Abstract
In the encoding method, a first frame is obtained as the object to be encoded (step S13101). The first data containing one or more levels in the first frame is encoded by referring to the second data containing one or more levels in the second frame (step S13102). When encoding the first data, for each of the one or more levels of the first data, a value representing the corresponding level and a value related to the one or more levels of the second data are used to determine one of the multiple processes, and the determined one process is performed on the first data of the corresponding level.
