[0027] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0028] A method and device for adjusting a cabin entertainment screen according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0029] As mentioned above, with the rapid increase in smart cockpits and users' demand for in-car entertainment, in-car entertainment screens are widely used in most car models, and the installation rate continues to rise. In-car entertainment screens can be widely used in various leisure and entertainment scenarios. For example, camping and watching movies in the car is a charming leisure method and is becoming a new trend for users to pursue nature and enjoy entertainment.

[0030] However, when camping outdoors at night, the environment outside the car is dark. When watching movies in the car, the in-car entertainment screen becomes the only strong light source, which forms a strong contrast with the surrounding environment. If the eyes are in this state of great contrast between light and dark for a long time, it will increase the burden of eye adjustment. In order to adapt to this brightness difference, the eyes need to constantly adjust the size of the pupil and the curvature of the lens, which can easily lead to eye fatigue. If this continues for a long time, it may cause vision problems such as myopia, especially for children and teenagers, whose eyes are in the development stage, and this poor eye environment is more likely to cause damage to vision.

[0031] In view of this, an embodiment of the present application provides a method for adjusting a cockpit entertainment screen, wherein ambient light information around the entertainment screen is collected by N ambient light sensors respectively, and when the collected ambient light information meets the fill light condition, an adjustable light group is called to fill light the ambient light, and the first ambient light brightness after fill light is further obtained by a vehicle-mounted camera device, and the display brightness of the entertainment screen is adjusted by using the brightness difference between the entertainment screen brightness and the first ambient light brightness after fill light, which can reduce the difference between the entertainment screen brightness and the ambient brightness, improve the accuracy of the entertainment screen display brightness adjustment, and enhance the user experience.

[0032] Figure 1 FIG. 1 is a flow chart of a cockpit entertainment screen adjustment method provided in an embodiment of the present application. Figure 1 As shown, the cockpit entertainment screen adjustment method includes the following steps:

[0033] In step S101 , ambient light information collected by N ambient light sensors is obtained.

[0034] Among them, N ambient light sensors are arranged around the cockpit entertainment screen, and N is a positive integer.

[0035] In step S102, in response to determining that each ambient light information satisfies the fill light condition, the adjustable light group is called to fill light the ambient light.

[0036] In step S103, a real-time image including at least the entertainment screen captured by the vehicle-mounted camera device is acquired, and the brightness of the first ambient light is determined according to the real-time image.

[0037] In step S104, a first brightness difference between the brightness of the entertainment screen and the brightness of the first ambient light is determined, and the display brightness of the entertainment screen is adjusted based on the first brightness difference.

[0038] In some embodiments of the present application, the method may be executed by a cockpit domain controller of the vehicle. The cockpit domain controller is connected to the cockpit entertainment screen and to various sensor devices and camera devices. The cockpit domain controller obtains the information collected by the sensor device and the camera device, and first adjusts the ambient light brightness of the cockpit entertainment screen according to the acquired information, and then accurately adjusts the display brightness of the entertainment screen according to the difference between the adjusted ambient light brightness and the brightness of the entertainment screen.

[0039] In some embodiments, the cockpit domain controller can obtain ambient light information collected by N ambient light sensors. The N ambient light sensors can be arranged around the cockpit entertainment screen. In one example, an ambient light sensor can be arranged on the front windshield, the rear windshield, the left window and the right window in the vehicle to capture the ambient brightness inside and outside the vehicle in all directions.

[0040] Furthermore, the cockpit domain controller can determine whether the ambient light information collected by the N ambient light sensors meets the fill light condition. If so, the adjustable light group is called to fill the ambient light to obtain the ambient light brightness after the fill light is applied. The specific implementation method of determining whether each ambient light information meets the fill light condition and the specific implementation method of calling the adjustable light group to fill the ambient light are described in detail below and will not be repeated here.

