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.

2. Description of the Related Art Conventionally, as a method for storing and retrieving document images as they are, there is a method that records reduced images as they are on microfilm. 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, and these image signals can be stored on optical disks. Devices that record information using laser light and devices that store data at high density on magnetic storage media are being developed.

For example, with the latter type of magnetic storage media, thousands 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 has become very convenient. Furthermore, the storage location of the document image can be stored as an index code on the same magnetic tape, and by inputting this index code as necessary, 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 individual information of an employee at a company, there is no problem in storing each document with its own index code added each time. When you want to memorize pages 1 to 10 of a book, you have to enter the index code corresponding to the book and the code representing the page for each page, even though it is a series of documents. There must be. Also, when storing patent publications, for example, if the patent number is used as an index code, a page code must be added to that index code to form one index code, so a document image must be stored as one page. You must enter the patent number and page code as the index code each time you enter the number. 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 circumstances, and its object is to be able to store a series of image information without inputting index information for each individual image information, and to store a series of image information without inputting index information for each individual image information. An object of the present invention is to provide an image information storage method that can accurately store information.

An embodiment of the present invention will be described below with reference to the drawings.

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
performs editing processing such as recording, reproducing, adding, inserting, and deleting image information and index information in accordance with input information from an input device 2 such as a keyboard. The display device 3 is, for example, a CRT display device, and under the control of the control device 1 provides various operational guidance or visually displays input information and output information as needed. It is configured integrally with the input device 2. Image information P ₁ such as a document is two-dimensionally optically scanned and photoelectrically converted by a two-dimensional scanning device (Scana, SC.) 4, and this photoelectrically converted image information (video signal) is sent to a control device. 1 to a recording device (printer, PR.) 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 . . Note that the input device 2 is, for example, a second input device.
The keyboard layout is as shown in the figure.

FIG. 4 schematically shows the cassette tape and its feeding mechanism of the magnetic tape device 6. A fixed reel 22 that does not rotate is provided in the case 21, and this reel 22 is used as a storage medium. For example, a magnetic tape 23 with a width of 1/2 inch (approximately 12.7 mm) and a length of approximately 36 m is wound endlessly. When the cassette tape configured as described above 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 roller are pulled out. 25 at a high speed (approximately 5 m/sec) in the direction of the arrow s shown in the figure, and then rewound again to the outermost portion of the tape 23. Therefore, tape 23 is about 7.2
It will rotate once in seconds. This tape 23-1
The rotation is performed using a tape mark 2 such as silver paper attached to the connection part 23a of the tape 23 as shown in FIG.
6 is confirmed by optically detecting it with a mark detector 27. The output signal of the detector 27 is also used as a reference for detecting the position of a block on the tape 23 (described later). However, tape 23
As shown in Figure 5, there are 200 recording tracks parallel to the running direction a (the track width is approximately
40 μm, and the track-to-track pitch is approximately 52 μm)28. Here, the above recording track 28
is sequentially "0, 1, 2," from the bottom track.
…198, 199” and track numbers are given.
Of these, the two located approximately in the center (track numbers ``99, 100'', track number ``99'' is a spare track) contain index information consisting of a unique index code corresponding to one unit of image information, and The index recording track ₂₈₁ records (memorizes) recording addresses consisting of numbers and block numbers, and the remaining 198 tracks (track numbers ``0~''
98, 101 to 199'') serves as an information recording track ₂₈₂ for recording (storing) image information. Also,
Each recording track 28 is divided into 256 blocks in the length direction of the tape, as shown in FIG.
Each block is given a block number "0, 1, 2, . . . 254, 255" in order with the tape mark 26 as a reference. In order to record or reproduce information signals on the tape 23, a recording/reproducing head (a two-gap magnetic head with an erasing function) 29 provided near the capstan 24 is moved in the running direction a by a head access mechanism (not shown).
This is done by reciprocating in micron units in the direction b orthogonal to the direction b and selecting an arbitrary recording track 28.

