1. A method of intra-field de-interlacing, comprising: performing a coarse estimation to eliminate at least one direction from a set of edge candidate directions that extend from a pixel being interpolated, without directly evaluating each direction; after performing the coarse estimation, performing a fine estimation in which a set of remaining candidate directions are evaluated to select a single direction as corresponding to an edge; and performing a directional interpolation as a function of the single selected direction to generate a pixel value for the pixel being interpolated.
