In one embodiment of the invention, residing for monitoring electronic equipment, the environmental light intensity of environment, obtains a monitoring result; Judge that whether monitoring result meets one pre-conditioned; When monitoring result meet one pre-conditioned time, the brightness of adjustment display unit, wherein, the brightness after adjustment is compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, and first changes curvature and environmental light intensity adapts.This shows, method in the present embodiment, first the environmental light intensity of environment residing for electronic equipment is monitored, obtain a monitoring result, and it is one pre-conditioned to judge that whether monitoring result meets, only when monitoring result meets pre-conditioned, just adjust the brightness of display unit, any judgement is not done so just avoid, as long as often detect an environmental light intensity, the problem that the adjustment that this scheme of brightness with regard to adjusting display unit is brought is not accurately, stability is lower; Further, in the present embodiment, when adjusting the brightness of display unit, the result of adjustment is: the brightness after adjustment is compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, and first changes curvature and environmental light intensity and adapt, so compared with scheme of carrying out adjusting all the time with same rate of change of the prior art, the scheme of the present embodiment considers the relation between environmental light intensity and change curvature, makes adjustment more accurate, improves Consumer's Experience.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
The embodiment of the present invention provides a kind of method adjusting brightness, is applied to one and has on the electronic equipment of display unit, and this electronic equipment is such as the electronic equipments such as mobile phone, panel computer, notebook computer.
Please refer to Fig. 1, the method comprises:
Step 101: the environmental light intensity of environment residing for monitoring electronic equipment, obtains a monitoring result;
Step 102: judge that whether monitoring result meets one pre-conditioned;
Step 103: when monitoring result meets pre-conditioned, the brightness of adjustment display unit, wherein, the brightness after adjustment is compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, the first change curvature and environmental light intensity adapt.
Wherein, in a step 101, the environmental light intensity of environment residing for monitoring electronic equipment, concrete example is Real-Time Monitoring environmental light intensity in this way, and namely optical sensor (light sensor) is always in running order, Real-time Obtaining environmental light intensity data; Can also be specifically periodic monitoring, such as just obtain once every 5s, certainly, in practice, this cycle can also be other numerical value, such as 10s, 30s.
No matter pass through monitoring mode how, all can obtain a monitoring result, in practice, may be different due to the mode of monitoring, the monitoring result of acquisition is also incomplete same, and this part will be described in detail in follow-up continuation.
Next when after acquisition one monitoring result, perform step 102, namely judge that whether satisfied monitoring result is one pre-conditioned.
In a step 102, pre-conditioned have numerous embodiments, specifically pre-conditionedly arrange and can arrange according to the actual requirements, if such as want to obtain more stable brightness adjustment in dimmed according to light intensity, so just can arrange pre-conditioned be exactly environmental light intensity really dimmed, instead of unexpected flicker; Again such as, if adopt different adjustment curves respectively when wanting the dimmed and environmental light intensity of environmental light intensity to brighten, so pre-conditioned just can arrange can determine that current environment light intensity is dimmed or brighten.Certainly, the monitoring mode of pre-conditioned setting also with concrete is relevant, such as also for ease of and determine environmental light intensity really dimmed, instead of unexpected flicker, monitoring mode can be monitor from the continuity of time and the continuity of monitoring number of times, and so the pre-conditioned of correspondence is just arranged from the continuity of time and the continuity of monitoring number of times respectively.
One pre-conditioned by judging that whether monitoring result meets, improve the condition of adjustment brightness, so it is whole to decrease some mistunings, improve accuracy and the stability of adjustment.
Then next perform step 103, namely when monitoring result meet this pre-conditioned time, the just brightness of adjustment display unit.
In this step, the brightness of adjustment display unit can be specifically adjust based on the mapping table between environmental light intensity and brightness, can also be adjusted by the functional relation between brightness and environmental light intensity.And concrete adjustment direction (tune amount or dim) is relevant to monitoring result, this part also will be described in detail follow-up.Through the adjustment of step 103, make the brightness after adjusting compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, and also first changes curvature and environmental light intensity and adapts.
As can be seen from foregoing description, by the method for the present embodiment, avoid and do not do any judgement, as long as often detect an environmental light intensity, the problem that the adjustment that this scheme of brightness with regard to adjusting display unit is brought not accurately, stability is lower, namely in the present embodiment scheme, improve the condition of the brightness of adjustment display unit, make adjustment more accurate, the stability of brightness is also better, improves Consumer's Experience.Further, in the present embodiment, when adjusting the brightness of display unit, the result of adjustment is: the brightness after adjustment is compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, and first changes curvature and environmental light intensity and adapt, so compared with scheme of carrying out adjusting all the time with same rate of change of the prior art, the scheme of the present embodiment considers the relation between environmental light intensity and change curvature, makes adjustment more accurate, improves Consumer's Experience.
