Description

Technical Field

[0001] The present application relates to the technical field of mobile terminals, and in particular to a mobile terminal and an interaction method of the mobile terminal. Background Art

[0002] When using a mobile terminal such as a mobile phone or tablet computer, if you want to adjust a certain parameter in the mobile terminal, the user generally needs to free up one hand and perform a touch operation on the touch screen. For example, when a user holds a mobile phone to take a photo, when you need to adjust a certain parameter in the captured image, such as adjusting the focal length, you need to free up one hand to click or slide on the display screen. In this way, it is easy to cause the mobile terminal to be held unsteadily, causing the image to shake. And when the user holds the mobile terminal, one hand holds it and the other hand operates on the display screen, which affects the user's image preview on the one hand; on the other hand, due to the unstable grip, the adjustment may not be precise enough, thereby affecting the user's interactive experience with the mobile terminal. Summary of the invention

[0003] The present application provides a mobile terminal and an interaction method of the mobile terminal, which realizes interaction with the mobile terminal by setting an adjustment ring on the mobile terminal and adjusting certain parameters in the mobile terminal by rotating the adjustment ring, is easy to operate, and improves the user experience.

[0004] In the first aspect, the present application provides a mobile terminal, including a terminal body and an adjustment ring, a camera module is provided on one side of the terminal body, the camera module protrudes from a back cover of the terminal body, the adjustment ring is sleeved on the camera module and the adjustment ring protrudes from the back cover, the camera module is fixed relative to the terminal body, and the adjustment ring can rotate along the camera module.

[0005] On this basis, by setting the adjustment ring to be sleeved on the camera module and the adjustment ring protruding from the back cover, the part of the adjustment ring protruding from the back cover is convenient for the user to control, and it is sleeved on the camera module without occupying other positions of the mobile terminal, and is integrated with the camera module, making the appearance of the mobile terminal more beautiful. By setting the adjustment ring to rotate along the camera module, the parameters of some functions of the mobile terminal can be adjusted by rotating the adjustment ring, which is easy to operate and can be operated by the user with one hand.

[0006] In a possible design of the first aspect, a connecting plate is provided on the adjusting ring, the connecting plate is located inside the terminal body, a signal transmitter is provided on the connecting plate, a sensor is provided inside the terminal body, and the sensor detects the position of the signal transmitter to obtain the rotation information of the adjusting ring.

[0007] On this basis, by setting a signal transmitter on the connecting board and a sensor inside the terminal body, the sensor can detect the signal strength of the signal transmitter to determine the position of the signal transmitter, thereby detecting the rotation of the adjustment ring and converting the physical rotation of the adjustment ring into a corresponding electrical signal.

[0008] In a possible design of the first aspect, the adjustment ring is in the shape of a ring, and the adjustment ring can rotate 360° around the camera module. The connecting plate is in the shape of a ring, and the connecting plate is sleeved on the circumference of the adjustment ring. The inner diameter of the connecting plate is equal to the outer diameter of the adjustment ring. On this basis, by setting the adjustment ring to rotate 360° around the camera module, the rotation flexibility of the adjustment ring is improved. The larger the rotation angle of the adjustment ring, the more accurate the adjustment of the parameter to be adjusted can be. The connecting plate is set to a ring shape as a specific setting method, and can also be set to other shapes.

[0009] In a possible design of the first aspect, the adjustment ring is provided with anti-skid patterns, and the anti-skid patterns are located outside the terminal body. By providing the anti-skid patterns on the adjustment ring, when the user rotates the adjustment ring, the friction between the hand and the adjustment ring is increased to prevent slipping, which may lead to inaccurate adjustment.

[0010] In a second aspect, the present application provides an interactive method of a mobile terminal, the method being applied to a mobile terminal, the mobile terminal comprising an adjustment ring, the method comprising:

[0011] Start the application in the mobile terminal, and the preset screen after the application is started is displayed on the display screen of the mobile terminal. When the user rotates the adjustment ring, the rotation information of the adjustment ring is obtained. The adjustment instruction corresponding to the rotation information is determined; the preset screen is adjusted according to the adjustment instruction, and the adjusted screen is displayed on the display screen. In this embodiment, after the user starts the mobile program, the parameters to be adjusted in the preset screen are mainly adjusted by rotating the adjustment ring. The user can hold the mobile terminal with one hand and use one of the fingers to turn the adjustment ring to achieve the corresponding adjustment, which is very convenient to operate. The user can determine the specific adjustment amount according to the preset screen, and the adjustment can be stopped when the adjusted screen displayed on the display screen reaches the user's preset target.

[0012] In a possible design of the second aspect, if the user rotates the adjustment ring once in one direction, the rotation information of the adjustment ring includes: direction information, the direction information includes whether the adjustment ring rotates clockwise or counterclockwise. And angle information, the angle information is the angle of rotation of the adjustment ring in one direction. When the user rotates the adjustment ring, different adjustment directions and adjustment amounts can be achieved through different rotation directions and rotation angles.

[0013] In a possible design of the second aspect, determining the adjustment instruction corresponding to the rotation information includes: determining the adjustment direction according to the direction information, the adjustment direction including: increasing the parameter to be adjusted and decreasing the parameter to be adjusted. According to the correspondence between the angle information and the parameter to be adjusted, determining the adjustment amount corresponding to the angle information, and obtaining the adjustment instruction including the adjustment direction and the adjustment amount. Since the adjustment ring has two rotation directions, the adjustment direction (increasing or decreasing) of the parameter to be adjusted can be determined according to its rotation direction, and the rotation angle of the adjustment ring is generally larger, which can be used to correspond to the specific adjustment amount, so as to facilitate precise adjustment.

[0014] In a possible design of the second aspect, the method includes: if the adjustment ring rotates clockwise, determining the adjustment direction is to increase the parameter to be adjusted; if the adjustment ring rotates counterclockwise, determining the adjustment direction is to increase the parameter to be adjusted. Alternatively, if the adjustment ring rotates counterclockwise, determining the adjustment direction is to decrease the parameter to be adjusted; if the adjustment ring rotates clockwise, determining the adjustment direction is to increase the parameter to be adjusted.

[0015] In a possible design of the second aspect, the application is a camera application, and the method includes: starting the camera application in the mobile terminal, and displaying a shooting preview screen on the display screen of the mobile terminal. When the user rotates the adjustment ring, the rotation information of the adjustment ring is obtained. The adjustment instruction corresponding to the rotation information is determined; the shooting preview screen is adjusted according to the adjustment instruction, and the image collected after the adjustment is displayed on the display screen. This design method shows a method of interaction with a mobile terminal in a specific application scenario.

[0016] In a possible design of the second aspect, after the camera application in the mobile terminal is started and the shooting preview screen is displayed on the display screen of the mobile terminal, the method also includes: switching the required functional mode in the shooting preview screen, and the functional mode includes a first function and a second function. If the selected functional mode is the first function, the adjustment instruction is used to adjust the parameters corresponding to the first function; if the selected functional mode is the second function, the adjustment instruction is used to adjust the parameters corresponding to the second function. When adjusting the parameters, since rotating the adjustment ring once can generally only adjust one parameter to be adjusted, when there are multiple parameters to be adjusted, it is necessary to first determine the parameter to be adjusted, and then adjust the size of the parameter to be adjusted by rotating the adjustment ring. Of course, after adjusting one of the parameters to be adjusted, the next parameter to be adjusted can also be selected, and the adjustment ring can be rotated to adjust the size of the next parameter to be adjusted.

