Description

Technical Field

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

[0002] Folding screen mobile phones include a main screen and a secondary screen. Figure 1 As shown in , the front camera 103 is located in the upper right corner of the main screen 101, as shown in Figure 2 As shown in , the rear camera 104 is located on the back of the main screen 101. The user can use the front camera 103 in combination with the main screen 101 or take a front-facing selfie with the front camera 103 when the main screen 101 and the auxiliary screen 102 are unfolded. Due to the consideration of the thinness of the folding screen mobile phone itself, the performance of the front camera 103 is lower than that of the rear camera 104, and thus the image taken by the front camera 103 is not as good as the image taken by the rear camera. Therefore, Figure 2 As shown in , in order to improve the effect of user selfies, the folding screen of the folding screen mobile phone 10 can be folded. At this time, the auxiliary screen 102 and the rear camera 104 can be faced to the user, and then the user can take rear-facing selfies based on the auxiliary screen 102 and the rear camera 104. At present, how to improve the user experience of users taking rear-facing selfies is a technical problem that needs to be solved urgently. Summary of the invention

[0016] In some real-time examples, based on the flash stepless adjustment control 113 in the rear selfie interface 1021, the user can gradually adjust the brightness (fill light intensity) of the flash by clicking or sliding the flash current intensity control 113. For example, the user can adjust the brightness of the flash from the lowest brightness to the highest brightness based on the flash stepless adjustment control 113; and the working current intensity of the flash corresponding to the brightness of the flash is gradually adjusted from the lowest current to the highest current. For example, the range from the lowest current to the highest current is 5-50mA. The user can select the target flash working current to be 5mA, so that the brightness of the flash can be the brightness corresponding to 5mA, and then the user can take pictures based on the brightness corresponding to 5mA.

[0052] The illustrative embodiments of the present application include, but are not limited to, a photographing method, an electronic device, and a readable storage medium.

[0053] It can be understood that the electronic device in the embodiments of the present application can be any electronic device with a rear selfie function, including but not limited to mobile phones (such as single-screen mobile phones, folding screen mobile phones (folding up and down, folding outward, folding inward)), wearable devices (such as smart watches, smart bracelets, etc.), tablet computers, desktops, laptops, handheld computers, notebook computers, netbooks, etc., and the embodiments of the present application are not limited. For the convenience of description, the following description takes the electronic device as an example of a folding screen mobile phone.

[0054] The technical solution of the present application is described below in conjunction with the accompanying drawings.

[0055] The following first explains the front selfie mode, conventional rear camera mode and rear selfie mode mentioned in this application.

[0056] like Figure 3A As shown, the front selfie mode refers to a mode for taking selfies using the main screen 101 and the front camera 103. The user can take a front selfie using the front camera 103 by clicking the photo control 1062 in the front selfie interface 1011 of the main screen 101. In some embodiments, the front selfie mode can also be based on taking a selfie with the front camera 103 when the main screen 101 and the auxiliary screen 102 are in the unfolded state.

[0057] The conventional rear camera mode refers to a mode for taking photos using the main screen 101 and the rear camera 104. The user can click Figure 3A The camera switch control 1061 in the front selfie interface 1011 makes the main screen 101 display as follows Figure 3B The rear camera interface 1012 is shown, Figure 3B As shown in , the user can use the rear camera 104 to take a rear photo by clicking the photo control 1062 in the rear photo interface 1012. It can be understood that the user can also return to the front selfie mode by clicking the photo switching control 1061.

[0058] The rear selfie mode refers to a mode for taking selfies using the secondary screen 102 and the rear camera 104. The user can click Figure 3A The secondary screen selfie control 107 in the secondary screen makes the secondary screen 102 display as follows Figure 3C The rear selfie interface 1021 shown, as Figure 3C As shown in , the user can take a rear selfie using the rear camera 104 by clicking the photo control 1062 in the rear selfie interface 1021 .

[0059] It can be understood that the front selfie mode, conventional rear camera mode and rear selfie mode mentioned in this application are just examples. When the configuration or design of the electronic device is different, the method of implementing the above modes may also be different. For example, a conventional single-screen mobile phone can also be provided with a secondary screen on the back of the phone to realize rear selfie.

[0060] It can be understood that the front selfie mode, conventional rear camera mode and rear selfie mode mentioned in this application include but are not limited to picture, video and other shooting modes. The following takes picture shooting as an example to illustrate the present application scheme.

