Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearlyChu, intactly description, obviously, described embodiment is only the present invention's part embodiment, instead ofWhole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not making creationThe every other embodiment obtaining under property work prerequisite, belongs to the scope of protection of the invention.
The embodiment of the invention discloses a kind of screen intensity control method and mobile terminal, can improve eventually mobileThe degree of accuracy that end screen intensity regulates. Below be elaborated respectively.
Refer to Fig. 1, Fig. 1 is the flow process signal of the disclosed a kind of screen intensity control method of the embodiment of the present inventionFigure. Wherein, the method shown in Fig. 1 can be applied to smart mobile phone (as Android mobile phone, iOS mobile phone etc.),Panel computer, palm PC, personal digital assistant (PersonalDigitalAssistant, PDA), mutually mobileThe mobile terminals such as networked devices (MobileInternetDevice, MID) and intelligent wearing equipment, this movesMoving terminal includes light sensor and RGB sensor. As shown in Figure 1, this screen intensity control method canTo comprise the following steps:
101, the first light when this mobile terminal call that acquisition for mobile terminal light sensor detects finishesIntensity, and determine the first light intensity with respect to this mobile terminal call before light sensor detect secondThe first amplitude of variation of light intensity.
In the embodiment of the present invention, the front of mobile terminal is that screen side is provided with light sensor, and this light passesSensor is mainly arranged near receiver, can detect the light intensity of external environment, thereby mobile terminal canAccording to the automatic adjusting screen brightness of light intensity. The back side of mobile terminal is that bonnet side is provided with RGB sensor,This RGB sensor is the components and parts in mobile terminal camera, and being mainly used in provides red R, green for cameraThe parameter of G, blue B three primary colours, the white balance parameter of taking pictures to promote camera, thus can obtain effect moreGood photo. RGB sensor is arranged on the position near post-positioned pick-up head conventionally, and this RGB sensor also canTo calculate light intensity according to the parameter of the RGB three primary colours that detect by special algorithm. That is to say,The light intensity of RGB sensor in also can testing environment.
In the embodiment of the present invention, light sensor and the RGB sensor light in can real-time testing environment is strongDegree. Therefore,, in the time that mobile terminal detects that user's communication finishes, can obtain light sensor and detect currentThe first light intensity of environment, the first light intensity that when user's communication finishes, light sensor detects.Meanwhile, the historical light intensity that mobile terminal can detect from pre-recorded light sensor, obtaining user existsThe second light intensity detecting before call, thus can determine that the first light intensity is strong with respect to the second lightThe first amplitude of variation of degree.
Under normal circumstances, after having made a call, can there is one deck greasy dirt, this greasy dirt in user on mobile phone screenIf sticked near light sensor, may will affect the degree of accuracy of the light intensity of light sensor detection.Therefore, mobile phone can detect respectively obtaining light sensor after user has made a call and before making a phone callThe first amplitude of variation of light intensity.
102, mobile terminal is determined the light intensity that when this mobile terminal call finishes, RGB sensor detectsWith respect to the second amplitude of variation of the light intensity that before this mobile terminal call, RGB sensor detects.
In the embodiment of the present invention, mobile terminal obtain light sensor in the time that user's communication finishes with respect to logicalWhen the first amplitude of variation of the light intensity before words, also can obtain the user that RGB sensor detects and existThe second amplitude of variation of the light intensity before call with respect to user of light intensity when end of conversation. Therefore,Step 102 can be carried out with step 101 simultaneously, and the embodiment of the present invention does not limit.
It should be noted that, under normal circumstances, although light sensor and RGB sensor are at synchronizationThe light intensity that current environment detected might not equate, but light sensor and RGB sensor are in phaseThe amplitude of variation of the light intensity that same two moment detect separately differs should be smaller. If but work as lightLine sensor is blocked, as is stained with one deck greasy dirt, the light in two moment that light sensor detects soThe amplitude of variation of the light intensity in identical two moment that the amplitude of variation of intensity detects with RGB may differWill be larger.
103, mobile terminal judges whether the difference of the first amplitude of variation and the second amplitude of variation is greater than predetermined threshold value,If so, perform step 104; If not, process ends.
In the embodiment of the present invention, when mobile terminal gets respectively light intensity that light sensor detectsAfter the second amplitude of variation of the light intensity that the first amplitude of variation and RGB sensor detect, mobile terminalCan further determine the difference between the first amplitude of variation and the second amplitude of variation, thereby come really according to this differenceWhether determine light sensor is blocked.
