Abstract:
1. An image decoding method of decoding an image from a coded stream in which the image is coded, said image decoding method comprising: decoding a first parameter from a sequence parameter set in the coded stream, the first parameter indicating a first bit-depth that is a bit-depth of a reconstructed sample in the images; decoding a second parameter different from the first parameter from the sequence parameter set, the second parameter indicating a second bit-depth that is a bit-depth of an Intra Pulse Code Modulation (IPCM) luma sample in the image when the IPCM luma sample is included in the coded stream; and decoding a third parameter different from one of the first parameter and the second parameter from the sequence parameter set, the third parameter indicating a third bit-depth that is a bit-depth of an IPCM chroma sample in the image when the IPCM chroma sample is included in the coded stream.
