Embodiment Construction

[0038] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039]

[0040] figure 1 is a diagram showing the overall configuration of the document processing system of the exemplary embodiment.

[0041] like figure 1 As shown, the system of this exemplary embodiment includes a printing device 100 , a log information holding section 200 , and a retrieval device 300 .

[0042] The printing apparatus 100 generates a document image to be printed, and prints and outputs the document image on a medium such as paper. The printing apparatus 100 is implemented as a printer or a copier. Here, a document image means an electronic image of a document to be printed on a medium. In addition, although the word "document" is used, the content of the document image is not limited to text, so the document image includes only pictures or images generated by computer graphics processing.

Abstract

The document processing system is provided with: a printing unit that prints a document image on a medium; an image reading unit that performs image reading on the medium; a holding unit that holds history information on processing performed by the printing unit; and a search unit that searches the history information held by the holding unit on the basis of an image of a printout which is the medium with the document image printed on the medium by the printing unit. The search unit determines similarity between the image of the printout and a synthetic image in which the document image is synthesized with an image of the medium read by the image reading unit, and searches for history information on processing performed for the printout on the basis of a result of the determination.

Description

technical field [0001] The invention relates to a document processing system, a retrieval device, an information retrieval method and a document processing method. Background technique [0002] In image processing apparatuses such as printers, scanners, facsimile machines, and multifunctional machines integrating these functions, log information (history information) of image processing is stored in memory in some cases. In this case, not only information about the type of processing, when the processing was performed, etc., but also in some cases the image itself on which processing is stored is stored. In this case, electronic images generated (rasterized) in each image processing device are usually accumulated. [0003] If such log information is stored, an image equal to or similar to the printout image can be retrieved in the log information by using the printout image as a key. In this image retrieval, it is necessary to determine the similarity between images. Japa...