[0041] On the other hand, the cockpit domain controller can also obtain a real-time image taken by the vehicle-mounted camera device, including at least the entertainment screen, and determine the first ambient light brightness based on the real-time image, and the first ambient light brightness is the ambient light brightness after fill light. In one example, the first ambient light brightness can be determined by detecting the brightness value of each pixel in the real-time image. Alternatively, other image detection algorithms can be called to determine the first ambient light brightness, which is not limited here.

[0042] After determining the first ambient light brightness, a first brightness difference between the entertainment screen brightness and the first ambient light brightness can be determined, and finally the display brightness of the entertainment screen can be adjusted based on the first brightness difference. For example, if the ambient light brightness value after fill light is larger, the entertainment screen brightness can be increased by the first brightness difference so that the entertainment screen brightness is consistent with the ambient light brightness, thereby improving the user's viewing experience. Alternatively, if the ambient light brightness value after fill light is smaller, the entertainment screen brightness can be lowered by the first brightness difference so that the entertainment screen brightness is consistent with the ambient light brightness, thereby improving the user's viewing experience.

[0043] Among them, the brightness of the entertainment screen can be obtained by the cockpit domain controller directly from the entertainment screen or the entertainment screen control application.

[0044] According to the technical solution provided in the embodiment of the present application, ambient light information around the entertainment screen is collected respectively by N ambient light sensors, and when the collected ambient light information meets the fill light condition, the adjustable light group is called to fill light the ambient light, and the first ambient light brightness after the fill light is further obtained by the vehicle-mounted camera device. The brightness difference between the entertainment screen brightness and the first ambient light brightness after the fill light is used to adjust the display brightness of the entertainment screen, which can reduce the difference between the brightness of the entertainment screen and the ambient brightness, improve the accuracy of the entertainment screen display brightness adjustment, and enhance the user experience.

[0045] In some embodiments of the present application, the fill light condition may include at least one of the following: the variance of each ambient light information is greater than a preset variance threshold; the variance of each ambient light information is less than or equal to the preset variance threshold, and the second ambient light brightness determined based on each ambient light information is less than a preset brightness threshold.

[0046] Among them, the environment of the cockpit entertainment screen can be divided into a daytime environment and a night environment. Whether the current environment is a daytime environment or a nighttime environment can be determined by judging the relationship between the ambient light brightness and the preset brightness threshold. For example, if the second ambient light brightness determined based on the collected N ambient light information is greater than or equal to the preset brightness threshold, it can be determined that the current environment is a daytime environment. Conversely, if the second ambient light brightness determined based on the collected N ambient light information is less than the preset brightness threshold, it can be determined that the current environment is a nighttime environment. Furthermore, the second ambient light brightness can be obtained by weighted averaging the ambient light brightness in the N ambient light information, and the weight of each ambient light information can be set according to factors such as the setting position and sensitivity of the sensor, which is not limited here.

[0047] It can be understood that the specific values ​​of the above-mentioned preset variance threshold and the preset brightness threshold can be determined according to actual needs and are not limited here.

[0048] Figure 2 FIG. 1 is a flow chart of a method for calling an adjustable light group to supplement ambient light provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0049] In step S201, in response to determining that the variance of each ambient light information is less than or equal to a preset variance threshold, and the second ambient light brightness is less than a preset brightness threshold, the adjustable light group is called to fill the ambient light to the preset ambient light brightness.

[0050] In step S202 , in response to determining that the variance of each ambient light information is greater than a preset variance threshold, it is determined that the ambient light sensor is blocked.

[0051] In step S203, the adjustable light group is called to fill the area where the ambient light sensor is blocked to a first target ambient light brightness.

[0052] The blocked ambient light sensor is an ambient light sensor whose difference between the collected ambient light information and the mean of each ambient light information is greater than a first preset threshold, and the first target ambient light brightness is an ambient light brightness determined based on the ambient light information collected by the other ambient light sensors except the blocked ambient light sensor. Furthermore, the first preset threshold is a negative number.

