ABSTRACT:
An evaluation value operation part computes evaluation values of a template block and a search window block in accordance with respective ones of a plurality of predictive modes in parallel with each other, and a candidate vector determination part decides candidate vectors indicating optimum vectors in accordance with the computed evaluation values and on the basis of priority levels from a priority generation part. In accordance with these candidate vectors, an optimum vector decision part decides the optimum vectors for the respective predictive modes. Thus provided is an image coding system which can reduce the amount of codes of motion vectors with excellent picture quality.
