Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image information storage and retrieval device that stores image information in a searchable manner based on search information corresponding to the image information.

[Technical background of the invention and its problems]

Recently, image information such as documents that are generated in large quantities is read by optical two-dimensional scanning, and this read mt! II information is sequentially stored in a storage medium such as an optical disk, or image information from another terminal device from the communication control device' is sequentially stored in the optical disk, and search information for each example of the image information is also sequentially stored, An image information storage and retrieval device has been developed and put into practical use that searches and reads image information stored on an optical disk by inputting this search information, and outputs it in a state where it can be visually viewed on an output device such as a CRT display device or a recording device. ing.

By the way, in this type of device, image information is managed so that it can be easily searched. For example, if we consider a basic filing system using paper files, Figure 1 (
As shown in a), a page IA is the smallest unit in which information is written, a document 1B is a collection of pages 1A in which information of the same nature is written, a binder 1G is a collection of documents 1B of the same nature, and a binder Cabinet 1D is a collection of 1C, sentences are a collection of cabinets 1D! It is systematized and managed on the 1st floor of the rack. The image information storage and retrieval device also follows the fundamental concept of a filing system using paper files, for example, as shown in Figure 1(b).
As shown in the figure, one image information 2A is the smallest unit of information stored on an optical disc, an image information document 2B is a collection of image information with the same property, an image information binder 2G is a collection of image information documents with the same property, and an image information binder 2A is a collection of image information documents with the same property. They are systematized and managed as an image information cabinet (one side of an optical disc) 2D, which is a collection, and an optical disc crack (optical disc cassette or optical disc autochanger), which is a collection of optical discs. Note that this type of image information management system does not physically divide the image information storage area according to the management system, but rather stores search information corresponding to individual image information on other storage means for each set of image information. This is generally done by reconfiguring the

In addition, there are cases where it is necessary to maintain the confidentiality of input and output image information, and in order to meet such requests, the same image information document 2B or image information paper file 2C shown in FIG. 1(b) must be kept confidential. When accessing image information for the purpose of searching or registering image information by setting password information in advance for each file, which is a collection unit of image information having a property, first access the file containing the image information to be accessed. The system is configured so that the staff member inputs the user's name and the password information for the file, checks this against preset password information, and allows the staff member to access the image information only when they match.

However, with the above configuration, when attempting to access a plurality of files, it is necessary to remember the password information for each file and enter it sequentially, which is extremely inconvenient.

[Purpose of the invention]

Now that the detailed configuration of the magnetic disk 15 has been clarified, the explanation will continue based on FIG. Image information is stored and searched for the unit of image information corresponding to the password information only when it matches any of the password information group (in-apparatus common secret code and various file secret codes) stored on the disk 15. A control means (hereinafter referred to as CPLJ) 17 is provided. This CPU 17 is the control unit 1
8, and in addition, this control section 1
8 includes a main memory 19, a buffer 7 memory, for example, a page buffer 20, which has a storage capacity corresponding to image information for at least one page of the original, compression (reducing redundancy) and expansion (reducing redundancy) of image information; A compression/expansion circuit 21 for performing (undoing), a pattern generator 22 storing pattern information such as characters and symbols, and a display interface 23 are provided. In addition, in the apparatus of this embodiment, the two-dimensional scanner 10 reads the data, and the CPU 17
A recording device 25 outputs as a hard copy image information supplied via the optical disc 13 or read from the optical disc 13 and supplied via the CPU 17, and displays this image information via the display interface 23. CR7 display (e.g. cathode ray tube display)
26 are provided.

Note that the CPL 117 stores image information based on the password information input via the operation unit 12 as described above.
In addition to controlling search permissions, it also stores image information,
When the search is permitted, each section is controlled based on input information and operation commands from the operation section 12.

