Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
As shown in Fig. 2, provided in an embodiment of the present invention is a kind of method of adjusting backlight luminance, following step is specifically included
It is rapid:
Step 200: terminal is determined by the sensor on the face where the currently used screen of user occurs brightness fluctuation,
And brightness fluctuation is not occurred by the sensor determination on other faces other than the currently used screen of user, wherein the brightness
Fluctuation is more than first threshold for the difference of the interior brightness maxima determined by sensor of the first duration of setting and brightness minimum value；
Step 201: the terminal is adjusted the backlight illumination of the screen and keeps the brightness after adjusting.
Through the above scheme, the brightness that terminal is detected by the sensor on the face where the currently used screen of user
Brightness fluctuation occurs for value, and the brightness value detected by the sensor in the other faces other than the currently used screen of user is not
Brightness fluctuation occurs, then terminal determines the currently scene for environment photo-labile, and the backlight illumination of the screen is adjusted
And keep the brightness after adjusting.The terminal of that embodiment of the invention is no longer only carried out by the brightness value that the sensor of unilateral screen determines
Backlight illumination is adjusted, but by be located at the screen that uses of user sensor and the screen currently used except user on the whole
The brightness value that sensor in other faces other than side determines carries out backlight illumination adjusting, is determined by the sensor of above-mentioned two sides
Brightness value can determine more complicated light field scape, such as the scene of environment photo-labile, and environment can be in determining
When photo-labile, keep adjust after backlight illumination, avoid the backlight illumination of terminal with the alternate environment light of extraneous light and shade and
There is flickering phenomenon, to reduce the influence to display effect.
Sensor in the embodiment of the present invention for determining brightness value is photosensitive sensors, wherein is currently made by user
Sensor other than screen on other faces determines the first brightness value, by the face where the currently used screen of user
Sensor determine the second brightness value.
In embodiments of the present invention, there are many kinds of the case where terminal determine brightness value by photosensitive sensors, is set forth below
It is several:
Terminal situation one, terminal have a screen；
As shown in figs.3 a and 3b be the terminal schematic diagram with unilateral screen, wherein Fig. 3 A be the terminal of unilateral screen just
Face schematic diagram, Fig. 3 B are the terminal schematic rear view of unilateral screen.
Current most of terminals only have unilateral screen, i.e., light sensation sensing is only equipped on the face where the screen used
Device, for the terminal of unilateral screen, the embodiment of the present invention passes through other other than the face where the currently used screen of terminal
Photosensitive sensors are installed, to detect the brightness value (the first brightness value i.e. in the present invention) of environment light on face.
It gives some instances below to photosensitive sensors position:
Example one: the surrounding that photosensitive sensors are connected with currently used screen at the terminal；
As shown in figure 4, a kind of position view for installing photosensitive sensors provided in an embodiment of the present invention.
For example terminal is mobile phone, indicates that photosensitive sensors are installed at the place any one all around of thickness in mobile phone.
Example two: photosensitive sensors are located on the opposite face of active user uses in terminal screen；
As shown in figure 5, the position view of another kind photosensitive sensors provided in an embodiment of the present invention.
For example terminal is mobile phone, photosensitive sensors can be located at the back side (i.e. the not side of screen) of mobile phone.
It should be noted that above-mentioned installation site is only for example, photosensitive sensors should not influence user in the position of terminal
It uses, and is not easy to be user-operably what gesture was blocked, specific location can combine making for user according to the actual size of terminal
With habit, installed according to the better position that actual measurement obtains.
When determining the first brightness value and the second brightness value, brightness that terminal can be detected by a photosensitive sensors
Value is determined, and can also be determined by the brightness value that multiple photosensitive sensors detect.
The quantity of photosensitive sensors is illustrated below:
Quantity one: brightness value is determined by a photosensitive sensors；
Incorporated by reference to Fig. 4 and Fig. 5, a photosensitive sensors of the terminal on the face where the screen that user uses determine second
Brightness value determines the first brightness value by any one photosensitive sensors on Fig. 4 or position shown in fig. 5.
Quantity two: brightness value is determined by multiple photosensitive sensors；
As shown in fig. 6, there is a photosensitive sensors A on the opposite face for the screen that active user uses, in screen
On face where surrounding have photosensitive sensors B and photosensitive sensors C, terminal obtained respectively when determining the first brightness value this three
Three brightness values progress operation is determined the first brightness value by three brightness values that a photosensitive sensors detect, terminal, than
Such as calculation process can be averaged or is maximized to three brightness values.
