“Optical disk”, which is a “character”, is stored as the keyword.

The record number of the page management table 26b corresponds to the record number of the title management table 26a.

FIG. 4 shows the record management table 26c. The record management table stores the storage address, image length, image attribute, and search frequency of each record.

Next, the operation of image storage and retrieval processing in the electronic filing apparatus having such a configuration will be described.

First, the image storage process will be described with reference to the flowchart shown in FIG. For example, the registration mode is now selected and set by the keyboard 23. Next, the title of the document and the part to be used as the search keyword are previously surrounded with a rectangular frame or a circular frame with a pencil or the like. That is, the title candidates in the document are enclosed in a large frame with a pencil (step 501), and the keyword candidates in the document are enclosed in a small frame with a pencil (step 502). Then, the original is set on the scanner device 18, and the CPU 34 causes the optical disk device 20 to operate.
And the scanner device 18 is operated. Scanner device 1
Reference numeral 8 two-dimensionally scans an image of a set document or the like (step 503) and photoelectrically converts the image. The line information of the photoelectrically converted image is sequentially stored in the page memory 40 (step 504). The image stored in the page memory 40 is stored in the display memory 42, and the display control unit 44
Displays the stored contents of the display memory 42 on the CRT display device 24.

Next, the image stored in the page memory 40 is transferred to the character recognition unit 39 (step 505), where projection, which is a preprocessing of the character recognition processing, is performed, and the frame in the image is extracted. (Step 506).

Generally, when detecting and cutting out characters,
By utilizing the projection of the figure on the x-axis and the y-axis as shown in FIG. 6, the character-by-character separation is performed. About this projection (Nakada, Nakano, Uchikura: Recognition of Chnese Characte
rs, Proc.of the Conference onmachine perception of
patterns and pictures held at the NPL, Teddington,
(1972, April)).

FIG. 7 shows the projection when a character is surrounded by a frame. When the character is surrounded by a frame in this way, the projection of the frame part projects from the character part, so the frame part and the character part are projected. Can be distinguished. Therefore, the frame can be extracted.

The present system recognizes the characters in this frame, makes them candidates for titles and keywords, and displays them on the CRT display device 24 as shown in FIG. The operator will select a title and a keyword by picking from these title and keyword candidates with a mouse or the like.

In this case, when the inside of the frame is a chart, it is not known what the recognition result will be, so that the recognition result within the frame is to be selected by the operator.

The character recognition unit 39 determines whether the title or the keyword is a candidate based on the size of the frame (step 507).
Display device 2 with the largest frame as a title candidate
No. 4 is displayed on the display device 24 as a keyword candidate (step 508).

For example, the display device 24 is shown in FIG.
Is displayed. The read document 801 is displayed on the left half of the screen, and the character-recognized title candidates (here, "1. UNIX 1.2.3") are displayed on the upper right part of the screen.
802 is displayed, and search keyword candidates (here, “OS”, “multitask”, “UNIX”,
...) 803 is displayed.

The operator picks a desired candidate from the title candidate and the keyword candidate displayed on the display device 24 with the mouse 29 to select it (step 509). Then, the character code corresponding to the title and the keyword is selected and temporarily stored in the main memory 38 (step 510). At this time, if the character-recognized title candidate or keyword candidate is erroneously recognized,
It can be corrected with keywords. When the title candidate and the keyword candidate are satisfactory, a memory key (not shown) is input.

The CPU 34 puts "00" in the frame of the image on the page memory 40 corresponding to the frame extracted by the projection.
The frame is erased by writing "H" (white) data (step 511). The framed image on the page memory 40 is compressed by the CODEC 50 and then stored in the optical disc 19 (step 512).

That is, the CPU 34 uses the page memory 40.
In the compression / expansion circuit (CODEC) 50 for each line information, the image stored in
The encoding process is performed by band compression by the iedRead method or the like. The encoded image is supplied to the optical disc device 20 and stored in the optical disc 19.

When the storage of the image on the optical disk 19 is completed, the CPU 34 uses the physical track address where the image is stored, the logical address determined from the physical selector address, the image length represented by the block length, the image attribute, etc. as the retrieval code. Corresponding and stored in the main memory 38. Next, the CPU 34 supplies the search data (title, keyword) stored in the main memory 38 to the magnetic disk device 27. As a result, the magnetic disk device 27 stores the supplied search data in the title management table 26a, page management table 26b, and record management table 26c in the magnetic disk 26 (steps 513 and 51).
4).

Next, the search processing of the image stored in the optical disk 19 will be described. First, the search mode is set by the keyboard 23, and the search keyword corresponding to the image to be searched is input. The CPU 34 sequentially compares and collates the input search keyword with the search keyword stored in the page management table 26b of the magnetic disk 26, and sequentially checks whether or not the search keyword that matches the input search keyword is stored. Then, the corresponding record number is extracted. As a result, the CPU3
4 is the record number of the extracted candidate in the main memory 38
Remember.

Then, the CPU 34 refers to the record numbers of the candidates in the main memory 38, creates a list of relevant documents with the data read from the title management table 26a, and displays it using the CPU display device 24. With this display, if the document for which the operator is desired to be searched cannot be found, the search keyword is input again. If found, specify the image to be searched from the list (specified by document number etc.) and specify the search execution.

The CPU 34 reads the logical address corresponding to the record number corresponding to the designated image from the record management table 26c in the magnetic disk 26, calculates the physical track address and the physical selector address corresponding to this address, The optical disk device 20 reproduces the image including the search keyword from the optical disk 19 by using these addresses.

The CPU 34 also supplies the image (compression information) for each scanning line supplied from the optical disk device 20 to the compression / expansion circuit 50, performs band expansion processing, and sequentially supplies the page memory 40. The image stored in the page memory 40 is reduced by the enlargement / reduction circuit 46 and output to the display memory 42, and the image is stored in the display memory 42. Therefore, the display control unit 44 controls the display memory 4
The stored contents of No. 2 are displayed on the CRT display device 24.

As described above, according to the above-described embodiment, the frame in the document is extracted by the projection which is the preprocessing of the character recognition process, and the character recognition result in the largest frame is used as the title candidate and the others. The character recognition result in the frame is displayed as a search keyword candidate on the CRT display device, and by designating with the mouse from among those candidates, it becomes a title or keyword, so scanning of the input key is not necessary and registration is performed. The processing can be simplified.

Therefore, the title and the portion to be used as the search keyword in the document are surrounded by a frame in advance, the frame is extracted by the projection which is the preprocessing of the character recognition process, and the character recognition result in the frame is used as the title candidate and the search keyword. CR as a candidate
By displaying it on the T display device and designating it with the mouse from the candidates, it becomes a title or a keyword, so that the operation of the input key is not necessary and the registration process can be simplified.