Concrete, mobile terminal is whether the difference by judging the first amplitude of variation and the second amplitude of variation is largeJudge in predetermined threshold value whether this light sensor is blocked. Wherein, this predetermined threshold value is mainly certain for the momentBetween in section as the amplitude of variation phase of the light intensity in identical two moment of detecting of nearly one week interior two sensorPoor mean value, is mainly the amplitude of variation that detects light intensity in the time conversing, and this predetermined threshold value canVery little to be set to, as 5cd (wherein, cd is that candela is the unit of weighing light intensity size), concreteValue need to be according to the light source of the sensitivity of two light sensors and the frequent environment of living in of mobile terminal as a lightSource or area source etc. are definite, and the embodiment of the present invention does not limit.
Therefore, be greater than default if mobile terminal is judged the difference of the first amplitude of variation and the second amplitude of variationThreshold value, will be used this difference to revise the first light intensity so, obtains target light line strength. AsThe difference that fruit mobile terminal is judged the first amplitude of variation and the second amplitude of variation is less than or equal to predetermined threshold value,So just show that light sensor may not be blocked, after user's communication finishes, user on the face or hairOn greasy dirt do not attach near light sensor, thereby show that the light that light sensor detects is strongIt is more accurate to spend, and mobile terminal just can detect that the first light intensity regulates according to this light sensor soScreen intensity.
104, mobile terminal uses this difference to revise this first light intensity, obtains target light line strength.
In the embodiment of the present invention, when mobile terminal is judged the difference of the first amplitude of variation and the second amplitude of variationWhile being greater than predetermined threshold value, just show that light sensor has been blocked, after user's communication finishes, user on the faceOr greasy dirt on hair attaches near light sensor, the light intensity that light sensor detects so alsoInaccurate, so the light intensity that mobile terminal need to detect this light sensor is revised. Therefore,The first light intensity that this mobile terminal just can use this difference to detect light sensor is revised,Obtain target light line strength.
It should be noted that, the first light that mobile terminal just uses this difference to detect light sensor is strongThe major way that degree is revised is that the first light intensity is added to this difference, obtains target light line strength. LogicalCross this mode and can reduce the decay of the light intensity detecting due to the light sensor that greasy dirt causes, fromAnd while making mobile terminal according to the brightness of light intensity adjusting screen, the adjusting of screen intensity meets environment moreActual light line strength, that is to say and can improve the degree of accuracy that screen intensity regulates, thereby promote user bodyTest.
Optionally, mobile terminal also can calculate light according to the difference of the first amplitude of variation and the second amplitude of variationLine sensor is being stained with the attenuation ratio that detects light intensity after greasy dirt, thereby can come by this attenuation ratioThe first light intensity that light sensor is detected is revised, and obtains target light line strength.
105, mobile terminal regulates the screen intensity of this mobile terminal according to this target light line strength, and finishes thisFlow process.
In the embodiment of the present invention, mobile terminal is using the difference pair of the first amplitude of variation and the second amplitude of variationThe first light intensity correction obtains after target light line strength, can be further according to this target light line strengthRegulate the screen intensity of this mobile terminal, thereby can improve the degree of accuracy that screen intensity regulates.
Concrete, mobile terminal regulates screen intensity concrete of this mobile terminal according to this target light line strengthMode can comprise the following steps:
11) from the relation of default light intensity and screen intensity, obtain with this target light line strength correspondingTarget screen intensity;
12) by the current screen brightness regulation of this mobile terminal to target screen intensity.
In specific implementation, mobile terminal can set in advance the relation of light intensity and screen intensity, specifically canLinear to be light intensity and screen intensity, can be also that light intensity is divided into multiple scopes,The screen intensity of the corresponding grade of each scope, the embodiment of the present invention does not limit.
Therefore, mobile terminal is using the difference of the first amplitude of variation and the second amplitude of variation strong to the first lightAfter degree is revised, can further from the relation of default light intensity and screen intensity, obtain target lightThe target screen intensity that intensity is corresponding, thereby by bright to target screen the current screen brightness regulation of mobile terminalDegree.
Visible, in the described method of Fig. 1, mobile terminal, can be in conjunction with light in the time that user's communication finishesThe amplitude of variation of the light intensity that line sensor and RGB sensor detect during with end of conversation before call is comeDetermine whether light sensor is stained with one deck greasy dirt, if confirm to have, mobile terminal can be to light sensorThe light intensity detecting is adjusting screen brightness again after revising, and so just can solve light sensor quiltGreasy dirt blocks and causes light intensity to detect inaccurate problem, thereby can improve mobile terminal screen brightnessThe degree of accuracy regulating.
