Abstract

PURPOSE:To accurately detect a required image even from the ambiguous memory of an operator by recording the contents and date/time of an operation executed before as the keyword without adding a keyword to an input image with a special operation. CONSTITUTION:The date/time to be retrieved and the number of sheets of image are inputted from a keyboard 203. A CPU 202 operates an ID retrieving/ display means 209 to read the contents of retrieval information from an optical disk storage device 207, executes the collation of whether the contents above are matched with a user ID used at the time of log-on by the operator or not and lists up the matched contents. Next, the contents matched with the designated date are retrieved from among contents listed up by the ID retrieving/display means 209 by using a date retrieving/display means 210. Further, the contents matched with the designated number of sheets of image are retrieved from among contents listed up by the date retrieving/display means 210 by using a page retrieving/display means 212. When the matched contents is retrieved, they are outputted to a display device 204 and a printer 206.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image file system, such as an image file device, which stores a large amount of images and retrieves the images. The present invention relates to an image file system that employs an image file search method in which an image is searched from an ambiguous memory that has been viewed and then displayed or printed.

[0002]

2. Description of the Related Art In recent years, due to improvements in computer processing capability and the advent of large-capacity memories, there has been an increase in the number of jobs for accumulating a large amount of data in a database and using the accumulated data later. In general, keywords that represent the characteristics of data are often added to data stored in a database at the time of data input so that they can be easily searched later. In addition, when the input data is a character code, the input data itself can be used as data for searching, and thus it may not be necessary to add a special keyword. For example, since numerical values such as date and time and price in the input data can be represented by a character code, they can be used as keywords themselves.

On the other hand, due to the recent improvement in computer processing capability, not only character codes but also image data have increased as input data. Since the image data can be input from the scanner device like a copy, it is not necessary to be accustomed to keyboard operation unlike character code input, and can be used by anyone. However, even in an image in which characters are written, the written characters are only a collection of color data, and it is difficult to use them as search data instead of keywords like character codes. Therefore, in the early electronic file devices and the like, it was necessary to add a keyword to the image data without fail.

In the electronic file device, various search means have been provided in response to a request from a user that adding a keyword is troublesome. For example, "Hitfile 6500" manufactured by Hitachi, Ltd. has a function of automatically setting a clock in an electronic file device and automatically setting an image input date and time as a keyword.
, And many electronic file devices are supported. This function may be specified by the operator by remembering the input date and time accurately, or the operator's memory is ambiguous and the approximate range is, for example, the second week of November, that is, 7th to 13th. May be specified. This function is described in detail, for example, on pages 5-34 to 5-36 of the above-mentioned "Hitfile 6500" operation manual.

[0005] In addition, there are some which can be searched using the date and time of the previous search as a keyword. In other words, this is a function that is effective when the operator wants to see the image that he / she saw again at that time, and reserves only a storage space for the search date and time at the time of data input, and saves that storage space for each search. Update the date and time. Regarding such a device, there is a system disclosed in, for example, Japanese Patent Laid-Open No. 2-37466. Further, in the system disclosed in Japanese Patent Laid-Open No. 2-37466, it is assumed that a plurality of operators search for the same image, and by linking the operator-specific code information and the search date / time information. , It is also considered to be able to search for each operator.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Even if a special keyword is not added to the image data, the required image can be searched from the ambiguous memory about the operation of the operator, and the complexity of the operation can be reduced. However, not all operations by the operator are recorded as keywords, so
There is a problem that the required search result may not be obtained accurately due to lack of keyword information. For example, the operations of the image database include various operations such as addition and partial deletion of data, as well as display and printing at the time of data input and search, and the distinction between these operations is also important information. Particularly, in the example of Japanese Patent Laid-Open No. 2-37466, it is described that the date and time is recorded only for the search at the time of printing and the date and time is not recorded for the search for the display.
We are also considering recording the date and time of both printing and display, but since there is no means to record the contents of the operation fundamentally,
The operator's memory of what they saw on the display at that time, or when they printed it and handed it to someone could not be searched accurately.

