Abstract

PURPOSE: To easily apply an index as a graphic document name by entering index information on index paper at the time of generating a document and then allowing a processor to read out the document including the index paper. CONSTITUTION: The initial document record of a retrieved result is extracted, and when a character code document name exists in the document, the character code document name is displayed. After plotting the preparation date of the document and the total number of pages included in the document, whether the document code is the final result of the retrieval result or not is inspected. When the document code is the final result, the display processing of a retrieved result list is ended. Since a document of which character recognition/conversion from a graphic character name does not succeed does not include a character code document name, a graphic document name is displayed. When the character recognition/conversion of a document succeeds, a character code document name is displayed without displaying its graphic document name.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image information processing apparatus such as an electronic file.

[0002]

2. Description of the Related Art Conventionally, document information called an electronic file or the like is converted into electric information by a photoelectric conversion element such as CCD, and the electric information is stored in a storage medium such as an optical disk.
Later, there is a document image information processing apparatus that retrieves information in the storage medium and displays it on a display or outputs it to a printer or the like.

In such a device, when a document is read, a keyword such as a document name is usually used as an index by an operator through a keyboard or the like attached to the device, and is used as a means for later retrieval. Is configured.

[0004]

As described above, in the conventional document image information processing apparatus, the operator needs to input a keyword such as a document name from the keyboard when reading the document. First of all, an operator who is not familiar with a keyboard is forced to perform a difficult task every time one document is read.

Further, the conventional document image information processing apparatus also has the following problems.

The time when the document is generated, that is, the time when the user creates the document or the time when the received document is read is usually the time when the most appropriate document name can be recalled. It is not always possible to have a device read a document.

That is, when the device is installed at a remote place, when another user is using the device, or when there is not enough time to perform the reading operation at such a time. Is. In such a case, the device will be read at a point some time after the document was generated.

Therefore, as described above, the input of the document name from the keyboard or the like is at the time when the document is read into the device. Therefore, in the case where the document is read after the document is generated as described above, It is difficult to give an optimal document name to the document. And in some cases again only for the purpose of thinking about the document name,
It will be necessary to reread the document.

In view of such circumstances, the applicant of the present application has proposed a method in which a document read by an information processing apparatus includes a mark sheet having index information of this document (Japanese Patent Application No. 2000-242242). Flat 5-325,99
No. 2, filed on November 30, 1993).

According to this method, image information written in a predetermined area in the read mark sheet is extracted and used as a graphic document name. The graphic document name is entered by using a keyboard when registering the document. Even without doing so, the document can be identified on the search list.

However, the operability cannot be said to be sufficient, for example, a search result list of only graphic document names is displayed.

Therefore, an object of the present invention is to provide a document image information processing apparatus capable of ensuring efficient search work in displaying search results.

Further, according to the present invention, in displaying the search result,
An object of the present invention is to provide a document image information processing device that can eliminate useless display areas.

[0014]

According to the present invention, the document image information read by the image reading means is stored in a storage medium, desired document image information is searched from the storage medium, and the plurality of searched image information are searched. In a document image information processing apparatus for displaying a list on a display unit, an input unit for inputting a first index for identifying document image information,
Extracting means for extracting a second index for identifying the document image information from the image information read by the reading means; and converting the second index,
When this conversion process is successful, the conversion means for inputting the conversion result as the first index, and the first index input by the input means or the second index extracted by the extraction means are stored. Storing means, a searching means for searching the document image information stored in the storage medium according to a predetermined search condition, and a first index corresponding to each of the plurality of document image information searched by the searching means. If it is stored in the storage means, the first index is displayed on the display means as a search result list, and the second index corresponding to each of the plurality of retrieved document image information is stored in the storage means. Then, it has a control means for displaying the second index on the display means as a search result list. .

With the above-mentioned structure, it is possible to display two types of indexes in a mixed state in the search result display, and it is possible to perform an efficient search operation.