[0061] In some embodiments, in the scenario of taking a selfie with the secondary screen 102 in combination with the rear camera 104, the focal length of the secondary screen selfie can directly use the focal length in the front selfie mode, such as 1x, or use the focal length in the conventional rear camera mode, such as 1x, 2x / 3x, 10x, 20x and other optional focal lengths. If the focal length of the secondary screen selfie uses the focal length in the front selfie mode, the focal length of the secondary screen selfie is too single and cannot meet the secondary screen selfie needs in many user scenarios; if the focal length of the secondary screen selfie uses the focal length in the conventional rear camera mode, since the focal length in the conventional rear camera mode is set based on the needs of rear camera photography, it is generally a larger focal length for shooting scenery, etc., so it is difficult to meet the user's selfie needs. For example, when taking selfies, users prefer a smaller focal length to make the face ratio smaller, that is, the focal length configuration in the rear camera mode is not suitable for user selfies.

[0062] In order to solve the above problems, an embodiment of the present application provides a method for taking pictures. The method includes: configuring a separate focal length group for the secondary screen selfie to meet the needs of the secondary screen selfie, for example, configuring a group of smaller focal lengths (for example, 0.6x or wide angle / 0.8x / 1x / 1.3x), and then being able to meet the needs of the user for a smaller face and thinner appearance in the selfie image based on a smaller wide angle. When the user is taking a picture, the electronic device can directly determine the current shooting mode, and select and display the focal length group based on the current shooting mode. For example, when it is detected that the user is taking a rear selfie, the focal length group corresponding to the rear selfie is displayed on the secondary screen so that the user can select a suitable focal length. In this way, there is no need to reuse the focal lengths in the front selfie mode and the conventional rear camera mode, which meets the user's needs for rear selfies and improves the user experience.

[0063] It can be understood that in some embodiments, in the rear selfie mode, the default main camera focal length can be adjusted to other focal lengths, for example, the main camera focal length can be adjusted from 1x to 0.6x, so that the wide-angle focal length can include 0.4x. For example, in the rear selfie mode, a set of smaller focal lengths (0.4x / 0.6x / 1x / 1.3x) can be configured.

[0064] In some embodiments, the focal length of the current rear wide-angle camera can be calculated based on the physical focal length of the rear main camera, the default focal length of the rear main camera, and the physical focal length of the rear wide-angle camera. For example, the focal length of the rear main camera can be adjusted from 1x to 0.6x, and the wide-angle focal length is calculated based on the 0.6x main camera focal length, the physical focal length of the main camera 25.1mm, and the physical focal length of the wide-angle camera 15.8mm: 15.80.63x*15.8 / 25.1=0.39x≈0.4x, so the current focal length of the rear wide-angle camera is 0.4x.

[0065] It can be understood that 0.6x and 0.4x can be called an ultra-wide-angle focal length, and the main camera focal length can refer to the focal length corresponding to the wide-angle camera.

[0066] It is understandable that in other shooting modes, the default main camera focal length can also be adjusted to other focal lengths, such as 0.6x focal length, and this application does not limit this.

[0067] In some embodiments, the separate focus group configured for the secondary screen selfie can support user click selection, or slide selection. Figure 4A The rear-camera selfie interface 1021 shown includes a focal length selection control group 105. The focal length selection control group 105 may include multiple focal length controls, each focal length control corresponding to a focal length. For example, the focal length group corresponding to the focal length selection control group 105 may be (0.6x / 0.8x / 1x / 1.3x). The user can take a rear-camera selfie by clicking any focal length control in the above focal length selection control group 105 (for example, clicking to select a 1x focal length control) to obtain an image taken at the corresponding focal length.

[0068] Another example Figure 4B The rear-camera selfie interface 1021 shown includes a focal length sliding control group 106, which may include multiple focal length controls, each focal length control corresponding to a focal length. For example, the focal length group corresponding to the focal length sliding control group 106 may be (0.6x-1x-1.3x). The user may also slide to select any focal length in the focal length sliding control group 106 (for example, slide to select a 1x focal length control) to take a rear-camera selfie, and obtain an image taken with the corresponding focal length.