Further, in the normal image data, since a plurality of images are managed as a group of data, it is also important information as to which image in the group of image data is operated. Become. For a group of image data, it is sometimes desirable to use the number of images as a search keyword. For example, it may be desired to search even with an ambiguous memory, such as when there were about ten materials when searched and displayed previously. Also, if there is an image that has been modified or added after being viewed from among the images that were once searched and viewed, it may be necessary to search to obtain the latest information. In response to such a search request, the above-mentioned conventional technique requires many operations.

In addition, as a special use of the retrieval, there is a case where the operator who wants to retrieve and print the confidential or prohibited copy image is searched and known from the viewpoint of security. If printing is prohibited but viewing is allowed, this search takes a lot of time unless the display and the printing cannot be distinguished. On the contrary, it may be desired to search a specific image for the purpose of confirming whether the operator who has to search and see the image really sees it. This process also requires a search operation and information for identifying the operator. Further, in order to statistically grasp the usage status by the image search, it is sometimes desired to search and know the searched operator or the content of the operation itself. Realization of such processing is difficult with the above-described conventional technology.

An object of the present invention is to record many of the operations previously performed as keywords without adding the keywords to the input image by a special operation.
It is to be able to accurately retrieve the required image even from the vague memory of the operator. Further, it is to identify the operator who performed a certain operation by storing the operation performed before.

[0010]

In order to achieve the above object, in an image file system according to the present invention, identification information for identifying an operator, content of operation of each operator, and operation thereof are provided for each image data unit. The date and time when the operation was performed, the means for storing the page number of the image that was the target of the operation, the means for inputting the keyword for the search, and the keyword by collating some or all of the stored information Means for displaying the retrieved image, a means for displaying or printing the retrieved image to the operator, a means for extracting information not used as a keyword of the retrieved image, and a means for displaying or printing the retrieved information for the operator. ,use.

Further, as identification information for identifying the operator,
Use a means to record the ID you enter when you log on to the system. And when the operator searches for images,
Even if there is no special instruction from the operator, a means for using the logon ID of the operator as one of the search keywords is used.

Further, a means for counting the number of images to be operated from the page number of the image to be operated is used. Further, even if the operator does not input the search keyword, the means for setting the content of the operation of the keyword to print is used.

[0013]

When inputting an image, the identification information for identifying the operator and the content of the operation by each operator are set for each image data unit.
By means of storing the date and time when the operation was performed and the page number of the image that was the target of the operation, the logon ID of the operator, the content of the operation, the date and time of the operation, and the page number that was the target of the operation as search information. Is recorded so that the corresponding image can be displayed or printed when these pieces of search information match all search items specified at the time of search.

The case of searching for an image is as follows. When the operation to be searched is specified by one of display, print, add, and delete, or a combination of them, the operator's logon ID is the keyword for the search, even if there is no special instruction from the operator. First, the search target is narrowed down to the one operated by the operator in the past. Next, by means of inputting search keywords,
Enter the keyword of the image required by the operator. The input keyword is used to collate the keyword with a part or all of the stored information, and the image is searched by an image searching unit. Further, the result is shown to the operator by means of displaying or printing the retrieved image to the operator. When searching by the number of images, the number of images to be searched is input by means of inputting a search keyword. Also, if there is another keyword, the same keyword input means for search is used. Then, first, with respect to keywords other than the number of images, the keywords are collated with a part or all of the above stored information,
The target of the search is narrowed down by the means for searching the image. With respect to the narrowed-down images, the number of images to be operated is calculated by the means for counting the number of images to be operated from the page number of the image to be operated. And
By using only the number of images as a keyword, the keyword is collated with a part or all of the stored information, and an image is searched by an image searching unit.

When an image is searched for a special purpose, it is as follows. In this case, when the operator searches for an image, even if there is no special instruction from the operator, the above-mentioned means for making the operator's logon ID one of the search keywords is not used, that is, the operator does not The keyword is input by the means for inputting the keyword for search without narrowing down the search target images. When checking whether there is an operator who printed an image whose printing is prohibited, set the keyword by means of setting the content of the keyword operation to print, and enter the keyword for some or all of the stored information. And the printed image is searched by the image searching means. Next, the means for retrieving the information not used as the keyword of the retrieved image retrieves the logon ID of the printed operator and displays or retrieves the retrieved information to the operator and displays the retrieved image for the operator. Or by means of printing,
The logon ID of the operator and the image are output. From these two types of output information, the operator who printed the image whose printing is prohibited can be known. In the case of statistically grasping the use situation by image retrieval, for example, the date and time for which the use situation is desired to be grasped is inputted by means of inputting a keyword for retrieval. The keyword is collated with a part or all of the stored information, and the image operated by the image search means is searched for the image operated. A means for extracting the logon ID of the operator who performed the operation, the content of the operation and the page number of the operation target by means of extracting the information not used as the keyword of the searched image, and displaying or printing the extracted information to the operator. By the means for displaying or printing the retrieved image to the operator, all information of the image and its operation is output. The usage status can be grasped from this output information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to an illustrated embodiment.

