It is camera.
When the display screen 130 of the electronic devices such as mobile phone 100 is shown, it is excessively high and twinkling usually to encounter regional area brightness
The case where.If the overall brightness of display screen 130 is adjusted, and it is partially dark to easily lead to whole display, to keep user experience bad, and not
Conducive to protection eyes.
In embodiments of the present invention, the mistake bright pixel 1311 that brightness is more than predetermined brightness value is only adjusted, to make bright
The brightness in region lowers, the brightness without influencing non-overly bright region, thus reducing the area for adjusting luminance area as far as possible
Under the premise of the display of display screen 130 is adjusted, and protect the eyes of user.In this way, one side eyeshield, on the other hand keeps away
Exempt from natively darker region secretly influences user and watches display content excessively.In addition, different adjusting ranks correspond to it is different pre-
Determine coefficient, that is, correspond to different strength of adjustment, in this way, different adjusting ranks can be used with more for different situations
Accurately meet the eyeshield and viewing demand of user.
Referring to Fig. 4, corresponding pre-determined factor is 0.7,0.4,0.1 for example, adjusting rank is divided into weak, medium, strong.
Assuming that predetermined brightness value be 50, and certain cross bright pixel 1311 brightness value be 100, then weak, medium, strong adjust rank under to its into
The result that row is adjusted is respectively as follows:
(100-50) * 0.7+50=85；
(100-50) * 0.4+50=70；
(100-50) * 0.1+50=55
Pre-determined factor determines that, to the amplitude of accommodation for crossing bright pixel 1311, pre-determined factor is typically greater than equal to 0 and less than 1
Number.If pre-determined factor is 0, bright pixel 1311 will be crossed by, which being equivalent to, is directly adjusted to predetermined brightness value, if pre-determined factor is 1, quite
In not carrying out any adjusting.Pre-determined factor is smaller, and the amplitude of adjusting is bigger.
Pre-determined factor is smaller, and the brightness after adjusting is smaller, closer to predetermined brightness value.And different adjusting ranks is corresponding not

In some embodiments, each to cross the corresponding independent adjustment factor of bright pixel 1311, adjustment factor is according to excessively bright
The brightness of pixel 1311 determines；The brightness for crossing bright pixel 1311 is bigger, and adjustment factor is smaller.
That is, the different corresponding adjustment factors of mistake bright pixel 1311 can be different, the size of adjustment factor
It is related with the brightness of bright pixel 1311 is crossed.It is also bigger to the injury of eye since excessively high pixel intensity is higher, thus preferably use compared with
Small adjustment factor.In this way, the different situations that can be directed to bright pixel 1311 are adjusted, to help to realize eyeshield mesh
's.
There are many determining governing stage otherwise, for example, Fig. 5-6 is please referred to, in some embodiments, control method packet
: S05 is included to be inputted according to user and determine adjusting rank.
S05 can be realized by the input module 115 of the control device 110 of certain embodiments.That is, input module
115 determine adjusting rank for inputting according to user.
In this way, user can be according to scene instantly and the suitable adjusting rank of self-demand setting.For example, eyes of user is with strong
Light is more sensitive, can emphasize that assistant warden is other by inputting setting, lower the brightness of bright pixel 1311, significantly to protect eyesight.
For another example, Fig. 7-8 is please referred to, in some embodiments, control device 110 includes:
S06 determines adjusting rank according to the time that continuously opens of display screen 130.
S06 can be realized by the first level determining module 116 of the control device 110 of certain embodiments.That is first level
Determining module 116 is used to determine adjusting rank according to the time that continuously opens of display screen 130.
For example, the display screen 130 in the electronic devices such as mobile phone 100 grew to for the first predetermined time when continuously opening, i.e., from
It is dynamic to enter low adjustment rank, enter when continuously opening duration and reaching for the second predetermined time in adjust rank, when continuously opening
Enter when length reaches the third predetermined time and emphasizes that assistant warden is other.First predetermined time, the second predetermined time, third predetermined time can divide
It Wei not be 1 hour, 1.5 hours, 2 hours.When continuously opening the time of display screen 130 is being calculated, it is of short duration during opening for a long time
Closing screen can ignore.In this way, can be relieved the eye strain that user watches display screen 130 for a long time and generates, and can be with fatigue program
Increase reinforce strength of adjustment.
