Balance parameters, so as to obtain the better photo of effect.RGB sensors are typically mounted on close to the position of rear camera,
The RGB sensors can also calculate light intensity according to the parameter of RGB three primary colours detected by special algorithm.Namely
It says, RGB sensors can also detect the light intensity in environment.
In the embodiment of the present invention, light sensor and RGB sensors can detect the light intensity in environment in real time.Cause
This, at the end of mobile terminal detects user's communication, can obtain light sensor and detect that the first light of current environment is strong
Degree, i.e., the first light intensity that light sensor detects at the end of user's communication.Meanwhile mobile terminal can be from pre-recorded light
The second light intensity that user detects before the call is obtained in the history light intensity that line sensor detects, so as to true
Determine first amplitude of variation of first light intensity relative to the second light intensity.
Under normal conditions, user one layer of greasy dirt can occur after having made a call on mobile phone screen, if the greasy dirt is stained on
Near light sensor, the accuracy of the light intensity of light sensor detection may will be influenced.Therefore, mobile phone can obtain
Take the first amplitude of variation of light intensity that light sensor detects respectively after user has made a call and before making a phone call.
102nd, mobile terminal determines RGB sensors detect at the end of the mobile terminal call light intensity relative to this
Second amplitude of variation of the light intensity that RGB sensors detect before mobile terminal call.
In the embodiment of the present invention, mobile terminal obtain light sensor in user's communication at the end of relative to call before
While first amplitude of variation of light intensity, the light of user that RGB sensors detect in end of conversation can be also obtained
Second amplitude of variation of light intensity of the intensity relative to user before the call.Therefore, step 102 can be with step 101 simultaneously
It performs, the embodiment of the present invention does not limit.
It should be noted that under normal circumstances, work as although light sensor and RGB sensors are detected in synchronization
The light intensity of preceding environment might not be equal, but light sensor and RGB sensors are in each self-test of identical two moment
The amplitude of variation difference of the light intensity arrived should be smaller.But if when light sensor is blocked, such as it is stained with last layer oil

Specifically, mobile terminal is by judging it is default whether the difference of the first amplitude of variation and the second amplitude of variation is more than
Threshold value judges whether the light sensor is blocked.Wherein, which is mainly as in nearly one week in certain time period
The average value of the amplitude of variation difference for the light intensity at identical two moment that two sensors detect, is mainly detected not
The amplitude of variation of light intensity when being conversed, the predetermined threshold value could be provided as very little, and such as 5cd, (wherein, cd, that is, candela is
Weigh the unit of light intensity size), occurrence needs frequent according to the sensitivity of two light sensors and mobile terminal
The light source of local environment such as point light source or area source etc. determine that the embodiment of the present invention does not limit.
Therefore, if mobile terminal judges that the difference of the first amplitude of variation and the second amplitude of variation is more than predetermined threshold value,
The first light intensity will be so modified using the difference, obtain target light intensity.If mobile terminal is judged
The difference of first amplitude of variation and the second amplitude of variation is less than or equal to predetermined threshold value, then indicates that light sensor may be simultaneously
It not being blocked, i.e., after user's communication, greasy dirt of the user on the face or on hair is not attached near light sensor, from
And show that the light intensity that light sensor detects is more accurate, then mobile terminal can be examined according to the light sensor
It measures the first light intensity and adjusts screen intensity.
104th, mobile terminal is modified first light intensity using the difference, obtains target light intensity.
In the embodiment of the present invention, when mobile terminal judges that the difference of the first amplitude of variation and the second amplitude of variation is more than in advance
If during threshold value, indicating that light sensor is blocked, i.e., after user's communication, greasy dirt of the user on the face or on hair attaches
Near light sensor, then the light intensity that light sensor detects is inaccurate, so mobile terminal is needed to this
The light intensity that light sensor detects is modified.Therefore, which can use the difference to light level
The first light intensity that device detects is modified, and obtains target light intensity.
It should be noted that mobile terminal just carries out the first light intensity that light sensor detects using the difference
Modified major way is that the first light intensity is obtained target light intensity plus the difference.It can subtract in this way
The attenuation of the small light intensity detected due to light sensor caused by greasy dirt, so that mobile terminal is according to light intensity
When adjusting screen intensity, the adjusting of screen intensity is more in line with the practical light intensity of environment, that is to say, that can improve screen
The accuracy of brightness regulation, so as to promote user experience.
Optionally, mobile terminal can also be according to the mathematic interpolation light level of the first amplitude of variation and the second amplitude of variation
Device detects the attenuation ratio of light intensity after greasy dirt is stained with, so as to be detected by the attenuation ratio to light sensor
To the first light intensity be modified, obtain target light intensity.
105th, mobile terminal is according to the screen intensity of the target light intensity adjustment mobile terminal, and terminates this flow.
In the embodiment of the present invention, mobile terminal is using the difference of the first amplitude of variation and the second amplitude of variation to the first light
Line intensity is modified after obtaining target light intensity, can be further according to the target light intensity adjustment mobile terminal
Screen intensity, so as to improve the accuracy of screen intensity adjusting.
