Abstract
For digital signals provided with motion vectors of a plurality of regions, a conversion coefficient for a respective one of the motion vectors is determined in accordance with the respective motion vector and a shape of a corresponding one of the regions on which the respective motion vector represents a motion, linear conversions of the digital signals are performed by using the respective coefficients of the motion vectors, and an accumulation is made of results of the conversions for the respective motion vector by the linear conversion step so that the linear conversions are overlapped with each other.
