Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The application provides a screen brightness adjusting method based on screen angles, which aims to realize accurate simulation of screen light to ambient light through a screen brightness compensation adjusting model and reduce deviation between the screen light brightness and the ambient light brightness. Compared with the conventional screen light adjusting method, the method generally detects the ambient light brightness through the light sensing element, and correspondingly adjusts the screen brightness to the brightness detection value of the ambient light. Because the light sensing detection element is generally arranged on one side of the screen, when the light sensing detection element is used for detecting ambient light, only the light source facing the screen can be detected, and the detection result has certain loss degree. Moreover, the loss degree of the detection result is different due to different placement angles of the screen. Because the environment light source that human eyes and screen experienced is different, if there is the error in the environment light source that the screen detected, direct ambient light simulation based on luminance detected value, the screen light that can make human eyes experience can have certain visual deviation with environment light source. Therefore, the screen brightness adjusting method based on the screen angle is provided to solve the technical problems that the existing screen light is not accurately adjusted and the screen light and the ambient light have deviation.
The first embodiment is as follows:
fig. 1 is a flowchart of a screen brightness adjusting method based on a screen angle according to an embodiment of the present disclosure, where the screen brightness adjusting method based on a screen angle provided in this embodiment may be executed by a screen brightness adjusting device based on a screen angle, the screen brightness adjusting device based on a screen angle may be implemented in a software and/or hardware manner, and the screen brightness adjusting device based on a screen angle may be formed by two or more physical entities or may be formed by one physical entity. Generally, the screen brightness adjusting device based on the screen angle may be a smart device such as a tablet, a computer, and a mobile phone.
The following description will be given taking the screen brightness adjustment apparatus based on screen angle as an example of a subject that performs the screen brightness adjustment method based on screen angle. Referring to fig. 1, the screen brightness adjusting method based on the screen angle specifically includes:
s110, a screen brightness compensation adjustment model is constructed in advance according to a specified mapping relation, wherein the specified mapping relation is the mapping relation between the actual brightness value and the brightness detection value of the ambient light under different screen angles.
Specifically, in order to enable the screen light to accurately simulate the indoor ambient light, the loss degree of the screen light sensation detection element for detecting the ambient light at different screen angles needs to be determined, and the screen brightness compensation adjustment model is further established based on the measured loss degree, so that the accurate adjustment of the screen brightness is realized. Before that, the loss degree of the light sensing detection element on the ambient light at different screen angles is determined by constructing a mapping relation between the actual brightness value and the brightness detection value of the ambient light at different screen angles.
For example, the embodiment of the application determines the actual detection condition of the indoor ambient light by detecting the indoor ambient light in the indoor environment. And further, the screen light source detection is carried out by adjusting different screen angles through intelligent equipment (such as a flat plate), and the screen light source detection conditions under different screen angles are determined. Taking a scene in which a user holds a tablet as an example, generally, the screen angle of the tablet is approximately between 0 ° and 90 ° from horizontal placement to vertical placement. When the screen light source detection is carried out, three screen angles of 35 degrees, 45 degrees and 90 degrees are selected for carrying out the light source detection. For the actual detection of the indoor ambient light, the light sensing detecting element can be placed at a position where the light sensing detecting element can completely receive the light, so that the finally obtained actual detection condition of the indoor ambient light can be close to the actual condition of the ambient light enough, and the detection result is used as the actual brightness value of the ambient light. In order to ensure the accuracy of the actual detection of the indoor ambient light, it is necessary to eliminate the interference of the outdoor ambient light during detection. According to the embodiment of the application, three light sources such as a living room headlamp, a desk lamp and a bedside lamp are adopted for carrying out indoor environment light actual detection and screen light source detection, so that a corresponding real environment light source detection table and a corresponding screen light source detection table are obtained. Wherein, the environment light source detection table is as follows:
table 1: real environment light source detecting meter
| External light source | Time state | Test results (lux) |
| Living room headlight | Eliminating external outdoor ambient light interference | 200～500lux |
| Study desk lamp | Eliminating external outdoor ambient light interference | 300～1000lux |
| Bedroom bedside lamp | Eliminating external outdoor ambient light interference | 100～300lux |
The screen light source detection table is as follows:
table 2: screen light source detecting meter
Based on the above tables 1 and 2, the mapping relationship between the actual brightness value and the brightness detection value of the ambient light at different screen angles in the indoor environment can be determined. It should be noted that, in the actual detection process, the number of samples of the detection data may be adaptively increased according to the requirement of the experimental precision, so as to ensure that the finally determined mapping relationship has sufficient representativeness. In some embodiments, the real environment light source detection may be performed by combining with an external environment light source, and a mapping relationship between an actual brightness value and a brightness detection value of the environment light at different screen angles is constructed.