Specifically, mobile terminal can according to the concrete mode of the screen intensity of the target light intensity adjustment mobile terminal
To include the following steps：
11) target screen corresponding with the target light intensity is obtained in the relationship from preset light intensity with screen intensity
Curtain brightness；
12) by the current screen brightness regulation of the mobile terminal to target screen intensity.
In the specific implementation, mobile terminal can pre-set the relationship of light intensity and screen intensity, can be specifically light
Line intensity is in a linear relationship with screen intensity or light intensity is divided into multiple ranges, and each range corresponds to one
The screen intensity of grade, the embodiment of the present invention do not limit.
Therefore, mobile terminal is using the difference of the first amplitude of variation and the second amplitude of variation to carry out the first light intensity
After amendment, the corresponding target screen of target light intensity can be further obtained in the relationship from preset light intensity with screen intensity
Curtain brightness, thus by the current screen brightness regulation of mobile terminal to target screen intensity.
As it can be seen that in the described methods of Fig. 1, mobile terminal can combine light sensor at the end of user's communication
With RGB sensors whether light sensor is determined with the amplitude of variation of the light intensity detected during end of conversation before the call
Be stained with last layer greasy dirt, if it is confirmed that have, mobile terminal the light intensity that light sensor detects can be modified after again
Screen intensity is adjusted, light sensor can be thus solved and be blocked by greasy dirt and cause light intensity detection is inaccurate to ask
Topic, so as to improve the accuracy of mobile terminal screen brightness regulation.
Referring to Fig. 2, Fig. 2 is the flow diagram of another screen luminance adjustment method disclosed by the embodiments of the present invention.
Wherein, method shown in Fig. 2 can be applied to smart mobile phone (such as Android phone, iOS mobile phones), tablet computer, palm electricity
The mobile terminals such as brain, personal digital assistant, mobile internet device and intelligent wearable device, the mobile terminal include light
Sensor and RGB sensors.As shown in Fig. 2, the screen luminance adjustment method may comprise steps of：
201st, the first light intensity at the end of the mobile terminal call that acquisition for mobile terminal light sensor detects,
And determine the first light intensity is detected relative to light sensor before the mobile terminal call the first of the second light intensity
Amplitude of variation.
202nd, mobile terminal determines RGB sensors detect at the end of the mobile terminal call light intensity relative to this
Second amplitude of variation of the light intensity that RGB sensors detect before mobile terminal call.
203rd, when the first light intensity is less than the second light intensity, mobile terminal judges whether the first amplitude of variation is more than
Second amplitude of variation, if so, performing step 205；If it is not, perform step 204.
In the embodiment of the present invention, the first light intensity is less than there are two types of the situations of the second light intensity, and one kind is that user is led to
The light intensity in environment and the light intensity before call are reduced really at the end of words, and another kind is ring before and after user's communication
Light intensity in border does not change, and only light sensor is stained with last layer greasy dirt so that light sensor detects
Light intensity it is lower than the light intensity before user's communication.
Therefore, when the first light intensity is less than the second light intensity, mobile terminal can be by judging the first variation width
The size of degree and the second amplitude of variation is reduced come the light determined in environment or light sensor is blocked and causes
The light intensity of detection is reduced.That is, if light sensor is blocked by greasy dirt, then the whether light in environment
Line intensity do not change or environment in light intensity reduced really, the first amplitude of variation can be more than second variation
Amplitude.On the contrary, if light sensor is not blocked by greasy dirt, then the first amplitude of variation may can be less than or equal to second
Amplitude of variation.
Therefore, when judging that the first amplitude of variation is more than the second amplitude of variation, indicate that the light sensor may quilt
Whether greasy dirt blocks, so the difference that mobile terminal further judges the first amplitude of variation and the second amplitude of variation is needed to be more than in advance
If threshold value, so as to further determine that whether light sensor is had greasy dirt to block.When judging that the first amplitude of variation is less than
Or during equal to the second amplitude of variation, mobile terminal just adjusts screen intensity according to the first light intensity.
As a kind of feasible embodiment, when the first light intensity is more than the second light intensity, mobile terminal may be used also
To judge whether the first amplitude of variation is less than the second amplitude of variation, if it is lower, being judged as the first amplitude of variation and the second variation
Whether the difference of amplitude is more than predetermined threshold value；If greater than or be equal to, just according to the first light intensity adjust screen intensity.
In the specific implementation, the situation that the first light intensity is more than the second light intensity is at the end of user's communication in environment
Light intensity is higher than the light intensity before call.If that light sensor is blocked by greasy dirt, the first amplitude of variation just should
This is smaller than the second amplitude of variation, if light sensor is not blocked by greasy dirt, the first amplitude of variation should just become with second
Change amplitude is very nearly the same.So mobile terminal needs further to judge the relationship of the first amplitude of variation and the second amplitude of variation.
