1. A method of converting an interlace scan video image to a progressive scan video image, comprising the steps of: (a) determining whether a target picture element (pixel) position of an interpolated row of pixels lies on an edge between visually distinct regions; (b) determining a degree of movement in the region of the target pixel position between a previously displayed image and the interlace scan image; (c) generating a plurality of potential values for an interpolated pixel at the target pixel position; and (d) selecting at least one potential value from the plurality of potential values for the interpolated pixel responsive to the determination of whether said target pixel position lies on an edge and the determined degree of movement in the region of the target pixel position.
