Description

Mobile terminal screen control method and mobile terminal

Technical field

The present invention relates to the field of mobile terminals, and in particular, to a mobile terminal screen control method and a mobile terminal.

Background technique

Due to the development of mobile terminals, it integrates more and more functions, among which the more prominent one is the shooting function of the mobile terminal. In order to enable users to obtain a better shooting experience through mobile terminals, in recent years, manufacturers of major mobile terminals have made tremendous improvements in the shooting effect of the camera. Therefore, the shooting effect of the mobile terminal is now available with some cameras. It is quite beautiful. Because of this, mobile terminals are more portable and more popular than professional cameras. Therefore, this promotes the tendency of ordinary people to abandon professional cameras when they go out and choose to use mobile terminals for shooting.

In the conventional shooting mode, the user controls the mobile terminal with his hand to adjust the shooting distance and shooting angle, but due to the limitation of the length of the limb and the height, it is difficult to achieve the shooting with the best shooting distance and shooting angle. Especially when the user is taking self-portrait or taking pictures, it is very inconvenient. Therefore, the self-timer rod specially shot for the mobile terminal comes into being. The selfie stick is a convenient self-timer tool, which changes the traditional shooting mode for the user. Provides a good shooting experience.

As shown in FIG. 1, the self-timer 11 currently produced and sold on the market generally includes a telescopic rod 112 and a clamping structure 111. The clamping structure 111 is connected to one end of the rod 112 for fixing the mobile terminal 10 and the rod 112. The other end is provided with a shooting button 113. When the user performs photographing using the self-timer lever 11, the user holds the self-timer lever 11 and is provided with one end of the photographing button 113, and adjusts the self-timer lever 11 to the extended state, so that the rod body 112 of the self-timer lever is extended and lengthened, and the self-timer lever body is utilized. The extension of 112 increases the distance between the mobile terminal 10 and the object to be photographed, thereby expanding the viewing range, and facilitating the user to select the shooting angle.

Although the appearance of the selfie stick has greatly improved the user's shooting experience, there are still some shortcomings: after the user takes a picture or turns on the photo preview mode, the phone screen is The currently previewed image will be displayed in real time, and this process will consume a lot of power. At present, in order to meet the portability requirements of mobile terminals, mobile terminals do not store a lot of energy. For users who go out to play, it is not portable with too many energy storage devices, so the best practice is to let the mobile terminal turn on the shooting preview mode when the user needs to shoot, and when the user finishes shooting or does not need to shoot. , then close the preview and enter the information screen to save energy. However, since the mobile terminal is clamped by the clamping structure at a distance from the user, when the user needs to perform a bright screen or a screen operation on the mobile terminal, the user not only needs to retract the mobile terminal from the self-timer to the nearer one. Place, but also press the button under the constraints of the clamping structure. This is very inconvenient, especially when the user needs to take a snapshot, this control method can not meet the time requirements at all, it is easy for the user to miss the picture that he desires to shoot.

detailed description

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

Embodiment 1:

In order to solve the technical problem that the user is inconvenient to control the screen when the mobile terminal is clamped on the self-timer in the prior art, the embodiment provides a screen control method for the mobile terminal, as shown in FIG. 2:

S202. The mobile terminal receives a control signal sent by the selfie stick.

After the selfie stick establishes a communication connection with the mobile terminal, the selfie stick can send a control signal to the mobile terminal by wire or wirelessly. If the selfie stick transmits control signals wirelessly, the communication can be performed in various ways, for example, the self-timer lever performs infrared communication with the mobile terminal or performs ultrasonic communication and radio frequency communication. At present, the commonly used methods of radio frequency communication include Bluetooth communication, WIFI communication, or near field communication. Considering that the use scene of the selfie stick is basically outdoors, the mobile terminal and the selfie stick in this embodiment are not used temporarily. WIFI communication, but it should be understood by those skilled in the art that if in a WIFI environment, the mobile terminal in this embodiment can also communicate with the self-timer using WIFI communication.

