Abstract
A specifying unit specifies one or more dividing positions in input data. A common region compressing unit specifies compression positions in the input data corresponding to positions at which sizes from two ends of compressed, data are equal to or larger than a predetermined, size and corresponding to positions which sandwich adjacently-positioned dividing positions and of which a size therebetween is equal to or larger than the predetermined size and compresses former compression data that are arranged in a row in the input data on either side of each of the dividing positions and that are interposed between the compression positions. An individual region compressing unit compresses latter compression data that are separated fay any of the pieces of former compression data in the input data, based on the former compression data positioned adjacent to the piece of latter compression data and the piece of latter compression data.
