Tv system conversion apparatus

Caused by the television standards conversion tampering such as degradation of image quality, it can be stabilized by selecting the original image signals, or illustration image selection approaches to reduce the signal output from the motion compensation. The latter is the most suitable motion vector is compensated, and the minimum inter-image signal between the motion vector corresponding to the original image signal and the motion vectors of each image area respectively detected motion compensation difference . This reduced degradation effect can be detected by the motion vector is weighted, so that by filtering and motion compensation section contour image more smoothing method is enhanced.