6a, b and 7a, b show the recording format of the index recording track ₂₈₁ . That is, as shown in Figure 6a, 256
For example, every 3 blocks from the 4th block, that is, the 4th, 7th, 10th,
Index information is recorded in the 13th, .
It is called F. Note that the two blocks provided between each frame are invalid information areas LG for searching index information, which will be described later.
Although this invalid information area is a gap in which nothing is recorded in this embodiment, dummy information may be recorded therein, for example. Therefore, each frame has a frame start code as shown in Figure 6b.
EOL, 256 items IT from 1st to 256th,
Horizontal parity check code VP, recording gap GAP, and frame end code
Starting from EOF.

In addition, each item IT has the following format configuration. That is, in the case of normal mode (described later) in which normal documents are stored, an index code IDC consisting of alphanumeric symbols of up to 16 characters is used as shown in Figure 7a, and image information having this index code name is recorded. track number
TNO, and the first block number BNO in which this image information is recorded. In addition, in the case of continuous mode (described later) in which a series of consecutive documents is stored, as shown in Figure 7b, a special code P indicating that the documents are consecutive is added to the index code IDC, and a serial number is added. A continuous code consisting of page information PD 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 form one unit of index information group, which is recorded in one frame.

Now, using Figures 1 to 3, we will explain how image information is stored and retrieved in the first part.
This will be explained in detail below with reference to the flowcharts shown in Figures 0a and 0b. First, by pressing the power key K ₁ (see Figure 2) on the input device 2 and turning on the power of this device, the CPU (Central Processing Unit) 7 operates the magnetic tape device 6 and prints the tape 23. While running, the head 29 is positioned on the index recording track ₂₈₁ , and reproduction of that track ₂₈₁ is started. Then, when the CPU 7 gives a transfer command for one frame to a DMA (direct memory access controller) 8, the DMA 8 gives a playback command to the recording/playback circuit 9. Then, the recording/reproducing circuit 9
accepts the playback signal from the head 29, and then the recording/playback circuit 9 reads the recording start index information (special code and next new image information) added next to the last index information recorded in the index recording track ₂₈₁ . and the recording start address to be recorded), the DMA 8 directly stores the index information group in the frame in which the recording start index information accepted by the recording/reproducing circuit 9 exists in a RAM (random access memory).
10 in the first specified area. Note that the first designated area is the 256 areas constituting the one frame.
It has a storage capacity for 2 items.

Also, when the power key K ₁ is pressed and the power is turned on, the CPU 7 first turns on the display device 3 in flow F ₁ .
Display the information in Figure 8a on the screen, and read "1. Touroku".
The operator is guided and instructed to select the desired mode from "2. Check" and "3. Copy." Therefore, the operator selects a desired mode using the numeric keypad _K2 and the new line key _K3 (see FIG. 2) on the input device 2. For example, to select the mode ``1.Record'', that is, the memory mode, press the □1 key on the numeric keypad K ₂ , then press the New Line key K ₃ to indicate that the mode has been selected.
This is what you press. Thus the new line key
When _K3 is pressed, the CPU 7 confirms that the key _K3 is pressed in flow _F2 , and determines which of the following modes is the selected mode in flow _F3 . As a result of this determination, for example, if a storage mode is selected,
In flow _F4 , the CPU ₇ displays the guidance text shown in FIG.
When document P ₁ is set based on this guide, the CPU
7 confirms that it has been set in flow _F5 , and in flow _F6 , the controller is set by a signal from the continue key _K4 (see Figure 2, hereinafter abbreviated as the context key) that is pressed in continuous mode. It is determined whether a tenu flag (F _CONT , hereinafter abbreviated as conte flag) is set. in this case,
CPU7 is not set yet, so CPU7
At F ₇ , display the guidance text in Figure 8 e on the display device 3,
The operator is guided and instructed to input an index code IDC of up to 16 digits representing the name of the document image, and to set either continuous mode in which a series of documents are stored continuously or normal mode in which ordinary documents are stored. Therefore, the operator inputs the index code on the input device 2, presses the context key K ₄ representing it when in continuous mode and then presses the start key K 5 (see Figure 2), and presses the start key K ₅ (see Figure 2) when in normal mode. Press the start key K ₅ without pressing the context key K ₄ .

