The application provides a screen light adjusting method, aims at carrying out the adaptability of screen luminance and colour temperature based on screen duration of use to this comes to adapt to user's visual fatigue and carries out the screen light adjustment, and then promotes user's visual comfort level. For the conventional screen light adjusting method, when the screen light is adjusted, the brightness and the color temperature of the screen light are generally automatically adjusted according to the brightness and the color temperature of the real-time ambient light, so as to realize the adaptive adjustment of the screen. Or the screen brightness and the color temperature are set by the user in a self-defined way by adopting a manual adjustment mode. The two screen adjusting modes are relatively single, the influence of the visual fatigue of a user cannot be well considered, adaptive screen adjustment is not performed according to the using time, and the adjusting effect is general. According to the requirement of visual comfort level (VICO) index, the screen light meets the health and safety requirements of human body in physiological and psychological aspects, namely the influence of user visual fatigue in the using process of the screen is considered. Therefore, the screen light adjusting method provided by the embodiment of the application is provided to solve the technical problems of single screen adjusting mode and poor adaptability in the prior art.
The first embodiment is as follows:
fig. 1 is a flowchart of a screen light adjusting method according to an embodiment of the present disclosure, where the screen light adjusting method provided in this embodiment may be executed by a screen light adjusting device, the screen light adjusting device may be implemented in a software and/or hardware manner, and the screen light adjusting device may be formed by two or more physical entities or may be formed by one physical entity. Generally, the screen light adjusting device may be a smart device such as a tablet, a computer, or a mobile phone.
The following description will be given taking a screen light adjusting apparatus as an example of a main body that performs the screen light adjusting method. Referring to fig. 1, the screen light adjusting method specifically includes:
and S110, detecting the ambient light brightness value and the ambient light color temperature value in real time.
When the screen light is adjusted, the embodiment of the application firstly detects the external environment light in real time. And determining an ambient light brightness value and an ambient light color temperature value based on the external ambient light detected in real time, so as to correspondingly adjust the initial brightness value of the screen based on the ambient light brightness value and correspondingly adjust the initial color temperature value of the screen based on the ambient light color temperature value. The ambient light brightness information is collected through a light sense detection element arranged on the screen adjusting device, and then the current ambient light brightness value is determined. On the other hand, the RGB sensor is used for collecting the ambient light color temperature information, and then the current ambient light color temperature value is determined.
Illustratively, the screen light adjusting device triggers the ambient light detection when the screen is turned on, collects the ambient light brightness value and the ambient light color temperature value, and then performs the screen light adjustment. In some embodiments, the light sensing element and the RGB sensor on the screen light adjusting device perform the ambient light detection in real time after the device is turned on (i.e. no matter whether the screen is turned on), and correspondingly perform the screen light adjustment when the screen is turned on according to the detected ambient light brightness value and the ambient light color temperature value.
S120, determining and adjusting an initial brightness value of the screen based on a first mapping relation between preset ambient light brightness and screen initial brightness, and determining and adjusting an initial color temperature value of the screen based on a second mapping relation between preset ambient light color temperature and screen initial color temperature.
Further, based on the ambient light brightness value and the ambient light color temperature value collected in step S110, when performing screen light adjustment, different from a conventional screen light adjustment mode, the screen light adjustment device according to the embodiment of the present application does not directly adjust the brightness and the color temperature of the screen light to be equal to the ambient light brightness value and the ambient light color temperature value according to the collected ambient light brightness value and the collected ambient light color temperature value. But determines the initial brightness value and the initial color temperature value of the screen according to the preset mapping relation. The mapping relation between the ambient light brightness and the screen initial brightness is defined as a first mapping relation, and the mapping relation between the ambient light color temperature and the screen initial color temperature is defined as a second mapping relation. It is understood that, based on the first mapping relationship, the initial brightness value of the corresponding mapped screen can be determined according to the detected ambient light brightness value. Based on the second mapping relationship, the initial color temperature value of the screen corresponding to the mapping can be determined according to the detected ambient light color temperature value.
Specifically, referring to fig. 2, the determining of the adjustment flow of the initial brightness value includes:
s1201, a first mapping relation between the ambient light brightness and the screen initial brightness is established in advance based on a first set interval of the screen initial brightness value;
s1202, determining an initial brightness value of a screen according to the ambient light brightness value and the first mapping relation;
s1203, adjusting the brightness value of the current screen to be the initial brightness value.
