Document information managing apparatus and computer readable medium

1. A document information managing apparatus comprising:

a storage that stores a first reference image generated from an original document, and paper size information of the original document, the first reference image having a size proportional to a paper size of the original document;

a producing unit that produces a second reference image in relation to the original document when the paper size of the original document is larger than a predetermined size;

a display determining unit that displays the first reference image where the paper size is smaller than the predetermined size on a display, and that displays the second reference image where the paper size is larger than the predetermined size on the display, wherein,

in response to a selection of the second reference image, the display determining unit displays the first reference image that corresponds to the selected second reference image at a position where the second reference image is displayed,

the storage further includes a first magnification, a second magnification, and a relationship between a name of the paper size and an output size of the paper size,

the first reference image is generated based on the first magnification,

the producing unit produces the second reference image based on the second magnification, and

the second magnification is smaller than the first magnification.

2. The document information managing apparatus as claimed in claim 1 ,

wherein,

in the case that the second reference image is selected, the display determining unit controls the display to display the first reference image related to the second reference image.

3. The document information managing apparatus as claimed in claim 2 ,

wherein

the display determining unit controls the display to display the first reference image that is correlated to the selected second reference image in a different display mode.

4. A document information managing apparatus comprising:

a storage that stores document information and a first reference image in correspondence with each other, the first reference image being formed by changing a size of an output image of the document information based upon first magnification;

a producing unit that produces a second reference image having a size changed based upon second magnification smaller than the first magnification in relation to the document information in a case where the size of the output image of the document information is larger than a predetermined size;

a display that displays the first reference image in a case where the size of the output image of the document information is smaller than the predetermined size, and that displays the second reference image in the case that the size of the output image of the document information is larger than the predetermined size; and

a display determining unit that, in a case where any one of the first reference image and the second reference image is selected, controls the display to display the first reference image correlated to the second reference image, wherein

displaying the first reference image correlated to the second reference image includes displaying the first reference image and the second reference image in a super imposed manner.

5. The document information managing apparatus as claimed in claim 4 ,

wherein,

in the case that the display determining unit satisfies a predetermined condition, the display determining unit controls the display to display the first reference image correlated to the second reference image.

6. The document information managing apparatus as claimed in claim 5 ,

wherein

the predetermined condition implies that a difference between a size of an output image of first document information corresponding to any one of the selected first reference image and the selected second reference image, and a size of an output image of a second document information other than the first document information is larger than a predetermined value.

7. The document information managing apparatus as claimed in claim 6 ,

wherein

the second document information is document information corresponding to any one of the selected first reference image and the selected second reference image, or is document information which is present in the same storage area storing the document information corresponding to the selected first reference image.

8. A non-transitory computer readable medium storing a program causing a computer to execute a process for managing document information, the process comprising:

storing the document information and a first reference image in correspondence with each other, the first reference image being formed by changing a size of an output image of the document information based upon first magnification;

producing a second reference image having a size changed based upon second magnification smaller than the first magnification in relation to the document information in a case where the size of the output image of the document information is larger than a predetermined size;

displaying the first reference image in a case where the size of the output image of the document information is smaller than the predetermined size, and that displaying the second reference image in a case where the size of the output image of the document information is larger than the predetermined size; and

controlling, in a case where the second reference image is selected, the display to display the first reference image relating to the selected second reference image, wherein

displaying the first reference image relating to the selected second reference image includes displaying the first reference image and the selected second reference image in a super imposed manner.

9. The document information managing apparatus according to claim 1 , wherein the display determining unit displays the first reference image in a super imposed manner with the second reference image when the second reference image is selected.

10. The document information managing apparatus according to claim 9 , wherein the display determining unit displays the first reference image in a semi-transparent manner when the second reference image is selected.
