PICTURE ENCODING METHOD AND APPARATUS, PICTURE DECODING METHOD AND APPARATUS AND FURNISHING MEDIUM |
摘要 |
The MPEG4 is expanded to permit the use of the 4:2:2 format and the 4:4:4 format. To this end, there is provided an encoder adapted for encoding a picture in terms of a macro-block made up of a block of luminance Y and a block of chrominance Cr, Cb. The encoder includes a VOP encoding unit 3 for encoding the picture as reading of a flag (cbpc) specifying the state of encoding of the chrominance block and a flag (cbpcb, cbpcr) specifying the state of encoding of the chrominance block associated with the types of the chrominance Cb, Cr is adaptively changed responsive to a flag (chroma_type) representing the chrominance format of the picture and to the flag (cbpc) specifying the state of encoding of the chrominance block.
