Abstract:
1. A magnetic ink character reading apparatus, comprising: a magnetic data acquisition unit configured to acquire magnetic data from a string of magnetic ink characters on a sheet-type medium; a magnetic recognition unit configured to process the magnetic data; an optical recognition unit configured to perform an optical recognition process on character recognition blocks of an image containing the string of magnetic characters, each block containing an image of one magnetic ink character and the character recognition blocks defining a recognition processing area; and a comparison unit configured to compare a first magnetic recognition result obtained from the magnetic recognition unit with a first optical recognition result obtained from the optical recognition unit; wherein, when the comparison unit determines that the first magnetic recognition result and the first optical recognition result differ, the optical recognition unit identifies a re-recognition processing area offset in a substantially perpendicular direction with respect to at least a portion of the recognition processing area and performs the optical recognition process again on each character in the re-recognition processing area.