When the start key K ₅ is pressed in this way, the CPU
7 confirms that the key _K5 is pressed in flow _F3 , confirms that the index code IDC is input in flow _F9 , and presses the context key _K4 in flow _F19 . Determine whether or not the
As a result of this determination, if the context key K ₄ is not pressed (normal mode), CPU 7 switches to flow F _11.
At the same time, the input index code is temporarily stored in a temporary storage unit MID11 such as a register provided in the CPU7. That is, the storage format of the temporary storage section 11 corresponds to the item format of FIGS. 7a and 7b, for example, as shown in FIGS.
As shown in Figure a, the index code IDC is stored in the "0" to "F" digits of the temporary storage section 11. When the processing of flow F ₁₁ is completed in this way,
In flow _F12 , the CPU 7 checks the track number that constitutes the recording start address at which new image information should be recorded.
TNO and block number BNO at power-on.
The recording start index information in the index information group stored in the first specified area of the RAM 10 is read out and stored in the "TN" and "BN" digits of the temporary storage section 11, respectively, as shown in FIG. 9a.
When the processing of this flow _F12 is completed, CPU7
The dimensional scanning device 4 is operated, the image information from the two-dimensional scanning device 4 is temporarily stored in the page buffer (PB) ₁₂ in flow F13, and the contents of the page buffer ₁₂ are supplied to the magnetic tape device 6 in flow F14. do.

That is, the two-dimensional scanning device 4 scans the set document _P1 two-dimensionally using a laser beam,
Convert photoelectrically. This photoelectrically converted image information (video signal) is sent to a selector 13 for each scanning line.
₁ and is temporarily stored in a line buffer (LB) 14. The line information stored in the line buffer 14 is supplied to the signal compression circuit 15 via the selector ₁₃₂ , where it is subjected to band compression by well-known MH (Modified-Hoffman) conversion, and then via the selector _133. The data is then supplied to the page buffer 12 and sequentially stored. and,
When all the image information for one unit (one page) is stored in the page buffer 12, the CPU 7 moves the head 29 to the information recording track ₂₈₂ corresponding to the track number TNO in the temporary storage section 11, and then the page buffer 12 is stored. The image information in 12 is sent to the head 29 via the selector ₁₃₄ for each scanning line.
By supplying the image information to the block number BNO in the temporary storage unit 11, recording of the image information is started from the block corresponding to the block number BNO.

After that, when all the image information for one unit has been recorded, the CPU 7 reads the contents of the block counter (not shown) at that point and checks whether the value is smaller than the block number "254" of the last block that can be recorded. Check. Here, the block counter is provided in the CPU 7,
Cleared by the output of the mark detector 27, the tape 2
The count is increased by a clock pulse (period: about 28 ms) generated in synchronization with the running of the tape 23, and one rotation of the tape 23 counts from 0 to 255. As a result of the above check, if the value of the block counter is smaller than "254", the content of the read counter, that is, the block number is incremented by "+3" and the track number at this time is added to the second designation of RAM10. If it is stored in the area and equal to "254", the above RAM10
The block number stored in the track number is set to "2" and the track number is set to "+1". That is, by doing this, the recording start address at which the next new image information is to 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 _F15 ,
Index information IDC in the temporary storage unit 11,
TNO and BNO are stored next to the final index information in the index information group in the first specified area of the 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. When the process of flow _F15 is completed, the CPU 7 returns to flow _F4 again. This completes the storage process for one document, and by setting the next document in the two-dimensional scanning device 4, the process returns to flow F ₆ -
Repeat steps up to F ₁₅ and return to flow F ₄ . In this way, in the normal mode in which normal documents are stored one by one, an index code is input for each document.

