Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following exemplary is implemented
Embodiment described in example does not represent all embodiments consistent with the present invention.On the contrary, they are only and such as institute
The example of the consistent apparatus and method of some aspects of the described, present invention in attached claims.
Fig. 1 is a kind of screen backlight luminance regulating method based on light sensor according to an exemplary embodiment
Flow chart, may comprise steps of as shown in figure 1, being somebody's turn to do the screen backlight luminance regulating method based on light sensor.
In step s 110, the light sensation readings of light sensor is read.
Light sensor is the light sensation equipment for detecting local environment brightness.
It is understood that the detection of environmental light brightness is carried out by light sensor, and then according to light sensor
Light sensation readings automatically adjusts to screen backlight brightness.
The light sensation readings of light sensor is the value of electrical signals that the environmental light brightness detected is obtained after conversion, and light is passed
The light sensation readings of sensor is by light sensation characteristic curve and specific environment bright angle value maps mutually, so that the light sensation of light sensor
Readings characterizes the environment bright angle value obtained by light sensor detection.Therefore, the light sensation readings of light sensor will be with ring
The change of border brightness and change.
During applied to scenes such as screen backlight brightness regulations, the light sensor in terminal is run, to feel
The brightness of environment where knowing, and then export corresponding light sensation readings.
Wherein it should be noted that the reason such as change due to light sensor local environment, environmental light brightness will occur
Certain change；Further, since the error and the reason such as mobile of position of light sensor itself, in a same environment,
Its light sensation readings detected is not to maintain invariable yet.
According to the difference of environmental light brightness, there is certain light sensation readings scope in the light sensation readings of light sensor.
Light sensation readings scope be in light sensor light sensation readings can interval.
It is as shown in the table in a specific exemplary embodiment, in different scenes, light sensation readings and different scenes
In environmental light brightness it is corresponding.
In the step s 120, when the light sensation readings for detecting reading is to switch to adjacent buffering area from scene area, control
System keeps screen backlight brightness to be still the corresponding brightness value in scene area.
Buffering area is the transitional region between the light sensation readings scope midfield scenic spot of light sensation readings.
In a specific exemplary embodiment, adjacent Liang Ge scenes area D1, D2 light sensation readings scope be respectively [0,
18)、[20,38).For example, will [18,20) it is set to the buffering area B1 between scene area D1 and scene area D2.
When light sensation readings is to switch to adjacent buffering area from scene area, show that the change of light sensation readings is smaller, and
Fluctuated in smaller range between Liang Ge scenes area, therefore readings buffered need to be carried out, shielded after readings buffered
The regulation of curtain backlight illumination；When light sensation readings is not to switch to adjacent buffering area from scene area, then show light sensation readings
Change greatly, therefore readings buffered need not be carried out, directly screen backlight brightness is adjusted according to the light sensation readings.
As previously described, when light sensation readings changes to adjacent buffering area from a scene area, light sensation readings is shown
Change is smaller, and is fluctuated in the smaller range between Liang Ge scenes area.
Therefore now by screen backlight brightness regulation, the interval corresponding backlight of buffering at the light sensation readings is not bright
Degree, the residing corresponding backlight illumination in scene area before being maintained as the change of light sensation readings, so as to avoid causing screen back light
The frequent switching of degree.
For example, Liang Ge scenes area D1, D2 light sensation readings scope be respectively [0,18), [20,38), scene area D1 and D2 it
Between buffering area B1 for light sensation readings scope [18,20).Current light sensation readings R1 is 19, in buffering area B1, and a upper light
It is 23 to feel readings R2, adjacent buffering area is switched to from scene area in scene area D2, i.e. light sensation readings, so as to show adjacent two
The excursion of individual light sensation readings is smaller, therefore the scene area D2 according to residing for upper light sensation readings R2 enters to screen backlight brightness
Row regulation, continues to keep screen backlight brightness to be the corresponding brightness values of scene area D2.
Using method as described above, during being automatically adjusted to screen backlight brightness, it is in light sensation readings
When changing to adjacent buffering area from a scene area, readings buffered is carried out to light sensation readings, control keeps screen backlight
Brightness is still the corresponding brightness value in scene area, it is to avoid because light sensation readings is fluctuated in smaller range between two opposite field scenic spots
When and cause screen backlight brightness do not stop change, reduce screen backlight flicker.
Fig. 2 is another screen backlight brightness adjustment side based on light sensor for correspondingly being implemented to exemplify according to Fig. 1
Method, as shown in Fig. 2 before the step S110 during Fig. 1 corresponds to embodiment, being somebody's turn to do the screen backlight brightness based on light sensor and adjusting
Adjusting method can also comprise the following steps.
In step S210, the light sensation readings scope of light sensor is alternately divided into multiple buffering area and scene area.
As previously described, light sensation readings scope be in light sensor light sensation readings can interval.
