US 8,553,155 B2 · System and method for three dimensional comb filtering

Abstract

A system and method for improved comb filtering. Various aspects of the present invention may comprise method steps and system components that generate a signal indicative of the quality of a field-combed signal. A first signal indicative of inter-field and inter-line signal difference substantially inside the chroma frequency band may be generated. An indication of field comb quality may be determined based at least in-part on the first signal, and a corresponding signal may be generated. Various aspects of the present invention may comprise method steps and system components that generate a comb-filtered signal. A field comb signal and line comb signal may be generated. A comb-filtered signal may be generated based on the field comb signal, line comb signal, and the signal indicative of the field comb quality.