When the desired number of documents have been stored, the operator presses the initialize key K ₆ (see Figure 2) on the input device 2, and the CPU 7 is activated.
After the final index information of the index information group stored in the first specified area in RAM 10, the special code and the next new image information stored in the second specified area in RAM 10 are to be recorded. Writes recording start index information consisting of an address. When this process is finished,
The CPU 7 writes the new index information group for one frame edited as described above in the first specified area in the RAM 10 to the index recording track 28.
₁ to its track 2.
8 to ₁ and store the above new index information. That is, the CPU 7 gives an erase command to the recording and reproducing circuit 9 and also gives a reverse transfer command for one frame to the DMA 8, so that the new index information group is stored in the frame in which the index information group before editing is stored. The new index information group is sequentially recorded via the recording/reproducing circuit 9 while the contents are erased by the head 29. Note that if the first designated area in the RAM 10 becomes full before the desired number of documents have been stored, that is, if 256 pieces of index information are recorded in the first designated area, the CPU 7 automatically stores the index information. The new index information group is recorded in the index recording track ₂₈₁ through a storage operation similar to that described above during storage of the image information. Of course, at this time, storage of the image information is temporarily suspended.

The above explanation is based on the context key in flow F ₁₀ .
This is the case where K ₄ is not pressed (normal mode), but next we will explain the case where the context key K ₄ is pressed (continuous mode). If the result of determination in flow _F10 is that the context key _K4 has been pressed, the CPU 7 sets a context flag in flow _F16 , since the continuous mode is in which a series of documents are stored continuously. Also, CPU7 uses this flow F ₁₆
, "D" in the temporary storage section 11 as shown in FIG. 9b.
A special code P is stored in the digits, page information PD is stored in the "E" and "F" digits, "01" indicates the first page, and an index code IDC is stored in the "0" to "C" digits, respectively. When the process of flow F ₁₆ is thus completed, the CPU 7 sequentially proceeds to flows F ₁₂ to F ₁₅ in the same manner as in the normal mode described above, and then returns to flow F ₄ . This completes the storage process for the first document (page 1) in the series of documents, and by setting the next document (page 2) in the two-dimensional scanning device 4, it can be read again. Proceeding to flow _F6 , it is determined whether the content flag is set. In this case the flow F ₁₆
CPU7 is set in flow _F17 .
8d is displayed on the display device 3 to instruct the operator whether or not to continue the continuous mode. Note that at this time, the previously input index code and current page information (number of pages) are displayed at the same time. Therefore, the operator must press the start key K ₅ if he wants to continue in continuous mode, or enter a new index code and press start key K ₅ if he wants to switch to normal mode.
To enter continuous mode again with a different index code, enter the new index code and press the context key _K4 and start key _K5 in sequence.

When the start key K ₅ is pressed in this way, the CPU
7 confirms that the key _K5 has been pressed in flow _F18 , and determines whether an index code has been input in flow _F19 . As a result of this determination, if the index code is input,
The CPU 7 determines that the continuous mode is not to be performed and proceeds to the aforementioned flow _F10 , and then proceeds to flow _F11 or flow _F16 . However, as a result of the above determination, if no index code has been input, the CPU 7 determines that the continuous mode should be continued, and in flow _F20 , the page information in the temporary storage unit 11 is incremented by "+1" to "02". shall be.
Note that since this is a continuous mode, the index code in the temporary storage section 11 remains unchanged without being rewritten. When the processing of flow _F20 is completed, the CPU 7 again processes flows _F12 to _F15.
and return to flow F ₄ . This completes the storage process for the second document (page 2) in the series of documents, and then sets the next third document, repeats the same operation, and stores the third document. The memory processing for is completed. In this way, the fourth and subsequent sheets are processed in the same manner. In this way, when storing a series of documents consecutively, you only need to enter the index code for the first document, and from the second document onwards, you only need to perform the memorization operation without inputting the index code. . Therefore, each piece of index information in this case has the same index code and page information 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 number will be the same and the block number 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 very beginning, for example, "2".