[0017] In a possible design of the second aspect, if the user rotates the adjustment ring twice in a row in one direction, the adjustment instruction corresponding to the rotation of the adjustment ring is: switch between the first function and the second function. This design defines a new adjustment instruction, that is, adjusting the size of the parameter to be adjusted generally requires rotating the adjustment ring once. However, the new adjustment instruction can also be implemented by other operations of rotating the adjustment ring, such as rotating the adjustment ring twice in a row in one direction.

[0018] In a possible design manner of the second aspect, the first function is zoom adjustment, and determining the zoom adjustment instruction corresponding to the rotation information includes: determining the zoom adjustment direction according to the direction information, and the zoom adjustment direction includes: increasing the focal length and decreasing the focal length. According to the correspondence between the angle information and the focal length adjustment amount, determining the focal length adjustment amount corresponding to the angle information, and obtaining the zoom adjustment instruction including the zoom adjustment direction and the focal length adjustment amount.

[0019] The second function is exposure adjustment, and determining the exposure adjustment instruction corresponding to the rotation information includes: determining the exposure adjustment direction according to the direction information, and the exposure adjustment direction includes: increasing the exposure amount and decreasing the exposure amount. According to the correspondence between the angle information and the exposure adjustment amount, determining the exposure adjustment amount corresponding to the angle information, and obtaining the exposure adjustment instruction including the exposure adjustment direction and the exposure adjustment amount.

[0020] In a possible design manner of the second aspect, the method includes: if the selected function mode is the first function, determining the zoom adjustment direction includes:

[0021] If the adjustment ring is rotated clockwise, it is determined that the zoom adjustment direction is to increase the focal length; if the adjustment ring is rotated counterclockwise, it is determined that the focus adjustment direction is to decrease the focal length. Alternatively, if the adjustment ring is rotated counterclockwise, it is determined that the zoom adjustment direction is to increase the focal length; if the adjustment ring is rotated clockwise, it is determined that the focus adjustment direction is to decrease the focal length.

[0022] If the selected function mode is the second function, determining the exposure adjustment direction includes:

[0023] If the adjustment ring is rotated clockwise, it is determined that the exposure adjustment direction is to increase the exposure; if the adjustment ring is rotated counterclockwise, it is determined that the focus adjustment direction is to decrease the exposure. Alternatively, if the adjustment ring is rotated counterclockwise, it is determined that the exposure adjustment direction is to increase the exposure; if the adjustment ring is rotated clockwise, it is determined that the focus adjustment direction is to decrease the exposure.

[0063] In order to solve the above problems, the embodiments of the present application provide a mobile terminal and an interactive method of the mobile terminal. The back cover of the mobile terminal is provided with an adjustment ring. When holding the mobile terminal, the user can use the finger to wave the adjustment ring to adjust the required parameters through the adjustment ring, thereby improving the user experience of the mobile terminal. The interactive method of the mobile terminal introduces a specific method of using the adjustment ring to adjust the parameters of certain applications in the mobile terminal, making the interaction between the user and the electronic device more convenient and improving the user experience.

That is, the adjustment ring 70 is rotatably connected to the terminal body 10.

[0100] refer to Figure 5 , Figure 5 The following is a schematic diagram of the structure of a camera module 20 in a mobile terminal provided in an embodiment of the present application. The camera module 20 may include a camera 22 decorative piece 21 and a camera 22.

A through hole is provided on the back cover 13, one end of the camera 22 decorative piece 21 is located in the terminal body 10, and the other end passes through the through hole on the back cover 13 and protrudes out of the back cover 13 of the terminal body 10. This part can be referred to Figure 2 . Figure 5 Also shown is an adjustment ring 70 installed on the outside of the camera module 20 , and the camera module 20 can be set inside the adjustment ring 70 .

[0101] The connection diagram between the adjustment ring 70 and the camera module 20 can be referred to Figure 6 , Figure 6 A partial structural diagram of a mobile terminal provided in an embodiment of the present application. Figure 6 As shown, the adjusting ring 70 is sleeved on the decorative piece 21 of the camera 22 of the camera module 20, wherein the camera module 20 is fixedly connected in the terminal body 10, and the adjusting ring 70 is rotatably connected to the camera module 20, that is, the adjusting ring 70 can rotate relative to the terminal body 10. For example, the decorative piece 21 of the camera 22 can be fixedly connected to the middle frame 12, the camera 22 can be fixedly connected to the main board 30, and the main board 30 is fixedly connected to the middle frame 12. One end of the adjusting ring 70 can be rotatably connected to the main board 30, and the other end of the adjusting ring 70 passes through the through hole of the back cover 13 and protrudes from the back cover 13, and the end of the adjusting ring 70 protruding from the back cover 13 is lower than the end of the camera module 20 protruding from the back cover 13, or the two are kept flush.

[0102] refer to Figure 7 and Figure 8 , Figure 7 This is a diagram showing the coordination between the adjustment ring 70 and the main board 30 in a mobile terminal provided in an embodiment of the present application. Figure 8 This is a cross-sectional view of an adjustment ring 70 in a mobile terminal provided in an embodiment of the present application. The cross-sectional view direction can refer to Figure 7 In the AA direction, it should be noted that Figure 8 Not Figure 7 Cross-sectional view along AA direction, Figure 7 The back cover 13 is not shown.

[0103] like Figure 7 , Figure 8 As shown, the camera module 20 is located in the adjustment ring 70, the adjustment ring 70 is rotationally connected to the main board 30, and the adjustment ring 70 is also rotationally connected relative to the camera module 20. A connecting plate 71 is provided on the adjustment ring 70, and the connecting plate 71 is located in the terminal body 10, that is, the connecting plate 71 is located on the side of the back cover 13 close to the middle frame 12. In order to determine the rotation direction and rotation amplitude of the adjustment ring 70, a signal transmitter 711 is also provided on the adjustment ring 70, and a sensor 80 is provided on the main board 30. Among them, the signal transmitter 711 is provided on the connecting plate 71 of the adjustment ring 70, and the signal transmitter 711 can rotate with the rotation of the adjustment ring 70. The sensor 80 can be provided in the projection area of ​​the connecting plate 71 on the main board 30, and this is provided to reduce the distance between the sensor 80 and the signal transmitter 711, so that the sensor 80 can more accurately detect the signal emitted by the signal transmitter 711.

[0104] When the user turns the adjusting ring 70 by hand, the connecting plate 71 on the adjusting ring 70 will rotate together with the adjusting ring 70, thereby driving the signal transmitter 711 disposed on the connecting plate 71 to rotate, and the sensor 80 disposed on the main board 30 detects the signal emitted by the signal transmitter 711 to determine the rotation direction and rotation angle of the signal transmitter 711. Since the signal transmitter 711 and the adjusting ring 70 rotate synchronously, the rotation direction and rotation angle of the adjusting ring 70 can be obtained by detecting the signal of the signal transmitter 711.

[0105] It should be noted that the signal transmitter 711 in the embodiment of the present application can be a magnetic object, for example, the signal transmitter 711 can be a permanent magnet. The sensor 80 can be a Hall sensor 80. The Hall sensor 80 is a transducer that can convert a changing magnetic field into a change in output voltage. Since the sensor 80 is fixed on the main board 30, when the magnet rotates with the adjustment ring 70, the rotation direction and rotation angle of the adjustment ring 70 can be determined by detecting the change in the magnetic field.

[0106] In the embodiment of the present application, the mobile terminal mainly includes an instruction input acquisition module, an instruction parsing and compiling module, an instruction receiving and executing module, and an instruction feedback display module.

