When the "function open" control 231 is in the off state, the user can open the quick photographing function of the camera application by operating the "function open" control 231.

As shown in fig. 4 (c), the "function open" control 231 is in an off state. When the user clicks or slides the "function on" control 231, in response to the user operation, the electronic device jumps to the setup interface 24 as shown in fig. 4 (d). In the setting interface 24, the "function open" control 231 is in an open state, which indicates that the electronic device has opened the quick capture function of the camera application.

It will be appreciated that the quick shoot function may be turned on by default or turned off by default. For example, when the quick photographing function is turned on by default, the user opens the setting interface 23 shown in (c) in fig. 4 for the first time, and the "function on" control 231 in the setting interface 23 is in an on state. When the quick photographing function is turned off by default, the user opens the setting interface 23 shown in (c) in fig. 4 for the first time, and the "function on" control 231 in the setting interface 23 is in the off state.

When the quick photographing function is in an on state, a user can set photographing parameters required for the quick photographing function.

Continuing with the example of FIG. 4, when the "function on" control 231 in the setup interface 23 is in an on state, a "fingerprint list" is displayed in the setup interface 24, the "fingerprint list" including fingerprints that have been entered on the current electronic device. As shown in fig. 4 (d), 5 fingerprints that have been entered are included in the "fingerprint list".

The user can set shooting parameters for fingerprints already recorded on the electronic device so as to establish a corresponding relation between fingerprint information and the shooting parameters. As shown in (d) of fig. 4, the user clicks the setting button 241 corresponding to "fingerprint 5", and in response to the user operation, the electronic apparatus jumps to the setting interface 25 shown in (e) of fig. 4. As shown in (e) of fig. 4, the setting interface 25 includes a setting window 251 in which an input box 2511 of photographing parameters can be displayed, and a user can input parameter values within the input box 2511. As shown in (e) of fig. 4, a "ZOOM" magnification, "AF," and an automatic exposure time "S" or the like may be included in the input frame 2511. When the user operates the "save" control 2512 in the setting window 251, in response to the user operation, the electronic device saves the correspondence between the fingerprint information of "fingerprint 5" and the parameter value within the input box 2511, and jumps back to the setting interface 24 as shown in (d) of fig. 4. When the user operates the "delete" control 2513 in the setting window 251, in response to the user operation, the electronic device deletes the correspondence between the saved fingerprint information of "fingerprint 5" and the parameter values within the input box 2511, and deletes "fingerprint 5" from the "fingerprint list" and jumps to the setting interface 26 as shown in fig. 4 (f).

In some examples, when the user sets a shooting parameter for a certain fingerprint for the first time, the input box 2511 in the setting window 251 may be empty, or a default value may be displayed.

In some examples, for an unset fingerprint, the shooting parameter corresponding to the fingerprint may be set to a default value.

In another implementation of setting the quick capture function, the user may set the quick capture function through a setup application portal of the electronic device.

As another example of the setting manner, referring to fig. 5, a schematic diagram of a setting procedure of the quick photographing function provided in another embodiment of the present application is shown. As shown in fig. 5 (a), for the desktop 31 of the electronic device, the user clicks an icon 311 of the setting application on the desktop 31, and in response to the user operation, the electronic device jumps to the setting interface 32 as shown in fig. 5 (b). The user clicks the "auxiliary function" control 321 in the setting interface 32, and in response to this user operation, the electronic device jumps to the setting interface 33 as shown in (c) in fig. 5. The user clicks the "quick start and gesture" control 331 in the setup interface 33, and in response to this user operation, the electronic device jumps to the setup interface 34 as shown in fig. 5 (d). The user clicks the "quick shoot" control 341 in the setting interface 34, and in response to this user operation, the electronic apparatus jumps to the setting interface 35 as shown in (e) in fig. 5.

The setup interface 35 includes a "function open" control 351. The user can turn on or off the quick photographing function of the camera application by operating the "function on" control 351. For example, when the "function open" control 351 is in an open state, the user can close the quick capture function of the camera application by operating (e.g., clicking or sliding, etc.) the "function open" control 551. When the "function on" control 351 is in an off state, the user can start the quick photographing function of the camera application by operating the "function on" control 351.

