Abstract

A method of de-interlacing input video information including averaging odd lines and averaging even lines of the input video information to determine first and second in-field information, determining differences between even and odd lines of the input video information to provide residue information, measuring a motion metric of the residue information, filtering the residue information based on the motion metric to provide filtered residue information, and combining the first and second in-field information with the filtered residue information to provide progressive information. The combining may be an average of the in-field information added to a weighted portion of the filtered residue information as determined by the motion metric. The motion metric may be determined by an infinite impulse response filter. Finite impulse response filters may be used to filter the residue information.
