Specific implementation mode
It elaborates with reference to the accompanying drawings of the specification to the specific implementation mode of the embodiment of the present invention.
Embodiment 1：
The adaptive screen luminance adjustment method of the present invention, as shown in Figure 1, including：
S101：User distinguishes self-defined different screen brightness value under different luminous intensities, by the different light intensity
The value of degree and customized different screen brightness value carry out corresponding preservation；
Most common three kinds of luminous intensity environment, i.e. daytime, cloudy day and night are selected, according to daily experience it is found that in light
In the case that intensity is stronger, the screen intensity of required setting is brighter, otherwise will lead to not see screen clearly because reflective.Cause
This, for environment such as above-mentioned daytime, cloudy day and nights, the screen brightness value for making it be satisfied with is respectively set in user.Specific real
Now, the light at any one moment in three kinds of daytime, cloudy day and night environment can be acquired respectively by luminous intensity acquisition module
Intensity value, it is assumed that the light intensity value acquired in above-mentioned three kinds of environment is respectively L1=300lux, L2=75lux and L3=30lux,
And above-mentioned three kinds of environment are directed to, the screen intensity that user is respectively set is B1=Bmax, B2=60%Bmax and B3=Bmin, wherein institute
It is respectively maximum screen brightness value and minimum screen brightness value to state Bmax and Bmin；By light intensity value 300lux, 75lux and
30lux and screen brightness value Bmax, 60%Bmax and Bmin carry out one-to-one correspondence preservation, it is notable that making by oneself herein
Justice operation and preservation operation are interspersed progress, as soon as that is, per self-defined complete screen brightness value, it is self-defined that system preserves once this
Screen brightness value and its corresponding light intensity value.
S102：The standard definition value of common luminous intensity is divided into several sections, what the standard of the luminous intensity defined
