Description

  The present invention relates to an image reading apparatus that optically reads an image, and more particularly to a technique for improving user convenience when reading a book or a document.

  When reading a document that covers a plurality of pages, such as a book or a document, with a scanner or a copying machine, the user needs to read the pages while changing the pages one page at a time. When such a monotonous task is repeated endlessly, humans often make mistakes. Mistakes here are, for example, skipping necessary pages, reading the same page repeatedly, or reading unnecessary pages even after reading necessary pages. Is. In general, it is difficult to find such mistakes because they make them without even being aware of them.

  Some scanners and copiers include an automatic document feeder (ADF) that continuously reads a document of a plurality of pages. ADF is very powerful when reading a large amount of documents, but it may cause so-called “multiple feeding” that feeds multiple documents in a stack, and in such a case, some pages are missing. Will be read.

In order to avoid these disadvantages, Patent Document 1 reads the number of pages from each document during continuous copying, and notifies the user after completion of continuous copying if the number of pages has not increased continuously. Techniques to do this are disclosed. If such a technique is used, the user can easily recognize the missing page, so that the missing page can be supplemented by additional copying.
JP 2002-139965 A

  However, when the technique described in Patent Document 1 is used, in order to complement the missing page, (1) the document of the missing page is searched from the document, and (2) the document is searched. The manuscript is copied, (3) the missing page is identified from the multi-page copy, and the copy copied in (4) and (2) is inserted into the location specified in (3). The user needs to perform extremely complicated work. In particular, the operation (2) of identifying a missing page portion is extremely difficult when the document has an enormous number of pages.

  Further, in the technique described in Patent Document 1, since each page is compared on the basis of the page number, there is a disadvantage that it is not effective for a document in which the page number is not displayed.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to output a document extending over a plurality of pages in a preferable manner without inconvenience to the user.

In order to achieve the above-described object, an image reading apparatus according to the present invention includes a reading unit that reads a plurality of documents on which page numbers are displayed one by one and sequentially generates image data representing each document; An extraction unit that extracts a page number from the image data generated by the reading unit, and the extraction unit extracts a first page number from the first image data, and immediately after that, a second number is extracted from the second image data. If the difference between the first page number and the second page number is not 1 when the page number is extracted, the deletion unit deletes the second image data and the reading unit generates the page number. And an output unit that outputs image data that is not deleted by the deleting unit.
Alternatively, the image reading apparatus according to the present invention reads a plurality of originals on which page numbers are displayed one by one and sequentially generates image data representing each original, and the reading means generates the image data. When the extraction means for extracting the page number from the image data, and the extraction result by the extraction means, N is an integer greater than or equal to 3, d is a positive or negative integer, and P is an integer greater than 2d, (N -2) If the page number is (P-2d), the (N-1) th page number is (P-d), and the Nth page number is not P, the N A deletion unit that deletes the image data of the first sheet; and an output unit that outputs image data generated by the reading unit and not deleted by the deletion unit.

  According to such an image reading apparatus, when it is detected that the page number is irregularly increased (or decreased), the image data from which the page number is extracted is deleted. That is, only the image data whose page number is regularly increased (or decreased) is output by the output means.

The image reading apparatus according to the present invention reads a plurality of originals on which page numbers are displayed one by one, sequentially generates image data representing each original, and the reading means generates the image data. Extraction means for extracting the page number from the image data, and when the extraction means extracts the first page number from the first image data and immediately after that extracts the second page number from the second image data In addition, when the first page number and the second page number are not the same and the difference is not 1, the value is larger than the first page number and smaller than the second page number, Alternatively, the second storage means for storing a value larger than the second page number and smaller than the first page number, and the page number of the image data extracted by the extraction means. Determining means for determining whether or not the value matches the value stored in the second storage means, and if the determination result of the determination means is affirmative, the image of each page from the first storage means Output means for reading out the data and the page number and outputting the image data in the order in which the page number increases or decreases;
Alternatively, the image reading apparatus according to the present invention reads a plurality of originals on which page numbers are displayed one by one and sequentially generates image data representing each original, and the reading means generates the image data. Extraction means for extracting page numbers from image data; first storage means for storing image data generated by the reading means; and page numbers of the image data extracted by the extraction means in association with each other; When the extraction result by the extraction unit is N as an integer of 3 or more, d as a positive or negative integer, and P as an integer greater than 2d, the (N-2) th page number is (P-2d). ) And (N−1) th page number is (Pd) and the Nth page number is not P, it is larger than (Pd) and smaller than the Nth page number. Value or Nth page A second storage means for storing a value larger than the number (Pd) and a value stored in the second storage means for the image data from which the page number has been extracted by the extraction means; If the judgment result of the judgment means is positive and the judgment result of the judgment means is affirmative, the image data and page number of each page are read from the first storage means, and the page number increases. Alternatively, output means for outputting the image data in a decreasing order.