Further, the screen brightness compensation adjustment model includes a brightness detection loss value calculation formula corresponding to the brightness detection value, and the brightness detection loss value calculation formula is constructed based on the specified mapping relationship. In order to accurately simulate indoor ambient light, the screen brightness compensation adjustment model needs to extract a brightness detection value of the ambient light on one hand, and needs to calculate a brightness value which is detected and lost by the screen relative to an actual brightness value of the ambient light when the screen detects the ambient light on the other hand. And combines the two luminance values, which is considered to be equivalent to the actual luminance value of the current ambient light. And determining the screen brightness value mapped to the screen, namely the screen brightness adjusting value according to the specified mapping relation. And defining the brightness value lost in the screen detection process as a brightness detection loss value. The brightness detection loss value can be determined according to the above mapping relationship, and it can be understood that, based on the current screen angle and the use environment, the approximate range of the brightness detection loss value can be determined by correspondingly querying the table 1 and the table 2. Based on the above, a brightness detection loss value calculation formula is constructed through the mapping relation, and brightness detection loss values lost by screen brightness detection at different angles are calculated through the brightness detection loss value calculation formula.
Wherein the luminance detection loss value calculation formula includes a first loss value calculation formula or a second loss value calculation formula, and the first loss value calculation formula is:
l1＝l0*sinθ
the second loss value calculation formula is as follows:
l1＝l0*cosθ
wherein l1For brightness detection of loss value, /)0θ is a screen angle for the luminance detection value.
And calculating a brightness detection loss value by using a trigonometric function based on the mapping relation so as to represent a brightness detection value which is probably lost in the screen brightness detection process. It should be noted that the above-mentioned luminance detection loss value calculation formula is only a measurement and calculation method for the ambient light luminance detection loss situation constructed based on the mapping relationship. In some embodiments, other luminance detection loss value calculation formulas can be further constructed according to the mapping relationship between the actual luminance value of the ambient light and the luminance detection value, and the measurement and calculation mode of the ambient light luminance detection loss condition is not fixedly limited in the embodiments of the present application.
And further constructing the screen brightness compensation adjustment model according to the brightness detection loss value calculation formula. The screen brightness compensation adjustment model is as follows:
L＝wlg(l0+l1)
wherein, L is the screen brightness adjusting value, w is the parameter factor, L0In order to detect the brightness value, a brightness value is set,l1the loss value is detected as brightness.
It is understood that, in the above-mentioned screen brightness compensation adjustment model, "l0+l1"is the sum of the detected value of the screen brightness and the loss value of the brightness detection, and ideally, the value is the actual brightness value of the corresponding ambient light. On the other hand, for the parameter factor w, it is required that under the ideal condition (i.e. no loss of screen brightness detection), the relationship between the brightness detection value and the parameter factor is l0＝wlgl0The screen brightness adjustment value calculated in this way can be as close as possible to the actual brightness value of the current ambient light. In addition, the screen brightness compensation adjustment model of the embodiment of the application uses a logarithmic function, and according to the function curve characteristic of the logarithmic function, the function curve characteristic follows l0+l1"the value of" is gradually increased. Further, as the function curve becomes more gentle in the future, the value thereof tends to be more stable and does not increase excessively. Therefore, the screen brightness can be regulated below a certain upper limit, and the visual comfort degree is prevented from being influenced by overlarge screen brightness.
