Paper document processing apparatus, paper document processing method, and computer readable medium

1. A paper document processing apparatus comprising:

a document image acceptance unit that accepts a document image acquired by scanning a paper document;

a document image recording unit that records the document image and identification information in a storage, the identification information relating to the document image;

an attribute information acquisition unit that acquires attribute information written in letters on the paper document by a first recognition method from a first image generated by a first image process performed on the document image;

an acquisition result evaluation unit that evaluates whether an acquisition result of the attribute information acquired by the attribute information acquisition unit is affirmative or negative;

a partial execution unit that, at a point in time when the acquisition result is negative, acquires attribute information by a second recognition method from a second image generated by a second image process performed on the first image, wherein the second recognition method is different from the first recognition method and the second image process generates the second image through the processing of information displayed in the first image;

a medium output unit that outputs a medium on which the identification information and the second image are printed;

a medium acceptance unit that accepts the identification information and second image printed on the medium by scanning the medium; and

an attribute information reacquisition unit that reacquires the attribute information of the paper document from the second image scanned by the medium acceptance unit.

2. The paper document processing apparatus as claimed in claim 1 , further comprising:

an execution result evaluation unit that evaluates whether an execution result of the attribute information acquired by the partial execution unit is affirmative or negative.

3. The paper document processing apparatus as claimed in claim 2 ,

wherein

the medium outputted by the medium output unit indicates the execution result of the partial execution unit, and

the attribute information reacquisition unit acquires the execution result indicated by the medium.

4. The paper document processing apparatus as claimed in claim 2 , further comprising:

an execution result recording unit that records the execution result of the partial execution unit in the storage.

5. The paper document processing apparatus as claimed in claim 1 ,

wherein

the first image process generates the first image by removing information displayed in the document image.

6. A paper document processing method comprising:

accepting a document image acquired by scanning a paper document;

recording the accepted document image and identification information in a storage, the identification information relating to the document image;

acquiring attribute information written in letters on the paper document by a first recognition method from a first image generated by a first image process performed on the document image;

evaluating whether an acquisition result of the acquired attribute information from the first image is affirmative or negative;

at a point in time when the acquisition result is evaluated negative:

acquiring attribute information by a second recognition method from a second image generated by a second image process performed on the first image, wherein the second recognition method is different from the first recognition method and the second image process generates the second image through the processing of information displayed in the first image;

outputting a medium on which the identification information and a second image are printed;

accepting the identification information and second image printed on the medium by scanning the medium; and

reacquiring the attribute information of the paper document from the second image printed on the medium.

7. The paper document processing method as claimed in claim 6 ,

wherein

the first image process generates the first image by removing information displayed in the document image.

8. The paper document processing method as claimed in claim 6 , further comprising:

evaluating whether an execution result of the attribute information reacquired from the second image is affirmative or negative.

9. A non-transitory computer readable medium storing a program causing a computer to execute a process for reading images of various kinds of paper documents existing in large quantities, the process comprising:

accepting a document image acquired by scanning a paper document;

recording the accepted document image and identification information in a storage, the identification information relating to the document image;

acquiring attribute information written in letters on the paper document by a first recognition method from a first image generated by a first image process performed on the document image;

evaluating whether an acquisition result of the acquired attribute information from the first image is affirmative or negative;

at a point in time when the acquisition result is evaluated negative:

acquiring attribute information by a second recognition method from a second image generated by a second image process performed on the first image, wherein the second recognition method is different from the first recognition method and the second image process generates the second image through the processing of information displayed in the first image;

outputting a medium on which the identification information and a second image are printed;

accepting the identification information and second image printed on the medium by scanning the medium; and

reacquiring the attribute information of the paper document from the second image printed on the medium.

10. The non-transitory computer readable medium as claimed in claim 9 ,

wherein

the first image process generates the first image by removing information displayed in the document image.

11. The non-transitory computer readable medium as claimed in claim 9 , wherein the process further comprises:

evaluating whether an execution result of the attribute information reacquired from the second image is affirmative or negative.
