For example, users can use the digital video (DV) mode of the camera application to simulate handheld video recording using a DV camera. However, when using handheld video recording, users need to support the phone with one hand and press the capture button simultaneously to take the photo, which causes inconvenience to the user.

[0005] Summary of the Invention

[0006] In view of the above, it is necessary to provide a photographing operation method, a terminal device and a storage medium to solve the technical problem of inconvenience in user photographing operation.

[0007] In the first aspect, an embodiment of the present application provides a method for photographing, which is applied to a terminal device.

The above technical solution, when it is determined that the user triggers the designated button of the camera interface, adds a new hot zone on the camera interface, and changes the functional hot zone to which the target hot zone belongs according to the second preset switching rule to update the target hot zone, thereby facilitating the user to call the function of the target button in the target hot zone.

[0013] In one embodiment of the present application, the third preset operation is a double-click operation on the fingerprint reader, and the fourth preset operation is a swipe operation on the fingerprint reader. In the above technical solution, when the user double-clicks the fingerprint reader, the terminal device can quickly change the target hotspot, and when the user swipes the fingerprint reader, the terminal device can quickly change the target button, thereby making it easier for the user to call the function of the target button of the camera application.

[0014] In one embodiment of the present application, the newly added hot zone includes at least one sub-hot zone, and at least one sub-hot zone includes a button or a progress bar.

[0015] In one embodiment of the present application, in response to a user operation received by the fingerprint reader, invoking a function of a target button to take a photo includes: if the user operation is recognized as a first preset operation, invoking the function of the target button or taking a photo based on a target parameter value. The above technical solution can invoke the function of the target button in the sub-hotspot or take a photo based on the target parameter value when it is detected that the user has applied the first preset operation to the fingerprint reader.

[0016] In one embodiment of the present application, at least one functional hot zone includes a first hot zone, a second hot zone and a third hot zone. The first hot zone includes at least one photo mode setting button, which is used to set the photo working mode. The second hot zone includes at least one focus button, which is used to set the focus mode. The third hot zone includes at least one function setting button, which is used to set the function corresponding to the function setting button.

[0017] In a second aspect, an embodiment of the present application provides a method for photographing, applied to a terminal device, the method comprising: when the terminal device is in an unlocked state, if it is determined that the terminal device is folded to a preset angle range and the terminal device is in a handheld posture, waking up the fingerprint identifier of the terminal device; identifying a user operation through the fingerprint identifier; if the user operation is a preset photographing operation, setting the photographing working mode of the camera application to photographing mode, and taking a photo in accordance with the photographing mode; if the user operation is a preset video recording operation, setting the photographing working mode of the camera application to video recording mode, and taking a photo in accordance with the video recording mode.

In this way, the user can quickly enter the camera photographing function through the preset photographing operation, or quickly enter the camera video recording function through the preset video recording operation, thereby simplifying the action process of the photographing operation and improving the efficiency of the photographing operation.

[0018] In one embodiment of the present application, the method further includes: obtaining posture information of the terminal device, and determining whether the terminal device is in a handheld posture according to the posture information. The above technical solution can determine whether the terminal device is in a handheld posture according to the posture information of the terminal device.

[0019] In one embodiment of the present application, waking up a fingerprint reader of a terminal device includes: a processor of the terminal device sending a drive signal to the fingerprint reader, causing the fingerprint reader to enter an awake state, and the fingerprint reader reporting measured user operation information to the processor while in the awake state.

[0040] In the related art, electronic devices with foldable screen functions, such as mobile phones, are adapted to camera applications for handheld video recording. For example, referring to Figure 1, a user uses the digital video (DV) mode of the camera application to perform handheld video recording, where 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 press the shooting button of the mobile phone to complete the photo shooting at the same time, which causes inconvenience to the user's operation.

[0041] 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. Referring to Figure 2, it is a schematic diagram of the structure of a 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 take images or videos. The display screen 12 is used to display the display content of the terminal device 100, for example, 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 it recognizes 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, making it convenient for the user to perform photo operations.

[0042] 3 is a flowchart of a method for taking a photo in accordance with an embodiment of the present invention. The method is applied to a terminal device, such as the terminal device 100 in FIG2 , and specifically includes the following steps.

