Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of searching a stored document and displaying it on a screen in a document image filing system or the like.

[Conventional technology]

2. Description of the Related Art Conventionally, in a document image filing system or the like, a document image of a search result is displayed on a screen of a terminal in a state of being stored at the time of registration. Also, if there are multiple pages of search results, if you do not carefully read the contents of the displayed document image,
I do not know what classification each document image is. A related device of this type is disclosed, for example, in Japanese Patent Laid-Open No. 58-84365. However, these functions alone are not enough to efficiently search for only a desired object from the document images stored in the filling system.

Specifically, it was difficult to know when the displayed document image was registered just by looking at the displayed document. Further, when displaying a document image of a plurality of pages, it is not clear just by looking at the displayed document where the table of contents and the text are up to the text. In addition, unless some sort processing is performed on the document images on the plurality of pages searched and displayed, the processing of the document images of the plurality of pages having the same condition cannot be performed. For example, processing such as viewing only the page of the drawing in the patent specification cannot be performed.

Therefore, at the present time, when a document is searched for by an image, the filing on paper is more efficient.

[Problems to be solved by the invention]

When searching for a document image of a plurality of pages, the above prior art does not consider a display method utilizing information of the document image in advance at the time of registration. There was a problem in searching for ease of use.

A first object of the present invention is to display a background image for one item of the content of the search information based on the search information which the document image has in advance at the time of registration when displaying the searched document images of a plurality of pages. By setting and displaying the document image with the set background color, the search information such as bibliographic items of the document image can be understood at a glance.

A second object of the present invention is to perform display processing on a document image having a background color in a retrieved multi-page document image when the document image has a background color according to the first object. To enable easy-to-use search.

[Means for solving the problem]

The above-mentioned problem is to set a background color of the retrieved document image determined in advance at the time of registration based on search information of the document image and a current search environment in which the document image is being searched, and set the document image to that setting. This can be achieved by coloring and displaying the background color. The search environment is, for example, the current date and time (year), a searcher, and the like.

Further, it is achieved by performing display processing on a document image having a certain background color among the set background colors.
