Take a mobile terminal as an example. Fig. 1 is a block diagram illustrating a partial structure of a mobile phone according to an embodiment of the present disclosure. Referring to fig. 1, the cellular phone includes: a Radio Frequency (RF) circuit 110, a memory 120, an input unit 130, a display unit 140, a sensor 150, an audio circuit 160, a wireless fidelity (WiFi) module 170, a processor 180, and a power supply 190. Those skilled in the art will appreciate that the handset configuration shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
The following describes each component of the mobile phone in detail with reference to fig. 1:
the RF circuit 110 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 180; in addition, the data for designing uplink is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to global system for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.
The memory 120 may be used to store software programs and modules, and the processor 180 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 120. The memory 120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 130 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone 100. Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. The touch panel 131, also referred to as a touch screen, may collect touch operations of a user on or near the touch panel 131 (e.g., operations of the user on or near the touch panel 131 using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 131 may include two parts, i.e., a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 180, and can receive and execute commands sent by the processor 180. In addition, the touch panel 131 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 130 may include other input devices 132 in addition to the touch panel 131. In particular, other input devices 132 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 140 may be used to display information input by a user or information provided to the user and various menus of the mobile phone. The display unit 140 may include a display panel 141, and optionally, the display panel 141 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 131 can cover the display panel 141, and when the touch panel 131 detects a touch operation on or near the touch panel 131, the touch operation is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although the touch panel 131 and the display panel 141 are shown as two separate components in fig. 1 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 131 and the display panel 141 may be integrated to implement the input and output functions of the mobile phone.
The handset 100 may also include at least one sensor 150, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 141 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, detailed description is omitted here.
WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 170, and provides wireless broadband Internet access for the user. Although fig. 1 shows the WiFi module 170, it is understood that it does not belong to the essential constitution of the handset 100, and can be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 180 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby integrally monitoring the mobile phone. Alternatively, processor 180 may include one or more processing units; preferably, the processor 180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 180.
The handset 100 also includes a power supply 190 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 180 via a power management system to manage charging, discharging, and power consumption via the power management system.
Although not shown, the handset 100 may also include a camera. Optionally, the position of the camera on the mobile phone 100 may be front-located or rear-located, which is not limited in this embodiment of the application.
Optionally, the mobile phone 100 may include a single camera, a dual camera, or a triple camera, which is not limited in this embodiment.
For example, the cell phone 100 may include three cameras, one being a main camera, one being a wide camera, and one being a tele camera.
Optionally, when the mobile phone 100 includes a plurality of cameras, the plurality of cameras may be all front-mounted, all rear-mounted, or a part of the cameras front-mounted and another part of the cameras rear-mounted, which is not limited in this embodiment of the present application.
In addition, although not shown, the mobile phone 100 may further include a bluetooth module or the like, which is not described herein.
In an application scenario, when a user uses a mobile terminal to perform visible light communication with other devices, if a screen of the mobile terminal is in a bright screen state, the brightness of the screen of the mobile terminal may affect a visible light signal sent or received by the mobile terminal in the visible light communication process.
Specifically, fig. 2 shows a flowchart of a first brightness adjustment method provided in an embodiment of the present application, where the brightness adjustment method is applied to a mobile terminal, and includes:
in the embodiment of the application, after the mobile terminal is started, the user can input the visible light communication instruction to the mobile terminal, and then the visible light communication between the mobile terminal and other equipment is triggered. The other devices may be a smart phone, a tablet computer, a smart watch, or the like, which is not limited herein. Specifically, if the mobile terminal is required to transmit data to other devices, a user may select data to be transmitted and a corresponding "visible light transmission" virtual button by clicking on the screen of the mobile terminal, and input a visible light communication instruction to the mobile terminal, where names of the virtual buttons are only used as examples; or, if the mobile terminal is required to receive data transmitted by other devices, the user may input a visible light communication instruction to the mobile terminal through a preset operation on a designated key of the mobile terminal, where the designated key may be a combination of two or more existing physical keys of the mobile terminal, and the preset operation may be a short-press operation or a long-press operation, and the like, which is not limited herein.
Optionally, considering that the brightness of the screen of the mobile terminal affects the visible light communication between the mobile terminal and other devices only in the bright screen state, before step 201, the brightness adjustment method further includes:
detecting the screen state of the mobile terminal;
accordingly, the step 201 includes:
if the mobile terminal is in a bright screen state, when the mobile terminal receives the visible light communication instruction, detecting whether the brightness level of the screen of the mobile terminal exceeds a preset brightness level threshold value.