Further, according to the present invention, the document image information read by the image reading means is stored in a storage medium, desired document image information is searched from the storage medium, and a list of a plurality of searched image information is displayed. In the document image information processing apparatus to be displayed on, the input means for inputting the document name of the document image information to be stored in the storage medium as code information, and writing in the specific area of the specific sheet read by the storage means together with the document image information. Extraction means for extracting the extracted image information, storage means for storing the document name input by the input means or the image information extracted by the extraction means in association with the document image information, and the document image information code Converting to information, if the conversion process is successful, the conversion means for inputting the conversion result as the document name, and a predetermined search information. When the searching means for searching the document image information according to the above and the document name corresponding to the document image information searched by the searching means are stored in the storage means, the document is included in the list of the searched document image information. When the name is displayed on the display means and the document name corresponding to the retrieved document image information is not stored in the storage means and the corresponding image information is stored, the retrieved document image And a control means for displaying the image information by inserting it in the information list instead of the document name.

With the above configuration, in the search result display, only one of the two types of indexes is displayed for one document, and a useless display area due to blank display, duplicate display, etc. can be eliminated. .

[0018]

FIG. 6 is a perspective view showing the external appearance of an image information processing apparatus according to an embodiment of the present invention, and FIG. 7 is a perspective view showing the internal structure of the image information processing apparatus. Also, FIG.
FIG. 3 is a block diagram showing a configuration of a control circuit of the image information processing device.

In FIG. 6, a document 1 is placed on a document table 2 and is sandwiched by control plates 3a and 3b which regulate the conveyance of the document. Further, a paper discharge unit 4 is provided on the upper portion of the image information processing apparatus, and a screen 5 for displaying image information or operation instructions is provided on the front surface. Further, on the side surface, an insertion opening 6 for inserting the magneto-optical disk 35 which is a storage means is formed.

Next, registration of the image index, which is the first index, will be described.

First, prior to the storage of the actual document image, a symbol image (referred to as an image index) related to the document to be stored in the future is stored in the magneto-optical disk 35 in advance.

This operation is carried out in the same manner as the storage of the original image described later, and FIG.
As shown in FIG. 9, for example, the index key including the character image of “part” in FIG. 9 is designated to be displayed at the upper left using the function key 34.

Here, although the function keys are arranged in a row in the horizontal direction in FIG. 9, for example, by pressing the leftmost function key (the one with the letter "1") twice, The second position from the top can be designated.

When a plurality of image indexes are stored in this way, an index image data file is created on the magneto-optical disk 35 as shown in FIG.

Here, the date and time when the index image data file is generated will be referred to as an image index date. The image index date is encoded and written in a specific area on the magneto-optical disc 35.

Further, it is not the case where a new index image data file is generated, but a certain index image is changed, erased, and the index image is moved, that is, the image indexes of, for example, a and b are exchanged in FIG. Also in this case, the image index date on the magneto-optical disk 35 is updated.

The above-mentioned control is performed by the CPU 10 and the CPU 1.
This is executed by the ROM 11 in which an instruction for causing 0 to perform the above-mentioned control is written.

Next, the creation of the document name registration sheet will be described.

The document name registration sheet is generated by the CPU 10 that performs the control described below, and the ROM 1 in which an instruction for causing the CPU 10 to perform the control described below is written.
This is performed by the index paper generating means consisting of 1.

FIG. 2 is a plan view showing the document name registration sheet.

As will be described later, the reference marks 201a and 201b are marks for detecting the positional deviation such as skewing that occurs when the document registration sheet is read, and the bar code 202 is described later. When the document registration sheet is read, the sheet identification code is used to determine that the read sheet is the document name registration sheet.

Here, a disk ID for specifying the magneto-optical disk is written in a specific area on the magneto-optical disk 35, and from the magneto-optical disk 35 loaded at the time of creating the document name registration sheet, The barcode 2 is the one that is read out from this disc ID and drawn in the bar pattern.
It is 06.

The image index date read from the magneto-optical disk 35 loaded at the time of creating the document name registration sheet is also drawn as a bar code 207.

In the image index mark column 208, the image index written on the optical disc 35 loaded at that time is drawn, and the mark frame 209 is drawn at the position where the image index exists.

When the operator operates the function key 34 to instruct the CPU 10 as the control means to create a document name registration sheet, the CPU 10 causes the graphic RAM 13 to read the above-mentioned information read from the magneto-optical disk 35. Image information based on the graphic RA to the printer 31 such as LBP which is an output means via the output data flow controller 30.
A document name registration sheet is generated by transferring the contents of M13.

Next, the entry on the document name registration sheet will be described.