  According to such an image reading apparatus, even when the page number is irregularly increased (or decreased) and the read page is missing, image data corresponding to the missing portion is input thereafter. For example, the image data is sorted (rearranged) and output in the order in which the page numbers regularly increase (or decrease).

  The image reading apparatus according to the present invention reads a single document that is a plurality of originals representing a document and that displays classification information that is a character or a number indicating a document separation one by one. Reading means for sequentially generating image data representing the image data, extracting means for extracting the classification information from the image data generated by the reading means, and when N is an integer of 2 or more, the extracting means When the category information extracted in step (N-1) is different from the category information extracted in the (N-1) th image, a notification means for notifying the user of a change in document separation, and an image from which the category information is extracted by the extraction means Output means for outputting data.

  The image reading apparatus deletes the Nth image data when the classification information extracted on the Nth sheet by the extraction unit is different from the classification information extracted on the (N-1) th sheet. It is desirable for the configuration to include a deleting unit.

  According to such an image reading apparatus, it is possible to notify a user of a document delimiter by extracting section information such as a chapter number and a chapter title indicating a document delimiter. Therefore, even if the page number is not displayed on the document, it is possible to eliminate the inconvenience of reading even an unnecessary part of the document without the user's knowledge.

  As described above, according to the present invention, it is possible to output a document extending over a plurality of pages in a suitable manner without inconvenience to the user.

[1. Constitution]
In the following, preferred embodiments of the present invention will be illustrated and described in detail with reference to the drawings. FIG. 1 is a block diagram showing an image reading apparatus 100 according to an embodiment of the present invention. The image reading apparatus 100 includes an image reading unit 1, an information extraction unit 2, a storage unit 3, a UI (User Interface) unit 4, an image output unit 5, and a control unit 6.

  The image reading unit 1 has a so-called scanner function, and optically reads a document placed on a platen glass and generates image data representing the document. The image reading unit 1 may include a so-called ADF (Auto Document Feeder) that continuously reads a plurality of pages of documents one by one. When the image reading unit 1 does not include the ADF, the user may read the pages one by one.

  The information extraction unit 2 performs OCR (Optical Character Recognition) processing on the image data generated by the image reading unit 1 and extracts identification information such as a page number and a chapter number from each image data. The information extraction unit 2 can extract the identification information from an arbitrary position of the image data. However, when a document whose identification information position is determined in advance is to be read, an OCR process is performed only on that position. You may give it. For example, the OCR process may be performed only on a so-called footer region of the document or a position corresponding to the lower part or the lower center of the document. Moreover, you may comprise so that a user can designate the position used as reading object. With such a configuration, identification information can be extracted with high accuracy.

  The storage unit 3 is a storage device such as a hard disk and can store various data. The UI unit 4 is an input device that includes a touch panel, a speaker, and buttons, and notifies the user of various types of information and receives input from the user. The image output unit 5 outputs the image data to an external device such as a printer or a storage device. The control unit 6 is an arithmetic processing unit including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like, and from reading to output by executing a program stored in the ROM. Control the operation of each part up to.

[2. Operation]
With the above configuration, the image reading apparatus 100 reads a document and outputs it to an external device. At this time, the image reading apparatus 100 extracts identification information from the image data, and determines a subsequent operation based on the extracted information. Accordingly, the operation of the image reading apparatus 100 will be described below with an operation example corresponding to the identification information. Here, an operation when the image reading apparatus 100 continuously reads a document will be described.

[2-1. Operation example 1]
Here, an operation when the identification information is a page number and a page is missing will be described. Here, “missing page” means a case where the increase of the page number becomes irregular, such as 1 (page), 2 (page), 3 (page), 5 (page)... To do. Of course, not only the case where the page number increases regularly but also the case where the page number decreases regularly can be included.

  For example, when trying to read a book in a spread state, that is, when the left and right pages are facing each other, this page number is 2 (page), 4 (page), 6 (page) ... And so on. Similarly, when only one side of an original that has been copied on both sides is to be read continuously, the page number increases to 2 (page), 4 (page), 6 (page), and so on. Go. Even in such a case, it can be said that the page number is regularly increasing. In other words, generalizing the above “missing pages” can be rephrased as “when the page number that has been increased (or decreased) by the same difference until then has not increased (or decreased) by the same difference”.

2 and 3 are flowcharts showing processing performed by the image reading apparatus 100 in this operation example, and will be described below with reference to these drawings. First, the control unit 6 of the image reading apparatus 100 performs a series of processes for generating and storing image data (hereinafter referred to as “image data storage process”) (S101). FIG. 3 shows this image data storage process in detail. That is, in this step, the control unit 6 causes the image reading unit 1 to read a document to generate image data (S1), counts what number of the read document is (S2), and is generated. The page number of the image data is extracted by the information extraction unit 2 (S3), and the image data and the page number are stored in the storage unit 3 (S4). In the following, the counted count value in step S2 N, N-th page number extracted in step S3 and P _N. The storage unit 3, for each of the image data, will store in relationship to the count value N and the page number P _N.

