Patent ID: 8223264

Claim:
A method for deinterlacing a picture, comprising the steps of: (A) determining a protection condition by performing a static check on said picture in a region around a location interlaced with a field of said picture; (B) evaluating said region for a stationary horizontal edge in said picture in response to said protection condition concluding that said location is in an area of said picture with motion; (C) searching for another edge in said picture proximate said location in response to not finding said stationary horizontal edge; (D) calculating an interpolated sample at said location by vertically filtering said field using a first tap filter having a first number of taps in response to not finding said other edge; and (E) calculating said interpolated sample by directionally filtering said field along a particular angle corresponding to said other edge using a second tap filter having a second number of taps less than said first number of taps in response to finding said other edge.
