Abstract

PURPOSE:To shorten a retrieving time by retrieving a document based on a document retrieving key word, thereafter, designating the attribute information of respective pictures constituting the document, and contracting the picture based on the designated attribute information. CONSTITUTION:An input part 1 contracts the picture by an attribute information designating means for designating the attribute information of the respective pictures constituting the prescribed document after the retrieval is executed and a processing part 2 contracts the picture based on the designated attribute information after the retrieval is executed. Namely, since after the document is retrieved based on the document retrieving key word, the attribute information of the respective pictures constituting the document is designated and the picture is contracted based on the designated attribute information, the document can be easily retrieved even when the desired page of the desired picture cannot be clearly recognized to shorten the retrieving time.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention stores documents as image data, searches for a desired document based on a document search keyword attached to the document, and displays a document image. It relates to a processing device.

[Prior Art] A conventional document image processing device searches for a desired document based on a document search keyword set at the time of storage, displays the first page of the desired document on a display unit, and sequentially scrolls through the pages. By turning the page or directly specifying the page, the image of the desired page is displayed on the display section.

[Problems to be Solved by the Invention] The above-mentioned conventional device uses a document keyword search function as a means for searching and displaying a desired page of a desired document;
It only has a page turning function and a page designation function. For this reason, if it is not possible to clearly recognize the desired page of a desired document, the user has no choice but to search by turning the pages one by one, resulting in a problem that the search takes a lot of time.

[Means for Solving the Problems] The present invention specifies attribute information of each image constituting the document after searching for a document based on a document search keyword,
Images are narrowed down based on the specified attribute information.

[Operation] The present invention specifies attribute information of each image constituting one document after searching for a document based on a document search keyword,
Since the images are narrowed down based on the specified attribute information, even if it is not clear which page the desired image is, it can be easily searched, and the search time is shortened.

[Example] FIG. 1 is a block diagram showing one embodiment of the present invention.

This embodiment includes an input section 1 for inputting data, a processing section 2 for processing data, a storage section 3 for storing information such as documents input from the input section 1, and a storage section 3 for storing information such as documents input from the input section 1. A display unit 4 that displays information on documents etc. or processing results
and a processing section 5 that outputs the data processed by the processing section 2.

The input unit l includes an image reader 4, a keyboard 15, and a pointing device 16, and includes an image reader 4, a keyboard 15, and a pointing device 16.
4 converts the read image into a digital signal and stores it on the optical disc 12. The keyboard 15 is used to input keywords for document retrieval and data processing commands. The pointing device 16 is used to input coordinate information on the display 17.

The input unit 1 inputs attribute information of each image constituting a predetermined document.
This is an example of attribute information specifying means specified after executing a search. Further, the processing unit 2 is an example of an image narrowing unit that narrows down images based on the specified attribute information after executing the above search.

The storage unit 3 includes a memory 11, an optical disk 12, and a hard disk 13. The memory 11 stores document image data stored on the optical disk 12,
It is used to temporarily store record information stored in . The hard disk 13 stores keyword information necessary for document retrieval and information about pages constituting a document, and the optical disk 12 is of a write-once type and can store a large amount of document image data.

The laser beam printer 18 constituting the output section 5 is used for high resolution image formation.

FIGS. 2 and 3 are diagrams for explaining the file structure of the hard disk 13 in the above embodiment.

The document management file 21 shown in FIG.
1a and the address 21b of the first page are stored.

The keyword 21a records a search keyword attached to each document. The address 21b of the first page contains the page management file 3 in which management information for the page of the document is recorded.
1 (shown in FIG. 3) stores the record address.

The page management file 31 shown in FIG.
The 0-page management file 31, which stores a, page 31b, image mode 31c, size 31d, density 31e, image storage position 31f, and next page chain address 31g, contains page address 31a, page 31b, image mode 31c, The size 31d, the density 31e, and the image storage position 1i31f form one record, and this one record manages information for one page of the document.

Here, page 31b indicates which page of the document the page record is. When reading an image from the image reader 14, the image mode is 31c, the size is 31d, and the density is 31.
The one-image mode 31c in which e is set means the image quality of the image, which can be broadly divided into text images and photographic images. size 3
1d indicates the size of an image when one image is read, and in the above embodiment, it indicates a standard size such as A4 or B5.

