Embodiment
Describe embodiments of the present invention in detail below with reference to drawings and Examples, how the application technology means solve technical matters to the present invention whereby, and the implementation procedure of reaching technique effect can fully understand and implements according to this.
Because the real-time that existing ALS scheme has, at ambient lighting variation of short duration, in more among a small circle taking place once in a while (passes by the angle of blocking light source irradiates light sensor as personnel, Deng) time, screen intensity also can be along with changing, cause screen intensity that shake among a small circle takes place, influencing the user and experience, also is that surround lighting changes slightly, and the brightness of screen will change to some extent.Therefore, existing ALS solution will be because its real-time will be brought the risk of potential screen intensity shake, and because the brightness value of system time ambient light, and correspondingly adjust action, so frequent adjustment must be accelerated screen aging, reduce the life-span of screen, also increased the power consumption of system simultaneously to a certain extent.
In the prior art, the user of electronic equipment such as notebook computer etc. can also adjust screen intensity by function key, power source design setting, power management multiple modes such as (PM Utility).Because principle is adjusted in the brightness of power source design setting, power management etc., the brightness adjustment principle of adjusting with the Fn function key is the same substantially, therefore, if no special instructions, hereinafter will adjust mode by multiple screen intensity such as function key, power source design setting, power management (PM Utility), system is referred to as from the subjective brightness adjustment.
But in the existing solution, because the real-time that ALS brightness is adjusted, can't enable simultaneously that ALS adjusts and from the subjective brightness adjustment, this is the limitation decision of the solution thought adjusted by ALS brightness itself, the sense cycle that is the ALS sensor is very short, and general a few tens of milliseconds is just detected and export ambient light one time.If be that the ALS of 2n millisecond adjusts mode by the cycle, when the T millisecond, screen intensity adjusted to N (T), when the T+n millisecond, the user adjusts mode by brightness such as function keys screen intensity is adjusted to N (T+n), even if ambient light does not change fully like this, when the T+2n millisecond, system still can adjust back to screen intensity N (T), also namely when the T+2n millisecond, screen intensity N (T+2n) equals brightness N (T).Enable ALS brightness adjustment and function key brightness adjustment in suc scheme simultaneously, if the user thinks that the current brightness of screen is not suitable for current ongoing application (as playing or seeing a film, need the screen intensity value that original ALS sets be lightened or dim by the Fn function key), can't be by realizations such as Fn function keys.Even because carry out the brightness adjustment by Fn function key etc., ALS brightness adjustment will be withdrawn into original set ALS brightness value by the interior brightness value with the adjustment of Fn function key of next adjustment cycle again, the user originally desires to adjust screen intensity by the function key mode, make screen brightness significant change in the short time (2n millisecond) on the contrary, thereby cause the user uncomfortable even may make the user think the doubt that equipment breaks down etc.If the user continues to attempt the autonomous screen intensity of adjusting, screen then can occur and continue flicker, even also occur the problem of internal system program code confusion probably.
This shows that because the real-time of scheme is adjusted in ALS brightness, brightness adjustment such as function key will be lost efficacy.Adjust mode if enable ALS brightness, then function key etc. is adjusted mode from subjective brightness and not only can not be reached the utility function that screen intensity is adjusted, and can bring to use to the user on the contrary and go up or doubt that equipment breaks down.Given this, to adjust adjustment schemes such as scheme and Fn function key be exclusive in ALS brightness in the prior art, generally is in ALS brightness adjustment and enables a kind of brightness and adjust mode and forbid another kind of brightness adjustment mode simultaneously in the subjective brightness adjustment.Such as enable ALS brightness when adjusting function brightness such as disable function key adjust function, enable brightness such as function key when adjusting forbidding ALS brightness adjust function, avoid screen intensity shake and the problems such as code conflict that may cause with this.
