[0038] In the related art, electronic devices with foldable screen functions such as mobile phones will adapt camera applications to perform handheld photography. Figure 1 , users use the digital video (DV) mode of the camera application to perform handheld video recording, wherein the DV mode refers to a mode in which the mobile phone simulates the shooting effect of a DV camera. However, when the user performs handheld video recording, the user needs to support the mobile phone with one hand and operate the shooting button of the mobile phone to complete the photo shooting, which causes inconvenience to the user's operation.

[0039] In order to solve the above problems, the present application provides a method for taking a photo. The method is applied in a terminal device. Figure 2As shown, it is a schematic diagram of the structure of the terminal device in an embodiment of the present application. The terminal device 100 can be an electronic product with a folding screen function such as a mobile phone or a tablet. The terminal device 100 includes a camera 11, a display screen 12, a fingerprint identifier 13, a processor 14 and a motion sensor 15. The processor 14 is connected to the camera 11, the display screen 12, the fingerprint identifier 13, and the motion sensor 15 respectively. The camera 11 is used to shoot images or videos. The display screen 12 is used to display the display content of the terminal device 100, for example, to display the camera interface of the camera application. The fingerprint identifier 13 is used to identify the user's fingerprint information and operation information. The motion sensor 15 is used to detect the posture information of the terminal device 100. The processor 14 is used to wake up the fingerprint identifier 13 according to the posture information of the motion sensor 15 when identifying that the application scenario of the terminal device 100 is a camera application scenario, detect the user's operation information through the fingerprint identifier 13, and call the function of the camera application's photo button to take a photo according to the user's operation information. In this way, by performing a quick operation on the fingerprint identifier 13, the camera application's photo function is completed, which is convenient for the user to perform a photo operation.

[0040] refer to Figure 3 , which is a flow chart of a method for taking a photo in one embodiment of the present application. The method is applied to a terminal device, such as Figure 2 The terminal device 100 specifically includes the following steps.

[0041] Step S301, determining whether the terminal device enters a camera application scenario.

[0042] The following introduces the camera operation method of the embodiment of the present application by taking a mobile phone as an example of a terminal device. In one embodiment of the present application, a user triggers an application icon on the desktop of a mobile phone. If the mobile phone detects that the user has triggered the application icon, it runs the application in the foreground and records the currently running application. The mobile phone can determine the application scene that the mobile phone has entered by recording the currently running application. For example, after the user triggers the icon of the camera application on the desktop of the mobile phone, the mobile phone runs the camera application in the foreground and records the name of the currently running camera application. The mobile phone determines that the application scene that the mobile phone has entered is the camera application scene based on the recorded name of the currently running camera application.

[0043] In another embodiment of the present application, the user can call the camera function through user operation in the interface of the target application of the mobile phone. If the mobile phone detects the user operation of calling the camera function, the mobile phone jumps from the target application to the camera application, runs the camera application in the foreground and records the currently running camera application. The mobile phone determines that the application scenario entered by the mobile phone is the camera application scenario by recording the name of the currently running camera application. The target application is an application with a camera function, such as an instant messaging application. The following uses an instant messaging application as an example to illustrate how the mobile phone enters the camera application scenario. Reference Figure 4 , the user clicks the shooting button in the chat interface of the instant messaging application to call the camera function. If the mobile phone detects that the user clicks the shooting button, it jumps from the instant messaging application to the camera application. The mobile phone runs the camera application in the foreground and records the name of the currently running camera application. The mobile phone determines that the application scene entered by the mobile phone is the camera application scene based on the recorded name of the currently running camera application.

[0044] If it is determined that the terminal device has entered the camera application scene, step S302 is executed; if it is determined that the terminal device has not entered the camera application scene, step S301 is continued to be executed.

[0045] Step S302, displaying a camera interface, wherein the camera interface includes at least one functional hot zone, the at least one functional hot zone includes a target hot zone, and a target button is disposed in the target hot zone.

