Abstract

PURPOSE:To improve the retrieval efficiency and to reduce the burden on an operator by retrieving a picture with not only retrieval information but also display attribute information of the set direction, the rotation angle, or the like of the picture. CONSTITUTION:When the control is transferred to a retrieving part 311, the operator is questioned about document data on an optical disk 19 to be retrieved. When the operator inputs an optical disk drive number, the retrieving part 311 reads out the binder name defined in the disk 19 and waits for indication of a binder number. When the operator uses a keyboard 23 or a mouse 29 to indicate the binder number, the document title structure of this binder is obtained from a data base part 52, and a retrieval window RW is displayed on a CRT. Retrieval conditions or the like are inputted to columns of the picture size, the picture direction, the rotation angle, and the page position in accordance with this table.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an image storage device and an image retrieval device such as an image information filing device for registering or searching image information, for example.

(Prior art) In recent years, scanners (
The read image information is stored on an optical disk, the stored arbitrary image information is searched and read out, and it is output to an output device such as a CR.
Image information filing devices that output image information in a form that can be viewed visually on a T-display have been put into practical use.

In such a device, even if the page size, paper direction, rotation angle, etc. of a document are registered in different states, when displaying the retrieved document data on a CRT display, the entire document data ( It has been enlarged and (reduced) to fit on the CRT display. Visually, it appears that the size of the paper is unified across all pages within the document.

Furthermore, when searching for a document, the title of the document registered in advance in the database is used as a keyword.

By the way, in such a device, when searching document data (documents), a search title key stored in the database section is used. In this case, - input search conditions for several dozen title keys per document and search for the corresponding document.

Here, it is assumed that a binder containing multiple documents is to be searched. It is assumed that each document includes a plurality of pages, and each page has a different paper size and paper direction. For example, assume that in a certain document, the -th page is an A4-sized sheet of paper long in portrait orientation, and the second page is a B4-sized sheet of paper stretched horizontally. Here, the search proceeds by specifying the same title as when the requested document was registered.

However, for example, the operator forgot the title for the document, and instead, for example, the last page of the document was on B4 size paper in landscape orientation.
Suppose that the user only remembers the display attributes of the document. In this case, searching by title is of no use to the operator. As a solution, the operator displays -pages of each document in the binder on the screen, for example, displays separate pages, and then searches for a document whose last page is 84 size and registered as landscape. There is a means.

However, it can take a long time to perform such a search on a binder consisting of a large number of documents and pages, and a more efficient search operation means has been desired. Furthermore, it is difficult to display each person in a registered document using the display attributes that were used when the document was registered.

Furthermore, for example, suppose that among the documents to be searched, the difference between the target document and other documents is within a certain area of each purchase within the document. Therefore, it is assumed that the operator has to pay attention to this area and search for the desired document. In such a case, candidate documents are first extracted by inputting the title key as a search condition, and then each member of the candidate branch office is displayed on the screen. Then, for each person displayed, the user pays attention to a certain area in which a clue to the target document exists, and visually checks the area one by one.

In such a method, the operator first finds out where the part of the page that is of interest is located for each person displayed on the screen, and then determines what area the target document has within that area. Two steps are required: determining whether the area has the information you should be in. In this case, as in the above case, it is extremely inefficient to perform such a search on a binder consisting of a large amount of documents and pages, and a more effective search operation means is required.

Therefore, since a search can only be performed using search information, there is a drawback that the search information is forgotten and the search efficiency is poor even if the user knows the display attributes of the desired image.

(Problems to be Solved by the Invention) As mentioned above, since the search could only be performed using search information, there were drawbacks such as forgetting the search information and poor search efficiency even if the display attribute information of the desired image was known. The present invention provides an image storage device and an image retrieval device that can improve search efficiency by not only searching based on search information but also using display attribute information such as image setting direction and rotation angle.

Search and display data (management data) consisting of flags for classifying data or image data, and display attribute information such as image size, image direction, and rotation angle are stored as a database (DB). This search/display data is read from the optical disc 19 and stored when the optical disc 19 is loaded.