The document name registration sheet 200, which is an indexing means, is provided in the document name column 203 of the sheet shown in FIG. 2 created by the image information processing apparatus itself, as a means for later retrieving this document. Enter the document name. Further, an X mark is written by the operator in the mark frame 209 attached to the image index to be given to this original.

In the example of FIG. 1, "Experimental Report No. 53"
The document name is written with a felt-tip pen or the like, and a mark is attached to the image index composed of the character images of “report” and “experiment”.

Next, the operation of document storage will be described.

When storing a document, the document 1 is stacked on the document table 2 as shown in FIG. 6, and when the operator gives a storage operation instruction with the function key 34, the document is started to be conveyed.

Here, at the top of the manuscript 1, the document name registration sheet 20 which is the index means shown in FIG.
0 is loaded.

When the storage operation is started, the feed roller 102 first rotates in the direction of the arrow to feed the document to the separation section. The separation unit is composed of a paper feed roller 103 and a separation roller 104, each of which rotates in a counterclockwise direction. The surface layer of the original document (uppermost original document) is fed first. It is left by the gap between 103 and the separation roller 104 and the frictional force between the separation roller 104.

The original 1 sent first is next conveyed by the conveyance roller 1.
The reading unit is reached by 05. Here, the image information of the document illuminated by the illumination lamp 106 is displayed on the mirrors 107-
After passing through 109, it is reduced to a lens 110 and read by a CCD 111 which is a reading means. The apparatus of this embodiment has a configuration capable of reading both sides simultaneously.

Then, the read originals are stacked on the discharge tray 113 by the discharge rollers 112.

The above process is continuously performed, and the document table 10
When the document sensor 120 detects that there is no document in No. 1, the process ends.

The drive system 19 is composed of the above-described original document sensor 120 and a motor (not shown), and the above-described conveyance is performed by the CPU 10 controlling the drive system 19 via the drive system interface 18.

Front surface CCD 111a and rear surface CCD
The image signal obtained by 111b is the amplifier 20a,
It is sent to the synthesizing unit 36 through 20b.

After passing the data for one line of main scanning from the front CCD 111a to the next stage, the synthesizing unit 36 switches the internal switching element, and then the image data for one line of main scanning from the back CCD 111b is passed to the next stage. It has a function to pass to.

In this way, the front and back image data are serialized in units of one line for main scanning and sent to the compression unit in the next stage.

The above is the description of the double-sided reading. However, when the single-sided reading is instructed to the synthesizing section 36 by the instruction of the CPU 10, the above switching is not performed and the image from the front surface CCD 111a is always displayed. The data will be sent to the next stage.

The image signal from the synthesizing section 36 is quantized by the A / D converting section 21, and then image processing such as edge enhancement is applied by the image processing section 22 and the binarizing circuit 23 reduces the image signal to 1/0. Converted to data.

The subsequent operation will be described with reference to the flow charts shown in FIGS.

One of the binary image data is stored in the graphic RAM 13 (step 1), the other is MH,
Well-known image information compression such as MR and MMR is performed by the compression unit 24 and then stored in the compressed data buffer 33a or 33b.

The graphic RAM 13 is constructed so that the output data flow controller 30 draws the stored data on the display 32 which is a display means, and is stored on the graphic RAM 13 as described above. The binary image data is displayed on the display 32.

Next, the operation of detecting the document name registration sheet will be described.

The detecting means for detecting that the image information read as described above is the image information of the document name registration sheet, the CPU 10 for performing the control described below, and the control for the CPU 10 described below. It is composed of a ROM 11 in which an instruction for writing is written.

FIG. 1 is an explanatory diagram showing a state in which the filled-in document name registration sheet is stored in the graphic RAM 13. As will be described later, this indicates that the document name registration sheet is the result of being conveyed while being inclined by θ.

Here, in the ROM 11, what is read at that time is the document name registration sheet 200 of FIG.
1 is stored, the area of the address on the graphic RAM 13 where the reference mark 201a in FIG. 1 may be written and the width 201a-w and height 201a-h of the reference mark 201a shown in FIG. 1 are stored. Has been done.

Therefore, the CPU 10 reads the above-mentioned address, width and height from the ROM 11 and sends the graphic R
It is inspected whether or not there is a black area having such width and height in the address area on the AM 13 (ste.
p2).

