Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image information storage method in an image information storage and retrieval device that can store image information such as documents and retrieve and output it as needed.

Traditionally, document images have been stored and searched to their core, but
There is a type of microfilm that records reduced images as is. However, recently, as an alternative to this, photoelectric conversion technology using laser light and CCD elements has been used to decompose document images into pixels and convert them into electrical image signals. Devices that record information on disks using laser light and devices that perform high-density storage on magnetic storage media are being developed.

For example, in the case of the latter type of magnetic storage media, dozens of A4-sized documents can be stored on an endlessly wound magnetic tape with a length of about 36 m, and it is used as a document storage system. It is very convenient. Additionally, the storage location of the document image can also be stored as an index code on the same magnetic tape, and by inputting this index code as needed, the document image corresponding to the index code can be stored. It can be searched and retrieved as a hard copy.

However, when storing, for example, the format of a letter or the personal information of an employee at a company, there is no problem in storing each document with its own index code added each time. book 1
When attempting to memorize pages from page 1 to page 10, an index code associated with the book and a code representing the page must be input for each page, even though the document is a series of documents. Also, when storing patent publications, for example, if the patent number is used as an index code, it is necessary to add a page code to the index code to make it into one index code, so it is necessary to store the Bunsou image as one index code.
It is necessary to input the patent number and page code as an index code each time a page is input. in this way,
Inputting index codes when storing a series of documents is extremely complicated.

The present invention has been made in view of the above-mentioned problem, and its purpose is to store a drawing of an embodiment of the present invention in the index section for each image information on each side when storing a series of image information. Refer to and explain.

1 to 3 show the configuration of an image information storage and retrieval device according to the present invention, in which a control device 1 records image information and index information according to input information from an input device 2 such as a keyboard. , perform editing processing such as playback, addition, insertion, and deletion. The display device 3 is, for example, a CR, T display device, which provides various operational guidance under the control of the control device 1, or visually displays input information and output information as necessary. Actually, it is configured integrally with the input device 2. Image information P1 such as a document is processed by a two-dimensional scanning device (scanner, 5C6
) 4 is optically scanned two-dimensionally and photoelectrically converted, and the photoelectrically converted image information (video signal) is sent to the control device 1
The data is supplied to a recording device (printer, PR, etc.) 5 or a magnetic tape device (LVR) 6 as an image information storage device. The recording device 5 is a printer that selectively receives image information from the two-dimensional scanning device 4 or reproduced image information from the magnetic tape device 6, converts it into a two-dimensional visible image, and outputs it as a hard copy P2.

The input device 2 has a key arrangement as shown in FIG. 2, for example.

FIG. 4 schematically shows the cassette tape and its feeding mechanism of the magnetic tape device 6. Five fixed reels 22, which do not rotate, are generally disposed inside the case 21. For example, a storage medium with a width of 1/2 inch (approximately 12.7 TV/rn,
) A magnetic tape 23 having a length of about 36 m is wound endlessly. When the cassette tape configured in this manner is loaded, the innermost tape of the tape 23 wound on the reel 22 is pulled out through the window 22a provided in the reel 22, and the capstan 24 and the pinch The roller 25 moves at high speed (jftr) in the direction of arrow a in the figure.
5rV/5ec) and then rewound again to the outermost circumference of the tape 23. therefore,
The tape 23 rotates once in about 7.2 seconds. One rotation of the tape 23 means that the tape 23 rotates as shown in FIG.
This is confirmed by optically detecting a tape mark 26 such as silver paper attached to the connecting portion 23h with a mark detector 27. In addition, the output signal of the detector 27 is determined by the block position on the tape 23 (described later).
It is also used as a standard for detecting As shown in FIG. 5, the tape 6-23 has 200 recording tracks (with a track width of approximately 40 μm) parallel to the running direction a.
m,) The inter-rack pitch is approximately 52 μm)28. Here, the recording tracks 28 are sequentially ro, 1, 2, . . . from the bottom track. ...198,199J
Of these, the two located approximately in the middle (track numbers r99 and 100J, track number "99" is a money-making track) are unique index information corresponding to one unit of image information. 198 of the remaining index recording tracks 2811 (track numbers 0 to 98, 101 to 199 ) is an information recording track 282 for recording (storing) image information.In addition, each recording track 28 is divided into 256 blocks in the length direction of the tape as shown in FIG.
Each block is sequentially ro, 1, 2, . . . with the tape mark 26 as a reference. ...254,255. J and a block number are assigned. Information signals are recorded on or reproduced from the tape 23 by a recording/reproducing head (a two-gap magnetic head with an erasing function) '9'i provided near the capstan 24, and by a head access mechanism (not shown) in the running direction. This is done by reciprocating in micron units in a direction perpendicular to a and selecting an arbitrary recording track 28.

