 2201 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 2201 may include text prompt information 2211, an arrow 2212 indicating the flipping direction, and a schematic diagram 2213 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 2201, so as to more clearly guide the user to flip the mobile phone and improve the user experience. Optionally, in this interface, the text reminder information 2211 can be, for example, "The rear selfie has exited, please flip the phone."

[0242] After the flipping guide interface 2201 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 901 is displayed through the main screen. The photo preview interface 901 includes the image acquired by the rear camera. After the user flips the mobile phone, the photo preview interface 901 can display the image of the surrounding people or objects acquired by the rear camera, such as Fig. 20 As shown in Figure (c).

[0243] In other embodiments, Fig. 20 The photo preview interface 1106 shown in FIG. 100 (a) may further include a rear Selfie exit control 2125 (also referred to as a fourth control), and the user may also exit the rear Selfie function by clicking the rear Selfie exit control 2125. After the user clicks the rear Selfie exit control 2125, the interface changes in the same manner as in FIG. Fig. 20 As shown in Figures (b) and (c) in the figure, no further details will be given.

[0244] In the above embodiments, the user can independently control the opening and closing of the rear selfie function as an example for explanation. In other embodiments, the rear selfie function of the electronic device may also be continuously in the turned-on state, that is, the rear selfie function is continuously available. In this case, the user does not need to control the opening and closing of the rear selfie function, but the user can set the default selfie mode to the rear selfie or the rear non-selfie, thereby selecting the default control displayed in the photo preview interface as the rear selfie control or the camera flip control. In this way, the display of the interface is more in line with the user's habitual choice, improving the user experience. Moreover, after displaying one of the two default controls, the user can call out the other, conveniently and quickly realizing the selection of two selfie modes. The following is further explained in conjunction with the accompanying drawings.

[0245] For example, Fig.21 This is a schematic diagram of an interface change for setting a default selfie mode provided in an embodiment of the present application. Fig.21 As shown in Figure (a), continuing to take the foldable screen mobile phone as an example, the foldable screen mobile phone is in a folded state, the main screen is in an off state, and the sub-screen is in an on state. After the camera application is started, it enters the rear non-selfie scene by default. The foldable screen mobile phone obtains the image through the rear camera, and displays the photo preview interface 1901 through the main screen. The photo preview interface 1901 includes the image obtained by the rear camera. Optionally, the default selfie mode of the foldable screen mobile phone can be a rear selfie. Therefore, the photo preview interface 1901 includes a rear selfie control 902, and an arrow mark 1902 is displayed above the rear selfie control 902. The user can call out capsule 1903 by clicking the arrow mark 1902 or swiping up. The rear selfie control 902 and the flip camera control 909 in capsule 1903 are shown in detail. Fig. 9 The embodiments shown will not be described in detail.

[0246] The photo preview interface 1901 also includes a setting control 903. The user clicks the setting control 903 (also referred to as the third operation), and the folding screen mobile phone responds to the user's operation and displays the camera setting interface 2301, such as Fig.21 As shown in FIG. (b) of FIG. 2301, the camera setting interface 2301 includes a setting option for a selfie mode (hereinafter referred to as a selfie mode option) 2302. The selfie mode currently displayed in this option is a rear selfie. In addition, the camera setting interface 2301 may also include a flip wake up rear selfie option 2305, and the user may enter the setting interface of the flip wake up function by clicking on the option 2305. Optionally, the setting interface of the flip wake up function may be the same as the above Fig.10 The embodiment is similar to Figure (a), except that the setting interface of the flip wake-up function in this embodiment does not include a rear selfie switch.

[0247] The user clicks on the selfie mode option 2302, and the foldable screen mobile phone responds to the user's operation and displays a selfie mode selection pop-up window 2303, such as Fig.21 As shown in Figure (c).

[0248] The selfie mode selection pop-up window 2303 (also referred to as the first pop-up window) includes a rear selfie option 2313 and a front selfie option 2323. The rear selfie option 2313 is currently selected. The user can click the front selfie option 2323 to select the default use of the front camera for selfies. In response to the user's operation, the foldable screen mobile phone displays an interface 2304 (also referred to as the third photo preview interface), such as Fig.21 As shown in Figure (d).

[0249] Afterwards, the user closes the selfie mode selection pop-up window 2303 and exits the camera setting interface 2301. The foldable screen mobile phone responds to the user's operation and displays the photo preview interface 2304 on the main screen, such as Fig.21 The photo preview interface includes an image acquired by the rear camera and a flip camera control 909 , and an arrow mark 1902 may be displayed above the flip camera control 909 .

