摘要：
The image coding method can improve coding efficiency by using an adaptive bit-depth. The image coding method is used to code images to generate a coded stream. The image coding method includes: writing (S1001), into a sequence parameter set in the coded stream to be generated, a first parameter representing a first bit-depth that is a bit-depth of a reconstructed sample in the images; and writing (S1002), into the sequence parameter set, a second parameter which is different from the first parameter and represents a second bit-depth that is a bit-depth of an Intra Pulse Code Modulation (IPCM) sample in the images.
