Specifically, the input unit 130 may include a touch screen 131 (optional) and / or other input devices 132. The touch screen 131 can collect the user's touch operations on or near it (such as the user's operation on or near the touch screen using any suitable object such as fingers, joints, stylus, etc.), and drive the corresponding connection device according to a pre-set program.

In the embodiment of the present application, the display unit 140 can be used to display the interface of the in-vehicle light parameters and / or screen display parameters, processing results, etc.

[0061] The memory 120 can be used to store instructions and data. The memory 120 can mainly include an instruction storage area and a data storage area.

It is also used for the storage of multimedia files, and the storage of running programs and applications.

[0062] The processor 170 is the control center of the terminal 100. It uses various interfaces and lines to connect various parts of the entire terminal 100. By running or executing instructions stored in the memory 120 and calling data stored in the memory 120, it executes various functions of the terminal 100 and processes data, thereby controlling the terminal device as a whole. Optionally, the processor 170 may include one or more processing units; preferably, the processor 170 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface and application program, and the modem processor mainly processes wireless communication. It is understandable that the above-mentioned modem processor may not be integrated into the processor 170. In some embodiments, the processor and the memory may be implemented on a single chip, and in some embodiments, they may also be implemented separately on separate chips. The processor 170 may also be used to generate corresponding operation control signals, send them to corresponding components of the computing and processing device, read and process data in the software, especially read and process data and programs in the memory 120, so that each functional module therein performs corresponding functions, thereby controlling the corresponding components to act according to the requirements of the instructions.

[0063] The radio frequency unit 110 (optional) can be used for receiving and sending information or receiving and sending signals during a call, for example, after receiving the downlink information of the base station, it is sent to the processor 170 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (Low Noise Amplifier, LNA), a duplexer, etc. In addition, the radio frequency unit 110 can also communicate with network devices and other devices through wireless communication.

[0064] In this embodiment of the present application, the RF unit 110 can send the user's eye feature data to the server 200, and receive the in-vehicle light parameters and / or screen display parameters sent by the server 200.

[0065] It should be understood that the radio frequency unit 110 is optional and can be replaced by other communication interfaces, such as a network port.

[0066] The terminal 100 also includes a power supply 190 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 170 through a power management system, so that the power management system can manage functions such as charging, discharging, and power consumption.

[0067] The terminal 100 further includes an external interface 180 , which may be a standard Micro USB interface or a multi-pin connector, and may be used to connect the terminal 100 to communicate with other devices, or to connect a charger to charge the terminal 100 .

Some or all of the methods described below may be applied in the following embodiments. Figure 2 In the terminal 100 shown.

[0069] Next describe Figure 1 The product form of the server 200;

[0070] Figure 3 A structural diagram of a server 200 is provided, such as Figure 3 As shown, the server 200 includes a bus 201, a processor 202, a communication interface 203, and a memory 204. The processor 202, the memory 204, and the communication interface 203 communicate with each other via the bus 201.

[0071] The bus 201 may be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 3 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0072] The processor 202 may be any one or more of a central processing unit (CPU), a graphics processing unit (GPU), a microprocessor (MP), or a digital signal processor (DSP).

[0073] The memory 204 may include a volatile memory, such as a random access memory (RAM). The memory 204 may also include a non-volatile memory, such as a read-only memory (ROM), a flash memory, a hard disk drive (HDD), or a solid state drive (SSD).

[0074] Among them, the memory 204 can be used to store software codes related to the user vision protection method, the processor 202 can execute the steps of the user vision protection method of the chip, and can also schedule other units to implement corresponding functions.

[0075] It should be understood that the above-mentioned terminal 100 and server 200 can be centralized or distributed devices, and the processors in the above-mentioned terminal 100 and server 200 (such as processor 170 and processor 202) can be hardware circuits (such as application specific integrated circuit (ASIC), field-programmable gate array (FPGA), general-purpose processor, digital signal processor (DSP), microprocessor or microcontroller, etc.), or a combination of these hardware circuits. For example, the processor can be a hardware system with an instruction execution function, such as a CPU, DSP, etc., or a hardware system without an instruction execution function, such as an ASIC, FPGA, etc., or a combination of the above-mentioned hardware systems without an instruction execution function and hardware systems with an instruction execution function.

