PURPOSE: A motion adaptive de-interlacing method and an apparatus are provided to generate an interpolated pixel at a vertical position in a field of a video frame by de-interlacing corresponding to motion. CONSTITUTION: A method comprises the steps of receiving at least two pixels vertically adjacent to the vertical position in the field of a video frame and at least three pixels from at least one adjacent field, detecting a degree of motion in the vicinity of the interpolated pixel, providing weighting factors based on the degree of motion, and calculating the interpolated pixel based on a combination of weighted contributions from the at least two pixels and the at least three pixels. The weighted contributions are derived from a combination of the weighting factors and at least vertical-temporal and temporal interpolation. For at least one degree of the motion, the weighted contributions comprise a first positive contribution derived from immediately adjacent ones of at least two pixels, a second positive contribution derived from a central one of at least three pixels located at the vertical position, and a negative contribution derived from two of at least three pixels that are immediately vertically adjacent to the central pixel.