  After storing the image data, the control unit 6 determines whether or not the immediately preceding count value N is larger than 2 (S102). The reason why this process is performed is that after the page numbers for at least two pages are extracted, it is not possible to specify how the page numbers increase or decrease (a value d described later cannot be calculated). Because. Therefore, if the immediately preceding count value N is 2 or less (S102; NO), the control unit 6 performs the image data storage process again.

When the immediately preceding count value N is larger than 2, that is, when image data for three pages or more is generated (S102; YES), the page number P _N of the image data read for the Nth sheet and (N -1) It is determined whether or not the difference between the page numbers _PN-1 of the image data read for the first sheet is a predetermined value d (S103).

The calculation of the value d is the page number P _N-2 of the (N-1) th from the page number P _N-1 of the image data read in (N-2) th image data read in It is obtained by subtraction. That is, given the page number P _N to be arithmetic progression, the value d is equivalent to the tolerance of the arithmetic progression. For example, the value d when the page number increases regularly by 1 is “1”, the value d when the page number decreases regularly by 2 is “−2”, and so on. Further, when the value d is set to a predetermined value (for example, “1”), it is not necessary to calculate the value d, and therefore the process of step S102 can be omitted.

In step S103, when the page number difference “P _N −P _N−1 ” is equal to the value d (S103; YES), the control unit 6 determines that the increase (or decrease) in the page number is regular. Then, the page number _PN is displayed on the touch panel of the UI unit 4 (S104). On the other hand, if the difference between the page number _{"P N -P N-1"} is different from the value d (S103; NO), the control unit 6 infers the page number _{P X} that corresponds to the page missing, this Is temporarily stored in the RAM (S105). Page number P _X, for example, (N-1) th or subtracting the page number P _N-1 from the value d of the image data read in, the page number of the image data read in the N-th P _N Is obtained by adding the value d to. At this time, the control unit 6 notifies the user of a warning with a content such as “There was a missing page” via the UI unit 4 (S106).

Thereafter, the control unit 6 continues to execute the image data storage process (S107). This process is the same as the process of step S101. Subsequently, the control unit 6 determines the difference between the page numbers in the same manner as in step S103 (S108). If the affirmative determination at this time (S108; YES), the control unit 6 to display the page number _{P N} on the touch panel of the UI unit 4 (S109). This process is the same as step S104. On the other hand, if the negative and the determination of this time (S108; NO), the control unit 6 determines whether the page number P _N just before the page number P _X stored in the RAM matches ( S110).

If these page numbers match (S110; YES), it means that the missing page has been supplemented by an interruption or the like by the user, so the control unit 6 displays the page number P _{N on} the touch panel of the UI unit 4. Is displayed (S109). On the other hand, if these page numbers do not match (S110; NO), it means that the page is missing again. Therefore, if the page numbers do not match, the same processing as in steps S105 and S106 described above is executed (S111 and S112).

  When the above processing is completed, the control unit 6 determines whether all the originals have been read (S113). In this process, if the image reading unit 1 has an ADF, it is only necessary to determine whether the document is placed on the ADF. If the image reading unit 1 does not have an ADF, the document What is necessary is just to judge whether reading is not performed more than predetermined time. If there remains a document to be read (S113; NO), the control unit 6 repeats the processing from step S107 described above. On the other hand, when all the originals have been read (S113; YES), the control unit 6 sorts the image data stored in the storage unit 3 and outputs them in the order in which the page numbers increase or decrease regularly. (S114).

  When the image reading apparatus 100 performs such processing, the user can instantly know that a page is missing. At this time, since the user can easily identify the original of the missing part, the user can read back the original by one page, read the original, or interrupt the original that has been double-fed. Can be complemented. In addition, since the image reading apparatus 100 sorts and outputs the image data, the document may be interrupted at any timing. Therefore, according to the image reading apparatus 100, it is possible to output documents over a plurality of pages in an appropriate order without inconvenience to the user.

[2-2. Operation example 2]
In the operation example 1 described above, it is assumed that a page is missing when “a page number that has been increased (or decreased) by an equal difference has not increased (or decreased) by an equal difference”. Processed. However, in the case where “the page number that has been increased (or decreased) by an equal difference has not increased (or decreased) by an equal difference”, for example, 1 (page), 2 (page), 3 (page) 3 (pages)... And the same page number is extracted continuously. Therefore, in the following, the operation in the case where duplication occurs in the page will be described.

