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 extracting portion and a second pixel data extracting portion respectively extracting individual pixel data from the stored first and the second pixel data corresponding to a plurality of candidate motion vectors, the stored first and second pixel data being stored in the respective first and second storage portions; a first optimum pixel output portion and a second optimum pixel output portion, each optimum pixel output portion outputting directly to a motion compensation interpolation portion optimum pixel data for the motion compensated interpolation from the extracted individual pixel data; a first delay portion outputting the first frame/field by delaying the input frame/field; and a second delay portion outputting a second frame/field by delaying the first frame/field, wherein the first and second pixel data extracting portions output extracted individual pixel data from the stored first and second pixel data to the first and second optimum pixel output portions, respectively, and the first and second optimum pixel output portions determine optimum pixel data based on the inputted individual pixel data inputted from the first and second pixel data extracting portions, respectively, and the motion compensation interpolation portion receives outputs directly from the first and second storage portions and the first and second optimum pixel output portions and generates motion compensation pixel data based on the outputs from the first storage portion, the second storage portion, the first optimum pixel output portion and the second optimum pixel output portion through a motion compensation process selected from a plurality of motion compensation processes according to a motion vector type.