Figure 6 (a), (b) and figure 7 (a) e (
b) shows the recording format of the index recording track 281. That is, as shown in FIG. 6(a), for 256 blocks, J<:::For example, the fourth

They are called second frame (2F) #third frame (3F), fourth frame (4F) s, etc. Note that the two blocks provided between each frame are used as invalid information areas (LG) for searching index information, which will be described later. In this embodiment, this invalid information area is a gap in which nothing is recorded, but for example, dummy information may be recorded therein. Therefore, each frame is

It consists of or).

Furthermore, each item (IT) has the following format configuration. In other words, in the case of normal mode (described later) in which normal documents are stored, 1
Index code consisting of alphanumeric symbols of up to 6 characters (
IDC), the track number (TNO) in which the image information with this index code name is recorded, and the first block number (B
(NO). In addition, in the case of a continuous mode (described later) 9- in which a series of consecutive documents is stored, an index code (
IDC) with a special code (
A continuous code consisting of P) and page information (FD) is added. This is the main point of the present invention, and the details will be explained later. By using such a recording format, in this embodiment, 256 pieces of index information constitute one unit of index information group, and these are recorded in one frame.

Now, using FIGS. 1 to 3, how image information is stored and retrieved is shown in FIG. 10(a).
This will be explained in detail below with reference to the flowchart shown in (b). First, in the input device 2, the 4 work keys Kt
(See Figure 2) and turn on the power to this device, the CPU (Central Processing Unit) Fuaffi tape device 6 will operate, and the tape 2
3 is run, the head 29 is positioned on the index recording track 281, and reproduction of the track 28110- is started. Then, the CPU 7 gives a transfer command for one frame to a DMA (direct memory access controller) 8, and the DMA 8 gives a playback command to the recording/playback circuit 9. Then, the recording/reproducing circuit 9 receives the reproduction signal from the head 29, and then the recording/reproducing circuit 9 receives the index recording track 28! When the DMA 8 detects the recording start index information (consisting of a special code and the recording start address at which all of the next new image information should be recorded) added after the last index information recorded in the The index information group in the frame in which the accepted recording start index information exists is directly stored in a first designated area of the RAM (random access memory) 10. Note that the first specified area has a storage capacity for 256 items constituting one frame.

Also, when the power is turned on by pressing 1 on the work key, the CPU 7 first displays the display device 3 in flow F1 as shown in FIG.
Display the guide text for a), rl,) Uroku J, r2. The operator is guided and instructed to select the desired mode from among ``Keep checking'' and ``3. Copy''. Therefore, the operator selects a desired mode using the numeric keypad 2 and the new line key Ks (see FIG. 2) on the input device 2. For example, "1. Touroku", which is mode ■,
To select all memory modes, press the 2 country key on the numeric keypad, and then press the new line key Ksk indicating that the mode has been selected. When 3 is pressed on the new line key in this way, the CPU 7 confirms in flow F2 that 3 is pressed in that key, and in flow F3,
Determine whether the selected mode is ■, ■, or ■. As a result of this determination, for example, if the storage mode mode ■ is selected, the CPU 7 displays the guidance text shown in FIG. 8(b) on the display device 3 in flow F4, and displays the document (
Instruct the operator to set the DOCo) PI on the two-dimensional scanning device 4. Based on this guide %FP
When 1 is set, the CPU 7 confirms that it has been set in flow F, and in flow F6, presses the continue key pressed in continuous mode from 4 (see Figure 2, hereinafter referred to as the continue key). It is determined whether a continuation flag (FCON?% or less is abbreviated as a continuation flag) set by a signal is set. In this case, since it has not been set yet, the CPU 7 displays the guidance text shown in FIG. 8(C) on the display device 3 in flow F7, and displays the index code (ID
The operator is guided and instructed to input C) and to set either a continuous mode in which a series of documents are stored continuously or a normal mode in which ordinary documents are stored. Therefore, the operator inputs the index code on the input device 2, presses 4 on the context key representing it when in continuous mode, and then presses the start key Ks (see Figure 2).
When in normal mode, press the start key instead of pressing 4 on the context key.

