Abstract
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.
Claims18
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;
- 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 section.
A method of coding information, which is a shape encoding accomplished by splitting an image transferred from an image input 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 method of coding image information, comprising the steps of:
- receiving a plurality of boundary blocks, wherein said boundary blocks comprise object and background images;
- merging said boundary blocks, including both the object and background images, out of shape information received, by using a boundary block merge technique;
- and
- performing a variable length coding according to the result of said merging step.
