ABSTRACT:
A method for determining a value for a missing target pixel in an interlaced video field during a de-interlacing process includes providing at least one lookup table that correlates motion data to at least one of a plurality of de-interlacing methods, generating motion data related to the missing target pixel, utilizing the related motion data to perform a lookup on the at least one lookup table, and selecting the at least one de-interlacing method correlated to the motion data to generate the value for the missing target pixel. A de-interlacing system includes a motion detection unit that generates motion data related to a missing target pixel in a subject interlaced video field based on per-pixel motion measurements calculated from neighboring pixels in the subject field, at least one preceding field and at least one subsequent field, a video processing unit selects and utilizes at least one de-interlacing method to determine a value for the missing target pixel based on the related motion data, and at least one lookup table accessible to the video processing unit that correlates motion data to at least one of the plurality of de-interlacing methods.