When the start key Ks is pressed in this way, the CPU 7 checks in flow F8 that 13- has been pressed on that key, and then inputs the index code (13-) in flow F9.
IDC) is entered, and the flow F't
At o, it is determined whether 4 is pressed on the context key. As a result of this determination, if 4 is not pressed on the context key (normal mode), CPU 7 resets the context flag in flow F'tt, and stores the input index code in a register provided in CPU F. It is temporarily stored in the temporary storage unit (MID) IJ, etc. That is, the storage format of the temporary storage unit 11 is, for example, as shown in FIG.
It corresponds to the item format in (b), and since this is the normal mode, the index code (IDC) is stored in the "0" to rFJ digits of the temporary storage unit 11 as shown in FIG. 9(a). It is something to do. Thus flow F
When the processing of il is completed, the CPU 7, in flow Flt, enters the track number (TNO) and block number (BN
O) When the power is turned on, the index information stored in the first designated area of the RAM 10 is read from the recording start index information in the index information group, and the information is stored in the temporary storage section 11 as shown in FIG. 9(a). “T,N
J and "B, N" are respectively stored in the J digits. When the processing of this flow F12 is completed, the CPU 7 operates the two-dimensional scanning device 4, and the image information from the secondary scanning device 4 is stored in the flow F'ts. the page buffer (P, B, )
12, and the contents of the page buffer 12 are supplied to the magnetic tape device 6 in flow F14.

That is, the two-dimensional scanning device 4 scans the set document P1.
is scanned two-dimensionally using laser light and photoelectrically converted.

This photoelectrically converted image information (video signal) is sent to a line buffer (
L, B, )14. The line information stored in the line buffer 14 is supplied to the signal compression circuit 15 via the selector 132, where the MH
Bandwidth compression is performed by (Modify-Hoffman) conversion, and then the page buffer 1 is
2 and are sequentially stored. Then, when all the image information for one unit (one page) is stored in the page buffer 12, the CPU 7 stores the track number (T) in the temporary storage section 11.
Head 2 up to the information recording track 28□ corresponding to NO)
9 is moved, and then the image information in the page buffer 12 is supplied to the head 29 via the selector 134 one scanning line at a time. Start recording image information.

After that, when all the image information for one unit has been recorded, C
The PU 7 reads the contents of a block counter (not shown) at that time and checks whether the value is smaller than the block number "254" of the last recordable block. Here, the block counter is provided in the CPUz, is cleared by the output of the mark detector 27, and is cleared by the clock pulse (period: about 28 yns) generated in synchronization with the running of the tape 23. It is designed to count from 0 to 255 J dimensions with one rotation of the tape 23.

As a result of the above check, if the value of the block counter is as small as "254", the content of the counter read out above, that is, the block number is multiplied by r+3J and is stored in RAM 10 along with the current track number. 2. If it is equal to "254", the above RA
The block number stored in M 1 o is set to "2" and the track number is set to 'er+I J. That is, without doing this, the recording start address at which the next new image information should be recorded is stored in the RAM 10. When one unit of image information has been stored in this way, the CPU 7 in flow F'ts temporarily stores the image information (temporary storage unit 1)
Index information (IDC.

TNO, BNO) is stored next to the last index information in the index information group in the first specified area of RAM 10. In this case, the index information for the first document is written by rewriting the recording start index information having a special code, and new index information is sequentially written from the next document onwards.

Therefore, when the processing of the above flow F'ts is completed, C
PU 7 returns to flow F4 again. This completes the storage process for one document, so the next document can be stored in two dimensions
By setting the inspection device w4, the flow F6 to F is started again.
Repeat steps up to 'ts and return to flow F4. In this way, in the normal mode where normal documents are stored one by one,
An index code is input for every 11 sentences.