In the field of short-range signal transmission, Bluetooth communication is more versatile than other communication methods, and Bluetooth communication has lower power consumption. On the other hand, the current Bluetooth communication technology is mature, and its requirements for signal transceiving equipment are low. Almost all mobile terminals can implement Bluetooth transmission. Therefore, in this embodiment, the mobile terminal can also communicate with the selfie stick. Via Bluetooth, Bluetooth communication uses a microwave radio spectrum of 2.402 GHz to 2.480 GHz.

If the selfie stick sends a control signal to the mobile terminal by wire, the control signal is usually in the form of an electrical signal, and the voltage value, current value, and the like of the electrical signal can be used to reflect the purpose of the user transmitting the control signal through the selfie stick.

S204. The mobile terminal determines that the control signal is a screen control signal for controlling a state of the screen.

Since the control of the mobile terminal may be divided into multiple types, in addition to controlling the state of the screen of the mobile terminal, other controls are also included, such as controlling the volume adjustment of the mobile terminal, controlling the mobile terminal to perform shooting, or controlling the camera switching of the mobile terminal. .

Therefore, after the mobile terminal receives the control signal, it is necessary to determine whether the control signal is a screen control signal for controlling the state of the screen. For the wireless communication mode, there are many ways to distinguish the screen control signal from other control signals. For example, the screen control signal is different from the content of the data carried in other control signals, and the format is different.

For the control signal transmitted by the wired mode, the voltage value or current value of the electrical signal that can be sent to the mobile terminal through the selfie stick is reflected by the user's control purpose, so if the control signal received by the mobile terminal is transmitted by wire, That is, the control signal is sent in the form of an electrical signal. When determining whether the control signal is a screen control signal, the current value or the voltage value of the electrical signal can be transmitted according to the self-timer lever. Specifically, whether the current value is used or not It is determined by the magnitude of the voltage value that the mobile terminal and the self-timer can agree in advance. After the agreement is completed, the self-timer generates a corresponding electrical signal according to the agreement, and the mobile terminal performs corresponding analysis or detection on the signal sent by the selfie stick according to the agreement.

In this embodiment, the mobile terminal determines whether the control signal is a screen control signal according to a voltage value of the electrical signal transmitted by the selfie stick. If the voltage value of the electrical signal is stable within a preset time and the mobile terminal is currently in the shooting preview state, it is determined that the electrical signal is a screen control signal, that is, the user transmits the electrical signal through the selfie stick for the screen of the mobile terminal. The status is controlled. Inside the memory of the mobile terminal, a mapping relationship between various control operations performed on the mobile terminal and voltage values of the corresponding control signals is stored in advance, for example, a voltage value of a control signal corresponding to the control of the volume of the mobile terminal is assumed. 1.2V, then when the mobile terminal detects the current control When the voltage value of the signal is 1.2V, the output volume of the mobile terminal is controlled when the user currently wants to perform an operation.

In an example of the embodiment, the selfie stick forms a communication connection with the mobile terminal through an audio input and output interface provided on the mobile terminal, and the user controls the screen state of the mobile terminal by long pressing the shooting button set on the selfie stick. Since the volume control of the mobile terminal is also performed by long pressing the button on the remote control headset, for the mobile terminal, it is impossible to distinguish whether the currently inserted audio input/output interface is a wired headset or a selfie stick, and therefore, when the mobile terminal detects When a voltage value of a long time continues and the voltage value is 1.2V, the mobile terminal incorrectly adjusts the volume of the mobile terminal according to the mapping relationship between the 1.2V and the volume adjustment operation. Although in the present embodiment, the mobile terminal detects a continuous voltage of 1.2 V while the mobile terminal is in the shooting preview state, and the control signal of the volume adjustment is not issued in the shooting preview state, although the mobile terminal determines the current The user does not want to adjust the volume of the mobile terminal, but because it is limited by the influence of the predetermined program, the corresponding volume control operation can only be performed based on the detected voltage value.

In order to solve the problem in the above example, in the present embodiment, the mapping relationship between the screen state control and the preset control voltage value is stored in advance in the mobile terminal. For example, the voltage value of the electric signal corresponding to the screen state control is set to 1.5V. When the mobile terminal detects the voltage value of 1.5V, the screen state is controlled according to the preset mapping relationship, thereby avoiding the error basis of the mobile terminal. The problem of the screen control signal controlling the volume. On the basis of this, when the mobile terminal determines that the control signal is a screen control signal, the voltage value of the screen control signal is adjusted to a preset control voltage value, such as when the mobile terminal detects the self-timer through the shooting button in the shooting preview state. When the 1.2V voltage signal is sent, it is necessary to adjust the voltage of 1.2V to 1.5V.

