Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for adjusting screen brightness according to an embodiment of the present invention, where the method may include the following steps:
s101: the current ambient light illuminance of the vehicle is acquired.
S102: and if the current illumination of the ambient light is less than the first illumination threshold, adjusting the brightness of a light source in the vehicle based on the current illumination of the ambient light and the reflection coefficient of a screen in the vehicle, so that the adjusted brightness of the screen reaches a preset brightness threshold.
Wherein the light source in the vehicle is a backlight of the screen and/or a supplemental light source for adjusting the ambient light around the screen.
S103: and if the current illumination of the ambient light is greater than the second illumination threshold, calculating the concentration of the water mist needing to be sprayed currently according to the current illumination of the ambient light and the refractive index of the screen to be used as the target concentration.
Wherein the second illumination threshold is greater than the first illumination threshold.
S104: water mist of a target concentration is sprayed in a designated area between the eyes of the user and the screen to reduce the brightness of the screen.
Based on the screen brightness adjusting method provided by the embodiment of the present invention, when the current illuminance of the ambient light is smaller than the first illuminance threshold, it indicates that the current illuminance of the ambient light on the screen in the vehicle is low, and the brightness of the screen is also low, so that the user may not view the content displayed in the screen. Therefore, the brightness of the light source can be adjusted based on the current illuminance of the ambient light and the reflection coefficient of the screen, so that the adjusted brightness of the screen reaches the preset brightness threshold, and the brightness of the screen can be increased, so that the user can view the content displayed in the screen. When the current illuminance of the ambient light is greater than the second illuminance threshold, it indicates that the current illuminance of the ambient light on the screen in the vehicle is higher, and the brightness of the screen is also higher, so that the user may not view the content displayed on the screen. Therefore, the target concentration of the water mist required to be sprayed at present is calculated according to the current illuminance of the ambient light and the refractive index of the screen, the water mist with the target concentration is sprayed in the designated area between the eyes of the user and the screen, and the water mist can be formed in front of the screen, so that the reflection coefficient of the screen is changed, further, the brightness of the screen can be reduced, and the user can watch the content displayed in the screen. In summary, the screen brightness adjusting method provided by the embodiment of the invention can adjust the brightness of the screen in a self-adaptive manner, and is convenient for a user to watch the content displayed in the screen.
In step S101, the screen brightness adjusting method provided by the embodiment of the present invention can be applied to a host in a brightness adjusting system. The host may be an in-vehicle electronic device, or an edge server, or a cloud server, but is not limited thereto.
When the host is an in-vehicle electronic device, the host may be disposed inside the vehicle. The Vehicle-mounted Electronic device is any Vehicle-mounted information interaction terminal such as a central computer, or a central domain controller, or an integrated Electronic Control Unit (ECU), or a driver's brain, or a Vehicle machine, a DHU (driving Head Unit, an integrated machine of an entertainment host and a meter), an IHU (information Head Unit), an In-Vehicle Infotainment, an IVI (In-Vehicle Infotainment), and the like.
The brightness adjustment system may further include an illumination sensor for detecting the current illuminance of the ambient light of the vehicle, that is, the current illuminance of the ambient light of the screen in the vehicle. The illumination sensor may be in communication with a host.
In one implementation, the illumination sensor may be a solar-rain sensor disposed outside the vehicle, and the illumination sensor may detect an illumination of current ambient light (e.g., sunlight, light of a street lamp, etc.) outside the vehicle to obtain the illumination of the current ambient light of the vehicle.
In another implementation, the illumination sensor may also be disposed near the screen, and the illumination sensor may detect an illumination of ambient light inside the vehicle (e.g., sunlight irradiated to the inside of the vehicle, light of a reading lamp inside the vehicle, etc.), so as to obtain an illumination of the current ambient light of the vehicle.
Based on the above processing, the illuminance of the ambient light inside the vehicle can be detected by the illumination sensor disposed near the screen, as compared with the case where the sunlight and rainfall sensor can only detect the illuminance of the current ambient light outside the vehicle, and thus, the accuracy of the detected current ambient light on the screen can be improved.
In step S102, in one implementation, after acquiring the illuminance of the current ambient light of the vehicle, the host may directly determine whether the illuminance of the current ambient light is less than the first illuminance threshold. The first illuminance threshold may be set empirically by a skilled person, for example, the first illuminance threshold may be 10lx (lux), or the first illuminance threshold may be 15lx, but is not limited thereto.