[0053] In some embodiments of the present application, if each ambient light information satisfies the fill light condition, that is, the variance of each ambient light information is less than or equal to the preset variance threshold, and the second ambient light brightness determined according to each ambient information is less than the preset brightness threshold, the adjustable light group can be directly called to fill the ambient light to the preset ambient light brightness. Among them, the preset ambient light brightness can be a preset brightness value, or a brightness value in a preset brightness value set. If the preset ambient light brightness is a preset brightness value, the brightness value can be set to a value greater than the above-mentioned preset brightness threshold. If the preset ambient light brightness is a brightness value in a preset brightness value set, the most suitable brightness value can be determined in the preset brightness value set as the preset ambient light brightness through information such as the current time and the current scene.

[0054] In other embodiments of the present application, if each ambient light information satisfies the fill light condition, that is, the variance of each ambient light information is greater than a preset variance threshold, then the blocked ambient light sensor can be determined first, and then the adjustable light group is called to fill light the area where the blocked ambient light sensor is located to the first target ambient light brightness. The blocked ambient light sensor can be determined by screening the brightness value of which is significantly lower than the first ambient light brightness determined according to each ambient light information.

[0055] That is to say, the second ambient light brightness can be first determined according to the average value of each ambient light brightness corresponding to each ambient light information. Then, the ambient light sensor whose difference between the ambient light brightness and the second ambient light brightness is greater than the preset first preset threshold is determined as the occlusion light sensor. The specific value of the first preset threshold can be determined according to actual needs and is not limited here.

[0056] Furthermore, the adjustable light group can be called to fill the area where the ambient light sensor is blocked to the first target ambient light brightness. At this time, the target ambient light brightness can be the ambient light brightness determined based on the ambient light information collected by other ambient light sensors except the blocked ambient light sensor.

[0057] Figure 3 : is a flow chart of another cockpit entertainment screen adjustment method provided in an embodiment of the present application. Figure 3 Step S301 in the illustrated embodiment is Figure 1 Step S101 in the illustrated embodiment is substantially the same and will not be described in detail herein. Figure 3 As shown, the cockpit entertainment screen adjustment method also includes the following steps:

[0058] In step S302, in response to determining that each piece of ambient light information does not satisfy the fill light condition, a second ambient light brightness is determined according to the N pieces of ambient light information.

[0059] In step S303, a second brightness difference between the brightness of the entertainment screen and the brightness of the second ambient light is determined, and the display brightness of the entertainment screen is adjusted based on the second brightness difference.

[0060] In some embodiments of the present application, if the cockpit domain controller determines that each ambient light information does not meet the fill light condition, the second ambient light brightness is determined according to the N ambient light information. Determining the second ambient light brightness according to the N ambient light information may be to obtain the ambient light brightness corresponding to each ambient light information, average the N ambient light brightnesses, and obtain the second ambient light brightness.

[0061] At this time, since there is no need to perform fill light operation, the data collected by the ambient light sensor is more reliable, so the second brightness difference between the brightness of the entertainment screen and the second ambient light brightness can be directly determined, and the display brightness of the entertainment screen can be adjusted based on the second brightness difference.

[0062] By adopting the technical solution of the embodiment of the present application, it is first determined whether fill light is needed based on the ambient light information collected by the ambient light sensor, and then the brightness of the ambient light after fill light or the second ambient light brightness when fill light is not needed is compared with the brightness of the entertainment screen to obtain the brightness difference. Finally, the display brightness of the entertainment screen is adjusted based on the brightness difference. This can reasonably compensate for the ambient light of the cabin entertainment screen in application scenarios such as camping and watching movies in the car, and accurately adjust the display brightness of the entertainment screen to match the ambient light brightness, thereby improving the user experience.

