ABSTRACT:
A chroma format conversion method that determines whether chroma format data to be converted is interlaced data or not. When the chroma format data is non-interlaced data the chroma format data is converted using a filter for non-interlaced. When the chroma format data is interlaced data it is determined whether the chroma format data is odd field data or even field data. When the chroma format data is odd field data the chroma format data is converted using a filter for odd field and when the chroma format data is even field data the chroma format data is converted using a filter for even field.