As shown in fig. 5 (e), the "function open" control 351 is in an off state. When the user clicks or slides the "function on" control 351, in response to the user operation, the electronic device jumps to the setting interface 36 as shown in fig. 5 (f). In the setting interface 36, the "function on" control 351 is in an on state, indicating that the electronic device has opened the quick capture function of the camera application. When the quick photographing function is in an on state, a user can set photographing parameters required for the quick photographing function. The setting manner of the shooting parameters can be referred to the description in the embodiments (d) - (f) in fig. 4, and will not be described herein.

It should be noted that, the on state of the quick shooting function in the setting application is consistent with the on state of the quick shooting function in the camera application. For example, if the user turns on the quick shoot function through the "setup" portal in the camera application, the quick shoot function in the setup application is also turned on. If the user turns off the quick photographing function by setting the application portal, the quick photographing function in the camera application becomes a turned-off state.

In some examples, as shown in (d) of fig. 5, when the user operates the "quick shoot" control 341 in the setting interface 34, in response to the user operation, the electronic device may jump to the setting interface for quick shoot in the camera application, for example, to the setting interface 23 shown in (c) of fig. 4. The user then sets shooting parameters involved in the quick shooting function in a setting interface of the camera application.

As shown in the embodiments of fig. 4 and 5, the electronic device may provide a variety of setup portals for the quick capture function. It should be noted that, in the above embodiments, only several possible setting manners are shown, and as an example, the setting entrance and the setting manner of the quick shooting function in the embodiments of the present application are not specifically limited. It should be noted that, the setting results (including fingerprint information and corresponding shooting parameters) of various setting entries of the quick shooting function in the electronic device remain consistent.

In some application scenarios, a user needs to add fingerprint information and corresponding shooting parameters. In one implementation, fingerprint information may be added through a "setup" portal of the camera application. For example, taking fig. 4 as an example, in the setting interface 24 shown in (d) in fig. 4, the user can add fingerprint information by operating the "newly added fingerprint" control. In another implementation, the fingerprint information may be newly added through a setup application portal of the electronic device. For example, taking fig. 5 as an example, in the setting interface 32 shown in (b) in fig. 5, the user can enter the setting interface of "biometric and password" by operating the "biometric and password" control, and perform a user operation on the setting interface to add fingerprint information. In another implementation, in the "setting" of the camera application, a "newly added fingerprint" control is provided, and when the user operates the "newly added fingerprint" control, the electronic device jumps to a setting interface of "biometric identification and password" in the setting application, so that the user adds fingerprint information in the setting interface.

As an example of adding fingerprint information, referring to fig. 6, a schematic diagram of a setting procedure of an added fingerprint provided in the embodiment of the present application is shown. As shown in fig. 6 (a), the setting interface 24 in the embodiment of fig. 4, that is, the interface for setting the quick photographing function in the "setting" of the camera application is shown. The setup interface 24 may provide access to the newly added fingerprint. As shown in fig. 6 (a), when the user operates the "new fingerprint" control 242 on the setting interface 24, in response to the user operation, the electronic device jumps to the setting interface 41 shown in fig. 6 (b), and the setting interface 41 is a setting interface of "biometric identification and password" in the setting application of the electronic device. The user adds fingerprint information in a setup application of the electronic device. As shown in fig. 6 (b), when the user operates the "fingerprint" control 411, in response to the user operation, the electronic device jumps to the setting interface 42 shown in fig. 6 (c). In the device interface 42 a "fingerprint list" is displayed, which includes the currently entered fingerprint.

It will be appreciated that the fingerprint information contained in the "fingerprint list" of each application in the electronic device remains consistent. For example, the fingerprint included in the "fingerprint list" in the setting interface 42, the fingerprint included in the "fingerprint list" on the setting page of the quick photographing function in the camera application (as shown in fig. 6 (a)), and the fingerprint included in the "fingerprint list" on the setting page of the quick photographing function in the setting application (as shown in fig. 5 (f)) are kept identical.