FIG. 1 is an explanatory diagram showing a storage hierarchical structure of a file system according to one embodiment of the present invention, FIG. 2 is a configuration diagram of the file system according to this embodiment, and FIG. 3 is a display date and time in this embodiment. It is explanatory drawing which shows an example of a search display screen.

The storage structure shown in FIG. 1 has three layers. The top layer is the cabinet 101, the second layer is the file 102,
The third layer is the document 103. These layers are for managing the image data, and the actual image data 104
Are located below the document 103. Cabinet 10
1, file 102, document 103, image data 104
Is a general management structure of electronic file device,
It is used in electronic file device products of each company including "Hitfile" of Hitachi, Ltd.

When searching for the necessary image data 104 in the file system having the storage structure as shown in FIG.
After the operator designates the cabinet 101 and the file 102, a plurality of documents 103 managed by the file 102 are searched using a keyword corresponding to the document. The information of the document 103 corresponding to the keyword at this time identifies the document 103, and is called a document name. A plurality of image data 104 is managed under one document 103, but a search by a keyword (document name) corresponding to the document can only identify the document 103, and the image data 104 in one document 103 can be identified. In order to specify, it is necessary to display the image data 104 one by one or specify a page number. This is done for documents of the same type 10
This is because 3 is put together in one file. In other words, for example, as materials related to semiconductor sales by the sales department,
The name of the cabinet 101 is "semiconductor", the name of the file 102 is "minutes", "quote", "slip", "customer information", etc. This is because it is sufficient to search the attached file 102. However, even if the same semiconductor has the same price for each customer, the quote may serve as customer information. For this reason, there are cases in which multiple files or multiple cabinets are collectively searched.

In this embodiment, the search information 10 is stored in the document 103.
5, search information 105 is an area for storing data to be matched with a keyword at the time of search. This search information 105 includes an item 106 for recording the operator, an item 107 for recording the content of the operation, an item 108 for recording the date and time when the operation was performed, and an item 109 for recording the page number of the operation target. It consists of and. For example,
The first piece of the search information 105 shown in FIG. 1 indicates that the operator with the user ID “yamada” has input (registered) pages 1, 2, 3, and 4 on January 11, 1993. There is.

The file system shown in FIG. 2 is composed of a file device 201 which is a server as a whole, a personal computer 215 and a workstation 216 which are clients, and a network 214 which connects the server and the client to each other.

First, the internal structure of the file device 201 will be described. The CPU 202 is a processor that controls the entire file device 201, and advances processing while controlling each device in the file device 201 according to the programs and data stored in the memory 208.

The keyboard 203 is for transmitting an operator's instruction to the file device 201, and is used here mainly for inputting a keyword. Further, as will be described later, when searching only from the personal computer 215 or the like, the keyboard 203 becomes unnecessary. As the keyboard 203, not only a device such as a typewriter in which keys corresponding to characters are arranged, but also an input instruction device such as a mouse or a trackball can be considered.

The display device 204 is a device for showing the searched image and the searched information to the operator. This display device 2
Similarly to the keyboard 203, 04 is unnecessary when displaying on the personal computer 215 side or the workstation 216 side.

The scanner device 205 is a device for converting a document or the like written on paper into electric image data. The image data input from the scanner device 205 is stored in the memory 208.
After being temporarily stored in the optical disk, a large amount is stored in the optical disk storage device 207. Since the image data has a large data amount of 500 kilobytes or more even in A4 size, the data amount may be compressed.

The printing device 206 is a device for outputting the retrieved image and the retrieved information to a sheet of paper and showing it to an operator or the like.
Like the display device 204, the printing device 206 also has a personal computer 215 side and a workstation 216.
It becomes unnecessary when printing on the side.

