ABSTRACT:
A first compression unit compresses input data by a first compression method utilizing a dictionary coding method. A second decompression unit compresses input data by a second compression method utilizing a statistical coding method. A size calculation/determination unit pre-calculates sizes of data to be output when the data is compressed only by the first compression method, when the data is compressed only by the second compression method, when the data is compressed both by the first and second compression methods, and when the data is compressed neither by the first nor the second compression method, and selects the method that will result in the smallest data size, so that the input data is compressed by the selected method.
