Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing apparatus for extracting and storing a portion of a printed document such as a distribution material that has been added by handwriting.
[0002]
[Prior art]
In general, an application form for insurance, for example, is a standard sheet in which an ID number representing the form is written in a predetermined position and a predetermined area, and an entry field and an explanation field in a predetermined format are printed in advance. The name and address of the applicant and other necessary information are entered on the sheet.
[0003]
In the following explanation, a standard format that presupposes entry in such a pre-set entry field is referred to as a standard sheet, and on the contrary, it does not presuppose a specific entry (ie, entry field etc. A general manuscript without a mark) is called an atypical sheet.
[0004]
Then, when saving the filled-in fixed form sheet as described above in an electronic file or the like (hereinafter referred to as electronic storage), the filled-in fixed form sheet itself is not stored electronically but only the filled-in part is stored electronically. A method has been proposed. Thereby, the storage capacity can be extremely reduced.
[0005]
In this method, first, an unfilled fixed form sheet is stored as an electronic original (original) together with an ID number in a storage means.
[0006]
When saving the filled standard sheet, the filled standard sheet is first read by a scanner and digitized, while the original is searched by manually inputting the ID number written on the standard sheet. To retrieve from the storage means.
[0007]
As a result, the retrieved original is compared with the completed sheet, and the difference is extracted. That is, the original is composed of text data and vector data, and the image information in the vicinity of the position of the completed sheet corresponding to the position where the original text information is present and the position where the vector information is present is erased and left. Extract the part as the part written on the sheet.
[0008]
Specifically, the presence of dots is confirmed for each read resolution pitch in the read image. If there is a dot in the original at the corresponding coordinate position, it is determined that there is no additional writing. If there is no dot in the original, the dot is left as additional writing. In this way, the presence of additional writing is confirmed over the entire surface, and the remaining portion is stored as a written portion.
[0009]
At this time, since there are some misalignment of the read image and expansion / contraction of the read image, a plurality of reference points are provided in advance, and the enlargement / reduction ratio, misalignment, and inclination are corrected. Then, when displaying or printing, the standard sheet and the entry portion may be synthesized.
[0010]
Also, in the improved proposal, the ID number is written in a predetermined part of the standard sheet. After the filled standard sheet is read by the scanner, only the predetermined part is subjected to OCR, and the ID number is automatically set. There is one that can read and retrieve the original from the storage means.
[0011]
In this way, the entry part extraction process (hereinafter referred to as comparison process) and the storage process are automated, and the work can be greatly simplified.
[0012]
Furthermore, in the improved proposal, the read image is subjected to OCR, the character part is compared with text data, the straight line part is vectorized, and the vector comparison is performed so as to reduce the noise of dirt dots due to dust on the paper. Some of them are
[0013]
[Problems to be solved by the invention]
However, in the above-mentioned conventional example, when the filled-in fixed form sheet is stored electronically, not all of it is stored electronically, but only the filled-in part is stored electronically, and when this is displayed or printed Since the standard sheet and the entry portion are combined, it takes time to search and combine at least two files to display and print one page. This is not suitable for some applications. This will be described below.
[0014]
For example, when it is an application to save what is added to an atypical printed matter (ie, atypical sheet) that does not have a format, such as a material that is written while taking a lecture, such as materials distributed at various seminars, It is unclear which page has a write and it is important to check for each page whether there is a write. This means that if there is no writing, the original can be used, and if it is stored only when there is writing, a smaller storage capacity is required. In addition, although it is the same to use a small capacity, in the case of atypical, it may be necessary to write little in the distributed material. Even if unprinted print pages are continuous, it is not abnormal and is natural.
[0015]
On the other hand, in the case of a standard sheet, since the writing is basically premised, the check is unnecessary. Note that it is effective to check if there is an error process that includes an unfilled sheet, or an alarm process that may cause a circuit failure by detecting that the error process continues continuously.
[0016]
In addition, as an item resulting from the difference in use, in the case of a fixed form, the contents to be filled in are determined as an address, a name, and the like, and the place to fill in is also decided. In such cases, handwritten OCR can be used to create text, but if it is atypical, it may be necessary to emphasize important points by underlining the printed text. This is an entry in which neither the location nor the contents can be specified, such as by enclosing a part with a line, or leaving a memo in the blank when an instructor describes information that is not provided in printed matter. As described above, the properties of the standard sheet and the non-standard sheet are considerably different.
