Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those skilled in the art's every other implementation obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of brightness adjusting method, device and terminal.It will be described in detail respectively below.
Embodiment one,
The present embodiment will be described from the angle of brightness regulating apparatus, which specifically can integrate at end
In end, which can be mobile internet device (such as smart phone, tablet computer), intelligent wearable device (such as smartwatch)
Etc. it is all kinds of include display screen electronic equipment.
Referring to Fig. 1, Fig. 1 is the flow diagram for the brightness adjusting method that the embodiment of the present invention one provides, the present embodiment
Brightness adjusting method include:
Step S101 obtains the changing value of terminal tilt angle and locating when the tilt angle of terminal changes
The ambient light intensity of environment.
In embodiments of the present invention, the inclination angle of terminal can be judged according to the current tilt angle of real-time detection terminal
Whether degree changes, specifically, the current tilt angle of a terminal can be obtained with every preset time period, for example, can be with
One timer is set, and setting timer obtains the current tilt angle of a terminal every 2s, wherein the time interval can be with
It is set according to actual needs, for example, can be to be divided into 0.1s, 0.2s etc. between setting time.In order to which terminal electricity can be saved
The time interval, can be set as bigger value, such as 1s, 2s etc., the present invention is not especially limit this by amount.
The history tilt angle of the tilt angle and last time acquisition that will acquire present terminal compares, if they are the same, then it represents that eventually
Current tilt angle is held not change；If it is different, then indicating that the current tilt angle of terminal is changed, i.e. judgement is whole
The step of holding current tilt angle whether to change may include:
The current tilt angle history tilt angle of terminal is obtained, and is judged whether identical；
If so, determining that the tilt angle of terminal does not change；
If not, it is determined that the tilt angle of terminal changes.
Wherein, the changing value of the tilt angle is current tilt angle and the last history tilt angle got
Between difference.
Preferably, in the embodiment of the present invention terminal tilt angle can by acceleration transducer built-in in terminal come
Obtain, due to acceleration transducer in static placement by gravity, have the acceleration of gravity of 1g, utilize this
Property can calculate the inclination angle of terminal by component of the measurement acceleration of gravity on each axis of acceleration transducer
Degree；For example, the weight component in its X-axis and Y-axis is measured using 2 axis gravity accelerometers, to measure on X-Y axial plane
Tilt angle, but in practical application, terminal is when space tilts, it is difficult to ensure that inclination is completely in X-Y axial plane
On, limitation can be had in this way by being measured using 2 axle acceleration sensors, and measurement result may be inaccurate, it is therefore preferable that
, 3 axle acceleration sensors can be used in the terminal in the embodiment of the present invention, and 3 axle acceleration sensors can measure X-axis, Y-axis
With the weight component above Z axis, to can be calculated terminal in the tilt angle in space.
When the tilt angle for determining terminal changes, the ambient light intensity of current environment can also be obtained, than
Such as, an ambient light sensor is preset in the terminal, which can obtain terminal local environment
Current light intensity, wherein the environment light can be outdoor daylight, indoor light etc..
Step S102 obtains the corresponding luminous intensity compensated information of above-mentioned angle change value.
Specifically, the embodiment of the present invention can pre-establish angle change value and the mapping of luminous intensity compensated information is closed
Assembly is closed, for example, tentative standard light source is incident vertically downward, mobile phone is lain in a horizontal plane under light source, records the light of mobile phone at this time
Intensity values, then, due to the reduction of ambient light sensor light area, environmental light intensity value will when mobile phone turns about the X axis
Reduce.It counts under differing tilt angles, the intensity of environment light.It calculates under different angle, the attenuation ratio of ambient light intensity, simultaneously
Also just having obtained should be multiplied by the great gain just available influence for reducing arrisdefect degree to light intensity value.
Certainly, in practical application, the inclined angle of terminal may be important in the X-axis, Y-axis and Z axis in space,
Therefore the mapping relations of the angle change value and luminous intensity compensated information on X-axis, Y-axis and Z axis can be established respectively,
When terminal inclination, the tilt angle may only change on an axis, such as X-axis, only be needed at this time according in X
Angle change value luminous intensity offset corresponding with the acquisition of the mapping relations of luminous intensity compensated information on axis；When terminal
For tilt angle when important in the X-axis, Y-axis and Z axis in space, then the tilt angle institute for obtaining face on each axle respectively is right
The luminous intensity offset answered, COMPREHENSIVE CALCULATING go out final luminous intensity offset, in the mapping relations set, angle change