Light sensation readings scope is related to environmental light brightness.In the process automatically adjusted to screen backlight brightness
In, the detection for carrying out environmental light brightness to local environment by light sensor obtains light sensation readings, and light sensation readings and environment
Be present certain mapping relations in brightness, thus according to light sensation readings to regulation screen backlight brightness, realize to screen back light
Degree automatically adjusts.
And the reason such as unordered change, the detection error of light sensor due to environmental light brightness, the light of light sensor
Sense readings is fluctuated always.Now, the backlight illumination of screen is adjusted if being based entirely on light sensation readings, screen will be made
Backlight illumination is ceaselessly changing, and that causes screen does not stop flicker, drastically influence the vision health and mood of user.
Therefore, the light sensation readings scope of light sensation readings is alternately divided at least one buffering area and scene area, when light sensation is read
When value changes in a certain scene area, do not change the backlight illumination of screen, so can be according to the back of the body of the environmental light brightness to screen
Brightness automatically adjusts, be avoided that again because light sensation readings do not stop changing caused by screen backlight brightness frequent switching, subtract
The backlight flicker of few screen.
For example, Liang Ge scenes area D1, D2 light sensation readings scope be respectively [0,18), [20,38), scene area D1, D2 couple
The backlight illumination answered is divided into L1, L2.In the range of a period of time, when light sensation readings [20,38) between do not stop fluctuation when, still protect
Hold screen backlight illumination be L2, it is to avoid because the relatively minor swing of light sensation readings and caused by screen backlight illumination frequent switching.
Buffering area be light sensation readings light sensation readings scope in transitional region between different scenes area.
The light sensation readings scope of light sensation readings is divided into buffering area and scene area, the interval for dividing buffering area and scene area is big
Hour, can be after a scene area is chosen, according to the light sensation readings size in the scene area, according to certain percentage,
Buffering area is chosen beyond the border in the scene area, then chooses other successively in light sensation readings scope further according to same method
Scene area and buffering area；Can also, according to default light sensation readings size, after a scene area is chosen, be read according to light sensation
Value size chooses buffering area beyond the border in the scene area, then further according to same method in light sensation readings scope successively
Choose other scene areas and buffering area；The interval size in buffering area and scene area can also be divided by other means, herein
Without limiting.
For example, in the light sensation readings scope of light sensor, choose scene area D1 light sensation readings scope for [0,18),
By default 10% ratio, choose [18,20) it is buffering area B1；In another example, in the light sensation readings scope of light sensor,
Choose scene area D1 light sensation readings scope for [0,18), the light sensation readings range size in pre-set buffer area is 3, choose [18,
21) it is buffering area B1.
In step S220, the correspondence of brightness value is carried out to scene area.
As previously described, with environmental light brightness there are certain mapping relations in light sensation readings.Thus according to different scenes area
Corresponding light sensation readings scope, the environmental light brightness that each scene area is characterized is each different, therefore according to different scenes area pair
Light sensation readings size in the light sensation readings scope answered, the correspondence of brightness value is carried out to each scene area.
For example, 3 scene areas D1, D2, D3 light sensation readings scope be respectively [0,18), [20,38), [40,58), scene
The corresponding brightness value of area D1, D2, D3 is respectively 20,40,60.
In step S230, for each buffering area, distinguish corresponding according to the Liang Ge scene area adjacent with buffering area
Brightness value, chooses a brightness value corresponding with buffering area.
As previously described, buffering area is the transition region between Liang Ge scenes area.And the corresponding brightness value in each scene area is mutual
Differ, thus the corresponding brightness value of buffering area can be any one corresponding brightness value in scene area adjacent thereto.
For example, by pre-setting, by less brightness in the corresponding brightness value in Liang Ge scenes area adjacent with buffering area
Value is used as the corresponding brightness value of the buffering area.
Using method as described above, by the way that the light sensation readings scope of light sensor alternately is divided into multiple bufferings in advance
Area and scene area, by buffering area to light sensation readings carry out buffered, it is to avoid because light sensation readings two opposite field scenic spots it
Between fluctuate when and cause screen backlight illumination do not stop change, reduce screen backlight flicker.
Fig. 3 is another screen backlight brightness adjustment side based on light sensor for correspondingly being implemented to exemplify according to Fig. 2
Method, as shown in figure 3, being somebody's turn to do the screen backlight luminance regulating method based on light sensor can also comprise the following steps.
In step S150, light sensation readings be in buffering area when, if the light sensation readings for detecting reading be not from
The adjacent scene area of buffering area switches to buffering area, it is determined that the corresponding brightness value of buffering area residing for light sensation readings.
When light sensation readings is to switch to buffering area from non-adjacent scene area or buffering area, then show the change of light sensation readings
Change larger.Therefore readings buffered need not be now carried out, the directly buffering area according to residing for the light sensation readings determines corresponding
Brightness value, and then screen backlight brightness is adjusted according to the brightness value.
