<p><P>PROBLEM TO BE SOLVED: To oppress effectively a distortion component changed in time without giving a severe deterioration of image quality to a picture. <P>SOLUTION: It has a data compression processing circuit which performs compression coding processing of the input video data. In an image processing system which possesses a coding instrument which records the compression video data from this data compression processing circuit on a magnetic tape, and a decoding apparatus which includes a data decompression processing circuit 22 for reconstructing the compression video data to the original reproducing video data Dv, performing transformation decoding processing of the compression video data dv currently recorded on the magnetic tape, it establishes and constitutes a distorted oppression processing means 41 to perform a band-limitation in time duration longitudinal accommodative to reproducing video data BDv after restoration, on the basis of a movement vector data and a vector detection information detected by motion compensation processing, and an edit information sh detected by a detection circuit in a recording decoding machine 31, in a post stage of the data decompression processing circuit 22. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