[0063] Figure 4 : is a flowchart of another cockpit entertainment screen adjustment method provided in an embodiment of the present application. Figure 4 Steps S401 to S402 in the embodiment shown are Figure 1 Steps S101 to S102 in the illustrated embodiment are substantially the same and will not be described in detail herein. Figure 4 As shown, the cockpit entertainment screen adjustment method also includes the following steps:

[0064] In step S403, in response to determining that the difference between the first ambient light brightness and the entertainment screen brightness is greater than the second preset threshold, the adjustable light group is called to fill the ambient light again to obtain a third ambient light brightness.

[0065] The third ambient light brightness is the ambient light brightness after the second fill light.

[0066] In step S404, a third brightness difference between the brightness of the entertainment screen and the brightness of the third ambient light is determined, and the display brightness of the entertainment screen is adjusted based on the third brightness difference.

[0067] In some embodiments of the present application, after calling the adjustable light group to fill in the ambient light, the second ambient light brightness collected by the vehicle-mounted camera device can also be compared with the entertainment screen brightness. If the difference between the two is greater than the second preset threshold, it means that there is still a large difference between the current ambient light brightness after fill-in and the entertainment screen brightness. At this time, the adjustable light group can be called to fill in the ambient light again to obtain a third ambient light brightness. The operation method for fill-in again is basically the same as the operation method for the first fill-in mentioned above, and will not be repeated here. Among them, the specific value of the second preset threshold can be determined according to actual needs, and there is no limitation here.

[0068] After completing the second fill light, the cockpit domain controller can determine a third brightness difference between the brightness of the entertainment screen and the brightness of the third ambient light, and then adjust the display brightness of the entertainment screen based on the third brightness difference.

[0069] By adopting the technical solution of the embodiment of the present application, after the ambient light is initially supplemented using the information collected by the ambient light sensor, it is also possible to determine whether the ambient light needs to be supplemented again based on the real-time image obtained by the on-board camera device, thereby further improving the accuracy of compensating for the ambient light of the cabin entertainment screen, and improving the adjustment accuracy of adjusting the display brightness of the entertainment screen to match the ambient light brightness, thereby improving the user experience.

[0070] In some embodiments of the present application, the adjustable light group may include a warm-colored light group and a cold-colored light group. Furthermore, calling the adjustable light group to fill in the ambient light may be to obtain target ambient light information, and determine the target light group in the adjustable light group and the target brightness of the target light group according to the second target ambient light brightness and the target ambient light color temperature included in the target ambient light information. The target light group is controlled to work at the target brightness to fill in the ambient light. Among them, the target ambient light information can be determined by querying the ambient light information matching the N collected ambient light information in the preset mapping relationship table, or it can be determined based on the N collected ambient light information, entertainment screen light information, and user eye-related information. User eye-related information may include, for example, the user's eye use time, the user's eye fatigue, the user's viewing angle of the entertainment screen, etc.

[0071] That is to say, the adjustable light group may include a warm light group and a cool light group. The other warm light groups and cool light groups may be independent light groups or light groups composed of adjustable light groups. Each light group includes at least one lamp. When calling the adjustable light group to fill in the ambient light, in addition to obtaining the target ambient light brightness to be filled in, the target ambient light color temperature may also be obtained, and which light groups to call for fill in may be determined according to the target ambient light color temperature.

[0072] Figure 5 : is a flowchart of another cockpit entertainment screen adjustment method provided in an embodiment of the present application. Figure 5Steps S501 to S504 in the embodiment shown are Figure 1 Steps S101 to S104 in the illustrated embodiment are substantially the same and will not be described in detail herein. Figure 5 As shown, the cockpit entertainment screen adjustment method also includes the following steps:

[0073] In step S505, an infrared detection device is called to detect the status of passengers in the vehicle.

[0074] In step S506, in response to determining that there are no passengers in the car, or determining that the time for which the passengers in the car have not watched the entertainment screen is greater than or equal to the first preset time, the entertainment screen program is paused.

[0075] In step S507, in response to determining that the time duration for which the in-vehicle passenger is in the state of watching the entertainment screen is greater than or equal to a second preset time duration, the fatigue state of the in-vehicle passenger is detected.

[0076] In step S508, in response to determining that the in-vehicle passenger is fatigued, a rest reminder is displayed on the entertainment screen.

[0077] In some implementations, after adjusting the display brightness of the entertainment screen, the cockpit domain controller may call an infrared detection device to detect the status of passengers in the vehicle and time the detection duration.

[0078] If the infrared detection device determines that there are no passengers in the car, or determines that the time for which the passengers in the car have not watched the entertainment screen is greater than or equal to the first preset time, the cockpit domain controller pauses playing the entertainment screen program.

[0079] On the other hand, the infrared detection device can also detect the fatigue state of the passengers in the car when the timing duration is greater than or equal to the second duration. This is because the human eyes will show different physiological characteristics in different states. When a person is in a state of fatigue, the blood circulation around the eyes will change, and the tension of the eye muscles will also be different. In addition, the frequency of blinking, the degree of opening and closing of the eyes, etc. of a person in a fatigued state will also change. The infrared sensor uses the characteristics of infrared rays to detect these changes. Infrared rays have a certain penetrating ability and can penetrate a certain depth of human tissue. When infrared rays are irradiated to the eyes, part of the infrared rays will be reflected back by the eye tissue. The reflection characteristics of infrared rays by eye tissue in different states are different. For example, the increase in blood flow around the eyes in a fatigued state will cause the reflection intensity of infrared rays to change. If the fatigue of the passengers in the car is determined by the infrared detection device, a rest reminder can be displayed on the entertainment screen.

[0080] Figure 6 Schematic diagram of the structure of a cockpit entertainment screen adjustment system provided in an embodiment of the present application. Figure 6As shown, the system includes a cockpit domain controller, an ambient light sensor, a camera, an infrared sensor, an in-vehicle adjustable light group and an entertainment screen. The cockpit domain controller receives information collected by the ambient light sensor, the camera and the infrared sensor respectively, processes the information, and controls the action of the in-vehicle adjustable light group and the entertainment screen according to the processing results, including adjusting the display brightness of the entertainment screen, controlling the entertainment screen to play or pause programs, and controlling the entertainment screen to display prompt information.

[0081] Figure 7 FIG. 1 is a flow chart of another method for adjusting the cockpit entertainment screen provided in an embodiment of the present application. Figure 7 As shown, after starting the in-car entertainment screen, the cockpit domain controller can input the data collected by the ambient light sensor and control the entertainment screen to run with default parameters. Subsequently, the cockpit domain controller determines the data variance of multiple ambient light sensors. If the variance is large, that is, the brightness values ​​in the data collected by each ambient light sensor are greatly different and are not near the average brightness, the adjustable light group can be called to adjust the ambient light, and then the camera data of the vehicle-mounted camera device, that is, the real-time image, is obtained, and the ambient light brightness is determined based on the real-time image, and then the determined ambient light brightness is compared with the entertainment screen display brightness, and the entertainment screen display brightness is adjusted according to the comparison result.

[0082] On the other hand, if the data variances of multiple ambient light sensors are small and are all near the mean, the ambient mode is further judged. If the variance of each current ambient light information is less than or equal to the preset variance threshold, and the second ambient light brightness determined based on each ambient information is less than the preset brightness threshold, the universal can call the adjustable light group to adjust the ambient light, and then obtain the camera data of the vehicle-mounted camera device, that is, the real-time image, determine the ambient light brightness based on the real-time image, and then compare the determined ambient light brightness with the entertainment screen display brightness, and adjust the entertainment screen display brightness based on the comparison result.

[0083] On the contrary, if it is a daytime environment, the ambient light information collected by the ambient light sensor can be used to directly adjust the display brightness of the entertainment screen.

[0084] After the entertainment screen has finished adjusting the brightness and started working, a timer can be started and the infrared detection device can be called for detection. If the detection finds that there are no passengers in the car, the entertainment screen program can be paused and the infrared detection can be continued. If the detection is carried out for a period of time, such as 20 minutes after it is still determined that there are no passengers in the car, the entertainment system can be turned off.