[0043] Step S301: Determine whether the terminal device enters a camera application scenario.

[0044] The following describes the camera operation method of an embodiment of the present application using 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 mobile phone's desktop. 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 the mobile phone has entered by recording the currently running application. For example, after the user triggers the camera application icon on the mobile phone's desktop, 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 the mobile phone has entered is the camera application scene based on the recorded name of the currently running camera application.

[0045] 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, for example, it can be an instant messaging application. The following uses the instant messaging application as an example to illustrate the mobile phone entering the camera application scenario. Referring to Figure 4, the user calls the camera function by clicking the capture button in the chat interface of the instant messaging application. If the mobile phone detects the user clicking the capture 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 scenario entered by the mobile phone is the camera application scenario based on the recorded name of the currently running camera application.

[0046] 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.

[0047] Step S302 : displaying a camera interface, wherein the camera interface includes at least one function hot zone, and the at least one function hot zone includes a target hot zone, and a target button is set in the target hot zone.

[0048] In one embodiment of the present application, if it is determined that the terminal device has entered the camera application scenario, the mobile phone displays a camera interface including at least one function hot zone on the display screen 12. The function hot zone may refer to a functional area for human-computer interaction on the camera interface. One or more function setting buttons may be displayed in the function area, and different function setting buttons are used to set different functions. Referring to Figure 5, a schematic diagram of the camera interface in one embodiment of the present application is shown. The camera interface 50 includes at least one function hot zone 51 and an image preview area 52. The function 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 has touched the photo mode setting button in the first hot zone 511, the corresponding photo mode is set according to the triggered photo mode setting button; if it is detected that the user has touched the shutter button, the camera application controls the camera 11 to take a photo. For example, if it is detected that the user has triggered the night scene button, the photo mode is set to night scene mode; if it is detected that the user has touched the portrait button, the photo mode is set to portrait mode; if it is detected that the user has touched the shutter button, the camera application is controlled to call the camera 11 to take a photo.

[0049] The second hot zone 512 is a focus selection area, 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 buttons include, but are 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 area, 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.

[0050] In one embodiment of the present application, the target hot zone refers to an area where buttons or controls in the camera interface are used as operation objects. For example, referring to Figure 5, the mobile phone can receive the user's operation to change the target button in the target hot zone, such as performing a sliding operation 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.

[0051] Step S303: Detect 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, execute step S304. If it is detected that the terminal device is folded into the preset angle range, execute step S305.

[0052] In one embodiment of the present application, when a user folds the display screen of a mobile phone and takes a photo or video, 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 based on 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.

[0053] In one embodiment of the present application, the preset angle range can be set based on the angle required to bend the phone in DV mode to take photos. For example, the angle required to bend the phone in DV mode to take photos is generally close to 90°, so the preset angle range can be set within a range close to 90°, for example, setting the preset angle range to [80°, 100°].

[0054] Step S304: If it is recognized that the user has touched the shutter button on the camera interface, the function of the target button is called to take a photo.

[0055] 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 on the camera interface, the mobile phone can recognize the user's operation of touching the shutter button on the camera interface and call the function of the target button to take a photo.

[0056] Step S305: Wake up the fingerprint identifier and identify the user operation through the fingerprint identifier.

[0057] In one embodiment of the present application, when it is determined that the mobile phone is folded into a preset angle range, or when it is determined that the mobile phone is working in DV mode for recording, the fingerprint identifier is awakened. In another embodiment of the present application, when it is detected that the mobile phone is folded into 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 into 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 enter the awake state, thereby waking up the fingerprint identifier 13. 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.

[0058] In one embodiment of the present application, the fingerprint identifier 13 may be a capacitive fingerprint identifier. When the capacitive fingerprint identifier is in an awake state, it reports the measured capacitance change information to the processor 14. When the capacitive fingerprint identifier is in a dormant state, it does not measure the capacitance change information or does not upload the measured capacitance change information to the processor 14. In another embodiment of the present application, the fingerprint identifier 13 may be a temperature sensor fingerprint identifier. When the temperature sensor fingerprint identifier is in an awake state, it reports the measured temperature change information to the processor 14. When the temperature sensor fingerprint identifier is in a dormant state, it does not measure the temperature change information or does not upload the measured temperature change information to the processor 14. In other embodiments, the fingerprint identifier may also be an optical fingerprint identifier, an ultrasonic fingerprint identifier, or an electromagnetic wave fingerprint identifier. The present application does not limit the type of the fingerprint identifier 13.

