Pixel data selection device for motion compensated interpolation and method thereof

摘要

A pixel data selection device for motion compensated interpolation and a method thereof selects pixel data in adjacent frame/fields. First and second storage portions respectively store first pixel data corresponding to a motion vector of a first frame/field that is obtained by delaying an input frame/field and second pixel data corresponding to the motion vector of a second frame/field that is obtained by delaying the first frame/field one or more times. First and second pixel data extracting portions extract individual pixel data from the first and the second pixel data corresponding to a candidate motion vector. First and second optimum pixel outputting portions output optimum pixel data for motion compensation from the extracted individual pixel data. By selecting the optimum pixel data from the adjacent frame/field of an interpolated frame/field having a current block and candidate blocks corresponding to a plurality of motion trajectories, occurrence of blocking artifacts due to inaccurate estimate of motion vectors can be reduced.
