Patent ID: 7133556

Claim:
A character recognition device to recognize characters in a captured text image, comprising: a first recognition unit to recognize the characters in the text image using a first character recognition algorithm; a second recognition unit to recognize the characters in the text image using a second character recognition algorithm different from the first character recognition algorithm, where each character recognition algorithm produces a first and a second character recognition result, respectively, including recognized characters from the same text image; an extraction unit to extract a location from the different algorithm first and second character recognition results where character recognitions from the different algorithm first and second character recognition results do not coincide with each other, wherein if the extracted non-coinciding location has a different number of recognized characters, to output at the extracted non-coinciding location recognized characters based upon either the first character recognition result or the second character recognition result according to a prescribed standard, and wherein if the extracted non-coinciding location has a same number of recognized characters, to output at the extracted non-coinciding location recognized characters with a higher evaluation value according to the first and second character recognition results; and an output unit to output the recognized characters while designating the extracted non-coinciding location of the non-coinciding character recognitions by the first and second character recognition algorithms.
