The above embodiment of the present invention provides a kind of method of the PDP of raising image quality; Be included in the problem that reduces 50HZ image large-area flicker when reducing dynamic false contour; This method is included in and selects two opposite sub-field code modes on the basis of PPC, every frame or whenever switch different coding at a distance from several frames.Two kinds of opposite coded systems of employing of two parts non-uniform light of the inside of the frame of the same field picture of 50HZ wherein.The present invention solves the scintillation that causes non-uniform light to produce by coding through adopting two kinds to be coded between every frame and to switch, and perhaps adopts multiple coded system between frame and frame, to switch use, solution non-uniform light property problem.
Fig. 7 is the sketch map of G1 and two parts of G2 in the two field picture after encoding according to the employing first kind sub-field code mode of the embodiment of the invention; Fig. 8 is the sketch map of G1 and two parts of G2 in the two field picture after encoding according to second type of sub-field code mode of employing of the embodiment of the invention.
For achieving the above object; The present invention be the technical scheme taked concrete be; Like Fig. 7 and shown in Figure 8; When the 50HZ image shows, generally adopt PPC ground mode and be divided into two part G1 and G2 to the demonstration of a two field picture, in order to make the flicker of human eye perceives less than image, preferably G1 and the luminous sum total of G2 equate or differ less.But in order to reduce dynamic false contour, the sub-field code of preferred some produces remaining sub-field code through the mode of shaking then and shows.Just occur two adjacent coding weights easily at the sub-field code of selecting and differ bigger situation, G1 and G2 promptly can occur and differ bigger situation, jump to than show on the big weight like coding on the next encoding ratio.So take two seed field coded systems in order to solve luminance nonuniformity weighing apparatus ground problem; First kind of coding wherein adopts coded system as shown in Figure 7; Fig. 7 is the luminous sketch map of coded system 1; According to first kind of luminous situation of encoding scheme, the last period, the G1 part was luminous bigger in a frame for this schematic view illustrating, and G2 is luminous less.Second kind of coded system that adopts first kind of front and back section to put upside down is as shown in Figure 8; Fig. 8 is the luminous sketch map of coded system 2; According to second kind of luminous situation of encoding scheme, the last period, the G1 part was luminous less in a frame in this Fig. 8 explanation, and back one section G2 part is luminous bigger.Encode according to this dual mode, to two sub-field mapping tables should be arranged.In shake; 12 select encoding according to corresponding situation with coding; Make G1 and G2 in several two field pictures, keep luminous sum total to equate, human eye just can not felt flicker like this, luminously differs bigger problem for having remedied because of what reduce that the dynamic false contour optimized encoding causes.Wherein, a son mapping table is exactly the relation that coding uses: 1,2,3,5,8,12,18,20, and 32,48,56,60 these weights are exactly the corresponding weights of 12 sub-field, both a son mapping table.
For example, two kinds of following original 12 sub-field that adopt of coded system are encoded in order, can be 1,2,3,5,8,12; 18,20,32,48,56,60 this codings increase in order, are 1,3 in proper order when adopting like Fig. 7 and coded system G1 shown in Figure 8; 8,18,32,56, G2 is 2,5,12; 20,48,60, above-mentioned this form forms two maximum brightness values in a two field picture, and it is two that original brightness maximum of points is tied, and brightness is more even on time shaft, has reduced flickering.Coded system 1 is used G1, and the sequential encoding mode 2 of G2 is used G2, the order of G1.Be characterized in adopting the coding of different weights to make up, combination is divided into two groups: G1 and G2, these two kinds of coded systems can make up use.
In the foregoing description, in order to reduce the generation of dynamic false contour, preferred several sub-field codes as shown in table 1; For example coding 21 between the coding 22 because the introducing of the big son of new weight, having caused has a bigger phase difference between them, consequent problem is the luminous no longer equilibrium of G1 and G2 part; When producing their middle gray scale by 21 and 22 shakes, because the G1 part is luminous bigger, the G2 part is luminous less like this; Between frame and frame because during irregular shake, can be through being everlasting coding 21 and encode and select between 22, this sampled images have neglect secretly bright suddenly; Can produce the sensation of flicker,, need when second frame shows, make the G2 part luminous bigger in order to remedy this difference; And luminous less alternately the occurring of G1 part encoded the second seed field coded system as shown in table 2 so need partly change encode G1 and G2; Two sub-field coding schedules are so just arranged; According to switching between these two every frames of coding schedule, from the time, guarantee G1 and the luminous isotropism of G2 can not produce the sensation of flicker.
In this example, can also add multiple coding, make the position lack of uniformity of giving out light of coding more remedied the large-area flicker problem that so just can reduce to cause thus.
From above description; Can find out; The present invention has realized following technique effect: solved to relate in the correlation technique when showing 50HZ about the mode that combines in PPC and dither image Processing Algorithm and brought the problem of certain gray scale large-area flicker, and then reached the flicker degree that reduces display, improve user experience effect.
Need to prove; Can in computer system, carry out in the step shown in the flow chart of accompanying drawing such as a set of computer-executable instructions; And; Though logical order has been shown in flow chart, in some cases, can have carried out step shown or that describe with the order that is different from here.
Obviously, it is apparent to those skilled in the art that above-mentioned each module of the present invention or each step can realize with the general calculation device; They can concentrate on the single calculation element; Perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element; Thereby; Can they be stored in the storage device and carry out, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize by calculation element.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
