Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
First embodiment
Referring to Fig. 1, the first embodiment of the present invention provides a kind of display brightness method of adjustment, and the method is applied to a shifting
Dynamic terminal, the method includes：
Step 101, obtains the current environment illuminance of mobile terminal, determines the first illumination belonging to current environment illuminance
Degree is interval, and wherein, each illuminance interval is to divide, by continuous ambient light illumination, the multiple mutually misaligned intervals obtaining.
Wherein, illuminance is usually said lux degree, represents that the light being subject on shot subject surface unit area leads to
Amount (refers to the sentient radiant power of human eye institute), and illuminance interval is divided by continuous illuminance and obtains, i.e. illuminance
Interval is continuous.
Step 102, according to the interval corresponding relation and automatic current restriction ACL gear between of illuminance set in advance,
Determine the interval corresponding ACL gear of the first illuminance；Under each ACL gear, the light modulation brightness of mobile terminal is bright with display
Curvilinear correlation is become between degree.
Under normal circumstances, light modulation brightness is that the brightness that is conditioned of brightness control function of mobile terminal (is not opening ACL
In the case of, the half point of light modulation brightness is equal to the percentages of theoretical display brightness than numerical value), the brightness of existing mobile terminal
Regulatory function is adjusted by dimming luminance bar, and display brightness is the actual displayed brightness of mobile terminal display screen curtain.Corresponding pass
In system, different illuminance is interval to correspond to different ACL gears.Under each ACL gear, light modulation brightness and display brightness it
Between become different curve linear relationships；Interval according to mobile terminal affiliated illuminance, determine between light modulation brightness and display brightness
Relation, so that according to current light modulation brightness adjustment display brightness.
Preferably, in corresponding relation, there is the light modulation compared with the ACL gear corresponding to the illuminance interval of high ambient light illumination
Brightness and the difference of display brightness, no more than have the tune of the ACL gear corresponding to illuminance interval of relatively low ambient light illumination
Brightness and the difference of display brightness.
Wherein, light modulation brightness and the difference of display brightness, that is, do not open the difference of ACL and the display brightness opened after ACL
(or percentage difference).In corresponding relation, have compared with the ACL gear corresponding to the illuminance interval of high ambient light illumination
Light modulation brightness and the difference of display brightness, no more than have the ACL gear corresponding to illuminance interval of relatively low ambient light illumination
Light modulation brightness and display brightness difference；I.e. for the light modulation brightness of a determination, there is the light compared with high ambient light illumination
Corresponding display brightness in illumination interval, is not less than relatively low display corresponding in the illuminance interval with relatively low ambient light illumination
Brightness.After mobile terminal unlatching ACL, can cause to export GTG reduction, the display brightness in turn resulting in reality will be less than tune
Brightness, produces certain difference, and higher illuminance is interval, difference is more obvious；Open the GTG that ACL causes in order to offset
The reduction of the display brightness of reality changing and causing, in the case that display brightness is less than light modulation brightness, according to ACL gear
Curve linear relationship, suitably supplements display brightness.
On the other hand, due to display brightness corresponding in the illuminance interval with relatively high ambient light illumination, it is not less than relatively
Low corresponding display brightness in the illuminance interval with relatively low ambient light illumination, that is, the corresponding display of higher ACL gear is bright
Degree is more than or equal to the corresponding display brightness of relatively low ACL gear, then when there is multiple ACL gear, for same light modulation
, between the corresponding display brightness of each ACL gear, all there is certain difference in brightness；So under relatively low ambient light illumination,
The high light modulation corresponding display brightness of brightness is less than the display brightness under higher ambient light illumination, then can reach and be limited in environment
In the very low scene of illuminance, open and so that GTG is declined more ACL gear and limit the effect in correct position for the high-high brightness；
In the very high scene of ambient light illumination, open and so that GTG is declined less ACL gear and expand high-high brightness.
And, during light modulation brightness changes, either from high to low, still from low to high, light modulation is interval
Change step by step, ACL gear changes step by step, the difference between each gear also changes step by step, so, in each gear switching point
When, the jump in brightness of generation is relatively low, can effectively slow down vision saltus step.
Step 103, according to the current light modulation brightness of an ACL gear and mobile terminal, adjusts the display of mobile terminal
Brightness.
