Description

The present invention relates to an image processing apparatus communicably connected to a data processing apparatus via a network or a data processing method in the image processing apparatus .

  Conventionally, an operator reads an image with a reading device and registers the read image data in a database server. In general, when an image database is constructed, an image is read by a reading device, a name, a search keyword, etc. are added to the target image and stored in a storage device in a unique format. A device that stores and publishes data and a reading device exist separately, and the read image data is transferred to the server side via SCSI or parallel I / F or through a network.

  The image database is disclosed on the network, and recently, it is also disclosed to clients on the network using WWW (World Wide Web). When using the registered image data, the WWW browser tool is used to search for the image data name, keyword, etc. and display the image.

  On the other hand, when printing an image as necessary, the user of the image selects a printer and sets conditions for printing by the printer.

  However, image data that has been released on the network using the WWW is provided to a device that can be viewed in the form of the image being read, but recent reading devices have high resolution such as 1200 dpi and 600 dpi. However, there is a problem that the data size is large at the resolution as it is, and sending it to the client side causes an increase in network load and transfer time.

  In addition, if the original image is made public, there is a problem that it is arbitrarily modified against the intention of the registrant.

  On the other hand, when printing publicly available image data with a device that can be viewed, although there is a high degree of freedom, all of the selection of printers, setting of printing conditions, etc. must be done on the client side, and printing is troublesome. It was hanging.

  There is also a problem that a desired print result cannot be obtained unless it is set according to the characteristics of the image data.

  In addition, a failure may occur in the selected printer during printing. However, when the failure occurs, the failure must be removed, or another printer must be selected and set again.

Accordingly, the present invention provides a data processing method and an image processing apparatus capable of reducing the size of the data and shortening the transfer time when browsing the image data, and limiting the browsing of the original image and protecting the image. And a storage medium.

In addition, the present invention provides a data processing method, an image processing apparatus, and a storage medium that can reduce the burden on settings when browsing and printing image data from a network and can obtain satisfactory printing results. To do other purposes.

Furthermore, another object of the present invention is to provide a data processing method, an image processing apparatus, and a storage medium that can be output to another printer without bothering the client with respect to a printer failure.

  The reader unit 1 reads an image of a document and outputs image data corresponding to the document image to the printer unit 3 and the file unit 6. The formatter unit 2 develops PDL (Page Description Language) data transferred from a personal computer or workstation via a network into image data that can be printed by the printer unit 3.

  The printer unit 3 prints an image corresponding to the image data from the reader unit 1 and the file unit 6 on a recording sheet.

  The facsimile unit 4 decompresses the compressed image data received via the telephone line 12, transfers the decompressed image data to the core unit 5, compresses the image data transferred from the core unit 5, and compresses the compressed image data. The image data is transmitted via the telephone line 12.

  A storage device capable of recording image data such as a magneto-optical disk drive unit (large capacity disk device) 9 and a hard disk unit (direct access storage device) 10 is connected to the file unit 6, and an image transferred from the core unit 5 is connected to the file unit 6. Record the data.

  The file unit 6 searches the compressed image data stored in the magneto-optical disk based on the keyword transferred via the core unit 5, reads the retrieved compressed image data, decompresses it, and decompresses the image data Is transferred to the core unit 5. An image data file used as an image database is stored in the file unit 6.

  The network interface unit 7 is an interface between the personal computer (PC) or workstation (WS) and the core unit 5 and also a network server, and is configured as a network control center.

  A network interface (network server) unit 7 communicates with a personal computer or workstation on the network, and accepts browsing requests and print requests for image data stored in the file unit 6.

  The operation panel unit 8 is configured as a touch panel type liquid crystal panel, for example, and is connected to the core unit 5. The operation panel unit 8 has a function of controlling the image processing apparatus and displaying the status of the image display apparatus, and is used for inputting attribute information, selecting image data and a printer, and setting printing conditions, which will be described later. .

  In this case, the means for performing various inputs and settings performed via the operation panel unit 8 is not limited to the touch panel type liquid crystal, and may be, for example, a key input unit and a display unit divided.

  FIG. 2 is a block diagram showing a configuration of the core unit 5 of the image processing apparatus. The core unit 5 includes a CPU 21, a ROM 22, a nonvolatile memory 23, an image memory 24, a data processing unit 25, an interface unit 26, and a RAM 27.

  In the core unit 5, the image data from the reader unit 1 is transferred to the data processing unit 25 via the interface unit 26 and is temporarily stored in the image memory 24. Further, a control command from the reader unit 1 is transferred to the CPU 21.