When the series of documents has been memorized, pressing the initialize key _K6 causes the memory to be stored in the RAM through the same processing operations as in the normal mode described above.
The new index information group edited in the first designated area of 10 is recorded on index recording track 2.
8 Store in ₁ . Of course, even if the first designated area of the RAM 10 becomes full before a series of documents are stored, the same processing operations as in the normal mode described above are performed.

The above explanation is for the case where the storage mode is selected in flow _F3 , but
Next, a case where a search mode is selected will be described. As a result of the determination in flow F ₃ , if the mode is selected, the CPU
7 displays the guidance text shown in FIG. 8 e on the display device 3 in flow F ₂₁ , inputs the index code of the image information to be searched, and selects the continuous mode in which a series of documents are continuously searched or the normal mode. The operator is guided and instructed to set the normal mode for searching documents. Therefore, the operator enters the index code and, when in continuous mode, the context key K ₄
and start key K ₅ in sequence; in normal mode, press only start key K ₅ . When the start key _K5 is pressed, the CPU 7 confirms that the key _K5 has been pressed in flow _F22 , confirms that the index code has been input in flow _F23 , and proceeds to flow _F24. , it is determined whether or not the context key _K4 is pressed. As a result of this determination, if the context key _K4 is not pressed, the CPU 7 determines that the mode is normal, resets the context flag in flow _F25 , and stores the input index code in the temporary storage section 11. "0" ~ "F"
Store in digits. When the process of flow _F25 is completed, the CPU 7 records the index recording track 2.
8 By reproducing the recorded content in ₁ , flow F ₂₆
In step F27, it is compared with the input index code, and in flow _F27 it is determined whether a matching index code exists.

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 will
Give a frame transfer command. Suroo, DMA
8 accepts the reproduction signal from the head 29 by giving a reproduction command to the recording and reproduction circuit 9, and then the recording and reproduction circuit 9 receives the frame start code.
When EOL is detected, the DMA 8 directly stores the reproduction signal accepted by the recording/reproduction circuit 9, that is, the index information group of the first frame, in the first specified area of the RAM 10. Then, when the recording/reproducing circuit 9 detects the frame end code EOF, the DMA 8 stops operating. Then, the CPU 7 sequentially compares each index code in the index information group of the first frame transferred to the first designated area of the RAM 10 with the index code stored in the temporary storage unit 11, starting from one item, and temporarily It is determined whether or not there is an index code in the storage unit 11 that matches the input index code. During this time,
The invalid information area LG between the first frame and the second frame passes through the head 29. However,
When matching the first frame, if there is no matching index code, the CPU
After confirming that the second frame has not yet passed through the head 29, the controller 7 issues a transfer command for the next frame to the DMA 8 again. Then,
After the same operation as 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 matching is performed sequentially from the first frame, and this matching operation is repeated until an index code that matches the input index code is found.

In the above verification, the index code required (index code in the temporary storage unit 11)
If no index code is found that matches the index code, and the item corresponding to the index code is a special code is compared, no more index information is recorded, so
The CPU 7 determines that the required index code does not exist, and determines in flow _F28 whether or not the content flag is set. In this case, since it is the normal mode and the content flag has not been set, an error display is performed and the operator is notified of this.

