A character string of which a start point is each address of character string data in an input buffer is rearranged in the predetermined order, so that a rank list is generated. Next, the location of the matching candidate of a character string to be encoded is obtained on the basis of the rank list. Then, the character string to be encoded is compared with a matching candidate, thereby obtaining a matching length. Further, a code is generated using the location of the matching candidate and the matching length, and the code is output as compression data.