In one embodiment, the brightness detection loss value calculation formula is further selected or switched to be the first loss value calculation formula or the second loss value calculation formula according to the self-defined adjustment data of the screen brightness. Since the user often has the situation of manually adjusting the screen brightness in the process of using the screen, the operation of manually adjusting the screen brightness is the self-defined adjustment data. The brightness detection loss value is calculated by selecting the first loss value calculation formula or the second loss value calculation formula according to the use condition of the user and the use condition of the user screen angle. And adaptively increasing or decreasing the brightness detection loss value, and adding the part of the user-defined screen brightness adjustment into the brightness detection loss value calculation adjustment. For example, according to the user's habit, the screen angle is usually set at 35 ° for use. And detects that the user often manually increases the screen brightness. The luminance detection loss value calculation formula is selected accordingly, and since cos35 ° is greater than sin35 °, the second loss value calculation formula is selected to calculate the luminance detection loss value. And then the screen brightness adjusting value finally calculated by the screen brightness compensation adjusting model is relatively larger (compared with the screen brightness adjusting value calculated by the screen brightness compensation adjusting model comprising the second loss value calculation formula). Therefore, the finally obtained screen brightness adjusting value can be more suitable for the use requirement of a user. After that, if it is detected that the screen brightness is manually turned down by the user for the set number of times, the brightness detection loss value calculation formula is switched to the first loss value calculation formula according to the user usage habit. It can be understood that, at this time, the luminance detection loss value obtained by calculation is relatively small, and the screen luminance adjustment value finally obtained by calculation through the screen luminance compensation adjustment model is also relatively small. Therefore, the method adapts to the use condition that the screen brightness is often manually reduced by the user, and the finally obtained screen brightness adjusting value is more suitable for the use requirement of the user.
S120, collecting the brightness detection value of the current ambient light, and collecting the current screen angle of the screen.
S130, inputting the collected brightness detection value and the screen angle into the screen brightness compensation adjustment model, outputting a corresponding screen brightness adjustment value, and adjusting the current screen brightness to the screen brightness adjustment value.
Specifically, after the screen brightness compensation adjustment model is constructed, real-time screen brightness adjustment can be performed based on the screen brightness compensation adjustment model. Illustratively, when the screen is opened for use, the ambient light brightness information is collected through the light sensing detection element arranged on one side of the screen, and then the brightness detection value of the current ambient light is determined. On the other hand, the current screen angle is detected by a three-axis sensor built in the indoor ambient light adjusting device of the screen angle.
Further, according to the detected brightness detection value and the screen angle, the screen brightness compensation adjustment model of the above S110 is used for calculation. The brightness detection loss value is determined by using a brightness detection loss value calculation formula based on the brightness detection value and the screen angle, and then the final screen brightness adjustment value is calculated according to a screen brightness compensation adjustment model calculation formula. It is understood that, according to the formula conversion, the screen brightness compensation adjustment model calculation formula can be expressed as:
L＝wlg(l0+l0*sinθ) (1)
or
L＝wlg(l0+l0*cosθ) (2)
Then the detected brightness detection value and the screen angle are input into the above formula (1) or (2), and the final screen brightness adjustment value can be obtained. And further adjusting the current screen brightness based on the brightness adjustment value, and adjusting the current screen brightness to the screen brightness adjustment value, thereby completing the screen brightness adjustment based on the screen angle in the embodiment of the application.
In one embodiment, in order to make the screen brightness in a proper interval and avoid the situation that the screen is too bright or too dark, the screen brightness adjusting device based on the screen angle may also preset a screen brightness adjusting interval. And calculating a screen brightness adjusting value based on a preset screen brightness adjusting interval and according to the screen brightness compensation adjusting model. And according to the set screen brightness adjusting interval, when the screen brightness adjusting value calculated by the screen brightness compensation adjusting model exceeds the upper limit of the screen brightness adjusting interval, outputting the screen brightness adjusting value by taking the upper limit of the screen brightness adjusting interval as the screen brightness adjusting value. And when the screen brightness adjusting value calculated by the screen brightness compensation adjusting model is lower than the lower limit of the screen brightness adjusting interval, outputting the screen brightness adjusting value by taking the lower limit of the screen brightness adjusting interval as the screen brightness adjusting value. Therefore, the technical problem that the visual comfort of a user is influenced by directly simulating ambient light due to the fact that the actual brightness of the ambient light is too bright or too dark can be avoided.
The screen brightness compensation adjustment model is constructed in advance according to the specified mapping relation, the brightness detection value of the current ambient light is collected when the screen is opened, the current screen angle of the screen is collected, the collected brightness detection value and the collected screen angle are input into the screen brightness compensation adjustment model, the corresponding screen brightness adjustment value is output, and finally the current screen brightness is adjusted to the screen brightness adjustment value. By adopting the technical means, the external environment light can be accurately simulated when the screen brightness is adjusted, the accuracy of the screen brightness adjustment is improved, the influence of brightness deviation on the visual comfort level is avoided, and the visual experience of a user is further optimized.