The storage address is a logical address, from which a physical track address and a physical sector address are calculated at the time of access.

The magnetic disk device 28 is, for example, a 5.25-inch floppy disk device, and stores text files (document data) created with a word processor (not shown), CAD drawing files, worksheet files (drawing data) created with a personal computer (not shown), etc. This is for reading the code data file from the floppy disk 28a. The above floppy disk 28
As a, those corresponding to various O5s (operating systems) are set.

The document management system in this embodiment has four hierarchies: cabinet, binder, document, and page, as shown in FIG. 2, and the cabinet is associated with one side of the optical disc 19. A maximum of 8 binders can be defined in a cabinet, and a maximum of 30,000 documents can be registered in a binder. Each document has a title, and its structure is defined for each binder. The above-mentioned document is the basic unit of a file, and in addition to the title, annotations (explanatory text for ifs) can be added.

Further, the document is composed of pages up to 4 o 95 pages.

This kind of management system takes into account consistency with paper files, and a page corresponds to one paper file, but in this example, code data is also managed at the level of this page. It is supposed to be done.

That is, the above page can be image data of one sheet of paper, data of one floppy disk (volume-batch data), one file data, or data obtained by merging the above three types.

As a result, for example, in one document, the source file (code data) of a predetermined program, the second page as the first page,
The first page is the program specification (code data) created with a word processor, and the third page is the processing result (image data), which in the past had to be managed completely separately. can be managed. Further, display attribute information is set and managed for each person in the document.

Next, the structure of the control program, ie, software, stored in the main memory 13 will be explained with reference to FIG.

The filing processing section 51 controls the entire system,
This filing processing section 51 includes a search section 311 and a registration section 3.
12, deletion section 313, modification section 314, maintenance section 3
It is composed of 15 t. The database unit 52 stores physical data such as the title of each document, the address and size of the actual data on the optical disk 19, and the image size, image direction, and rotation angle of each member of the document stored on the optical disk 19. It manages display attribute information such as.

The document search information and display attribute information to be stored in the database section 52 are copied from the optical disc 19 when the optical disc 19 is loaded into the apparatus. The document data display unit 53 displays document data in the window of the CRT display 24, and the document data management unit 54
manages each document data stored in the page memory 14. The document data input/output section 55 is connected to an optical disk 19 for recording and reproducing document data, a scanner 20 for inputting document data, a printer 25 for outputting document data, a floppy disk 28a for recording and reproducing code data, and an external device via LAN. It controls document data human output devices such as the BCP 44 that transmits and receives document data between.

The code/image conversion unit 56 converts code data such as CAD data into image data.

When this information processing device is powered on, control first passes to the filing processing section 51, and after each initialization process is performed, the CRT display 24 displays 1: Search, 2: Registration, 3: Delete, Information such as 4: Modification and 5: Maintenance is displayed, prompting the operator to select one of these five processes. When the operator selects one of the displayed information using the keyboard 23 or mouse 29, the filing processing section 51 transfers control to one of the search section 311 to maintenance section 312 depending on the selected information. Ru.

The search unit 311 searches the database unit 52 for document data that satisfies the search conditions input by the operator, and displays a list of corresponding document titles (keywords) on the CRT display 24. Thereafter, when the operator inputs a document title from the keyboard 23, the document data corresponding to this document title is stored in another information processing device (not shown) via the optical disk device 22 or LAN. The optical disc 19 is searched.

This retrieved document data is processed according to the operator's instructions.
displayed on the CRT display 24 or on the printer 25.
printed by. Furthermore, if the retrieved data is code data, processing is performed to output it to the floppy disk 28a.

The registration unit 312 receives document data input from the scanner 20 or the floppy disk 28 according to instructions from an operator.
The document data (code data) inputted from a is stored on the optical disk 19, or is stored on the optical disk 19 of an information processing device (not shown) via the LAN. Furthermore, the title (keyword) of the document that the operator inputs from the keyboard 23 is registered in the database section 52 . This document title is used when searching document data.

The deletion unit 313 deletes the document title stored in the database unit 52 according to the document to be deleted as instructed by the operator.