Wherein, according to current light modulation brightness, determine corresponding display brightness under an ACL gear, bright according to this display
Degree adjustment mobile terminal, combining environmental illuminance, rational display brightness is set.
Preferably, step 103 includes：
Determine first brightness curve corresponding with an ACL gear set in advance；
According to the first brightness curve, determine and the current light modulation corresponding first display brightness value of brightness；
According to the first display brightness value, adjust the display brightness of mobile terminal.
Wherein, the first brightness curve is the corresponding relation between light modulation brightness and display brightness, that is, in different ACL gears
Under, become different curve linear relationships between light modulation brightness and display brightness；According to the first brightness curve and currently dim brightness, really
Fixed first display brightness value and then the display brightness of adjustment mobile terminal.
Alternatively, in step 103, adjustment mobile terminal display brightness the manual regulative mode of user also can be set, when with
When family is adjusted manually, can voluntarily select the light modulation brightness in the first illuminance interval, obtain the display effect that user needs.

L1 corresponding ACL gear is C1, and curve L2 corresponding ACL gear is C2 ..., and curve Ln corresponding ACL gear is Cn, L1～Ln
It is the brightness curve after opening ACL；L0 is the brightness curve after not opening ACL；Wherein, C1, C2 ..., Cn respectively corresponding not
Same illuminance is interval, and the interval height of corresponding illuminance is C1 ＜ C2 ＜ ... ＜ Cn.
After opening ACL, the output GTG of mobile terminal can reduce, and in order to avoid display brightness is undergone mutation, obtains
The illuminance of environment；When the interval corresponding ACL gear of illuminance belonging to when ambient light illumination is C1, show ambient light illumination relatively
Low, the display brightness of needs is relatively low, and therefore corresponding brightness curve is L1, and now light modulation brightness with the difference of display brightness is
(a0-a1), in the case of matching with ambient light illumination, reach preferable power saving effect；And it is maximum in this light modulation interval
Display brightness be L1 peak, less than the peak not opening ACL, effectively limit compared with low irradiance environment
Big brightness.
When the interval corresponding ACL gear of illuminance belonging to when ambient light illumination is Cn, show that ambient light illumination is higher (high
Interval in other light modulations), the display brightness of needs is higher, and therefore corresponding brightness curve is Ln, now light modulation brightness and display
The difference of brightness is (a0-an), it will produce less GTG saltus step；And maximum display brightness is Ln in this light modulation interval
Peak, higher than the peak of other brightness curves, effectively expanded the high-high brightness under high light illumination environment.
In the case that light modulation brightness changes, either from high to low, still from low to high, light modulation interval becomes step by step
Change, in each gear switching point, the luminance difference of generation is relatively low, can effectively slow down vision saltus step.
Preferably, after step 103, the method includes：
When light modulation brightness mobile terminal is detected changes, update the display brightness of mobile terminal.
Wherein, when dimming brightness and changing, brightness curve and display brightness are updated, bright with the display that keeps suitable
Degree.
Alternatively, step 101 includes：
When light modulation brightness mobile terminal is detected reaches default adjustment threshold value, obtain the current environment of mobile terminal
Illuminance.
Wherein, when input GTG reaches light modulation brightness and reaches default adjustment threshold value, ACL is determined according to ambient light illumination
Gear, reduces the output GTG of image, obtains the currently displaying brightness of mobile terminal, determines that the first affiliated illuminance is interval；
And under adjustment threshold value, the GTG saltus step of generation is less, does not start ACL.
As the second example, referring to Fig. 3, wherein, the curve linear relationship between the display brightness shown in Fig. 3 and light modulation brightness
In, curve L1 corresponding ACL gear is C1, and curve L2 corresponding ACL gear is C2 ..., and curve Ln corresponding ACL gear is
Cn, L1～Ln is the brightness curve after opening ACL；Wherein, C1, C2 ..., that Cn corresponds to different illuminance respectively is interval, and
The interval height of corresponding illuminance is C1 ＜ C2 ＜ ... ＜ Cn, and wherein, b point is adjustment threshold value, that is, after b point, according to
Illuminance adjusts display brightness；And before b point, the GTG saltus step due to producing is less, brightness curve need not be adjusted.