[0046] In one embodiment of the present application, if it is determined that the terminal device enters the camera application scene, the mobile phone displays a camera interface including at least one functional hot zone on the display screen 12. The functional hot zone may refer to a functional area for human-computer interaction on the camera interface, and one or more function setting buttons may be displayed in the functional area, and different function setting buttons are used to set different functions. Figure 5 As shown, it is a schematic diagram of a camera interface in an embodiment of the present application. The camera interface 50 includes at least one functional hot zone 51 and an image preview area 52. The functional hot zone 51 includes a first hot zone 511, a second hot zone 512 and a third hot zone 513. The first hot zone 511 includes at least one photo mode setting button and a shutter button. The function of the photo mode setting button is to set the photo working mode of the camera application. The function of the shutter button is to start the camera 11 to take a photo. The photo mode setting button includes, but is not limited to, a night scene button, a portrait button, a photo button, a video button, a movie button, and a professional button. If it is detected that the user touches the photo mode setting button in the first hot zone 511, the corresponding photo working mode is set according to the triggered photo mode setting button; if it is detected that the user touches the shutter button, the camera 11 is controlled by the camera application to take a photo. For example, if it is detected that the user triggers the night scene button, the photo working mode is set to the night scene mode, if it is detected that the user touches the portrait button, the photo working mode is set to the portrait mode, and if it is detected that the user touches the shutter button, the camera application is controlled to call the camera 11 to take a photo.

[0047] The second hot zone 512 is a focus selection zone, including at least one focus button. The function of the focus button is to set the focus mode. If it is detected that the user touches the focus button, the corresponding focus mode is set according to the triggered focus button. In one embodiment of the present application, the focus button includes, but is not limited to, a 0.5x focus button, a 1x focus button, and a 2.5x focus button. For example, if it is detected that the user touches the 0.5x focus button, the focus mode is set to 0.5x. The third hot zone 513 is a function selection zone, including at least one function setting button. The function setting buttons include, but are not limited to: a visual button, an artificial intelligence (AI) camera button, a flash button, a filter button, and a setting button. If it is detected that the user touches any button in the third hot zone 513, the corresponding function is set according to the touched button. For example, if it is detected that the user touches the filter button, the filter is set.

[0048] In one embodiment of the present application, the target hot zone refers to an area where a button or control in the camera interface is used as an operation object. Figure 5 , the mobile phone can receive the user's operation to change the target button in the target hot zone, such as sliding on the display screen 12, and change the current target button in the target hot zone, and the changed target button is highlighted in the target hot zone. In one embodiment of the present application, when the camera interface is displayed, the first hot zone 511 is selected as the target hot zone by default, and the photo button in the target hot zone is selected as the target button by default. In one embodiment of the present application, the functional hot zone of the non-target hot zone includes a target button. For example, after selecting the first hot zone 511 as the target hot zone, the 1x focus button of the second hot zone 512 of the non-target hot zone is used as the target button.

[0049] Step S303, detecting whether the terminal device is folded into a preset angle range. If it is detected that the terminal device is not folded into the preset angle range, executing step S304. If it is detected that the terminal device is folded into the preset angle range, executing step S305.

[0050] In one embodiment of the present application, when the user takes a photo or video after folding the display screen of the mobile phone, the mobile phone obtains the posture information of the mobile phone detected by the motion sensor, and calculates the angle of the mobile phone after bending according to the posture information. The motion sensor may include at least one of an accelerometer sensor, a gyroscope and a magnetometer. For example, the mobile phone can use one or more sensors such as an accelerometer sensor, a gyroscope and a magnetometer to obtain the posture information of the mobile phone. Among them, the accelerometer can measure the acceleration of the mobile phone in three directions of a coordinate system (such as a three-dimensional space coordinate system or an Android coordinate system), the gyroscope can measure the angular velocity of the mobile phone in three directions, and the magnetometer can measure the magnetic field strength of the mobile phone in three directions. Through these data, the posture information of the mobile phone can be calculated. The posture information of the mobile phone may include but is not limited to information on position, direction and angle, such as the folding angle of the mobile phone.

[0051] In one embodiment of the present application, the preset angle range can be set according to the angle at which the mobile phone needs to be bent to take photos in the DV mode. For example, the angle at which the mobile phone needs to be bent to take photos in the DV mode is generally close to 90°, and the preset angle range can be set in the vicinity of 90°, for example, the preset angle range is set to [80°, 100°].

[0052] Step S304: if it is recognized that the user touches the shutter button on the camera interface, the function of the target button is called to take a photo.

[0053] In one embodiment of the present application, when the mobile phone is not folded to a preset angle range, if the user touches the shutter button of the camera interface, the mobile phone can recognize the user's operation of touching the shutter button of the camera interface and call the function of the target button to take a photo.