For another example, Fig. 9-10 is please referred to, in some embodiments, control method includes:
S07 is determined according to age of user and is adjusted rank.
S07 can be realized that is, second level determining module 117 is used by the second level determining module 117 of certain embodiments
Rank is adjusted in determining according to age of user.
Age of user can be inputted by user, such as the typing of setting userspersonal information, include in personal information the age this
One.For example, system identification should when user is when the age of system input (or being inputted by parent for child) personal information is 9
User is children.The eyes of children are in the puberty, need stronger protection, therefore, can set stronger adjusting rank to protect
Protect children's vision.In this way, keeping the display of electronic device 100 more intelligent and humanized, and eyeshield can be carried out for different crowd.
In addition to being actively entered, certain features of identification user also can be used in a manner of judging age of user.Please refer to figure
11-12, in some embodiments, electronic device 100 include the image acquiring device 170 for obtaining user's facial image；
Control method includes:
S08 identifies facial image to judge age of user.
S08 can be realized by the identification module 118 of the control device 110 of certain embodiments.I.e. identification module 118 is for knowing
Others' face image is to judge age of user.
Conventional images processing technique can identify face in the picture, and identify the face, wrinkle, skin of user's face
The features such as skin exquisiteness degree can carry out rough judgement according to age of these features to user, and be produced according to the age of user
Raw trigger signal, i.e., carry out targeted brightness regulation to the age.
For example, can refer to the embodiment of above-mentioned " user's input can be age of user ", when judging user for children
Corresponding brightness regulation is carried out to protect user's eyesight.
In this way, electronic device 100 can carry out judgement to age of user automatically to carry out the view to match with other ages
Shield of trying hard to keep has preferable application value when the user of electronic device 100 may be multiple.For example, there is the adult of child
Year usually worries that the child of oneself is excessively affected vision using the cell phone entertainment of oneself, if electronic device 100 uses this implementation
The control method of mode can automatically adjust brightness of display screen, to protect child's eyesight when child uses mobile phone.
In addition, settable range sensor, the distance of face is arrived for sensing camera or electronic device 100, according to arriving
The distance of face can and facial image in the size of face face size can be scaled to the size of gauged distance human face, then with
The standard faces size of the people of all age group compares (difference in size of children and adult face is larger) under gauged distance,
The corresponding age bracket of the user is allotted, to can determine whether that the user is children or adult.
Figure 13-14 is please referred to, in some embodiments, control method includes:
S09 determines regulations speed according to rank is adjusted；
Reconciliation brightness is adjusted to for bright pixel 1311 is crossed with regulations speed in S04.
In some embodiments, control device 110 includes rate determination module 119, and for realizing S09, i.e. rate is true
Cover half block 119 is used to determine regulations speed according to adjusting rank.The adjustment module 114 of control device 110 is also used to adjust speed
Rate is adjusted to reconciliation brightness for bright pixel 1311 is crossed.
Regulations speed refers in the unit time to the brightness value for crossing the adjusting of bright pixel 1311.That is, different governing stages
Different regulations speeds can not corresponded to.For example, often needing when it is strong for adjusting rank to the biggish brightness value of excessively high pixel adjustment
Therefore faster regulations speed can be not arranged to guarantee that 130 brightness of display screen can be when relatively short for assistant warden is emphasized in amplitude
Interior adjustment finishes.In this way, adjusting to the reconciliation brightness for eyeshield as early as possible, help to protect user's eyesight.
In some embodiments, predetermined brightness value is inputted according to user and is set.Since different user is to highlighted adaptation
Degree is different, the adaptation program of different environment or venue users to brightness may also be different, therefore can set by with
Family oneself input setting predetermined brightness value.Such as the adjustment bar about predetermined brightness value is set, user can be slided by finger and be adjusted
Item is saved to adjust the size of predetermined brightness value, can be tuned up predetermined brightness value when ambient brightness is brighter, it is darker in ambient brightness
When predetermined brightness value is turned down.