[0017]
As a summary, in the standard sheet, when storing and reproducing a sheet of multiple pages continuously, the difference part of the completed sheet is stored for the same original, and when displaying and printing this continuously, it is the same Since the file of the difference part is searched and combined with the original of the file, the file access is only required once, but the original is different for each page in the storage and playback of what was added to the atypical printed matter, and the unfilled manuscript In some cases, only one access to the original is required. However, in the case of displaying and printing a completed manuscript, it is necessary to access the file twice, and the compositing time is also long. In particular, when displaying, the waiting time is different for each page, and there is a disadvantage that it has a sense of incongruity.
[0018]
An object of the present invention is to provide an image processing apparatus that can effectively handle an atypical sheet.
[0019]
[Means for Solving the Problems]
The present invention uses printing means for printing out an electronic manuscript, an electronic manuscript main body and its related information, a storage means for storing document ID information for specifying the electronic manuscript main body and its storage destination, and document ID information. Search means for searching the electronic document body from the storage means, image reading means for reading the document and converting it into electronic information, data of the electronic document body searched from the storage means, and reading from the image reading means. A comparison unit that compares the data of the electronic document body that has been received to determine whether there is a difference greater than or equal to a predetermined value, and information indicating a page in which a difference greater than or equal to the predetermined value is detected based on a result of the comparison; Difference detection storage means for storing image data of the page or difference image data, the document ID information, and new document ID information for the new document in the storage means Other are characterized by having a difference extracting storage means.
[0020]
Further, the present invention provides a search sheet creation unit that creates a search sheet including the document ID information, and a search sheet recognition unit that extracts document ID information from a search sheet included in search sheet data read by the image reading unit. The search means searches the electronic document main body from the storage means using the document ID information extracted by the search sheet recognition means. Furthermore, the search sheet creation means outputs the created search sheet to the printing means so as to be positioned on the first page or the last page of the electronic original body when printing out the electronic original body.
[0021]
The search sheet creation means includes an identification pattern for identifying a predetermined mark sheet, a pattern indicating the document ID information, a character pattern representing the document ID information as a human recognizable character, An image obtained by extracting a part of a document or an index image based on a reduced image of a specific page is arranged on one page.
[0022]
Further, the difference detection storage means or the difference extraction storage means includes page information indicating a page in which a difference of a predetermined value or more is detected, read image data of a page in which a difference of a predetermined value or more is detected, or difference image data, and a predetermined value or less. The page information indicating the difference page, the information indicating that there is no difference for the difference pages equal to or less than the predetermined value, the original document ID number, and the new document ID number for the new manuscript generated in the current operation are stored in the memory. It is memorized in the means.
[0023]
In the present invention, when the electronic manuscript is printed out, the electronic manuscript, its related information, and its document ID information are stored in the storage means.
[0024]
As an example of operation with the above-described configuration, for example, when printing an electronic document, a mark sheet (a character symbol that can be recognized by humans, etc.) on which a document ID number that can specify the location of the original is described on the first sheet is described. Attached with a mark code that can be recognized by the machine) and printed out. At the same time as this printout, the electronic image information is stored as the original of the electronic original together with the related information of the electronic original.
[0025]
Then, by sequentially reading the printed matter additionally written in these printed matter in the document feeder and reading it continuously, the image processing apparatus automatically reads the ID number from the mark code of the first read sheet. The original corresponding to the ID number is retrieved from the storage means, and the retrieved original is compared with the second and subsequent pages of the read image. For a page having a difference, information indicating the page and the read page are compared. Is stored in the storage means as a new document, and information indicating that there is no difference from the information indicating the page is stored in the storage means for a page having no difference. At this time, the ID number of the original and the document ID number for the new manuscript due to the page having the difference generated in the current operation are stored in the storage unit for each page.
[0026]
In addition, when displaying or printing an additionally written document, a search unit searches for a different image data file or an original image data file from the old and new document ID numbers, and the page with the difference is the image data of the new document. Is displayed and printed, and the original image data is displayed and printed on a page having no difference.
[0027]
In this way, each page can be displayed and printed with a single access, so that rapid processing can be performed, and discomfort during display can be eliminated.