If the first amplitude of variation is less than the second amplitude of variation, indicate that the light sensor may be blocked by greasy dirt, institute
Whether predetermined threshold value is more than with the difference that mobile terminal is needed further to judge the first amplitude of variation and the second amplitude of variation, so as to
It may further determine that whether light sensor is had greasy dirt to block.If the first amplitude of variation is greater than or equal to the second variation width
Degree, mobile terminal just adjust screen intensity according to the first light intensity.
204th, mobile terminal adjusts the screen intensity of the mobile terminal according to the first light intensity, and terminates this flow.
In the embodiment of the present invention, when the first light intensity is less than the second light intensity, that is, light sensor detects
When light intensity after user's communication in environment will be less than the light intensity in environment before call, if mobile terminal judges light extraction
First amplitude of variation of the light intensity that line sensor detects is less than or equal to the of the light intensity that detects of RGB sensors
Two amplitudes of variation, then indicate that light sensor not blocked by greasy dirt, mobile terminal is so as to directly according to the
One light intensity adjusts screen intensity.
In addition, after working as the first light intensity is more than the second light intensity, that is, light sensor detects user's communication
When light intensity in environment is higher than the light intensity in environment before call, if mobile terminal judges that light sensor is examined
First amplitude of variation of the light intensity measured is greater than or equal to the second variation width of the light intensity that RGB sensors detect
Degree, then may also indicate that light sensor there is no being blocked by greasy dirt, mobile terminal is so as to directly according to the first light
Line intensity adjusts screen intensity.
205th, mobile terminal judges whether the difference of the first amplitude of variation and the second amplitude of variation is more than predetermined threshold value, if
It is to perform step 206~207；If it is not, terminate this flow.
206th, mobile terminal is modified first light intensity using the difference, obtains target light intensity.
207th, mobile terminal is according to the screen intensity of the target light intensity adjustment mobile terminal, and terminates this flow.
Optionally, when mobile terminal judges that the difference of the first amplitude of variation and the second amplitude of variation is more than predetermined threshold value,
Namely when mobile terminal determines that light sensor is blocked by greasy dirt, mobile terminal can also export prompt message, to carry
Show that user removes the greasy dirt.
As a kind of feasible embodiment, this programme is mainly mobile terminal in the mould for opening automatic adjustment screen intensity
It is carried out under formula, if user needs to adjust screen intensity manually, then following steps can also be performed in the mobile terminal：
21) slide inputted in the specified region of mobile terminal is received；
22) screen intensity of mobile terminal is adjusted according to the glide direction of the slide and sliding force.
In the specific implementation, under the pattern for opening automatic adjustment screen intensity in mobile terminal, if user wants to adjust manually
Section, can slide in the specified region of mobile terminal.The specified region can be some region in mobile terminal touch screen,
The embodiment of the present invention is not construed as limiting.Mobile terminal can prestore the corresponding screen intensity of glide direction and adjust direction, such as to
Upper slide represents to increase screen intensity, and slide downward expression reduces screen intensity；It can also determine different sliding forces
Corresponding different screen intensity change rate, if sliding force is bigger, when adjusting screen intensity, screen intensity variation is also bigger；
Or determining that different sliding distances corresponds to different screen intensity variable quantity etc., the embodiment of the present invention does not limit.Wherein, it is sliding
Power degree can be the average dynamics in sliding process, or minimum dynamics, the embodiment of the present invention are not construed as limiting.
Therefore, when user is when this specifies region to input slide, mobile terminal can receive the slide,
And determine the glide direction and sliding force of slide, so as to be moved according to glide direction and sliding force to adjust
The screen intensity of dynamic terminal.In this way, if the screen intensity that is automatically adjusted to mobile terminal of user is dissatisfied, that
User can directly be adjusted screen intensity in the specified region of mobile terminal, so as to improve screen intensity adjusting
Efficiency promotes user experience.
For example, when specified region upward sliding of the user in mobile terminal, mobile terminal is according to determining user's need
Screen intensity is increased, mobile terminal so as to obtain user slip dynamics such as 5N.Assuming that the corresponding screen intensitys of 5N
Variable quantity is 2cd, then current screen brightness will be increased the brightness of 2cd by mobile terminal.
As it can be seen that in the described methods of Fig. 2, mobile terminal can be according to the light intensity that light sensor detects come just
Whether the light that step judges in environment changes or dimmed still brightens.If the dimming in environment, then only
The first amplitude of variation for having the light intensity detected in light sensor is more than the of the light intensity that detects of RGB sensors
During two amplitudes of variation, it just can confirm that light sensor is blocked；If the light in environment brightens, then only in light level
First amplitude of variation of the light intensity that device detects is less than the second amplitude of variation of light intensity that RGB sensors detect
When, it just can confirm that light sensor is blocked.In this way, mobile terminal can accurately determine in complex environment
Go out whether light sensor is blocked by greasy dirt, so as to improve the accuracy of screen intensity adjusting.