That is, only when the mobile terminal is in the bright screen state, the screen brightness of the mobile terminal is adjusted based on the visible light communication instruction, and when the mobile terminal is in the off screen state, the influence of the screen brightness on the visible light communication does not need to be considered. Specifically, when the mobile terminal is in the screen-off state, if the mobile terminal needs to perform visible light communication, a visible light signal may be emitted by a flash (as a transmitting end), and a visible light signal may be received by a rear camera (as a receiving end).
in the embodiment of the application, once the mobile terminal receives the visible light communication instruction, whether the brightness level of the screen of the mobile terminal exceeds a preset brightness level threshold value is detected immediately. The brightness level threshold may be set by the mobile terminal when the mobile terminal leaves the factory, or may be actively set by the user, which is not limited herein. Specifically, in consideration of reducing the influence of the brightness of the screen on the subsequent visible light communication, in the embodiment of the present application, the brightness level threshold may be set to a small value, for example, assuming that the brightness of the mobile terminal has 20 levels in total, the brightness level threshold may be set to 5 levels, which is merely an example.
in the embodiment of the present application, when it is detected that the brightness level exceeds the preset brightness level threshold, it is considered that the screen of the mobile terminal is too bright, which may possibly affect subsequent visible light communication, and based on this, the brightness of the screen needs to be adjusted, specifically, the brightness level of the screen is reduced, so that the adjusted brightness level of the screen does not exceed the brightness level threshold. Optionally, a target brightness level may be preset, and when the brightness level exceeds a preset brightness level threshold, the brightness level may be directly adjusted to the target brightness level; of course, the user may also manually fine-tune the brightness level of the screen after the mobile terminal automatically adjusts the brightness level of the screen, and update the brightness level obtained after the user manually fine-tunes to a new target brightness level.
And 204, triggering the mobile terminal to perform visible light communication with other equipment based on the visible light communication instruction.
In this embodiment of the application, after the brightness level of the screen is adjusted, the mobile terminal is triggered to perform visible light communication with other devices based on the visible light communication instruction, and specifically, according to the instruction of the visible light communication instruction, the mobile terminal may be used as a sending end of a visible light signal to send data to the other devices, or the mobile terminal may be used as a receiving end of the visible light signal to receive data sent by the other devices. Further, before the visible light communication starts, and after the visible light communication ends, the mobile terminal may output a corresponding voice alert message, for example, before the visible light communication starts, the mobile terminal may output "receive a visible light signal by a front camera (or a rear camera) after x seconds" or "send a visible light signal by a flash (or a light source area of a screen) after x seconds" in a voice; after the end of the visible light communication, the mobile terminal may output "the visible light communication is ended this time" in a voice.
Optionally, when the brightness level exceeds a preset brightness level threshold, the brightness adjusting method further includes:
recording the current brightness level of the mobile terminal as an original brightness level;
after the brightness level of the screen is adjusted, the brightness adjusting method further includes:
and when the mobile terminal finishes the visible light communication, restoring the brightness level of the screen to the original brightness level.
In the embodiment of the present application, in order to avoid affecting the normal use of the mobile terminal by the user and avoid that the user manually adjusts the brightness level of the screen before and after the visible light communication is performed by the mobile terminal, when the brightness level exceeds a preset brightness level threshold, the current brightness level of the mobile terminal may be recorded in a cache area of the mobile terminal, and the current brightness level may be marked as the original brightness level. Once the subsequent visible light communication is finished, the brightness level of the screen can be immediately restored to the original brightness level, so that the mobile terminal returns to the screen brightness before being dimmed, and the user can conveniently continue to use the mobile terminal normally.
Therefore, in the embodiment of the application, after the mobile terminal receives the visible light communication instruction, the brightness level of the screen of the mobile terminal is detected, when the screen of the mobile terminal is too bright, the brightness of the screen of the mobile terminal is reduced, and then the operation of the mobile terminal for performing visible light communication with other equipment is triggered based on the received visible light communication instruction, so that the influence of the brightness emitted by the screen of the mobile terminal on the visible light communication between the mobile terminal and other equipment is reduced.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
In another embodiment, the mobile terminal may perform different operations according to a communication role in which the mobile terminal is located in the visible light communication process, for example, the mobile terminal may be a receiving end for visible light communication, and receive a visible light signal sent by another device; alternatively, the apparatus may be configured to transmit a visible light signal to another device as a transmitting end of visible light communication. Based on this, fig. 3 shows a flowchart of a second brightness adjustment method provided in the embodiment of the present application, where the brightness adjustment method is applied to a mobile terminal, and includes:
in step 301, detecting whether the mobile terminal receives a visible light communication instruction;
in step 302, when the mobile terminal receives the visible light communication command, detecting whether a brightness level of a screen of the mobile terminal exceeds a preset brightness level threshold;
in the embodiment of the present application, the steps 301 and 302 are respectively the same as the steps 201 and 202, and reference may be specifically made to the implementation flows of the steps 201 and 202, which are not described herein again.