On the other hand, if an index code that matches the required index code is found in the above verification, the CPU 7 calculates the track number and block number following the matched index code.
The index information group stored in the first specified area of RAM10 is read out and stored in RAM1.
0 in the second specified area. When this process is completed, the CPU 7, in flow _F29 , reproduces the corresponding image information from the magnetic tape device 6 based on the track number and block number stored in the second designated area of the RAM 10, and temporarily stores it in the page buffer 12. In flow _F30 , the contents of the page buffer 12 are supplied to the recording device 5. In other words, CPU7
The head 29 is moved to the information recording track ₂₈₂ corresponding to the track number stored in the second specified area of the RAM 10, and reproduction of that track is started. At this time, since the block counter is operating, if the count matches the block number stored in the second designated area of RAM 10,
The CPU 7 stores the reproduced signal from that point, that is, the image information, in the page buffer 12 via the recording/reproducing circuit 9 and the selector ₁₃₃ . Then, when all the reproduced image information for one unit is stored in the page buffer 12, the CPU 7 supplies the image information (compressed information) to the signal expansion circuit 16 for each scanning line, thereby increasing the bandwidth by MH inverse conversion. Decompress and return to the original image information, selector 1
3 ₁ to the line buffer 14 in sequence.
The line information supplied to the line buffer 14 is
The information 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, so that the recording device 5 outputs the reproduced image information as a hard copy _P2 .
However, when the processing of flow F ₃₀ is finished, the CPU
In step 7, it is determined in flow _F31 whether or not the content flag is set, and in this case, since it is not set, the flow returns to flow _F21 again. This completes the search process for one document. By inputting the index code of the next document to be searched, steps _F22 to _F31 are repeated again.
Return to _F21 . 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 explained using the context key in flow _F24 .
This is the case where K ₄ is not pressed (normal mode), but next we will explain the case where the context key K ₄ is pressed (continuous mode). If the result of determination in flow _F24 is that the context key _K4 has been pressed, the CPU 7 sets a context flag in flow _F32 , since the continuous mode is in which a series of documents are searched continuously. Also, CPU7 uses this flow F ₃₂
9b, as in the storage mode described above.
A special code, page information "01" for the first page, and an index code are stored in the temporary storage unit 11 as shown in FIG. When the process of flow _F32 is thus completed, the CPU 7 compares the input index code, that is, the index code in the temporary storage unit 11, with the input index code in flow _F26 , as in the case of the normal mode described above, and executes flow F32. In _{step 27} , it is determined whether a matching index code exists. 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. Check in a form that also includes. Then, when an index code that matches the required index code (the index code in the temporary information section 11) is found in flow _F27 , the CPU 7 returns to flow _F29 in the same way as in the normal mode described above. ~
The process proceeds sequentially to _F31 , and in flow _F31 it is determined whether or not the content flag is set. In this case, since it is a continuous mode, it is set, so the CPU 7 adds "+1" to the page information in the temporary storage section 11 to "02" in flow _F33 , and then returns to flow _F26.
Return to This completes the search process for the first document (first page) in the series of documents, and the CPU 7 repeats the flow F ₂₆ to F ₃₁ →F ₃₃ again.
The search process for the second (second page) document ends. In this way, the third and subsequent sheets are processed in the same manner. In this manner, when a series of documents is to be searched continuously, the series of documents are automatically searched and output by inputting the index code only for the first document.

After searching a series of documents, the flow
Since the discrimination result in F ₂₇ is inconsistent, the CPU
7 determines that the search for a series of documents has been completed,
In flow _F28 , it is determined whether or not the content flag has been set. In this case, since it has been set, the process returns to flow _F21 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 the operator may input and set it by operating keys on the input device 2, for example. Specifically, for example, when storing image information, page information may be input for each image information, and the input page information may be stored in the temporary storage unit 11 in flow _F16 .

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 implemented in the same way, for example, in the case where an optical disk device using an optical disk is used as the storage medium.

As described in detail above, according to the image information storage method of the present invention, when storing a series of image information for a single index information, by storing the series numbers in association with each other, each image information There is no need to input index information, and only one representative index information needs to be input, improving operability and reducing operational errors. In addition, when storing a series of image information, by displaying the serial number (page information) along with index information, it is possible to check how many pages are currently stored, and the series of image information can be stored accurately. be able to.