[0054] Step S305, waking up the fingerprint identifier and identifying the user operation through the fingerprint identifier.

[0055] In one embodiment of the present application, when it is determined that the mobile phone is folded to a preset angle range, or when it is determined that the mobile phone is working in DV mode for video recording, the fingerprint identifier is awakened. In another embodiment of the present application, when it is detected that the mobile phone is folded to a preset angle range, it can be determined that the mobile phone is working in DV mode. In one embodiment of the present application, when it is determined that the mobile phone is folded to a preset angle range or the mobile phone is working in DV mode, the processor 14 of the mobile phone sends a drive signal to the fingerprint identifier 13 to make the fingerprint identifier 13 exit the sleep state and go to the awake state, thereby waking up the fingerprint identifier 13. Among them, in the awake state, the fingerprint identifier 13 reports the measured user operation information to the processor 14; in the sleep state, the fingerprint identifier 13 does not measure the user operation information, or does not report the measured user operation information to the processor 14. In other embodiments, when the mobile phone determines that it has entered the camera application scenario, it can directly wake up the fingerprint identifier and identify the user operation through the fingerprint identifier.

[0056] In one embodiment of the present application, the fingerprint identifier 13 may be a capacitive fingerprint identifier, which reports the measured capacitance change information to the processor 14 when in the awake state; and does not measure the capacitance change information or upload the measured capacitance change information to the processor 14 when in the sleep state. In another embodiment of the present application, the fingerprint identifier 13 may be a temperature sensor fingerprint identifier, which reports the measured temperature change information to the processor 14 when in the awake state, and does not measure the temperature change information or upload the measured temperature change information to the processor 14 when in the sleep state. In other embodiments, the fingerprint identifier may also be an optical fingerprint identifier, an ultrasonic fingerprint identifier, or an electromagnetic wave fingerprint identifier, and the present application does not limit the type of the fingerprint identifier 13.

[0057] In one embodiment of the present application, identifying a user operation through a fingerprint identifier includes: identifying a user operation through a fingerprint identifier, and the user operation may include but is not limited to: a single-click operation, a double-click operation, a sliding operation, and a long-press operation. Identifying a user's single-click operation, double-click operation, sliding operation, and long-press operation through a fingerprint identifier is a prior art means in the art. For example, a capacitive fingerprint identifier is used to measure the capacitance change and / or time change information when a user operates the capacitive fingerprint identifier, and the user's single-click operation, double-click operation, sliding operation, or long-press operation can be identified. This embodiment of the present application will not be described in detail.

[0058] Step S306: according to the user operation, the function of the target button is called to take a photo.

[0059] In one embodiment of the present application, according to the user operation, calling the function of the target button to take a photo includes: if the user operation is a first preset operation, taking a photo according to the function of the target button. In an embodiment of the present application, the first preset operation can be used to start the camera to take a photo. The first preset operation can be pre-set according to user needs, such as setting the first preset operation to the operation of clicking the fingerprint identifier 13. Reference Figure 6 As shown, it is a schematic diagram of clicking the fingerprint identifier to take a photo in one embodiment of the present application. In one embodiment of the present application, the fingerprint identifier 13 is installed on the side of the mobile phone, which is convenient for the user to touch when using the mobile phone for handheld video recording. If it is recognized that the user clicks the fingerprint identifier 13, the mobile phone calls the function of the target button to take a photo, thus avoiding the problem that the user can only use the shutter button to start taking a photo in the scene of handheld video recording, which causes inconvenience in operation, and improves the convenience of the user's photo operation.

[0060] In another embodiment of the present application, taking photos according to the function of the target button according to the user operation includes: if the user operation is a second preset operation, taking photos continuously according to the function of the target button. The second preset operation can be used to start continuous photography. The second preset operation can be pre-set according to user needs, such as setting the second preset operation to an operation of long pressing the fingerprint identifier 13. If it is recognized that the user long presses the fingerprint identifier 13, the mobile phone takes photos continuously according to the function of the target button, thereby avoiding the problem of the user needing to select the continuous shooting button and touch it to start continuous photography in the scene of handheld video recording, which causes inconvenience in operation, and improves the convenience of the user in performing continuous photography operations.

[0061] refer to Figure 7 FIG. 1 is a flow chart of a method for taking photos in an embodiment of the present application. The method comprises the following steps.