In the embodiment of the application, a brightness value interval is preset corresponding to the initial brightness value, the brightness value interval is defined as a first set interval, and the initial brightness value of the screen light is within a reasonable range, and cannot be higher or lower by setting the brightness value interval. In addition, in order to provide better visual experience, the first mapping relationship of the embodiment of the application needs to simulate the ambient light, so that the initial brightness value of the screen light is as close as possible to the ambient light brightness value. It can be understood that, since the external environment light is the light with the strongest adaptability to human eyes, in order to improve the visual comfort of human eyes, the screen is required to simulate the ambient light, so that the brightness of the light emitted by the screen reaches the effect of being close to the external environment. Wherein, the first mapping relation formula is as follows:
l1＝wlg(l0*(1+0.05％))
wherein l1Is the initial brightness value of the screen, with lux (lux), w as a parameter factor, l0Is the ambient light brightness value. It should be noted that, in order to make the brightness of the light emitted initially by the screen reach the effect of being close to the external environment, in the first mapping relation formula, the relation between the brightness value of the ambient light and the parameter factor is required to be l0＝wlgl0The initial brightness value l calculated by this1Can be as close to ambient light level as possible.
Then, based on the first mapping relation formula and the real-time detected ambient light brightness value, the initial brightness value of the current screen can be determined, and the brightness of the screen light is adjusted to the initial brightness value.
In the embodiment of the present application, since the first setting section of the initial brightness value is provided, when the initial brightness value is calculated based on the first mapping relation formula, if the calculated value exceeds the upper limit or the lower limit of the first setting section, the upper limit or the lower limit of the first setting section is directly used as the initial brightness value of the screen. Therefore, the problem that the appearance of the screen is influenced by directly simulating the ambient light when the ambient light is too bright or too dark can be avoided.
On the other hand, referring to fig. 3, the determination of the initial color temperature value adjusts the flow including:
s1204, a second mapping relation between the ambient light color temperature and the screen initial color temperature is pre-established in a second set interval based on the screen initial color temperature value;
s1205, determining an initial color temperature value of the screen according to the ambient light color temperature value and the second mapping relation;
and S1206, adjusting the color temperature value of the current screen to be the initial color temperature value.
Similarly, in the embodiment of the present application, a color temperature value interval is preset corresponding to the initial color temperature value, the color temperature value interval is defined as a second setting interval, and the color temperature value interval is set, so that the initial color temperature value of the screen light is within a reasonable range, and cannot be higher or lower. In addition, in order to provide better visual experience, the second mapping relationship of the embodiment of the application needs to simulate ambient light, so that the initial color temperature value of the screen light is as close to the ambient light as possible. Different from the brightness adjustment method, in the embodiment of the present application, when the initial color temperature value is adjusted, the color temperature effect of a cold tone (e.g., the color temperature of the ambient light at the beginning of the sun) is first adjusted, and then the color temperature effect of adjusting the color temperature to a warm tone (e.g., the color temperature of the ambient light at noon) is implemented. Wherein the second mapping relation formula is:
S1＝S0*10％+6000
wherein, S1Is the initial color temperature value of the screen and has the unit of K (Kelvin) and S0Is the color temperature value of the ambient light. Then, based on the first mapping relation formula and the real-time detected ambient light color temperature value, the initial color temperature value of the current screen can be determined, and further, the brightness of the screen light is adjusted to the initial color temperature value. It can be understood that the initial color temperature value is above 6000K, so as to simulate the color temperature of the ambient light at the initial rise of the sun.
It should be noted that, because the second setting interval of the initial color temperature value is set in the embodiment of the present application, the second setting interval may be 4000 to 7000K. When the initial color temperature value is calculated based on the second mapping relation formula, if the calculated value exceeds the upper limit of the second setting interval (generally, the initial color temperature value is more than 6000K, and the color temperature value is not lower than the lower limit of the second setting interval), the upper limit of the second setting interval (i.e. 7000K) is directly used as the initial color temperature value of the screen. Therefore, the problem that the initial color temperature value obtained by calculation influences the screen appearance when the color temperature of the ambient light is too cold can be avoided.
Moreover, the first mapping relation formula and the second mapping relation formula are only one way to determine the initial color temperature value and the initial brightness value in the application embodiment. In some embodiments, the first mapping relation formula and the second mapping relation formula may be set according to actual adjustment requirements, and the embodiments of the present application are not limited herein.
And S130, gradually adjusting the real-time brightness value of the screen by using a set brightness adjusting algorithm according to the screen use duration based on the initial brightness value, and simultaneously gradually adjusting the real-time color temperature value of the screen by using a set color temperature adjusting algorithm according to the screen use duration based on the initial color temperature value.
Further, after the initial color temperature value and the initial brightness value of the screen are determined and adjusted, in order to meet different requirements of different visual fatigue degrees on screen light in the using process of the screen, the real-time brightness value and the real-time color temperature value of the screen are adjusted along with the using time of the screen in the embodiment of the application. Among them, according to the demand of visual comfort level (VICO) index, along with the increase of visual fatigue, in order to promote visual comfort level, it is necessary to adaptively adjust the luminance and the color temperature of light to a warmer tone. Therefore, in order to improve visual comfort, it is necessary to gradually increase the screen brightness and decrease the screen color temperature along with the use time.
