Abstract
PURPOSE:To realize the coding transmission with high efficiency by preparing plural moving vector corresponding to an input pattern block, comparing the pattern subject to moving compensation and the input pattern depending on the moving vector of each moving vector pattern, selecting the moving vector pattern whose distortion is minimized and sending the index. CONSTITUTION:Plural moving vector patterns obtained in advance comprising moving vectors corresponding to a prescribed number of input blocks are stored in a code block 1 and a matching discrimination circuit 2 moves the pattern stored in the frame memory 12 by using the moving vector pattern for each of prescribed number of pattern blocks. The value of the obtained pattern number of the patterns is compared with the input pattern and the moving vector pattern with least error, that is, least distortion is selected out and its index is sent to an entropy coder 10. The entropy coder 10 applies variable length coding to the index and sends the result to the transmission line and then to the receiver side. Thus, the quantity of information is sent while being compressed.