[0107] The workflow of inputting instructions to the mobile terminal according to the user's preset goals and adjusting the mobile terminal so that the mobile terminal can achieve the user's preset goals can be referred to Fig. 9 . Fig. 9 The following is a schematic diagram of the working principle of a mobile terminal provided in an embodiment of the present application. Fig. 9 As shown, the user inputs the corresponding instructions to the instruction input acquisition module of the mobile terminal according to the preset target, the instruction parsing and compiling module parses the input instructions and sends them to the instruction receiving and executing module. After the instruction receiving and executing module executes the corresponding input instructions, the result after execution is presented in the instruction feedback display module. The user judges the result displayed by the instruction feedback display module. If the result does not reach the user's preset target, the user can repeat the aforementioned steps and re-enter the corresponding instructions according to the preset target until the result reaches the user's preset target. If the result reaches the user's preset target, the user can perform other operations according to the result. The other operations here can be the user performing the next operation according to the result, or it can be to keep the current result and not perform any operation. For example, the user's preset target is to adjust the shooting preview screen when taking pictures. When the adjustment result of the shooting preview screen reaches the user's preset target, the user can press the shutter button to take pictures. In this example, other operations refer to the operation of taking pictures.

[0108] Fig.10The following is a schematic diagram of the working principle of a command input acquisition module in a mobile terminal provided in an embodiment of the present application. The command input acquisition module is used to receive commands input by a user to the mobile terminal. In the embodiment of the present application, the command input acquisition module mainly refers to the adjustment loop. Fig.10 As shown, the user rotates the adjustment ring with his finger, and the adjustment ring collects information such as the rotation direction and rotation angle input by the user. The sensor converts the information such as the rotation direction and rotation angle into an electrical signal, thereby realizing the input of the corresponding adjustment command to the mobile terminal. In addition, the command input acquisition module can also be a display screen or a sound collector. For example, the user can input commands through voice, or input commands to the mobile terminal by clicking on the display screen or sliding on the display screen.

[0109] Fig.11 A schematic diagram of the working principle of an instruction parsing and compiling module in a mobile terminal provided in an embodiment of the present application. The instruction parsing and compiling module mainly refers to a processor in the mobile terminal, which is used to process the instructions input by the user collected by the instruction input acquisition module to convert them into corresponding electrical signals. In the embodiment of the present application, the instructions collected by the instruction input acquisition module refer to the initial signals such as the rotation direction and rotation angle input by the user through the adjustment ring. Therefore, the instruction parsing and compiling module mainly converts the initial signals such as the rotation direction and rotation angle of the adjustment ring into electrical signals for execution by the instruction receiving and executing module.

[0110] The principle may be that the conversion relationship between the initial signals such as the rotation direction and the rotation angle and the electrical signals to be executed by the instruction receiving and executing module is preset in the memory. Fig.11 As shown, the working principle of the instruction parsing and compiling module is: the input end of the processor receives the initial signal transmitted from the sensor, and then the processor reads the conversion relationship set in the memory, and converts the initial signal into an electrical signal for execution by the instruction receiving and executing module according to the conversion relationship, and the processor outputs the electrical signal to the instruction execution module through the output end.

[0111] It should be noted that the electrical signal executed by the instruction receiving execution module referred to in this application refers to a signal that controls a certain execution module in the mobile terminal to execute a certain command. For example, the execution module is a camera (camera module) in the mobile terminal, and the command to be executed is to adjust the position of the camera module to achieve focus. In this scenario, the electrical signal executed by the instruction receiving execution module refers to a signal used to control the movement of the camera module. If the command to be executed is to adjust the exposure of the camera. In this scenario, the electrical signal executed by the instruction receiving execution module refers to a signal that adjusts the exposure parameters of the camera module.

[0112] Fig.12A schematic diagram of the working principle of an instruction receiving and executing module in a mobile terminal provided in an embodiment of the present application. The instruction receiving and executing module is used to receive an electrical signal sent by an instruction parsing and compiling module, and execute corresponding instructions according to the electrical signal to realize the function corresponding to the user input instruction. Among them, the module includes a camera, a display screen, and other applications in the mobile terminal.

[0113] like Fig.12 As shown, the working principle of the instruction receiving and executing module is: the instruction receiving and executing module receives the electrical signal output by the processor, the executing module performs the corresponding action according to the electrical signal, and the executing module reaches the target position.

[0114] Fig.13 A schematic diagram of the working principle of a command feedback display module in a mobile terminal provided in an embodiment of the present application. The command feedback display module mainly refers to the display screen or speaker of the mobile terminal, which is used to display a screen corresponding to the user input command, or play a voice corresponding to the user input command. For example, if the command receiving and executing module is a camera, the command feedback display module mainly refers to the display screen of the mobile terminal, and the preview shooting screen of the camera is displayed on the display screen.

[0115] like Fig.13 As shown, the working principle of the instruction feedback display module is as follows: the final screen after the execution of the instruction is displayed on the preset screen, and the final screen is used to determine whether the user's preset target is reached. If the user's preset target is not reached, a new adjustment instruction is input until the final screen after adjustment reaches the user's preset target. If the user's preset target has been reached, it is determined whether the user has other needs. If there are other needs, a new adjustment instruction is input until the final screen after adjustment meets the user's needs. If there are no other needs, the preset target adjustment is completed. The final screen after the adjustment is completed is displayed on the instruction feedback display module.

[0116] The following uses an example of controlling the photographing parameters of a camera in a mobile terminal through an adjustment ring to introduce the application scenario of the adjustment ring in the embodiment of the present application.

[0117] Reference diagram of the working principle of the adjustment ring Fig.14 , taking the example of a user controlling the camera module of a mobile phone through an adjustment ring to explain the operation. Fig.14 A working principle diagram of a mobile terminal using an adjustment ring for adjustment provided in an embodiment of the present application, Fig.14 The principle of interaction with the mobile terminal through the adjustment ring is shown in FIG. Fig.14As shown, the mobile terminal is a mobile phone. When the user holds the mobile phone, if he wants to interact with the mobile phone through the adjustment ring, he can use his fingers to turn the adjustment ring on the back of the mobile phone. The adjustment ring serves as a communication medium between the mobile phone and the user, and can collect instructions input by the user. Specifically, the user's input instructions can be identified according to the rotation direction and rotation angle of the user's adjustment ring. For example, the rotation direction of the adjustment ring can include clockwise (S) and counterclockwise (N), and the rotation angle of the adjustment ring is θ, and the range of θ is 0-360°. It should be noted that the input instructions collected by the adjustment ring in the present application are specifically detected by the sensor introduced in the above embodiment.

[0118] After the adjustment ring collects the user's input command, it transmits the corresponding signal to the processor, and the processor converts the received signal corresponding to the user's input command into an electrical signal, and then sends the converted electrical signal to the camera module. The processor is connected to the memory, and the memory stores the conversion relationship between the physical signal and the electrical signal. The processor can call the conversion relationship and then convert the received physical signal into a corresponding electrical signal according to the conversion relationship.

[0119] After the camera module receives the electrical signal sent by the processor, it performs the corresponding operation according to the electrical signal to complete the user's input command. After the camera module executes the corresponding input command, the picture taken by the camera module is displayed on the display screen as a preview picture. The user can decide whether to adjust other parameters or directly shoot according to the preview picture on the display screen. If other parameters need to be adjusted, the corresponding instructions can be entered on the display screen and other parameters can be adjusted through the adjustment ring. The working principle of the adjustment ring is the same as described above.

