Abstract
Disclosed are an image coding and decoding methods, an image processing device, and a computer storage medium. The image coding method comprises: obtaining a dynamic range of a copy parameter of a current coding sampling value segment according to a size of a reference area; and coding the copy parameter according to the dynamic range to generate a video bitstream containing information about the size of the reference area and information about the copy parameter. The decoding method comprises: parsing a video bitstream to obtain a dynamic range of a copy parameter of a decoding sampling value segment; and decoding the copy parameter according to the dynamic range.
