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

摘要

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.
