Summary:PURPOSE:To suppress the influence of noise and to highly accurately recognize a character by executing the determinate processing of a recognized result based upon word information, judging whether an undeterminate character is noise or not and disregarding character judged as noise. CONSTITUTION:A document to be recognized is inputted and stored in an image storing means 13 as a binarized document image. A letter rectangle detecting means 14 finds out a rectangle circumscribed to a letter and stores the coordinate data of the rectangle and a serial number in a letter rectangle coordinate storing means 15. A word segmenting means 16 finds out a letter rectangle constituting a word and stores the serial numbers at every word in a word letter rectangle means 17. A letter pattern sorting means 18 superposes letters in the character image, sorts the letters in each same letter sort, a letter recognizing means 21 recognizes a sorted letter group and a recognized result defining means 24 defines the recognized result. Then the existence of noise is judged by the positional relation and size of the undeterminate letter rectangle and the letter judged as the noise is disregarded to obtain the recognized result.
