ABSTRACT:
A method for interpolating pixel data of an omitted line by use of pixel data from an interlaced scan and an apparatus therefor are described. The pixel interpolation method and apparatus efficiently interpolate edges having various slopes according to a degree of correlation. When an edge has a gentle slope due to extensive correlation, interpolation is performed using a wide-vector. When an error occurs due to high-frequency components such as when bidirectional edges are found, simple vertical interpolation is performed.
