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.
