To obtain the mediation brightness of bright pixel 1311；And
S3, regulates bright pixel 1311 to being in harmonious proportion brightness.
The control device 110 of embodiment of the present invention includes detection module 111, computing module 112 and adjustment module 113,
Can be respectively used to realize S1, S2 and S3.It is to say, detection module 111 is used for detecting brightness more than predetermined brightness value
Mistake bright pixel 1311, computing module 112 is for being multiplied by the difference of the brightness and predetermined brightness value of crossing bright pixel 1311
Pre-determined factor adds predetermined brightness value to obtain the mediation brightness of bright pixel 1311, adjustment module 113 for incited somebody to action
Bright pixel 1311 regulates to being in harmonious proportion brightness.
Incorporated by reference to refering to Fig. 3, in some embodiments, electronic installation 100 includes mobile phone or panel computer.Electronics fills
Put 100 and can include light sensor 150 or imaging device 170, be used for sensing ambient brightness.Imaging device 170 is permissible
It it is photographic head.
When the display screen 130 of the electronic installations such as mobile phone 100 shows, regional area brightness usually can be run into too high and twinkling
Situation.If the overall brightness of regulation display screen 130, it is easily caused again overall display partially dark, so that Consumer's Experience is bad,
And be unfavorable for protecting eyes.
In embodiments of the present invention, only regulation brightness exceedes the mistake bright pixel 1311 of predetermined brightness value, so that crossing clear zone
The brightness in territory lowers, and does not affect the brightness of non-overly bright region, thus is reducing the area of regulation luminance area as far as possible
On the premise of the display of display screen 130 is adjusted, and protect the eyes of user.So, on the one hand eye protection, another
Aspect avoids the most dark region to cross dark and affect user and watch display content.
Referring to Fig. 4, such as, predetermined brightness value is 50, and adjustment factor is 0.4, then brightness is the mistake bright pixel of 100
1311, become (100-50) * 0.4+50=70 after regulation.
In some embodiments, predetermined brightness value inputs setting according to user.Owing to different user is to highlighted adaptation journey

Family oneself input sets predetermined brightness value.Such as arranging the adjustment bar about predetermined brightness value, user can be slided by finger
Adjustment bar regulates the size of predetermined brightness value, predetermined brightness value can be tuned up when ambient brightness is brighter, at ambient brightness
Time dark, predetermined brightness value is turned down.
Referring to Fig. 5, in some embodiments, predetermined brightness value obtains according to ambient brightness.
Such as, using the ambient brightness that senses as predetermined brightness value.Such as ambient brightness is 50, therefore predetermined brightness value
Being set to 50, adjustment factor is 0.4, then brightness is the mistake bright pixel 1311 of 100, becomes (100-50) after regulation
* 0.4+50=70.
The size of the pupil of human eye is to change along with the change of the ambient brightness in the visual field.The such as brightness in the visual field
Time relatively low, the platycoria of people, if now the brightness of display screen 130 is too high, the stimulation that human eye is stronger can be given, cause people
Eye is uncomfortable, namely " dazzles ".Therefore, the size of predetermined brightness value can be determined according to ambient brightness, regulate process intelligence
Energy, convenience, to the experience that user is good, and contribute to eye protection.
Incorporated by reference to refering to Fig. 3, the mode obtaining ambient brightness has multiple, and such as, in some embodiments, electronics fills
Putting 100 and include light sensor 150, ambient brightness is obtained by light sensor 150.Light sensor 150 is hands
The device of wide use on the electronic installations such as machine 100.
Incorporated by reference to refering to Fig. 3, in addition to using light sensor 150, in some embodiments, electronic installation 100
Including imaging device 170, imaging device 170 is for obtaining the image of environment, and ambient brightness is by calculating the brightness of image
Value obtains.