Figure 15-17 is please referred to, in some embodiments, control method includes:
S11 obtains ambient brightness；And
S12 determines predetermined brightness value according to ambient brightness.
S11 and S12 can be respectively by the acquisition module 121 of the control device of certain embodiments 110 and brightness determining module
122 realize, i.e., acquisition module 121 is used to be determined according to ambient brightness predetermined for obtaining ambient brightness, brightness determining module 122
Brightness value.
Figure 17 is please referred to, for example, using the ambient brightness sensed as predetermined brightness value.Such as ambient brightness is 54, because
This predetermined brightness value is set to 54, if under middle adjusting rank, adjustment factor 0.4, then the mistake bright pixel 1311 that brightness is 100,
Become (100-54) * 0.4+50=68.4 after adjusting.
The size of the pupil of human eye is to change with the variation of the ambient brightness in the visual field.Such as it is bright in the visual field
When spending lower, the pupil of people amplifies, if the brightness of display screen 130 is excessively high at this time, can give the stronger stimulation of human eye, lead to human eye not
It is comfortable, that is, " twinkling ".Therefore, the size of predetermined brightness value can be determined according to ambient brightness, adjustment process intelligence, conveniently,
It gives user good experience, and facilitates eyeshield.
Fig. 3 is please referred to, there are many modes for obtaining ambient brightness, for example, in some embodiments, electronic device
100 include light sensor 150, and ambient brightness is obtained by light sensor 150.Light sensor 150 is the electronics such as mobile phone
The wide device used on device 100.
Fig. 3 is please referred to, other than using light sensor 150, in some embodiments, electronic device 100 is wrapped
Image acquiring device 170 is included, image acquiring device 170 is used to obtain the image of environment, and ambient brightness is by calculating the bright of image
Angle value obtains.
For example, the ambient image of shooting can be switched to HSL format to obtain the brightness value of each pixel, then by all pixels
Added luminance average, using the mean value as ambient brightness.The ambient image of camera shooting can cover broader view
Wild range, therefore more objective ambient brightness can be obtained.
Further, since shooting single image, it is possible to because fortuitous event causes the brightness of image untrue objective, such as hand
Refer to or other articles have accidentally blocked camera, or since shake leads to image fault etc..Therefore can shoot multi-frame images,
Ask the average value of the average brightness value of every frame image as average brightness.Further, it can be screened in multiple image, example
It is calculated as the too high or too low image of Trimmed mean brightness value (is likely to be caused by above-mentioned fortuitous event), then with remaining image
Average brightness.In this way, more reasonable, objective result can be obtained.
It can also integrate using light sensor 150 and image acquiring device 170 etc., or even multiple images can be used simultaneously
Acquisition device 170, such as front camera and rear camera are used simultaneously, to sense ambient brightness simultaneously from different angles
COMPREHENSIVE CALCULATING is to obtain more objective ambient brightness.
Figure 18-19 is please referred to, the control method of embodiment of the present invention can trigger under certain conditions.For example, at certain
In a little embodiments, control method includes:
S11 obtains ambient brightness；And
S13, judges whether the fall of ambient brightness is greater than predetermined amplitude and triggers S01 when being judged as YES.
S11 and S13 can be real by the acquisition module 121 of the control device of certain embodiments 110 and judgment module 123 respectively
Existing, i.e., acquisition module 121 is for obtaining ambient brightness, and judgment module 123 is for judging whether the fall of ambient brightness is big
In predetermined amplitude and the detection trigger module when being judged as YES.
The function of all with good grounds ambient brightness automatic adjustment 130 brightness of display screen of the electronic devices 100 such as many mobile phones at present,
Such as sense ambient brightness it is dimmed when also 130 brightness of display screen is dimmed.Assuming that will be shown under brighter ambient brightness
130 brightness of display screen is adjusted to brighter state, if ambient brightness declines to a great extent at this time, can trigger control method so that brightness is excessively high
Region dims, to protect the eyesight of user.
The mode for obtaining ambient brightness includes obtaining using the sensing of light sensor 150, using image acquiring device 170
Deng can refer to corresponding ambient brightness in the above-mentioned certain embodiments obtained about predetermined brightness value according to ambient brightness and obtain
The description of mode, this will not be detailed here.