In another implementation, before step S102, the method may further include the following steps:
the method comprises the following steps: and acquiring the time period of the current moment.
Step two: in the corresponding relation between the preset time period and the illumination threshold, determining the illumination threshold corresponding to the time period to which the current moment belongs as a first illumination threshold.
That is, a day may be divided into a plurality of time periods, and each time period may correspond to a different first illuminance threshold. For example, a day may be divided into a first time period and a second time period, the first time period may include a sunrise time period, the second time period may include a sunset time period, the illuminance threshold corresponding to the first time period is a first illuminance threshold, and the illuminance threshold corresponding to the second time period may be referred to as a third illuminance threshold.
For example, 6 am to 14 pm may be used as the first time period, and the first illuminance threshold corresponding to the first time period is 15lx to 20lx. And taking 14 pm to 6 am as a second time period, wherein a third illumination threshold corresponding to the second time period is 5lx to 10lx.
If the current time belongs to 6 am to 14 pm, the host computer may determine whether the current illuminance of the ambient light is less than a first illuminance threshold. If the current time belongs to 14 pm to 6 am, the host computer may determine whether the current illuminance of the ambient light is less than a third illuminance threshold.
In addition, in the case of extreme daytime or nighttime, one illumination threshold value (i.e., a first illumination threshold value) may be set for one day, and for example, the first illumination threshold value may be 5lx to 20lx. That is, the first illuminance threshold may be 5lx, or may also be 8lx, or may also be 10lx, or may also be 15lx, but is not limited thereto.
Furthermore, if the first day is divided into the first time zone and the second time zone, and if the illuminance of the current ambient light is smaller than the first illuminance threshold value when the current time belongs to the first time zone, it can be determined that the illuminance of the current ambient light on the screen in the vehicle is low, and the brightness of the screen is also low. If the current time belongs to the second time period, the illuminance of the current ambient light is less than the third illuminance threshold, and it may be determined that the illuminance of the current ambient light on the screen in the vehicle is low, and then the brightness of the screen is also low.
If the time periods are not divided, the host may determine that the illuminance of the current ambient light on the screen in the vehicle is low when determining that the illuminance of the current ambient light is smaller than the first illuminance threshold, and the brightness of the screen is also low, which may prevent the user from viewing the content displayed on the screen. Therefore, the host can supplement light to the screen through the light source in the vehicle to increase the brightness of the screen. That is, the host computer may adjust the brightness of the light source based on the current illuminance of the ambient light and the reflection coefficient of the screen, so that the adjusted brightness of the screen reaches the preset brightness threshold, and the brightness of the screen may be increased, so that the user may view the content displayed in the screen.
The preset luminance threshold may be set by a skilled person according to experience, for example, the preset luminance threshold may be any value in a preset luminance interval, the preset luminance interval includes luminances suitable for human eyes to watch, for example, the preset luminance interval may be [10cd/m ] 2 ，160cd/m 2 ]Then the preset luminance threshold may be 10cd/m 2 (candela per square meter), or the preset luminance threshold may be 20cd/m 2 But is not limited thereto.
In an embodiment of the present invention, on the basis of fig. 1, referring to fig. 2, step S102 may include the following steps:
s1021: and if the illumination of the current ambient light is smaller than the first illumination threshold value, calculating the product of the illumination of the current ambient light and the reflection coefficient of the screen in the vehicle to obtain the current brightness of the screen.
S1022: and calculating the difference value between the preset brightness threshold value and the current brightness of the screen to obtain the brightness which corresponds to the screen and needs to be supplemented currently.
S1023: and adjusting the light source in the vehicle to the brightness which needs to be supplemented currently so as to enable the brightness of the adjusted screen to reach a preset brightness threshold value.
If the host determines that the current illuminance of the ambient light is less than the first illuminance threshold, which indicates that the current illuminance of the ambient light on the screen in the vehicle is low, the brightness of the screen is also low, and the user may not be able to view the content displayed on the screen. Therefore, the host can determine the current brightness of the screen, and fill light for the screen through the light source according to the current brightness of the screen so as to increase the brightness of the screen.