The corresponding relationship of information, for example, the corresponding luminous intensity of range that tilt angle is 5 ° -10 ° is 500cd, tilt angle is
10 ° -15 ° of the corresponding luminous intensity of range is 1000cd etc., can first be determined according to angle change value close in mapping at this time
Locating range in assembly conjunction is obtaining the corresponding luminous intensity compensated information of the range of tilt angles.
Step S103 compensates ambient light intensity according to above-mentioned luminous intensity compensated information.
It should be noted that the luminous intensity compensated information be divided into it is positive and negative, because of the feelings constant in current environment luminous intensity
Under condition, the change of terminal tilt angle will have a direct impact on the luminous intensity of ambient light sensor light well, so the value meeting of sensor
It changes, and point that this variation is positive and negative as the variation of terminal tilt angle also has, for example terminal tilt angle is by 0 °
(the horizontal positioned angle of angle, that is, mobile phone that mobile phone perpendicular light source is placed) becomes 20 °, the light intensity of ambient light sensor light well
Degree will be lower, this Light intensity compensated information is positive；And when terminal tilt angle becomes 0 ° from 20 °, ambient light sensor into
The luminous intensity of unthreaded hole will be got higher, this Light intensity compensated information is just negative.
Step S104 is adjusted according to brightness of display screen of the compensated ambient light intensity to the terminal.
Optionally, the present embodiment can establish the default corresponding relationship of ambient light intensity and brightness of display screen in advance, so
Above-mentioned the step of being adjusted according to brightness of display screen of the compensated ambient light intensity to the terminal, can specifically include:
Mesh is determined in the default corresponding relationship of ambient light intensity and brightness of display screen according to compensated ambient light intensity
Mark brightness value；

From the foregoing, it will be observed that the embodiment of the present invention is used when the tilt angle of terminal changes, the change of tilt angle is obtained
The ambient light intensity of change value and current environment obtains angle change and is worth corresponding luminous intensity compensated information, according to the light
Intensity compensation information compensates ambient light intensity, is carried out according to brightness of display screen of the compensated ambient light intensity to terminal
It adjusts；This programme can compensate ambient light intensity when the current tilt angle of terminal changes, relative to existing terminal
In brightness adjustment approach, when can change in terminal tilt angle and brightness of display screen is caused to change, to brightness
It is compensated accordingly, improves the accuracy of brightness regulation, user is facilitated to adjust brightness of display screen, promote user experience.

It sets timer and obtains the current tilt angle (can use the acceleration transducer in terminal) of a terminal every 2s, if obtaining
Tilt angle and the last tilt angle got it is not identical, then judge that the tilt angle of terminal changes, and it becomes
Change value is the difference between current tilt angle and the last tilt angle got；And its ambient light intensity can then lead to
The ambient light sensor measurement crossed in terminal obtains.

Step S204 keeps current brightness of display screen.
When even angle change value is not more than preset threshold, the angle change of terminal is little, so need not be to it
Brightness of display screen is adjusted, then the brightness for keeping display screen current is constant.
Step S205 compensates ambient light intensity according to light compensated information.
Step S206 obtains the light intensity difference between compensated ambient light intensity and history luminous intensity.
Wherein, above-mentioned history light intensity difference is the ambient light intensity before compensating, since compensated ambient light intensity is compared
Could possibly be higher than in history luminous intensity may also be lower than, so the light between above-mentioned compensated ambient light intensity and history luminous intensity
Intensity difference is also required to distinguish positive and negative.
Step S207 is adjusted according to brightness of display screen of the luminous intensity difference to terminal.
It is also little to the amplitude of accommodation of terminal display screen brightness accordingly in view of when luminous intensity difference is smaller, it can be with
It is ignored, optionally, the range of a luminous intensity difference can be preset in the present embodiment, then first determine whether the light