Then, if such a black area is not found, it is processed as a normal document.

If such a black area is detected,
Another detected reference mark 201a, which is supposed to exist near a predetermined coordinate position whose origin is, for example, the center point in the vertical direction at the left end of the rectangle (hereinafter, this point is referred to as a representative point of the reference mark), is set. The detection of the reference mark 201b is started (step 3).

This predetermined coordinate position is the same as that shown in FIG.
It is a position moved in the vertical direction indicated by 201a-b therein, and these coordinates are also stored in the ROM 11.

Here again, if the reference mark 201b is not detected, the document is processed as a normal document.

If detected, the skew angle of this image is obtained from the horizontal shift length of the representative points of the two reference marks 201a and 201b, as shown by θ in FIG. 1 (step 4). ).

Next, the reference mark 201 is stored in the ROM 11.
The coordinates of the central point (not shown) of the bar code 202, which has the representative point of a as the origin, are stored. Therefore, this is read out, the coordinates are rotated by the above-mentioned θ, and then stored in the ROM 11 as well. The point BP moved to the left by ½ of the horizontal length of the bar code 202 is set as the decoding start point of the bar code 202.

Next, the bar code 202 is decoded for the lines on the graphic RAM 13 shown from BP to BL in FIG. 1 (step 5).

Here, if the decoding of the bar code 202 is not normally completed, it is processed as a normal original (step 6).

When the decoding is normally completed,
The decoding result is collated with the sheet identification code stored in the ROM 11, and the CPU 10 recognizes that this sheet is a document name registration sheet.

Next, the analysis operation of the document name registration sheet will be described.

First, the bar codes 206 and 207 are
Decoding is performed in the same manner as the barcode 202. If the disc ID and index date on the magneto-optical disc 35 described above do not match the results of decoding the barcodes 206 and 207, an error occurs and the reading operation is stopped (step 7).

If they coincide with each other, then the inspection of the image index mark column 208 is started. This is a method similar to that described above, in which the relative coordinates of each mark frame stored in the ROM 11 from the reference mark 201a or 201b are rotationally moved by θ to calculate the position of each mark frame, The number of black pixels in the frame is counted, and if the count result is equal to or greater than a certain value, it is determined that the mark frame has a mark such as x.

In the example of FIG. 1, it is recognized that a mark exists in the image indexes of c and h, and as shown in FIG.
An image index pattern in which the bit position corresponding to the marked index image is "1" is generated (step 8).

Next, the operation of extracting the graphic document name will be described.

Next, the image in the document name column is extracted. This extracting operation is composed of the CPU 10 for performing the control described below and the ROM 11 in which the instruction for causing the CPU 10 to perform the control described below is written. It is done by extraction means.

In this embodiment, the coordinates of the upper left point of the document name column with the reference mark 201b as the origin are read from the ROM 11, and the coordinates are rotated by θ as described above.
The coordinates of the upper left point IP in the document name column are calculated.

Next, the image in the document name column is cut out, and at this time, the skew correction of this sheet is performed on the image information in the document name column. That is, as shown in FIG. 3, by copying pixels in the vertical direction every time the pixel corresponding to θ in the horizontal direction is advanced, a rectangular area where all the written document names are horizontal, that is, 205 in FIG. The image operation is performed so that the image is stored in the document name field area shown in (step 9).

Next, the image in the document name area 205 on the graphic RAM 13 is displayed on the disk interface 27.
The data is sent to the magneto-optical disk drive 115 via the and is written as a graphic document name on the magneto-optical disk (step 10). This processing is performed by the CPU 10 and the CP.
RO in which an instruction for performing the above-mentioned processing is written in U10
It is made by a writing means composed of M11.

Here, the ROM 11 stores a known program for character recognition. That is, ROM1
The conversion unit composed of 1 and the CPU 10 attempts to convert the image data of the document name area 205 on the graphic RAM 13 into character code data (step 11).

In this character recognition, if the certainty of the character conversion is less than a certain value, it is judged that the conversion is impossible (step 12). Therefore, if the conversion is not possible, nothing is done, but if the conversion is successful, the conversion result is written in the magneto-optical disk as the character code document name (step 13).

