Device for and method of coding/decoding image information

摘要

A device for coding image information, which is a shape encoder for splitting an image transferred from an image input into an object image and a background image that have predetermined shape information, includes: a boundary block merge block for merging boundary blocks including both the object and background images out of shape information received, by using a boundary block merge technique; a variable length coding block for variable-length-coding the merged boundary blocks received from the boundary block merge block; and a variable length coding table memory for storing variable length coding tables which are used when the merged boundary blocks are variable-length-coded by the variable length coding block.
