  In recent years, there is a technique in which document image data digitized by scanning or the like is accumulated, and a necessary portion of data is cut out from the document image data using an editing application or the like. For example, Patent Document 1 discloses a technique for selecting a desired document element from a scanned document image, and importing and editing the selected document element into document editing software. Patent Document 2 discloses a technique for copying a desired document element (sentence, figure) from a scanned document image to mail by drag and drop.

  Patent Document 3 discloses a technique for decomposing document image data for each document element, coloring and margining according to the document element, and generating an output image. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for photographing a document with a mobile phone camera and converting characters in the photographed document into an appropriate image as a pictograph that can be used for e-mail or the like.

  However, in the invention described in Patent Document 1, the selected and cut-out image is directly taken into the document editing software. For this reason, when a background area is included in the cut-out image, the document editing software is captured while the background area remains, and the background area may not be applied to a newly edited document, and the appearance may be impaired. .

  In the invention described in Patent Document 2, a large number of objects are generated from an input image, and replication can be performed while maintaining the object structure only for the selection range. Therefore, in the invention described in the cited document 2, it is possible to select a capturing form such as only the foreground, the foreground and the background, but it is inefficient to take such a process even when editing of the hierarchical object is not necessary.

  In addition, the invention described in Patent Document 3 describes that a new background color and its area are provided around a document element in a method of printing a paper document described in black and white. It is necessary to manage the table that stores the correspondence between parameters. Further, since an identifier having a logical meaning is used, complicated analysis is required. Further, in the invention described in Patent Document 3, the completed image is an original black and white paper original in color, and does not meet the demand for using only desired document elements with the document editing software.

  The invention described in Patent Document 4 is limited to portable terminals and cannot be applied to document editing or the like using a scanner capable of scanning at a high resolution and a personal computer (hereinafter, PC). In the invention described in Patent Document 4, the object of processing is limited to a character portion (character and its background).
