Abstract
A method includes storing a current field of a digital video signal. The method further includes storing a preceding field that immediately precedes the current field in the digital video signal, and storing a succeeding field that immediately succeeds the current field in the digital video signal. The method also includes examining the preceding and succeeding fields for motion at a locus of a current pixel to be interpolated. In addition, if any motion at the locus is less than a threshold, the preceding and succeeding fields are examined for motion at a respective locus of at least one pixel that is adjacent to the current pixel to be interpolated.
