Zusammenfassung:	PURPOSE: A de-interlacing apparatus using an adaptive weighted value and method thereof are provided to reduce processing time and a deterioration phenomenon using an FDIF(Fixed Directional Interpolation Filter). CONSTITUTION: An edge direction detection unit detects the direction of an edge. A pixel interpolation unit applies filter coefficient fixed in an FDIF as a weighted value to one or more adjacent pixels based on the detected direction. The FDIF indicates a since function characteristic. The pixel interpolation unit applies an additional weighted value according to a vertical direction. The additional weighted value is extracted by considering of a correlation between the pixels.