[0028]
Instead of processing in units of pages as described above, for partial pages, only the partial information of the different images is stored, and when displayed or printed, it is combined with the original and output. Is also possible. In this case, although access at the time of display and printing is somewhat inefficient, other functions according to the present invention, that is, storage and retrieval of originals that are expected to be atypical writing and originals after writing, etc. With respect to the function, it is possible to obtain a sufficient effect.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram showing a configuration of an image processing apparatus according to an embodiment of the present invention.
[0030]
The reader unit 1 reads an image of a document and outputs image data corresponding to the document image to the printer unit 2 and the image input / output control unit 3. The printer unit 2 records an image corresponding to the image data from the reader unit 1 and the image input / output control unit 3 on a recording sheet. The image input / output control unit 3 is connected to the reader unit 1 and includes a facsimile unit 4, a file unit 5, a computer interface unit 7, a formatter unit 8, an image memory unit 9, a core unit 10, and the like.
[0031]
The facsimile unit 4 decompresses the compressed image data received via the telephone line, transfers the decompressed image data to the core unit 10, and compresses and compresses the image data transferred from the core unit 10. The compressed image data is transmitted via a telephone line. The facsimile unit 4 is connected to the hard disk drive unit 12 and can temporarily store the received compressed image data.
[0032]
A magneto-optical disk drive unit 6 and a hard disk drive unit 11 are connected to the file unit 5, and the file unit 5 compresses image data transferred from the core unit 10, along with keywords for searching the image data, It is stored in a magneto-optical disk or hard disk set in the magneto-optical disk drive unit 6.
[0033]
Further, the file unit 5 searches the compressed image data stored in the magneto-optical disk or the hard disk based on the keyword transferred via the core unit 10, and reads and decompresses the searched compressed image data. Then, the decompressed image data is transferred to the core unit 10. The computer interface unit 7 is an interface between the personal computer or workstation (PC / WS) 11 and the core unit 10. The formatter unit 8 develops code data representing an image transferred from the PC / WS 11 into image data that can be recorded by the printer unit 2, and the image memory unit 9 temporarily stores the data transferred from the PC / WS 11. It is something to remember. Although the core unit 10 will be described later, the core unit 10 controls the flow of data among the reader unit 1, the facsimile unit 4, the file unit 5, the computer, the interface unit 7, the formatter unit 8, and the image memory unit 9. Is.
[0034]
FIG. 2 is a cross-sectional view showing the structure of the reader unit 1 and the printer unit 2.
[0035]
The document feeder 101 of the reader unit 1 feeds documents one by one on the platen glass 102 sequentially from the last page, and discharges the documents on the platen glass 102 after the document reading operation is completed. When the original is conveyed onto the platen glass 102, the lamp 103 is turned on, and the movement of the scanner unit 104 is started to expose and scan the original.
[0036]
The reflected light from the original at this time is guided to a CCD image sensor (hereinafter referred to as CCD) 109 by mirrors 105, 106, 107 and a lens 108. Thus, the scanned image of the original is read by the CCD 109. The image data output from the CCD 109 is subjected to predetermined processing and then transferred to the printer unit 2 and the core unit 10 of the image input / output control unit 3.
[0037]
The laser driver 221 of the printer unit 2 drives the laser light emitting unit 201 and causes the laser light emitting unit 201 to emit laser light corresponding to the image data output from the reader unit 1. The laser beam is irradiated onto the photosensitive drum 202, and a latent image corresponding to the laser beam is formed on the photosensitive drum 202. A developer is attached to the latent image portion of the photosensitive drum 202 by the developing unit 203.
[0038]
Then, at the timing synchronized with the start of laser light irradiation, the recording paper is fed from either the cassette 204 or the cassette 205 and conveyed to the transfer unit 206, and the developer attached to the photosensitive drum 202 is transferred to the recording paper. To do. The recording paper on which the developer is placed is conveyed to the fixing unit 207, and the developer is fixed to the recording paper by the heat and pressure of the fixing unit 207. The recording paper that has passed through the fixing unit 207 is discharged by the discharge roller 208, and the sorter 220 stores the discharged recording paper in each pin and sorts the recording paper. Note that the sorter 220 stores recording paper in the uppermost bin when sorting is not set.
