Abstract
The invention relates to a method and an apparatus for de-interlacing video data by utilizing motion compensation. The method includes performing an operation of motion estimation on a first pixel of the first field and a second target field to generate a first motion vector, wherein the second target field corresponds to the second field; generating a first reference pixel corresponding to the first pixel according to the first motion vector and the second field; and generating a target pixel of a target frame according to the first pixel and the first reference pixel.