Refer to Fig. 2, Fig. 2 is that the flow process of the disclosed another kind of screen intensity control method of the embodiment of the present invention is shownIntention. Wherein, the method shown in Fig. 2 can be applied to smart mobile phone (as Android mobile phone, iOS mobile phoneDeng), panel computer, palm PC, personal digital assistant, mobile internet device and intelligent wearing equipmentDeng mobile terminal, this mobile terminal includes light sensor and RGB sensor. As shown in Figure 2, this screenCurtain brightness adjusting method can comprise the following steps:
201, the first light when this mobile terminal call that acquisition for mobile terminal light sensor detects finishesIntensity, and determine the first light intensity with respect to this mobile terminal call before light sensor detect secondThe first amplitude of variation of light intensity.
202, mobile terminal is determined the light intensity that when this mobile terminal call finishes, RGB sensor detectsWith respect to the second amplitude of variation of the light intensity that before this mobile terminal call, RGB sensor detects.
203,, in the time that the first light intensity is less than the second light intensity, mobile terminal judges that the first amplitude of variation isNo second amplitude of variation that is greater than, if so, performs step 205; If not, execution step 204.
In the embodiment of the present invention, the situation that the first light intensity is less than the second light intensity has two kinds, Yi ZhongshiLight intensity before light intensity when user's communication finishes in environment and call reduces really to some extent, another kindBe that before and after user's communication, the light intensity in environment does not change, just light sensor is stained with one deckGreasy dirt, the light intensity before making light intensity that light sensor detects than user's communication is low.
Therefore,, in the time that the first light intensity is less than the second light intensity, mobile terminal can be by judging firstThe size of amplitude of variation and the second amplitude of variation determines it is that light in environment reduces or light sensing to some extentDevice is blocked and causes the light intensity detecting to reduce to some extent. That is to say, if light sensor is by greasy dirtBlock, no matter be that light intensity in environment does not change so, or the light intensity in environment has reallyInstitute reduces, and the first amplitude of variation all can be greater than the second amplitude of variation. On the contrary, if light sensor not by oilDirty institute blocks, and the first amplitude of variation just may be less than or equal to the second amplitude of variation so.
Therefore,, in the time judging the first amplitude of variation and be greater than the second amplitude of variation, just show this light sensorMay be blocked by greasy dirt, so need mobile terminal further to judge the first amplitude of variation and the second amplitude of variationDifference whether be greater than predetermined threshold value, thereby can further determine whether light sensor is had greasy dirt to block.In the time judging the first amplitude of variation and be less than or equal to the second amplitude of variation, mobile terminal is just according to the first lightIntensity adjustment screen intensity.
As a kind of feasible embodiment, in the time that the first light intensity is greater than the second light intensity, eventually mobileEnd can also judge whether the first amplitude of variation is less than the second amplitude of variation, if be less than, just judges the first changeWhether the difference of change amplitude and the second amplitude of variation is greater than predetermined threshold value; If be more than or equal to, just according toOne light intensity adjusting screen brightness.
In specific implementation, the situation that the first light intensity is greater than the second light intensity is user's communication ring while finishingLight intensity in border is higher than the light intensity before conversing. If light sensor is blocked by greasy dirt so,The first amplitude of variation just should be less than the second amplitude of variation, if light sensor is not blocked by greasy dirt,The first amplitude of variation just should be very nearly the same with the second amplitude of variation. So mobile terminal needs further judgementThe relation 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, just show that this light sensor may be hidden by greasy dirtGear, so need mobile terminal further to judge that whether the difference of the first amplitude of variation and the second amplitude of variation is largeIn predetermined threshold value, thereby can further determine whether light sensor is had greasy dirt to block. If first becomesChange amplitude is more than or equal to the second amplitude of variation, and mobile terminal is just according to the first light intensity adjusting screen brightness.
204, mobile terminal regulates the screen intensity of this mobile terminal according to the first light intensity, and finishes this streamJourney.
In the embodiment of the present invention, when the first light intensity is less than the second light intensity, namely light sensorDetect when the light intensity in environment after user's communication will be lower than light intensity in environment before call, ifThe first amplitude of variation that mobile terminal is judged the light intensity that light sensor detects is less than or equal to RGBThe second amplitude of variation of the light intensity that sensor detects, so just shows that light sensor is not by oilDirty institute blocks, thereby mobile terminal can directly carry out adjusting screen brightness according to the first light intensity.
In addition,, when the first light intensity is greater than the second light intensity, namely light sensor detects userWhen light intensity after call in environment will be higher than light intensity in environment before call, if mobile terminal is sentencedThe first amplitude of variation that the light intensity that light sensor detects of breaking is greater than or equals RGB sensor and detectsThe second amplitude of variation of the light intensity arriving, so also can show that light sensor is not hidden by greasy dirtGear, thus mobile terminal can directly carry out adjusting screen brightness according to the first light intensity.