After the voltage value of the screen control signal is adjusted to the voltage value corresponding to the screen state control that the mobile terminal can recognize, the mobile terminal can control the screen state of the mobile terminal according to the voltage value. In the solution provided by the embodiment, although the voltage values of the previous volume control and the screen state control signal are the same, the volume control is separated from the screen state control by the voltage value adjustment means before the mobile terminal is controlled, so that the mobile terminal The volume control and screen state control do not affect each other, improving the user experience.

S206. The mobile terminal controls the state of the screen based on the current state of the screen.

After receiving the screen control signal, determine whether the screen is in the current state or the screen state. If the screen is currently in the bright state, the screen is switched to the screen state, otherwise the screen is switched from the screen state to the screen. status.

The mobile terminal in this embodiment may be in various forms, for example, a mobile phone, a PDA (Personal Digital Assistant), a PAD (portable android device), a PMP (Portable Media Player), and a portable multimedia player. And so on.

According to the mobile terminal screen control method provided by the embodiment of the present invention, the screen control of the mobile terminal by the user is expected to be reflected by the screen control signal sent by the self-timer to the mobile terminal, and the mobile terminal transmits the self-timer rod by wire or wirelessly. After the screen control signal, the state of the screen can be adjusted based on the current state of the screen, thereby avoiding the inconvenience caused by the mobile terminal retracting from the selfie stick and then operating through the button, thereby improving the user experience, and at the same time, The user can conveniently adjust the screen brightness of the mobile terminal according to his own needs at any time, thereby reducing the energy consumption of the mobile terminal.

Embodiment 2:

In order to implement the mobile terminal screen control method provided in the first embodiment, the embodiment provides a mobile terminal, as shown in FIG. 3:

In this embodiment, the mobile terminal 30 includes a receiving module 302, a parsing module 304, and a control module 306.

The receiving module 302 is arranged to receive a control signal transmitted by the selfie stick. After the selfie stick establishes a communication connection with the mobile terminal 30, the selfie stick can transmit a screen control signal to the receiving module 302 of the mobile terminal 30 by wire or wirelessly. If the selfie stick transmits the screen control signal wirelessly, the manner of communication includes various types, for example, the selfie stick performs infrared communication with the mobile terminal 30 or performs ultrasonic communication and radio frequency communication. At present, the commonly used methods of radio frequency communication include Bluetooth communication, WIFI communication, or near field communication. Considering that the use scene of the selfie stick is basically outdoors, the receiving module 302 and the selfie stick in this embodiment are not temporarily Use WIFI communication, but those skilled in the art should understand that if in a WIFI environment, this implementation The receiving module 302 in the example can also communicate with the selfie stick by WIFI communication.

In the field of short-range signal transmission, Bluetooth communication is more versatile than other communication methods, and Bluetooth communication has lower power consumption. On the other hand, the Bluetooth communication technology is mature, and the requirements for the signal transceiving device are low. Almost all the mobile terminals 30 can implement Bluetooth transmission. Therefore, in this embodiment, the receiving module 302 can also be connected with the selfie stick. The communication is carried out via Bluetooth, and the Bluetooth communication uses a microwave radio spectrum of 2.402 GHz to 2.480 GHz.

If the self-timer lever sends a screen control signal to the receiving module 302 by wire, the screen control signal is usually in the form of an electrical signal, and the voltage value, current value, and the like of the electrical signal can be used to reflect that the user transmits the screen control signal through the selfie stick. the goal of.

The parsing module 304 is arranged to determine that the control signal is a screen control signal for controlling the state of the screen. Since the control of the mobile terminal 30 by the selfie stick may be divided into various types, in addition to controlling the state of the screen of the mobile terminal 30, other controls, such as controlling the volume adjustment of the mobile terminal, controlling the mobile terminal 30 to take a picture, or controlling The camera of the mobile terminal 30 is switched.