[0059] 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 this field. For example, a capacitive fingerprint identifier measures the capacitance change and / or time change information when the 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.

[0060] Step S306: Based on the user operation, the function of the target button is called to take a photo.

[0061] In one embodiment of the present application, based on the user operation, calling the function of the target button to take a photo includes: if the user operation is the first preset operation, taking a photo according to the function of the target button. In the 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 single-clicking the fingerprint identifier 13. Reference Figure 6 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 has single-clicked the fingerprint identifier 13, the mobile phone calls the function of the target button to take a photo. This avoids the problem that the user can only use the shutter button to start taking a photo in the handheld video recording scenario, which causes operational inconvenience, thereby improving the convenience of the user in taking photos.

[0062] In another embodiment of the present application, taking photos according to the function of the target button based on a user operation includes: if the user operation is a second preset operation, taking continuous photos according to the function of the target button. The second preset operation can be used to initiate continuous photo taking. 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 reader 13. If the user is detected to have long-pressed the fingerprint reader 13, the mobile phone takes continuous photos according to the function of the target button. This avoids the inconvenience of the user having to select and touch the continuous shooting button to initiate continuous photo taking in handheld camera scenarios, thereby improving the convenience of the user in performing continuous photo taking operations.

[0063] 7 is a flow chart of a method for taking a photo in accordance with an embodiment of the present invention, which includes the following steps.

[0064] Step S701: Determine whether the terminal device enters a camera application scenario.

[0065] Step S702 : displaying a camera interface, wherein the camera interface includes at least one function hot zone, and the at least one function hot zone includes a target hot zone, and a target button is set in the target hot zone.

[0066] Step S703: Detect 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, execute step S704. If it is detected that the terminal device is folded into the preset angle range, execute step S705.

[0067] Step S704: If it is recognized that the user has touched the shutter button on the camera interface, the function of the target button is called to take a photo.

[0068] Step S705: Wake up the fingerprint identifier and identify the user operation through the fingerprint identifier.

[0069] For the specific implementation of steps S701-S705, please refer to the description of steps S301-S305 above, which will not be described in detail here.

[0070] Step S706: If the recognized user operation is the third preset operation, determine the updated target hot zone.

[0071] In one embodiment of the present application, the third preset operation can be pre-set based on user needs. For example, the third preset operation can be set to a double-click on the fingerprint reader 13. In this embodiment of the present application, the third preset operation can be used to update the target hot zone. Referring to FIG8 , 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 on the fingerprint reader 13, the second hot zone 512 is used as the updated target hot zone in response to the double-click on the fingerprint reader 13. After determining that the second hot zone 512 is the updated target hot zone, if the mobile phone detects that the user double-clicked the fingerprint reader 13 again, the third hot zone 513 is used as the updated target hot zone. After determining that the third hot zone 513 is the target hot zone, if the mobile phone detects that the user double-clicked the fingerprint reader 13 again, the first hot zone 511 is used as the updated target hot zone. In this way, by continuously double-clicking the fingerprint reader 13, 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. For a specific implementation method of switching the target hot zone, refer to the method flow chart shown in FIG11 .

[0072] Step S707: If the recognized user operation is the fourth preset operation, the target button in the updated target hot zone is changed.

[0073] In one embodiment of the present application, the fourth preset operation can be pre-set according to user needs. For example, the fourth preset operation can be set to the operation of sliding the fingerprint identifier 13. The fourth preset operation can be used to update the target button. Referring to Figure 9, 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. The mobile phone can recognize the user's sliding operation on the fingerprint identifier 13 and, in response to the sliding operation on the fingerprint identifier 13, switch the target button in the first hot zone 511 from the photo button to the video button in the first hot zone 511.

[0074] Step S708: If the user's operation is recognized as the first preset operation, the function of the target button is called to take a photo.

[0075] In one embodiment of the present application, the specific implementation content of step S708 can refer to step S306 and will not be repeated here.