Continuing with the example of FIG. 6, when the user operates a "New fingerprint" control 421 in the setup interface 42, in response to the user operation, the electronic device jumps to the setup interface 43 as shown in FIG. 6 (d). And the user performs fingerprint input according to the prompt information in the interface. For example, when the user operates the "start entry" control 431 in the setting interface 43, in response to the user operation, the electronic device displays a prompt box of the fingerprint sensing area, the user presses a finger in the prompt box, and the electronic device acquires fingerprint information of the user. When the fingerprint entry is successful, the electronic device displays a setup interface 44 as shown in fig. 6 (e). When the user operates the "done" control 441 in the setting interface 44, in response to the user operation, the electronic device holds the fingerprint information that has just been entered, updates the "fingerprint list" of the respective applications in the electronic device, and jumps to the setting interface 45 as shown in (f) in fig. 6. The setting interface 45 is an interface for setting the quick photographing function in the "setting" of the camera application. As shown in the setting interface 45, a "fingerprint 6" is added to the "fingerprint list" of the camera application, that is, the name of the fingerprint information that has just been entered. The user may continue to set shooting parameters for the newly added fingerprint in the setting interface of the quick shooting function of the camera application.

4-6, through interaction between a user and the electronic device, the electronic device correlates fingerprint information selected by the user with shooting parameters input by the user according to user operation, so as to obtain a corresponding relationship between at least one group of fingerprint information and shooting parameters, and stores the corresponding relationship. When the step of the photographing method is executed later, the electronic device can process according to the corresponding relation between the stored fingerprint information and the photographing parameters so as to realize the rapid photographing function.

In some implementations, the electronic device may generate a preset relationship table including at least one set of relationship data, each set of relationship data including a set of fingerprint information and a set of shooting parameters.

In some implementations, the electronic device may correlate the face image, the fingerprint information, and the shooting parameters. For example, the preset relationship table includes at least one set of relationship data, and each set of relationship data includes a face image, a set of fingerprint information and a set of shooting parameters.

Based on the setting of the quick shooting function, when the quick shooting function is in an on state, a user can quickly start a camera application in the electronic equipment to shoot under the condition that the electronic equipment is in a standby state. The shooting method provided by the embodiment of the present application is described below. Referring to fig. 7, a flowchart of a photographing method provided in an embodiment of the present application is shown. By way of example and not limitation, as shown in fig. 7, the photographing method may include the steps of:

S701, detecting a first operation of a user when the electronic equipment is in a screen locking state, wherein the first operation is used for triggering face recognition.

The screen locking state can be a screen locking state of screen extinction or a screen locking state of screen brightness. The screen-lighting and screen-locking state indicates that the touch display screen is lightened, so that information such as date and time can be displayed, but the display interface does not display a main application interface or other application program interfaces. For example, after a switch key of a mobile phone is pressed, a touch display screen of the mobile phone will be lightened, but a user wants to use the mobile phone and needs to perform an unlocking operation to access a main application interface or other application program interfaces of the mobile phone.

It should be noted that, in some application scenarios, when the electronic device is in a standby state, the screen of the electronic device may also be in a locked state. Therefore, in the embodiments of the present application, as long as the screen of the electronic device is in a locked state (i.e., the main application interface or other application interfaces of the electronic device may be operated only when unlocking is required), the electronic device may be said to be in a screen-locked state.

S702, responding to the first operation, starting face recognition to obtain a first recognition result.

In some implementations, when the first operation is detected, a front camera in the electronic device acquires a face image, and face recognition is performed according to the face image to obtain a first recognition result. If the face image is matched with the face image stored in the electronic equipment in advance, the first recognition result indicates that the face recognition passes; if the face image is not matched with the face image stored in the electronic equipment in advance, the first recognition result indicates that the face recognition is failed.

In some implementations, if the first recognition result indicates that the face recognition fails, the face recognition is performed again.

And S703, if the first recognition result indicates that the face recognition passes, detecting a second operation of the user, wherein the second operation is used for triggering fingerprint recognition.

