Abstract: PURPOSE: Fractional-pel motion estimation using estimated distortion values is provided to estimate half-pel (or other fraction-pel) motion reducing the computation load of the conventional algorithm without calculating distortion values as to each of eight half-pel locations around an optimum integer-pel location. CONSTITUTION: After performing integer-pel motion estimation to select the best integer-pel location, half-pel(or other fraction-pel) motion estimation is performed by estimating the distortion values for all of the surrounding half-pel locations by linearly interpolating using the distortion value for the best integer-pel location and the distortion values available from the integer-pel motion estimation analysis corresponding to the surrounding integer locations. And then, a partial set of this half-pel location is selected as a candidate half-pel location on the basis of lowest estimated distortion value, and a true distortion value is calculated as to these candidate locations. And, an optimum half-pel location is selected on the basis of the distortion values of the candidate half-pel location and the optimum integer-pel location. Then, this optimum half-pel location can be used in performing the difference step between integer frames whose motion of video coding scheme is compensated.