[0039]
When double-sided recording is set, the recording paper is conveyed to the discharge roller 208, and then the rotation direction of the discharge roller 208 is reversed and guided to the refeed conveyance path by the flapper 209. If multiple recording is set, the flapper 209 guides the recording sheet to the refeed conveyance path so that the recording sheet is not conveyed to the discharge roller 208. Then, the recording sheet guided to the refeed conveyance path is fed to the transfer unit 206 at the timing described above.
[0040]
FIG. 3 is a block diagram illustrating a configuration of the reader unit 1.
[0041]
The image data output from the CCD 109 is subjected to analog / digital conversion by the A / D / SH unit 110 and subjected to a shoeing correction. The image data processed by the A / D / SH unit 110 is transferred to the printer unit 2 through the image processing unit 111 and also transferred to the core unit 10 of the image input / output control unit 3 through the interface unit 113. The The CPU 114 controls the image processing unit 111 and the interface unit 113 according to the setting content set by the operation unit 115.
[0042]
For example, when a copy mode for performing copying by performing trimming processing at the operation unit 115 is set, the trimming processing is performed by the image processing unit 111 and transferred to the printer unit 2. When the facsimile transmission mode is set on the operation unit 115, the interface unit 113 causes the control data corresponding to the image data and the set mode to be transferred to the core unit 10. Such a control program of the CPU 114 is stored in the memory 116, and the CPU 114 performs control while referring to the memory 116. The memory 116 is also used as a work area for the CPU 114.
[0043]
FIG. 4 is a block diagram illustrating a configuration of the core unit 10.
[0044]
Image data from the reader unit 1 is transferred to the data processing unit 121, and a control command from the reader unit 1 is transferred to the CPU 123. The data processing unit 121 performs image processing such as image rotation processing and scaling processing, and the image data transferred from the reader unit 1 to the data processing unit 121 is transferred to the control command transferred from the reader unit 1. In response, the data is transferred to the facsimile unit 4, the file unit 5, and the computer interface unit 7 via the interface 120. Further, code data representing an image input via the computer interface unit 7 is transferred to the data processing unit 121 and then transferred to the formatter unit 8 to be developed into image data. After being transferred to 121, it is transferred to the facsimile unit 4 and the printer unit 2.
[0045]
Image data from the facsimile unit 4 is transferred to the data processing unit 121 and then transferred to the printer unit 2, the file unit 5, and the computer interface unit 7. The image data from the file unit 5 is transferred to the data processing unit 121 and then transferred to the printer unit 2, facsimile unit 4, and computer interface unit 7. The CPU 123 performs the above-described control according to the control program stored in the memory 124 and the control command transferred from the reader unit 1. The memory 124 is also used as a work area for the CPU 123.
[0046]
In this way, processing that combines functions such as reading of an original image, printing of an image, transmission / reception of an image, storage of an image, and input / output of data from a computer can be performed with the core unit 10 as a center. .
[0047]
Next, the additional write extraction processing operation of the image processing apparatus according to the first embodiment of the present invention will be described with reference to FIGS.
[0048]
FIG. 5 is an explanatory diagram showing a format of a search type mark sheet 2010 (hereinafter referred to as a search sheet) in the file unit 5.
[0049]
In FIG. 5, 2011, 2012, 2013, 2014, and 2015 are mark sheet detection patterns, and 2020 is a display column for document information. In the document display field 2020, including the document location, the document ID number, server name, document name, document number, document update date, number of images in the document, paper size at the time of document recording, etc. can be specified. Is displayed. Among these, 2029 is a document ID number (4Fcopy@ccm.jp.12345622 in the illustrated example).
[0050]
Reference numeral 2021 denotes a setting field for automatic extraction storage after search, and reference numeral 2023 denotes a mark field for actual marking. Reference numeral 2022 denotes a mark field that is set as default when the mark is omitted. If the mark column 2023 is not marked, only the search is performed and the standby state is entered.
[0051]
On the other hand, in the case of marking in the mark field 2023, in the example shown in the figure, the original of the document name “catalog” is retrieved, and compared with the completed manuscript following this sheet, the added part is extracted and saved together with related information. do.