If the second operation is not detected, the current user does not need to take a picture quickly and only needs to take a normal unlocking screen, and a fourth interface is displayed, wherein the fourth interface is an interface of a desktop application of the electronic equipment.

In some implementations, the second operation by the user may include the user contacting the display screen. Specifically, if the display screen of the electronic device is a capacitive screen, the electronic device may determine whether the user touches the display screen according to the capacitive signal of the display screen. For example, for a self-capacitive touch display screen, after a user touches the screen, the capacitance value of the touch area increases; in the case of a mutual capacitive touch display, the capacitance of the touch area decreases after the user touches the screen. The electronic device can judge whether the user touches the display screen according to the change of the capacitance value.

In other implementations, the second operation by the user may include the user contacting a predetermined area on the display screen. For example, in order to save electric power, when the electronic device locks the screen, only a partial area of the display screen may be scanned and detected, that is, the area where the scanning and detection are performed may be identified as an operation of the user, while other areas are in a non-working state and cannot detect the operation of the user. The area for scanning detection may be an area including fingerprint recognition, for example, if the fingerprint detector is disposed in the lower half area of the display screen, only the lower half area of the display screen may be scanned and detected when the screen is locked.

It will be appreciated that the above-mentioned division of the area is only an example, and the preset area may be set according to different scenes and different user requirements in actual application.

In some implementations, after the face recognition is passed, the fingerprint identification may be displayed in a preset area (i.e., a fingerprint identification area) of the display screen, so as to indicate that the user performs the second operation. In other implementations, after the first operation is detected, the fingerprint identification identifier is displayed in a preset area of the display screen, so that the user can perform the second operation while performing face recognition, which is beneficial to saving recognition time.

And S704, responding to the second operation, starting fingerprint identification, and obtaining a second identification result.

In some implementations, when the second operation is monitored, the electronic device obtains first fingerprint information of the user through a sensor under the display screen, performs fingerprint identification according to the first fingerprint information, and obtains a second identification result. If the first fingerprint information is matched with the fingerprint information stored in the electronic equipment in advance, the second recognition result indicates that the fingerprint recognition is passed; if the first fingerprint information is not matched with the fingerprint information stored in the electronic equipment in advance, the second recognition result indicates that the fingerprint recognition is failed.

And S705, if the second recognition result indicates that the fingerprint recognition is passed, starting a camera application, and displaying a first interface, wherein the first interface is an interface of a shooting mode of the camera application.

And if the second recognition result indicates that the fingerprint recognition is not passed, indicating that the user does not set a quick shooting function for the current fingerprint information, displaying a third interface, wherein the third interface is an interface of desktop application of the electronic equipment.

In some embodiments, the processes of face recognition and fingerprint recognition in S702-S704 described above may be out of order.

S706, detecting a third operation of the user on the first interface.

The third operation is used for triggering shooting of the electronic equipment. The third operation by the user may include clicking a capture control on the first interface, double clicking a screen, double clicking an electronic device backplate, and so forth.

S707, in response to the third operation, shooting to obtain a first photo.

Exemplary, referring to fig. 8, a schematic diagram of a shooting procedure provided in an embodiment of the present application is shown. As shown in fig. 8 (a), the screen lock interface 51 of the electronic device is shown, and the electronic device is in a screen lock state. When the user performs a first operation (e.g., the user picks up the cell phone, presses a power key, operates on a screen (clicks, slides, etc.), pulls out a charging wire, etc.), the electronic device activates face recognition in response to the first operation, displaying a recognition interface 52 as shown in (b) of fig. 8. The identification interface 52 may include an identification of face recognition (e.g., the "face ID" shown in fig. 8 (b)) to indicate to the user that face recognition is currently being performed. An identification 501 of the fingerprint identification area may also be included in the identification interface 52 to prompt the user to enter fingerprint information. In case a second operation of the user is detected (e.g. the user's finger presses the identification 501 of the fingerprint identification area), the electronic device may perform face recognition and fingerprint identification in sequence. When the face recognition passes and the fingerprint recognition passes, the electronic device jumps to the photographing interface 53 as shown in (c) of fig. 8. The electronic equipment starts the camera application after unlocking the screen and jumps to the shooting interface of the camera application. When the user performs a third operation (e.g., clicks on the capture control 502, double clicks on a screen, double clicks on a back panel of the electronic device, etc.), the electronic device captures a first photograph in response to the third operation. As shown in fig. 8 (d), the photographing interface 54 displays a first photograph in a preview box 503.