For example, when registration and storage of image information is requested, the image information from the two-dimensional scanning device 10 is stored in a predetermined storage area on the optical disk 13, and the search information (image information name) input from the operation unit 12 is stored. is stored in a predetermined storage area of the magnetic disk 15 that is organized into a management system together with the storage start address of the image information on the optical disk. Note that storage on the magnetic disk 15 is performed during the scanning time of the original 11 in the two-dimensional scanning device 10. When a search for image information is requested, the search information input from the operation unit 12 is compared with the search information stored in the magnetic disk 15, and if a match is found, the image information corresponding to the search information is checked. is read from the optical disc 13 and output to the CR7 display section 26 or the recording device 25.

Next, the operation of the apparatus of the above embodiment will be explained.

First, there are five types of image information stored in the optical disc 15 before the start of operation: image information 1-11, image information 1-22, image information 1-31, image information 2-1°, and image information 2-2. The search information (image information name) of these image information and the storage start address of the image information stored on the optical disk are stored in file 1. as shown in FIG. 4(b). Each file 2 is systematized and stored and managed on the image information search table area 32 on the magnetic disk 15, and the file 1 name, file llll 1 secret code, file 2 name and file 2 secret code are shown in FIG. 4(a). As shown, the information is stored in the file information search table area 31 on the magnetic disk 15, and the internal secret code and the next image information storage start address at which the next image information storage can be started on the optical disk are also stored in the file information search table area 31 on the magnetic disk 15. The information is stored in a predetermined storage area on the magnetic disk 15 as shown in FIG.

Here, for example, FIG. 5(a) shows a case where a staff member accesses image information from file 2.

This will be explained with reference to the flowcharts shown in (b) and (c).

First, enter the file name to be used from the operation section 12, for example, "
File 2 name" is input (step S1), and then a secret code is input from the operation section 12 (step S1).
2) "Internal common secret code" from the magnetic disk 15
is read (step S3), and it is determined whether the read out "common secret code within the device" matches the input secret code (step 84). If there is a discrepancy, the file secret code corresponding to the file name input from the operation unit 12, that is, the "File 2IN secret code" is written to the magnetic disk 1.
5), and it is determined whether the read [file 2 secret code] matches the input secret code (step S6). If they do not match, the CRT display section 26 displays a message to the effect that the entered secret code is incorrect (step Sr).

When it is determined in either step S4 or step SH that the confidential codes input from the operation unit 12 match, the matching code is, for example, a file confidential code for the set of image information corresponding to the confidential code. If there is a file that corresponds to this, and if there is a match that is a common secret code within the device, access to image information will be permitted for all files, and the business name, that is, the operation command instructed from the operation unit. is input (step Ss). In the case of the apparatus of this embodiment, the operations are broadly divided into registration and search, so it is determined whether the input operation name is registration (step Sa).

If it is determined that the image information has been registered, the process moves to the flow shown in FIG. While inputting the image information to be registered, ie, "image information 2-3" via the two-dimensional scanning device @10, the image length is calculated at the same time (step 811).
. Then, the next image information storage start address on the optical disk is read from the magnetic disk 15 (step 5).
12) The image information inputted in step Stt is started to be written on the optical disk 13 after this next image information storage head address (step 518). Note that when image information read by the two-dimensional scanning device 10 is stored on the optical disk 13, the read image information is stored in the page buffer 20, and the image information stored in the page buffer 7720 is compressed for each line information. Extension circuit 21
The band is compressed by the well-known MH (Modified Hoffman) conversion, and the compressed line information 111 is supplied to the optical disk device 14 and the image information is stored in the optical disk 13. Then, in the image information search team area 32 of the magnetic disk 15 in which image information is stored on the optical disk 13, an area of the file that is currently being registered, that is, file 2 (image information search table area 32ε2 for file 2) is stored. ), and in step 814), the image information name, that is, "Image information name 2 -3" and stores the storage start address of this "image information 2-3" on the optical disk, that is, the [next image information storage start address] stored on the magnetic disk 15 in the image information search table for file 2. Area 32E2 image information 2
-3 storage start address storage area 3282-3 (step 515). In this way, image information 2-3
After completing the filling, the image length of the current image information 2-3 is adjusted to the [next image information storage start address] stored in the magnetic disk 15 in step SIG.
>, the value in the next image information storage head address storage area 33 is replaced with the value after the above addition (step 817), and the registration process for image information 2-3 is completed.