The modification unit 314 selects document data to be modified according to an operator's instruction, and modifies the document title stored in the database 52.

Selection of document data in the deletion section 313 and the modification section 314 is performed by the search section 311.

The maintenance section 315 performs initialization processing of the optical disc 19 and the like.

Next, a case where the search process is selected by the operator will be described with reference to a flowchart as shown in FIG.

When control is transferred to the search unit 311, the search unit 311
The CRT display 24 says “Which optical disk drive?”
:'' is displayed, and the operator is asked which document data in the optical disk 19 set in which optical disk drive is to be searched. When the operator inputs the optical disk drive number, the search section 311 accesses the optical disk 19 and the database section 52, reads out the binder names defined in the optical disk 19, and displays a list of binder names on the CRT display 24. At the same time, the message ``Which binder?:'' is displayed.

When the operator specifies a binder number using the keyboard 23 or mouse 29, the search section 311 obtains the document title structure of this binder from the database section 52, and displays it on the CRT display 24 as shown in FIG.
Display search window RW. This search window RW displays a search condition input table for inputting search conditions.

The operator enters search conditions into this table and instructs to start the search. The initial value of the search condition input table is all "*", and the total number of documents in the current binder is displayed at the bottom of the search condition input table.
"Number of applicable items" is displayed. In this example, "number of matching cases=IO".

For example, the operator may enter "〉-19670401J" as the "search condition" in the "key name" section of "date of birth".
If you enter the title search and start the search,
Based on this condition, the database unit 52 is requested to perform a search process, and the database unit 52 requests the r 19B7
The number of document data related to people born on or after "April 1, 2017" is searched and displayed in the "Number of matching cases" section.

In addition to the search window RW in which the search condition input table shown in FIG. 5 is displayed, the CRT display 24 displays a document display window DW shown in FIG. The document data created will be displayed. Display of this document data is performed by the document data display section 53, and by instructing "document display" in the search window RW with the mouse 29, the corresponding document data currently being searched is displayed in the document display window DW. can be done.

Furthermore, display attribute information for each member in a document managed within the database section 52 can also be utilized as a search key. That is, it is also possible to search based on elements related to the display format of the document, for example, specifying "Document 10 whose last page is registered as an A3 landscape image."

For such a search, inputs based on the document to be searched can be made in the image size, image direction, rotation angle, and page position fields in the search condition input table. in this case,
A search is performed by instructing a display attribute search and a search start.

FIG. 5 shows that as a result of a search for a document whose image size is A4, whose image direction is landscape, and whose rotation angle is 0 as the last page, there are 10 matching documents.

When “document display” is instructed by the operator, the search unit 311 obtains the start address and data length of the corresponding document data in the optical disk 19 from the result of requesting the database unit 52 to perform the search process, and displays the document. Data input/output section 5
5, the document data is inputted from the optical disk 19 and stored in the page memory 14. The document data stored in the page memory 14 is managed by a document data management section 54 shown in FIG. That is, document data stored in the page memory 14 is attached with a page memory index (hereinafter referred to as PMID), and is identified by this PMID.

The search unit 311 passes the PMID to the document data display unit 53 to display the document data in the document display window DW. That is, the document data display section 53 searches the page memory 14 for document data corresponding to the PMID, and transfers this document data to the display memory 15. The document data stored in the display memory 15 is displayed on the CRT display 24.

At this time, since the data written in the page memory 14 reflects the display attribute information of the page already obtained by the database unit 52, the data individually displayed on the CRT display 24 also reflects the display attribute information of the page already obtained by the database unit 52. Reflects display attribute information.

At the bottom of the document display window DW shown in FIG. 6, a plurality of menus such as "next document" and "previous document" are displayed, and by specifying these menus, the following processes are executed.

"Next document" displays the document next to the currently displayed document from among the retrieved documents. Document data display section 5
3, when "next document" is specified, requests the search unit 311 to input the next document, and then inputs the PMID of the next document.
is received, and the document data in the page memory 14 is displayed in the document display window DW using this PMID.