  The CPU 21 controls the operation in the data processing unit 25 in accordance with a control program stored in the ROM 22 or a command transferred from the reader unit 1 or the operation panel unit 8.

  The nonvolatile memory 23 is a part for storing a management file (index file) of data necessary for providing the database function of the image processing apparatus. The image memory 24 temporarily stores image data transferred from the reader unit 1 or the file unit 6 via the interface unit 26. The RAM 27 is used as a work area for the CPU 21.

  The data processing unit 25 is a part that performs image processing such as rotation processing, scaling processing, and resolution conversion on the image data temporarily stored in the image memory 24, and creates a reduced image with resolution conversion. Part. The data processing unit 25 performs image processing based on information set in the operation panel unit 8, and processes the processed image data through the interface unit 26 to the file unit 6, the printer unit 3, the network interface unit 7, and the facsimile unit. 12 for transfer.

  As described above, the image processing apparatus according to the present embodiment has composite functions such as reading of a document image, printing of an image, transmission / reception of an image, storage of an image, and input / output of data from a computer, with the core unit 5 as a center. .

  FIG. 3 is a diagram showing the relationship between the image data file to which the attribute information of the image data is added and the created reduced image. Image attribute information representing attributes such as a title, date, time, user ID, and client display reduced image (resolution designation) is stored in the file unit 6 as one image data file in accordance with the image data.

  The user ID indicates management authority for the registered image, and is used when browsing or deleting the original image from the network. These attributes are unique to the image data. When the title is omitted, the date and time when registration (reading) is performed is used instead of the title. By recording these information in the same file as the original image, even if a plurality of images are recorded, the attribute information is not shifted.

  FIG. 4 is a diagram showing an index file which is a data management file. The index file has a table in which the image title and the location information of the disc that is the storage location are associated with each other. The position information is a numerical representation of the combination of the type of storage device (disk) and the logical address (LBA: Logical Block Address) on the disk.

  FIG. 5 is a diagram showing an attribute setting screen at the time of image registration displayed on the operation panel unit 8. The operation panel unit 8 allows the operator to set the title of the image to be registered, the date and time of registration, the user ID indicating the image management authority, and the resolution for creating the reduced image on the screen. Default values are set even if no input is made except for the user ID. If title input is omitted, the date and time are used instead. The figure shows a case where the resolution of the reduced image is set to 100 dpi. It is also possible to change these default values.

  The operation of the image processing apparatus having the above configuration will be described. FIG. 6 is a flowchart showing an operation processing procedure of the image processing apparatus. This processing program is stored in the ROM 22 in the core unit 5 and is executed by the CPU 21. First, an operation from taking an image from the reader unit 1 to registering it in the database will be described. First, an original is placed on the reader unit 1 and an instruction to start reading an image is given. At this time, the operation panel unit 8 displays a screen for setting attribute information related to image data registration (see FIG. 5).

  When the registrant selects the title displayed on the screen, the user ID, and the resolution for creating the reduced image, and presses the OK button 29 on the screen (step S301), the reader unit 1 reads the image. Start (step S302).

  The resolution of reading is determined by the specifications of the reader unit 1. The read image is temporarily stored in the image memory 24 in the core unit 5. Based on the resolution of the reduced image selected in the core unit 5, the reduced image data of the image stored in the image memory 24 is created by the data processing unit 25 (step S303).

  The created reduced image data is added to other attribute information (title, registration date time, user ID), and the added attribute information is added to the original image data to form an image data file (step S304). Further, the title of the attribute information of the image data file is registered in the index file (step S305) and recorded in the storage device (hard disk unit 10) connected to the file unit 6 (step S306). At this time, the recorded position information is also recorded in the previously registered index file. This completes the process of registering the image.

  If the registrant does not enter anything in the title field, which is a setting item, the date and time of registration is used as the title.

  Next, an operation when browsing image data with a client on the network will be described. FIG. 7 is a flowchart showing an image browsing processing procedure. This processing program is stored in the ROM in the core unit 5 and is executed by the CPU 21. When an access request is made from a client on the network to the apparatus, the core unit 5 is stored in the nonvolatile memory 23 using a mechanism as a WWW server that is a function of the network interface unit (network server unit) 7. An index (INDEX) is generated based on the index file.

  The index (INDEX) is used to present a registered image file to a client on the network, and associates the title of the registered image file with the image data file.

  When the client designates an image from the index (INDEX), the core unit 5 searches for the designated image (step S401). As a result of the search, the presence or absence of designated image data is determined (step S402). If the specified image data does not exist, that is, if the search result is NG, an error message such as “The specified image is not in the current storage device” is transmitted to the client via the network interface unit 7. (Step S408). Since a plurality of storage devices can be attached to the file unit 6, such an error exists.

