Abstract: PURPOSE:To properly perform the post processing of character recognition. CONSTITUTION:A document image 2 is segmented into individual character images by a character segmenting part 3, and a character code is outputted from a character recognition part 4 by pattern recognition. Meanwhile, a standard character space between characters in the document image 2 is calculated in a standard character space calculating part 51 by segmenting information obtained by the character segmenting part 3. A character space calculating part 52 divides each character space by this standard character space to calculate a normalized character space. A character space collating part 54 compares this normalized character space with a prescribed value stored in character segmenting knowledge data 53; and if it is smaller than the prescribed value, adjacent characters are regarded as one character. A language knowledge collating part 6 substitutes a part, which is discriminated as segmenting error by a character segmenting error detection part 5, out of the character code inputted from the character recognition part 4 with a character code in character segmenting knowledge data 53 inputted through the character space collating part 54. This substituted character code is used to perform collation with a word dictionary 7.