Upon receiving the manual request for the next document, the search unit 311 obtains the start address and data length on the optical disk 19 of the document data corresponding to the next document, and converts these parameters into the document data in the same way as in the document display process. It is passed to the input/output section 55. The document data input/output unit 55 reads document data from the optical disc 19 and stores it in the page memory 14 managed by the document data management unit 54, and also reads the PMID attached to the document data stored in the page memory 14.
and passes this PMID to the document data display section 53.

"Previous document J displays the document that precedes the currently displayed document from among the documents retrieved from the optical disc 19. The flow of control is the same as the rth document."

Enlarge; Reduce; Rotate; Up: Down; Right; Left: Displays the currently displayed document data by relatively enlarging, reducing, rotating, or scrolling it up, down, left, or right by a certain amount.

When these instructions are given, the document data display unit 53 executes image conversion processing such as enlargement and reduction when transferring the document data in the page memory 14 indicated by the PMID onto the display memory 15. That is, the database section 5
Here, a conversion of a display form different from the display attribute information of the page obtained from Step 2 is performed.

Further, the filing processing unit 51 transmits display attribute information stored in the database unit 52 to the document data display unit 53, the document data management unit 54, the document data input/output unit 55, and the code Image converter 5
A means of inquiry, such as a function, is provided to be passed to 6.

For example, by using this function, the document data display section 53 can inquire about and refer to display attribute information stored in the database section 52 as a default attribute value.

As a result, even when searching for a document in which display attribute information such as different image sizes and image orientations for each page are registered on the optical disk 19 and displaying each page with a unified image size and orientation, it is possible to actually display multiple pages. Before displaying, it is possible to calculate relatively new attribute information for each page at once based on the values in the database section 52, and the operator can display multiple pages in a document as in the past. There is no need to actually check the displayed attribute information with your eyes and then change it.

Next, the case where the document registration process is selected by the operator will be described with reference to the flowchart shown in FIG.

When document registration processing is designated by the operator, the registration unit 3
Control is transferred to 12. First, a registration window consisting of a title registration table (registration condition input table) for inputting the title and search key of the document desired to be registered is displayed as shown in FIG.

The title registration table is similar to the search condition input table as shown in FIG. First, there is a field that displays the name of the cabinet and binder to which it is registered. A title key list is then displayed. The operator can input the title of the document to be registered next to the corresponding title key.

In the lower column of the registration window, there are three function keys: enter the registration page, execute registration, and exit. After inputting the title of the document in the title registration table, the operator presses the function key ``Enter Registration Page''. Then, the registration unit 312 reads the data of the first page of the document to be registered from the scanner 20, for example, if the data is image data, and reads the data from the CRT.
It is displayed on the display 24 to give instructions to the operator. Then, the operator places the first page of the document to be registered on the scanner 20.

Next, the document data input/output unit 55 writes the read data of the first page onto the page memory 14. This data is managed by the document data management unit 54 (PMID). At this time, the document data input/output unit 55 obtains information about the input settings of the input device when the data was input, in this case the scanner 20. Then, data is written into the page memory 14 based on the set value.

This input display attribute information is managed by the document data management section 54. The document data display section 53 displays the data stored in the page memory 14 in the display memory 15.
and display it in the document display window DW.

The operator confirms the first page of the displayed document to be registered on the CRT display 24. At this time, if the user wants to change the display attribute information of that page, he or she presses the function key for changing attributes in the column at the bottom of the window. The subsequent display procedure is the same as that for the search.

When registering a document, the operator presses a function key labeled Execute Registration. Then, the data on the display memory 15 is first copied onto the page memory 14. At this time, the display attribute information of the data is displayed in the document data display section 53.
from there to the document data management section 54. Then, the registration unit 312 transfers the display attribute information and document title value of the data from the document data management unit 54 to the database unit 52.

On the other hand, the database unit 52 passes the logical address on the optical disk 19 where the image data is to be stored to the registration unit 312. Then, the document data management section 54 writes data to the thus obtained location on the optical disk 19. In the same manner, documents from the second page onwards are registered. The registration process ends when the data of the last page is written to the optical disc 19.