Therefore, after the receiving module 302 receives the control signal, the parsing module 304 needs to determine whether the control signal is a screen control signal for controlling the state of the screen, and for the wireless communication mode, distinguish the screen control signal from other control signals. There are many ways, for example, the screen control signal is different from the content of the data carried in other control signals, and the format is different.

The control signal transmitted by the wired mode can be embodied by the voltage value or the current value of the electrical signal transmitted by the self-timer to the mobile terminal, so that the control signal received by the receiving module 302 is transmitted by wire. , that is, the control signal is sent in the form of an electrical signal, and the parsing module 304 determines whether the control signal is a screen control signal, and may perform the current value or the voltage value of the electrical signal according to the self-timer lever. Specifically, the current value is used. The size of the voltage value is determined by the magnitude of the voltage value. The mobile terminal 30 and the self-timer bar can be pre-agreed. After the agreement is completed, the self-timer generates a corresponding electrical signal according to the agreement, and the parsing module 304 responds to the signal sent by the self-timer according to the agreement. Resolution or detection.

In this embodiment, the parsing module 304 determines whether the control signal is a screen control signal according to a voltage value of the self-picking rod transmitting electrical signal. If the voltage value of the electrical signal is stable within the preset time and the mobile terminal 30 is currently in the shooting preview state, the parsing module 304 determines that the electrical signal is a screen control signal, that is, the user transmits the electrical signal through the selfie stick. The screen state of the mobile terminal 30 is controlled. Inside the memory of the mobile terminal 30, a mapping relationship between various control operations performed on the mobile terminal 30 and voltage values of corresponding control signals is stored in advance, for example, assuming a control signal corresponding to the volume control of the mobile terminal 30 The voltage value is 1.2V, then when the mobile terminal 30 detects that the current control signal has a voltage value of 1.2V, the parsing module 304 determines the output volume of the mobile terminal 30 when the user currently wants to perform an operation.

In an example of the embodiment, the selfie stick forms a communication connection with the mobile terminal 30 through an audio input/output interface provided on the mobile terminal 30, and the user presses the shooting button set on the self-timer lever to the screen state of the mobile terminal 30. Take control. Since the volume control of the mobile terminal 30 is also performed by long pressing the button on the remote control headset, for the parsing module 304, it is impossible to distinguish whether the currently inserted audio input/output interface is a wired headset or a selfie stick, and therefore, when receiving the module When 302 detects a long-lasting voltage value and the voltage value is 1.2V, the control module 306 erroneously adjusts the volume of the mobile terminal 30 according to the mapping relationship between the 1.2V and the volume adjustment operation. Although in the present embodiment, the receiving module 302 detects a continuous voltage of 1.2V in a state where the mobile terminal 30 is in the shooting preview state, and the control signal of the volume adjustment is not issued in the shooting preview state, The module 304 determines that the current user does not want to adjust the volume of the mobile terminal 30, but because of the limitations of the established program, the control module 306 can only perform the corresponding volume control operation based on the detected voltage value.

In order to solve the problem in the above example, the embodiment further provides a mobile terminal. Referring to FIG. 4, the mobile terminal 30 includes a receiving module 302, a parsing module 304, and a control module 306, and further includes a storage module 308 and an adjusting module 310. The storage module 308 pre-stores a mapping relationship between the screen state control and the preset control voltage value. For example, the voltage value of the electric signal corresponding to the screen state control is set to 1.5V, and when a voltage value of 1.5V is detected, it is based on the pre- The mapping relationship is performed to control the state of the screen, and the problem that the mobile terminal 30 erroneously controls the volume according to the screen control signal is avoided. On the basis of this, when the mobile terminal 30 determines that the control signal is a screen control signal, the adjustment module 310 adjusts the voltage value of the screen control signal to a preset control voltage value, such as detecting the self-timer through the shooting preview state. When the button sends a voltage signal of 1.2V, the adjustment module 310 needs to adjust the voltage value of 1.2V to 1.5V.