205, mobile terminal judges whether the difference of the first amplitude of variation and the second amplitude of variation is greater than predetermined threshold value,If so, perform step 206～207; If not, process ends.
206, mobile terminal uses this difference to revise this first light intensity, obtains target light line strength.
207, mobile terminal regulates the screen intensity of this mobile terminal according to this target light line strength, and finishes thisFlow process.
Optionally, the difference of judging the first amplitude of variation and the second amplitude of variation when mobile terminal is greater than defaultThreshold value, namely, in the time that mobile terminal is determined light sensor and blocked by greasy dirt, mobile terminal can also be defeatedGo out information, to point out user to remove this greasy dirt.
As a kind of feasible embodiment, this programme is mainly that mobile terminal is bright at the automatic adjusting screen of unlatchingUnder the pattern of degree, carry out, if when user needs manual adjustments screen intensity, this mobile terminal also can soTo carry out following steps:
21) be received in the slide of the appointed area input of mobile terminal;
22) according to the screen intensity of the glide direction of this slide and slip dynamics adjusting mobile terminal.
In specific implementation, open at mobile terminal under the pattern of automatic adjusting screen brightness, if user wantsManual adjustments, can slide in the appointed area of mobile terminal. This appointed area can be that mobile terminal touchesSome regions in screen, the embodiment of the present invention is not construed as limiting. Mobile terminal can pre-stored glide directionCorresponding screen intensity regulates direction, as upward sliding represents screen intensity to increase, down sliding represent byScreen intensity reduces; Can also determine the screen intensity rate of change that different slip dynamics is corresponding different, as cunningPower degree is larger, and in the time of adjusting screen brightness, screen intensity changes also just greatly; Or determine different slipsThe screen intensity variable quantities that distance is corresponding different etc., the embodiment of the present invention does not limit. Wherein, slip dynamicsCan be the average dynamics in sliding process, can be also minimum force degree, and the embodiment of the present invention is not construed as limiting.
Therefore,, in the time that user inputs slide in this appointed area, mobile terminal just can receive this cunningMoving operation, and determine glide direction and the slip dynamics of slide, thus can be according to glide directionRegulate the screen intensity of mobile terminal with slip dynamics. In this way, if user to mobile terminalAutomatically the screen intensity regulating is dissatisfied, so user can be directly in the appointed area of mobile terminal to shieldingCurtain brightness regulates, thereby has improved the efficiency that screen intensity regulates, and promotes user and experiences.
For instance, when user is during at the appointed area of mobile terminal upward sliding, mobile terminal is according to determiningUser need to increase screen intensity, thereby mobile terminal can obtain the dynamics of user's slip as 5N. SupposeThe screen intensity variable quantity that 5N is corresponding is 2cd, and mobile terminal will increase 2cd by current screen brightness soBrightness.
Visible, in the described method of Fig. 2, the light that mobile terminal can detect according to light sensorIntensity tentatively judges whether the light in environment changes, or dimmedly still brightens. If environmentIn light dimmed, the first amplitude of variation of the light intensity so only detecting at light sensor is greater thanWhen the second amplitude of variation of the light intensity that RGB sensor detects, could confirm that light sensor is blocked;If the light in environment brightens, first of the light intensity so only detecting at light sensor changesWhen amplitude is less than the second amplitude of variation of the light intensity that RGB sensor detects, could confirm light sensingDevice is blocked. In this way, mobile terminal can be determined accurately light biography in complex environmentWhether sensor is blocked by greasy dirt, thereby can improve the degree of accuracy that screen intensity regulates.
Refer to Fig. 3, Fig. 3 is the structural representation of the disclosed a kind of mobile terminal of the embodiment of the present invention. Wherein,Mobile terminal 300 shown in Fig. 3 can include but not limited to that smart mobile phone is (as Android mobile phone, iOS handMachine etc.), panel computer, palm PC, personal digital assistant, mobile internet device and intelligence dresses and establishesThe standby mobile terminal that possesses light sensor and RGB sensor that waits. As shown in Figure 3, this mobile terminal 300Can comprise with lower unit:
Acquiring unit 301, when obtaining this mobile terminal 300 end of conversation that light sensor detectsThe first light intensity.
Determining unit 302, for determining that the first light intensity passes with respect to the front light of this mobile terminal 300 callThe first amplitude of variation of the second light intensity that sensor detects, and determine these mobile terminal 300 end of conversationsTime the RGB sensor light intensity that detects with respect to these mobile terminal 300 calls before the inspection of RGB sensorThe second amplitude of variation of the light intensity measuring.