When the desired number of documents have been stored in Bf, the operator presses the initialize key Kg (
(see Figure 2), CPU 7 is RAM
Next to the final index information of the index information group stored in the first specified area in 10, the special code and RA
Recording start index information consisting of a recording start address at which the next new image information stored in the second designated area in M lo is to be recorded is written. When this process is completed, the CPU 7 sends the head 29 to the index recording track 281 in order to store the new index information group for one frame edited as described above in the first specified area in the RAM JO. That track 2
8! and store the new index information. That is, the CPU 7 gives an erase command to the recording/reproducing circuit 9 and also gives a reverse transfer command for one frame to the DMA 8, so that the index information group before editing of the new index information group is stored. The new index information group is sequentially recorded in the frame via the recording/reproducing circuit 9 while the stored contents are erased by the head 29. Note that if the first specified area in RAM10 becomes full before the desired number of documents are stored, and if 256 pieces of index information are stored in the first specified area, the CPU 7 automatically stores the index information. The new index information group is stored in the index recording track 281 through the same storage operation as described above during storage of the image information.
to be recorded. Of course, at this time, storage of the image information is temporarily suspended.

The above explanation is for the case where 4 was pressed on the context key in flow FIO (normal mode), but the next time 4 was pressed on the context key (iFE#5? mode) h; ) 4. As a result of the determination in flow F1o, if 4 is pressed on the context key, it is a continuous mode in which a series of documents are stored consecutively.
The CPU 7 sets all the content flags in flow F16. In addition, the CPU 7 in this flow F16
), enter a special code (P
), rEJ and rEJ digits store page information (PD) indicating the entire first page, and digits "0" to "C" store index code (IDC) k, respectively. Thus flow F
When the processing in step 16 is completed, the CPU 7 sequentially proceeds to the flow Fil to F in the same way as in the normal mode described above.
Return to flow F4. This completes the storage process for the first page (first page) of a series of documents, and therefore the next second document (second page) can be set in the two-dimensional scanning device 4. , the process proceeds to flow F6 again to determine whether or not the conte flag is set. In this case, flow F1
Since it is set in 6, CPU7 is flow FIT.
8(d) is displayed on the display device 3 to instruct the operator whether or not to proceed in continuous mode.

At this time, the previously input index code and current page information (number of pages) are also displayed at the same time. therefore,
The operator presses 5 on the start key to continue in continuous mode, enters a new index code and presses 5 on the start key to switch to normal mode, and presses 5 on the start key to switch to continuous mode again with a different index code. Enter the index code and press 4 on the context key and the start key Ks k in sequence.

When the start key K11 is pressed in this way, the CPU 7
In the flow F'is, it is confirmed that the key has been pressed, and in the flow F19, it is determined whether an index code has been input. As a result of this determination, if the index code is input and 21-, the CPU 7 determines that the continuous mode is not to be performed and proceeds to the aforementioned flow FIG, and then proceeds to flow F'tt or flow F16. .

However, as a result of the above determination, if the index codes are being input, the CPU 7 determines that the continuous mode should be continued, and in flow F20, the page information in the temporary storage section 1 is incremented by "+1" and becomes "02". do. Note that since this is a continuous mode, the index code in the temporary storage section 1 remains unchanged without being rewritten.

Therefore, when the process of flow F20 is finished, the CPU
7 again proceeds to flows F'xt to F'ts and returns to flow F4. This completes the storage process for the second (second page) document in the series of documents, and by setting the next third document), repeats the same operation again.
The storage process for the third document ends. Thus 4
The same process is applied to the subsequent sheets. In this way, when storing a series of documents consecutively, enter the index code only for the first document, and then enter the index code for the second and subsequent documents. Just go. Therefore, each piece of index information in this case has the same index code and the page information is incremented one by one. That is, a continuous code (continuous page number) is added to a single index code and stored. Of course, if a series of documents are stored on the same information recording track, the track numbers will be the same and the block numbers will change for each document. Note that when the recording area of the information recording track runs out during storage, the track number is incremented by one, and the block number starts from the first, for example, "2".

