Description
Technical field
The present invention provides a kind of image data displaying method, refers to a kind of pixel drive of motion blur width and method of image data displaying of dwindling especially.
Background technology
Along with lcd technology is day by day ripe, using display panels has become trend as LCD TV.Yet LCD TV is subject to the physical characteristic of liquid crystal, and more traditional kinescope TV is slow on the reaction speed of animate, and causes producing motion blur (motion blur) at the image edge of mobile object (moving subject).In order to reduce the motion blur degree on the animation, prior art has proposed a kind of improvement method of frequency multiplication.
See also Fig. 1.Figure 1 shows that adjacent two pixels 101 and 102, it receives respectively and demonstration luma data A and B in image time (frame time) Tf.See also Fig. 2.The black plug picture that is proposed in the prior art is to improve the method for motion blur, be when pixel 101 and 102 receives luma data A and B, cooperate the image frequency doubling technology, cover a normal sprite (normally blacksub-frame) of deceiving that shows, promptly a GTG value is 0 sprite; Make pixel 101 and 102 as shown in Figure 2, only show respectively in preceding half image time that luma data is the sprite of A and B, and in later half image time, be black picture.Thus, (eye-tracking model) can get according to human eye trace model, uses this existing black plug picture method blurred width (blur width) is approximately reduced by half.Yet, because this existing black plug picture method makes that pixel is only correct in the time of half and shows luma data, and to be luma data be second half time 0 normally show black picture, therefore will make that picture brightness reduces by half, influence image effect.
For the pixel brightness that method caused that the improves above-mentioned black plug picture problem that reduces by half, existing have one not influencing the method that shortens blurred width under the picture brightness in addition.See also Fig. 3.When pixel 101 and 102 was received luma data A and B, this existing method allowed pixel 101 show sprite A ' and C in regular turn, and allows pixel 102 show sprite B ' and D in regular turn according to predetermined principle.Pixel 101 shows the mean flow rate of sprite A ' and C in image time Tf, all showing that the brightness effects of luma data A is identical in the image time Tf with direct among Fig. 1; And pixel 102 shows the mean flow rate of sprite B ' and D in image time Tf, is all showing that the brightness effects of luma data B is identical in the image time Tf with direct among Fig. 1.Please consult Fig. 4 again.One example of existing method employed predetermined principle when producing sprite that the table of comparisons 40 shown in Figure 4 is shown in Figure 3 for this reason.Therefore, according to Fig. 3 and Fig. 4, this existing method can show that in regular turn luma data is 250 and 0 two sprites when a pixel receives an original luma data 150; And when a pixel receives an original luma data 151, show that in regular turn luma data is 255 and 0 two sprites.In the table of comparisons shown in Figure 4 40, be not more than 151 original GTG value and can be covered a black picture, promptly produce a luma data and be 0 the 2nd sprite and the 1st sprite of collocation mutually, so that the comprehensive brightness effects of two sprites equals the brightness of original GTG value; Then can be covered a luma data in the original GTG value more than 152 is 255 the 1st sprite and the 2nd sprite of a correspondence, makes the comprehensive brightness effects of two sprites equal the brightness of original GTG value equally.In general image data, the GTG value of adjacent pixel is often close; Therefore if the original GTG value of two pixels 101 among Fig. 3 and 102 all less than 151, then the GTG value C of sprite will equate with D and be all 0; If the original GTG value of pixel 101 and 102 is all greater than 152, then the GTG value A ' of sprite will equate with B ' and be all 255.These two kinds of situations all can make the image fog width approximately reduce by half, and the not brightness of image image again.Fig. 5 is the coordinate figure corresponding to the table of comparisons 40 of Fig. 4; Wherein original GTG value is 255 greater than the GTG value of its first sprite of g51 person, and original GTG value is 0 less than the GTG value of its second sprite of g51 person.Other note that first sprite among Fig. 4 and the DISPLAY ORDER of second sprite can put upside down, so is referred to as with high brightness sprite and low-light level sprite among Fig. 5; But the DISPLAY ORDER of whole image must unanimity (be that all first exhibit high brilliance sprite of each picture shows the low-light level sprite again, or each picture showing low-light level sprite exhibit high brilliance sprite more all earlier).G51 value among Fig. 5 can be any design load, and for instance, when being applied to represent system as one or eight bit GTGs as Fig. 4, g51 can be 151.