In one implementation, the host may calculate a product of the reflection coefficient of the screen and the current illuminance of the ambient light to obtain the current brightness of the screen. And then, calculating a difference value between the preset brightness threshold value and the current brightness of the screen to obtain the current brightness needing to be supplemented, which corresponds to the screen. The reflection coefficient of the screen may be 1.5% to 1.7%.
Then, the host can adjust the light source to the brightness which needs to be supplemented currently, so that the adjusted brightness of the screen reaches the preset brightness threshold, and the user can observe the content displayed in the screen because the preset brightness threshold is the brightness suitable for the human eyes to watch.
In one implementation, the light source in the vehicle may be a backlight of the screen. The host can increase the voltage of the backlight lamp, so that the brightness of the backlight lamp is improved, and further, the contrast of the content displayed on the screen can be improved, so that a user can observe the content displayed on the screen.
In another implementation, the light source in the vehicle is a supplemental light source for adjusting the illuminance of ambient light around the screen. Accordingly, on the basis of fig. 2, referring to fig. 3, step S1023 may include the following steps:
s10231: and adjusting the supplementary light source to the brightness which needs to be supplemented currently so as to enable the adjusted brightness of the screen to reach a preset brightness threshold value.
The supplementary light source can be a reading lamp and an atmosphere lamp in the vehicle, or a supplementary light lamp installed near a screen.
In one embodiment of the present invention, step S10231 may include the following steps:
step 1, calculating the product of the brightness which is required to be supplemented currently and corresponds to the supplementary light source and the volume of the supplementary light source to obtain the luminous flux corresponding to the supplementary light source.
And 2, calculating the resistance value of the resistor of the supplementary light source according to the calculated luminous flux, the voltage of the supplementary light source and the luminous efficiency of the supplementary light source.
And 3, adjusting the resistance value of the resistor of the supplementary light source to the calculated resistance value so as to adjust the supplementary light source to the brightness which needs to be supplemented currently.
In one implementation, the host computer may calculate a product of the current brightness of the supplemental light source to be supplemented and the volume of the supplemental light source, so as to obtain the luminous flux corresponding to the supplemental light source. Then, the host computer can calculate the product of the square value of the voltage of the supplementary light source and the luminous efficiency of the supplementary light source, and calculate the quotient of the product and the luminous flux corresponding to the supplementary light source, so as to obtain the resistance value of the resistor of the supplementary light source. Because the resistor of the supplementary light source is an adjustable resistor, the host can adjust the resistance value of the resistor of the supplementary light source to the calculated resistance value, so that the current of the supplementary light source is changed, and the supplementary light source is adjusted to the brightness which needs to be supplemented currently.
In addition, if the light supplement requirement of the screen cannot be met by only adjusting the brightness of the supplement light source, that is, the maximum brightness of the supplement light source is less than the brightness which needs to be supplemented currently, the host can simultaneously adjust the brightness of the backlight and the brightness of the supplement light source, so as to increase the brightness of the screen.
In an embodiment of the present invention, after step S101, the method may further include the steps of: and under the condition that the illumination of the current ambient light is not less than the first illumination threshold value, if the light source in the current vehicle is in an open state, the light source in the vehicle is turned off.
In one implementation, after the illuminance of the current ambient light of the vehicle is obtained, if the illuminance of the current ambient light is not less than the first illuminance threshold, it is indicated that the current ambient light can make the brightness of the screen be the brightness suitable for the human eyes to watch, and a light source in the vehicle is not required to be used for light supplement. Therefore, if the light source in the vehicle is currently in the on state, the host machine may turn off the light source in the vehicle.
For step S103 and step S104, if the illuminance of the current ambient light is not less than the first illuminance threshold, the host may continue to determine whether the illuminance of the current ambient light is greater than the second illuminance threshold. The second illumination threshold may be a quotient of a maximum value of the preset luminance interval and a reflection coefficient of the screen.
If the current illumination of the ambient light is greater than the second illumination threshold, the brightness of the screen corresponding to the current illumination of the ambient light is greater than the maximum value of the preset brightness interval. The preset brightness interval comprises the brightness suitable for being watched by human eyes, and the brightness of the screen is larger than the maximum value of the preset brightness interval, so that the brightness of the screen is not suitable for being watched by a user. Therefore, the host can reduce the brightness of the screen.