[0120] Regarding the principle of converting the physical signal corresponding to the user input command into an electrical signal, the embodiment of the present application is explained by taking the adjustment of the focus parameter of the camera through the adjustment ring as an example.

[0121] refer to Fig.15 , Fig.15 Schematic diagram of the position change of an adjustment ring before and after adjustment in a mobile terminal provided by an embodiment of the present application. Fig.15 As shown in , before the adjustment ring in the mobile terminal is turned by the user, the signal transmitter on the adjustment ring is at point a. After the user turns the adjustment ring, the signal transmitter on the adjustment ring is at point b. The sensor on the mainboard is at point a`. Before the adjustment ring is turned, point a is directly opposite to point a`. After the adjustment ring is adjusted, the signal transmitter on the adjustment ring rotates from point a to point b. The sensor generates two pieces of information related to the rotation of the adjustment ring by detecting the signal change of the signal sensor:

[0122] (1) Direction information: S (clockwise), N (counterclockwise). Direction information S indicates that the adjustment ring rotates in the clockwise direction, and direction information N indicates that the adjustment ring rotates in the counterclockwise direction.

[0123] (2) Angle information: θ. The angle information θ indicates the angle at which the adjustment ring rotates in a certain direction. 0≤θ≤360°.

[0124] When adjusting the focus of a camera, the main thing is to control the position of the camera assembly to achieve focus. Fig.16 , Fig.16 The present invention provides a schematic diagram of the position of a camera assembly in a mobile terminal. The camera assembly has two extreme positions when it moves in the mobile terminal, one of which is called the bottom position and the other is called the top position. Fig.16 As shown, the distance between the bottommost position and the topmost position of the camera assembly is h. By adjusting the position of the camera module in the mobile terminal, the focus of the camera can be adjusted.

[0125] The conversion relationship between the rotation of the adjustment ring and the focus of the camera module is defined below.

[0126] For example, the rotation direction is first defined. For example, the direction signal S of the adjustment ring (the adjustment ring rotates clockwise) is defined as the camera module moving from the bottom position to the top position; the direction signal N of the adjustment ring (the adjustment ring rotates counterclockwise) is defined as the camera module moving from the top position to the bottom position.

[0127] Then the rotation angle is associated with the moving distance of the camera module, and the ratio of the moving distance of the camera module to the rotation angle of the adjustment ring is called the conversion coefficient K, where:

[0128]

[0129] When the user rotates the adjustment ring, the sensor transmits the physical signal of the adjustment ring rotation corresponding to the user input instruction to the processor. The processor converts the physical signal into an electrical signal that can be recognized by the camera module according to the conversion relationship defined above, and sends the electrical signal to the camera module, so that the camera module can execute the user's input instruction.

[0130] It should be noted that the embodiment of the present application only takes the conversion relationship between the rotation of the adjustment ring and the focus of the camera module as an example to illustrate the conversion relationship between the rotation information of the adjustment ring and the adjustment parameters. The definition of the conversion relationship between the rotation information of the adjustment ring and other parameters to be adjusted can refer to the above principles.

[0131] The following is a detailed description of an interactive method for a mobile terminal provided in this embodiment.

[0132] When a user wants to interact with a mobile terminal, the user can click on the application on the display screen of the mobile terminal to start the application in the mobile terminal, and the preset screen after the application is started will be displayed on the display screen of the mobile terminal. At this time, the processor in the mobile terminal will detect whether there is a signal input on the adjustment ring of the mobile terminal, that is, detect whether the adjustment ring is rotated. When the user wants to adjust the parameters in the preset screen, the adjustment ring can be turned to adjust the parameters in the preset screen corresponding to the application. When the user turns the adjustment ring, the sensor in the mobile terminal can obtain the rotation information of the adjustment ring and send the rotation information to the processor in the mobile terminal. The processor generates a corresponding adjustment instruction based on the rotation information and sends it to the execution module of the corresponding application. The execution module in the corresponding application adjusts the screen according to the adjustment instruction and displays the adjusted screen on the display screen.

[0133] For example, the application is a camera. When the user clicks the camera icon on the display screen, the mobile terminal enters the camera application and displays a shooting preview interface on the display screen of the mobile terminal. The image captured by the camera is displayed on the shooting preview interface. When the user needs to adjust the shooting parameters of the shooting preview screen, the mobile phone can be placed on the adjustment ring and rotated. After the adjustment ring rotates, the sensor detects the adjustment ring to generate corresponding rotation information, and sends the rotation information to the processor. The processor processes the rotation information and generates corresponding adjustment instructions, and sends the adjustment instructions to the camera module. Then, the camera module adjusts the corresponding shooting parameters when the camera takes pictures according to the adjustment instructions, and returns the image captured after the parameter adjustment to the processor. The processor displays the image captured after the adjustment in the shooting preview screen of the display screen through the display screen. In this program, the shooting preview screen is the preset screen.

[0134] For example, when the application is a video playback software, after the user clicks the icon of the video playback software and selects the corresponding video to play, the video playback screen of the video will be displayed on the display screen. When the user needs to adjust the display parameters of the video playback screen, the user can turn the adjustment ring, and the sensor in the mobile terminal can obtain the rotation information of the adjustment ring and send the rotation information to the processor in the mobile terminal. The processor generates a corresponding adjustment instruction based on the preset correspondence between the rotating ring and the display parameters of the video playback screen. The corresponding display parameters can be adjusted by turning the adjustment ring. In this application, the video playback screen is the preset screen. It should be noted that the specific screen display content in the preset screen may be different, which is specifically determined by the specific playback video, but the functional layout in the preset screen is the same.

[0135] For example, the preset setting between the adjustment ring and the video playback software is used to adjust the display brightness of the video playback screen in the video playback software. Among them, the preset correspondence between the rotation ring and the display brightness of the video playback screen is: rotating the adjustment ring clockwise is used to increase the display brightness of the video playback screen, and the clockwise rotation angle of the adjustment ring corresponds to the increase value of the display brightness; rotating the adjustment ring counterclockwise is used to reduce the display brightness of the video playback screen, and the counterclockwise rotation angle of the adjustment ring corresponds to the decrease value of the display brightness. When the user needs to adjust the display brightness of the video playback screen, the user can rotate the adjustment ring to generate a corresponding brightness adjustment instruction, and the mobile terminal adjusts the brightness in the video playback screen according to the brightness adjustment instruction.

[0136] For another example, the preset between the adjustment ring and the video playback software is used to adjust the display angle of the video playback screen in the video playback software (i.e., to rotate the video playback screen). Among them, the preset correspondence between the rotation ring and the display angle of the video playback screen is: rotating the adjustment ring clockwise to rotate the video playback screen clockwise, and the clockwise rotation angle of the adjustment ring corresponds to the clockwise rotation angle of the video playback screen; rotating the adjustment ring counterclockwise to rotate the video playback screen counterclockwise, and the counterclockwise rotation angle of the adjustment ring corresponds to the counterclockwise rotation angle of the video playback screen. When the user needs to rotate the video playback screen, the user can rotate the adjustment ring to generate a corresponding screen rotation adjustment instruction, and the mobile terminal rotates the video playback screen according to the screen rotation adjustment instruction.

[0137] For another example, the preset between the adjustment ring and the video playback software is used to adjust the display size of the video playback screen in the video playback software (i.e., to zoom in and out the video playback screen). Among them, the preset correspondence between the rotation ring and the display size of the video playback screen is: rotating the adjustment ring clockwise to increase the display size of the video playback screen, and the clockwise rotation angle of the adjustment ring corresponds to the magnification ratio of the video playback screen; rotating the adjustment ring counterclockwise to reduce the display size of the video playback screen, and the counterclockwise rotation angle of the adjustment ring corresponds to the reduction ratio of the video playback screen. When the user needs to zoom in and out the video playback screen, the user can rotate the adjustment ring to generate a corresponding screen zoom adjustment instruction, and the mobile terminal zooms in and out the video playback screen according to the screen zoom adjustment instruction.

[0138] Of course, the adjustment ring can also adjust the above three parameters in the video playback software at the same time. For example, the video playback screen in the video playback software is respectively provided with three adjustment options A, B, and C. Among them, adjustment option A is used to adjust the display brightness of the video playback screen, adjustment option B is used to adjust the display angle of the video playback screen, and adjustment option C is used to adjust the display size of the video playback screen. After starting the above video playback software in the mobile terminal, the display screen of the mobile terminal displays the corresponding video playback screen. When the display brightness of the video playback screen needs to be adjusted, you can click the adjustment option A in the video playback screen, and then turn the adjustment ring to adjust the display brightness of the video playback screen. When the display angle of the video playback screen needs to be adjusted, you can click the adjustment option B in the video playback screen, and then turn the adjustment ring to adjust the display brightness of the video playback screen. When the display size of the video playback screen needs to be adjusted, you can click the adjustment option C in the video playback screen, and then turn the adjustment ring to adjust the display brightness of the video playback screen.

[0139] When the user rotates the adjustment ring, different rotation modes can be used, such as clockwise rotation, counterclockwise rotation, clockwise rotation twice continuously, counterclockwise rotation twice continuously, etc. Different adjustment instructions are generated, and these adjustment instructions are defined, thereby increasing the interactivity of the mobile terminal. It should be noted that clockwise and counterclockwise in the embodiments of the present application both refer to the rotation direction of the adjustment ring when the display screen of the mobile terminal faces the user's face.

[0140] When the adjustment ring is rotated twice in a row in one direction, a corresponding instruction can be generated for switching different functional modes. Among them, it can be defined that rotating the adjustment ring twice in a clockwise direction is switching to the next functional mode; rotating the adjustment ring twice in a counterclockwise direction is switching to the previous functional mode. Or, rotating the adjustment ring twice in a clockwise direction is switching to the previous functional mode; rotating the adjustment ring twice in a counterclockwise direction is switching to the next functional mode. It should be noted that rotating twice in a row in one direction means that the adjustment ring rotates twice in a preset time t in one direction, wherein the preset time t is a shorter time, for example, time t≤1s, which can be 1s, 0.5s, or 0.2s, etc. That is, when the adjustment ring rotates twice in a direction in a shorter time, it can be considered that the adjustment ring rotates twice in a row in one direction.

[0141] For example, an application includes 4 different function modes, which are: currently in the first function state, when the adjustment ring is rotated twice in the clockwise direction, it switches to the second function; when the adjustment ring is rotated twice in the clockwise direction again, it switches to the third function; when the adjustment ring is rotated twice in the clockwise direction again, it switches to the fourth function; when the adjustment ring is rotated twice in the clockwise direction again, it switches to the first function.

[0142] It is currently in the first function state. When the adjustment ring is turned counterclockwise twice in succession, it switches to the fourth function; when the adjustment ring is turned counterclockwise twice in succession again, it switches to the third function; when the adjustment ring is turned counterclockwise twice in succession again, it switches to the second function; when the adjustment ring is turned counterclockwise twice in succession again, it switches to the first function.

[0143] Among them, the first function, the second function, the third function and the fourth function may refer to the focus, zoom, exposure adjustment, aperture adjustment and other functions in the above-mentioned "Camera" application. The first function, the second function, the third function and the fourth function may also refer to the display brightness, display angle, display size and other functions in the above-mentioned video playback software. For example, the first function is display brightness, the second function is display angle, and the third function is display size. If there are no other functions that need to be adjusted, only the first function, the second function and the third function are set on the display interface of the application. If there are other functions that need to be adjusted, the corresponding setting is the fourth function.

[0144] When the adjustment ring rotates once in one direction, a corresponding instruction can be generated to adjust a specific parameter of a function. Among them, the adjustment ring can be defined as rotating clockwise to increase or decrease a certain parameter, and correspondingly, the adjustment ring can be defined as rotating counterclockwise to decrease or increase the parameter. The rotation information of the adjustment ring rotating in one direction includes direction information and angle information. The direction information includes clockwise and counterclockwise directions; the angle information is the angle of the adjustment ring rotating in one direction. The direction information and angle information can be associated with specific parameter adjustments. For example, the direction information of the adjustment ring rotation is associated with increasing and decreasing the parameter, and the angle information of the adjustment ring rotation is associated with the specific value of the parameter adjustment.

[0145] For example, if the first function is to adjust the focus of the preview image in the camera, the instruction generated by rotating the adjustment ring once can be defined as adjusting the focus in the camera. Among them, it can be defined that the focus adjustment direction is to enlarge the focus or reduce the focus according to the rotation direction of the adjustment ring, and the specific focus adjustment amount is adjusted according to the rotation angle of the adjustment ring. If the adjustment ring rotates clockwise, the focus adjustment direction is determined to reduce the focus; if the adjustment ring rotates counterclockwise, the focus adjustment direction is determined to enlarge the focus. Alternatively, if the adjustment ring rotates counterclockwise, the focus adjustment direction is determined to reduce the focus; if the adjustment ring rotates clockwise, the focus adjustment direction is determined to enlarge the focus.

[0146] For example, the second function is to adjust the focus of the preview image in the camera, and the instruction generated by rotating the adjustment ring once can be defined as adjusting the focus amount in the camera. Among them, it can be defined that the focus adjustment direction is to increase the focus amount or to reduce the focus amount according to the rotation direction of the adjustment ring, and the specific focus adjustment amount is adjusted according to the rotation angle of the adjustment ring. If the adjustment ring rotates clockwise, the focus adjustment direction is determined to increase the focus amount; if the adjustment ring rotates counterclockwise, the focus adjustment direction is determined to reduce the focus amount. Or, if the adjustment ring rotates counterclockwise, the focus adjustment direction is determined to increase the focus amount; if the adjustment ring rotates clockwise, the focus adjustment direction is determined to reduce the focus amount. Increasing the focus amount here can refer to adjusting the camera module or the lens assembly in the camera module to move along the first direction, and correspondingly, reducing the focus amount can refer to adjusting the camera module or the lens assembly in the camera module to move along the second direction, and the first direction and the second direction are opposite directions. The focus amount can refer to the distance moved by the camera module or the lens assembly in the camera module.

[0147] For example, the third function is to adjust the exposure of the preview image in the camera, then the instruction generated by rotating the adjustment ring once can be defined as adjusting the exposure in the camera. Among them, it can be defined that the exposure adjustment direction is to increase or decrease the exposure according to the rotation direction of the adjustment ring, and the specific exposure adjustment amount is adjusted according to the rotation angle of the adjustment ring. If the adjustment ring rotates clockwise, the exposure adjustment direction is determined to increase the exposure; if the adjustment ring rotates counterclockwise, the exposure adjustment direction is determined to decrease the exposure. Alternatively, if the adjustment ring rotates counterclockwise, the exposure adjustment direction is determined to increase the exposure; if the adjustment ring rotates clockwise, the exposure adjustment direction is determined to decrease the exposure.