[0052]
Similarly, reference numeral 2100 denotes a mark field in which it is possible to set whether to automatically print after retrieval. Reference numeral 2024 denotes an image document name display column, and 2025 denotes a column in which an image as an image document name is entered by handwriting.
[0053]
Reference numeral 2026 denotes image data stored with the document name “catalog” described above. Reference numeral 2027 denotes that the image data 2026 is the first of the two.
[0054]
Reference numeral 2028 denotes a mark code which includes information for identifying a document having a document name of “catalog” of a server having a search sheet type and a server name “head office 4th floor copying machine HD”, that is, information such as an Internet homepage address. It is described by a pattern code. In this embodiment, it is assumed that a mark code corresponding to the document ID number (4Fcopy@ccm.jp.12345622) is described.
[0055]
FIG. 6 is an explanatory diagram showing a functional block configuration and a processing flow in the present embodiment.
[0056]
The electronic document 4001 is code data representing an image transferred from the PC / WS 11 and input to the formatter unit 8 as described above, and is commonly referred to as PDL (page description language).
[0057]
The electronic document 4001 is developed into an electronic image 4009 by the formatter unit 8 and becomes a document printed material 4002 through the printing unit 3001 configured by the printing unit 2.
[0058]
Here, the printing unit 3001 has a function of passing the formatter unit 8 when the electronic document is not code data but image data.
[0059]
The printing order is a so-called last page-first process in which the last page is put out first. Then, the front page is printed so that the first page comes to the front cover upon completion.
[0060]
At the same time as this printing, not only text information and vector information obtained from the code data but also image data is divided into areas such as text, images, titles, tables, etc. The destination server name, document name, document number, document update date, number of images in the document, paper size at the time of document recording, and the like are stored in the storage unit 3002 together with the electronic image 4009 as related information 4010.
[0061]
At this time, the document is specified, and the document ID number 2029 for specifying the storage destination is also stored and stored. This process is performed in the file unit 5.
[0062]
The storage destination is the hard disk drive 13 of the file unit 5 connected to the core unit 10 connected to the printer unit 2 by default. Of course, the storage destination can be changed to the magneto-optical disk drive 6 instructed by the PC / WS 11 or the operation unit 115, or can be designated to an arbitrary file server 15 on the network 14.
[0063]
Further, the search sheet creation unit 3003 in the file unit 5 outputs and prints the search sheet 2010 through the printing unit 3001 immediately after the printing.
[0064]
At this time, since the search sheet 2010 is finally output and printed, the search sheet 2010 is output on the printed original document 4002 and becomes a cover.
[0065]
A printed matter output with the search sheet 2010 as a cover is referred to as an unfilled printed matter 4004.
[0066]
Thereafter, the unfilled printed matter 4004 is distributed, and passes through a process 4005 in which a handwritten additional writing such as a memo or comment is made. The printed material after this process 4005 is referred to as a completed printed material 4006.
[0067]
Here, marking is performed in the mark field 2023 in the setting field 2021 for automatic additional recording after searching the cover search sheet 2010, and an automatic additional recording is instructed.
[0068]
Next, the completed printed matter 4006 is read in the form of an electronic image 4007 by the image reading means 3004 with an auto document feeder, and the document ID number is extracted from the first page by the mark sheet recognition means 3005 in the file section 5.
[0069]
Then, using the extracted document ID number, the electronic image (original) information and the related information are searched from the storage unit 3002.
[0070]
The mark sheet recognizing unit 3005 automatically instructs the comparison unit 3007 and the difference detection storage unit 3008 to execute the additional write extraction storage by recognizing the automatic additional write extraction storage setting column 2021 after the search.
[0071]
The comparison unit 3007 compares the retrieved information with the read image data and detects whether there is a difference greater than a predetermined value.
[0072]
Basically, the scanned image is scanned and the presence of dots is checked for each resolution pitch. If there are dots, if there is a dot in the original for the corresponding coordinate position, it is determined that there is no additional writing. However, if there is no dot in the original, the dot is left as if there was a postscript. Such processing is performed over the entire surface, and the existence of additional writing is confirmed.
[0073]
At this time, because there is a dot other than handwritten additional writing due to some misalignment of the read image, expansion / contraction of the read image, and dirt, a predetermined error amount is determined in advance according to the document size, and the additional write dot more than the predetermined If there is no determination of the existence of, there is no additional writing.
