DECODING METHOD, ENCODER, AND DECODER

摘要

A decoding method, an encoder, and a decoder are provided. The decoding method includes, in a palette mode, determining a state value of a flag corresponding to the coding unit block; if the flag is a first state value, determining that an amount of indexes corresponding to the coding unit block is an amount of one or more major colors of the coding unit block; and if the flag is a second state value, determining that the amount of the indexes corresponding to the coding unit block is the amount of the one or more major colors of the coding unit block plus one.