When it is determined in step S9 that the search is to be performed, the process moves to the flow shown in FIG.
(step 820). Then, all the image information names included in the currently accessible file, for example, file 2, in the image information search table area 32 of the magnetic disk 15 are sequentially read (step 821), and the image information names to be read are input in step 820. (Step 5)
22). If they match as a result of this determination, the image information storage start address corresponding to the image information name is read from the magnetic disk 15 (step 523), and the image information is read from the optical disk 13 based on this start address (step 524). ) This is displayed on the CRT display section 26 (step 525).If there is no match as a result of the determination in step 822, the corresponding image information is heated to C.
It is displayed on the RT display section 26 (step 826). Note that when reading the image information from the optical disk 13, the compressed image information from the optical disk device 14 is supplied to the companding path for each scanning line, and the band is expanded by MH inverse conversion to obtain the original image information. This image information is sequentially supplied to the page buffer 20, and this image information is displayed on the CRT display unit 26 via the display interface 23.

As is clear from the above description, in the device of this embodiment,
If it is necessary to access image information within the range of all image information contained in all files, if a specific staff member memorizes one common secret code within the device, he or she can access the entire system, and at the same time The file security code set for each file makes it possible to maintain the confidentiality of each file for general staff.

Note that the above-mentioned internal common secret code and each file secret code can also be set for each job.

If the secret code is set in this way, Figure 5 (a)
Step S9 shown in FIG. 1 may be executed immediately after the start, and then the operations from step S1 onward may be executed for each task.

Next, a second embodiment of the present invention will be described.

Detailed explanations of the same configurations as in the first actual flow example will be omitted.

The first difference is the management system for image information stored on the optical disc 13. Basically, 1st (a) and (b)
As explained above, this system is based on the basic concept of the filing system using paper files, and the first unit (referred to as a file) is one image information as the minimum unit, and a group of image information with the same properties as one unit. A filing system for image information is established by using a second unit that includes a plurality of the first units, for example, a unit of a replaceable information storage medium (for example, one side of an optical disk) (hereinafter simply referred to as a medium). It is built.

This filing system is constructed on the magnetic disk 15, and the details of this magnetic disk 15 will be explained here.

FIG. 6 is a memory map showing an overview of the storage area of the magnetic disk 15. This magnetic disk 15 stores a media information search table area 41, a file information search table area 42, an image information search table area 43, and the next image information storage start address at which the next image information storage can be started on the optical disk 13. Next image information storage start address storage area 44.

FIG. 7(a) shows the above media information search table area 4.
1 is a memory map showing details of 1. This allows the media information of all media, such as the media name and the second secret information set for each media (hereinafter simply referred to as the media common location code), to be stored as a pair.
For example, Metsu 4fu 1 name storage area 41A1 that stores Tade 4fu 1 name. Media 1 common secret code storage area 41B that stores the media 1 common secret code corresponding to media 1! , . . . A media n name storage area 41An for storing a media n name, and a media n common secret code storage area 418n for storing a media n common secret code corresponding to the medium n are sequentially provided.

Figure 7<b) shows the above file information search table area 4.
This is a memory map showing details of 2. This is the file search table area 42E for media 1 for each media.
, File search table area 43ε2 for media 2
．． . . . File search table area 42E for media n is divided into two areas, and each area contains file search information corresponding to each file, such as file name and first password information set for each file (hereinafter referred to as (simply referred to as a file secret code) can be stored in pairs.

