Claims

[Claims for Utility Model Registration] Quantized image data is obtained by photoelectrically converting the feature extraction target on the medium, character patterns of each character are cut out from the image data, and character patterns of multiple fonts prepared in advance are extracted. A character recognition device that recognizes characters by collating an input character pattern using a dictionary including a dictionary mask, comprising: word extraction means for detecting a character string corresponding to a word from a plurality of character patterns; For a given number of characters, a dictionary containing dictionary masks of characters in multiple fonts is selected and used for recognition, and as a result of recognition using the selected dictionary, the font of the dictionary mask with the highest degree of similarity is selected. A character recognition device characterized by comprising: a dictionary selection means that determines the font of the word and selects and uses a dictionary mask of the determined font for characters after the arbitrary number of characters to perform recognition.
