Photographic head.
The ambient image of shooting can transfer HSL form to obtain the brightness value of each pixel 1313, then by all pixels
The added luminance of 1313 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 can shoot multi-frame images,
Ask the meansigma methods of average brightness value of every two field picture as mean flow rate.Further, can screen in multiple image, example
Image (being likely to be caused by above-mentioned fortuitous event) as too high or too low in Trimmed mean brightness value, then calculate with remaining image
Mean flow rate.So, available result more reasonable, objective.
Refer to Fig. 6-7, determine that in the embodiment of object brightness, control method includes at some according to ambient brightness:
S4, arranges the relational expression of ambient brightness and object brightness；Object brightness is determined by relational expression.
S4 can be realized by the module 114 that arranges controlling device 110 of some embodiment.Module 114 is set for arranging
Ambient brightness and the relational expression of object brightness；Object brightness is determined by relational expression.Ambient brightness can by light sensor 150 or
Imaging device 170 records.
In general object brightness and ambient brightness should be positively related relations, say, that the ambient brightness sensed is more
Bright, object brightness the most correspondingly should lighten, and ambient brightness is the darkest, and object brightness is the most correspondingly adjusted the darkest.Some embodiment party
In formula, object brightness can be equal to ambient brightness.Or, it is bright that the relational expression of ambient brightness and object brightness, such as target can be set
Spend and be multiplied by a default coefficient for ambient brightness, or object brightness is that ambient brightness adds a default value, then or
There is more complicated relation examination etc..
By the setting of relational expression, more reasonably relation can be obtained between object brightness and ambient brightness, thus according to ring
Border brightness obtains object brightness preferably, to promote user's physical ability.
Referring to Fig. 8-9, in some embodiments, brightness flop value is fixed, and determines that step includes:
S101, calculates the difference between object brightness and brightness of display screen；And
S102, determines progression according to difference and brightness flop value.
In some embodiments, control device 110 cover half block 111 really and include that calculating sub module 1111 and first determines
Submodule 1112, can be respectively used to realize S101 and S102.I.e. calculating sub module 1111 is used for calculating object brightness and display screen
Difference between brightness.First determines that submodule 1112 is for determining progression according to difference and brightness flop value.
According to relational expression (1), when difference and brightness flop value (the brightness flop value of i.e. every grade regulation) determine, namely
L1-L0 and △ L determines, so that it may calculate progression.Such as difference is 50, and brightness flop value is 2, then determine therefrom that progression is 50/2
=25.
In some cases, in order to make human eye seem, the brightness flop of display screen 130 smooths, flicker free sense, and brightness becomes
Change value can be fixed as a relatively small value.And progression is unfixed, relevant with difference to be regulated.Difference is the biggest, level
Number is the biggest, and vice versa.The brightness flop that so can ensure display screen 130 is smooth, and human eye seems comfortable, contributes to
Eye protection.
In some embodiments, the duration of every grade of regulation can be fixing.If fixing, then no matter difference is how many,
The rate of change of brightness (the brightness flop amplitude of unit interval) of human eye viewing is fixing, so that human eye feels comfortably cool.
The duration of every grade of regulation can be unfixed, such as, automatically adjusted by every grade of duration regulated when progression is excessive
Short, so that total duration is unlikely to long, to avoid, user is long when regulating brightness of display screen to be waited.Such as can arrange one
Individual total duration upper limit, if progression is too much, then total duration is set to total duration upper limit, and calculates every grade of regulation according to total duration and progression
Duration.
In some embodiments, duration determines according to progression, and progression is the most, and duration is the shortest.
Referring to Figure 10-11, in some embodiments, progression is fixed, and S1 includes:
S101, calculates the difference between object brightness and currently displaying screen brightness；And
S103, determines brightness flop value according to difference and progression.
S101 and S103 can be determined by the calculating sub module 1111 and second controlling device 110 of some embodiment respectively
Submodule 1113 realizes.I.e. calculating sub module 1111 is for calculating the difference between object brightness and currently displaying screen brightness.The
Two determine that submodule 1113 is for determining brightness flop value according to difference and progression.
According to relational expression (1), when difference and progression determine, and namely L1-L0 and N determines, so that it may calculate brightness and become
Change value (the brightness flop value of i.e. every grade regulation) △ L.Such as difference is 50, and progression is 10, then determine therefrom that brightness flop value is
50/10=5.
In some embodiments, in order to make user need not wait long time, progression and every grade when regulating brightness
The duration of regulation is fixing.Such as when entering into bright ring border from dark situation, brightness of display screen need to be transferred to one brighter
Value.Such as, the brightness value from 100 is adjusted to 160, and progression is fixed as 10, then the brightness flop of every grade of regulation is 6；And if from 100
Brightness value is adjusted to 200, and progression is still 10, then the brightness flop of every grade of regulation is 10.If every grade regulation time a length of 0.2 second, then
The difference no matter regulated is much, and total duration is 0.2 × 10=2 second.
Or in some embodiments, the duration of every grade of regulation is unfixed, but become with every grade of brightness regulated
Change value is relevant, such as, be proportionate.Brightness flop value is the biggest, and the duration of every grade of regulation is the longest, so, can present on the whole
Rate of change of brightness at human eye is relatively stable or fixing, thus avoids human eye not feel well.