Fig. 2 is the schematic flow sheet of screen intensity method of adjustment one embodiment of the present invention.As shown in Figure 2, this method mainly comprises the steps:
Step S210 by the ALS sensor, obtains an ambient light value A and storage under the current environment;
Step S220 according to the ambient light value A that stores, obtains the ambient light variable quantity in the certain hour scope
In the present embodiment, be by ALS sensor relatively second constantly T2 detect second environment illuminance value At2 and before detected first environment illuminance value At1 during at first moment T1, obtain this ambient light variable quantity
Step S230 judges this ambient light variable quantity
Surpass a default detection threshold
Namely
Greater than
This ambient light variable quantity surpasses this detection threshold, it is comparatively violent to illustrate that ambient light changes, may influence user's experience largely, default brightness regularization condition before having satisfied need be made suitable adjustment so that the user obtains the information on the screen better;
Step S240, according to this ambient light value A under detected this current environment (also i.e. this second environment illuminance value At2), search default brightness curve or look-up table, determine a target brightness value that be used for to adjust the display device screen intensity line item of going forward side by side based on the corresponding brightness value of current screen brightness; Wherein record this target brightness value, carry out on this this target brightness value basis of recording when adjusting for next brightness;
Step S250 according to this target brightness value, generates a brightness control signal;
Step 260 according to this brightness control signal, is determined the screen intensity of electronic equipment display part, finishes.
In other embodiment of the inventive method, if above-mentioned steps S230 judges this ambient light variable quantity
Do not surpass this detection threshold, namely
Smaller or equal to
It is also not obvious to illustrate that then ambient light changes, and does not satisfy default before brightness regularization condition, does not need to adjust the screen intensity of display device, keeps current screen brightness and gets final product.
Need to prove, the corresponding brightness value of screen intensity after adjusting each time, all record and adjust and constantly refresh according to each, so that follow-up adjustment all is to carry out, realized the memory mechanism that brightness is adjusted on the brightness value basis of recording;
Continue the testing environment illuminance value by the ALS sensor, realized the Sustainable Control to the display device screen intensity.
By method embodiment shown in Figure 2 as can be known, when ambient light changes not obvious (being that the ambient light variable quantity is no more than this default detection threshold), screen intensity can't be followed the variation of ambient light and be changed, brightness before screen is kept at this moment gets final product, and does not need to adjust.Comparatively fixing in ambient light, only a certain continue to change in more among a small circle in, compared to existing technologies, method embodiment shown in Figure 2, do not need frequently to adjust screen intensity, avoid ambient light to change the shake of screen intensity when little, and can prolong the serviceable life of screen, and saved system resource.Experience angle from the user, screen intensity can't frequently be glimmered, and meets user's use needs more.
Above-described embodiment is by the variable quantity of testing environment illuminance value
As trigger event, namely have only the surround lighting bigger change takes place, ALS brightness adjustment just can be worked, also solved ALS brightness in the prior art adjust scheme can not with the problem of brightness adjustment coexistence such as Fn hot key.Such as under stable ambient lighting condition, ALS brightness adjustment maintains a certain brightness with screen intensity, when the user is adjusted to another one brightness by the Fn function key with screen intensity, next sense cycle at ALS, system detects the ambient light value big variation does not take place, then can not make adjustment to screen intensity, make the result of brightness adjustment such as Fn function key be maintained and can this brightness be that follow-up brightness adjustment is carried out on the basis, realize the screen intensity memory mechanism.Since solved multiple brightness adjustment such as Fn function key in the existing ALS solution can't with the problem of ALS brightness adjustment coexistence, therefore also realized the coexistence mechanism that multiple brightness is adjusted.Based on the coexistence mechanism that this brightness is adjusted, the user can pass through correction screen intensitys such as Fn function key according to the hobby of oneself on the basis of enabling ALS brightness adjustment, adjust the problem that scheme can't be taken into account numerous user preferences thereby solved ALS brightness.