Control method can also be inputted according to user and be triggered, and in some embodiments, S1 is inputted according to user and triggered.At certain
In the control device 110 of a little embodiments, detection module is inputted according to user and is triggered.
For example, the virtual key that setting is intelligently adjusted about brightness, is triggered when user clicks, or defeated according to user
Enter and triggers S1 when entering intelligent shaping modes.In this way, can preferably meet the needs of user is to brightness regulation.
Control method can also continuously open time trigger according to display screen 130, for example, in some embodiments, S1
Display screen 130 continuously open the time reach the predetermined time when triggering.In the control device 110 of certain embodiments, inspection
Survey module display screen 130 continuously open the time reach the predetermined time when triggering.
For example, the display screen 130 in the electronic devices such as mobile phone 100 grows to certain time when continuously opening, i.e., automatically into
Enter intelligent eyeshield mode, and generates.When continuously opening the time of display screen 130 is being calculated, of short duration pass during opening for a long time
Screen can be ignored.In this way, can be relieved the eye strain that user watches display screen 130 for a long time and generates.
In some embodiments, control method judged that bright pixel 1311 accounted for the ratios of all pixels and is after S01
It is no to be greater than predetermined ratio, if so, carrying out S02.
That is, excessively bright display area is excessive in other words, then is controlled if the quantity for crossing bright pixel 1311 is excessive
Brightness regulation in method；And if negligible amounts, can without adjust because the influence to eyes of user is limited.In this way,
It can be with intelligent decision, the brightness regulation of in due course trigger control method.
After triggering has carried out S01, S02, S03 and S04 for the first time, due to the display content of display screen 130 in many cases
It is real-time change, that is to say, that the brightness of each pixel takes certain methods or step it could also be possible that continually changing
Suddenly so that display screen 130 is maintained at the state of eyeshield.
For example, in some embodiments, control method triggers S1 detection brightness in real time and is greater than the excessively bright of predetermined brightness value
Pixel 1311.In some embodiments, the real-time detection trigger module of control device 110 detection brightness is greater than predetermined brightness value
Cross bright pixel 1311.
Since the display content of display screen 130 in many cases is real-time change, that is to say, that the brightness of each pixel
It could also be possible that continually changing, therefore need detect to crossing bright pixel 1311 in real time, and to new mistake bright pixel 1311 into
Row is adjusted.In this way, just display screen 130 can be made to be maintained at eyeshield state.
For another example, Figure 20-21 is please referred to, in some embodiments, control method includes: after S04
S14 triggers S01 when the display content of display screen 130 changes.
S14 can be realized that is, trigger module 124 is used for aobvious by 110 trigger module 124 of control device of certain embodiments
Detection trigger brightness is greater than the module of the mistake bright pixel 1311 of predetermined brightness value when the display content of display screen 130 changes.
By taking mobile phone or tablet computer as an example, the display content of display screen 130 is not real-time change in many cases, such as
When user is using application program, news client, phone and short message is read, usually when user has operated, display
Content can just change, and usually display content is static.When in fact, in addition to playing video and game, remaining exhausted big portion
In the case of point, shows the variation of content and non real-time, also infrequently, therefore can change in the display content of display screen 130
When trigger control method brightness regulation, i.e., detected again bright pixel 1311 and to cross bright pixel 1311 be adjusted.
In this way, can not only meet the eyeshield needs of user, but also can simplify and be according to the change triggers control method of display content
The workload and power consumption of system make it only carry out brightness regulation in due course.
It can be changed by the brightness value of detection pixel, or the operation signal by detecting user is to judge whether show content
It changes.In addition, whether can also be switched according to current application program (APP) or application interface to decide whether to generate
Trigger signal is with trigger control method.
Control method is included in after S4 in some embodiments detects that user switches application program or using boundary
S01 is triggered when face.
Application interface can refer to the different interfaces of application program, such as certain social platform APP, it may include chat interface, friend
Friendly list interface, address list interface, set interface etc.；Application interface can also refer to that system carries the different interfaces of function, such as
