Description
Technical field
The present invention relates to the image processing technique field, particularly a kind of system frequently that increases that increases image display frequency.
Background technology
Frame rate increases conversion (FRC, Frame Rate up-Conversion) is an emerging technical field, main purpose is the frame frequency (Frame rate) that increases video, to adapt to modern demand as Hi-Vision, for example the frequency of Hi-Vision picture requirement may be 60Hz or higher.Become the video of high-frequency picture by interpolated frame in original source video sequence, for example increase to per second 60 frames from per second 30 frames.
In the frame interpolation method, suppose and (to be called F at the n frame
n) (be called F with the n+1 frame
N+1) between insert a frame and (be called F
In).A kind of fairly simple mode is frame replay method (Frame repetition), and as shown in Figure 1, its practice is with frame F
nTwice of repeat playing is to replace frame F
InThough this interpolation method simply is easy to do, effect is bad, is easy to generate the phenomenon that image pauses.
At above-mentioned shortcoming, another kind of mode is to use the frame method of average (Frame Averaging), and as shown in Figure 2, its way is with frame F
nWith frame F
N+1Corresponding pixel is done on average, inserts frame F then
InIn the corresponding pixel, but its mathematical expression simple table is shown: Pixel (x, y, F
In)=[Pixel (x, y, F
n)+Pixel (x, y, F
N+1)]/2.Yet this method is because with frame F
nWith frame F
N+1Corresponding pixel is done on average frame F
InOn moving object be easy to generate blooming.
It is motion compensation formula frame interpolation method that another kind of frame rate increases conversion (FRC) technology.The notion of motion compensation formula frame interpolation method be frame and interframe the utmost point apart in the short time, it is to do linear moving in rectilinear direction that the motion track of all objects can be considered as, as shown in Figure 3, by using mobile estimating method (motion estimation) to calculate frame F earlier
nWith frame F
N+1Motion-vector (motion vector), again according to motion-vector to frame F
InRebuild.Carrying out frame F

N+1Be stored in the one frame buffer.Fig. 4 is the structural representation of frame buffer in the prior art, and Fig. 5 is the use synoptic diagram of frame buffer in the prior art, as shown in Figure 4, for increasing system handles efficient, uses 3 frame buffers, as frame F
nWith frame F
N+1Read with reconstruction frames F by frame buffer 0,1 respectively
InThe time, with frame F
N+2Write in the frame buffer 2.Please refer to Fig. 5, when time Ta, begin frame F
N+2Write in the frame buffer 2, read frame F by frame buffer 0

N+3, read frame F by frame buffer 1
N+1And display frame F
N+1The use principle of work of subsequent frame impact damper is all identical, repeats no more.
By Fig. 4 and Fig. 5 as can be known, this motion compensation formula frame interpolation method need be used three frame buffers, is carrying out reconstruction frames F simultaneously
InThe time, need read frame F
nWith frame F
N+1, not only increased system cost, also reduced system effectiveness.Hence one can see that, and the existing frequency system that increases that increases image display frequency still has many defectives.