[0148] For example, the fourth function is to adjust the aperture size in the camera, and the instruction generated by rotating the adjustment ring once can be defined as adjusting the aperture size in the camera. Among them, it can be defined that the adjustment direction of the aperture size is determined to be increasing the aperture or decreasing the aperture according to the rotation direction of the adjustment ring, and the specific aperture adjustment amount is adjusted according to the rotation angle of the adjustment ring. If the adjustment ring rotates clockwise, the aperture adjustment direction is determined to increase the aperture; if the adjustment ring rotates counterclockwise, the aperture adjustment direction is determined to decrease the aperture. Alternatively, if the adjustment ring rotates counterclockwise, the aperture adjustment direction is determined to increase the aperture; if the adjustment ring rotates clockwise, the aperture adjustment direction is determined to decrease the aperture.

[0149] After a certain application of the mobile terminal is started, when the rotation mode of the adjustment ring is determined, the processor can access the correspondence between the rotation mode and the parameter to be adjusted pre-stored in the memory, and determine the adjustment direction and adjustment amount of the parameter to be adjusted using the determined rotation mode according to the correspondence. Then the processor generates a corresponding adjustment instruction and sends the adjustment instruction to the corresponding application, the application makes an adjustment according to the adjustment instruction, and displays the adjusted picture on the display screen of the mobile terminal.

[0150] For example, after starting the video playback software of the mobile terminal, the display screen of the mobile terminal displays the video playback screen, and at this time, the adjustment ring is rotated. If the adjustment ring is rotated twice in a row in one direction, the rotation form can correspond to the display brightness, display angle and display size in the switching video playback software, and the corresponding relationship is pre-stored in the memory. If the adjustment ring is rotated in one direction, the rotation form can correspond to the specific values ​​of adjusting the display brightness, display angle and display size, and the corresponding relationship is pre-stored in the memory.

[0151] Or, for example, after starting the camera of the mobile terminal, the display screen of the mobile terminal displays a shooting preview screen, and at this time, the adjustment ring is rotated. If the adjustment ring is rotated twice in a row in one direction, the rotation form can correspond to switching the focus, zoom, exposure adjustment and aperture adjustment functions in the camera, and the corresponding relationship is pre-stored in the memory. If the adjustment ring is rotated in one direction, the rotation form can correspond to the specific value of adjusting the focus, zoom, exposure adjustment, and aperture adjustment, and the corresponding relationship is pre-stored in the memory.

[0152] An embodiment of the present application provides a mobile terminal, which includes an adjustment ring. When the mobile terminal enters a corresponding application and displays a preset screen on a display screen of the mobile terminal, an adjustment instruction generated by a user rotating the adjustment ring is received, corresponding parameters are adjusted according to the adjustment instruction, and an image captured after the adjustment is displayed on the display screen. It can be seen that when the user uses the mobile terminal, the user only needs to free up one finger to adjust the corresponding parameters, thereby solving the problem that when the user uses the mobile terminal, the mobile terminal shakes and is inconvenient to use because the user needs to hold the mobile terminal with one hand and adjust parameters on the display screen with the other hand, making the interaction between the user and the mobile terminal more convenient and improving the user experience.

[0153] The embodiment of the present application provides an interactive method of a mobile terminal, which is mainly a method for interacting with a mobile terminal through an adjustment ring on the mobile terminal. Fig.17 , Fig.17 A schematic diagram of an interaction method of a mobile terminal provided in an embodiment of the present application.

[0154] like Fig.17 As shown, the method includes:

[0155] Step 101: Start an application in a mobile terminal, and a preset screen after the application is started is displayed on the display screen of the mobile terminal.

[0156] When the user holds the mobile terminal, the user can open the corresponding application according to the needs. For example, when the user wants to take a photo, he can click the icon corresponding to the camera on the display screen of the mobile terminal. When the camera application is started, a shooting preview screen will be displayed on the display screen. The shooting preview screen is the preset screen corresponding to the camera after it is started. For example, when the user wants to play a video, he can click the icon corresponding to the video playback software on the display screen of the mobile terminal. When the video playback software is started, the corresponding video playback screen will be displayed on the display screen. The video playback screen is the preset screen corresponding to the video playback software after it is started.

[0157] Step 102: When the user rotates the adjustment ring, the mobile terminal obtains the rotation information of the adjustment ring.

[0158] When the user starts the application he wants to use on the mobile terminal, and the corresponding preset screen has been loaded on the display screen, if the user wants to adjust the function mode or parameter, the user can turn the adjustment ring on the mobile terminal with his fingers to switch the function mode or adjust a specific parameter. When the user turns the adjustment ring, the sensor set in the mobile terminal can detect the rotation of the adjustment ring and obtain the rotation information of the adjustment ring, which includes direction information and angle information, as well as rotation time and number of rotations, and convert the physical signal formed by the rotation of the adjustment ring into an electrical signal.

[0159] Step 103: Determine an adjustment instruction corresponding to the rotation information.

[0160] After the sensor in the mobile terminal obtains the rotation information of the adjustment ring, the obtained rotation information can be sent to the processor. The processor accesses the correspondence between the rotation information and the adjustment instruction pre-stored in the memory, and determines the specific adjustment instruction based on the determined rotation information according to the correspondence, and sends the determined adjustment instruction to the execution module of the corresponding application.

[0161] Step 104: adjust the preset picture according to the adjustment instruction, and display the adjusted picture on the display screen.

[0162] After receiving the adjustment instruction sent by the processor, the execution module of the application adjusts the parameters in the preset screen corresponding to the application according to the specific content of the adjustment instruction to meet the user's predetermined adjustment target. After the execution module of the application completes the adjustment of the preset screen according to the adjustment instruction, the adjusted screen is displayed on the display screen.

[0163] It should be noted that when the user adjusts the preset screen, the user's predetermined adjustment target may include multiple parameters that need to be adjusted, so multiple adjustments may be required. After each adjustment is completed, the adjusted screen will be displayed on the display screen. The user can judge whether the currently displayed adjusted screen reaches the user's predetermined adjustment target based on the screen displayed on the display screen. If the adjusted screen has reached the user's predetermined adjustment target, the current adjusted screen can be maintained to perform subsequent corresponding operations (for example, maintaining the current display parameters for video playback, or taking pictures under the current parameters, etc.). If the adjusted screen does not reach the user's predetermined adjustment target, the corresponding parameters can be adjusted according to steps 102-104 until the user's predetermined adjustment target is reached. It should be noted that when the user's predetermined target includes adjusting multiple parameters, when switching the functions that need to be adjusted and adjusting the size of the parameters in each specific function, it can be achieved by rotating the adjustment ring in different ways according to the above steps 102-104. For example, it is defined that rotating the adjustment ring twice in a row is switched to the next function mode, and rotating the adjustment ring once is defined as adjusting the size of the parameter. When the user wants to take a photo, he needs to adjust the four parameters of focus, zoom, exposure and aperture size. The user can switch between the above functions by turning the adjustment ring twice in succession. After the switch is completed, turn the adjustment ring once to adjust the specific parameter size of the switched function. Repeat these two operations to adjust the parameters of all the above functions. After each adjustment is completed, the adjusted picture can be displayed on the display.

[0164] In order to enable those skilled in the art to more clearly understand the technical solution provided by the embodiment of the present invention, the following is a detailed description of an interactive method of a mobile terminal provided by the embodiment of the present invention through a specific embodiment. In this embodiment, the interactive method when a user uses a camera application of a mobile terminal to take a photo or record a video is taken as an example, and the corresponding steps are described in detail.