For example, the file 1-1 name storage area 42A1-1 that stores the file 1-1 name. File 1-1 corresponding to file 1-1 File 1-11 storing confidential code
1 secret code storage area 42at-1, . . ., file 1-n name storage area 42At-n that stores the file l-n name, stores the file 1-n secret seed corresponding to the file 1-n. Files 1-n confidential code storage area 42B are sequentially removed, and file search table area 42E2 for other media is opened.・・・・・・、
A similar storage area is also configured in En.

FIG. 7(C) is a memory map showing details of the image information search table area 43. First, this is divided into media-specific image information search table area 43E t for media 1, image information search table area 43ε2 for media 2, and so on. . . . Image information search table area 43εn for media n is configured, and then image information search table area 43E t for each medium, . . .
・The 43E port is divided for each file. For example, the image information search table area 43E1 for media 1 is the image information search table area 43ε1 for media 1 file 1.
-1. ....

Image information search table area 4 for media 1 file n
It is divided into 3Et-n, and other media image information search table areas are similarly divided. The image information search table area for each media file contains search information corresponding to each image information, such as the image information name and the image information storage start address on the optical disk where this image information is stored. It is configured so that it can be stored. For example, the image information search table area 43E1-1 for media 1 file 1 contains image information 1-1-
Image information 1-1-1 name storage area 43 A 1-1-1 that stores the name of image information 1-1-1, and image information 1 that stores the storage start address on the optical disk of image information 1-1-1.
-1-1 Storage start address storage area 43e 1-1-
1,...9 Image information 1-1-n name storage area 43 A t- for storing names of image information 1-1-n
An image information 1-1-n storage start address storage area 43a1-tn is configured to store the storage start address of the image information 1-1-n on the optical disk, and a search table area for other media files. is also divided and configured in the same way.

One side of the optical disk 13, that is, the medium, is composed of a media name storage area 50 that stores the name of the medium, as shown in the memory map shown in FIG. 8, and an image information storage area 51 that sequentially stores image information.

The next difference is the configuration of one of the function implementation means of the CPU 17, and when the password information is input via the operation section 12, the input password information is transferred to the magnetic disk 1.
Image information is stored and searched for the unit of image information corresponding to the password information only when it matches any of the password information group (common secret code for each media, secret code for each file) stored in 5. configured to allow it.

Next, the operation of the second embodiment device is explained in FIGS. 9(a) and 9(b).
) and (C). It is assumed that image information is stored in a suitable medium before the start of the operation, and that the image information has been subjected to seven fillings for information management on the magnetic disk 15 as described above.

First, the media of the optical disc 13 to be used is loaded into the optical disc device 14 (step 5A1), and the media name is read from the optical disc 13 (step SΔ2).
. Then, the file name to be used is input from the operation section (step SAa), and then the secret code is input from the operation section 12 (step 5A4), and the media common secret code of the medium (used medium) is input from the magnetic disk 15. In reading step 5As), it is determined whether the read media common secret code matches the input secret code (stop SAG).

If they do not match, read the file secret code corresponding to the file name input from the operation unit 12 from the magnetic disk 15 (step 5AT), and determine whether the read file secret code matches the input secret code (step 5AT).
Step 5As), if there is a mismatch, display on the CRT display section 26 that the entered secret code is incorrect (
Step SAs).

When it is determined in either step SAs or step SAa that the confidential codes input from the operation unit match, the set of image information corresponding to the confidential code is checked, for example, even if the matched code is a file confidential code. For example, if the corresponding file matches the media common secret code, access to image information will be permitted for all files included in the media used, and the business name specified by the operation unit will be allowed. That is, an operation command is input (step 5A1o). In the case of the apparatus of this embodiment, the operations are broadly divided into registration and search, so it is determined whether the input operation name is registration (step SAs t ).