[0069] In addition, in the secondary screen selfie mode of the foldable screen mobile phone 10, since the flash brightness is too high, using the rear flash when taking selfies with the secondary screen will affect the user's eye health. Therefore, in some embodiments, when taking selfies with the secondary screen, the flash is generally not used, and only the ring fill light is used to provide fill light for the secondary screen selfie. For example Figure 5A schematic diagram of a rear-camera selfie based on a ring fill light is shown. The automatic ring fill light control 108 in the rear-camera selfie interface 1021 is in the default on state. It can be seen that the outer area of ​​the image part in the rear-camera selfie interface 1021, that is, the area 109 outside the dotted line can be displayed as a translucent area, that is, the ring fill light is displayed in this area, and the flash control 110 is in the off state, that is, in the secondary screen selfie mode of the folding screen mobile phone 10, the flash of the rear camera is not used to assist the secondary screen selfie.

[0070] However, the above-mentioned rear selfie method based only on annular fill light will result in too low shooting brightness, affecting the image effect.

[0071] Based on this, in some embodiments of the present application, when taking a selfie with the secondary screen in the rear selfie mode, the normal working current of the flash can be set to be reduced, that is, a smaller working current of the flash is set so that the flash is in a low-power state, for example, the working current of the flash in the low-power state can be 5-50mA, and in the normal rear camera mode, the normal working current of the flash is set so that the flash is in a high-power state, for example, the working current of the flash in the high-power state can be 100mA. In this way, using the flash to fill in light when taking a selfie with the rear camera can meet both the user's eye protection needs and the camera brightness needs.

[0072] The specific process of the photo taking method provided by this application is described below.

[0073] refer to Figure 6 , Figure 6 A specific process diagram of a method for taking a photo is shown. The method can be performed by an electronic device. For ease of understanding, the electronic device is a folding screen mobile phone 10 as an example for explanation, and the specific process includes:

[0074] S101: Detecting an operation of a user triggering a rear-camera selfie mode, and starting the rear-camera selfie mode.

[0075] In some embodiments, the operation of triggering the rear selfie mode can be an operation of detecting that a user triggers a corresponding rear selfie mode control (such as the secondary screen camera control mentioned in this application), or it can be any other operation that can trigger the rear selfie mode, such as a corresponding voice command.

[0076] For example, Fig. 7A and Figure 7B A schematic diagram showing a foldable screen mobile phone 10 switching from a front selfie mode to a rear selfie mode. Fig. 7A A schematic diagram of the front selfie interface 1011 of the foldable screen mobile phone 10 in the front selfie mode is shown. When it is detected that the user clicks Fig. 7AWhen the secondary screen camera control 107 in the front selfie interface 1011 is displayed, the secondary screen 102 of the folding screen mobile phone 10 is displayed as follows: Figure 7B The rear selfie interface 1021 shown in the figure indicates that the current folding screen mobile phone 10 is in the secondary screen selfie mode.

[0077] It can be understood that in some embodiments, when it is necessary to switch from the conventional rear-camera camera mode to the rear-camera selfie mode, the conventional rear-camera camera mode can be switched to the front-camera selfie mode first, and then the front-camera selfie mode can be switched to the rear-camera selfie mode by clicking the secondary-screen camera control 107 in the front-camera selfie interface 1011 in the front-camera selfie mode to take a secondary-screen selfie.

[0078] It is understood that in some embodiments, Fig. 7A As shown, when the folding screen mobile phone 10 is in the front selfie mode, when the user clicks the secondary screen camera control 107 in the front selfie interface 1011, the front selfie interface 1011 will display the following Figure 7C The interface shown in the figure prompts the user to flip the foldable screen mobile phone 10. After the user flips the foldable screen mobile phone 10, the foldable screen mobile phone 10 responds to the flipping operation, turns on the rear camera, that is, turns on the rear selfie mode, and displays the following on the secondary screen 102: Figure 7B The rear selfie interface 1021 shown in FIG. In this way, when the user uses the secondary screen to take a selfie, the user can directly use the rear selfie mode to take a selfie.

[0079] It can be understood that in the front-facing selfie mode, when the user clicks on the secondary screen camera control 107 in the front-facing selfie interface 1011, the foldable screen mobile phone 10 can directly switch to the rear-facing selfie mode; or when the user clicks on the secondary screen camera control 107 in the front-facing selfie interface 1011, the user can be prompted in the front-facing selfie interface 1011 to flip the foldable screen mobile phone 10, and then the foldable screen mobile phone 10 switches to the rear-facing selfie mode, which is not limited here.

[0080] S102: Displaying the focal length group corresponding to the secondary screen selfie interface.

[0081] It can be understood that the secondary screen selfie interface is also the rear selfie interface 1021.