[0165] refer to Fig.18 , Fig.18 Schematic diagram of another interactive method of a mobile terminal provided in an embodiment of the present application. Fig.18 As shown, the method includes:

[0166] Step 201: Start a camera application in a mobile terminal, and display a shooting preview screen after the camera application is started on the display screen of the mobile terminal.

[0167] refer to Fig.19 and Fig. 20 , Fig.19 This is a main interface diagram of a mobile terminal provided in an embodiment of the present application. Fig. 20This is a preview screen of a mobile terminal provided in an embodiment of the present application. Fig.19 As shown, the mobile terminal is a mobile phone, and the mobile phone can display a main interface 201. The main interface 201 may include an icon 202 of a camera application. The mobile phone can receive an operation of a user clicking on the icon 202. In response to the operation, the mobile phone can open the camera application and display a shooting preview screen 203 of the camera application. The shooting preview screen 203 is as shown in FIG. Fig. 20 As shown. It can be understood that the camera application is an image capture application on electronic devices such as smartphones and tablets. It can be a system application or a third-party application. This application does not limit the name of the application. In other words, the user can click on the camera application icon 202 to open the camera application shooting preview screen 203. Not limited to this, the user can also call the camera application in other applications to open the shooting preview screen 203. For example, the user clicks the shooting control in a social application to open the shooting preview screen 203. The social application can support users to share the pictures or videos they have taken with others.

[0168] like Fig. 20 As shown, in the shooting preview screen 203 , an adjustment ring icon 204 is provided, and the mobile phone can receive an operation of a user clicking the adjustment ring icon 204 . In response to the operation, the mobile phone can display a function switching bar on the shooting preview screen 203 .

[0169] refer to Fig.21 , Fig.21 This is a function switching bar screen image in a shooting preview screen of a mobile terminal provided by an embodiment of the present application. Fig.21 As shown, when the user clicks the adjustment ring icon 204 in the shooting preview screen 203, a function switching bar is displayed on the shooting preview screen 203, wherein the function switching bar includes functions such as zoom, exposure, aperture, focus, mode switching and customization. The user can click on one of the specific functions to adjust the specific parameters of the function. In addition, the user can also set the default adjustment instructions generated by the rotation method of the adjustment ring. For example, the default setting is that rotating the adjustment ring twice in a clockwise direction continuously switches to the next function mode; rotating the adjustment ring twice in a counterclockwise direction continuously switches to the previous function mode.

[0170] by Fig.21Take the function switching bar shown in the figure as an example. If the current function state is in the zoom adjustment function, turn the adjustment ring twice clockwise to switch to the exposure adjustment function; turn the adjustment ring twice counterclockwise to switch to the custom function. If the current function state is in the aperture adjustment function, turn the adjustment ring twice clockwise to switch to the focus adjustment function; turn the adjustment ring twice counterclockwise to switch to the exposure adjustment function. If the current function state is in the mode switching function, turn the adjustment ring twice clockwise to switch to the custom function; turn the adjustment ring twice counterclockwise to switch to the focus adjustment function.

[0171] In addition, the user can also customize some instructions generated by rotating the adjustment ring, for example, the two rotation instructions of rotating the adjustment ring twice in a clockwise direction and rotating the adjustment ring twice in a counterclockwise direction can be customized. Specifically, the user can click the custom function in the function switching bar. Fig.21 Switch to Fig. 22 , Fig. 22 This is a custom operation screen diagram in a shooting preview screen of a mobile terminal provided in an embodiment of the present application. Fig. 22 As shown, after clicking the "Customize" option, a custom operation screen is displayed on the shooting preview screen 203, and the custom operation screen may include two rotation instructions of the adjustment ring, namely: two consecutive rotations in the clockwise direction and two consecutive rotations in the counterclockwise direction. Clicking one of the rotation instructions can customize the function represented by the instruction.

[0172] For example, click Fig. 22 The shooting preview screen 203 shows the option of "rotate clockwise twice continuously". Fig.23 The screen shown. Fig.23 This is one of the custom screen images in the shooting preview screen of a mobile terminal provided in an embodiment of the present application. Fig.23 As shown, the "rotate clockwise twice continuously" instruction can be bound to a corresponding function, wherein the functions that can be bound include: zoom, aperture, focus and exposure. Of course, the embodiment of the present application only specifically exemplifies the above functions, and does not limit the "rotate clockwise twice continuously" instruction to only be bound to Fig.23 For example, click Fig.23The “zoom” in the shooting preview screen 203 shown indicates that the “zoom” function is bound to the instruction of “rotate the adjustment ring twice in a clockwise direction”. When the mobile terminal opens the camera application, the user rotates the adjustment ring twice in a clockwise direction, and the function to be adjusted is switched to “zoom”. The user can adjust the “zoom” parameter size by rotating the adjustment ring again.

[0173] For example, click Fig. 22 The shooting preview screen 203 shows the option of "rotate counterclockwise twice continuously". Fig.24 The screen shown. Fig.24 This is a second custom screen image in a shooting preview screen of a mobile terminal provided in an embodiment of the present application. Fig.24 As shown, the "counterclockwise rotation twice" instruction can be bound to a corresponding function, wherein the functions that can be bound include: zoom, aperture, focus and exposure. Of course, the embodiment of the present application only specifically exemplifies the above functions, and does not limit the "counterclockwise rotation twice" instruction to only be bound to Fig.24 For example, click Fig.24 The “aperture” in the shooting preview screen 203 shown indicates that the “aperture” function is bound to the instruction of “rotate counterclockwise twice continuously”. When the mobile terminal opens the camera application, the user rotates the adjustment ring counterclockwise twice continuously, and the function to be adjusted is switched to “aperture”. The user can adjust the size of the “aperture” parameter by rotating the adjustment ring again.

[0174] Step 202: When the user rotates the adjustment ring, the mobile terminal obtains the rotation information of the adjustment ring.

[0175] After the user opens the camera application on the mobile terminal, the display screen of the mobile terminal displays a shooting preview screen. At this time, the user can hold the mobile terminal and aim the camera of the mobile terminal at the object to be photographed, and the shooting preview screen of the mobile terminal can display the image of the object to be photographed at this time. If the image at this time is not the image the user wants, the user can turn the adjustment ring to adjust the parameters in the image displayed in real time by the mobile terminal.

[0176] First, the user can select the function mode to be adjusted through the adjustment ring. The function mode may include the various modes in the function switching bar introduced above, for example, including mode 1: zoom, adjusting the focal length of the camera module; mode 2: exposure, adjusting the exposure during shooting; mode 3: aperture, adjusting the aperture size during shooting; mode 4: focus, adjusting the image distance during shooting, that is, adjusting the distance from the optical center of the lens in the camera module to the film plane; mode 5: mode switching, adjusting different modes during shooting; mode 6: picture level, adjusting the horizontality of the picture. The user can switch different function modes by rotating the adjustment ring twice in a clockwise direction, or rotating the adjustment ring twice in a counterclockwise direction. When the user switches to the desired (preset) function mode, the user can rotate the adjustment ring (once) to adjust the specific parameter size in the function mode. Taking aperture adjustment as an example, when the user switches the function mode to mode 3 by rotating the adjustment ring twice in a row, the user can adjust the specific aperture size by rotating the adjustment ring again.