Referring to Figure 12-14, in some embodiments, S2 regulates the bright of each pixel 1313 in the way of packet timesharing
Degree.The i.e. adjustment module 112 controlling device 110 of some embodiment regulates each pixel 1313 in the way of packet timesharing
Brightness.
Such as, in some embodiments, display screen 130 is formed with multiple pixel groups 1311, and each pixel groups 1311 is wrapped
Include equal number of multiple pixel 1313；Control method includes:
S5, calculates the difference between object brightness and brightness of display screen；
S6, determines the brightness value of every grade of regulation of each pixel 1313 according to difference and progression；
S2 regulates each pixel 1313 of pixel groups 1311 the most successively according to the brightness value of progression and every grade of regulation.
S5, S6, S2 can be determined mould by the control computing module 115 of device 110 of some embodiment, pixel 1313 respectively
Block 116 and adjustment module 112 realize.It is to say, computing module 115 is for calculating between object brightness and brightness of display screen
Difference.Pixel 1313 determines that module 116 for determining the brightness value of every grade of regulation of each pixel 1313 according to difference and progression.Adjust
Joint module 112 for regulating each pixel 1313 of pixel groups 1311 the most successively according to the brightness value of progression and every grade of regulation.
When carrying out brightness regulation, if the amplitude of accommodation of each pixel 1313 is discrepant, the most by a certain percentage or
Algorithm is adjusted, and brightness value 5 is adjusted to 10, and 8 are adjusted to 16, and regulation multiple is 2 times.Now can be bright with display screen according to object brightness
Difference and progression between degree determine every grade of brightness flop value regulated.But, brightness flop value is that integrated display screen 130 is each
Individual pixel 1313 overall brightness changing value.The changing value of every grade of regulation of each pixel 1313 is calculated further according to brightness flop value.
The brightness of each pixel 1313 is regulated again by the mode of default regulative mode packet timesharing.So, the change of brightness can be made more
Relax, it is to avoid to the sensation that human eye is uncomfortable.
Referring to Figure 14, what deserves to be explained is, above-mentioned progression refers to when all pixels 1313 all complete Primary regulation (i.e.
One cycle) it is one-level, corresponding progression.The most each pixel groups 1311 includes two pixels 1313, A pixel and B pixel.?
In one cycle, first regulate the A pixel of all pixel groups 1311, then regulate the B pixel of all pixel groups 1311, after completing, week
Phase terminates, and completes the regulation of one-level in other words.
Calculate brightness flop value, the change of every grade of regulation of each pixel 1313 can be calculated according to brightness flop value
Value.Then according to the regulation order preset regulates each pixel 1313 brightness of each pixel groups 1311 one by one, such as A pixel > B picture
Element > A pixel.
But, the number of pixels in the pixel groups of embodiment of the present invention is not limited to 2, it is also possible to be 3 and 3 with
On.
When carrying out brightness regulation, if the amplitude of accommodation of each pixel 1313 is identical, regulation the most simultaneously is fixed
Value, as brightness value 5 is adjusted to 6,8 are adjusted to 9, all one minimum brightness unit 1 of regulation.Now the mode according to packet timesharing is adjusted
Joint, the most each pixel groups 1311 includes two pixel A and B, and timesharing regulates, and first the A pixel of all pixels 1313 grades is lightened
One unit, then the B pixel of all pixels 1313 grades is lightened a unit.When regulating, there is a half-pix 1313 to raise every time
1, and second half no change, the brightness flop value being equivalent to entirety is 0.5.
And if do not use the mode of packet timesharing, every time the brightness flop value of regulation is at least 1.Therefore, packet point is used
Time regulative mode the change of brightness can be made more to relax, it is to avoid to the sensation that human eye is uncomfortable.
In some uses the embodiment of packet time-sharing format, electronic installation 100 includes the point corresponding with display screen 130
Array of source (not shown)；The corresponding one or more point sources of each pixel 1313.It is to say, pass through the bright of point of adjustment light source
Degree, it is possible to regulate the display brightness of the pixel 1313 of its correspondence.In S2, in the way of being grouped timesharing, regulate each point source
Brightness is to regulate the brightness of each pixel 1313.
Such as, in some embodiments, display screen 130 can be OLED display screen 130.OLED(Organic
Light-Emitting Diode) there is self luminous characteristic, therefore OLED display screen 130 can realize pointolite array, passes through
Control the brightness of each point source to regulate pixel 1313 brightness.Additionally, OLED display screen 130 has, thickness is thin, it is good to do pinking,
The advantages such as viewing visual angle is wide, response is rapid, luminous efficiency is high, bent.
Regulate pixel 1313 brightness by controlling the brightness of the point source corresponding with pixel 1313, control more direct, ring
Should be fast.By the brightness of point of adjustment light source, can realize being grouped the brightness adjustment approach of timesharing, reach eye protection effect.
The electronic installation 100 of embodiment of the present invention can include the control device of display screen 130 and above-mentioned embodiment
