Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a vision protection system, which adaptively adjusts the brightness of a mobile phone screen by setting the dual calibration of the light intensity irradiated on the mobile phone screen and the mobile phone use duration, thereby realizing semi-enhanced control of the mobile phone use duration, effectively preventing the vision from being degraded by controlling the mobile phone use duration, and actively developing the self-control ability of playing the mobile phone.
The mobile phone color matching and brightness correction system specifically comprises a light intensity sensing unit 1, a color matching selection unit 2, a self-adaptive brightness adjustment unit 3, a mobile phone use time counting unit 4 and a brightness correction unit 5.
The light intensity sensing unit 1 is used for sensing the light intensity of the external environment on the screen of the mobile phone.
The color matching selection unit 2 provides a plurality of mobile phone screen background colors for improving the comfort of human eyes, and a self-defining unit for adjusting the saturation level of each mobile phone screen background color.
According to the embodiment, personalized eyesight protection aiming at different crowds is realized by self-defined selection or regulation of the background color of the mobile phone screen and the background color saturation of the mobile phone screen.
According to research, the absorption and reflection of light rays are different from color to color, the people feel tired due to excessively bright color, and the people feel heavy due to excessively dark color. Red is 67% reflective to light, yellow is 65%, green is 47%, and cyan is only 36%. Because red and yellow reflect light more strongly, so it is easy to produce glare, and cyan and green absorb and reflect light more moderately, so it is more suitable for nervous system, cerebral cortex and retina tissue in eyes of human body, and brings cool and calm feeling to people. Therefore, it is common that the eyes look at green and cyan screens, which is comfortable.
Therefore, the mobile phone screen background colors provided by the color matching selection unit 2 of the embodiment include, but are not limited to, cyan, green and yellow, and the custom unit is used for adjusting the saturation of the cyan, green and yellow, and the adjustment range of the saturation of each mobile phone screen background color is 40-80%.
The user can self-define and adjust the saturation of the mobile phone screen background colors with different colors according to different screen habits.
The self-adaptive brightness adjusting unit 3 adjusts the display brightness of the mobile phone screen according to the light intensity sensed by the light intensity sensing unit 1, and creates a functional relation between the external light intensity and the display brightness of the mobile phone screen.
In this embodiment, the adaptive brightness adjustment unit 3 sets a functional relationship between the light intensity of the external environment irradiated on the mobile phone screen and the display brightness of the mobile phone screen to be specifically: y is kx + b;
wherein y is the display brightness of the mobile phone screen, x is the external light intensity, k is greater than 0 and represents the proportional relation between y and x, and b is greater than 0 and represents the display brightness value of the mobile phone screen when the external light intensity is 0.
That is to say, the adaptive brightness adjusting unit 3 sets that the light intensity of the external environment on the mobile phone screen and the display brightness of the mobile phone screen are in a positive correlation, the greater the light intensity of the external environment on the mobile phone screen is, the greater the display brightness of the mobile phone screen is automatically adjusted by the adaptive brightness adjusting unit 3, the smaller the light intensity of the external environment on the mobile phone screen is, and the smaller the display brightness of the mobile phone screen is automatically adjusted by the adaptive brightness adjusting unit 3.
It should be added that the light intensity sensing unit 1 is mainly used for sensing the light intensity of the external environment on the mobile phone screen, and when the light intensity of the external environment on the mobile phone screen is not changed, the brightness correcting unit 5 performs secondary correction and modification on the standard mobile phone screen brightness.
The mobile phone service duration counting unit 4 is used for counting the duration of the used mobile phone screen, and the brightness correction unit 5 is used for secondarily correcting the display brightness of the mobile phone screen according to the mobile phone service duration.
In this embodiment, to better demonstrate the working principle of the brightness correction unit 5, the display brightness of the mobile phone screen corresponding to the light intensity of the external environment on the mobile phone screen is set as the standard data, and the brightness correction unit 5 is configured to secondarily correct the original display brightness of the mobile phone screen according to the usage duration of the mobile phone.