Such as, the ambient image of shooting can transfer HSL form to obtain the brightness value of each pixel, then by all pictures
The added luminance of element is averaged, using this average as ambient brightness.The ambient image of photographic head shooting can contain broader
Field range, therefore available more objective ambient brightness.
Additionally, due to shooting single image, it is possible to because fortuitous event causes the brightness of image untrue objective, such as hands
Refer to or other article imprudences have blocked photographic head, or owing to shake causes image fault etc..Therefore multiframe figure can be shot
Picture, asks the meansigma methods of average brightness value of every two field picture as mean flow rate.Further, can carry out in multiple image
Screening, the image (being likely to be caused by above-mentioned fortuitous event) that such as Trimmed mean brightness value is too high or too low, then with remaining
Image calculate mean flow rate.So, available result more reasonable, objective.
Can also comprehensively use light sensor 150 and imaging device 170 etc., even can use multiple imaging device simultaneously
170, use front-facing camera and post-positioned pick-up head the most simultaneously, thus sensing ambient brightness is the most comprehensive from different angles
Calculate to obtain more objective ambient brightness.
The control method of embodiment of the present invention can trigger under certain conditions.Such as, in some embodiments, S1
Difference in display screen 130 brightness with predetermined brightness value triggers when being more than predetermined value, and carries out S2 and S3 subsequently.
In the control device of some embodiment, detection module 111 is in the difference of display screen 130 brightness Yu predetermined brightness value
Value triggers more than during predetermined value.
Display screen 130 brightness refers to the overall brightness of display screen 130, owing to predetermined brightness value is to crossing bright pixel 1311
Carry out the foundation judging and regulating, and it is the most relevant with display screen 130 brightness to cross bright pixel 1311, the most also can be by predetermined
Brightness value compared with display screen 130 brightness with judge whether trigger embodiment of the present invention control method.Display screen
The difference of 130 brightness and predetermined brightness value can be on the occasion of, negative value or zero.
Judging that display screen 130 brightness difference with predetermined brightness value is more than predetermined value, say, that judging display screen
When 130 brightness are too high, trigger the detection of S1.So, can according to display screen 130 brightness intelligent trigger control method with
Regulation brightness.
In conjunction with some embodiment, predetermined brightness value can be inputted by user or ambient brightness determines.If being determined by ambient brightness,
When being then equivalent to judge that display screen 130 brightness is too high according to ambient brightness, trigger S1 and subsequent step, thus can give and use
The experience of family hommization.
Control method also can input triggering according to user, and in some embodiments, S1 inputs triggering according to user.?
In the control device of some embodiment, detection module 111 inputs triggering according to user.
Such as, the virtual key about brightness Intelligent adjustment is set, triggers when user clicks on, or defeated according to user
S1 is triggered when entering to enter Intelligent adjustment pattern.So, user's demand to brightness regulation can preferably be met.
Control method also can continuously open Time Triggered according to display screen 130, such as, in some embodiments, and S1
Trigger when the time that continuously opens of display screen 130 reaches the scheduled time.In the control device of some embodiment, inspection
Survey module 111 to trigger when the time that continuously opens of display screen 130 reaches the scheduled time.
Such as, the electronic installations such as mobile phone 100 display screen 130 grow to certain time when continuously opening, the most automatically enter
Enter Intelligent eyeshield pattern, and produce.When continuously opening the time of display screen 130 of calculating, of short duration during unlatching for a long time
Pass screen can ignore.So, user can be alleviated and watch display screen 130 for a long time and the eye strain that produces.
Control method also can trigger according to ambient brightness, and in some embodiments, S1 is in the fall of ambient brightness
Trigger more than during predetermined amplitude.In the control device of some embodiment, detection module 111 is in the decline of ambient brightness
Amplitude triggers more than during predetermined amplitude.