[0085] On the other hand, if the infrared detection determines that there are passengers in the car, the infrared sensor can be used to further detect whether the viewer watching the entertainment screen is tired at a preset period. If it is determined that the viewer is not tired, no additional operation is performed. On the contrary, if it is determined that the viewer is tired, a prompt message can be displayed on the entertainment screen to prompt the viewer to take a rest.

[0086] That is to say, the technical solution provided in the embodiment of the present application adjusts parameters such as the brightness of the in-vehicle lighting and entertainment screen through intelligent detection and adjustment methods to improve the comfort of watching movies in the car and reduce damage to the human eye caused by the incoordination between the brightness of the entertainment screen and the ambient light.

[0087] In one example, ambient light sensors can be placed on the front windshield, rear windshield, left and right windows, and a camera can be placed on the roof at the center of the rear row. The camera on the roof at the center of the rear row can capture the in-car entertainment screen and the surrounding in-car environment. This arrangement can accurately capture the ambient brightness inside and outside the car, providing data support for subsequent brightness adjustment. An infrared sensor is placed near the rear entertainment screen to detect whether there are viewers and monitor whether the viewers are experiencing visual fatigue.

[0088] Furthermore, a yellow, warm white, color-changing and brightness-adjustable lamp group can be arranged at a suitable position of the vehicle. This lamp group can automatically adjust the brightness according to the change of ambient brightness, thereby improving the comfort of human eyes.

[0089] The cockpit domain controller receives the signal from the ambient light sensor and determines whether to turn on the lighting of the viewing environment compensation lighting group. This control method can accurately determine the contrast between the screen brightness and the ambient brightness, avoiding eye fatigue and vision damage.

[0090] Furthermore, a camera is placed on the roof at the center of the rear row to capture the image information of the screen and the environment, and the contrast between the screen brightness and the ambient brightness is judged again through the image information. This judgment method can adjust the screen brightness more accurately and improve the viewing experience. At the same time, the screen brightness is automatically adjusted according to different ambient light changes. This adjustment method can improve the comfort of the human eye and avoid eye fatigue and vision damage.

[0091] In addition, after adjusting the brightness of the rear entertainment screen and the cabin ambient light, infrared sensors can be used to continuously detect whether there are viewers and monitor their visual fatigue.

[0092] By adopting the technical solution of the embodiment of the present application, the ambient light intensity is determined by an ambient light sensor, and a color-changing and dimmable ambient compensation lighting group independent of the traditional reading light is added to the vehicle. The background light of the ambient compensation lighting group is used to reduce the brightness contrast between the TV screen and the surrounding environment, thereby reducing the adjustment burden on the eyes. After taking a photo with the camera, the controller determines the ambient light and screen brightness, and automatically adjusts the screen and the ambient compensation lighting group. The camera has a large lighting range, which reduces the misjudgment and misadjustment of a single ambient light sensor under conditions such as direct sunlight and shadows. Automatic adjustment is adopted to reduce the operating burden on drivers and passengers.

[0093] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0094] The following are device embodiments of the present application, which can be used to execute the method embodiments of the present application. For details not disclosed in the device embodiments of the present application, please refer to the method embodiments of the present application.

[0095] Figure 8 Schematic diagram of a cockpit entertainment screen adjustment device provided in an embodiment of the present application. Figure 8 As shown, the device comprises:

[0096] The acquisition module 801 is configured to acquire ambient light information collected by N ambient light sensors respectively, where the N ambient light sensors are arranged around the cockpit entertainment screen, and N is a positive integer.

[0097] The fill light module 802 is configured to call the adjustable light group to fill light the ambient light in response to determining that each ambient light information meets the fill light condition.

[0098] The determination module 803 is configured to obtain a real-time image including at least the entertainment screen taken by the vehicle-mounted camera device, and determine the first ambient light brightness according to the real-time image.