The density 31e indicates the reading density of the image, and is 1
The 0 image storage position 31f, which is expressed in dots per inch, is the address of the image stored on the optical disc 12, and is the chain address of the 0 next page stored as the address of the first sector and the last sector. 31g
If there is a page to continue next, and the content of the chain address 3.1g of the 0th page, which is the address of the record where the information of the next page is stored, is rFFJ, it means that there is no next page. This means that the record is information on the last page of the document.

FIG. 4 is a diagram showing an example of a case where the search results are displayed as a list on the day 5 play 17.

In the search result list) 41, the keywords 21a of the documents searched under the conditions specified by the operator are displayed in order.The image attribute specification window 42 displays the image attribute display area 4.
2a and an image attribute specification input area 42b, an image mode 31c, size 31d, and density 31e are displayed, and a specified value input area 4
A cursor 42c is displayed at 0b so that each attribute can be input.

FIG. 5 is a diagram showing a state in which an image 51 is displayed on the display 17.

Previous page〈If you specify the refunction 52a with the pointing device 16, one of the currently displayed images
Display the previous page image. Further, when the next page turning function 52b is designated by the pointing device 16, the image one page after the currently displayed image is displayed.

Next, the operation of the above embodiment will be explained.

FIG. 6 is a flowchart showing the operation of the above embodiment.

First, perform a search using the search conditions specified by the operator,
The results are displayed on the display 17 as a search result list shown in FIG. When specifying the desired document using the pointing device 16 or keyboard 15 (B2) and inputting image attributes, it is also possible to input only the necessary attributes. Furthermore, multiple inputs may be made for one image attribute.

In this case, it is sufficient that one of the multiple designated image attributes matches. The image contents of Sl and B2 are shown in FIG.

Set the page number n to 1 (33) in order to find a page that matches the specified image attribute among each page of the document specified in B2, and use the page management file 31 to know the image attribute of the nth page. Reads the content of the nth page from the page and determines whether it matches the image attribute specified by the operator in B2 (B4)
, If it is determined that the image does not match, judge whether the image is the last page or not (B5). If it is not the last page, select n to see if the next page matches or not. Increment by 1 (B6). Then return to B4.

If it is determined in B5 that this is the last page, there is no image in the document specified by the operator that has an image attribute that matches the image attribute specified by the operator, and a message saying "No corresponding image" is displayed. Display the message (37), then return to step 32. When returning to step 52, the input value of the one image attribute is displayed as is, so if another document is selected as is, the search process is executed for the other document based on the previously specified image attribute.

If the image attribute in the page record of the n-th page matches the specified image attribute at B4, a table of that page record is created in the memory 11 (B8).

Thereafter, based on the image storage position in the page record, the image is read out from the optical image display 12 and displayed on the display 17 (39).

The operator must determine whether the displayed image is the desired image or not. If it is not the desired image, the operator must decide whether to continue the process by turning the page or to end the process by specifying "End". The operator decides (S11)
, if end is specified, the process returns to S2.

When performing page turning, specify previous page turning (52a) or next page turning (52b) (S12
), if the next page turn is specified, the process returns to S6. If previous page turning is specified, the page record contents of the image immediately before the currently displayed image are read from the table created in S8 (S13), and if the previous page exists, If the page does not exist (S14), the image is displayed (S9), and if the page does not exist, the process returns to step 37.

At 310, if the operator determines that the desired image has been displayed, the above operation ends.

In the above example, the image attributes are specified after executing the search and displaying the search result list, but image attributes can also be specified at the same time before executing the search (i.e., when specifying the search conditions). In this case, the search may take some time, but since the table creation shown in FIG. 6 58 of the embodiment of the present invention is executed at the time of the search, the image display after document search and the image display when turning pages becomes faster. In addition, only documents that match the specified search conditions and have pages with the specified image attributes are displayed in the search result list, making the search more efficient if the attributes of the desired image are clear. .

[Effects of the Invention] According to the present invention, in a document image processing device that stores a document as image data, searches for and displays a desired document based on a document search keyword attached to the document,
Even when it is not possible to clearly recognize the desired page of a desired document, it can be easily searched and the search time is shortened.