The optical disk storage device 207 is a device for accumulating a large amount of image data input from the scanner device 205 and information necessary for retrieval. Most of the electronic file devices currently on the market use an optical disk as a storage medium because of cost and access speed. However, a magnetic disk storage device or a magnetic tape storage device will not hinder the realization of the present invention.

The memory 208 is a semiconductor memory device that stores programs and data used by the CPU 202 and image data input from the scanner device 205. The memory 208 has a smaller storage capacity than the optical disk storage device 207, but has a faster access speed for reading and writing data. A part of the program of the CPU 202 stored in the memory 208 includes ID search / display means 209, date / time search / display means 210, operation search / display means 211, page search /
There is a display means 212 and these means 209-212.
Is the above-mentioned items 106, 107, 1 of the search information 105.
This is a program for executing search and display for each of 08 and 109. Details of these means 209 to 212 will be described in the description of each search operation described later.

The network interface 213 is used by the personal computer 2 via the network 214.
15 is an input / output device for communicating with the workstation 216. There are various protocols and specifications in the world, but in the present invention, if communication with other devices is possible,
Either may be adopted.

The personal computer 215 and the workstation 216 are devices which are not shown or which are equipped with at least an input instruction device such as a keyboard and a display device or a printing device. Keyboard 203 and display device 20 in device 201
4, it can be used as an alternative to the printing device 206.

FIG. 3 shows an image previously displayed by the operator.
It is a figure which shows an example of the display screen on the display apparatus 204 at the time of searching with a date and time (here, year, month, day) as a keyword. As is known here, prior to the search, in a computer system that is widely used at present, an operator performs an operation of logging on in order to use the computer. In this operation, the user ID and password that are registered in the system in advance and are not the same in the system are input. The user ID at this time is the memory 2
It is stored in 08.

Next, the operator first uses the keyboard 203 to input "display" as an operation to be searched, and then remembers that the operator has previously viewed and viewed from the calendar. Day (year, month, day) ". As a method of designating the date, a method of inputting a number from the keyboard 203 or using a pointing device such as a mouse and clicking a button according to the date on which the cursor is designated is adopted. Here, in the example of FIG. 3, January 1, 1993
The case where one day is designated is shown.

In response to such an operation, the CPU 202
First, the ID search / display means 209 is read from the memory 208 as a program and executed. ID search /
The display unit 209 reads the content of the item 106 of the search information 105 from the optical disk storage device 207,
Collation is performed to see if it matches the user ID used when the operator logged on. Then, all matching items are listed.

Next, the CPU 202 uses the date / time search / display means 210 to search only those listed by the ID search / display means 209 for ones matching the designated date. That is, the item 1 of the search information 105
While reading the contents of 08 from the optical disk storage device 207, the collation with January 11, 1993 is performed. Further, the CPU 202 uses the operation search / display unit 211 to search only the items listed by the date / time search / display unit 210 for items that match the display of the specified operation. That is, while reading the contents of the item 107 of the search information 105 from the optical disk storage device 207,
Check with the display.

In the example of the search information 105 shown in FIG. 1, the first date and time match, but "registration" is not listed in the operation collation, so there is no corresponding information. All the documents in the file 102 are collated, and if there is a match, a list of document names is displayed as shown in FIG. 3, for example. Further, although not specified in the memory 208, the image data retrieved as a function that an electronic file device normally has is output to the display device 204,
The CPU 202 has a function of outputting to the printing device 206.
Displays or prints out image data according to an instruction from an operator or automatically.

As described above, according to the search method based on the date and time of the display as described above, a necessary image is searched for and displayed only by storing the operation content of the operator and the operation date and time. , Can be printed.
In particular, since the operation content can be specified, the date and time match, but an image of another operation will not be erroneously retrieved. In addition, an image operated by another operator will not be erroneously retrieved.

Next, an example will be described in which an operator searches for an image that has been previously operated by using the date and time (here, year, month, day) and the number of images as keywords. In this case, the operator uses the keyboard 203 and sets the date and time to be searched, for example, from January 6, 1993 to January 18, 1993.
Enter the day, and then set the number of images, for example, 7 to 1
Enter 0 sheets.