As shown in fig. 7 and fig. 8, in the case that the electronic device is in the screen locking state, when both face recognition and fingerprint recognition are recognized, the electronic device can directly start the camera application to display the shooting interface of the camera application, so that the starting time of the camera is reduced, and the user can shoot in time.

Referring to fig. 9, a flowchart of a photographing method according to another embodiment of the present application is shown. As an example and not by way of limitation, as shown in fig. 9, the photographing method may include the steps of:

s901, when the electronic equipment is in a screen locking state, detecting a first operation of a user, wherein the first operation is used for triggering face recognition.

S902, responding to the first operation, starting face recognition, and obtaining a first recognition result.

S903, if the first recognition result indicates that the face recognition passes, detecting a second operation of the user, wherein the second operation is used for triggering fingerprint recognition.

S904, responding to the second operation, starting fingerprint identification, and obtaining a second identification result.

Steps S901 to S904 are the same as steps S701 to S704, and specific reference may be made to the descriptions of steps S701 to S704, and the description thereof will not be repeated here.

And S905, if the second recognition result indicates that the fingerprint recognition is passed, acquiring a first shooting parameter corresponding to the first fingerprint information.

The first fingerprint information is the fingerprint information currently input by the user.

As described in step S904, a preset relationship table is stored in the electronic device. Accordingly, one implementation of S905 includes: acquiring a preset relation table; searching whether the first fingerprint information exists in the preset relation table; if the first fingerprint information exists in the preset relation table, acquiring the first shooting parameters corresponding to the first fingerprint information from the preset relation table; if the first fingerprint information does not exist in the preset relation table, a preset default parameter can be determined to be a first shooting parameter corresponding to the first fingerprint information.

In one implementation manner, if the second recognition result indicates that the fingerprint recognition fails, it is indicated that the user does not set shooting parameters for the current fingerprint information, and a third interface is displayed, where the third interface is an interface of a desktop application of the electronic device.

S906, starting a camera application, and displaying a second interface, wherein the second interface is an interface of a shooting mode of the camera application, and the second interface comprises the first shooting parameters.

In the embodiment of the application, the shooting parameters corresponding to the fingerprint information input by the current user are displayed through the second interface, so that the user experience is improved.

S907, detecting a fourth operation of the second interface by the user.

S908, responding to the fourth operation, shooting according to the first shooting parameters, and obtaining a second photo.

Exemplary, referring to fig. 10, a schematic diagram of a photographing procedure according to another embodiment of the present application is provided. As shown in fig. 10 (a), a screen lock interface 61 of the electronic device is shown, and the electronic device is in a screen lock state. When the user performs a first operation (e.g., the user picks up the cell phone, presses a power key, operates on a screen (clicks, slides, etc.), pulls out a charging wire, etc.), the electronic device starts face recognition in response to the first operation, displaying a recognition interface 62 as shown in (b) of fig. 10. The identification interface 62 may include an identification of face recognition (e.g., the "face ID" shown in fig. 10 (b)) to indicate to the user that face recognition is currently being performed. An identification 601 of the fingerprint identification area may also be included in the identification interface 62 to prompt the user to enter fingerprint information. In case a second operation of the user is detected (e.g. the user's finger presses the identification 601 of the fingerprint identification area), the electronic device may perform face recognition and fingerprint identification in sequence. When the face recognition passes and the fingerprint recognition passes, the electronic device jumps to the photographing interface 63 as shown in (c) of fig. 10. The electronic equipment starts the camera application after unlocking the screen and jumps to the shooting interface of the camera application. The photographing interface 63 includes a parameter display area 603 therein, and the parameter display area 603 displays therein a first photographing parameter corresponding to fingerprint information currently input by a user. When the user performs a third operation (e.g., clicks on the photographing control 602, double-clicks on the screen or double-clicks on the back panel of the electronic device, etc.), in response to the third operation, the electronic device photographs a second picture according to the first photographing parameter (e.g., white balance "ISO" of 200, exposure time "S" of 1/100, "AF" of 35, and ZOOM of 0.5 as shown in (c) of fig. 10). As shown in fig. 10 (d) with the capture interface 64, a second photograph is displayed within the preview pane 604.