Fig. 3 is the schematic flow sheet of another embodiment of screen intensity method of adjustment of the present invention.As shown in Figure 3, this another embodiment mainly comprises the steps:
Step S310 by the ALS sensor, obtains an ambient light value A and storage under the current environment;
Step S320 according to the ambient light value A that stores, obtains the ambient light variable quantity in the certain hour scope
In the present embodiment, be by ALS sensor relatively second constantly T2 detect second environment illuminance value At2 and before detected first environment illuminance value At1 during at first moment T1, obtain this ambient light variable quantity
Step S330 judges this ambient light variable quantity
Surpass a default detection threshold
Namely
Greater than
This ambient light variable quantity
Surpass this detection threshold
It is comparatively violent to illustrate that ambient light changes, and may influence user's experience largely, and default brightness regularization condition before having satisfied need be made suitable adjustment so that the user obtains the information on the screen better;
Step S340, according to this ambient light value A under detected this current environment (also i.e. this second environment illuminance value At2), search default brightness curve or look-up table, based on the corresponding brightness value of a current screen brightness, obtain one for ALS target brightness value and the record of adjusting the display device screen intensity; Wherein record this ALS target brightness value, be used for next brightness adjustment, carry out on this this autonomous target brightness value basis of recording;
Step S350, detect in real time user input one from the subjective brightness adjustment information, illustrate that the user as required, initiatively screen intensity is adjusted, at this moment, accepted user input from the subjective brightness adjustment information, according to user's input from the subjective brightness adjustment information, obtain autonomous target brightness value and a record; And mode (namely temporarily not accepting the ALS target brightness value) is adjusted in temporary transient shielding ALS brightness before the user finishes this autonomous adjustment brightness; Wherein this autonomous target brightness value of record is used for adjusting from subjective brightness adjustment or ALS brightness by the user next time, carries out on this this autonomous target brightness value basis of recording;
Need to prove, this step detects the input from the subjective brightness adjustment information in real time, parallel with ALS brightness adjustment, also be this step S350 and aforementioned each step, not strict sequencing relation, at aforesaid step S310 between the step S340, execution in step S350 as required; In addition, herein from the subjective brightness adjustment information, be construed as the user from the brightness adjustment information of primary input, comprise the brightness adjustment information by various ways such as Fn function key, power source design setting, power management inputs;
Need to prove simultaneously, ALS adjusts or the autonomous corresponding brightness value of screen intensity afterwards of adjusting of user each time, all record also according to adjust and constantly refresh at every turn, so that follow-up adjustment all is to carry out, realized the memory mechanism that brightness is adjusted on the brightness value basis of recording;
Step S360 according to this autonomous target brightness value, generates an autonomous brightness control signal;
Step S370 according to this autonomous brightness control signal, determines the screen intensity of electronic equipment display part, finishes.
In other some embodiment of the inventive method, if above-mentioned steps S330 judges this ambient light variable quantity
Do not surpass this detection threshold, namely
Smaller or equal to
It is also not obvious to illustrate that then ambient light changes, do not satisfy default before brightness regularization condition, do not need to adjust the screen intensity of display device, keep current screen brightness, detecting during from the subjective brightness adjustment information of user input, adjust screen intensity according to this from the subjective brightness adjustment information.
Continue the testing environment illuminance value by the ALS sensor, the active adjustment in conjunction with user function key has realized the Sustainable Control to the display device screen intensity.
By this another embodiment shown in Figure 3 as can be seen, this another embodiment not only carries out the real-time adjustment of screen intensity according to the ambient light variable quantity, and can also manually adjust according to the brightness adjustment information that the user imports by brightness such as function key adjustment mode, having overcome in the prior art ALS brightness adjusts mode and adjusts the defective that mode can not be served for the user in phase with function key brightness, can not produce as situations such as brightness jitters of the prior art, improve user service experience, the problem of program code confusion more can not occur.
The various embodiments of the inventive method are by the variable quantity of testing environment illuminance value
As trigger event, if
Greater than the threshold value that sets in advance
Think that then bigger change has taken place ambient light, thereby trigger interrupt event, reporting system is adjusted the brightness of screen.Avoided the total ALS brightness of prior art to adjust solution and disturbed because of being subject to of bringing of real-time, the screen intensity shake is adjusted in real time and is accelerated screen aging reduction of service life, and causes problem such as power consumption increase.