In response to such an operation, the CPU 202 first executes the ID search / display means 209 to read the contents of the item 106 of the search information 105 from the optical disk storage device 207 while the operator operates the same as before. Whether or not the user ID used when logging on is matched is checked, and all the matched IDs are listed. next,
Using the date / time search / display means 210, the CPU 202 searches only those listed by the ID search / display means 209 for ones matching the designated date. That is, while reading the contents of the item 108 of the search information 105 from the optical disk storage device 207,
Collation will be performed from the 6th of the month to the 18th of January 1993. Further, the CPU 202 uses the page search / display unit 212 to search only the items listed by the date / time search / display unit 210 for the items matching the designated number.
That is, the content of the item 109 of the search information 105 is
While reading from the optical disk storage device 207, the number of images to be operated is counted from the page number of the image to be operated and collated with 7 to 10.

If there is a final match, the list of document names is displayed, the image data is output to the display device 204, or the printing device 206 is output.

By doing so, it is possible to retrieve a required image, display it, and print it, only by storing the rough number of images and the operation date and time of the operator. In addition, an image operated by another operator will not be erroneously retrieved.

FIG. 4 is an example in which a list of all information is displayed for the retrieved document. In the above-mentioned example, it is explained that the image is displayed or printed after the document name list shown in FIG. 3 is displayed, but in this embodiment, more detailed search information of each document can be known. . In other words, if you want to know more detailed search information for each searched document,
By instructing the CPU 202 to that effect, the user ID is displayed using the ID search / display means 209 in the memory 208, the date and time is displayed using the date / time search / display means 210, and the operation search / display is performed. By displaying the operation content using the means 211 and displaying the page number using the page search / display means 212, a display screen as shown in FIG. 4 can be obtained on the display device 204. ing.

Also, in the case of statistically grasping the usage situation for a specific document, the document name is entered from the keyboard 203 and the function normally provided in the electronic file device, although not specified in the memory 208. There is a document name search function as
3 is searched, and each of the means 209, 21 is searched in the same manner as above.
By using 0, 211, and 212, the search information of the searched document can be output as a history. It should be noted that the output is subjected to statistical processing, although detailed description is omitted because it is not directly related to the present invention.

By doing so, since the history information of the retrieved document can be output by a simple operation, it is possible to easily obtain the data for grasping the usage status of each document.

FIG. 5 and FIG. 6 are examples of a list display of user IDs that have previously performed printing operations and a document name list display of printed documents. By getting such a display,
It is possible to know whether a document whose printing is prohibited due to prohibition of copying or confidentiality has been printed and who is the operator who printed the document.

As shown in FIG. 5, in order to obtain a list display of user IDs printed on one document 103, the following processing is carried out. First, the operator uses the keyboard 203 to input the document name to be searched. In this case, not only the image data operated by the operator who is currently operating but also all the operators are searched,
Do not use the user ID at the time of logon (do not narrow down the search target by the user ID input at the time of logon operation). Therefore, the process by the ID search / display unit 209 of the memory 208 is not executed initially. Memory 208
Although not specifically described therein, there is a document name search function as a function that an electronic file device normally has, and the document 103 is searched from the input document name using this function.

Next, the operator uses the keyboard 203 to input "print" as an operation to be searched. In response to a print operation search instruction, the CPU 202 reads the operation search / display unit 211 as a program from the memory 208 and causes it to be executed. Operation search / display means 211
Reads the content of the item 107 of the search information 105 of the retrieved relevant document 103 from the optical disk storage device 207, and checks whether the content of the operation is “print”. Then, all matching items are listed. Next, the CPU 202 uses the ID search / display means 209 in the memory 208 to display the user ID, the date / time search / display means 210 to display the date and time, and the operation search / display means 211. The operation contents are displayed by using the page search / display means 212, and the page number is displayed by using the page search / display means 212 to obtain a display as shown in FIG.

Since all the operation contents here are "print", the display of the operation contents may not be displayed by the operation search / display unit 211. Furthermore, the operation search / display unit 211 is not limited to one document 103 and can be used for searching a plurality of documents.
Is simply applied to the search information of each document to be searched.