If the CPU 10 analyzes the graphic RAM 13 and determines that the sheet is not a document name registration sheet, the compressed image data stored in the compressed data buffer 33a or 33b is transferred to the magneto-optical disk drive via the disk interface 27. 115
Is sent to the magneto-optical disk as an image of a document, and the written position on the magneto-optical disk 35 is stored in the page management file described later in the nod described later.
It is stored as e.

Here, the compressed data buffers 33a and 33a
Two of b are provided, for example, while the compressed image data in the compressed data buffer 33a is being written on the magneto-optical disk, the next original is scanned and the compressed data is stored in the compressed data buffer 33b. This is because.

As a result, the restriction that the scanning of the next original must be waited for until the writing of the image data of the previous original on the magneto-optical disk is completed is avoided, and the storage speed of the original is improved.

The graphic document name is written as a third index on the magneto-optical disk 35, and subsequently, the above-mentioned document storing operation is performed, and when the document storing is completed, the magneto-optical disk 35 is completed. A record of the document stored at that time is generated in the document management file shown in FIG. 12 above. Here, in the column of the graphic document name node, the storage location of the image data of the graphic document name on the magneto-optical disk 35 is written as a node described later.

When the code conversion by the character recognition is successful, both the node of the graphic document name and the character code document name are stored as in the record indicated by k in FIG. If the code conversion fails,
Like the record indicated by j in 2, only the node of the graphic document name is stored.

Here, without using the document name registration sheet, it is also possible to input the document name by the character code from the keyboard 200 prior to the storing operation.

Therefore, in the document file, for each document, the nod of the image data of the graphic document name is given.
Either e or the document name by the character code is included.

In the document management file of FIG. 12, a document in which the item of node of the image data of the graphic document name is 0 means that the document is not given a graphic document name. .

Further, as shown in FIG. 5, a plurality of documents including the document name registration sheet on each head page are collectively loaded on the original platen 2 and the plurality of documents are read in a batch. Is also possible. That is, since the document name registration sheet detection operation described above is performed for all originals, when a second document name registration sheet shown in FIG. Since it is generated as a file, the first document, the second document, the third document,
As shown in the fourth document, the document is divided by the document name registration sheet.

Next, the node and FAT will be described.

In this embodiment, the position of the image data on the magneto-optical disk on the disk is no as shown in FIG.
The data table called the de table is used as the magneto-optical disk 3
5 is managed by holding on.

Next, the FAT entry in FIG. 14 will be described. FIG. 15 shows a storage area inside the medium of the magneto-optical disk 35. Such a disc is divided into areas by physical divisions called tracks and sectors as shown in FIG. Hereinafter, this physical division will be referred to as a physical address.

In the magneto-optical disk drive 115, an area for storing or reading information is designated from outside the drive by these physical addresses.
Normally, inside the CPU unit, which is the control unit, is managed by a logical area division known as a known cluster. Hereinafter, the position information of this logical area division is referred to as a logical address.

The correspondence between the logical address and the physical address is
Inside such a system, as shown in FIG. 16, it is uniquely determined, and determining a logical address is equivalent to determining a physical address.

Here, on a fixed physical address on the medium, a list of unused / in use / erasure of the area designated by this logical address is stored.

In this example, FFFF is used when the cluster is unused and FFFE is used when the cluster is in the erased state.
, And 0000 when the cluster is the last cluster of the file, and further, when the cluster has a continuing cluster, the logical address of the continuing cluster is written.

The difference between erase and unused is as follows.
Unused is a state in which there is no meaningful information at the destination pointed to by the logical address, and erasing is a state that appears after a file erase operation, and the destination pointed to by the logical address is The information still exists.

The above-mentioned cluster management is normally performed by FAT.
It is performed by a table called (File Allocation Table). FIG. 17 shows this FAT.

The upper row of FIG. 17 shows the logical address, and the lower row shows whether the logical address is unused or in use.

FIG. 18 shows logical addresses 62B0 to 62B.
BA has been used and 62BB to have been unused.

Further, 62AD to 62AF indicate that the file was previously a part of a valid file but was later deleted.

The above node table is a FAT that indicates which position of this FAT is the image data.
This is a table in which the entry (62B0 in the above example) and the size (byte number) of the compressed image data are one record, and the number of the record in this node table is called “node”, and will be described later. This is described for each page of the original in the field of the node of the page management file or for each document in the field of the graphic document name node of FIG.