In one implementation, the brightness adjustment system may further include a nebulizer in the vehicle. The host can control the atomizer to spray water mist with target concentration in a designated area between eyes of a user and the screen, and the water mist can be formed in front of the screen, so that the reflection coefficient of the screen is changed, and the brightness of the screen is reduced.
In an embodiment of the present invention, on the basis of fig. 1, referring to fig. 4, step S103 may include the following steps:
s1031: and if the current illumination of the ambient light is greater than the second illumination threshold value, calculating the refractive index which needs to be supplemented currently according to the current illumination of the ambient light and the refractive index of the screen.
S1032: and calculating the product of the refractive index required to be supplemented currently and a preset coefficient to obtain the concentration of the water mist required to be sprayed currently as a target concentration.
Referring to fig. 5, fig. 5 is a schematic diagram of light refraction according to an embodiment of the present invention. 501 denotes water mist in front of the screen, and 502 denotes the screen.
The reflection coefficient of the screen can be calculated according to the Fresnel law. Specifically, a difference (which may be referred to as a first difference) between the refractive index of the water mist and the refractive index of the screen, and a sum (which may be referred to as a first sum) between the refractive index of the water mist and the refractive index of the screen may be calculated. Further, a ratio of the square of the first difference to the square of the first sum (which may be referred to as a first ratio) may be calculated, the first ratio being a reflection coefficient of the screen.
Because the reflection coefficient of the screen is a known value, the refractive index of the water mist can be calculated according to the reflection coefficient of the screen. Specifically, a difference of 1 from the square root of the reflection coefficient of the screen (which may be referred to as a second difference) and a product of the second difference and the refractive index of the screen (which may be referred to as a first product) may be calculated, and a sum of 1 and the square root of the reflection coefficient of the screen (which may be referred to as a second sum) may be calculated. Further, a ratio of the first product to a second sum (which may be referred to as a second ratio) may be calculated, the second ratio being a refractive index of the mist.
Since the current brightness of the screen is the product of the reflection coefficient of the screen and the current illuminance of the ambient light. Therefore, the reflection coefficient of the screen can be changed by adjusting the refractive index of the water mist, so that the brightness of the screen is not more than the maximum value of the preset brightness interval. Therefore, the refractive index of the screen is a ratio of the maximum value of the preset brightness interval to the current illuminance of the ambient light. Further, the refractive index of the water mist can be calculated. Specifically, a ratio of the maximum value of the preset luminance section to the illuminance of the current ambient light (which may be referred to as a third ratio) may be calculated, a difference of 1 from the square root of the third ratio (which may be referred to as a third difference) may be calculated, and a product of the third difference and the refractive index of the screen (which may be referred to as a second product) may be calculated. Then, a sum of the square roots of 1 and the third ratio (which may be referred to as a third sum) is calculated, and a ratio of the second product and the third sum (which may be referred to as a fourth ratio) which is the refractive index of the water mist is calculated.
Then, the host computer can calculate the product of the refractive index which needs to be supplemented currently and the preset coefficient, and obtain the concentration (namely the target concentration) of the water mist which needs to be sprayed by the atomizer currently. The preset coefficient may be set by a skilled person based on experience, for example, the preset coefficient may be any value of [0,1 ].
Further, the host may send control instructions to the nebulizer. Accordingly, the nebulizer can spray water mist of a target concentration in a designated area between the eyes of the user and the screen to reduce the brightness of the screen.
In addition, if it is determined that the current illuminance of the ambient light is greater than the second illuminance threshold, which indicates that the brightness of the screen is high and is not suitable for the user to view, if the light source in the current vehicle is in an on state, the host may turn off the light source in the vehicle to reduce the brightness of the screen.
Referring to fig. 6, fig. 6 is a schematic diagram of a designated area according to an embodiment of the present invention. The atomizer is installed below the screen. Point a represents the exit of the atomizer spraying the water mist.
The designated area is: from the line between the atomizer outlet spraying water mist (i.e., point a) and any point of the screen (any point in the lower edge of the screen in fig. 6) to the sector area formed by the line between the atomizer outlet spraying water mist and the position of the eyes of the user.
The position of the eyes of the user may be represented by the position of any point on the upper edge of the driver seat, or may also be represented by the position of any point on the upper edge of the passenger seat, which is not specifically limited in the embodiment of the present invention.
Referring to fig. 7, fig. 7 is a flowchart of another screen brightness adjusting method according to an embodiment of the present invention.