After the voltage value of the screen control signal is adjusted by the adjustment module 310 to the voltage value corresponding to the screen state control that the analysis module 304 can recognize, the control module 306 can control the screen state of the mobile terminal 30 according to the voltage value. In the solution provided by the embodiment, although the voltage values of the previous volume control and the screen state control signal are the same, the volume control is separated from the screen state control by the voltage value adjustment means before the mobile terminal 30 is controlled, so that the movement is performed. The volume control of the terminal 30 and the control of the screen state do not affect each other, improving the user experience.

After receiving the screen control signal, the control module 306 determines whether the screen is in the current state or the screen state. If the screen is currently in the bright state, the screen is switched to the screen state, otherwise the control module 306 takes the screen from the information. The screen state switches to the bright screen state.

The mobile terminal 30 in this embodiment may be in various forms, for example, a mobile phone, a PDA (Personal Digital Assistant), a PAD (portable android device), a PMP (Portable Media Player, portable multimedia). Player) and so on.

The receiving module 302 can be implemented by the communication module of the mobile terminal, and the functions of the parsing module 304 and the control module 306 can be implemented by the processor, and the communication module of the mobile terminal receives the control that the self-timer is sent by wire or wirelessly. After the signal, the processor determines that the control signal is a screen control signal that controls the state of the screen, and then controls the bright screen or the interest screen of the mobile terminal based on the current state of the screen.

In the mobile terminal provided by the embodiment of the present invention, the screen control signal that the user desires for the mobile terminal can be reflected by the screen control signal sent by the self-timer to the mobile terminal, and the screen control signal sent by the mobile terminal by receiving the self-timer rod by wire or wirelessly After that, the state of the screen can be adjusted based on the current state of the screen, avoiding the mobile terminal being retracted from the selfie stick. After the inconvenience caused by the button operation, the user experience is improved.

Embodiment 3:

In this embodiment, a mobile terminal is taken as a smart phone as an example, and a supplementary description including more details is provided. Please refer to FIG. 5:

The smartphone 50 includes a processor 501 and a signal transmission unit 502. The signal transmission unit 502 is capable of receiving a control signal transmitted by an external device, which of course also includes a shooting control signal and a screen control signal transmitted by the selfie stick. The processor 501 can parse the control signal received by the signal transmission unit 502. When the processor 501 determines the control signal received by the signal transmission unit 502 for parsing, the signal is found to be a screen control signal for controlling the state of the screen. Then, the processor 501 controls the state of the screen according to the screen control signal.

In this embodiment, the state control of the screen includes controlling the smart phone 50 to be bright or visible. When going out to play, if the user uses the selfie stick, the smartphone 50 may be fixed on the selfie stick by the grip structure of the selfie stick most of the time, so if the user wants to press the button on the smartphone 50 It will be quite troublesome to operate. In the process of playing, the user will only have shooting requirements in a small amount of time, and most of the time, the screen of the smartphone 50 can be in the state of interest screen to reduce power consumption, but if the user ends at each shooting After that, the smart phone 50 is retracted from the selfie stick to perform the screen operation, which greatly affects the user experience, and especially when the user needs to capture a scene in the game, and the scene is slightly At this time, if the user has to take the smartphone 50 back from the far end of the selfie stick to perform a bright screen operation, then the user may have the best shooting opportunity. In the smart phone 50 provided by the embodiment, the signal transmission unit 502 can receive the control signal sent by the user from the selfie stick, and the processor 501 can determine the current screen state of the smart phone 50 after determining that the control signal is the screen control signal. Controlling the state of the screen, if the smart phone 50 is currently in the bright state, it indicates that the user currently sends the screen control signal to realize the information screen of the smart phone, and conversely, if the current screen state is in the interest screen state, the user is expected to pass the screen. The screen control signal causes the smartphone 50 to be in a bright screen state, and this solution solves the above problems and improves the user experience.

The self-timer lever used by the user can communicate with the smart phone 50 through Bluetooth, near field communication, ZigBee, etc. It is undoubted that the communication between the selfie stick and the smart phone can also be realized by wire. Compared with wireless self-timer bars such as Bluetooth, the wired connection of the selfie stick has been welcomed by the majority of users because of its low price, and the penetration rate is higher. Therefore, in order to make those skilled in the art more aware of the advantages of the mobile terminal provided by the embodiment, how to control the information screen and the bright screen of the smart phone 50 will be described below.

