  • Patent number: 7899112
    Abstract: A method and apparatus for extracting chrominance shape information for an interlaced scan type image, which are used in a video compression coding/decoding system or a video manipulation equipment/system. According to the present invention, in an interlaced scan type image with arbitrary luminance shape information, chrominance shape information is extracted on the basis of four adjacent luminance shape pixels in two lines of the same type field. The present method and apparatus can solve a color bleeding problem in a conventional chrominance shape information extraction method considering no characteristic of the interlaced scan type image. Therefore, the present invention has the effect of significantly improving subjective picture quality.
