<p>In a video coder an adaptive decision method for a motion vector search range is used which includes determination of motion vector values of blocks adjacent a block where a motion vector is to be decided, and then determination of a motion vector search range of the specific block is performed on the basis of the determined motion vector values of the adjacent blocks. The method preferably includes the steps of deciding a maximum range value of a local motion vector in horizontal and vertical direction of the block where a motion vector is to be decided and then deciding a minimum range value based on the maximum value and a search range value defined by a user.</p> |