In the smart phone 50 used with the wired selfie stick, the control signal received by the signal transmission unit 502 is an electrical signal, and the processor 501 determines that the voltage value of the electrical signal is stable within a preset time and the current smart phone 50 is in the shooting. When the state is previewed, it is determined that the control signal is a screen control signal.

In this embodiment, since most of the wired selfie sticks are connected to the smart phone 50 through the audio input and output interface of the smart phone, the connection through the audio input and output interface may cause the processor 501 to be in accordance with the voltage of the electrical signal. When the value controls the screen state of the smartphone 50, the normal use of the smartphone 50-wired headset is affected. Therefore, in an example of the embodiment, as shown in FIG. 6, the smartphone 50 further includes a memory 503 and Signal adjustment unit 504.

In the memory 503, a mapping relationship between the screen state control and the preset control voltage value is stored in advance, and in one example, the various operations performed on the smartphone 50 are pre-stored in the memory 503 in the form of a table and Corresponding control voltage value of the control signal, it can be understood that the voltage value corresponding to the operation of the screen state control should be distinguishable from the voltage value corresponding to the control signal of other operation control, that is, the voltage value is different from the memory 503. Other voltage values in the saved table.

The signal adjustment unit 504 is configured to adjust the voltage value of the screen control signal after the processor 501 determines that the control signal is the screen control signal. Before the adjustment, the voltage value of the screen control signal may be the voltage value of the volume control signal. The same as the larger, but the adjusted voltage value will be compared with the preset control voltage value corresponding to the screen state control stored in the memory 503 table. Then, after the processor 501 detects the preset voltage value, the state of the screen is controlled according to the mapping relationship.

The smart phone provided by the audio input/output interface and the wired self-timer lever provided in this embodiment is described below with reference to a specific circuit diagram:

In this embodiment, a resistance control unit 701 is added to the motherboard of the smartphone, as shown in FIG. Normally, the power supply of the resistor unit 701 is turned off by the processor 501 of the smartphone 50.

When the user short presses the shooting button on the selfie stick, the switch S2 is closed, and the processor 501 detects that the MIC (microphone) signal has a voltage value, and the magnitude of the voltage value is:

V _MIC1 =V _BIAS /(R1+R3)*R3;

When the user presses the camera button on the selfie stick, the MIC (microphone) signal has a stable voltage value. When the processor 501 is delayed, the MIC signal can be detected to have a voltage value of V _{MIC_P} , and the processor 501 The resistor unit 701 is opened in software via a GPIO (General Purpose Input Output) port to change the voltage value of the MIC signal. The magnitude of the changed voltage value is:

V _MIC2 =V _BIAS /(R1//R+R3)*R3;

On the mobile terminal side, the function of the light/screen is given, so when the processor 501 detects the V _MIC2 , the state of the screen is changed: if the current screen is in the bright state, the control screen enters the information state. If the current screen is in the interest screen state, it is controlled to be in a bright screen state.

In this embodiment, the additional resistor unit 701 is used, and the self-timer shooting button has the function of the quantity/interval screen according to different voltage values on the MIC signal, instead of directly passing the software when detecting the voltage value on the MIC signal. The method is to turn off or turn on the LCD (Liquid Crystal Display), mainly because the volume is changed when the button is pressed and pressed. If the software controls the brightness or the screen through this voltage value, it may affect the normal control of the phone. The use of headphones.

In this embodiment, the resistor R1 implements the function of the signal transmission unit 502. After the resistor R1 is connected to the self-timer lever, the processor 501 can detect the voltage value on the MIC, and the resistance control The unit 701 implements the function of the signal adjustment unit 504, which is not shown in FIG.

The process of controlling the information screen and the bright screen of the screen of the mobile terminal by the shooting button of the selfie stick in the embodiment is described below with reference to FIG. 8 :

S801. Check whether the voltage value of the MIC signal is detected.

If yes, execute S802, when it is, it indicates that the user has pressed the shooting button, otherwise there is no button operation.

S802, whether the voltage value of the MIC signal can be detected after the delay.