Multiple photosensitive sensors can also be installed on the face where the screen that user uses, for determining the second brightness
Value, specific to execute the step of step may refer to above-mentioned the first brightness value of determination, details are not described herein again.
Terminal situation two, there are two screens for terminal tool；
If terminal is mobile phone, as shown in figs. 7 a-b, for the schematic diagram of the terminal with double-sided screen, wherein Fig. 7 A is
The terminal front side schematic diagram of double-sided screen, Fig. 7 B are the terminal schematic rear view of double-sided screen.
For having the terminal there are two screen, photosensitive sensors, terminal are all had on the face where general two screens
The first brightness value and the second brightness value can be determined by the two photosensitive sensors；Also it may refer to above-mentioned as single in situation one
The mode of the terminal of side screen installs photosensitive sensors to determine the first brightness value and the second brightness value.
In conjunction with above-mentioned light field scape 2, terminal passes through the biography in the other faces other than the face where the currently used screen of user
Sensor determines the first brightness value, determines the second brightness value by the sensor on the face where the currently used screen of user, if
Terminal determines that brightness fluctuation occurs for the second brightness, and brightness fluctuation does not occur for the first brightness, it is determined that is currently at environment light not
Stable light field scape.
Wherein, the definition of brightness fluctuation is to set the brightness maxima determined in the first duration by sensor and brightness
The difference of minimum value is more than first threshold.
As shown in figure 8, the wave of the second brightness value of the generation brightness fluctuation that terminal provided in an embodiment of the present invention detects
Shape schematic diagram.
If setting the first duration t1 as 5s (second, second), first threshold is 20lux (lux).Wherein, lux is
Illuminate unit.Terminal detects that the difference of the second brightness maxima and the second brightness minimum value is more than that 20lux or terminal are true in 5s
The difference of fixed second brightness maxima and the second brightness minimum value is more than the time interval of 20lux less than 5s, then terminal determines the
Brightness fluctuation occurs for two brightness.
Wherein, during brightness minimum value when generation brightness fluctuation and the time interval of brightness maxima are brightness fluctuation.
If terminal determines that brightness fluctuation occurs for the second brightness, and brightness fluctuation does not occur for the first brightness, then terminal determination is worked as
The preceding light field scape in environment photo-labile, terminal determine that the backlight of the screen used active user is bright according to the first brightness value
The regulated value of degree.
Since the first brightness value is not fixed and invariable, when determining regulated value by the first brightness value, terminal
It can be during the brightness fluctuation of the second brightness or in the adjacent preset time range during brightness fluctuation, according to the first brightness
It is worth curve, selects a brightness value, as the first determining brightness value, for determines the backlight of the screen used active user
The regulated value of brightness.
Below for during the second brightness fluctuation, the case where being likely to occur to the first brightness, is illustrated:
Brightness fluctuation and brightness stability do not occur for one: the first brightness of brightness case；
As shown in figure 9, during being the second brightness fluctuation provided in an embodiment of the present invention the case where first brightness stability.
Wherein, the definition of brightness stability is to set in the first duration, the brightness maxima and bright determined by sensor
The difference for spending minimum value is no more than second threshold, wherein second threshold is less than first threshold.
It is assumed that setting is at the first time t1, in the time, second threshold 5lux, such as terminal determine the first brightness in 5s
The difference of maximum value and the first brightness minimum value is no more than 5lux or terminal determines brightness maxima and the smallest difference of brightness is
Period when 5lux is more than 10s.
As shown in figure 9, during the second brightness fluctuation first brightness maxima of (t2) and the first brightness minimum value difference
Value is less than second threshold, then terminal determines the first brightness stability during the second brightness fluctuation.
Brightness fluctuation does not occur for two: the first brightness of brightness case and brightness is unstable；
As shown in Figure 10, the situation unstable for the first brightness during the second brightness fluctuation provided in an embodiment of the present invention.
The difference of first brightness maxima and the first brightness minimum value is more than the time of second threshold to be less than t1, then terminal is true
During being scheduled on the second brightness fluctuation, the first brightness is unstable.
The possible situation of first brightness during above situation is the second brightness fluctuation, below to according to the second brightness fluctuation phase
Between how to determine for determining that explanation is introduced in the first brightness value of backlight illumination regulated value:
Method of determination one: the average value of the first brightness is as the first determining brightness value during using the second brightness fluctuation.
Terminal is and bright according to determining first using the average value of the first brightness in the t2 time as the first determining brightness value
Angle value determines regulated value when backlight illumination is adjusted.
