Abstract
Herein described is a method and system for generating an improved video output when deinterlacing pull-down video. The improvement results from reducing cross-chroma artifacts. In a representative embodiment, the method comprises first computing an adjusted chroma of a present pixel from a present top field or present bottom field of film sourced video as a function of an execution stage field phase. The method further comprises second computing a chroma of an absent pixel vertically adjacent to the present pixel, wherein the second computing is performed as a function of the execution stage field phase. In a representative embodiment, a deinterlacer video engine and a local storage circuitry process the 3:2 pull-down video by applying various equations for performing the first computing and the second computing. An adjusted chroma and an absent pixel chroma is computed for each present pixel at each execution stage field phase.