[0076] At present, the adjustment of most vehicle-mounted screens is only for the screen itself, and the screen brightness is mainly adjusted based on ambient light, time changes, etc. The adjustment is limited to the screen itself and cannot guarantee the user's overall visual comfort. In addition, different users have different perceptions of screen brightness, and there is a lack of consideration for user personalized needs.

[0077] In order to solve the above problems, the embodiment of the present application provides a method for protecting user vision. The method for protecting user vision of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0078] Reference Figure 4 , Figure 4 A schematic diagram of a user vision protection method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, a user vision protection method provided in an embodiment of the present application may include steps 401 to 403, and these steps are described in detail below.

[0079] 401. Determine whether the eye feature data of the target user when using the screen is within a preset comfort range.

[0080] Specifically, because the user needs to use their eyes to see when using the screen, the eye feature data will change due to the influence of screen brightness, color temperature, and the light inside the car. Whether the user is in a comfortable state when using the screen can be determined by obtaining the user's eye feature data such as pupil diameter, blinking frequency, etc., and judging whether these eye feature data are within the preset comfort range, thereby determining whether the user's eyes are in a comfortable state when currently using the screen.

[0081] The preset comfort interval of the user and the user identity and other information can be stored in association by pre-building a database. In this way, when the user uses the screen, the user identity and other information can be identified by the camera combined with visual recognition technology, and then the preset comfort interval corresponding to the target user can be extracted from the database. For example, the preset comfort interval extracted from the database includes: the pupil diameter range is d1-d2 mm, the blink frequency range is 0-f1, where the blink frequency can be the number of blinks per unit time, such as the number of blinks in 10 seconds, and the target user can be the user who is using the screen in the vehicle, and the screen here can be the central control screen on the vehicle, the screen behind the seat, etc.

[0082] It is understandable that those skilled in the art may also use other methods to select or search for the preset comfort range, which is not limited here.

[0083] 402. If not, determine the comfort parameter to be adjusted according to the comparison result between the eye feature data and the endpoint value of the preset comfort range.

[0084] Specifically, when it is determined that the eye feature data is within a preset comfort range, the comfort parameters may be kept unchanged. The comfort parameters here include in-vehicle light parameters and screen display parameters such as screen brightness, screen color temperature, etc.

[0085] When it is determined that the eye feature data is not within the preset comfort range, the eye feature data can be compared with the endpoint value of the preset comfort range to determine the state of the target user's eyes at this time, and then determine the comfort parameters that need to be adjusted.

[0086] The pupil diameter changes accordingly due to the amount of light entering, and the blinking frequency is directly related to eye fatigue. The comfort parameter associated with the pupil diameter is the in-car light parameter, and the comfort parameter associated with the blinking frequency is the screen display parameter. The relevant comfort parameters are determined based on the degree of deviation between the eye feature data and the corresponding comfort interval.

[0087] For example, when the pupil diameter of the target user is smaller than d1 and the blinking frequency is smaller than f1, it means that the light inside the car is dim but the eyes are not tired. At this time, the corresponding comfort parameter that needs to be adjusted is the light parameter inside the car.

[0088] When the pupil diameter of the target user is greater than d2 and the blinking frequency is less than f1, it means that the light inside the car is bright, but the eyes are not tired. At this time, the corresponding comfort parameter that needs to be adjusted is the light parameter inside the car.

[0089] When the pupil diameter of the target user is smaller than d1 and the blinking frequency is greater than f1, it means that the light inside the car is dim and the eyes are tired. At this time, the corresponding comfort parameters that need to be adjusted are the light parameters inside the car and the screen display parameters.

[0090] When the pupil diameter of the target user is greater than d1 and the blinking frequency is greater than f1, it means that the light inside the car is too bright and the eyes are tired. At this time, the corresponding comfort parameters that need to be adjusted are the light parameters inside the car and the screen display parameters.

[0091] 403. Adjust the comfort parameters according to the preset comfort range to restore the eye feature data to the preset comfort range, where the comfort parameters include: in-vehicle light parameters and / or screen display parameters.

