Summary:To assign a code of 2 bytes or more such as a code or the like associated with data that appears frequently to a 1-byte code.SOLUTION: An encoding program encodes input data on the basis of a second code allocation table. The second code allocation table is such that a conversion rule that encodes input data is defined in which a part of data allocated to a 1-byte area of a first code allocation table is allocated to a 2-byte area and a code of 2 bytes or more is allocated to at least a part of the data allocated to the 2-byte area.SELECTED DRAWING: Figure 1 【課題】出現頻度が高いデータに対応付けられたコード等の２バイト以上のコードを１バイトコードに割り当てること。【解決手段】符号化プログラムは、第２コード割当表を基にして、入力されたデータをコード化する。第２コード割当表は、第１コード割当表の１バイト領域に割り当てられたデータの一部が、２バイト領域に割り当てられ、かつ、２バイト領域に割り当てられたデータの少なくとも一部に対して、２バイト以上のコードを割り当てられた、入力されたデータをコード化する変換規則を定義したものである。【選択図】図１