Further, as shown in FIG. 6, one file 102
On the other hand, in order to obtain the list display of the printed document name and the user ID, the following processing is performed. First, the operator uses the keyboard 203 to input the file name to be searched. Also in this case, the user ID at the time of logon is not used because the search is performed not only on the image data operated in the past by the operator who is currently operating but also in all the operators. The search target is not narrowed down by ID). Therefore, memory 2
The processing by the ID search / display means 209 of 08 is not executed initially. Although not specified in the memory 208, there is a file name search function which is a function that an electronic file device normally has, and the file 102 is searched from the input file name using this function.

Next, the operator uses the keyboard 203 to input "print" as the operation to be searched. In response to the print operation search instruction, the CPU 202 causes the file 10
While selecting each document 103 from 2, the operation search / display unit 211 is read from the memory 208 as a program,
Let me do this. The operation search / display unit 211 reads out the content of the item 107 of the search information 105 of the first document 103 from the optical disk storage device 207 and checks whether the operation content is “print”. Then, all matching items are listed. Next, CP
U202 is the next document 10 from the corresponding file 102.
3 is selected and the same processing is executed by the operation search / display means 211. Then, after the processing by the operation search / display unit 211 is executed for all the documents 103 of the file 102 (a list of all the documents 103 of the corresponding file 102 whose operation content is “print” is listed. After that, the CPU 202 determines that the I
By displaying the user ID using the D search / display means 209 and displaying the date and time using the date / time search / display means 210, a display as shown in FIG. 6 is obtained.

Further, when searching for a plurality of files without limiting to one file 102,
The operation search / display unit 211 is simply applied to the search information of all the documents in each file to be searched.

By doing so, the printed image and the operator who performed the printing operation can be displayed by a simple operation.
It will be very useful for managing security.

FIG. 7 is an example of a document list display for correction such as addition or deletion of image pages. Here, an additional example is particularly shown, but the same applies to deletion. For example, even if a document is searched once and viewed, it is often necessary to review the document again when a page is added or deleted after the document is viewed.

As shown in FIG. 7, one file 102
In order to obtain a list display of the document names corrected for, the following processing is performed. First, the operator operates the keyboard 203
Use to enter the file name to search. Memory 2
Although not specifically described in 08, there is a file name search function as a function that an electronic file device normally has.
To search.

Next, the operator uses the keyboard 203 to input "add" as the operation to be searched. In response to a search instruction for an additional operation, the CPU 202 first reads the ID search / display unit 209 as a program from the memory 208 and executes it. ID search / display means 20
9, the content of the item 106 of the search information 105 in each document 103 in the corresponding file 102 is read from the optical disk storage device 207, and whether or not it matches with the user ID used when the operator logs on is verified. To do. Then, all matching items are listed.

After that, the CPU 202 uses the operation search / display means 211 to execute the search only from those listed by the ID search / display means 209. That is, the operation search / display unit 211 reads the content of the item 107 of the search information 105 in the first document 103 listed by the ID search / display unit 209 from the optical disc storage device 207, and the operation content is “added”. Is checked. Then, the matched ones are listed. Next, the CPU 202 selects the next document 103 listed by the ID search / display unit 209 from the file 102, and the operation search / display unit 211.
To execute the same process. And file 1
After all the documents 103 listed by the ID search / display means 209 in 02 are processed by the operation search / display means 211, the documents 103 listed by the operation search / display means 211 are CPU2
02 causes the date / time search / display unit 210 and the page search / display unit 212 to execute processing to display the listed document name, date and time, and page number, so that the display shown in FIG. 7 is obtained. Has become.

When searching a plurality of files without limiting to one file 102, I
D search / display means 209 and operation search / display means 21
Only 1 is applied to the search information of all documents in each file to be searched.

By doing so, since the added document can be known by a simple operation, the latest information can always be obtained.

In the above example, the system starts the search operation when the operator inputs the search keyword. However, by simply instructing the image search after the logon operation, The system may be configured to automatically perform the search operation using print operations, or add or delete operations, as search keywords.

[0059]

As described above, according to the present invention, in a file system in which a large amount of images are stored, if the image is previously operated by the operator, even if the operation memory is ambiguous, the number of operations is appropriately small. Images can be searched by operation.
Also, since the history of operations on images can be managed, it is useful for grasping the usage status and security management.
