The brightness ratio of each block between two independent display control regions.
For the brightness adjusting method convenient for being more clearly understood that the display screen of first embodiment of the invention, spy is lifted into tool below
Body example is described in detail.
Assuming that display resolution is 640*640, it is 128* that display control card, which for example receives cassette tape and carries area size,
128.It is that unit adjusting display screen is bright that the embodiment of the present invention, which will preferably receive cassette tape and carry multiple fritters that regional simulation is divided into,
Degree: for example, each receptions cassette tape load region (128*128) is modeled and is divided into multiple 8*8 fritters, then entire display screen viewing area
Domain can be divided into 80*80 8*8 fritter, and each 8*8 fritter is corresponding with a brightness adjustment, then treated, and image transition is equal
It is even, obvious bulk effect is not present.Below to simplify explanation, every reception card is arranged using M and is simulated as unit along line direction
It is divided into fritter.
(1), principle illustrates:
Here by taking the screen of court as an example, illustrate the realization step of the embodiment of the present invention；It is well known that the control of LED display
It is realized typically by multiple reception cards, it is each to receive card control/a part of display area with load LED display.
The present embodiment captures the illumination data that the reception cassette tape carries region by receiving the one or more light probes of card configuration for every
(namely intensity of illumination data) then receive the illumination data that card obtains to individual and average to obtain mean value illumination as the reception
The illumination in cassette tape load region；Since there may be errors for collected illumination data, it is therefore desirable to all mean values for receiving card
Illumination carries out low-pass filtering, to guarantee the flatness of mean value illumination；Then it is closed according to the illumination and brightness ratio appointed in advance
It is table Table (such as shown in Fig. 2, the 1st is classified as illumination, and the 2nd is classified as brightness ratio) and the identical columns M of brightness ratio, meter
Calculating the brightness ratio that every M is arranged, (wherein Table (i, 1) indicates the illumination of the i-th row in Fig. 2, and Table (i, 2) indicates corresponding i-th row
The brightness ratio of illumination)；Finally the brightness ratio calculated is applied on corresponding M column LED light point.Wherein, every reception card
The light probe quantity of configuration may be the same or different.
(2), brightness adjusting method process:
(a) it acquires every and receives the initial illumination data [IntensityValue that card is captured by light probe1,
IntensityValue2,...,IntensityValueN], individual is set herein receives card configured with N number of light probe；
(b) it calculates every and receives the initial illumination data mean value of card acquisition to obtain receiving the mean value illumination of card
IntensityAvg；
It (c) is the influence of the deviation of the collected initial illumination data of guarantee, to all reception cards of LED display configuration
Mean value illumination carry out low-pass filtering with obtain every receive card filtering after mean value illumination IntensityFinal, to ensure to count
According to flatness；Exclude the influence of abnormal illumination data；The main purpose of low-pass filtering is to carry out abnormal mean illumination herein
Amendment, because there may be the situations of light probe failure in practical applications, if having been acknowledged that light probe is normal in advance certainly,
It is contemplated that omitting the low-pass filtering step.
(d) it according to the illumination and brightness ratio relation table (such as shown in Fig. 2) being previously set, calculates every reception and is stuck in
Brightness ratio under corresponding illumination IntensityFinal, can calculate here according to bilinear interpolation:
Assuming that the illumination data to be solved for receiving card is IntensityFinal, it is located at illumination and brightness ratio relation table
Between the Nth row and N+1 row of (such as shown in Fig. 2), then the brightness ratio of the reception card calculates as follows:
1) the distance Dis1=of Nth row brightness value in the illumination data IntensityFinal distance relation table of card is received
IntensityFinal-Table(N,1)；
2) distance for receiving N+1 row brightness value in card illumination data IntensityFinal distance relation table is Dis2=
Table(N+1,1)-IntensityFinal；
3) coefficient of bilinear interpolation is respectively Coef1=Dis2/ (Dis1+Dis2), Coef2=Dis1/ (Dis1+
Dis2)；
4) brightness ratio being stuck under corresponding illumination IntensityFinal is received are as follows: BrightnessValue=Coef1
×Table(N,2)+Coef2×Table(N+1,2)。
Each, which is calculated, according to step (d) receives brightness ratio of the card realization at corresponding illumination IntensityFinal；
Herein it is understood that receiving card illumination data IntensityFinal energy just in illumination and brightness ratio relation table
Enough directly inquiries obtain, then without carrying out interpolation calculation.
(e) it according to the identical columns M of brightness ratio set, calculates and receives the bright of the realization for blocking upper every M column LED light point
Degree ratio:
1) assume that adjacent two receptions card is respectively according to step (d) illumination corresponding brightness ratio calculated
BrightnessValue1 and BrightnessValue2, adjacent two reception cassette tapes carry for example adjacent two receptions between region
Cassette tape carries between two edges being located remotely from each other in region, between adjacent two reception cassette tapes load regional center etc., and preferably
It is TotalNum with the LED light points carried between regional center, then two LED light points received between cassette tape load regional center can
It is arranged as the group number of unit using M as DivisionNum=ceil (TotalNum/M) using marking off, (ceil indicates the letter that rounds up
Number)；
2) the brightness ratio difference value per adjacent M column LED light point is Diff=(BrightnessValue2-
BrightnessValue1)/DivisionNum；
3) brightness ratio that each final M column LED light point is realized are as follows: BrightnessPerDivisionDivisionCount
=BrightnessValue1+ (DivisionCount-1) × Diff, wherein DivisionCount indicates which M is arranged, model
It encloses for [1, DivisionNum].
It calculates according to step (e) to every and receives the brightness ratio for blocking each M column LED light point.
(f) finally the brightness ratio calculated is acted on LED display, realizes required effect.
In addition, it is noted that in order to be applicable in the diversity of practical matter and to the diversity of brightness demand, here
Using illumination shown in Fig. 2 and brightness ratio relation table Table and the identical columns of brightness ratio as the revisable number of user
According to.
Furthermore, it is worth mentioning at this point that, present invention is not limited to using the identical side of every M column brightness ratio
Formula correspondingly can also can calculate each every M column LED light for receiving card according to step (e) using M × M as minimum unit
After the brightness ratio of point, then does calculate the bright of every M row LED light point similar to the step of step (b) and step (e) in a column direction
Degree ratio, so that the brightness ratio of every M × M minimum unit be calculated.Certainly, M × M minimum unit can also be replaced and be embarked on journey
LED light is counted different block of cells on column direction.