Method of determination two: any one brightness value is as the first determining brightness value during using the second brightness fluctuation.
Terminal selects any one brightness value in the t2 period in the first brightness value curve as the first fixed brightness value,
And regulated value when backlight illumination is adjusted is determined according to the first determining brightness value.
Further, terminal can choose first brightness value of first brightness maxima as determination in the t2 period, and root
Regulated value when backlight illumination being adjusted to determine according to the first determining brightness maxima.
Wherein, regulated value when terminal is adjusted backlight illumination to determine according to the first brightness maxima, Neng Goubao
Demonstrate,prove user can in brighter environment light normal use, therefore can be by the first brightness maxima preferably.
Method of determination three: using the highest brightness value of probability of occurrence as the first determining brightness value.
Terminal can determine that probability distribution curve selects highest first brightness value of probability of occurrence according to the first brightness value, will
The highest value of probability of occurrence is as the first determining brightness value during second brightness fluctuation, and terminal is according to the first determining brightness value
Regulated value when backlight illumination being adjusted to determine.
After the first brightness value during terminal determines the second brightness fluctuation, by following condition determine to backlight illumination into
Regulated value when row is adjusted:
As shown in figure 11, below according to method of determination one, select the first average brightness as the first determining brightness value
For, explanation, which is introduced, in the process of regulated value is determined according to the first determining brightness value to terminal:
Wherein, V1Indicate the first brightness value, V2Indicate that the second brightness value, threhold2 indicate second threshold, threhold3
Indicate third threshold value, V2Max indicates the second brightness maxima, V2Min indicates the second brightness minimum value.
Condition one: V1< threhold2；
If terminal determines the first brightness value V1When less than second threshold threhold2, i.e., it is darker to be in environment light for terminal
Light field scape, then terminal will be with the second brightness minimum value V2The difference of min is no more than one of them in third threshold value threhold3
Value is used as regulated value.
For example, the first brightness value V1It is 40lux, the second brightness minimum value V for 20lux, second threshold threhold22min
It is 2lux for 30lux, third threshold value threhold3.
It is calculated according to above-mentioned: V1< threhold2, the regulated value are and the second brightness minimum value V2The difference of min is not
More than any one value in the range of 2lux, the range of choice of the corresponding regulated value is 30lux ± 2lux, i.e. regulated value
Value range be 28lux -32lux.
Condition two: V1≥threhold2&|V2min-V1|≥|V2max-V1|；
The first brightness value V that terminal determines1It is when not less than second threshold threhold2, i.e., finally brighter in environment light
Scene；And the second brightness minimum value V2Min and the first brightness value V1Difference be not less than the second brightness maxima V2Max and
One brightness value V1Difference, then the terminal is by the second brightness maxima V2Max (i.e. with the first brightness value V1Difference smaller) make
For regulated value, selected in the first brightness minimum value and the first brightness maxima immediate bright as backlight with the first brightness value
The regulated value of degree.
It should be noted that as the second brightness minimum value V2Min and the first brightness value V1Difference and the second brightness maxima
V2Max and the first brightness value V1Difference it is equal when, by the second brightness maxima V2maxAs regulated value, if can guarantee user
When in the brighter situation of environment light can normal use, therefore by the second brightness maxima V2Max is bright as backlight is carried out
Regulated value when degree is adjusted.
Condition three: V1≥threhold2&|V2min-V1| < | V2max-V1|；
The first brightness value V that terminal determines1It is when not less than second threshold threhold2, i.e., finally brighter in environment light
Scene, and the second brightness minimum value V2Min and the first brightness value V1Difference less than the second brightness maxima V2Max with
The first brightness value V1Difference, then the terminal is by the second brightness minimum value V2Min is as regulated value.
In the embodiment of the present invention, the second brightness minimum value V is determined2Min and the second brightness maxima V2The mode of max has more
Kind, it is exemplified below:
Mode one: maximum value and minimum value during fluctuation.
Terminal determines the second brightness minimum value and the second brightness maxima according to the brightness value during the second brightness fluctuation.
For example, during the second brightness fluctuation, the minimum point of the second brightness value curve is 5lux, highest point 40lux,
Then terminal determines that the second brightness minimum value is 5lux, and the second brightness maxima is 40lux.
Mode two: the first brightness curve corresponding during the second brightness fluctuation is divided into several sections, to each section
The brightness minimum value averaged inside obtained is as the second brightness minimum value, correspondingly, the brightness to obtaining in each section