  On the other hand, if it is determined that there is specified image data as a result of the search, that is, if the search result is OK, the reduced image data is read from the attribute information portion of the associated image data file and transmitted to the client side. (Step S403). At this time, the resolution of the reduced image is also transmitted to the client for display.

  It is determined whether or not the client side has requested the original image (step S404). If the original image has not been requested, the processing is terminated as it is. On the other hand, when the client side requests the original image, the client side requests the user ID of the designated image (step S405).

  The user ID set and transmitted by the client in response to the request is collated with a user ID registered in advance (step S406). If the collation result is correct (OK), the original image is read and transmitted (step S407). The process is terminated. On the other hand, if the user ID set on the client side is invalid (NG), an error message is transmitted (step S408), and the process is terminated.

  As described above, in the image processing apparatus according to the first embodiment, when a browsing request is made from a client, the transfer time is greatly increased by transferring an image with a small data size, which conventionally takes a long transfer time of image data. And a reduction in network load (a reduction in the amount of communication on the communication medium) can be achieved.

  In addition, it is possible to limit the use of a high-resolution image (original image) that is registered and read in the database by publishing only the image with a reduced resolution, and this also leads to protection of the original image. Thereby, modification of the registered original image can be prevented.

[Second Embodiment]
Since the image processing apparatus according to the second embodiment has the same hardware configuration (see FIGS. 1 and 2) as that of the first embodiment, description thereof is omitted.

  FIG. 8 is a diagram showing an image data file to which image data attribute information is added. Image attribute information representing attributes such as title, date and time, user ID, selected printer, printer print setting, and the like are stored in the file unit 6 together with the image data as one image data file. The user ID indicates the management authority for the registered image, and is used when browsing the original image on the network, deleting it, or changing settings at the time of printing.

  In order to enable selection of a plurality of printers, the attribute information includes print setting items for each printer. In the setting items [Printer 1] and [Printer 2], the position, name, and status information on the network are set as information for identifying the printer.

  These attributes are unique to the image data. When the title is omitted, the date and time when registration (reading) is performed are used instead of the title. By recording these information in the same file as the original image, even if a plurality of images are registered, the attribute information is not shifted.

  The index file is the same as that shown in FIG. 4 of the first embodiment, and has a table in which the image title and the location information of the disc as the storage location are associated with each other. The position information is a numerical value representing the combination of the type of storage device (disk) and the logical address (LBA: Logical Block Address) on the disk.

  FIG. 9 is a diagram showing an attribute setting screen at the time of image registration displayed on the operation panel unit 8. The attribute setting screen displays the title of the image to be registered, the date and time of registration, the user ID indicating the image management authority, and the selected printer name.

  When the output destination setting button 31 on the attribute setting screen is pressed, a list of printers that can output is displayed as shown in FIG. FIG. 10 shows an output destination setting screen. It is possible to select a printer by marking a check box 33 on the left side of the printer list. In addition to the printer unit 3 of the present apparatus, printer information that can be output on the network is displayed as outputable printer information.

  The selected printer is reflected in FIG. When the printer is checked, setting information at the time of printing, for example, setting items such as paper size, enlargement / reduction, page layout, printing direction, number of copies, sorting, and duplex are displayed. These differ depending on the function of the selected printer. When the [Return] button 34 at the lower right is pressed, the screen returns to the screen of FIG.

  FIG. 11 is a diagram showing a screen when browsing an image registered in the image database on the client side. The software to be browsed may be different for each client, but here, as information transmitted from the network server unit 7 of this apparatus, image data 40, title 41, registration date 42, and print for instructing printing The button 43 and the information of the selected printer name 44 are transmitted.

  When printing from the browsing software used on the client side, this screen image is output. When the prepared print button 43 is instructed (pressed), only image data is output to a preset printer. That is, the part where the printer name is displayed is designated and output to the printer is performed. When all the displayed printers are selected, output is made to all printers.

  Next, registration processing, image browsing, and printing processing in the image processing apparatus will be described. FIG. 12 is a flowchart showing an operation processing procedure from taking image data from the reader unit 1 to registering it in the image database. This processing program is stored in the ROM 22 in the core unit 5 and is executed by the CPU 21.

  First, an original is placed on the reader unit 1 and an instruction to start reading is given. The resolution of reading is determined by the specifications of the reader unit 1. At this time, the operation panel unit 8 displays a screen (FIG. 9) for setting attribute information related to image data registration. First, the registrant sets the title and user ID displayed on the screen (step S501), determines whether or not the output destination has been set (step S502), and the output destination has been set. When the [OK] button 32 on the screen is pressed, reading of an image is started by the reader unit 1 (step S504).