When the series of documents has been memorized, by pressing 6 on the initialize key, the newly edited new document is stored in the first designated area of RAM 10 through the same processing operations as in the normal mode described above. The index information group is stored in the index recording track 281. Of course, even if the first designated area of the RAM 10 becomes full before storing a series of documents, the same processing operations as in the normal mode described above are performed. If mode ■ is selected, then the search mode
When mode ■ is selected, n))
1. As a result of the determination in flow F3, if mode ■ is selected, the CPU 7 displays the guidance text shown in FIG. Then, the operator is guided and instructed to set either a continuous mode in which a series of documents are searched continuously, or a normal mode in which ordinary documents are searched. Therefore, the operator inputs the index code and sequentially presses 4 on the context key and 6 on the start key in the continuous mode, and presses only 5 on the start key in the normal mode. When 6 is pressed on the start key,
The CPU 7 checks in flow F2 that the key has been pressed, checks that the index code has been input in flow F28, and checks whether 4 is pressed in the context key in flow F24. Determine whether As a result of this determination, if 4 is not pressed on the context key, the CP
U7 determines that it is the normal mode, resets the conte flag in flow F25, and stores the input index code in the "0" to "F" digits of the temporary storage section 1. When the process of flow F25 is completed in this way, C
By reproducing the recorded content of the index recording track 28H, the PU 7 compares it with the input index code in flow F26, and determines whether or not a matching index code exists in flow Fay.

That is, for example, if the third block (block number "3") of the tape 23 is currently passing through the head 29, the CPU 7 gives a transfer command for one frame to the DMA 8. Then, the DMA 8 accepts the reproduction signal from the head 29 by giving a reproduction command to the recording/reproducing circuit 9. Then, when the recording/reproducing circuit 9 detects a frame start code (EOL), the DMA 8 starts recording/reproducing. The reproduced signal received by the 2C generation circuit 9 and the index information group of the first frame are directly stored in the first specified area of the RAM 10. Then, when the recording/reproducing circuit 9 detects the frame encoder (EOF)k, the DMA 8 stops operating. Then, CPU 7 uses the first memory of RAM 10.
Each index code in the index information group of the first frame transferred to the designated area is compared and verified with the index code stored in the temporary storage unit 11 starting from one item, and the input index code in the temporary storage unit 11 is compared with the index code stored in the temporary storage unit 11. Determine whether there is an index code that matches . During this time, the invalid information area (LG) between the first frame and the second frame is passing through the head 29.

Therefore, when there is no matching index code in the first frame, the CPU 7
(c) After confirming that the second frame has not yet passed through the head 29, it again issues a transfer command for the next frame to the DMA 8. Then, through the same operation as in the case of the first frame described above, the index information group of the second frame is stored in the RAM 10, and comparison and verification are performed again. In this way the first
The frames are sequentially collated, and this collation operation is repeated until an index code that matches the input index code is found.

In the above verification, if an index code that matches the required index code (index code in the temporary storage unit 11) is not found, and the item corresponding to the index code is a special code is compared, the result will be more than this. Since no index information is recorded, the CPU 7 determines that the necessary index code almost exists, and determines whether or not the conte flag is set in flow F'zs. In this case, it is normal mode and the conte flag is not set, so an error is displayed and the oiler is notified of this.

On the other hand, in the above verification, if there is an index code that matches the required index code, the CPU
7 reads out the track number and block number following this matched index code from within the index information group stored in the first specified area of RAM 10, and stores them in the second specified area of RAM JO. When this process is finished, the CPU 7 in flow F29
Based on the track number and block number stored in the second designated area of 10, the corresponding image information is reproduced from the magnetic tape device 6 and temporarily stored in the page buffer 12, and the flow F
3 (l), the contents of the page buffer 12 are stored in the recording device 5.
supply to.