[0092] Specifically, based on determining the comfort parameter that needs to be adjusted, the comfort parameter is adjusted with a preset comfort range as the target, and at the same time, the user's eye feature data is monitored in real time. The adjustment of the comfort parameter can be stopped when it is adjusted to within the preset comfort range.

[0093] For example, as described above, the sunshade and lights in the vehicle can be controlled to increase the brightness in the vehicle, thereby restoring the pupil diameter of the target user to a preset comfort range. When adjusting the sunshade and lights, the lights and sunshade in the corresponding area can be adjusted according to the position of the screen, which will not be described in detail here.

[0094] From the above, it can be seen that the user vision protection method of the present application can personalize the in-car lighting, screen brightness and color temperature according to the user's eye feature data to meet the experience needs of different users, ensure the user's visual comfort when viewing the screen, and effectively protect the user's vision.

[0095] In a possible implementation, in order to effectively protect the user's vision when the user screen is used, not limited to visual protection for users with identity permissions, the process of determining the preset comfort interval may specifically include:

[0096] Step 11: Obtain physiological characteristic data of the target user;

[0097] Step 12: determining a preset comfort range based on the physiological characteristic data, where the physiological characteristic data includes: the target user's gender, age, and a wearing mark indicating whether the user wears glasses.

[0098] Specifically, image recognition technology can be used. When it is detected that a user is using the screen, for example, when the user's eyes stay on the screen for longer than a preset value, or when it is detected that the screen is touched, the image recognition technology is activated to recognize the captured facial image of the user, and then determine the user's gender, age, and whether he wears glasses, and then find the corresponding preset comfort range from the database based on these physiological characteristic data.

[0099] It should be noted that those skilled in the art may use well-known image recognition technology to acquire the above-mentioned physiological characteristic data, which will not be elaborated here.

[0100] In a possible implementation, considering that when there are multiple people in front of the screen, the visual sense of the user who really needs protection may be uncomfortable, in order to further improve the user experience, the process of determining the target user may specifically include:

[0101] Step 21: If only one user is currently using the screen, the user is determined as a target user;

[0102] Step 22: If multiple users are currently using the screen, a user with the highest priority is determined based on the identity information of each user, and the user with the highest priority is used as the target user.

[0103] Specifically, when it is identified that only one user is using the screen, a corresponding preset comfort range may be searched based on the user's physiological characteristic data.

[0104] When it is found that multiple people are using the screen at that time, if it is determined according to the identity information of each user that the users include a driver, the driver is taken as the target user;

[0105] If the users do not include the driver but include children, the children are taken as target users. When the number of children is not less than two, the child closest to the screen is taken as the target user.

[0106] If the users do not include the driver and the child, the user closest to the screen is taken as the target user.

[0107] It is understandable that those skilled in the art may adjust the process of determining the target user in the above multi-user scenario as needed, and no limitation is made here.

[0108] In a possible implementation, in order to meet the personalized needs of users, the user vision protection method may also include the following processing:

[0109] Step 31, obtaining the current eye feature data of the target user according to the in-car light parameters and / or screen display parameters adjusted by the target user;

[0110] Step 32: Update and adjust the preset comfort range according to the current eye feature data.

[0111] Specifically, after the user manually adjusts the in-car shading, screen brightness, and color mode, the comfort parameters after the user's adjustment are taken as the basis, the adjusted pupil diameter and blinking frequency are collected, compared with the original comfort range, the user's comfort range is adjusted, and the user's pupil diameter and blinking frequency comfort range are iteratively updated.

[0112] As a feasible implementation of step 401, the eye feature data includes: pupil diameter and blinking frequency, and the preset comfort intervals include: pupil comfort intervals and blinking comfort intervals. Determining whether the eye feature data of the target user when using the screen is within the preset comfort interval may specifically include:

[0113] If the pupil diameter is within the pupil comfort range and the blinking frequency is within the blinking comfort range, it is determined that the eye feature data is within the preset comfort range;

[0114] If the pupil diameter is not within the pupil comfort range and / or the blinking frequency is not within the blinking comfort range, it is determined that the eye feature data is not within the preset comfort range.

