Please refer to Fig. 2, it has illustrated the functional block diagram of the release of an interleave image processor 10 with motion compensation of a preferred embodiment of the present invention.Release of an interleave image processor 10 is for converting the field of interlacing (interlaced scan) to the frame of P-SCAN (progressive scan), the even number line lacking in the odd field of soon staggered processing of meaning or even field or the pixel interpolation of odd-numbered line generate, and are reduced into a complete frame.Release of an interleave image processor 10 comprises time motion compensation module (time-domain motion compensation unit) 100, space motion compensation module (space-domain motion compensation unit) 200 and motion compensation mixing module (motion compensation blending unit) 300.For more clearly demonstrating the present invention's running, please separately with reference to Fig. 3, it has illustrated the flow chart of the release of an interleave image processing with motion compensation of a preferred embodiment of the present invention.First, in step 310, time motion compensation module 100 for according to when the previous field Fn-1 of front court Fn and after a Fn+1, produce time interpolator pixel P3di and corresponding time motion-vector quality index I3di in a Fn, comprise time mobile estimating unit 110, time pixel interpolation unit 120 and time motion-vector quality index generation unit 130.Then, in step 320 and 330, space motion compensation module 200 is for lastrow Ln-1 and a next line Ln+1 according to field Fn row Ln to be compensated, produce inter polated pixel P2di and corresponding sawtooth index (Jaggy Index) Ij between row Ln hollow, comprise mobile estimating unit, space 210, pixel interpolation unit, space 220 and sawtooth detecting unit 230.Finally, in step 340, motion compensation mixing module 300, for according to time interpolator pixel P3di, space inter polated pixel P2di, time motion-vector quality index I3di and sawtooth index Ij, produces motion compensation pixel PMCDi.
Please refer to Fig. 4, further illustrate the operation workflow of time motion compensation module 100.In step 312, the previous field Fn-1 of 110 pairs one of time mobile estimating unit until inter polated pixel Pxy and after a Fn+1 carry out block comparison calculation, to determine according to time motion-vector MV3D.Separately, with reference to Fig. 5 A, it is the schematic diagram of decision time motion-vector.In the Fn of front court, pixel Pxy treats inter polated pixel, and block 520,540 is a comparison blocks size, and region 510,530 is a comparison region.In the time that determines pixel Pxy, during motion-vector, in region 510,530, with the size of block 520,540, carry out block comparison.The mode that this motion-vector estimation is processed time can be looks for previous field Fn-1 and block the most similar in a rear Fn+1, and search area can be whole or part field.Consider under the situation of operand, preferred embodiment of the present invention adopts absolute value error summation (Sum of Absolute Difference; SAD) algorithm, when the absolute value error summation of certain two block is minimum, this two block is Best similarity block, and its corresponding vector is the time motion-vector of pixel Pxy, and algorithm is as follows:
SAD ( i , j ) = Σ k - 0 N - 1 Σ l - 0 N - 1 | C ( x + k , y + l ) - R ( x + i + k , y + j + l ) , - p ≤ i , j ≤ p
Motion-vector is (m, n), makes i=m, and SAD during j=n is minimum, wherein
(1) N represents the length of block and wide;
(2) C (x+k, y+l) represents in target image field, the point in target image block;
(3) R (x+i+k, y+j+l) representative is in reference to image fields, with reference to the point in image block;
(4) p represents search area.
This case invention preferred embodiment of take is example, for reducing complexity and cost-effective consideration, selects the one-dimensional area that block 520,540 is 1*5, and the region that region 510,530 is 5*10.The SAD that supposes the block 540 in block in comparative result previous field Fn-1 520 and a rear Fn+1 is minimum, and motion-vector MV3D is the time motion-vector MV3D of pixel Pxy.Large I that it should be noted that block 520,540 and region 510,530 is different in response to the demand of implementation, non-restrictive condition of the present invention.

I3di=|MV3D-MV1|+|MV3D-MV2|+|MV3D-MV3|
The formula that the time motion-vector quality index I3di of another embodiment of this case determines also can be as follows:
I3di=Max(|MV3D-MV1|,|MV3D-MV2|,|MV3D-MV3)|
As time motion-vector quality index I3di hour, represent this treat the time motion-vector MV3D of inter polated pixel Pxy with around and the motion-vector of pixel corresponding to previous field close, also mean mobile trend close, therefore the confidence level of time motion-vector MV3D and time interpolator pixel P3di is very high; Contrary, when the time, motion-vector quality index I3di was large, represent this treat the time motion-vector MV3D of inter polated pixel Pxy from around and the motion-vector of pixel corresponding to previous field different, also mean and there is no identical mobile trend, therefore the confidence level of time motion-vector MV3D and time interpolator pixel P3di is very low.
Next, further space motion compensation is processed, and please also refer to Fig. 6, it is for producing the flow chart of space compensation pixel.In step 322, between at least lastrow and next line for the treatment of inter polated pixel Pxy in 210 pairs of mobile estimating unit, space current figure field Fn, (this case invention preferred embodiment is between row Ly-3~Ly+3) carries out block comparison, produces a space move angle.Then, please refer to Fig. 8, Pxy treats inter polated pixel, and block 820 is a comparison blocks size, and region 810 is a comparison region.In this case invention preferred embodiment, for reducing complexity and cost-effective consideration, select the one-dimensional area that block 820 is 1*5, and the region that region 810 is 7*10 (between row Ly-3~Ly+3).And block comparison also adopts absolute value error summation (Sum of Absolute Difference; SAD) algorithm, according to lastrow Ln-1 and next line Ln+1, two blocks of the SAD minimum producing, determine the space move angle of this pixel Pxy.Large I that it should be noted that block 820 and region 810 is different in response to the demand of implementation, non-restrictive condition of the present invention.Then,, in step 324, pixel interpolation unit, space 220, according to the space move angle of this pixel Pxy, first finds two pixels corresponding in lastrow Ln-11 and next line Ln+1, then produces according to this space inter polated pixel P2di to pixel Pxy.The production method of this space inter polated pixel P2di, can select this two pixel one of them, the pixel value maybe this two pixels weighted average being produced.
