A dividing unit divides respective symbol sequences of input data applied with zigzag scan and a run-length process into a plurality of subsets having similar frequencies of occurrence, depending on a difference in frequencies of occurrence. A table creating unit scans each subset and creates a Huffman coding table for each subset. A coding unit executes a process for performing Huffman coding on each subset by using the Huffman coding table created for the subset, for all of the subsets in the plurality of subsets.