More than be two kinds of methods that reduce the image fog width commonly used in the prior art.Yet these two kinds of methods cover the normal sprite that shows black (normally black) all in a large number, and the reaction speed of display panels forms a restriction then.When a liquid crystal cells need in normal show the black mole picture after and then show the higher sprite of GTG value the time, have little time reaction possibly, and make be connected on normal apparent black mole picture after the higher sprite brightness of this GTG value be lower than given GTG value.Again or when a liquid crystal cells needs and then to show a normal apparent black mole picture behind the higher sprite of a GTG value, promptly have little time to reduce to predetermined GTG value brightness easily, and make that being connected on normal behind the higher sprite of this GTG value shows the too high but not standard of the brightness of black mole picture and normally show and deceive picture.
See also Fig. 6.Figure 6 shows that a liquid crystal cells that adopts existing artistic illustration face method as shown in Figure 4 in one section continuous time t60 to t69, according to the raw frames GTG value that it received, produces corresponding sprite GTG value, again the corresponding diagram of the brightness that shows in regular turn.As shown in Figure 6, in time t60 to t64, the GTG value of liquid crystal cells received two raw frames f61 and f62 is 100, and should produce the GTG value in regular turn according to the rule of correspondence among Fig. 4 is 150,0,150 and 0 sprite.And in time t65 to t69, the GTG value of liquid crystal cells received two raw frames fs61 and fs62 is all 151, according to the table of comparisons among Fig. 4, should show in regular turn that the GTG value is 255,0,255 and 0 sprite.Yet, be subject to the reaction speed of liquid crystal cells, so liquid crystal cells is different and a difference DELTA y1 arranged in the shown brightness (L1) of the second sub-GTG of picture f61 and f62 at the shown brightness (L2) of picture fs61 and the second sub-GTG of fs62 and liquid crystal cells.
See also Fig. 7 again.Figure 7 shows that a liquid crystal cells that adopts existing artistic illustration face method in one section continuous time t70 to t79, according to the raw frames GTG value that it received, produces corresponding sprite GTG value, again the corresponding diagram of the brightness that shows in regular turn.As shown in Figure 7, to t74, the GTG value of liquid crystal cells received two raw frames f71 and f72 is 151 at time t 70, and should produce the GTG value in regular turn according to the rule of correspondence among Fig. 4 is 255,0,255 and 0 sprite.And in time t75 to t79, the GTG value of liquid crystal cells received two raw frames fs71 and fs72 is all 200, according to the table of comparisons among Fig. 4, should show in regular turn that the GTG value is 255,100,255 and 100 sprite.Similarly, be subject to the reaction speed of liquid crystal cells, so liquid crystal cells is different and a difference DELTA y2 arranged in the shown brightness (L5) of the first sub-GTG of picture fs71 and fs72 at the shown brightness (L4) of picture f71 and the first sub-GTG of f72 and liquid crystal cells.
Can find out that by the example that Fig. 6 and Fig. 7 lifted the reaction speed of liquid crystal cells can cause liquid crystal cells can't reach best animation quality when carrying out the GTG conversion; And liquid crystal cells in the shown brightness of picture fs61 and the second sub-GTG of fs62 with different in the shown brightness of the second sub-GTG of picture f61 and f62, and liquid crystal cells in the shown brightness of picture f71 and the first sub-GTG of f72 with different in the shown brightness of the first sub-GTG of picture fs71 and fs72, this also makes the distortion of liquid crystal cells show image, thereby do not reach desired motion blur width and the target of keeping correct brightness of reducing, reduced the usefulness of LCD.