The most with good grounds ambient brightness of electronic installation 100 such as the most a lot of mobile phones are automatically adjusted the function of display screen 130 brightness,
Such as also display screen 130 brightness is dimmed when sensing ambient brightness and being dimmed.Assume under brighter ambient brightness,
Display screen 130 brightness is adjusted to brighter state, if now ambient brightness declines to a great extent, can trigger control method to incite somebody to action
High region dims, thus protects the vision of user.
The mode obtaining ambient brightness includes using light sensor 150 to sense, use imaging device 170 acquisition etc., can
With reference to ambient brightness acquisition side corresponding in above-mentioned some embodiment obtained according to ambient brightness about predetermined brightness value
The description of formula, is not described in detail in this.
Referring to Fig. 6-7, in some embodiments, control method includes after S1:
S4, it is judged that mistake bright pixel 1311 accounts for whether the ratio of all pixels is more than predetermined ratio, if so, carries out S2.
S4 can be realized by the judge module 114 controlling device 110 of some embodiment.I.e. judge module 114 is used for
Judged that bright pixel 1311 accounted for the ratio of all pixels whether more than predetermined ratio and trigger computing module when being judged as YES
112。
It is to say, if the quantity crossing bright pixel 1311 is too much, the brightest viewing area is excessive, then control
Brightness regulation in method processed；And if negligible amounts, then can not be adjusted, because the impact on eyes of user is limited.
So, can be with intelligent decision, the brightness regulation of in good time trigger control method.
After triggering first and having carried out S1, S2, S3, owing to the display content of display screen 130 is real-time in the case of a lot
Change, say, that the brightness of each pixel it could also be possible that be continually changing, therefore take certain methods or step with
Display screen 130 is made to be maintained at the state of eye protection.
Such as, in some embodiments, S1 detection brightness is triggered during control method Real-time more than predetermined brightness value
Cross bright pixel 1311.In some embodiments, when controlling device Real-time, detection trigger module 111 detects brightness and is more than
The mistake bright pixel 1311 of predetermined brightness value.
Owing to the display content of display screen 130 is real-time change in the case of a lot, say, that the brightness of each pixel is also
It is likely to be and is continually changing, therefore need to detect crossing bright pixel 1311 in real time, and to new mistake bright pixel 1311
It is adjusted.So, display screen 130 just can be made to be maintained at eye protection state.
And for example, referring to Fig. 8-9, in some embodiments, control method includes after S3:
S5, triggers S1 when the display content of display screen 130 changes.
S5 can be realized by first trigger module 115 controlling device 110 of some embodiment, the i.e. first trigger module
115 for the detection trigger module 111 when the display content of display screen 130 changes.
As a example by mobile phone or panel computer, a lot of in the case of the display content not real-time change of display screen 130, such as
When user uses reading application program, news client, phone and note, it is usually when user has operated, aobvious
The content shown just can change, and generally display content is static.In fact, during except playing video and game, its
In the case of the remaining overwhelming majority, the change of display content is the most non real-time, the most infrequently, and therefore can be in the display of display screen 130
The brightness regulation of trigger control method when content changes, detected bright pixel 1311 and the most again to crossing bright pixel
1311 are adjusted.
So, according to the change triggers control method of display content, both can meet the eye protection needs of user, system can be simplified again
The workload of system and power consumption so that it is carry out brightness regulation the most in good time.
Can be changed by the brightness value of detection pixel, or by the operation signal of detection user to judge to show whether content is sent out
Changing.Additionally, also whether can switch to decide whether according to current application program (APP) or application interface
Produce and trigger signal with trigger control method.
The most in some embodiments, referring to Figure 10-11, control method includes after S3:
S5a, triggers S1 detecting when user switches application program or application interface.
S5a can be realized by the second trigger module 115a controlling device 110 of some embodiment, the i.e. second trigger module
115a is for the detection trigger module 111 when detecting that user switches application program or application interface.