Example two:
on the basis of the foregoing embodiment, fig. 2 provides a flowchart of another screen brightness adjustment method based on a screen angle according to the second embodiment of the present application, and referring to fig. 2, the screen brightness adjustment method based on a screen angle specifically includes:
s210, constructing a screen brightness compensation adjustment model in advance according to a specified mapping relation, wherein the specified mapping relation is the mapping relation between the actual brightness value and the brightness detection value of the ambient light under different screen angles;
s220, collecting the brightness detection value of the current ambient light, and collecting the current screen angle of a screen;
s230, inputting the collected brightness detection value and the collected screen angle into the screen brightness compensation adjustment model, outputting a corresponding screen brightness adjustment value, and adjusting the current screen brightness to the screen brightness adjustment value;
s240, gradually increasing the brightness of the screen according to the service time of the screen, outputting a fatigue use prompt when the brightness of the screen reaches a set upper limit value of the brightness of the screen, and continuously keeping the brightness of the screen at the upper limit value of the brightness of the screen.
Specifically, according to the embodiment of the application, after the current screen brightness is adjusted to the screen brightness adjusting value, in order to optimize the visual experience, the visual comfort level is improved, and the visual comfort level of a user is improved by gradually adjusting the screen brightness. As the use time of the screen is gradually increased, the human eyes can have the situations of no perception fatigue and even perception fatigue. When eye fatigue occurs, the requirement of human eyes on the screen brightness is gradually increased along with the eye fatigue. Therefore, in order to improve the visual comfort of the user, the brightness of the screen needs to be gradually increased along with the use time of the screen.
Furthermore, in the process of gradually increasing the screen brightness along with the use duration, fatigue use prompt is carried out according to a preset upper limit value of the screen brightness. When the screen brightness is adjusted to the upper limit value of the screen brightness, the eye fatigue of the current user is over high, and the screen is not suitable to be used excessively. Based on the screen angle, the screen brightness adjusting device outputs and displays a fatigue use prompt message on the screen to prompt the user of the current fatigue use condition. Further, a selection box may be provided, including "continue use" and "close screen" options for selection by the user. If the user selects "close screen", the screen brightness adjustment device based on the screen angle closes the screen display in response to this selection. If the user selects 'continue use', the current screen brightness is continuously kept at the upper limit value of the screen brightness, and the screen brightness is not increased along with the use time.
In one embodiment, different upper limit values of the screen brightness are set according to the eye fatigue level of the user. Before that, the screen brightness adjusting device based on the screen angle establishes a mapping relation between a fatigue level and an upper limit value of the screen brightness in advance, wherein one fatigue level corresponds to one upper limit value of the screen brightness. And, the higher the fatigue level is, the higher the corresponding upper limit value of the screen brightness is. When the brightness of the screen is gradually increased along with the use duration, the eye images of the user are collected through the front-mounted camera of the collecting screen in real time, the eye image characteristics are identified, and the fatigue level of the user is determined according to the identified eye image characteristics. And further inquiring the corresponding mapping relation according to the determined fatigue grade, so that the corresponding upper limit value of the screen brightness can be determined. Based on the upper limit value of the screen brightness, the screen brightness is gradually increased along with the increase of the duration of using the screen by the user until the upper limit value of the screen brightness is reached, and fatigue use prompt is carried out. In addition, in the process of adjusting the screen brightness, if the fatigue level of the eyeballs of the user does not change, after the screen brightness is adjusted to the corresponding upper limit value of the screen brightness, the upper limit value of the screen brightness is kept to be displayed, and the screen brightness is adjusted again when the next fatigue level changes, otherwise, the upper limit value of the screen brightness is kept to be displayed continuously.
According to the embodiment of the application, the brightness of the screen is gradually increased when the screen is used along with the screen, the visual experience of a user can be further optimized, the fatigue use prompt is output when the brightness of the screen reaches the upper limit value of the brightness of the set screen, the user can be timely reminded of the excessive use condition, and the eye health is guaranteed.