[0250] Optionally, the user can click the arrow mark 1902, or slide upward at the flip camera control 909, and the folding screen mobile phone responds to the user's operation and displays a capsule 2306 in the area where the flip camera control 909 is originally located, such as Fig.21 As shown in Figure (f) of Fig. 9 Similar to Figure (b) in the figure, capsule 2306 includes a rear selfie control 902 and a flip camera control 909. Unlike capsule 1903, the display positions of the rear selfie control 902 and the flip camera control 909 in the capsule are different. In capsule 1903, the rear selfie control 902 is displayed at the bottom, and the flip camera control 909 is displayed at the top. In this embodiment, in capsule 2306, the flip camera control 909 is displayed at the bottom, and the rear selfie control 902 is displayed at the top. That is to say, when the rear selfie control 902 is displayed by default in the photo preview interface, the user can slide up to add the flip camera control 909 to the interface; when the flip camera control 909 is displayed by default in the photo preview interface, the user can slide up to add the rear selfie control 902 to the interface.

[0251] If the user does not select a control in capsule 1903 after capsule 1903 is displayed for a preset time, that is, the user does not operate capsule 1903 within the preset time, capsule 1903 is hidden and the interface is restored to the photo preview interface 2304.

[0252] When the rear selfie function is continuously available, when the camera application is in the front selfie scene, the photo preview interface may further include a rear selfie control, so that the user can directly click on the rear selfie control to enter the rear selfie function.

[0253] For example, Fig. 22 This is another example of the interface change process of entering the rear Selfie function from the front Selfie scene provided by the embodiment of the present application. Fig. 22 As shown in FIG. 2 (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 2304. The photo preview interface 2304 includes an image obtained by the rear camera.

[0254] The photo preview interface 2304 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 is entered and a photo preview interface 2401 (also called a fourth photo preview interface) is displayed. The photo preview interface 2401 includes an image obtained by the front camera, such as Fig. 22 As shown in Figure (b) in the figure. In addition, the photo preview interface 2401 also includes a rear selfie control 2402 (also called a first control). Optionally, when the folding screen mobile phone detects that it is currently in a dark environment, a prompt message can be displayed in the rear selfie space 2402 to prompt the user to use the rear selfie function. Optionally, the prompt message can be displayed in the form of a bubble or the like for a preset duration. The content of the prompt message may, for example, be "Use the rear super-sensitive lens for selfies for better results".

[0255] The user clicks on the rear selfie control 2402 (also referred to as the first operation). 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. 22 As shown in Figure (c).

[0256] 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. 22 As shown in Figure (d).

[0257] In this embodiment, in the front-camera selfie scenario, the interface includes a rear-camera selfie control, and the user can directly click the control to enter the rear-camera selfie function, which facilitates user operation and improves user experience.

[0258] In another embodiment, when the rear selfie function is continuously available, the foldable 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 the following Fig. 22 In the photo preview interface 2304 shown in FIG. (a), the user can enter the setting control in the photo preview interface 2304 by clicking on the setting control in the photo preview interface 2304. Fig.21 The interface shown in Figure (b) is shown in Figure 1. After that, the user follows Fig.21 The user then closes the selection pop-up window 2303 and exits the camera setting interface 2301. The foldable screen mobile phone displays the flipping guidance interface 1105 on the main screen, as shown in FIG. Fig. 22 As shown in Figure (c) in the figure. 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. 22 As shown in Figure (d).

[0259] If the rear selfie function is still available, the user can Fig.13 or Fig.14 In the embodiment of the present invention, when the rear-mounted selfie function is entered through the desktop shortcut menu, in response to the user clicking the selfie option 1302 or the selfie shortcut icon 1401, the camera application is started and enters the corresponding photo preview interface according to the default selfie mode set by the user.

[0260] It can be understood that when the rear-camera selfie function continues to be available, the method of entering the rear-camera selfie function through other scenarios is the same or similar to the case where the user can set the rear-camera selfie function to be turned on and off, and will not be repeated here.

[0261] The above method provided by the present application is described by taking an external folding screen mobile phone as an example. In some other embodiments, the above method can also be applied to an internal folding screen mobile phone. The structure of the internal folding screen mobile phone is different from that of the external folding screen mobile phone. For example, Fig.23 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.23 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.23 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] like Fig.23 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.

[0266] Folding screen mobile phone 20 is in Fig.23 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.23 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.23 As shown in Figure (b).

[0267] 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.23 The folded state shown in Figure (c).

[0268] like Fig.23 As 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.

[0269] 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.

[0270] For example, Fig.24 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.24 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 2201. The photo preview interface 2201 includes a rear selfie control 902.

[0271] The user clicks on the rear selfie control 2202. In response to the user's operation, the folding screen mobile phone displays a flip guide interface 2203 through the first inner display screen and the second inner display screen. Fig.24 The content of the flip guide interface 2203 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 2213 is different.

[0272] After the flipping guide interface 2203 is displayed for a preset time (for example, 3 seconds), the camera application enters the rear selfie function. Specifically, the first inner display screen and the second inner display screen of the folding screen mobile phone are turned off, and the outer display screen is controlled to light up. At the same time, the image is acquired through the rear camera, and the photo preview interface 2204 is displayed through the external display screen. The photo preview interface 2204 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 2204, such as Fig.24 As shown in Figure (c).