For example, scene area D1, D2, D3 light sensation readings scope be respectively [0,18), [20,38), [40,58), scene area
Between D1, D2 buffering area B1 light sensation readings scope be respectively [18,20), between scene area D2, D3 buffering area B2 light sensation read
[38,40) value scope is respectively.Light sensation readings R1 is 19, in buffering area B1, and light sensation readings R1 upper light sensation readings R2
It is not to switch to buffering area B2 from the region adjacent with buffering area B2 in buffering area B2, i.e. light sensation readings for 39, therefore,
The corresponding brightness value Ls 1 of buffering area B1 residing for light sensation readings R1 are directly obtained, and then according to brightness value L 1 to screen backlight brightness
It is adjusted.
It is the corresponding brightness value of buffering area residing for light sensation readings by screen backlight brightness regulation in step S160.
Using method as described above, during being automatically adjusted to screen backlight brightness, when light sensation readings is
When switching to buffering area from non-adjacent scene area or buffering area, the buffering area directly according to residing for current light sensation readings is corresponding
Brightness value is adjusted to screen backlight brightness, improves the efficiency of screen backlight brightness regulation.
Optionally, correspondingly implement the screen backlight luminance regulating method based on light sensor exemplified according to Fig. 1, walk
After rapid S110, being somebody's turn to do the screen backlight luminance regulating method based on light sensor can also comprise the following steps.
In step S310, when the light sensation readings of reading is in scene area, screen backlight brightness is set to light sensation and read
The residing corresponding brightness value in scene area of value.
It is understood that because the light sensation readings scope of light sensation readings includes buffering area and scene area, therefore, light sensation is read
Value is likely to be at buffering area, it is also possible in scene area.
When light sensation readings be in scene area when, due to scene area only one of which brightness value correspondence, therefore no matter screen work as
Which brightness value preceding backlight illumination is, the backlight illumination of screen is set into the corresponding brightness value in scene area.
For example, light sensation readings is in scene area D2, D2 corresponding brightness values in scene area are brightness value L 2.It is current when screen
When backlight illumination is brightness value D2, then keep the backlight illumination of screen constant；When the current backlight brightness of screen is brightness value D1
When, then the backlight illumination of screen is changed into D2 from brightness value D1.
Using method as described above, when light sensation readings is in scene area, no matter which the backlight illumination before screen is
One brightness value, is directly set to the corresponding brightness value in scene area residing for the light sensation readings, so as to carry by screen backlight brightness
The high efficiency of screen backlight brightness regulation.
Fig. 4 is step in the screen backlight luminance regulating method based on light sensor according to above-described embodiment
S310 detailed description, as shown in figure 4, should be based on the step S310 in the screen backlight luminance regulating method of light sensor also
It may comprise steps of.
In step S311, when the light sensation readings for detecting reading is to switch to adjacent scene area from buffering area, obtain
Take current screen backlight brightness.
As previously described, when light sensation readings is in buffering area, screen backlight brightness is two fields adjacent with the buffering area
Distinguish one in corresponding brightness value in scenic spot.
Therefore, light sensation readings is in scene area, when a upper light sensation readings for light sensation readings is in adjacent with the scene area
Buffering area when, screen backlight brightness may be the corresponding brightness value in scene area, it is also possible to be adjacent with the buffering area another
The corresponding brightness value in one scene area.
For example, being buffering area B1 between scene area D1 and scene area D1, light sensation readings R1 is in scene area D1, light sensation readings
When R1 upper light sensation readings R2 is in buffering area B1, screen backlight brightness may be the corresponding brightness value Ls 1 of scene area D1,
May also be the corresponding brightness value Ls 2 of scene area D2.
Whether in step S313, it is the corresponding brightness value in scene area residing for light sensation readings to judge screen backlight brightness,
If it has, then performing step S314, if NO (N), then step S315 is performed.
When the corresponding brightness value in scene area of the screen backlight brightness residing for light sensation readings, then screen backlight brightness is kept
It is constant；, then must be to screen back light when the corresponding brightness value in the scene area residing for screen backlight brightness is not light sensation readings
Degree is adjusted, i.e. by the corresponding brightness value in scene area residing for screen backlight brightness regulation to light sensation readings.
In step S314, keep screen backlight brightness constant.
It is the corresponding brightness value in scene area by screen backlight brightness regulation in step S315.
Using method as described above, when the light sensation readings for detecting reading is that adjacent scene area is switched to from buffering area
When, then judge whether screen backlight brightness is the corresponding brightness value in scene area, it is scene area correspondence in screen backlight brightness
Brightness value when, then keep screen backlight brightness constant, when screen backlight brightness is not the corresponding brightness value in the scene area, then
It is the corresponding brightness value in scene area by screen backlight brightness regulation, so as to carry out screen back according to current screen backlight brightness
The regulation of brightness.
