Abstract
A method for deinterlacing a picture is disclosed. The method generally includes the steps of (A) calculating a potential sample at a location interfaced with a first field of the picture by temporal filtering, (B) evaluating a protection condition in a current region around the location after inclusion of the potential sample and (C) calculating an interpolated sample at the location by vertical spatial filtering the first field in response to the protection condition indicating a significant increase in a vertical activity within the current region due to the potential sample.
