A character recognition system extracts character blocks to contain a minimum character unit therein. The character recognition system has a capability of re-combining and/or re-extracting character blocks during the character recognition process. Recombination and re-extraction of the character blocks is controlled based on the extraction histories of each of the character blocks so that re-combination and reexraction can be performed effectively.
