(Directional Correlation Deinterlacing) is a digital
enhancement method developed by Faroudja
. DCDi technology is primarily used for improving the image quality of low resolution
images. This is done by deinterlacing
the image and blending rough edges occurring in diagonal lines. The technique is often used in LCD
and plasma television
sets. DCDi technology is also present in the Sage FLI2200
chip, which is used in many DVD players.
