Abstract
An apparatus to compress a binary image includes a symbol dividing unit to extract at least one symbol from a binary image and to output the extracted symbol and a residue image, a symbol matching encoding unit to perform a symbol matching encoding operation on the extracted symbol, to determine an encoding mode according to a result of the symbol matching operation, and to output symbol matching encoded data and encoding mode information corresponding to the encoding mode, a first encoding unit to perform a bit-based encoding operation on the binary image or the residue image based on the encoding mode information and to output bit-based encoded data, and a bitstream output unit to output the bit-based encoded data of the first encoding unit as a bitstream, or to collect the bit-based encoded data of the first encoding unit and the symbol matching encoded data of the symbol matching unit and to output the collected data as the bitstream, based on the encoding mode information, and a method thereof.
