DCDi (Directional Correlation Deinterlacing) is a digital enhancement method developed by Faroudja in 1996. 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.