The concrete enforcement scene of the method for the adjustment brightness of the present embodiment will be described in detail below.
Implement in scene first, step 101 is specially: continuously one schedule time of monitoring, obtain N number of Monitoring Data, wherein, N be more than or equal to 2 integer, such as monitor 30s continuously, obtain 10 Monitoring Data.
So step 102 is specially: judge whether N number of Monitoring Data diminishes according to monitoring time order, namely judges whether the trend that environmental light intensity diminishes continue for this schedule time.Such as these 10 Monitoring Data are successively 45,45,20,3,3,3,2,2,2,2 according to monitoring time, because to end from monitoring time, the trend of environmental light intensity reduces, so can determine that environmental light intensity is diminishing really, so just can determine that this monitoring result meets pre-conditioned.
Then perform step 103, namely adjust the brightness of display unit, in the present embodiment, step 103 specifically based on the brightness of a pre-defined rule adjustment display unit, makes brightness and environmental light intensity adapt.In specific implementation process, pre-defined rule has multiple example, such as, prestored the mapping table between an environmental light intensity and brightness in the electronic device, please refer to table one:
| Environmental light intensity | Optical sensor | Brightness |
| 1 | 0 | 5 |
| 2 | 1 | 48 |
| 3 | 4 | 48 |
| 20 | 8 | 48 |
| 45 | 12 | 60 |
| 75 | 20 | 85 |
| 140 | 37 | 110 |
| 190 | 48 | 160 |
Table one
In Table 1, the first hurdle " environmental light intensity " represents the intensity rank of environmental light intensity, and the second hurdle " optical sensor " represents the raw data of the environmental light intensity that light sensors arrives, and third column " brightness " represents the luminance parameter of the brightness of adjustment display unit.In practice, in step 101, monitoring of environmental light intensity, the Monitoring Data of acquisition can refer to the raw data that optical sensor obtains, and also can be to convert the intensity rank of coming according to the corresponding relation of table one, is all described for intensity rank below.Data in table one are through the data that test of many times draws, adjust according to the data of table one, and the brightness of display unit is more accurate, more stable, is more conducive to protect the eyes of user.
Further, in the present embodiment, pre-defined rule also comprises intensity rank with being as the criterion of monitoring for the last time, continue for previous example, namely intensity rank is 2, so just can determine that brightness is 48 according to table one, and the brightness then with regard to adjusting display unit becomes 48.
Certainly, in practice, pre-defined rule can also be other rule, such as intensity rank is as the criterion with the mean value of last three times, can also be that intensity rank is lower, the change curvature of adjustment be less, certainly, here the less trend that refers to reduces, and adjacent change curvature can have identical, such as when intensity rank is varied down to 20 from 45, if adjust brightness, so the change curvature of brightness is the first sub-curvature, when intensity rank is varied down to 3 from 20, if adjust brightness, so the change curvature of brightness is the second sub-curvature, when intensity rank is varied down to 2 from 3, if adjust brightness, so the change curvature of brightness is the 3rd sub-curvature, so the first sub-curvature is greater than the second sub-curvature, second sub-curvature is greater than the 3rd sub-curvature, wherein, change curvature can refer to adjusts to by original luminance value the number percent that present intensity value reduces, if such as based on the numerical value of table one, instead can release the first sub-curvature is 20%, second sub-curvature and the 3rd sub-curvature are 0, the numerical value of table one can not certainly be used, but set the first sub-curvature in advance to the 3rd sub-curvature, such as first sub-curvature is 20%, second sub-curvature is 15%, 3rd sub-curvature is 10%, during each adjustment, the change curvature that electronic equipment just sets according to these carries out calculating should be adjusted to how many.
In another embodiment, change curvature can also be the slope of intensity rank-brightness change curve, same for previous example, when intensity rank is 45, brightness is 60, and intensity rank is when being 20, brightness is 48, so on this change curve, the slope of the line between these 2 is 0.48, namely the first sub-curvature is 0.48, and certainly, this pushes away according to the data in table one are counter, in practice, can by setting change curvature, calculated in advance obtains the data of table one, so in use direct question blank one.Also can be: first based on environmental light intensity, determine the first change curvature, then based on the brightness of the first change curvature adjustment display unit, namely each all environmentally light intensity determines the first change curvature, then should adjust brightness to how many according to the first change curvature estimation.
Because human eye is in the dark comparatively responsive to the change of CD-ROM drive, so in embodiments of the present invention, change curvature is set to diminish along with environmental light intensity and is the trend reduced, so more accurately control electronic equipment environmentally light intensity adjustment display unit brightness, and make user can not be more with dazzling feeling when environmental light intensity is darker, avoid eyes of user uncomfortable, improve Consumer's Experience.