In step 303, if the brightness level exceeds a preset brightness level threshold, analyzing the visible light communication command, and determining a communication role of the mobile terminal in the process of the visible light communication;
in the embodiment of the present application, the visible light communication command indicates a communication role played by the mobile terminal in a subsequent visible light communication process, where the communication role includes a sending end and a receiving end. The transmitting end is used for transmitting visible light signals to other equipment, and the receiving end is used for receiving the visible light signals transmitted by the other equipment.
In step 304, if the mobile terminal is the transmitting end of the visible light communication, determining a light source of the transmitting end based on the visible light communication command;
in step 305, if the mobile terminal is a receiving end of the visible light communication, determining a receiver of the receiving end based on the visible light communication command;
in the embodiment of the present application, the visible light communication instruction indicates, in addition to the communication role, a component that is enabled by the mobile terminal in the following visible light communication process. For example, when the mobile terminal is used as a transmitting end, a flash lamp may be used as a light source, and a screen may also be used as a light source, which is not limited herein. Specifically, in order not to affect the normal use of the mobile terminal in the visible light communication process, when the screen is used as the light source, only a small area of the screen is often used as the light source, and as shown in fig. 4, the screen is divided into a light source area and other areas. When the mobile terminal is used as a receiving end, the front-facing camera can be used as a receiver, and the rear-facing camera can also be used as a receiver.
In step 306, determining a screen brightness adjustment area associated with the visible light communication according to the light source or the receiver;
specifically, when the light source is a screen light source, a light source region may be defined based on a position of the light source on a screen, wherein the light source region includes only the light source, and then other regions on the screen except the light source region may be determined as a screen brightness adjustment region. That is, the light source area in fig. 4 is not adjusted because the light source is included in this area. Specifically, when the visible light signal is sent through the light source area, the mobile terminal preprocesses data to be transmitted, performs coding modulation, finally drives the LED element in the light source area to modulate the brightness of the LED element, converts the electrical signal into an optical signal, and sends the optical signal out, so as to send the visible light. That is, the brightness of the light source region is determined based on the data to be transmitted during the visible light communication. Of course, when the flash lamp is used as the light source, the process of sending the visible light signal is similar to the process of sending the visible light signal through the screen light source, and the details are not repeated here. It should be noted that, in the process of sending the visible light signal to the outside in the light source region, the screen brightness adjustment region will keep working normally, for example, if the mobile terminal originally plays a video, after starting the visible light communication, the light source region sends visible light to the outside based on the data to be transmitted, and the brightness of the light source region dynamically changes based on the data to be transmitted; and the screen brightness adjusting area continuously keeps normal video playing, only the brightness during video playing is reduced, and the brightness level of the screen brightness adjusting area is kept unchanged under the condition that a user does not perform manual fine adjustment. That is, during the process of visible light communication, the display content of the screen brightness adjusting area is not changed.
Specifically, when the receiving end is a front-facing camera, considering that the screen and the front-facing camera are located on the same side of the mobile terminal, the screen brightness of the mobile terminal may still interfere with the reception of the visible light signal of the front-facing camera to a certain extent.
Specifically, when the mobile terminal is a transmitting terminal and the light source is a flash lamp, or when the mobile terminal is a receiving terminal and the receiving terminal is a rear camera, the flash lamp and the rear camera are not located on the same side of the mobile terminal as the screen, so that the influence of screen brightness on the flash lamp and the rear camera is small, and at this time, the brightness level of the screen may not be adjusted.
In step 307, adjusting the brightness level of the screen brightness adjusting area;
in step 308, the mobile terminal is triggered to perform visible light communication with other devices based on the visible light communication command.
In the embodiment of the present application, the steps 307 and 308 are similar to the steps 203 and 204, respectively, and reference may be specifically made to the implementation flows of the steps 203 and 204, which are not described herein again.
As can be seen from the above, in the embodiment of the present application, after the mobile terminal receives the visible light communication instruction, the brightness level of the screen of the mobile terminal is detected, when the screen of the mobile terminal is too bright, the corresponding screen brightness adjustment area is determined based on the communication role played by the mobile terminal in the subsequent visible light communication process and the enabled component, and the brightness of the screen brightness adjustment area is reduced, and then the operation of visible light communication between the mobile terminal and other devices is triggered based on the received visible light communication instruction, so as to reduce the influence of the brightness emitted by the screen of the mobile terminal on the visible light communication between the mobile terminal and other devices.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
