Abstract

A method of creating a dictionary for character recognition uses a document on which identical characters are aligned in a scanning direction and a mark indicating a size of a character line including the characters is positioned in the vicinity of the aligned characters. An image processing is carried out for dot patterns of the aligned characters, and one dot pattern to be registered in a dictionary is produced. Then, the produced dot pattern is registered in a dictionary together with a corresponding character code data.
