Abstract
A data compression apparatus includes a lossless compression unit performing lossless compression of each data unit of original data to be compressed to output compressed data; a measuring unit measuring a data amount of the compressed data; and a generating unit generating and outputting compression result management data indicating a result of the compression of each data unit of the original data. The generating unit records data indicating a range of the original data of the data unit if the data amount of the compressed data is larger than or equal to the data amount of the data unit before completion of the lossless compression. The generating unit records data indicating a range of the compressed data of the data unit if the data amount of the compressed data is smaller than the data amount of the data unit upon completion of the lossless compression of the data unit.