[0082] In some embodiments, as described above Figure 4A and Figure 4B As shown, the focal length group corresponding to the secondary screen selfie can be displayed on the rear selfie interface 1021. For example, the focal length group in the rear selfie mode can be (0.6x / 0.8x / 1x / 1.3x).

[0083] In some embodiments, the focus group in the rear selfie mode can support the user to select by clicking, or sliding to select. Figure 4AThe rear Selfie interface 1021 shown includes a focal length selection control group 105, and the focal length group of the focal length selection control group 105 can be (0.6x / 0.8x / 1x / 1.3x). Then the user can click on any focal length in the above focal length group (for example, 1x focal length) to take a rear Selfie, and can obtain an image taken with the corresponding focal length. Figure 4B In the rear selfie interface 1021 shown, the user can also slide to select any focal length (such as 1x focal length) in the focal length sliding control group 106 to take a rear selfie, and obtain an image taken with the corresponding focal length.

[0084] S103: Obtain the shooting focal length selected by the user from the secondary screen selfie focal length group, and capture an image based on the user's shooting instruction.

[0085] In some embodiments, the user can click Figure 4A The focal length selection control group 105 shown in FIG. 1 can be used to select the focal length for the secondary screen Selfie, or the focal length can be selected by sliding as shown in FIG. Figure 4B The focus range sliding control group 106 shown in the figure selects the shooting focus range of the secondary screen Selfie. Figure 4A Or as shown in FIG4B, based on the shooting instruction generated by the user clicking the shooting control 1062. The folding screen mobile phone 10 can take a selfie according to the shooting focal length of the secondary screen selfie selected by the user.

[0086] It is understood that in some embodiments, in the rear selfie mode, the default focal length of the rear main camera can be defined as 0.6x focal length, so that the wide-angle focal length can include 0.4x. For example, in the rear selfie mode, a set of smaller focal lengths (0.4x / 0.6x / 1x / 1.3x) can be configured. In some embodiments, the default focal length of the rear main camera can also be defined as other focal lengths.

[0087] The principle of achieving a wide-angle focal length of 0.4x is explained below.

[0088] It can be understood that the fixed physical focal length of the rear main camera based on the rear camera is generally 25.1mm. When the default rear main camera focal length is defined as 0.6x focal length, since the fixed physical focal length of the rear wide angle of the rear camera 104 is 15.8mm, when 0.6x is calculated as the focal length of the rear main camera based on the fixed physical focal length of the rear main camera 25.1mm, the defined 0.6x focal length of the rear main camera and the default fixed physical focal length of the rear wide angle 15.8mm, the focal length of the rear wide angle is 0.63x*15.8 / 25.1=0.39x≈0.4x.

[0089] It can be understood that in other embodiments, in the front-facing selfie mode, the front-facing selfie focal length can be set to include 0.4x; or, in the conventional rear-facing camera mode, the front-facing selfie focal length can be set to include 0.4x, which is not limited here.

[0090] It can be understood that the field of view corresponding to the image captured based on the wide-angle focal length of 0.4x is greater than or equal to the first field of view angle threshold value. The field of view corresponding to the wide-angle focal length of 0.4x provided in the embodiment of the present application can be a field of view greater than or equal to 110°. For example, the field of view corresponding to the wide-angle focal length of 0.4x can also be 112°, 115°, etc., which are not limited here. The field of view when taking a selfie with the secondary screen based on the wide-angle focal length of 0.4x is larger, which can enable users to have a better selfie experience. However, if in the secondary screen selfie scene, the wide-angle focal length of 0.6x in the rear camera mode is used, and the field of view angle corresponding to the 0.6x focal length is less than the first field of view angle threshold value, for example, the field of view angle corresponding to the 0.6x focal length is 100°, then the field of view angle of the image captured based on the 0.6x focal length is too small, affecting the user's secondary screen selfie experience.

[0091] In some embodiments, the focal length group in the rear selfie mode can be (0.4x-0.6x-1x-10x). Among them, the physical focal length corresponding to the 0.5x focal length between the 0.4x focal length and the 0.6x focal length can be digitally cropped based on the 0.4x wide-angle focal length, that is, the physical focal length corresponding to the 0.5x focal length is 0.5x / 0.4x*15.8=19.75mm. In addition, the focal length between the 0.7x focal length and the 10x focal length can be digitally cropped based on the 0.6x main focal length. For example, the physical focal length corresponding to the 1x focal length is 1x / 0.6x*25.1=39.5mm.

