Information processing apparatus, information processing method, computer readable medium, and computer data signal

An information processing method comprising:

• reading through a scanner an additional write document provided by writing additional write information to an original document in different colors;
• detecting with the scanner color information on the additional write document;
• storing in a storage unit a correspondence table between the color information detected by the scanner and plural used colors contained in the detected color information;
• analyzing with a processing unit the plural used colors based on the detector color information using the correspondence table in the storage unit;
• determining with the processing unit overlap between different colors on the additional write document based on an analysis result obtained by analyzing;
• joining the break of the additional write information corresponding to the correspondence portion between the overlap and the break of the additional write information;
• determining a specification area of the additional write document according to the additional write information joined;
• and
• using OCR to read information contained in the specification area analyzed.

A non-transitory computer readable medium storing a computer readable program for causing a computer to execute a process for executing a document analysis processing, which comprises:

• inputting an additional write document provided by writing additional write information to an original document in different colors;
• acquiring color information on the additional write document;
• analyzing a correspondence between one of a color combination and a color space generated by color mixture and the colors extracted unit based on the colors extracted;
• determining overlap between different colors on the additional write document based on an analysis result obtained by analyzing;
• joining the break of the additional write information corresponding to the correspondence portion between the overlap and the break of the additional write information;
• determining a specification area of the additional write document according to the additional write information joined;
• and
• reading information contained in the specification area analyzed.