Next, the document management file and page management file will be described.

Here, in the document management file, the creation date and time (storage date and time), the total number of pages, etc. obtained from the timing unit 15 in FIG. 8 are also recorded.

Information about each page of the stored document is written in the page management file of FIG.

The "page file pointer" in the document management file means which record in the page management file is related to the first page of the document which is timed at that time.

The record for this page also stores the front / back mode, that is, whether the page was read on both sides or one side, as described above.

As described above, in the document storing operation, the image data of the graphic document name and the compressed image data are written on the magneto-optical disk 35, and the records are recorded in the node table, the page management file and the document management file, respectively. It ends by being added.

Next, the operation for searching and displaying the stored image will be described.

The search operation described below is performed by the CPU
This is performed by the document image information retrieving means including a ROM 11 in which instructions are written so that the CPU 10 and the CPU 10 perform the following control.

First, at the time of retrieval, the display of FIG. 10 is displayed on the display 32, and the operator selects the function key 3
Use 4 to select the image index.

The CPU 10 generates an image index pattern on the RAM 12 as shown in FIG. 11, depending on which image index is selected.

Next, the CPU 10 checks the document management file record by record and selects a record having an image index pattern that matches the index pattern on the RAM 12 described above.

Here, the selected image index is
For example, in the case of only the image index of c including the character image of “experiment” in FIG. 10, the image index including the character image of “report” is not selected, and thus the image index pattern is different from that of FIG. 11. Unlike, the bit corresponding to h is 0.

However, when the record of the document management file in FIG. 12 is examined, the image index in which "1" is set at the same bit position as "1" is set in the image index pattern selected at the time of search. It is configured to select all records that have a pattern.

Next, the display of the search result list will be described.

This display operation is performed by the graphic RAM 13
/ Output data flow controller 30 / Display 32
/ And CPU10 / and CPU1 for controlling them
The display means is composed of the ROM 11 in which an instruction is written so that the following control is performed by 0.

The CPU 10 executes the first operation for the record of the document management file of FIG. 12 selected as described above.
It is checked whether there is a document name by the character code that is the index of, or there is a graphic document name that is the second index, and the existing one is displayed as a search result.

By the way, as a method of displaying such a search result, the method shown in FIGS. 25 and 26 can be adopted.

That is, in this method, the display area of the document name and the display area of the graphic document name by the character code input by the keyboard or obtained by recognizing the graphic document name are arranged in parallel, and the file number is set. In a corresponding state, the document name by the character code and the graphic document name can be individually displayed in each display area. Therefore, input from the keyboard,
Alternatively, the search result of the document with the document name by the character code obtained by recognizing the graphic document name and the search result of the document with the graphic document name can be mixed and displayed, so that the desired document can be specified. Easier to do.

However, normally, for one document, the graphic document name or the keyboard is used,
Or only one of the character code document names obtained by conversion from graphic document names is required,
Since only one side is often used, in the display method of FIG. 25, the areas indicated by a, b, and c in the figure are always blank,
It means that the display area is wasted.

Further, when there is a character code document name obtained by recognizing and converting a document to which a graphic document name has been added, as shown in FIG. 26, there is an index having the same meaning. It will be displayed redundantly,
Also in this case, the display area is wasted.

Therefore, a display method capable of eliminating a useless display area when a search result list including a document name by a character code and a graphic document name is displayed will be described.

FIG. 18 shows a display example of the search result list in this embodiment. As shown in the figure, the maximum number of document names are displayed without wasting the display area in a state where the document name based on the character code which is the keyboard input or the conversion result and the graphic document name are mixed. The display operation will be described later.

Further, the CPU 10 determines that the graphic document name exists, that is, the item of node in FIG.
For documents that are not, the graphic document name nod of the record of the document management file selected as described above.
The FAT entry for the image data of the graphic document name is obtained from e through the node table, the image data of each graphic document name is read from the magneto-optical disk 35, written in the graphic RAM 13, and output via the output data flow controller 30. Display 32
Is displayed. The creation date and total number of pages are also displayed. The state of this display is shown in FIG.

