Abstract:
At a preliminary stage, a compressing unit generates frequency information, outputs a compression code associated with a piece of first data of the longest matching character string among the pieces of first data contained in the frequency information, when the longest matching character string has a length smaller than the predetermined length and outputs a compression code associated with a piece of position information matching with position information about the longest matching character string among the pieces of position information about the second data contained in the frequency information and a compression code associated with length information about the longest matching character string among the pieces of first data contained in the frequency information, when the longest matching character string has a length equal to or larger than the predetermined length.