Compared with the application scene shown in the embodiment of fig. 8, in the application scene shown in the embodiment of fig. 10, the shooting parameters corresponding to the fingerprint information currently input by the user are displayed on the shooting interface, and when the user performs the shooting operation, shooting is performed according to the shooting parameters. By the method, the shooting effect is more in line with the expectations of users, the steps of parameter adjustment of the users are reduced, the shooting efficiency is improved, and timely shooting requirements are met.

As shown in fig. 9 and fig. 10, when the electronic device is in the screen locking state and both face recognition and fingerprint recognition are recognized, the electronic device may directly start the camera application, display a shooting interface of the camera application, and after the user performs a shooting operation, perform shooting according to shooting parameters corresponding to fingerprint information input by the current user. By the method, the starting time of the camera can be reduced, and timely shooting of a user is facilitated; in addition, shooting can be performed according to shooting parameters preset by a user, so that shooting effects meet user expectations while timely shooting is ensured, and user experience is improved.

Referring to fig. 11, a flowchart of a photographing method according to another embodiment of the present application is shown. As an example and not by way of limitation, as shown in fig. 11, the photographing method may include the steps of:

S1101, detecting a first operation of a user when the electronic equipment is in a screen locking state, wherein the first operation is used for triggering face recognition.

S1102, responding to the first operation, starting face recognition and obtaining a first recognition result.

And S1103, if the first recognition result indicates that the face recognition passes, detecting a second operation of the user, wherein the second operation is used for triggering fingerprint recognition.

S1104, responding to the second operation, starting fingerprint identification, and obtaining a second identification result.

S1105, if the second recognition result indicates that fingerprint recognition passes, acquiring a first shooting parameter corresponding to the first fingerprint information.

And S1106, starting a camera application, and displaying a second interface, wherein the second interface is an interface of a shooting mode of the camera application, and the second interface comprises the first shooting parameters.

Steps S1101 to S1106 are the same as steps S901 to S906, and specific reference may be made to the descriptions of steps S901 to S906, and are not repeated here.

S1107, detecting whether a preset object is contained in the view-finding frame of the second interface.

In this embodiment of the present application, the preset object may include category information of the photographing object, a sample image of the photographing object, and the like.

In some implementations, a trained detection model may be stored in the electronic device, which may be used to detect multiple types of photographic subjects, such as "people", "animals", and the like. The electronic equipment displays a plurality of types which can be identified by the detection model through the interactive interface so as to be selected by a user. After the user selects, the electronic device sets the type selected by the user as a preset object. Correspondingly, in the detection process of the execution S1107, the electronic equipment acquires an image in a camera viewfinder, and inputs the image into a trained detection model for image detection; if the detection result shows that the type corresponding to the image is the preset object, judging that the view frame of the current second interface contains the preset object.

In other implementations, the user may input a sample image of the photographed object into the electronic device, and after the electronic device acquires the sample image, the sample image is set as a preset object and stored. Correspondingly, in the detection process of the execution S1107, the electronic equipment acquires an image in a camera viewfinder, and performs matching processing on the image and a sample image; and if the matching result shows that the two images contain the same shooting object, judging that the current viewfinder of the second interface contains the preset object.

It should be noted that the foregoing is merely an example of a preset object and a detection manner thereof, in practical application, other preset objects may be set as required, or whether the viewfinder of the camera includes the preset object may be judged by adopting other detection manners, which is not specifically limited in the embodiment of the present application.

S1108, if the current view-finding frame of the second interface contains a preset object, shooting according to the first shooting parameters to obtain a third photo.