[0092] Further, refer to Figure 8 , Figure 8 A specific process diagram of a method for taking a photo is shown. The method can be performed by an electronic device. For ease of understanding, the electronic device is a folding screen mobile phone 10 as an example for explanation, and the specific process includes:

[0093] S201: Detect the current shooting mode of the electronic device.

[0094] In some embodiments, the foldable screen mobile phone 10 can directly determine the current shooting mode of the foldable screen mobile phone 10 based on the status of the controls in the current photo-taking interface of the foldable screen mobile phone 10 and the status of the corresponding camera.

[0095] For example, it can be determined that the current shooting mode of the foldable screen mobile phone is in the rear selfie mode based on the secondary screen photo control 107 being in the turned-on state and the turned-on state of the rear camera.

[0096] For example, it can be determined that the current shooting mode of the foldable screen mobile phone is in the rear camera mode based on the secondary screen camera control 107 being in the closed state and the rear camera being in the opened state.

[0097] For example, it can be determined that the current shooting mode of the foldable screen mobile phone is in the front selfie mode based on the secondary screen photo control 107 being in the closed state and the front camera being in the opened state.

[0098] S202: Determine that the electronic device is in a rear-mounted selfie mode.

[0099] S203: Detecting a flash light on command and a rear-camera selfie command, and performing a rear-camera selfie based on the first flash light configuration scheme.

[0100] In some embodiments, in the rear selfie mode of the folding screen mobile phone 10, the flash light on instruction may be as follows: Fig. 9B As shown, the user clicks on the super fill light activation control 112 in the rear selfie interface 1021 in the secondary screen 102 to generate an instruction.

[0101] For example Fig.9A In the rear Selfie interface 1021 shown, the user turns on the flash function by clicking the flash control 110 in the rear Selfie interface 1021. Fig. 9B The rear selfie interface 1021 shown displays an automatic ring fill light control 108 (enabled by default), a flash control 110 (both the ring fill light and the flash are disabled), a forced ring fill light control 111, and a super fill light enable control 112. The user can click the super fill light enable control 112 to enable the foldable screen mobile phone 10 to configure the flash based on the first flash configuration scheme.

[0102] Among them, the first flash configuration scheme refers to reducing the operating current of the conventional flash in the rear selfie mode, for example, the operating current of the flash can be set to 5-50mA to make the flash in a low power state. In this way, a weaker flash fill light intensity that can protect the eyes can be provided to the subject in the rear selfie scene. Finally, based on the shooting instruction generated by the user clicking the shooting control 1062, the folding screen mobile phone 10 can take a selfie based on the shooting focal length of the secondary screen selfie selected by the user and the configuration scheme of the first flash.

[0103] It can be understood that in other embodiments, when the foldable screen mobile phone 10 is in the rear selfie mode, when the user clicks the shooting control 1062, the super fill light on control 112 in the flash control 110 can be in an automatically turned on state, so that when the shooting instruction generated by the user clicking the shooting control 1062 is received, the flash is turned on by default to assist the user in taking selfies, without the user having to turn on the flash by clicking the super fill light on control 112.

[0104] It is understandable that Fig.9A and Fig. 9B In the rear selfie interface 1021 in the secondary screen 102 shown, the instruction generated by the user clicking the shooting control 1062 can be used as a rear selfie instruction. This is just an example. In some embodiments, the voice control instruction of the user through voice control shooting can also be a rear selfie instruction, which is not limited here.

[0105] In some embodiments, a flash current intensity control that can be slid to adjust the flash current intensity can also be displayed in the rear selfie interface 1021, for example Fig. 9C In the rear selfie interface 1021 shown, after the user clicks on the super fill light to turn on the control 112, the flash stepless adjustment control 113 is displayed in the rear selfie interface 1021. The user can adjust the brightness of the flash from the lowest brightness to the highest brightness based on the flash stepless adjustment control 113, that is, the corresponding working current intensity of the flash is gradually adjusted from the lowest current to the highest current. For example, the range from the lowest current to the highest current is 5-50mA, and the current adjustment unit can be 1mA, so that the user can gradually adjust the brightness of the flash (fill light intensity) by clicking or sliding the flash current intensity control 113.

[0106] Based on this, the fill light intensity of the flash can be set to be variable, so that users can flexibly adjust the fill light intensity of the flash based on their own selfie needs, thereby allowing users to have a good photo-taking experience.

[0107] S204: Determine whether the electronic device is in a normal rear-facing camera mode.