[0062] Step S701, determining whether the terminal device enters a camera application scenario.

[0063] Step S702, displaying a camera interface, wherein the camera interface includes at least one functional hot zone, the at least one functional hot zone includes a target hot zone, and a target button is disposed in the target hot zone.

[0064] Step S703, detecting whether the terminal device is folded into a preset angle range. If it is detected that the terminal device is not folded into the preset angle range, executing step S704. If it is detected that the terminal device is folded into the preset angle range, executing step S705.

[0065] Step S704: If it is recognized that the user touches the shutter button on the camera interface, the function of the target button is called to take a photo.

[0066] Step S705, waking up the fingerprint identifier and identifying the user operation through the fingerprint identifier.

[0067] For the specific implementation contents of steps S701-S705, please refer to the description contents of the above steps S301-S305, which will not be described in detail here.

[0068] Step S706: If the recognized user operation is the third preset operation, determine the updated target hot zone.

[0069] In one embodiment of the present application, the third preset operation can be pre-set according to user needs, such as setting the third preset operation to the operation of double-clicking the fingerprint identifier 13. In the embodiment of the present application, the third preset operation can be used to update the target hot zone. Figure 8 As shown, when the first hot zone 511 is determined as the target hot zone, if the mobile phone recognizes that the user operation is a double-click operation of the fingerprint identifier 13, then in response to the double-click operation of the fingerprint identifier 13, the second hot zone 512 is used as the updated target hot zone. After determining the second hot zone 512 as the updated target hot zone, if the mobile phone detects that the user double-clicks the fingerprint identifier 13 again, the third hot zone 513 is used as the updated target hot zone. After determining the third hot zone 513 as the target hot zone, if the mobile phone detects that the user double-clicks the fingerprint identifier 13 again, the first hot zone 511 is used as the updated target hot zone. In this way, the user can cyclically switch between the first hot zone 511, the second hot zone 512, and the third hot zone 513 to update the target hot zone by continuously double-clicking the fingerprint identifier 13. The specific implementation method of switching the target hot zone is shown in FIG. Fig.11 The method flow chart is shown.

[0070] Step S707: if the recognized user operation is the fourth preset operation, the target button in the updated target hot zone is changed.

[0071] In one embodiment of the present application, the fourth preset operation can be pre-set according to user needs, such as setting the fourth preset operation to the operation of sliding the fingerprint identifier 13, and the fourth preset operation can be used to update the target button. Fig. 9 As shown, after selecting the first hot zone 511 as the target hot zone, the current default target button is the photo button. At this time, the user slides the fingerprint identifier 13, and the mobile phone can recognize the user's sliding operation on the fingerprint identifier 13, and respond to the sliding operation on the fingerprint identifier 13, and switch the target button in the first hot zone 511 from the photo button to the video recording button in the first hot zone 511.

[0072] Step S708: If the user's operation is identified as the first preset operation, the function of the target button is called to take a photo.

[0073] In one embodiment of the present application, the specific implementation content of step S708 can refer to the steps of step S306, and will not be repeated here.

[0074] In one embodiment of the present application, if the user's operation on the fingerprint identifier 13 is identified as the third preset operation, the mobile phone updates the target hot zone, so that the user updates the target hot zone of the camera interface by applying the third preset operation to the fingerprint identifier 13; if the user's operation on the fingerprint identifier 13 is identified as the fourth preset operation, the mobile phone updates the target button in the target hot zone of the fingerprint identifier 13, so that the user updates the target button in the target hot zone by applying the fourth preset operation to the fingerprint identifier 13; if the user's operation on the fingerprint identifier 13 is identified as the first preset operation, the function of the target button is called to take a photo, so that the user starts the camera to take a photo by applying the first preset operation to the fingerprint identifier 13, which facilitates the user's operation of taking photos in a handheld camera scene and improves operating efficiency.