Implement in scene second, with first implements scene unlike, step 101 is specially: monitor pre-determined number continuously, obtains M Monitoring Data, wherein, M be more than or equal to 2 integer, such as monitoring 10 times continuously, obtains 10 Monitoring Data.Step 102 is specially: whether M Monitoring Data diminishes according to monitoring time order; Wherein, when M detection data diminish according to monitoring time order, represent that monitoring result meets pre-conditioned.Such as these 10 Monitoring Data are successively 45,45,20,3,3,3,2,2,2,2 according to monitoring time, because to end from monitoring time, the trend of environmental light intensity reduces, so can determine that environmental light intensity is diminishing really, so just can determine that this monitoring result meets pre-conditioned.Next perform step 103 again, namely adjust the brightness of display unit, this part can the first embodiment implemented in scene similar, so succinct in order to instructions, be not described in detail in this.
3rd implements scene, and in the present embodiment, step 101 is specially: during from the brightness of previous adjustment display unit, and monitoring of environmental light intensity obtains first environment light intensity; Step 102 is specially: whether the intensity rank difference between second environment light intensity corresponding when judging the brightness of first environment light intensity with previous adjustment display unit is more than or equal to 2, if so, then represents that monitoring result meets pre-conditioned.Such as, just continue monitoring of environmental light intensity after at every turn adjust the brightness of display unit, acquisition first environment light intensity is such as 3, and when adjusting based on environmental light intensity be second environment light intensity, be such as 45; Then judge whether the intensity rank difference between first environment light intensity and second environment light intensity is more than or equal to 2, known according to table one, intensity rank is from 45 to 3, and just intensity rank difference is 2, so just represents that monitoring result meets pre-conditioned.
Then at this moment just perform step 103, namely adjust the brightness of display unit, the embodiment of this part is similar to the first enforcement scene, so be not described in detail in this.
4th implements scene, and in the present embodiment, step 102 is specially and judges whether environmental light intensity is diminishing, and if so, then represents that monitoring result meets pre-conditioned; Wherein, here judge whether environmental light intensity is diminishing, can be judged by above-mentioned three methods implementing to introduce in scene, as long as can certainly judge to diminish than previous Monitoring Data, just can be confirmed to be and diminish, such as, a upper Monitoring Data is 45, the data monitored specifically are 20, so just can think to have diminished.
Then perform step 103, be specially: dimmed with the brightness of the first change curvature adjustment display unit, wherein, environmental light intensity is less, and the first change curvature is less.Wherein, the implication of the first change curvature can be the change curvature described in the first enforcement scene, also can be the change curvature of other formal definitions, as long as when making environmental light intensity more diminish, the brightness change of display unit is also less.
By finding out the description that four are implemented scene above, by the technical scheme of the present embodiment, the brightness flicker of display unit can also be avoided, this enforcement is by confirming whether monitoring result satisfies condition, whether such as environmental light intensity is certain is diminishing,, then adjust the brightness of display unit if so.Such as environmental light intensity is all in more stable always and is brighter state, just contingency detect that environmental light intensity is lower, object is such as had accidentally to shelter from light, according to the scheme of the prior art described in background technology, will immediately by brightness adjustment to darker state, but at once the environmental light intensity that a value is larger detected again, then just adjust to brighter state immediately again, so the flickering of display unit will be caused, the eyes of user are made to have sense of discomfort.And if the scheme in the present embodiment, would not just adjust display brightness, so avoid flickering when once in a while dimmed.
Further, in the present embodiment, when adjusting the brightness of display unit, the result of adjustment is: the brightness after adjustment is compared to the first change curvature of the brightness before adjustment, different from change curvature during previous adjustment, and first changes curvature and environmental light intensity and adapt, so compared with scheme of carrying out adjusting all the time with same rate of change of the prior art, the scheme of the present embodiment considers the relation between environmental light intensity and change curvature, makes adjustment more accurate, improves Consumer's Experience.
In another embodiment, step 102 is specifically as follows: judge whether monitoring result is less than or equal to a threshold value, and if so, namely when environmental light intensity is darker, the method that so step 103 is just implemented to describe in scene according to aforementioned first to fourth adjusts; And if not, so step 103 just can adopt other modes to adjust, such as, change the constant mode of curvature.
And large situation is become for environmental light intensity, as long as can be have to become large, just the brightness of display unit is adjusted, the brightness of display unit is brightened, the change curvature of adjustment can become large greatly along with the change of environmental light intensity, other adjustment modes can certainly be adopted, such as, change the identical mode of curvature.