[0115] Specifically, only when the pupil diameter and the blinking frequency are both within the corresponding comfort range, the user's eyes are determined to be comfortable within the comfort range, and there is no need to adjust the comfort parameters. On the contrary, as long as one of the items is not within the corresponding comfort range, the eyes can be determined to be in an uncomfortable state.

[0116] When specifically determining the state of discomfort, the first state result data representing whether the eyes are in fatigue and the second state result data representing the brightness of the light in the vehicle can be determined based on the first comparison result between the pupil diameter and the two endpoint values ​​of the pupil comfort interval and the second comparison result between the blinking frequency and the maximum endpoint value of the blinking comfort interval. The comfort parameter can then be determined based on the first state result data and the second state result data.

[0117] Specifically, the two endpoint values ​​of the pupil comfort interval, namely the maximum value and the minimum value, can be used for judgment. As for the blink comfort interval, since its minimum value is generally 0, only the maximum value of the blink comfort interval can be used for judgment.

[0118] For example, when the pupil diameter is smaller than the minimum value of the pupil comfort range and the blinking frequency is lower than the maximum value of the blinking comfort range, it means that the ambient light is dim but the eyes are not tired. The comfort parameters that need to be adjusted are: the in-car light parameters.

[0119] If the pupil diameter is within the pupil comfort range and the blinking frequency is higher than the maximum value of the blinking comfort range, it means that the ambient light brightness is appropriate, but the eyes are tired. The comfort parameters that need to be adjusted are: screen display parameters, such as screen brightness and color temperature.

[0120] By analogy, for combinations of other comfort ranges, the comfort parameters that need to be adjusted are: interior lighting parameters and screen display parameters, that is, both the interior lighting parameters and the screen display parameters need to be adjusted.

[0121] On this basis, as an implementation method of the above step 403, adjusting the comfort parameter according to the preset comfort range so as to restore the eye feature data to the preset comfort range may specifically include:

[0122] Step 41, determining the numerical adjustment direction of the in-vehicle light parameter and / or the screen display parameter according to the first state result data and the second state result data;

[0123] Step 42: adjust the values ​​of the in-vehicle light parameters and / or screen display parameters according to the data adjustment direction.

[0124] Specifically, the comfort parameters that need to be adjusted in the above various uncomfortable states are taken as an example:

[0125] When the pupil diameter is smaller than the minimum value of the pupil comfort range and the blinking frequency is lower than the maximum value of the blinking comfort range, it means that the ambient light is dim but the eyes are not tired, then increase the lighting parameters in the car.

[0126] If the pupil diameter is within the pupil comfort range and the blinking frequency is higher than the maximum value of the blinking comfort range, it means that the ambient light brightness is appropriate, but the eyes are tired. In this case, increase the screen display parameters, such as screen brightness and color temperature.

[0127] When the pupil diameter is smaller than the minimum value of the pupil comfort range and the blinking frequency is greater than the maximum value of the blinking comfort range, it means that the ambient light is dim and the eyes are in a state of fatigue, and it is necessary to coordinately increase the interior lighting and screen brightness and color temperature.

[0128] When the pupil diameter is larger than the maximum value of the pupil comfort range and the blinking frequency is lower than the maximum value of the blinking comfort range, it means that the ambient light is bright but the eyes are not tired. In this case, you should lower the interior lights, increase glass shading, lower the screen brightness, etc.

[0129] When the pupil diameter is larger than the maximum value of the pupil comfort range, and the blinking frequency is larger than the maximum value of the blinking comfort range, it means that the ambient light is bright but the eyes are tired. In this case, you need to lower the lights in the car, increase glass shading, and maintain or increase the screen brightness and color temperature.

[0130] In the specific implementation, in order to facilitate the adjustment of comfort parameters, the visual sensitivity model can be used, with the preset comfort range as the target, and the current pupil diameter and blinking frequency can be input to determine the corresponding change direction of the pupil diameter and blinking frequency (increase or decrease), and then the corresponding lighting, sunshade, and screen display parameters can be adjusted.