[0076] 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 picture, so that the user starts the camera to take a picture by applying the first preset operation to the fingerprint identifier 13, which facilitates the user's operation of taking pictures in a handheld camera scene and improves operating efficiency.

[0077] In one embodiment of the present application, referring to Figure 10, when the first hot zone 511 is determined to be 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 and use the updated sub-hot zone as the target hot zone through a third preset operation (such as double-clicking the fingerprint identifier 13), and update the sub-button in the sub-hot zone or adjust the value in the progress bar through a fourth preset operation (such as sliding the fingerprint identifier 13). 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 of the fingerprint identifier 13 is recognized, and the sub-button in the sub-hot zone is updated in response to the sliding of the fingerprint identifier 13 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.

[0078] In one embodiment of the present application, the sub-hot zones of the fourth hot zone 514 include, but are not limited to, a photometric sub-hot zone and a sensitivity sub-hot zone. The photometric sub-hot zone includes at least a matrix metering button, a center-weighted metering mode button, and a spot metering mode button. The matrix metering button is used to set the metering mode to matrix metering mode, the center-weighted metering mode button is used to set the metering mode to center-weighted metering mode, and the spot metering mode button is used to set the metering mode to spot metering mode. The sensitivity sub-hot zone includes a sensitivity adjustment progress bar, which is used to adjust the sensitivity.

[0079] 11 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.

[0080] Step S1101: Determine the functional hot zone to which the target hot zone belongs.

[0081] In one embodiment of the present application, the mobile phone's camera application records a flag bit of the target hot zone, which 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 based on the flag bit of the target hot zone. For example, if the flag bit of the target hot zone recorded by the mobile phone's camera application indicates the first hot zone, 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.

[0082] In step S1102 , if the user operation on the fingerprint identifier is identified as the third preset operation, the target hot zone is changed according to the first preset switching rule based on the functional hot zone to which the target hot zone belongs, so as to update the target hot zone.

[0083] In one embodiment of the present application, the first preset switching rule may be to change the functional hot zone to which the target hot zone belongs according to a cyclic switching rule of the first hot zone 511, the second hot zone 512, and the third hot zone 513 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 first hot zone 511, if the user is identified to perform a double-click operation on the fingerprint identifier 13, the functional 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 functional hot zone to which the target hot zone belongs is changed to the second hot zone 411, if the user is identified to perform a double-click operation on the fingerprint identifier 13 again, the functional 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 functional hot zone to which the target hot zone belongs is changed to the third hot zone 513, if the user is identified to perform a double-click operation on the fingerprint identifier 13 again, the functional hot zone to which the target hot zone belongs is changed from the third hot zone 513 to the first hot zone 511.

[0084] Step S1103: Determine whether the designated button is triggered.

[0085] In one embodiment of the present application, the designated button is a button for setting the operating mode to professional mode. For example, the designated button may be a button for determining that the professional button is triggered if the user updates the camera interface through a sliding operation. 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.

[0086] Step S1104: display the fourth hot zone.

[0087] 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 reader 13, and the professional button is updated as the target button in the first hot zone 511 by sliding the fingerprint reader 13 to trigger the professional button.

[0088] Step S1105: Determine the functional hot zone to which the target hot zone belongs.

[0089] 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.

[0090] Step S1106 : If the user operation on the fingerprint identifier is identified as the third preset operation, the target hot zone is changed according to the second preset switching rule based on the functional hot zone to which the target hot zone belongs, so as to update the target hot zone.

[0091] 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 a 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 has double-clicked the fingerprint identifier 13, the functional hot zone to which the target hot zone belongs is changed from the fourth hot zone 514 to a 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 a sub-hot zone of the fourth hot zone 514, if it is recognized that the user has double-clicked the fingerprint identifier 13, the functional hot zone to which the target hot zone belongs is changed from a sub-hot zone of the fourth hot zone 514 to another sub-hot zone of the fourth hot zone 514. After all sub-hot zones of the fourth hot zone 514 are changed, if the identified user double-clicks the fingerprint reader 13, the functional hot zone to which the target hot zone belongs is changed from a 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 reader 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 reader 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 reader 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.

