A character recognition device to recognize characters in a text image read by an image scanner having a first recognition device to recognize the characters in the text image using a first character recognition method and a second recognition device to recognize the characters in the text image using a second character recognition method different from the first character recognition method. An extraction device extracts locations of recognized characters in the text image wherein the recognition results of the first recognition device do not coincide with the recognition results of the second recognition device. An output device outputs character recognition results designating the non-coinciding locations extracted by the extraction device.

Character recognition device and method for detecting erroneously read characters, and computer readable medium to implement character recognition

A technology of the present invention is capable of objectively judging an ability of a proofreader who proofreads a digitized document by use OCR programs. A method of managing an ability of a proofreader who proofreads an electronic document generated from a recognition target document by executing a character auto recognition program, comprises a step of estimating a character count of potential mis-recognized characters contained in the electronic document, a step of detecting a mis-recognized character discover count as a mis-recognized character count with which the proofreader discovers the mis-recognized characters in the electronic document, a step of detecting a processing time spent for proofreading the electronic document, and a step of calculating a score relative to a proofreader ability based on a ratio of the potential mis-recognized character count to the mis-recognized character discover count per unit time.