[0075] In one embodiment of the present application, reference Fig.10 , when determining that the first hot zone 511 is the target hot zone, if it is recognized that the user updates the target button by sliding the fingerprint identifier 13, and updates the professional button to the target button, the mobile phone displays the fourth hot zone 514 on the camera interface, and uses the fourth hot zone 514 as the target hot zone. The fourth hot zone 514 is the function setting area of ​​the professional button. The fourth hot zone 514 includes at least one sub-hot zone, and each sub-hot zone includes a sub-button or a progress bar. The user can update the sub-hot zone in the fourth hot zone 514 through a third preset operation (such as double-clicking the fingerprint identifier 13) and use the updated sub-hot zone as the target hot zone, and update the sub-button in the sub-hot zone through a fourth preset operation (such as sliding the fingerprint identifier 13), or adjust the value in the progress bar. Specifically, when determining that the fourth hot zone 514 is the target hot zone, if the mobile phone recognizes the user's double-clicking of the fingerprint identifier 13, the sub-hot zone in the fourth hot zone 514 is updated in response to the double-clicking of the fingerprint identifier 13, and the updated sub-hot zone is used as the target hot zone; the user's sliding fingerprint identifier 13 is recognized, and in response to the sliding fingerprint identifier 13, the sub-button in the sub-hot zone is updated and the updated sub-button is used as the target button, or the value in the progress bar is adjusted and the adjusted value is used as the target parameter value; if the mobile phone recognizes the user's clicking of the fingerprint identifier 13, the function of the target button is called or a photo is taken according to the target parameter value.

[0076] In one embodiment of the present application, the sub-hot zones of the fourth hot zone 514 include but are not limited to the photometric sub-hot zone and the sensitivity sub-hot zone. The photometric sub-hot zone includes at least a matrix photometric button, a center-weighted photometric mode button, and a spot photometric mode button. The matrix photometric button is used to set the photometric mode to the matrix photometric mode, the center-weighted photometric mode button is used to set the photometric mode to the center-weighted photometric mode, and the spot photometric mode button is used to set the photometric mode to the spot photometric mode. The sensitivity sub-hot zone includes a sensitivity adjustment progress bar, and the sensitivity adjustment progress bar is used to adjust the sensitivity.

[0077] refer to Fig.11 FIG. 1 is a flow chart of a method for switching a target hot zone in an embodiment of the present application. The method includes the following steps.

[0078] Step S1101, determining the functional hot zone to which the target hot zone belongs.

[0079] In one embodiment of the present application, the camera application of the mobile phone records the flag bit of the target hot zone, and the flag bit is used to indicate the identity information of the functional hot zone; the functional hot zone to which the target hot zone belongs is determined according to the flag bit of the target hot zone. For example, if the flag bit of the target hot zone recorded by the camera application of the mobile phone indicates the first hot zone, then the functional hot zone to which the target hot zone belongs is determined to be the first hot zone. In one embodiment of the present application, the flag bit can be a string of numbers and letters.

[0080] Step S1102: if the user operation on the fingerprint identifier is identified as the third preset operation, based on the functional hot zone to which the target hot zone belongs, the target hot zone is changed according to the first preset switching rule to update the target hot zone.

[0081] In one embodiment of the present application, the first preset switching rule may be to change the function hot zone to which the target hot zone belongs according to the cyclic switching rule of the first hot zone 511, the second hot zone 512, and the third hot zone 513, so as to update the target hot zone. For example, when it is determined that the function hot zone to which the target hot zone belongs is the first hot zone 511, if the user is identified to double-click the fingerprint identifier 13, the function hot zone to which the target hot zone belongs is changed from the first hot zone 511 to the second hot zone 512. After the function hot zone to which the target hot zone belongs is changed to the second hot zone 411, if the user is identified to double-click the fingerprint identifier 13 again, the function hot zone to which the target hot zone belongs is changed from the second hot zone 512 to the third hot zone 513. After the function hot zone to which the target hot zone belongs is changed to the third hot zone 513, if the user is identified to double-click the fingerprint identifier 13 again, the function hot zone to which the target hot zone belongs is changed from the third hot zone 513 to the first hot zone 511.

[0082] Step S1103, determining whether the designated button is triggered.

[0083] In one embodiment of the present application, the designated button is a button for setting the working mode to the professional mode. For example, the designated button may be a button for determining that the professional button is triggered if the professional button for updating the camera interface through a sliding operation by the user is identified as the target button. In one embodiment of the present application, if the professional button is determined to be triggered, step S1104 is executed; if the professional button is determined not to be triggered, step S1101 is executed.

[0084] Step S1104, displaying the fourth hot zone.