[0074]
The difference detection storage means 3008 is located in the file unit 5 and, for a page in which a difference greater than or equal to a predetermined value is detected from the comparison means 3007, the page information of which page and the image data of the read page are less than the predetermined value. In the difference page, page information of which page and information indicating no additional recording are stored in the storage unit 3002 for each page.
[0075]
Then, after the last page is stored, the document ID number is stored in order to leave the original image to which the original is added, and a new document ID for the current new manuscript constituted by the extracted additional pages Create numbers and store them in memory. At this time, the difference detection storage means 3008 stores the original in the storage means 3002 in which the original exists by default, but in the same way as when storing the original, the PC / WS 11 or the operation unit 115 designates the storage destination to the magneto-optical disk. It can be changed to the drive 6 or can be designated to an arbitrary file server 15 on the network 14.
[0076]
Here, the new document ID number must not be duplicated with other numbers. For example, if a new document ID number is created by a combination of a number that can specify the location of the storage means such as an Internet address, and the year, hour, minute, and second. Good.
[0077]
In addition, when displaying or printing the additionally recorded printed matter stored as described above, a document ID number is input based on reading or recognition of a search sheet or manual input from an operation unit, and a search is performed from the document ID number. Based on the page information retrieved by the means 3006 and stored by the difference detection storage means 3008, the page with the difference displays and prints the image data of the new original, and the page without the difference displays the original image data. Try to print. As a result, each page can be printed and displayed with a single file access, so that the access time is shorter than when the original image data and the image data of the difference portion are accessed and combined and output. In addition to being shortened, the operation becomes smooth, and there is no particular discomfort in the display.
[0078]
In the present embodiment, the postscript extraction is performed for the pages after the search sheet. However, since the search sheet can also be compared, it is possible to extract the additional write including the search sheet.
[0079]
As described above, according to the present embodiment, when an electronic manuscript is printed out and created, the electronic manuscript is simultaneously stored and saved, and a search sheet in which a document ID number for specifying the manuscript is embedded is used. Print it out in an electronic manuscript. Thereby, it is possible to easily create a manuscript (unfilled printed matter) including the search sheet.
[0080]
In addition, when such unfilled printed material is distributed and added to the printed material by hand, the completed printed material is simply set in the auto document feeder and reading is started, based on the mark on the search sheet. Since only the additional pages are extracted and compressed storage is automatically performed, it can be applied to non-standard-format materials whose format is not fixed for use in various workshops, etc. You can save and save well. Furthermore, when printing and displaying such a completed printed matter, since there is only one file access on any page with no difference, it can be printed and displayed at high speed.
[0081]
Next, a second embodiment of the present invention will be described.
[0082]
In the first embodiment, the image data is processed on a page-by-page basis, depending on whether or not additional writing is performed in the additional writing extraction processing. In other words, for pages with additional writing, the entire image data of the page is stored, and when printing or displaying, pages without additional writing access the original file, and pages with additional writing are newly stored. I was trying to access the image data file.
[0083]
However, in this second embodiment, for pages with additional writing, only the difference portion is extracted and stored, and when printing or displaying, the page without additional writing accesses the original file, The page with additional writing accesses the original file and the newly stored image data file of the difference portion, combines them, and prints or displays them.
[0084]
Therefore, in the second embodiment, the page with additional writing requires two times of file access and further requires time for compositing. Therefore, in terms of smoothness in printing and display, the first embodiment is performed. Although it is inferior to the example, since only the difference portion is stored for a page with additional writing, it is advantageous in terms of memory efficiency.
[0085]
FIG. 7 is an explanatory diagram showing the configuration of functional blocks and the flow of processing in the second embodiment. The search sheet is the same as that shown in FIG. 5 of the first embodiment, and a description thereof will be omitted.
[0086]
In FIG. 7, the difference from the first embodiment is that a difference extraction storage means 3009 is provided instead of the difference detection storage means 3008 described above.
[0087]
When the difference extraction storage unit 3009 is in the file unit 5 and performs the additional extraction process, the page information of which page and the image data of the additional portion are included in the page in which a predetermined difference or more is detected from the comparison unit 3007. Are stored in the storage means 3002 for each page for page information of which page and information indicating no additional writing.
[0088]