[0177] Whether it is switching function modes or adjusting specific parameters, when the user uses the adjustment ring to operate, the adjustment ring collects the user's input and forms rotation information. The sensor in the mobile terminal detects the rotation information of the adjustment ring and converts the physical information of the adjustment ring, such as the rotation direction, rotation angle, number of rotations and rotation time, into corresponding electrical signals.

[0178] The rotation information includes the rotation time and number of rotations of the adjustment ring, as well as the direction information and angle information. The rotation time and number of rotations in the rotation information can be obtained to determine whether the adjustment ring rotates once or continuously. The adjustment ring rotates twice in a direction continuously, which means that the adjustment ring rotates twice in a direction within a preset time t, wherein the preset time t is a shorter time, for example, time t≤1s, which can be 1s, 0.5s, or 0.2s. When the adjustment ring rotates once, the direction information and angle information in the rotation information can be obtained.

[0179] Step 203: Determine an adjustment instruction corresponding to the rotation information.

[0180] Before rotating the adjustment ring to adjust the mobile terminal, the relationship between different rotation modes of the adjustment ring and the adjustment instructions can be defined, and the corresponding relationship between the rotation information corresponding to the different rotation modes and the adjustment instructions is stored in the memory of the mobile terminal. For example, it is defined that rotating the adjustment ring twice in a clockwise direction continuously is switched to the next functional mode; and it is defined that rotating the adjustment ring twice in a counterclockwise direction continuously is switched to the previous functional mode. It is defined that rotating the adjustment ring clockwise increases the parameter to be adjusted in the current functional mode, and it is defined that rotating the adjustment ring counterclockwise decreases the parameter to be adjusted in the current functional mode. And the corresponding relationship between the rotation information of the above-mentioned rotation modes of the adjustment ring and the defined adjustment instructions is pre-stored in the memory.

[0181] When the adjustment ring on the mobile terminal is rotated, the sensor in the mobile terminal obtains the rotation information of the adjustment ring and can send the obtained rotation information to the processor. The input end of the processor receives the electrical signal transmitted from the sensor, and the processor accesses the correspondence between the rotation information and the adjustment instruction pre-stored in the memory, and determines the specific adjustment instruction corresponding to the rotation information based on the correspondence.

[0182] For example, if the rotation information is that the adjustment ring rotates clockwise twice within the preset time t, the corresponding adjustment instruction is determined to be switching to the next functional mode; if the rotation information is that the adjustment ring rotates counterclockwise twice within the preset time t, the corresponding adjustment instruction is determined to be switching to the previous functional mode. If the rotation information is that the adjustment ring rotates clockwise, the corresponding adjustment instruction is determined to increase the parameter to be adjusted in the current functional mode; if the rotation information is that the adjustment ring rotates counterclockwise, the corresponding adjustment instruction is determined to decrease the parameter to be adjusted in the current functional mode.

[0183] It should be noted that it can also be defined as: if the rotation information is that the adjustment ring rotates counterclockwise, then the corresponding adjustment instruction is determined to be to increase the parameter to be adjusted in the current functional mode; if the rotation information is that the adjustment ring rotates clockwise, then the corresponding adjustment instruction is determined to be to decrease the parameter to be adjusted in the current functional mode.

[0184] Step 204: adjust the shooting preview image according to the adjustment instruction, and display the adjusted image on the display screen.

[0185] After receiving the adjustment instruction sent by the processor, the camera of the mobile terminal adjusts the parameters in the shooting preview screen according to the specific content of the adjustment instruction to meet the user's predetermined adjustment target. After the camera adjusts the preset screen according to the adjustment instruction, the adjusted screen is displayed on the display.

[0186] For example, when a user uses the camera application of a mobile terminal to take a photo, in the shooting preview screen, the current function mode is mode 1: focus. When the user rotates the adjustment ring twice in a clockwise direction, the processor generates an adjustment instruction to switch to the next function mode based on the rotation information detected by the sensor, and the processor sends the instruction to the camera. Then, in the camera's shooting preview screen, the current function mode switches from mode 1: focus to mode 2: exposure. And the current function mode is displayed as exposure in the current shooting preview screen.

[0187] If the user needs to adjust the exposure in the shooting preview screen at this time, he can turn the adjustment ring. When the user turns the adjustment ring clockwise, the sensor detects the rotation information of the adjustment ring. The processor generates a corresponding adjustment instruction based on the rotation information sent by the sensor and the corresponding relationship pre-stored in the memory: increase the parameter to be adjusted in the current functional mode. The camera then increases the exposure in the shooting preview screen according to the received adjustment instruction. When the user turns the adjustment ring counterclockwise, the sensor detects the rotation information of the adjustment ring. The processor generates a corresponding adjustment instruction based on the rotation information sent by the sensor and the corresponding relationship pre-stored in the memory: decrease the parameter to be adjusted in the current functional mode. The camera then decreases the exposure in the shooting preview screen according to the received adjustment instruction.

[0188] Correspondingly, when a user uses the camera application of a mobile terminal to take a photo, in the shooting preview screen, the current function mode is mode 2: exposure. When the user rotates the adjustment ring twice in a counterclockwise direction, the processor generates an adjustment instruction to switch to the previous function mode based on the rotation information detected by the sensor, and the processor sends the instruction to the camera. Then, in the camera's shooting preview screen, the current function mode switches from mode 2: exposure to mode 1: focus. And the current function mode is displayed as focus in the current shooting preview screen.

[0189] If the user needs to adjust the focal length in the shooting preview screen at this time, the user can turn the adjustment ring. When the user turns the adjustment ring clockwise, the sensor detects the rotation information of the adjustment ring, and the processor generates a corresponding adjustment instruction based on the rotation information sent by the sensor and the corresponding relationship pre-stored in the memory: increase the parameter to be adjusted in the current functional mode. The camera then increases the focal length in the shooting preview screen according to the received adjustment instruction. When the user turns the adjustment ring counterclockwise, the sensor detects the rotation information of the adjustment ring, and the processor generates a corresponding adjustment instruction based on the rotation information sent by the sensor and the corresponding relationship pre-stored in the memory: decrease the parameter to be adjusted in the current functional mode. The camera then decreases the focal length in the shooting preview screen according to the received adjustment instruction.

[0190] It should be noted that the user can judge whether the current picture reaches the user's predetermined goal based on the shooting preview picture displayed on the display screen. If the user's predetermined goal is achieved, the photo can be taken. If the user's predetermined goal is not achieved, steps 202-204 can be repeated, and different adjustment instructions can be generated by rotating the adjustment ring multiple times to achieve multiple adjustments to the shooting preview picture. For example, the user can switch the functional mode by rotating the adjustment ring twice in a row in one direction; and then adjust the parameter size in the functional mode by rotating the adjustment ring. By repeating the above two operations, the switching functional mode instruction and the parameter size adjustment instruction are continuously generated, and the parameter size in each functional mode in the shooting preview picture can be adjusted.

[0191] The present application embodiment provides a mobile terminal and a method for interacting with the mobile terminal. By setting an adjustment ring on the mobile terminal and interacting with the mobile terminal through the adjustment ring, the operation is convenient and can be operated with one hand. Moreover, by interacting through the adjustment ring, the rotation amount of the adjustment ring corresponds to the adjustment amount, so that fine adjustment can be achieved and the adjustment is more accurate. By using the adjustment ring for adjustment, there is no need to display a specific adjustment bar on the display screen of the mobile terminal. For example, there is no need to display the adjustment bar of the shooting preview screen when taking pictures and the adjustment instructions such as the magnification bar, so that the shooting preview screen is cleaner.