[0108] S205: Detecting a flash light on instruction and a post-photographing instruction, and taking a photo based on a second flash light configuration scheme.

[0109] In some embodiments, in the conventional rear camera mode of the foldable screen mobile phone 10, for example Fig.9D In the rear camera interface 1012 displayed in the main screen 101 shown, based on the flash on instruction generated by the user clicking the flash control 110, the folding screen mobile phone 10 can configure the flash according to the second flash configuration scheme. Among them, the second flash configuration scheme refers to setting the operating current of the conventional flash in the conventional rear camera mode so that the flash is in a high-power state. For example, the operating current of the flash in the high-power state can be 100mA. Further, based on the rear selfie instruction generated by the user clicking the shooting control 1062, the folding screen mobile phone 10 can shoot according to the second flash configuration scheme. In turn, a stronger flash fill light intensity can be provided for the subject in the rear camera scene.

[0110] It can be understood that the execution order of the above steps S202-S203 and steps S204-S205 can be swapped, and no limitation is made here.

[0111] Through the photographing method provided in the embodiment of the present application, different flash configuration schemes can be provided for folding screen mobile phones in different shooting modes, so that in different shooting modes, different intensities of fill light can be provided to the photographed subject based on different flash configuration schemes to assist in taking pictures, thereby improving the clarity of the captured image and improving the user's shooting experience.

[0112] Further, refer to Fig.10 , Fig.10 A specific process diagram of a method for taking a photo is shown. The method can be performed by an electronic device. For ease of understanding, the electronic device is a folding screen mobile phone 10 as an example for explanation, and the specific process includes:

[0113] S301: Detecting an instruction from a user to trigger a rear-camera selfie mode, and starting the rear-camera selfie mode.

[0114] In some embodiments, the process of step S301 may refer to the above-mentioned step S101 and will not be repeated here.

[0115] S302: Displaying the focal length group corresponding to the secondary screen selfie interface.

[0116] In some embodiments, the process of step S301 may refer to the above-mentioned step S102 and will not be repeated here.

[0117] S303: Obtain the shooting focal length selected by the user from the secondary screen selfie focal length group, and based on the user's shooting instruction and the flash on instruction, use the first flash configuration scheme to shoot an image.

[0118] In some embodiments, first, the user can click on e.g. Figure 4A The focal length selection control group 105 shown in FIG. 1 is used to select the focal length for the secondary screen Selfie, or the focal length can be selected by sliding, for example Figure 4B The focal length sliding control group 106 shown in the figure selects the shooting focal length for the secondary screen Selfie.

[0119] Further, the user can click on the Fig.9A The flash control 110 in the rear selfie interface 1021 shown turns on the flash function.

[0120] Based on the user clicking the flash control 110, such as Fig. 9BThe rear selfie interface 1021 shown displays an automatic ring fill light control 108 (enabled by default), a flash control 110 (both the ring fill light and the flash are disabled), a forced ring fill light control 111, and a super fill light enable control 112. The user can click the super fill light enable control 112 to enable the foldable screen mobile phone 10 to configure the flash based on the first flash configuration scheme.

[0121] Finally, based on the shooting instruction generated by the user clicking the shooting control 1062, the foldable screen mobile phone 10 can take a selfie based on the shooting focal length of the secondary screen selfie and the configuration scheme of the first flash selected by the user.

[0122] It can be understood that in other embodiments, when the foldable screen mobile phone 10 is in the rear selfie mode, when the user clicks the shooting control 1062, the super fill light on control 112 in the flash control 110 can be in an automatically turned on state, so that when the shooting instruction generated by the user clicking the shooting control 1062 is received, the flash is turned on by default to assist the user in taking selfies, without the user having to turn on the flash by clicking the super fill light on control 112.

[0123] Through the photographing method provided in the embodiment of the present application, different shooting focal length groups can be provided for different shooting modes of the folding screen mobile phone, so that the user can select the appropriate shooting focal length in different shooting focal length groups for shooting in different shooting modes based on their own shooting needs. In this way, the user's needs for post-selfie can be met and the user experience can be improved.

[0124] In addition, the photographing method provided in the embodiment of the present application can provide different flash configuration schemes for folding screen mobile phones in different shooting modes, so that in different shooting modes, different intensities of fill light can be provided to the photographed subject based on different flash configuration schemes to assist in taking pictures, thereby improving the clarity of the captured image and improving the user's shooting experience.
