Abstract
A system and a method of adaptively suppressing false-color artifacts are disclosed. A luma spatial frequency unit detects edges or an area with a substantially high luma spatial frequency within an active window, and a chroma spatial frequency unit detects substantial fluctuations in colors within the active window. A false-color detector determines occurrence of false-color artifacts according to results of the luma spatial frequency unit and the chroma spatial frequency unit. A compensator performs compensation on chroma components if the false-color detector decides that the false-color artifacts occur.
