Abstract
A system and method for generating an interpolated pixel at a vertical position in a field of a video frame. The method comprises the steps of receiving at least two pixels vertically adjacent the vertical position in the field 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 said motion, the weighted contributions comprise at least (i) a first positive contribution derived from immediately adjacent ones of the at least two pixels, (ii) a second positive contribution derived from a central one of the at least three pixels located at the vertical position, and (iii) a negative contribution derived from the two of the at least three pixels that are immediately vertically adjacent the central pixel.