[0085] In one embodiment of the present application, if the triggering of the professional button is detected, the mobile phone adds and displays a fourth hot zone 514 on the camera interface. In one embodiment of the present application, the professional button can be triggered by touching the professional button on the camera interface. In another embodiment of the present application, the first hot zone 511 is selected as the target hot zone by double-clicking the fingerprint identifier 13, and the professional button is updated as the target button in the first hot zone 511 by sliding the fingerprint identifier 13 to trigger the professional button.

[0086] Step S1105, determining the functional hot zone to which the target hot zone belongs.

[0087] In one embodiment of the present application, the specific implementation content of step S1105 refers to the content of step S1102 and will not be repeated here.

[0088] Step S1106: if the user operation on the fingerprint identifier is identified as the third preset operation, based on the functional hot zone to which the target hot zone belongs, the target hot zone is changed according to the second preset switching rule to update the target hot zone.

[0089] In one embodiment of the present application, the second preset switching rule may be to change the functional hot zone to which the target hot zone belongs according to the cyclic switching rule of the fourth hot zone 514, the sub-hot zone of the fourth hot zone, the second hot zone 512, the third hot zone 513, and the first hot zone 511, so as to update the target hot zone. For example, when it is determined that the functional hot zone to which the target hot zone belongs is the fourth hot zone 514, if it is recognized that the user double-clicks the fingerprint identifier 13, the functional hot zone to which the target hot zone belongs is changed from the fourth hot zone 514 to the sub-hot zone of the fourth hot zone 514. When it is determined that the functional hot zone to which the target hot zone belongs is the sub-hot zone of the fourth hot zone 514, if it is recognized that the user double-clicks the fingerprint identifier 13, the functional hot zone to which the target hot zone belongs is changed from the sub-hot zone of the fourth hot zone 514 to another sub-hot zone of the fourth hot zone 514. After all the sub-hot zones of the fourth hot zone 514 are changed, if the identified user double-clicks the fingerprint identifier 13, the functional hot zone to which the target hot zone belongs is changed from the sub-hot zone of the fourth hot zone 514 to the second hot zone 512. After the functional hot zone to which the target hot zone belongs is changed to the second hot zone 411, if the identified user double-clicks the fingerprint identifier 13 again, the target hot zone is switched from the second hot zone 512 to the third hot zone 513. After the functional hot zone to which the target hot zone belongs is changed to the third hot zone 513, if the identified user double-clicks the fingerprint identifier 13 again, the target hot zone is switched from the third hot zone 513 to the first hot zone 511. After the functional hot zone to which the target hot zone belongs is changed to the first hot zone 511, if the identified user double-clicks the fingerprint identifier 13 again, the functional hot zone to which the target hot zone belongs is switched from the first hot zone 511 to the fourth hot zone 514.

[0090] In one embodiment of the present application, if it is recognized that the user has no operation on the camera interface within a preset time, the display of the fourth hot zone 514 is exited, and the first hot zone 511 is used as the target hot zone. By exiting the display of the fourth hot zone 514 on the camera interface, it is convenient for the user to set the common functions of the camera application. In another embodiment of the present application, the fifth preset operation of the user on the fingerprint identifier 13 is identified, and the target hot zone is changed from the fourth hot zone 514 to the second hot zone 512. It is not necessary to change to the second hot zone 512 after all the sub-hot zones of the fourth hot zone 514 are changed. This improves the convenience of the user in changing the target hot zone.

[0091] refer to Fig.12 , which is a flow chart of a method for taking photos in another embodiment of the present application. The method comprises the following steps.

[0092] Step S1201, when it is determined that the terminal device is in the unlocked state, determine whether the terminal device is folded into a preset angle range. If the terminal device is folded into the preset angle range, execute step S1202. If the terminal device is not folded into the preset angle range, execute step S1201.

[0093] In one embodiment of the present application, the unlocked state refers to the state of exiting the screen lock. In one embodiment of the present application, if the mobile phone is in the screen lock state, the mobile phone can receive a password or pattern input by the user. If the received password is consistent with the preset password, or the received pattern is consistent with the preset pattern, it is determined that the terminal device exits the state described by the screen, and the terminal device is determined to be in the unlocked state. The specific implementation content of determining whether the terminal device is folded to the preset angle range can refer to the specific implementation content of the above step S303, which will not be described in detail here.

