Patent ID: 6990148

Claim:
An apparatus for transforming a scanning format, comprising: a motion estimating unit estimating a final motion vector of a block to be interpolated by selecting one of a first motion vector determined by a full search and a second motion vector predicted by a candidate motion vector group, and determining a first motion estimation type of the final motion vector; a motion analyzing unit determining an existence of a global motion by analyzing the final motion vector, and providing information on the existence of the global motion; a motion estimation type analyzing unit determining a second motion estimation type of neighboring blocks disposed adjacent to the block to be interpolated, and determining a third motion estimation type according to the first motion estimation type, the second motion estimation type, and the information on the existence of the global motion; a motion compensating unit generating a first pixel for a frame and/or field to be interpolated from a reference frame and/or field by using the final motion vector; a temporal-spatial interpolating unit generating a second pixel for the frame and/or field to be interpolated from a current frame and/or field, the reference frame and/or field, and pixels obtained by the full search; and a format transforming unit transforming the scanning format by adaptively selecting one of the first and second pixels on a basis of one of the third motion estimation type and the information on the existence of the global motion.
