Abstract:
A device for coding image information, which is a shape encoder for splitting an image transferred from an image input unit into an object image and a background image that have predetermined shape information, said predetermined shape information depending upon whether said object image and said background image contains an interior block, an exterior block, or a boundary block:the device for coding image information, comprising:a boundary block merge section for merging boundary blocks including both the object and the background images out of shape information received, by using a boundary block merge technique, said boundary block merge section outputting merged boundary blocks;a variable length coding section for variable-length-coding the merged boundary blocks received from the boundary block merge section; anda 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 section.