  On the other hand, if the output destination is not set in step S502, the output destination is set by the registrant (step S503), and the process returns to step S501. That is, when the output destination is not set, the printer selection screen (output destination setting screen) shown in FIG. 10 is displayed to prompt the registrant to set the output destination. As an output destination printer, a printer unit 3 of the present apparatus and a printer available on the network are displayed.

  The image data read in step S504 is temporarily stored in the image memory 24 in the core unit 5. Attribute information (title, registration date / time, user ID) including output destination information is added to the original image data to form an image data file (step S505).

  Further, the title of the attribute information of the image data file is registered in the index file (step S506), and recorded in the storage device (hard disk unit 10) connected to the file unit 6 (step S507). The position information recorded at this time is also recorded in the index file registered earlier. This completes the registration process.

  If the title field as a setting item has not been input by the registrant, the date and time of registration is used as the title.

  Next, a case where image data is browsed from a client will be described. FIG. 13 is a flowchart showing an operation processing procedure when browsing image data from a client on the network. This processing program is stored in the ROM 22 in the core unit 5 and is executed by the CPU 21.

  When an access request is made from a client on the network to the apparatus, the core unit 5 is stored in the nonvolatile memory 23 by using a mechanism as a WWW server that is a function of the network interface unit (network server unit) 7. An index (INDEX) is generated based on the stored index file.

  The index (INDEX) is used to present a registered image file to a client on the network, and associates the title of the registered image file with the image data file.

  When the client designates an image from the index (INDEX), the core unit 5 searches for the designated image (step S601). As a result of the search, it is determined whether there is designated image data (step S602). If there is no specified image data, that is, if the search result is NG, an error message such as “The specified image is not in the current storage device” is transmitted to the client via the network interface unit 7. (Step S606). Since a plurality of storage devices can be attached to the file unit 6, such an error exists.

  On the other hand, if there is image data searched in step S602 as a result of the search, that is, if the search result is OK, the attribute information portion and the image data portion of the associated image data file are read (step S603) and transmitted. Information (display information) is created (step S604), and the display information shown in FIG. 11 is transmitted to the client side (step S605). Thereby, the process is terminated.

  Next, a case where image data is printed from a client will be described. FIG. 14 is a flowchart showing an operation processing procedure for printing image data from a client. First, the printer displayed on the client side is specified. That is, one print output is instructed to the two printers (MPF1, MPF2) displayed in FIG.

  When the [Print] button 43 is pressed, the printer name selected by the client is sent to the apparatus, and the information is received (step S701). The selected printer is recognized, and information on the designated printer is acquired based on the attribute information (step S702). Image data and printer setting information are transmitted to the designated printer (step S703). If the printer unit 3 in the apparatus is designated, data is sent to the printer unit 3.

  It is determined whether or not there is an error in the print output (step S704). If there is no error, an output notification including the output printer name is sent to the client (step S705). On the other hand, if there is an error in the print output, it is determined whether there is another printer that is set to output attribute information (step S707).

  If there is another printer, the process returns to step S702 to start output of the printer. On the other hand, if there is no other printer, the client is notified that the output could not be performed (step S708).

  It is determined whether or not the output of all the printers selected on the client side has been completed (step S706), and if there remains a selected printer that has not been output, in order to start output of the next printer, step S702 is started. Return to the process. On the other hand, if the output of all the printers has been completed, the process is terminated.

  Therefore, when a failure occurs in the set printer, it is possible to start printing of the next set printer. It is also possible to output to a plurality of printers.

  As described above, in the image processing apparatus according to the second embodiment, when the image data from the network is printed, the printing condition of the image data is set in advance by the registrant. Therefore, the image user requests printing. In this case, output can be performed under optimum conditions.

  Furthermore, conventionally, when printing a publicly available image, although the degree of freedom is high, the client side has to set all printing conditions, so it has been time-consuming to print, but when registering image data, a registrant However, setting the printing conditions for the printer will reduce the burden on the user.

  In the second embodiment, reduced image data is not created. However, reduced image data may be created and used for browsing as in the first embodiment.

  Further, the present invention may be applied to a system constituted by a plurality of devices, or may be applied to an apparatus constituted by one device. Needless to say, the present invention can also be applied to a case where the present invention is achieved by supplying a program to a system or apparatus. In this case, the system or apparatus can enjoy the effects of the present invention by reading the storage medium storing the program represented by the software for achieving the present invention into the system or apparatus.