[0094] Step S1202, detecting whether the posture of the terminal device is a hand-held posture. If it is determined that the posture of the terminal device is a hand-held posture, executing step S1203, if it is determined that the posture of the terminal device is not a hand-held posture, executing step S1201.

[0095] In one embodiment of the present application, the mobile phone obtains the posture information of the mobile phone detected by the motion sensor, and determines whether the mobile phone is in a handheld posture according to the posture information. The posture information of the mobile phone may include but is not limited to information on position, direction and angle.

[0096] Step S1203, waking up the fingerprint identifier and identifying the user operation through the fingerprint identifier.

[0097] In one embodiment of the present application, the specific implementation content of waking up the fingerprint identifier and identifying the user operation through the fingerprint identifier can refer to the implementation content of step S305, which will not be repeated here.

[0098] Step S1204: if the user operation is recognized as the sixth preset operation, the camera operation mode of the camera application is set to the camera mode, and the camera is taken according to the camera mode.

[0099] In one embodiment of the present application, the sixth preset operation may be a preset photo-taking operation, and the sixth preset operation may be pre-set according to user needs, such as setting the sixth preset operation to the operation of double-clicking the fingerprint identifier 13. For example, after the mobile phone recognizes the operation of the user double-clicking the fingerprint identifier 13, the camera application is set to the photo-taking mode, and the photo is taken according to the photo-taking mode.

[0100] Step S1205: If the user operation is recognized as the seventh preset operation, the camera application's photographing working mode is set to the video recording mode, and photographing is performed in accordance with the video recording mode.

[0101] In one embodiment of the present application, the seventh preset operation may be a preset video recording operation, and the seventh preset operation may be pre-set according to user needs, such as setting the seventh preset operation to an operation of long pressing the fingerprint identifier 13. For example, after the mobile phone recognizes the operation of the user long pressing the fingerprint identifier 13, the camera application is set to the video recording mode, and the photo is taken in accordance with the video recording mode. It should be noted that the user operations involved in the above embodiments may be adjusted according to actual applications, and the present application does not limit this.

[0102] In the above embodiment, when it is detected that the terminal device is folded to a preset angle range and the posture of the terminal device is a handheld posture, the camera application can be quickly entered and the fingerprint identifier can be awakened. If the fingerprint identifier recognizes that the user operation is the sixth preset operation, the camera application's photo mode is set to the photo mode, and the photo is taken in the photo mode. If the user operation is recognized as the seventh preset operation, the camera application's photo mode is set to the video mode, and the photo is taken in the video mode. In this way, the camera photo function is quickly entered through the sixth preset operation, or the camera video function is quickly entered through the seventh preset operation, which simplifies the action process of the photo operation, facilitates the user to perform the photo operation, and improves the efficiency of photo taking.

[0104] Step S1301, determining whether the terminal device enters an audio application scenario.

[0105] In one embodiment of the present application, a user triggers an application icon on the desktop of a mobile phone. If the mobile phone detects that the user has triggered the application icon, it runs the application in the foreground and records the currently running application. The mobile phone can identify the application scenario that the mobile phone is currently in by recording the currently running application. For example, after a user triggers the icon of an audio application on the desktop of a mobile phone, the mobile phone runs the audio application in the foreground and records the name of the currently running audio application. The mobile phone determines that the application scenario that the mobile phone has entered is an audio application scenario based on the recorded name of the currently running audio application. In one embodiment of the present application, an audio application refers to an application that can play sound, for example, an audio application can be a music application, a video application, etc.

[0106] Step S1302, waking up the fingerprint identifier and identifying the user operation through the fingerprint identifier.

[0107] In an embodiment of the present application, the specific implementation content of step S1302 refers to the implementation content of step S305, and will not be described again here.

[0108] Step S1303: adjusting the volume of the audio application according to the user operation.

[0109] In one embodiment of the present application, adjusting the volume of the audio application according to the user operation includes: if the user operation is identified as a first sliding operation, turning up the volume of the audio application; if the user operation is identified as a second sliding operation, turning down the volume of the audio application, wherein the direction of the first sliding operation is opposite to the direction of the second sliding operation. The embodiment of the present application identifies the user operation through a fingerprint identifier and adjusts the volume of the audio application according to the user operation. The volume can be adjusted by operating the fingerprint identifier, thereby replacing the existing terminal device solution of adjusting the volume by pressing the volume key, thereby reducing the hardware resource overhead of the terminal device.