Exemplary, referring to fig. 12, a schematic diagram of a photographing procedure according to another embodiment of the present application is provided. As shown in fig. 12 (a), a screen lock interface 71 of the electronic device is shown, and the electronic device is in a screen lock state. When the user performs a first operation (e.g., the user picks up the cell phone, presses a power key, operates on a screen (clicks, slides, etc.), pulls out a charging wire, etc.), the electronic device activates face recognition in response to the first operation, displaying a recognition interface 72 as shown in (b) of fig. 12. The identification interface 72 may include an identification of face recognition (e.g., the "face ID" shown in fig. 12 (b)) to indicate that the user is currently performing face recognition. An identification 701 of the fingerprint identification area may also be included in the identification interface 72 to prompt the user to enter fingerprint information. In case that the second operation of the user is detected (e.g., the user's finger presses the identification 701 of the fingerprint recognition area), the electronic device may perform face recognition and fingerprint recognition in sequence. When the face recognition passes and the fingerprint recognition passes, the electronic device jumps to the photographing interface 73 as shown in (c) in fig. 12. The electronic equipment starts the camera application after unlocking the screen and jumps to the shooting interface of the camera application. The photographing interface 73 includes a parameter display area 702 therein, and the parameter display area 702 displays therein a first photographing parameter corresponding to fingerprint information currently input by a user. After the electronic device starts the camera application, it is detected whether the image in the viewfinder 703 of the camera contains a preset object. If the image in the viewfinder 703 of the camera includes the preset object, the electronic device photographs according to the first photographing parameter, and obtains a third photograph. As shown in (c) and (d) of fig. 12, when the image in the viewfinder 703 contains a preset object, the electronic device performs shooting according to the shooting parameters in the parameter display area 702, and the resulting third photograph is displayed in the preview frame 704.

Compared with the application scene shown in the embodiment of fig. 10, the application scene shown in the embodiment of fig. 12 can automatically capture images when a preset object appears in the viewfinder, and does not need to wait for user operation. The mode can improve shooting efficiency and meet the requirement of timely shooting.

As shown in the embodiments of fig. 7 to fig. 12, compared with the application scenario shown in the embodiment of fig. 1, the photographing method provided in the embodiment of the present application can quickly start the camera and photograph when the electronic device is in the screen locking state, skip the step of jumping to the desktop, reduce the operation steps of the user, provide the photographing efficiency, and facilitate the improvement of the user experience.

And under the condition that the second operation of the user (namely the operation for triggering fingerprint identification) is not detected or the fingerprint identification is not passed, the electronic equipment can unlock by looking at the normal unlocking flow and jump to the desktop application. In this way, the unlocking operation of the electronic device is performed normally, and the daily operation of the user is not affected.

Exemplary, referring to fig. 13, a schematic diagram of an application scenario provided in an embodiment of the present application is shown. As shown in fig. 13 (a), a screen lock interface 81 of the electronic device is shown, and the electronic device is in a screen lock state. When the user performs a first operation (e.g., the user picks up the cell phone, presses a power key, operates on a screen (clicks, slides, etc.), pulls out a charging wire, etc.), the electronic device starts face recognition in response to the first operation, displaying a recognition interface 82 as shown in (b) of fig. 13. The identification interface 82 may include an identification of face recognition (e.g., the "face ID" shown in fig. 13 (b)) to indicate that the user is currently performing face recognition. An identification 801 of the fingerprint identification area may also be included in the identification interface 82 to prompt the user to enter fingerprint information.

In this case, if the face recognition passes, but the second operation of the user is not detected, or the fingerprint recognition does not pass, the electronic device jumps to the desktop interface 83 shown in fig. 13 (c).

In another case, if the second operation of the user is detected and both face recognition and fingerprint recognition are passed, the electronic device starts the camera and jumps to the photographing interface 84 shown in fig. 13 (d).

According to the shooting method, the flexibility is high, and a user can control the electronic equipment to unlock a screen or quickly start camera shooting through user operation. Through the mode, the user experience is improved.