Application interface can refer to the different interfaces of application program, such as certain social platform APP, it may include chat interface, friend
Friend list interface, address list interface, interface etc. is set；Application interface can also refer to that system carries the different interfaces of function,
Such as SMS interface, dialing phone interface, system arrange interface etc..When display screen 130 shows that content is from one
When APP is switched to another APP, or when an application interface is switched to another application interface, show content
Can change, the brightness of each pixel also can change, and therefore preferably trigger control method was again to enter bright pixel 1311
Detect and regulate.Detection simple possible to application program or application interface.
In some embodiments, display screen 130 includes self light emitting display panel 130；Pel array 131 includes point source
Array.
Such as, in some embodiments, self light emitting display panel 130 includes OLED display screen 130.
OLED (Organic Light-Emitting Diode) has self luminous characteristic, and therefore OLED display screen 130 can
Realize pointolite array, carry out point of adjustment light-source brightness by controlling the brightness of each point source.Additionally, OLED display screen
130 have the advantages such as thickness is thin, it is good to do pinking, viewing visual angle is wide, response is rapid, luminous efficiency is high, bent.
Regulating display screen 130 brightness by the brightness of control point light source, control more direct, response is fast.By regulating
The brightness of bright spot light source, can realize eye protection effect.
Pre-determined factor determines the amplitude of accommodation crossing bright pixel 1311, and pre-determined factor is typically greater than equal to 0 and less than 1
Number.If pre-determined factor is 0, be equivalent to directly be adjusted to predetermined brightness value by crossing bright pixel 1311, if pre-determined factor is 1,
Be equivalent to not carry out any regulation.Pre-determined factor is the least, and the amplitude of regulation is the biggest.
Referring to Figure 12-14, in some embodiments, control method includes:
S6, detection regulation rank also determines pre-determined factor according to regulation rank.
S6 can be realized by the control device 110 of some embodiment cover half block 116 really, i.e. determine module 116 for
Detection regulation rank also determines pre-determined factor according to regulation rank.
In some embodiments, regulation rank inputs setting according to user.
Such as, regulation rank is divided into slightly, moderate, severe, and pre-determined factor corresponding respectively is 0.7,0.4,0.1.False
If predetermined brightness value is 50, and certain brightness value crossing bright pixel 1311 is 100, then in slight, moderate, severe regulation
Result adjusted under rank is respectively as follows:
(100-50) * 0.7+50=85；
(100-50) * 0.4+50=70；
(100-50) * 0.1+50=55
Visible, pre-determined factor is the least, and the brightness after regulation is the least, closer to predetermined brightness value.And different regulation ranks is corresponding
Different pre-determined factor, thus the individual demand of user can be met.Regulation rank, also can be according to user except can be in addition to user inputs
The user profile such as age, user health situation carry out Intelligent adjustment or switching, thus better adapt to the particular case of user and enter
Row brightness regulation.
In some embodiments, adjustment factor determines according to the brightness crossing bright pixel 1311；Cross the bright of bright pixel 1311
Spending the biggest, adjustment factor is the least.
It is to say, the adjustment factor of different mistake bright pixel 1311 correspondences can be different, the size of adjustment factor and mistake
The brightness of bright pixel 1311 is relevant.Owing to too high pixel intensity is the highest, the injury to eye is the biggest, the most preferably uses less
Adjustment factor.So, can be adjusted for the different situations crossing bright pixel 1311, thus contribute to realizing eye protection purpose.
Refer to Figure 15, additionally, also segmentation can be used to be multiplied by different adjustment factors for crossing the brightness of bright pixel 1311
Mode regulate brightness, such as bigger luminance factor is multiplied by for relatively low brightness section, higher brightness section is taken advantage of
With less luminance factor.
Such as, predetermined brightness value is 50, for crossing the bright pixel 1311 luminance part more than 50, the brightness section of 50～70
The brightness section coefficient of correspondence 0.3 of corresponding brightness coefficient 0.7, more than 70.
Then for the mistake bright pixel 1311 that brightness is 65, the brightness value after its regulation is:
