Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing system used in an environment in which, for example, a digital copying machine that performs image reading and image formation and a plurality of personal computers are connected via a network.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in an image processing system that performs processing such as reading a document using a scanner connected to a network, an automatic paper feeder such as a digital copying machine shared by a plurality of users connected to the network is used. By using a high-speed scanner, it is possible to perform image reading in document units at once and at high speed.
[0003]
For a user who wants to input a document image from a digital copying machine constituting such an image processing system, a method of handling a plurality of originals in units of documents and instructing scanning (image reading) is as convenient as a copying operation. It is.
[0004]
On the other hand, a low-speed scanner as an image reading apparatus directly connected to a personal computer (PC) has a trial scan function called prescan, which is used for fine adjustment of document size, resolution, density, color, and the like. . In this case, scanning is repeated for each page as instructed from the PC.
[0005]
However, as described above, when scanning a document by document using a digital copier connected to a network,
-There was no effective means for confirming on the spot an image scanned in units of documents by a user performing a scanning operation with a digital copying machine. Further, there is no effective means for confirming on the spot the rescanned image according to the user's instruction. In general, a display screen provided with a digital copying machine is not of a display size suitable for displaying a scanned image, and it is difficult to confirm the scanned image on this display screen. For this reason, it is necessary to confirm the scan image by displaying it on the client PC connected to the network, and the user performing the scanning operation with the digital copying machine needs to return to the client PC and confirm the scan image. was there.
[0006]
・ If there is an unsatisfactory page in the scanned image in the document unit and it is necessary to rescan, the user will revisit the location of the digital copier and rescan all pages in the document unit. Or, it was necessary to take out a page that needs to be rescanned and rescan it in units of pages.
[0007]
-When rescanning is necessary, if the number of pages that need to be rescanned is sufficiently small compared to the total number of pages in the document, discarding all previously scanned images and rescanning and replacing all pages will waste time. It takes a lot of processing time.
[0008]
Since the scanning function of the digital copying machine can operate at high speed, it is effective to handle the document in units of documents in terms of processing time and user operation, and a method of using scanning repeatedly in units of pages is not suitable in the first place.
[0009]
There is a problem.
[0010]
[Problems to be solved by the invention]
As described above, when a document image consisting of a plurality of pages is read in an image processing system using a device connected to a network and shared by a plurality of users, the read image is confirmed on the spot when the reading operation is executed. In addition, it solves the problem that the part that the user wants to confirm is difficult to understand. When reading a document image consisting of multiple pages, the scanned image can be confirmed on the spot when the scanning operation is performed. An object of the present invention is to provide an image processing system that makes it easy to understand a portion of an image that a user wants to confirm.
[0011]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
FIG. 1 is a diagram showing an example of a use environment of an image processing system according to an embodiment of the present invention.
[0018]
As shown in FIG. 1, this image reading system has, for example, a high-speed image reading function, a digital copying machine 2 shared by a plurality of users, a file server 3 storing various data, and each user. Are used in an environment in which a plurality of client PCs 4 such as personal computers that can be used individually are connected to each other via a communication line 5.
[0019]
FIG. 2 is a block diagram showing the configuration of the image reading system 1 used in the above environment.
[0020]
The image reading system 1 includes an image reading unit (reading unit) 11 having an automatic paper feeding unit (ADF) 11a as a document feeding unit that feeds a document unit document D composed of a plurality of documents one by one. An image storage unit (storage unit) 12 for storing an image read by the image reading unit 11, a display input unit (instruction unit) having a touch panel for displaying operation guidance to the user and inputting various instructions by the user. , Notification means) 13, a plurality of read images are reduced and combined, or an image reduction / combination unit 14 that cuts out and combines predetermined portions, and an image read by the image reading unit 11 or an image reduction / combination unit 14 A printing unit (printing means) 15 that prints the printed image on a printing paper P as an image forming medium and a communication line 5 are connected to each device on the network. A communication unit 17 for performing the reading, and a re-execution management table (storage unit) 16a for managing the read image and the re-read image, and a control unit (determination unit, processing unit) 16 for controlling each unit. It is configured.
[0021]
The image reading unit 11 is provided with an automatic document feeder (ADF) 11a. By placing a document unit document composed of a plurality of pages on the document table of the ADF 11a, the document of a plurality of pages is sequentially fed one by one and automatically read.
[0022]
The display input unit uses an operation panel composed of a display unit with a built-in touch panel and hard keys such as a numeric keypad. Instructions for various operations and settings are input through the touch panel and hard keys, and operations are performed on the display unit. Information on the contents of errors and errors at the time of errors is displayed.
[0023]
The image reduction / combination unit 14 performs processing such as image reduction, clipping, and composition in order to print the image read by the image reading unit 11 in a print format designated by the user. Generate a print image.
[0024]
The printing unit 15 prints the image read by the image reading unit on the printing paper as it is, or prints the read image synthesized based on the printing format designated by the user.
[0025]
Each component of the image reading system 1 configured as described above includes the image reading unit 11 and the image printing unit 15 provided as one device by the digital copying machine 2, or the image reading unit 11 and the image printing unit. When the unit 15 is provided as a different device, it may be provided in any device on the network on the condition that the installation locations of both are close.
[0026]
For example, all the components constituting the image reading system 1 may be mounted on one digital copying machine 2 such as the image reading unit 11, or only the image composition unit 14 may be included in the file server 3. The image storage unit 12 and the image composition unit 14 may be installed in the file server 3.
[0027]
Also, instead of a digital copying machine, an image reading device (scanner) having an image reading unit 11 and an image printing device (printer) having an image printing unit 15 are provided by different devices on condition that both are installed at close locations. And may be connected to a network.
[0028]
In the image reading system 1 used in the above environment, an image read by the image reading unit 11 is taken out from the image storage unit 12 and finally connected via a communication unit 17 via a network. By transmitting to the client PC 4 side, a read image is provided to each user.
[0029]
In addition, a user who uses the image reading system 1 in the environment as described above takes the document D to the front of the digital copying machine 2 and instructs to read the document D and executes it. Then, the read image is confirmed on the spot according to the print results printed in various print formats described later, and a page to be re-read is designated.
[0030]
As a result, the user who once brought the document in front of the digital copying machine can reliably complete the image reading operation including confirmation of the read image on the spot, and depending on the image reading state, It is possible to avoid going back and forth between the digital copying machine and the client PC.
[0031]
Next, a print format for printing a read image to confirm an image read by the user will be described in detail with reference to FIGS. 3 (a) to 3 (c) and FIGS. 4 (a) to 4 (d). .
[0032]
The print format for confirming the read image is a full-size copy format in which the read image is printed on one printing paper P per page, and the read image is reduced to the entire page for each page and 1 for each predetermined number of pages. Reduced composite format for printing on a single sheet of print paper P, central cutout composite format for printing on a single print paper P every predetermined number of pages, with the central portion uniformly cut out for all read pages, all read pages For each of the read pages, the lower central portion is cut out uniformly and printed on one printing paper P. For all the read pages, the upper portion is cut out uniformly and printed on one printing paper P for every predetermined number of pages. It is selected from the top cutout composite format.
[0033]
The full-size copy format is a format in which a plurality of pages of original images read are printed at the same size on a printing paper having the same size as the original.
[0034]
For example, the reduced composition format reduces each page by a factor of 1/4 to a read image of a plurality of pages, and reduces each page by 1 (4 in 1) and each page by a factor of 1/9. This is a format for printing an image composed of 9 pages for 1 page, each page reduced to 1/16 times, and 16 pages for 1 page.
[0035]
The above-mentioned center cutout composition format is, for example, to extract a quarter of the read image centered on the center portion of each page from a read document image of a plurality of pages, one sheet for four pages, the center of each page Extract 1/9 of the scanned image centered at the center and extract 1 page for 9 pages, or extract 1/16 of the scanned image centered on the center of each page and combine 16 pages into 1 sheet A format for printing images.
[0036]
The lower cutout composition format is, for example, for a scanned document image of a plurality of pages, which is extracted by ¼ of the read image centered at the lower center of each page, and one page for each four pages. Extract 1/9 of the scanned image centered at the lower center and 1 sheet of 9 pages, or 1/16 of the scanned image centered at the lower center of each page and extract 1 page 16 This format prints images that are combined on a sheet.
[0037]
In the upper cutout composition format, for example, from the read document image of a plurality of pages, the upper part of each page is extracted by 1/4 to extract one page for 4 pages, and the upper part of each page is extracted by 1/9 to 9 In this format, one page is extracted, or the upper part of each page is extracted by 1/16, and an image obtained by combining 16 pages into one is printed.
[0038]
FIGS. 4A to 4D are diagrams showing specific examples of print formats for confirming read images when the originals shown in FIGS. 3A to 3C are read. Here, as shown in FIGS. 3A to 3C, a description will be given of a case where a document composed of three pages of document D is read.
[0039]
That is, when the user selects the full-size copy format, the digital copying machine 2 performs printing for all pages by assigning page numbers to the read image at the same size as the read image.
[0040]
When the user selects the reduction composition format, the digital copying machine 2 reduces the entire page to 1/4 by the reduction composition unit 14 as shown in FIG. A composite image in which a page number is assigned to each read image by pasting in order is generated, and printed on the printing paper P by the printing unit 15.
[0041]
When the user selects the center cutout composition format, as shown in FIG. 4 (b), the digital copying machine 2 cuts out only the central 1/4 portion of each page and cuts the upper left, upper right, and lower left. A composite image in which the page number is assigned to each read image is generated in order of the above, and is printed on the printing paper P by the printing unit 15.
[0042]
When the user selects the lower cutout composition format, as shown in FIG. 4C, the digital copying machine 2 uniformly cuts the lower center part of each page by 1/4 of the original image, A composite image in which page numbers are assigned to each read image is generated in the order of upper right and lower left, and is printed on the printing paper P by the printing unit 15.
[0043]
When the user selects the upper cutout composition format, as shown in FIG. 4D, the digital copying machine 2 cuts out the upper 1/4 portion of each page and arranges them in order from the top. Then, a composite image in which a page number is assigned to each read image is generated, and is printed on the printing paper P by the printing unit 15.
[0044]
As described above, a document composed of a plurality of pages of a document is read and printed from various printing formats as described above in order to confirm on the spot whether the client PC 4 has read an image that can be used without any problem by the user. When a read image is printed out by selecting a format, each print format is effective in the following points.
[0045]
In other words, depending on the purpose that the user wants to confirm,
The full-size copy format that prints and outputs all pages as a single page at the original size is effective when it is necessary to check all the details such as resolution, document feed, density, and bending.
[0046]
-Reduced composite format that reduces all pages and prints them out in 4 pages per sheet, 9 pages per page, 16 pages per page, etc., confirms that the entire document has been read without missing pages or bent pages It is effective.
[0047]
・ All the pages are uniformly extracted from the center by 1/4, 1 for 4 pages, 1/9 for 9 pages, or 1/16 for 16 pages for 1 page. In the center composition format, which prints out side by side, there is generally meaningful image information at the center of the document, and there is a high probability that it is not a blank area. It is effective to do.
[0048]
-The lower composite format that prints out all the pages uniformly by cutting out the lower center part and arranging multiple pages on one sheet, if the page number is assigned to the lower center part of the document, tracks that page number. This is effective for easily confirming whether or not there is a missing page due to an error in document feeding.
[0049]
・ The upper composite format, which cuts out the upper part uniformly for all pages and prints out multiple pages on one page, wants to reliably read and use the fax transmission / reception date (usually printed at the top of the page). In this case, it is effective to confirm the image reading result near the boundary of the readable area.
[0050]
In consideration of the effective points in each printing format as described above, the user selects a printing format according to the purpose.
[0051]
Thereby, the user can easily understand the portion of the read image to be confirmed, the read image can be printed and provided to the user in a print format, and the user can easily find a page that specifies rereading.
[0052]
FIG. 5 is a diagram illustrating an example of the read re-execution management table 16a.
[0053]
The reading re-execution management table 16a stores the reading mode (scan mode) such as the document size, resolution, and density at the time of the previous (first) reading execution (previous scan) and the image storage unit 12 after the previous reading execution. Image file name (may be expressed as an address), total number of pages of the document fed (feeded) by the ADF 11a at the previous reading execution, page number of the page designated as the reading re-execution target, re-reading (re-scanning) The reading mode for each page instructed as the target of reading, the image file name (address notation is also possible) stored in the image storage unit 12 after re-reading, and the total number of pages of the document fed by the ADF 11a at the time of re-reading are stored. Each field is provided.
[0054]
If the image obtained by re-reading is in a state that requires re-reading, the re-reading management table 16a is re-created so that the re-reading can be subsequently accepted. To do.
[0055]
That is, the rescan mode and image file name at the time of read re-execution corresponding to the rescan page number to be read re-executed are changed to the read mode and image file name corresponding to each page at the time of the previous read execution. make a copy.
[0056]
Further, the total number of pages of the document fed by the ADF 11a at the time of re-reading is copied to the field of the total number of pages of the document fed by the ADF 11a at the time of the previous reading. Then, in preparation for the next read re-execution, the contents of each field at the time of the read re-execution are cleared.
[0057]
In this manner, it is possible to repeat the reading re-execution instruction by the document reading operation in document units without troublesome work.
[0058]
Next, reading processing of a document image of a document unit composed of a plurality of pages will be described with reference to the flowchart shown in FIG.
[0059]
First, the user goes to the front of the digital copying machine 2 and inputs a user ID and a user PIN assigned to each user to identify or authenticate the user by the display input unit 13 (steps 1 and 2). When the user is authenticated, the user sets a document composed of a plurality of pages of the document on the ADF 11a (step 3), and sets the reading mode of the document by the display input unit 13 and instructs the reading (step 3). 4). As a result, the image processing system starts a document reading process.
[0060]
When the user instructs the reading of the document, the control unit 16 of the image processing system reads the image of the document sequentially fed one by one by the ADF 11a according to the instruction such as the reading mode specified by the display input unit 13. The process (scan) read by the unit 11 is executed (step 5). At this time, the control unit 16 stores the images sequentially read by the image reading unit 11 in the image storage unit 12 (step 6).
[0061]
When the reading of the document placed on the ADF 11a is completed and the storage of the read images in the image storage unit 12 is completed, the control unit 16 stores the read image in the image storage unit 12 by a confirmation printing process described later. A document page (image number) is assigned to each image, image processing such as image reduction or composition is performed, and the processed image is printed (step 7).
[0062]
Here, the print format of the read image to be printed is selected by the user according to the purpose that the user wants to confirm among the various print formats as described above. The user confirms the read image by viewing the print result for confirmation printed by the digital copying machine 2 that has read the original image.
[0063]
As a result of the confirmation, if all the read images are satisfied by the user and there is no page that needs to be read again (step 8), the user instructs the display input unit 13 to end the reading, thereby The reading process is terminated.
[0064]
As a result of the confirmation, when the read image is not satisfied by the user and there is a page to be read again (step 8), the user sets the document unit document on the ADF 11a again (step 9). Then, the page number that needs to be re-executed and the reading mode for that page are input through the display input unit 13 to instruct re-execution of the original (step 10).
[0065]
At this time, the rescan page number for which the user has instructed the read re-execution is stored and managed in the read / re-execution management table 16 together with the read mode such as resolution, document size, and density set for each re-scan page by the user. Is done.
[0066]
When re-reading is instructed by the user, the control unit 16 feeds the originals one by one from the ADF 11a, refers to the contents of the reading re-execution management table 16a, and executes the re-reading instructed by the user The rereading (rescanning) process is executed only for the page (step 11).
[0067]
When all the manuscript pages are fed, the control unit 16 records the total number of pages of the fed manuscript at the time of re-reading in the reading / re-execution management table 16a. The control unit 16 compares the total number of pages of the original at the time of re-reading (re-scanning) with the total number of pages of the original at the time of the previous reading (pre-scanning). (Step 12).
[0068]
When it is determined by this determination that the number of pages is the same, the control unit 16 determines that at least the document feeding (sheet feeding) operation by the ADF 11a is effective at the time of reading two consecutive images. Then, the image read as a result of the rereading process is replaced with an image stored in the image storage unit 12 as a result of the previous reading process (step 13).
[0069]
The control unit 16 executes a differential print process for printing only the read image that has been replaced (step 14). The user confirms the re-read image based on the print result. If the re-read image is not satisfactory, the user re-reads the image. If the re-read image is not satisfactory, the process is terminated. (Step 8).
[0070]
If the number of pages at the time of the previous reading (number of pages fed by ADF) and the number of pages at the time of re-reading (number of pages fed by ADF) do not match in step 12 above, At the time of image reading, it is determined that there is a possibility that an error has occurred in the sheet feeding (document feeding) operation by the ADF 11a, and the display input unit 13 notifies the error.
[0071]
That is, when the controller 16 determines that the number of pages for rescanning does not match the number of pages for rescanning and the number of pages for rescanning is larger, there is a problem with the sheet feed by the ADF 11a at the time of the previous reading execution. Judging that there was a high possibility. Based on this determination, the control unit 16 displays a guidance on the display screen of the display input unit 13 that the document should be read again from the beginning because the previous scan was not normally performed, and the read image read at the time of the previous reading execution. Is invalidated and the process returns to step 3 (step 15).
[0072]
Further, when the number of pages of the previous scan is larger, the control unit 16 determines that there is a high possibility that there is a problem with the sheet feed by the ADF 11a at the time of re-reading. Based on this determination, the control unit 16 displays a guidance on the display screen of the display input unit 13 that the rereading process should not be performed because the rereading process has not been performed normally, and invalidates the image read at the time of rereading. Return to step 9 (step 16).
[0073]
As described above, by using a digital copying machine connected to a network, a document unit document is fed one by one by ADF, and a document image is read. The document unit read image is converted into an original size copy format, a reduced composition format, The print format is selected by the user from among the upper cutout synthesis format, the center cutout synthesis format, and the lower cutout synthesis format, and is printed with an image number assigned to each page.
[0074]
Accordingly, it is possible to effectively confirm a plurality of document images read in units of documents according to the user's purpose on the spot where the reading operation is performed.
[0075]
Further, when the reading operation of a document unit consisting of a plurality of pages is repeatedly performed until a read image satisfying the user is obtained, a page for which re-reading is designated from a document set in the ADF again in document units. Only re-reading is performed.
[0076]
As a result, it is not necessary to take out only the pages that need to be rescanned from the bundle of documents, and the document can be handled in document units, and only the pages that need to be reread are read, which is unnecessary. Processing waste such as processing time and storage capacity required for processing can be eliminated without performing page reading processing.
[0077]
Further, when the reading operation of a document unit consisting of a plurality of pages is repeatedly performed until a read image satisfying the user is obtained, a page for which re-reading is designated from a document set in the ADF again in document units. Only re-reading is performed, and only the re-read image is printed for confirmation.
[0078]
Thereby, useless print output can be avoided, and only the reread image that the user wants to confirm can be efficiently confirmed.
[0079]
Further, when the reading operation of a document unit consisting of a plurality of pages is repeatedly performed until a read image satisfying the user is obtained, the number of pages at the time of the previous reading and the number of pages at the time of the next reading If they do not match, the processing with the smaller number of pages is judged to be not normal, the scanned image by the processing with the smaller number of pages is invalidated, and the user is informed accordingly. Is.
[0080]
As a result, when the reading operation of the document in units of documents is repeated until an image satisfying the user is obtained, the re-reading operation can be surely repeated without troublesome work, which causes a reading page shift. It is possible to minimize the influence caused by the failure of feeding the document and to avoid wasteful paper printing due to the deviation of the read page.
[0081]
Next, the confirmation printing process in step 7 will be described in detail with reference to the flowchart shown in FIG.
[0082]
First, when the reading of all pages of the document is completed, the user instructs the print format for confirming the read image by the display input unit 13. At this time, the user selects the print format in consideration of the purpose of use of the read image and the point to be confirmed. Note that the user may instruct the user to select the print format at the start of reading the document.
[0083]
When the print format of the read image is selected by the user, the control unit 16 internally sets the print format selected from several options (step 21). The control unit 16 assigns the original page (image number) to the image read by the image reduction / combination unit 14 according to the set print format, and executes image reduction / enlargement / combination processing (step 22). The control unit 16 temporarily stores the reduced and combined image in the image storage unit 12, and prints and outputs the image by the printing unit 15 (step 23).
[0084]
Next, the rereading (rescanning) process in step 11 will be described in detail with reference to the flowchart shown in FIG.
[0085]
That is, when the re-execution of reading is instructed by the user, the control unit 16 starts executing the re-reading process. Here, the user sets a document to be read in the ADF 11a in document units, and instructs the display input unit 13 to specify the page number to be read again and the reading mode among the document units.
[0086]
The control unit 16 feeds (feeds) the documents on the ADF 11a one by one (step 31), and counts the pages. Then, the control unit 16 determines whether or not the counted page is a target page for reading and re-execution with reference to the reading and re-execution management table 16a (step 32).
[0087]
If the sheet feed count value is a page for which re-reading is designated by this determination, the reading mode for the page designated by the user is set by referring to the reading / re-execution management table 16a (step 33). Then, the image of the original in the set reading mode is read (step 34), and the read image is stored in the image storage unit 12 (step 35). When the reading process for the original page is completed, the ADF 11a feeds the next original sheet (step 36).
[0088]
If it is determined in step 32 that the page is not to be read again, the next document is fed (step 36).
[0089]
Each time the document is sheet-fed, the control unit 16 determines whether it is the last page of the document based on the fed document count value (step 37). If it is determined that the page is not the last page, the process returns to step 32 to repeat the process for the next page. If it is determined that the page is the last page, the control unit 16 reads and stores the number of pages of all document sheets fed in the re-execution management table 16a, and ends the re-reading process.
[0090]
Next, the printing process of the image read by the re-reading process will be described in detail with reference to the flowchart shown in FIG.
[0091]
First, when the rereading process of the document unit document is completed, the user instructs the print format for confirming the reread image by the display input unit 13. At this time, the user selects the print format in consideration of the purpose of use of the read image and the point to be confirmed. Note that the print format for the reread image may be instructed by the user at the start of rereading, or the print format instructed by the user at the previous reading of the document may be adopted.
[0092]
When the printing format of the reread image is selected by the user, the control unit 16 internally sets the printing format selected from several options (step 41). The control unit 16 targets only the re-read image, and assigns a document page (image number) for each image by the image reduction / combination unit 14 according to the set printing format, and reduces, enlarges, or combines the read image. The process is executed (step 42). The control unit 16 temporarily stores the reduced and combined image in the image storage unit 12 and prints it by the printing unit 15 to perform differential printing (step 43).
[0093]
As described above, after reading a document in units of documents, in response to the user's designation of the page to be re-read, when only the page designated for re-read is re-read, the re-read is executed. Only the read image of the selected page is printed in the selected print format.
[0094]
As a result, the user can efficiently confirm only the reread image of the reread page based on the print result of the print format that matches the purpose to be confirmed.
[0095]
【The invention's effect】
As described above in detail, according to the present invention, when an image processing system using a device connected to a network and shared by a plurality of users reads a document image consisting of a plurality of pages, the reading operation is executed. It is possible to provide an image processing system that can check a read image on the spot and make it easy to understand a portion of the read image that the user wants to check.