[0092] In one embodiment of the present application, if it is recognized that the user has not operated the camera interface for 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 commonly used 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 recognized, and the target hot zone is changed from the fourth hot zone 514 to the second hot zone 512. It is not necessary to wait until all sub-hot zones of the fourth hot zone 514 are changed before changing to the second hot zone 512, thereby improving the convenience of the user in changing the target hot zone.

[0093] 12 is a flow chart of a method for taking a photo in another embodiment of the present application, which includes the following steps.

[0094] Step S1201: When the terminal device is determined to be 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.

[0095] In one embodiment of the present application, the unlocked state refers to the state in which the screen has been exited from lock. In one embodiment of the present application, if the mobile phone is in the locked screen state, the mobile phone may receive a password or pattern input by the user. If the received password matches a preset password, or the received pattern matches a preset pattern, the terminal device is determined to have exited the state described on the screen and is determined to be unlocked. The specific implementation details of determining whether the terminal device is folded within the preset angle range can be referred to the specific implementation details of step S303 above and will not be described in detail here.

[0096] Step S1202: Detect whether the terminal device is in a hand-held posture. If it is determined that the terminal device is in a hand-held posture, execute step S1203; if it is determined that the terminal device is not in a hand-held posture, execute step S1201.

[0097] 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 based on the posture information. The posture information of the mobile phone may include but is not limited to information on position, direction and angle.

[0098] Step S1203: Wake up the fingerprint identifier and identify the user operation through the fingerprint identifier.

[0099] 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.

[0100] 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 photo mode, and the photo is taken according to the photo mode.

[0101] In one embodiment of the present application, the sixth preset operation may be a preset photo-taking operation, which may be pre-set according to user needs, such as setting the sixth preset operation to the operation of double-clicking the fingerprint reader 13. For example, after the mobile phone recognizes the user's double-clicking of the fingerprint reader 13, the mobile phone sets the camera application to photo-taking mode and takes a photo in the photo-taking mode.

[0102] In step S1205 , if the user operation is recognized as the seventh preset operation, the camera application's photographing mode is set to the video recording mode, and photographing is performed in the video recording mode.

[0103] In one embodiment of the present application, the seventh preset operation may be a preset video recording operation. 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 user's operation of long-pressing the fingerprint identifier 13, it sets the camera application to video recording mode and takes a photo in video recording mode. It should be noted that the user operations involved in the above embodiments can be adjusted according to actual applications, and this application does not impose any restrictions on this.

[0104] In the above embodiment, when it is detected that the terminal device is folded to a preset angle range and the terminal device is in a handheld posture, the camera application can be quickly accessed 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 photo mode, and the photo is taken in the photo mode. If the fingerprint identifier recognizes that the user operation is the seventh preset operation, the camera application's photo mode is set to video mode, and the photo is taken in the video mode. In this way, quickly entering the camera's photo function through the sixth preset operation, or quickly entering the camera's video function through the seventh preset operation, simplifies the photo operation process, facilitates the user's photo operation, and improves photo efficiency.

[0105] 13 is a flow chart of a volume adjustment method according to an embodiment of the present application. The method is applied to a terminal device, such as the terminal device 100 in FIG2 , and specifically includes the following steps.

[0106] Step S1301: Determine whether the terminal device enters an audio application scenario.

[0107] In one embodiment of the present application, a user triggers an application icon on the mobile phone's desktop. 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 the mobile phone is currently in by recording the currently running application. For example, after a user triggers the audio application icon on the mobile phone's desktop, the mobile phone runs the audio application in the foreground and records the name of the currently running audio application. Based on the recorded name of the currently running audio application, the mobile phone determines that the application scenario the mobile phone has entered is an audio application scenario. 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.

[0108] Step S1302: Wake up the fingerprint identifier and identify user operations through the fingerprint identifier.

[0109] In one embodiment of the present application, the specific implementation of step S1302 refers to the implementation of step S305 and will not be described again here.

[0110] Step S1303: Adjust the volume of the audio application according to the user operation.

[0111] In one embodiment of the present application, adjusting the volume of an audio application based on a 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. In this embodiment of the present application, the user operation is identified by a fingerprint identifier and the volume of the audio application is adjusted based on 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 button, thereby reducing the hardware resource overhead of the terminal device.
