1. A pattern analysis-based motion vector compensation apparatus, comprising:

  • a motion estimation part for comparing a current block of a current frame or field with a certain search area established in a previous frame or field, calculating plural motion estimation error values, and estimating a temporary motion vector of the current block based on the plural motion estimation error values;

    a pattern decision part for analyzing the calculated motion estimation error values, and deciding whether the current block is a pattern image;

    a motion compensation part for producing a compensation motion vector of the current block by use of the plural motion estimation error values if the current block is decided as the pattern image; and

    a motion vector selection part for selecting as a final motion vector either the temporary motion vector estimated by the motion estimation part or the compensation motion vector compensated for by the motion compensation part based on a result of the pattern decision part.