That is, the information recording track 28. corresponding to the track number stored in the second specified area of the CPU 7 RAM 1θ.
The head 29 is moved to the point where the track is played back. At this time, the block counter is operating, so if the count matches the block number stored in the second designated area of the RAM 10, the CPU 7 transfers the playback signal and block image information from that point on to the recording and playback circuit. 9 and selector x:j3q to be stored in the page buffer 12. When all the reproduced image information for one unit is stored in the easy buffer 12, the CPU 7 supplies the image information (compressed information) to the signal expansion circuit 16 for each scanning line. Bandwidth expansion is performed by inverse transformation to restore the original image information, which is sequentially supplied to the line buffer 14 via the selector 131. line buffer 14
The line information supplied to is sequentially supplied to the recording device 5 via the selector 132 as a serial information signal synchronized with the recording timing of the recording device 5, whereby the recording device 5 outputs reproduced image information as Bartco 2-P2. It is something to do. Therefore, when the processing of flow F'go is completed,
The CPU 7 determines whether or not the conte flag is set in flow F'st, and since it is not set in this case, the process returns to flow F'zt again. This completes the search process for one document, so by entering the index code of the next document to search, flow F'
Repeat steps from zz to F31 and return to flow F'gt.

In this way, in the normal mode in which normal documents are searched one by one, an index code is input for each document.

The above explanation is based on the context key 4 in flow F'z4.
is not pressed (normal mode), but next we will explain the case where 4 is pressed on the context key (continuous mode). As a result of the determination in flows F and 4, if 4 is pressed on the context key, it is a continuous mode in which a series of documents are searched continuously, so the CPU 7 executes flow F.
Set the contest flag at 'st. Also, CPU7
In this flow VSZ, the special code, the first negative page information "01", and the index code are respectively stored in the temporary storage section 1 as shown in FIG. 9(b), as in the storage mode described above. . When the processing of flow F33 is thus completed, the CPU 7 executes flow F33 in the same manner as in the normal mode described above. 6, the input index code is compared with the index code in the temporary storage section 11,
In flow F, 7, it is determined whether or not there is a matching index code 30-. In this case, since it is continuous mode, a special code and page information are added to the index code, so the verification in flow F26 includes not only the index code but also the special code and page information added to it. Match by shape. Then, if there is an index code that matches the required index code (index code in the temporary storage unit 11) in flow F27, the CPU 7 executes 7O-F29 to F'sx in the same way as in the normal mode described above. Then, in flow F'st, it is determined whether or not the conte flag is set. In this case, since it is continuous mode, it is set, so CPU 7 is in flow F.
'ss, r+IJ the page information in the temporary storage unit 11 and
2'' and returns to flow F26 again. This completes the search process for the first (first page) document in the series of documents.
The CPU 7 repeats the flow F26 to F3□→F'ss again to complete the search process for the second (second page) document. In this way, the third and subsequent sheets are processed in the same manner. In this way, when searching a series of documents continuously, by inputting the index code only for the first document, the series of documents are automatically searched and output.

When the search for a series of documents is completed, the determination result in flow F27 becomes inconsistent, so the CPU 7 determines that the search for the series of documents has been completed, and checks whether the content flag is set in flow Fi18. In this case, since it is set, the process returns to F'zt and prepares for the search operation for the next document.

In the embodiment described above, the page information in the continuous mode is automatically generated by the CPU 7, but it may also be possible, for example, to allow the operator to input settings by operating keys on the input device 2. .

Specifically, for example, when storing image information, instead of inputting page information for each piece of image information, the input page information may be stored in the temporary storage unit 11 in the flow Fill. In addition, when searching for image information, by inputting start page information and end page information that indicate the search cycle of searching from how many houses to how many houses, the input start page information can be used in the flow F' sz in the temporary storage unit 11, and the flow F'
Next to ss, check whether the value added to the page information by "+1" is larger than the end page information input above, and if it is smaller, return to flow F26, and if larger, return to flow F21. Bye. Further, in the above embodiments, a case has been described in which a magnetic tape device is used as the image information storage device, but the present invention can be similarly implemented in a case where, for example, an optical disk device using an optical disk is used as the storage medium.

As described in detail above, according to the present invention, when a series of continuous image information is stored, by adding and storing a continuous code to a single index code, each image information It is possible to provide an image information storage method in which there is no need to input an index code and only one representative index code is input, thereby improving operability and reducing operational errors.
