ABSTRACT:
An apparatus for and a method of transforming a scanning format can adaptively select a scanning format transformation method. A motion estimating unit estimates a final motion vector among the motion vectors determined by a full search and predicted motion estimation and determines a first motion estimation type of the final motion vector. A motion analyzing unit and a motion estimation type analyzing unit respectively determine an existence of a global motion and a third motion estimation type from the final motion vector. A motion compensating unit and a temporal-spatial interpolating unit generate a first pixel and a second pixel, respectively. A format transforming unit transforms the scanning format by adaptively selecting one of the first and second pixels on a basis of at least one of the third motion estimation type and the information on the existence of the global motion. As a result, the scanning format transformation method can be adaptively selected from a motion compensation method and a temporal-spatial interpolation method according to the motion type.