When the operator operates the function key 34 to select one of these documents, based on the page file pointer of the record in the document management file, the page management file of FIG. By selecting the record of the first page of the document and specifying the node, the FAT entry of the first page is obtained from the node table.

Therefore, by tracing the FAT of FIG. 17, the logical address sequence is obtained and the disk drive 115
More sequentially compressed image data is the disk interface 2
It is read out via 7.

At this time, also under the control of the CPU 10, the disk data flow controller 26 is in a state of functioning to send the compressed image data from the disk interface 27 to the decompression unit 25.

At this time, the output data flow controller 3
0 indicates that the image data from the decompression unit 25 is a graphic RA.
The image data stored in the M13 and stored in the graphic RAM 13 is displayed on the display 32 in the same manner as when the image is stored.
The CPU 10 gives an instruction to function as displayed above.

In this way, the compressed image data on the magneto-optical disk is displayed.

When obtaining an image print, the CPU 10 sends the image data in the graphic RAM 13 to the output data flow controller 30 in the state where the above-mentioned image is displayed on the display 32.

FIG. 22 is a flow chart showing the operation of displaying the search result list shown in FIG.

First, in S1, the first document record of the search result shown in FIG. 12 is taken out, and in S2, it is checked whether or not the document has a character code document name.
If the character code document name exists, the character code document name is displayed in S3, and the process proceeds to S6. If it does not exist, in S4, it is checked whether or not the graphic document name exists, and if it exists, that is, node
If the item is not 0, the graphic document name is drawn in S5, and the process proceeds to S6.

After the creation date of the document and the total number of pages included in the document are drawn in S6, it is checked in S7 whether the document record is the last document of the search result. If it is not the last one, the next document record is extracted in S8, and S2
Return to If it is the last one, the display processing of the search result list ends.

By such control, the search result list shown in FIG. 18 is displayed.

As shown in FIG. 18, since the character code document name does not exist in the document in which the character recognition / conversion from the graphic document name has not succeeded, the graphic document name is displayed. In addition, for a document whose character recognition / conversion is successful, the graphic document name attached to the document is not displayed but the character code document name is displayed.

Next, index retrofitting will be described.

First, FIG. 19 is an explanatory diagram showing a state in which an image to which a graphic document name has been added by the storage operation described above is searched and displayed by the search operation described above.

Here, when the character recognition / conversion from the graphic document name is not successful, or when an incorrect conversion is performed, the operator inputs the character code index from the keyboard 200. This process is called post-indexing / correction.

That is, the operator inputs the correct character code document name while looking at the graphic document name shown in FIG. 19 and checking the image displayed at the same time.

In the example of FIG. 19, "Experimental Report No. 5"
As a result of erroneously recognizing "3", "Experimental Report No. 58" has been corrected.

FIG. 20 is an explanatory diagram showing the state of the document management file after the character code document name has been input, that is, added / corrected in this way.

FIG. 21 is an explanatory diagram showing the state of the list display after the above-mentioned retrofitting / correction is performed on the document for which the recognition / conversion is not successful and the character code document name is given to all the documents. That is, when both the character code document name and the graphic document name exist, the character code document name is displayed with priority.

Although the method shown in FIG. 18 is adopted as the optimum display method of the search result list in the above embodiments, the display methods shown in FIGS. 25 and 26 are also included in the present invention. This is a display method according to another embodiment of the present invention, and has a sufficient effect in displaying a character code document name and a graphic document name in a mixed manner.

[0145]

As described above, according to the present invention,
By writing the index information on the index sheet at the time of generation of the document and then causing the document image information processing device to read the document including the index sheet, indexing as a graphic document name can be easily performed, Furthermore, if character recognition / change from graphic document name is successful, without key input,
Character code Document name can be entered.

Since the index based on the character code is preferentially displayed, if the character recognition / change succeeds, the result of the change is displayed, and if it fails, the graphic document name is displayed. The display area can be effectively used in displaying the search results.

Further, for documents whose recognition / conversion has failed or documents which have been erroneously recognized, index correction can be performed, and the character code index can be added and corrected by key input while displaying the graphic document name. Yes, after the document name in character code is entered,
Since the unnecessary graphic document name is not displayed, the search results and the like are simple and easy to see, and the number of search result documents that can be displayed on one screen of the display unit is increased.
