Embodiment
Below with reference to accompanying drawing, describe the specific embodiment of the present invention in detail.
Fig. 1 is converted to the input gray grade image circuit diagram of YcrCb according to the embodiment of the present invention by RGB;
Carry out at first will carrying out the conversion to YcrCb by RGB to it in processing procedure at the input gray grade image.
As shown in Figure 1, in embodiments of the present invention, the input gray grade image calculates the APL value after turning YcrCb through RGB, and the APL value that calculates outputs to keeps pulse control unit, dynamically adjusts the umber of pulse of keeping of image by the APL value; And the formal output of encoding with 10 fields, seat after the RGB image of input shines upon through video enhancing, subfield.Can improve the stability of PDP power by above-mentioned scheme, realize that the gray level quality of image promotes.
The below describes the concrete grammar according to the lifting image grey scale quality of the embodiment of the present invention in detail.
At first, the APL account form of the embodiment of the present invention is as follows:
The contrast of PDP and brightness improve the main mode of keeping umber of pulse that increases that adopts.But it is more to keep umber of pulse, and the power consumption of whole screen will increase.According to the visual signature of human eye, the people is when watching the bright picture of view picture, and the contrast of picture is little on the picture impact, therefore can adopt the little umber of pulse of keeping to realize bright picture low-power consumption effect; The people needs to promote the stereovision between each GTG when watching the dark picture of view picture, so picture contrast is very large on the image quality impact.
Reduce simultaneously the power consumption of bright image in order to promote dark picture contrast, need to use the dynamic contrast solution, more common method is to adopt dynamically to keep pulse and control to realize this process.Namely adopt the more contrast enhancing that umber of pulse realizes picture of keeping according to statistics in dark picture, adopt the less power-dissipation-reduced that umber of pulse realizes picture of keeping in bright picture.Whole implementation method is little to the image-watching quality influence.This control method is called as APL (Average Power Level-average power level) control method.The APL Data-Statistics formula that shows image is:
Wherein x is image display position horizontal ordinate, and y is image display position ordinate, and I (x, y) is the brightness of this position epigraph, and C is the columns of whole picture, and L is the line number of whole picture;
Dynamically adjust the umber of pulse of keeping of image by the APL value that calculates, realizing the control of contrast and brightness, and realize that thus power controls.The power of realizing by APL is controlled and mainly finished the work is to carry out white from the 256-1000 gray level when showing, although gray level changes to 1000 from 221, in the time of whole complete white, the brightness amplitude of variation increases progressively and is not more than 60cd/m
2And PDP module power consumption is closely related with display brightness, and the power consumption of module remains unchanged substantially when the brightness variation is little, can well control by this method PDP power supply module, makes output power change relatively stable.
Simultaneously, theoretical according to the physiological vision of Weber human eye, even in the same luminance difference of the part of dark image, larger sensation is arranged also, discover less than same luminance difference in the bright image more than certain brightness.For example, brightness 1cd/m
2And 2cd/m
2Although be 1cd/m
2Difference, but the people thinks that luminance difference is very large, 100cd/m when seeing
2And 101cd/m
2Although two luminance differences are also 1cd/m
2, but human eye is not distinguished.Therefore, the more important thing is than the light characteristic that linearity increases, trickleer minute GTG in dark brightness strengthens luminance difference on bright picture, could distinguish GTG like this.
Test finds that human eye is to greater than 110cd/m
2The brightness of picture changes insensitive and to less than 110cd/m
2Picture change very responsive, therefore be that 400 places arrange node that APL changes and can make when showing image in low gray level change of power consumption violent in the entire image gray level, realize that details in a play not acted out on stage, but told through dialogues picture stereovision is abundanter, dynamic contrast is enhanced, and this moment because brightness less than 100cd/m
2The characteristics that are directly proportional according to PDP brightness and power consumption, the module power consumption also is far smaller than the required power consumption of normal demonstration brightness of image, therefore gray level was less than 400 o'clock, APL controls inoperative, keep umber of pulse with maximum and realize that image shows, this APL arranges and can not exert an influence to the components and parts of PDP module and power source life, the stereovision of image in the time of can pulling open low gray level simultaneously.Adjust APL in gray level greater than 800 o'clock needs as a same reason and make APL change slowly, keep pulse minimum, guarantee that Overall Power Consumption changes inviolent.
The APL control method can well solve the unbalanced impact that stability and the reliability of device and power supply are produced of change of power consumption in the demonstration of PDP dynamic image, simultaneously for the contrast of improving picture and the brightness dynamically again of dark picture, the improving picture quality, so the use of APL has very large benefit to power consumption and image quality raising.