Then, please refer to Fig. 7, it is for determining the flow chart of sawtooth index.In step 332, mobile estimating unit 210, space, in the process of block comparison, produces a high specific to difference Max SAD and a minimum comparison difference Min SAD.Then, sawtooth detecting unit 230 to difference Max SAD and this minimum comparison difference Min SAD, produces a sawtooth index Ij according to this maximum, for providing motion compensation mixing module 300 judgement spaces to move the confidence level of inter polated pixel P2di.The formula that the sawtooth index Ij of this case preferred embodiment determines is as follows:
Ij=Max?SAD–Min?SAD
As sawtooth index Ij hour, represent the lastrow Ln-11 that this treats inter polated pixel Pxy and next line Ln+1 is non-is in edge zone (edge), therefore the with a high credibility of inter polated pixel P2di moved in space; On the contrary, when sawtooth index Ij is large, represent that lastrow Ln-11 and next line Ln+1 that this treats inter polated pixel Pxy are in edge zone (edge), therefore the with a low credibility of inter polated pixel P2di moved in space.
Finally, in step 340, motion compensation mixing module 300, for according to time interpolator pixel P3di, space inter polated pixel P2di, time motion-vector quality index I3di and sawtooth index Ij, produces a motion compensation pixel PMCDi to this pixel Pxy to be compensated.Motion compensation mixing module 300 can be according to time motion-vector quality index I3di and sawtooth index Ij, be chosen to be time interpolator pixel P3di or space inter polated pixel P2di one of them as this motion compensation pixel PMCDi; Or can determine a weighted number α by time motion-vector quality index I3di and sawtooth index Ij, time interpolator pixel P3di and space inter polated pixel P2di are weighted to average computation, to produce this motion compensation pixel PMCDi.So the motion compensation pixel PMCDi of this case invention preferred embodiment determines to adopt the latter's mode, and formula is as follows:
PMCDi=α*P3di+(1-α)*P2di
α=f (I3di, Ij)=min max (a*I3di – b*Ij, 0,1) wherein
The explanation of the invention described above preferred embodiment, is motion compensation release of an interleave image processor and method, is considering the impact of picture moving, for generation of the pixel value of pixel to be compensated in.If but add the mechanism of static compensation, and in the situation of picture still, have better compensation effect, refer to following explanation.
Please refer to Fig. 9, it illustrates the functional block diagram of the release of an interleave image processor 90 with motion compensation of another preferred embodiment of the present invention.Similarly, release of an interleave image processor 90 is for converting the field of interlacing (interlaced scan) to the frame of P-SCAN (progressive scan), the odd-numbered line lacking in the odd field of soon staggered processing of meaning or even field or the pixel interpolation of even number line generate, and are reduced into a complete frame.Release of an interleave image processor 90 comprises motion compensation module 910, static compensation module 920, mobile detection module 930 and release of an interleave mixing module 940.For more clearly demonstrating the present invention's running, please separately with reference to Figure 10, it illustrates the release of an interleave image processing flow chart with motion compensation of another preferred embodiment of the present invention.First, in step 1010, motion compensation module 910, for generation of a motion compensation pixel PMCDi, comprises any consideration time or space and moves factor, the method for the motion compensation pixel that produces.The devices and methods therefor that this motion compensation pixel PMCDi can be disclosed by earlier figures 2 and Fig. 3 is produced, but is not limited to this mode.Then,, in step 1020, static compensation module 920 and mobile detection module 930 produce respectively a static compensation pixel PSCDi and and move index Im.Finally, in step 1030, release of an interleave mixing module 940, according to motion compensation pixel PMCDi, static compensation pixel PSCDi and mobile index Im, produces a release of an interleave pixel PDi.
In more detail, please refer to 1 Figure 11, it has illustrated and has produced the detail flowchart that a static compensation pixel PSCDi and moves index Im.In step 1022, static compensation module 920 select this wait mend pixel Pxy previous field Fn-1 or after the pixel of a Fn+1 same position, as this static compensation pixel PSCDi; Or the pixel average of calculating previous field Fn-1 and a rear Fn+1 same position, as this static compensation pixel PSCDi.In step 1024, mobile detection module 930, according to the related pixel of this pixel Pxy to be mended, moves index Im to produce this.Preferred embodiment of the present invention, for calculating the difference of the pixel of previous field Fn-1 and a rear Fn+1 same position, is moved index Im as this, and calculating formula is as follows:
Im=|Pn-1–Pn+1|
Another embodiment of the present invention is the mobile index being calculated as according to this pixel Pxy to be mended at least one related pixel around and in field, front and back, calculates this and moves index Im.Wherein in the present embodiment, related pixel is this pixel Pxy lastrow to be mended and next line par position surrounding pixel (Pxy-1, n, Px-1y-1, n, Px+1y-1, n, Pxy+1, n, Px-1y+1, n, Px+1y_1, n), and the surrounding pixel (Pxy of previous field and a rear same position, n-1, Px-1y, n-1, Px+1y, n-1, Pxy, n+1, Px-1y, n+1, Px+1y, n+1), calculating formula is as follows:
