1. A pixel data selection device for motion compensated interpolation, comprising: a first storage portion and a second storage portion respectively storing first pixel data and second pixel data, the first pixel data corresponding to a first motion vector of a first frame/field that is obtained by delaying an input frame/field, the second pixel data corresponding to a second motion vector of a second frame/field that is obtained by delaying the first frame/field one or more times; a first pixel data extract portion and a second pixel data extracting portion respectively extracting individual pixel data from the first and the second pixel data corresponding to a plurality of candidate motion vectors; and a first optimum pixel output portion and a second optimum pixel outputting portion outputting optimum pixel data for the motion compensated interpolation from the extracted individual pixel data.
