摘要

PPROBLEM TO BE SOLVED: To provide a compression data structure capable of compressing characteristic data and storing it in a fixed-length data area, irrespective of the content of the characteristic data. PSOLUTION: A data structure used for a compressed characteristic data 24 comprises a fixed-length characteristic data region 24a. The fixed-length characteristic data region 24a stores a plurality of difference data having difference value calculated from two second two numeric values in two pair data adjacent on a first numeric value, in a series of pair data constituting characteristic data. The data structure stores a difference value judged that it can be represented by a first bit length in the characteristic data region 24a as difference data of the first bit length, and stores a difference value determined that it cannot be represented by the first bit length but represented by a second bit length in the characteristic data area 24a as difference data of the second bit length.

要解决的问题：提供一种压缩数据结构，该压缩数据结构能够压缩特征数据并将其存储在固定长度的数据区域中，而与特征数据的内容无关。解决方案：用于压缩特征数据24的数据结构包括固定长度特征数据区域24a。固定长度特征数据区域24a在构成特征数据的一系列配对数据中，存储多个差分数据，该差分数据具有根据两个第二两个数值计算出的差值，该差分值是在与第一数值相邻的两个配对数据中。数据结构在特征数据区域24a中存储被判断为可以由第一位长度表示的差值作为第一位长度的差数据，并且存储确定为不能由第一位长度表示但是可以确定的差值。在特征数据区24a中由第二位长表示的第二位长表示为第二位长的差数据。
