Motion type decision apparatus and method thereof

摘要

A motion type decision apparatus and method thereof are provided. A first decision unit determines the presence of motion in a current block for compensation, by extracting first and second high frequency signals from first and second blocks of a previous and a current frame/fields corresponding to a zero motion vector of the current block to set a first threshold, and comparing a first motion estimation error value between the first and the second blocks with the first threshold. A second decision unit determines the presence of motion in the current block, by extracting third and fourth high frequency signals from third and fourth blocks, setting a second threshold, and comparing a second motion estimation error value with the second threshold. A motion type decision unit determines a motion type of the current block by comparing the motion determinations of the first and the second decision units.