Next, the management state of display attribute information for each member in the relevant document in the database unit 52 will be explained. The database unit 52 stores physical data such as addresses and sizes of actual data on the optical disk 19, titles of registered documents, and page images of each member of the documents stored on the optical disk 19. It manages page display attribute information such as size, orientation, and rotation angle. The format of search/display data (management information) for each document in the database unit 52 is configured as shown in FIG.

In other words, the search/display data is as shown in Figure 9.
It is composed of three data sections: a physical data section 71, a title data section 72, and a display attribute data section 73. First, the physical data section 71 contains the storage address of the document data on the optical disk 19, the data size, the data density, the code/image data identification flag, in the case of image data, the data compression method identification flag, and the registration date of the data. Contains information such as the date. These pieces of information are necessary when the filing processing unit 51 accesses the document data on the optical disk 19 at the time of registration and search.

The title data section 72 stores information regarding the title of the registered document written by the registration section 312 at the time of registration. The search unit 311 uses this information when searching for documents. The display attribute data section 73 stores display attribute information of each member in the document. Display attribute data section 73
The display attribute data block within is roughly divided into two elements: display attribute information and attribute setting page range. First, as display attribute information, the image size, image direction,
Information regarding the rotation angle can be set.

The number of pages in which the set display attribute information continues is registered in the attribute setting page range item. For example, if display attribute information such as a rotation angle of 0 degrees for A4 portrait paper is displayed on 5 consecutive pages, 5 is registered in the attribute setting page range item. Furthermore, the display attribute data section 83 manages the total number of data blocks within the document.

As mentioned above, in addition to document title information, display attribute information for multiple pages within a document is managed in a database and can be referenced, so candidate documents can be narrowed down effectively and document images searched efficiently. be able to. Moreover, when displaying multiple pages in a candidate document, by reflecting the display attribute information managed by the database unit 52, the visual effect during search can be improved, and the target document image information can be displayed. It becomes possible to search efficiently.

Note that this invention is not limited to the embodiments described above. For example, the display attribute information managed by the database unit 52 is not limited to image size, image direction, and rotation angle. For example, the following embodiments may also be considered.

That is, consider specifying only a portion of data for multiple pages out of the document data stored in the optical disk 19 and transferring it to the page memory 14 during a document search.

In this case, the database section 52 contains, as display attribute information, the storage position within the optical disk 19 of the data to be transferred from the optical disk 19 to the page memory 14, the data size to be transferred, and the area to be displayed within the page. The coordinate values, the magnification/reduction ratio for displaying the area, and the rotation angle value for displaying the area will be managed. At this time, the search unit 311 searches the optical disk 19 of the corresponding document based on the result of requesting the database unit 52 for search processing in advance.
determines the start address and data length of the file, passes this information and information regarding the display attribute information to the document data input/output unit 55, and inputs the requested data from the optical disc 19;
Stored in the page memory 14, that is, the database section 5
The display attribute information stored in 2 is expanded in a manner that reflects the display attribute information. The operation example for subsequent searches is the same as described above.

With this method, even if you input various image sizes and orientations when registering a document, it is possible to check only the area you want to compare on each page while displaying it with a uniform thickness when searching, and document search The processing time is dramatically improved. Furthermore, after the search is completed, the document data display section 53
By changing the display attributes, it is possible to display an entire page in the document, and the conventional search method can also be maintained.

Furthermore, the storage management position of the display attribute information within the database unit 52 is not particularly limited. For example, the database section 5
What is necessary is to predetermine in which address position the display attribute information is managed with respect to No. 2.

Furthermore, a magnetic disk 27 on which a database section 52 exists
Since a is rewritable, it is also possible to change the display attributes of multiple pages within the document data registered on the optical disk 19 on the database section 52 at a later date, increasing the flexibility of search operations. Improvements are also being made.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to perform not only a search based on search information, but also a search based on attribute information such as image setting direction and rotation angle, thereby improving search efficiency. It is possible to provide an image storage device and an image retrieval device that can perform the following functions.
