MOTION VECTOR PROCESSOR

摘要

PURPOSE: To provide vector field post processing capable of preventing generation of an unchecked motion vector component even when a smooth vector field is generated by a post filter having linearity. CONSTITUTION: In the interpolation of movement compendation of a TV picture, a picture is divided into plural blocks and the motion vector of each block is determined. The block division has a defect that the boundary of blocks is observed a dirty window effect). In this invention, continuous vector fields are generated from a block vector field by the use of a center value filter and a motion vector based on the motion vector of an original block H adjacent to a sidewall block belonging to each of plural sub-blocks H1 to H4 is calculated from these seb-blocks H1 to H4.