S11: from 2 pm to 6 am, it is determined whether the current illuminance of the ambient light is less than the first illuminance threshold, if so, step S131 is executed, and if not, step S14 is executed.
S12: and in other time periods, judging whether the current illuminance of the ambient light is less than a third illuminance threshold, if so, executing step S132, and if not, executing step S14.
For steps S11 and S12, the host computer may acquire the illuminance of the current ambient light of the vehicle detected by the illuminance sensor. Then, if the current time belongs to 2 pm to 6 am, the host may determine whether the current illuminance of the ambient light is less than a first illuminance threshold (e.g., 8 lx) corresponding to 2 pm to 6 am. If the current time is a time period other than 2 pm to 6 am, the host computer may determine whether the current illuminance of the ambient light is less than a third illuminance threshold (e.g., 15 lx) corresponding to the other time periods.
S131: and turning on a light source in the vehicle, and adjusting the brightness of the light source in the vehicle according to the current illuminance of the ambient light.
In one implementation, if the current ambient light illuminance is less than the first illuminance threshold during the time period from 2 pm to 6 am, it indicates that the current brightness of the screen is low. During a period of time other than 2 pm to 6 am, if the current illuminance of the ambient light is less than the third illuminance threshold, it indicates that the current brightness of the screen is low. Therefore, the host computer can turn on the light source in the vehicle and increase the brightness of the screen by adjusting the brightness of the light source in the vehicle.
S132: and turning on a light source in the vehicle, and adjusting the brightness of the light source in the vehicle according to the current illuminance of the ambient light.
S14: the light source in the vehicle is turned off.
In one implementation, if the current ambient light illuminance is not less than the first illuminance threshold during the time period from 2 pm to 6 am, it indicates that the current brightness of the screen is high. In other time periods other than 2 pm to 6 am, if the current illuminance of the ambient light is not less than the third illuminance threshold, it indicates that the current brightness of the screen is high. Thus, the host machine may turn off the light source in the vehicle if the light source in the vehicle has been turned on.
S15: and judging whether the current illumination of the ambient light is greater than a second illumination threshold value, and if so, executing step S16.
S16: the water mist sprayed by the atomizer changes the reflection coefficient of the screen.
For steps S15 and S16, the host may determine whether the current ambient light illuminance is greater than a second illuminance threshold (e.g., 3334 lx). If the current ambient light illumination is greater than the second illumination threshold, the current brightness of the screen is high and the screen is not suitable for being watched by human eyes. Therefore, the host can determine the target concentration of the water mist which needs to be sprayed by the atomizer according to the current illuminance of the ambient light and the refractive index of the screen, and then the reflection coefficient of the screen is changed through the water mist with the target concentration sprayed by the atomizer so as to reduce the brightness of the screen.
Referring to fig. 8, fig. 8 is a structural diagram of a brightness adjusting system according to an embodiment of the present invention. The brightness adjustment system includes: host computer, screen, sunshine rainfall sensor, atomizer and supplementary light source.
The solar-rain sensor may detect the current illuminance of the ambient light of the vehicle and transmit the current illuminance of the ambient light to the host. If the host determines that the current ambient light illumination is less than the first illumination threshold, it indicates that the current brightness of the screen is low. Therefore, the host can adjust the light source in the vehicle according to the current illuminance of the ambient light and the reflection coefficient of the screen, so that the brightness of the adjusted screen is not less than the preset brightness threshold value, and the brightness of the screen is increased. If the host determines that the current ambient light illumination is not less than the first illumination threshold, it indicates that the current brightness of the screen is high. Thus, if the light source in the vehicle is in an on state, the host machine may turn off the light source in the vehicle.
And if the host determines that the current ambient light illumination is greater than the second illumination threshold, indicating that the current brightness of the screen is higher. Therefore, the host can determine the target concentration of the water mist which needs to be sprayed by the atomizer according to the current illuminance of the ambient light and the refractive index of the screen, and send a control instruction to the atomizer. Accordingly, the nebulizer may spray water mist of a target concentration in a designated area between the screen and the eyes of the user to reduce the brightness of the screen. In addition, if the host determines that the current illuminance of the ambient light is greater than the second illuminance threshold, it indicates that the current brightness of the screen is high. Thus, if the light source in the vehicle is in an on state, the host machine may turn off the light source in the vehicle.