The brightness correction unit 5 sets a functional relationship between the mobile phone use duration and the mobile phone screen display brightness specifically as follows: y ═ y-wt;
wherein y' is the mobile phone screen brightness corrected by the brightness correction unit 5, y is the standard mobile phone screen display brightness, w is the relation coefficient between the mobile phone service duration and the mobile phone screen display brightness, and t is the mobile phone service duration.
That is, when the adaptive brightness adjusting unit 3 adjusts the brightness of the mobile phone screen to 50 according to the light intensity sensing unit 1, the maximum value of the brightness of the mobile phone screen is 100, and the minimum value of the brightness of the mobile phone screen is 0, and the usage duration of the mobile phone screen is timely counted by the mobile phone usage duration counting unit 4, the brightness correcting unit 5 continuously adjusts the brightness of the mobile phone screen according to the usage duration of the mobile phone screen, and reduces the brightness of the mobile phone screen from 50 to 49, 48, and 47 … ….
It should be particularly noted that the value of w is not constant, that is, w is not a fixed value, the value of w is related to the range corresponding to y, the larger the value range of the original mobile phone screen display brightness y is, the larger the relation coefficient w between the mobile phone use duration and the mobile phone screen display brightness is, the smaller the value range of the original mobile phone screen display brightness y is, and the smaller the relation coefficient w between the mobile phone use duration and the mobile phone screen display brightness is, so as to prevent the mobile phone screen display brightness from rapidly decreasing to the minimum value.
For example, when y is 80-100, w is a;
b, when y is 60-80;
c, when y is 40-60;
d, when y is 20-40;
when w is equal to e, y is 0-20;
and a > b > c > d > e > 0.
The minimum value of the mobile phone screen brightness corrected by the brightness correction unit 5 is less than b, and the mobile phone screen brightness corrected by the brightness correction unit 5 can be 0.
It should be noted that, the brightness correction unit 5 adjusts the usage duration of the mobile phone when the display brightness of the mobile phone screen is reduced to the minimum value, and controls the usage duration within 3 hours, and when the brightness of the mobile phone screen is reduced to 0, this means that the present embodiment implements semi-forced control of the user to continue using the mobile phone.
The user can manually adjust the brightness of the mobile phone screen, when the user manually adjusts the brightness of the mobile phone screen, the vision protection system reminds the user of allowing one-time adjustment or permanent adjustment, and when the user selects to allow one-time adjustment, the vision protection system reduces the brightness of the mobile phone screen to 0 within 1-3 min.
When the user selects to perform permanent adjustment or power off and restart the mobile phone, the adaptive brightness adjustment unit 3 and the brightness correction unit 5 work again to re-correct the display brightness of the screen.
When the brightness of the mobile phone screen is 0, the embodiment also counts the closing time of the mobile phone screen or the time when the brightness of the mobile phone screen is reduced to the minimum value by the mobile phone screen low brightness time counting unit 6, at this time, the mobile phone screen low brightness time counting unit 6 and the light intensity sensing unit 1 are incompatible and work independently, that is, when the brightness correcting unit 5 adjusts the brightness of the mobile phone screen to 0, the light intensity sensing unit 1 does not sense the light intensity of the external environment on the mobile phone screen actively any more, and the brightness of the mobile phone screen is maintained to be 0,
when the statistic value of the mobile phone screen low-brightness duration statistic unit 6 exceeds a set value, the self-adaptive brightness adjusting unit 3 automatically adjusts the mobile phone screen display brightness to be proper according to the light intensity sensing unit 1, and then the next brightness correction cycle is carried out.
Therefore, according to the service life of the mobile phone, the brightness of the screen of the mobile phone is continuously adjusted for two times on the basis of the brightness of the standard screen of the mobile phone corresponding to the external irradiation light intensity until the brightness of the mobile phone is reduced to 0, namely, the screen of the mobile phone is automatically closed, the time for automatically closing the screen of the mobile phone is set, and the service life of the mobile phone is controlled in a semi-forced mode.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