The method comprises the following steps of gradually adjusting the real-time brightness value of a screen by using a set brightness adjusting algorithm according to the service time of the screen, wherein the brightness adjusting algorithm comprises the following steps:
L＝wlg(l0*(1+0.05％*t))
wherein, L is the real-time brightness value of the screen, the unit is lux (lux), w is a parameter factor, the value of the parameter factor is referred to a first mapping relation formula, L0The ambient light brightness value is, and t is the screen use duration. The brightness adjusting algorithm of the embodiment of the application is derived based on the first mapping formula, and because the real-time brightness value of the screen needs to be adjusted step by step along with the use duration, the brightness adjusting algorithm introduces the time parameter t on the basis of the first mapping relation formula. The real-time brightness value calculation formula obtained by the method has the value which is gradually increased along with the increase of the use time, namely the real-time brightness value is gradually increased along with the use time. In addition, the brightness adjustment algorithm of the embodiment of the application uses a logarithmic function, and according to the function curve characteristic of the logarithmic function, the value of the brightness adjustment algorithm is gradually increased along with the increase of the use duration. Further, as the function curve becomes more gentle in the future, the value thereof tends to be more stable and does not increase excessively. Thereby ensuring real-time brightnessThe value is adjusted below a certain upper limit, so that the visual comfort degree is prevented from being influenced by overlarge screen brightness.
On the other hand, the real-time color temperature value of the screen is gradually adjusted by using a set color temperature adjusting algorithm according to the service time of the screen, wherein the color temperature adjusting algorithm is as follows:
S＝(S0*10％+6000)*(1-1％*t) Smin≤S≤Smax
wherein S is the real-time color temperature value of the screen, and the unit is K (Kelvin), S0Is the ambient light color temperature value, SminLower limit of color temperature of screen, SmaxAnd t is the screen use duration. Similarly, the color temperature adjustment algorithm in the embodiment of the present application is derived based on the second mapping formula. Since the real-time color temperature value of the screen needs to be adjusted step by step along with the use duration, the color temperature adjusting algorithm introduces the time parameter t on the basis of the second mapping relation formula. According to the real-time color temperature value calculation formula obtained by the method, as the use time length increases, the value of the real-time color temperature value is gradually reduced (adjusted from a cold color tone to a warm color tone), namely, the real-time color temperature value is gradually reduced along with the use time length. In addition, the value of the real-time color temperature value of the embodiment of the application is Smin～SmaxS ofmin～SmaxThe value can be 4000K to 7000K. The real-time color temperature value is generally between 4000K to 7000K, the initial color temperature value is not higher than 7000K, the color temperature is reduced to 4000K along with the increase of the using time, and then the color temperature value 4000K is kept for displaying, so that the adjustment of the real-time color temperature value is completed.
It should be noted that the screen usage time t is set according to actual adjustment requirements, and may be 30S, 1 minute, or 5 minutes. And according to the actual screen light adjusting requirement, other screen brightness adjusting algorithms and color temperature adjusting algorithms can be adaptively selected, and the embodiment of the application does not make fixed limitation on a specific adjusting formula, and particularly aims to realize that the screen brightness is increased and the screen color temperature is reduced along with the use time.
In one embodiment, when the screen light adjusting device detects that the change of the ambient light brightness value reaches a set first change threshold, the initial brightness value of the screen is determined again based on the new ambient light brightness value, and the real-time brightness value of the screen is adjusted according to the determined initial brightness value. For example, when the environment in which the screen is used changes (i.e. the change of the ambient light brightness value reaches the set first change threshold), in order to adapt the screen to the changed environment, the initial brightness value of the screen light needs to be readjusted so that the new initial brightness value approaches the new ambient light brightness value. After that, the real-time brightness value of the screen light is adjusted stepwise following the use period based on the newly determined initial brightness value. The adjustment method of the real-time luminance value refers to the step S130, which is not described herein again.
On the other hand, in one embodiment, the screen color temperature that changes in the use environment is also readjusted. When the screen light adjusting device detects that the change of the ambient light color temperature value reaches a set second change threshold value, the initial color temperature value of the screen is determined again based on the new ambient light color temperature value, and the real-time color temperature value of the screen is adjusted according to the determined initial color temperature value. For example, when the screen usage environment changes (i.e. the change of the color temperature value of the ambient light reaches the set second change threshold), in order to adapt the screen to the changed environment, the initial color temperature value of the screen light needs to be readjusted to adapt the new initial color temperature value to the new usage environment.