When it is determined that the image information has been registered, the process moves to the flow shown in FIG.
2), and while inputting the image information to be registered via the two-dimensional scanning device 10, the image length is calculated at the same time (step SAs 2).
a). Then, the next image information storage start address on the optical disk is read from the magnetic disk 15 (step 5A14), and the image information inputted in the above step is started to be written after this next image information storage start address on the optical disk (step 5A14). 5As5). Then, in the image information search table area 43 of the magnetic disk 15 during which image information is stored on the optical disk 13, the area of the medium and file that is the object of development registration processing is searched (step 5A1s). The image information is stored in the head area of the area hollow area, and the storage head address on the optical disk of the image information with this name is then stored (step SAI r ). After completing the filing of image information in this way,
The image length of the current image information is added to the "next image information storage start address" stored in the magnetic disk 15 (step 5A111), and the value of the next image information storage start address storage area 44 is replaced with the value after the above addition. (Step 5A19), the registration process for the image information is completed.

When it is determined that the search is to be performed in step 5A11, the process moves to the flow shown in FIG.
A2 o). Step S of sequentially reading out all the image information names included in the currently accessible files in the image information search table area 43 of the magnetic disk 15.
A2 t ), it is determined whether the read image information name matches the image information name input in step 5A26 (step SA22 ). If they match as a result of this determination, the image information storage start address corresponding to the image information name is read from the magnetic disk 15 (step 5A23), and the image information is read from the optical disk 13 based on this start address (step 5A23). S.A.
2a) Display this on the CR7 display section 26 (step SA2s). Also, if there is no matching image information as a result of the determination in step SA22, CR7 indicates that there is no corresponding image information.
It is displayed on the display section 26 (step SA2s).

As is clear from the above description, in the device of the second embodiment, when it is necessary to access image information within the range of all image information included in one medium, a specific staff member inputs the media common secret code. If you remember one thing, you can access image information within the entire range of one medium, and at the same time, the file security code set for each file allows you to maintain the confidentiality of each file from general staff.

Note that the media common secret code and each file secret code can also be set for each job.

When the secret code is set in this way, as shown in Figure 9 (a)
Immediately after starting step 5A1t shown in or step SA1
It is sufficient if the operation is executed immediately after step SAi or SA2 and thereafter for each task.

Note that the above two embodiments are merely examples, and it goes without saying that various modifications can be made within the scope of the gist of the present invention.

For example, in the first embodiment, the second unit that includes a plurality of first units (for example, files) each having a group of image information of the same nature as one unit includes all of the files, and all image information related to input and output. In other words, all the image information group units (system units) related to the image information input/output system of the device of this embodiment are treated as one unit, and in the second embodiment, a single replaceable information storage medium (e.g. Although it is defined as a monochrome media in which one side of an optical disk or disk is one unit, it is not limited to this. For example, a third unit (e.g., corresponding to the medium described in the second embodiment), which is a single replaceable information storage medium that stores image information (e.g., one side of an optical disk); and a fourth unit (e.g., equivalent to the system unit described in the first embodiment) that includes all of the units and includes all image information groups related to input and output as one unit. be able to. In this case, the third password information set for each third unit (e.g., corresponding to the media common password information group explained in the second embodiment) and the third password information set for the fourth unit are set for each third unit. The second password information can be configured by the fourth password information (for example, the intra-device common secret code described in the first embodiment). When configured in this way, the control means responds to the password information input from the operation unit only when the password information matches any one of the first password information, the third password information, or the fourth password information. It is configured to allow input and output of image information for each unit.

Further, the first unit is not limited to a unit consisting of a group of image information having the same properties, but may be any unit consisting of an individual or a plurality of image information.

Furthermore, the image information input means is not limited to the two-dimensional scanning device, and can be replaced with various devices such as a communication control device that receives image information transmitted from an external device.

Further, the storage means for inputting various password information is not limited to the magnetic disk for managing the filing of image information as in the above embodiment, but may be replaced by any suitable storage medium.

[Effects of the Invention] As detailed above, in the image information storage and retrieval device of the present invention, the first