But because the use of APL needs dynamically to keep the pulse adjustment according to the frame statistics, if in use to keeping pulse along with image change is processed the bad scintillation that will cause whole picture.Therefore, the APL algorithm need to adjust according to each grayscale image, and there are some unique algorithms in each company for the adjustment of this image.
By repeatedly practice, the present invention has drawn following APL curve, and as shown in formula (2), the image transition of utilizing this curve to realize is smoother and can not produce flickering.
Snum＝K
1×Gray
3+K
2×Gray
2+K
3×Gray+C
1 Gray≥400；
Snum＝C
2 Gray<400；(2)
Snum: keep umber of pulse Gray: whole figure input gray grade
Wherein, Gray is the entire image gray level ,-10＜K
1＜10 ,-10＜K
2＜10;-10＜K
3＜10,0＜C
1＜900; 0＜C
2＜1200.
Keep umber of pulse and whole figure input gray grade relation as shown in Figure 2 by what this formula calculated, this formula need to be done adjustment on coefficient to different screens certainly, can realize consistent display quality by coefficient adjustment.It may be noted that the coefficient in above-mentioned formula (2) is not limited to value listed in this formula, above-mentioned value is only one group of preferred value.
Fig. 3 is after adjusting through above-mentioned formula, the brightness of actual measurement and input gray level Relations Among.The actual output that can see the image of input brightness by real data is smoother, but also needs to do finer adjustment on indivedual gray levels.Because calculating parameter has the part that needs carry or round, the processing of this external low gray level need to be considered details in a play not acted out on stage, but told through dialogues brightness is reduced, so this form needs manually to adjust.Steady by realizing after the practical application adjustment in the transition between each GTG under same APL, the stereovision transition is balanced.As shown in table 1 through obtaining keeping form after above algorithm.
As can see from Figure 3, the actual output of image of input brightness is smoother, but gray-scale inversion has appearred in other gray level place, and this can have influence on the image output quality.
Solve that under same APL, the reasonable antidote of gray-scale inversion is PDP brightness calculation method, the method is mainly by the various luminescence phenomenons that produce in resetting in the PDP procedure for displaying, addressing, maintenance process are calculated, count each gray level actual displayed brightness and adjust the mapping relations of each subfield, by the luminosity after adjusting add up to keep umber of pulse by subfield distribute, the GTG adjustment, to realize the linear change of GTG in each concrete APL situation.This kind adjusted the main subfield mapping mode that relies on and realized.
In the present invention to the calculating of the actual luminescence efficiency of GTG as shown in Equation 3:
L
u(Codeword)＝L
pri+L
add+L
sus×N
um(S
us) (3)
L wherein
priBe the brightness that resets; L
addBe addressing brightness; L
susFor keeping brightness; N
umFor keeping number.
Carry out front and back gray level output brightness relatively after utilizing formula (3) to calculate the brightness value of gray level, do not increase progressively marquis when concerning when output brightness does not satisfy input gray grade brightness, think that this sub-field code exists the gray-scale inversion problem to adjust.Gray-scale inversion problem through whole screen after adjusting will be eliminated, and picture quality can improve greatly.
For example: each reset discharge will produce 0.2cd/m2 brightness in the drive waveforms of PDP, and each sustain discharge will produce 0.6cd/m2 brightness, and each address discharge will produce 0.6cd/m2 brightness.and the distribution of keeping pulse in normal demonstration 60%APL will be undertaken by the distribution mode of 1-2-3-6-11-19-29-40-54-90, the sub-field code of gray level 6 can write 0001000000 or 1110000000 like this, the corresponding luminosity that their produce is respectively 4.4cd/m2 and 5cd/m2 and the sub-field code form of gray level 5 can be 0110000000, the brightness that this encoding scheme produces is 4.4cd/m2, if gray level 6 adopts the first coded systems gray level 5 and 6 will occur can't to distinguish even in some cases like this, gray level 5 phenomenon brighter than gray level 6 caused gray-scale inversion.Therefore gray level 6 just need to be chosen 1110000000 coding form and prevent gray-scale inversion in sub-field code.The sub-field code adjustment of by the PDP brightness-formula, each gray level of still image being carried out step by step so just can be adjusted the luminous linearity of reality.
In Fig. 4, left figure is the actual output gray scale image that has the gray-scale inversion problem, and right figure is the actual output image after the elimination of gray-scale inversion problem, can find out that from image this technology can in the situation that the certain adjustment by sub-field code of APL improves the mutual relationship between gray level, realize normal gray level display.After adjusting, actual sub-field code form of the present invention is as shown in table 2.Under this scheme, the gray-scale inversion phenomenon of image will obviously be eliminated, and the pulse code scheme of keeping shown in cooperation table 1 can well realize that the GTG quality of image promotes.
