1. A document character reading system, comprising:

  • a first data reading component that reads image data from a recording medium such as a document in which the characters to be read are stored, recognizes first character data from said image data on the basis of a first character recognition method, and outputs said image data and first character data;

    a second data reading component that checks whether said first character data matches second character data recognized from said image data on the basis of a second character recognition method different from said first character recognition method, and outputs said character data as correctly read character data if there is a match, but outputs said first or second character data as incorrect data if there is no match;

    a correction component having a display that receives said image data and incorrect data, and displays said image data as an image and said incorrect data in a character font, for correcting said incorrect data into correct character data while the operator compares the displayed image data and incorrect data;

    a memory component that readably stores image data and first character data from said first data reading component, said second character data, and said correct character data;

    wherein said image data comprises the whole image data of said document and field image data extracted from images within fields where the characters to be read are written; and

    wherein said first character data and second character data are recognized from said field image data.