  FIG. 4 is a flowchart showing processing performed by the image reading apparatus 100 in this operation example, and will be described below with reference to this figure. First, the control unit 6 of the image reading apparatus 100 performs the same image data storage process as in the first operation example (S201). After storing the image data, the control unit 6 determines whether or not the immediately preceding count value N is greater than 1 (S202). The reason for performing this process is that it is not possible to determine the overlap of page numbers unless the page numbers for at least two pages are extracted. Therefore, if the immediately preceding count value N is 1 (S202; NO), the control unit 6 performs the image data storage process again.

If the previous count value N is greater than 1, that is, when the image data of more than two pages are generated (S202; YES), a page number P _N of the image data read in the N-th (N -1) It is determined whether or not the page numbers P _{N-1 of} the image data read on the first sheet are equal (S203). If P _N = not _{P N-1 (S203; NO} ), the control unit 6 determines that the page is not duplicated, and displays the page number _{P N} on the touch panel of the UI unit 4 (S204).

On the other hand, if P _N = P _N−1 (S203; YES), the control unit 6 determines that page duplication has occurred, and gives a warning such as “There was page duplication.” The user is notified via the UI unit 4 (S205). At this time, for example, a screen as shown in FIG. 5 is displayed on the touch panel of the UI unit 4. Here, the control unit 6 inquires of the user whether or not to delete the image data with the duplicate page number (S206), and changes the subsequent processing according to the user's selection.

  At this time, when the user inputs an instruction to delete the duplicate page (S206; YES), the control unit 6 deletes one of the image data of the page numbers determined to be duplicated (S207). ). On the other hand, when the user inputs an instruction not to delete the duplicate page (S206; NO), the control unit 6 leaves the duplicate page as it is.

  When the above processing is completed, the control unit 6 determines whether all the originals have been read (S208). In this process, if the image reading unit 1 has an ADF, it is only necessary to determine whether the document is placed on the ADF. If the image reading unit 1 does not have an ADF, the document What is necessary is just to judge whether reading is not performed more than predetermined time. If there remains a document to be read (S208; NO), the control unit 6 repeats the processing from step S201 described above. On the other hand, when all the originals have been read (S208; YES), the control unit 6 outputs the image data stored in the storage unit 3 in the order of reading (S209).

  When the image reading apparatus 100 performs such processing, the user can instantly know page duplication and delete it if unnecessary. Therefore, according to the image reading apparatus 100, it is possible to output documents over a plurality of pages in an appropriate order without inconvenience to the user.

  In the actual processing of the image reading apparatus 100, missing pages and overlapping pages should be considered simultaneously. Therefore, it is desirable that the processing of this operation example and the processing of the above operation example 1 are actually executed simultaneously or in combination. As described above, both missing pages and overlapping pages are “when the page number that has been increased (or decreased) by the same difference until then has not increased (or decreased) by the same difference”. Only when they are common and the page number is the same as the previous page number, the page overlaps. By utilizing this fact, it is possible to determine missing pages and overlapping pages in a single process.

[2-3. Operation example 3]
In the above-described operation example 2, when image data with the same page number exists, this is regarded as a document of the same page, and the process of deleting one is performed. However, image data with the same page number is not necessarily an original with the same page. For example, there is an error in the page number itself, and the same page number is assigned even though it is not originally the same page. Cases are also conceivable. In such a case, if any one of the image data with the same page number is deleted, information required by the user may be lost. This operation example is intended to eliminate the disadvantages in such a case.

  FIG. 6 is a flowchart showing processing performed by the image reading apparatus 100 in the present operation example. Hereinafter, a description will be given with reference to FIG. is there. Therefore, in the same figure, steps similar to those of the operation example 2 are denoted by the same reference numerals as those in FIG. 4, and description of these steps will be omitted as appropriate.

  If it is determined in step S203 that the pages overlap (S203; YES), the control unit 6 performs a process of determining the similarity between the image data having the same page number (S211). Although specific processing is not particularly limited, for example, the control unit 6 may compare two pieces of image data in units of pixels, and may determine the degree of similarity based on the degree of color difference of each pixel, or the image data May be recognized, and the degree of similarity may be determined using two image data.

  Based on the determination result, the control unit 6 determines whether or not the image data is the same, in other words, whether or not the image data is generated from the same document (S212). If it is determined that the two image data are the same (S212; YES), the control unit 6 deletes one of the image data determined to be the same (S207). Since the two image data are the same, the image data to be deleted may be either.

  On the other hand, if it is determined that the two image data are not the same (S212; NO), the control unit 6 gives a warning with a content such as “There is image data with the same page number” via the UI unit 4, for example. To the user (S213). At this time, for example, a screen as shown in FIG. 7 is displayed on the touch panel of the UI unit 4. The control unit 6 displays two pieces of image data having the same page number, and inquires of the user whether or not to delete any one of the image data (S214).

  At this time, when the user inputs an instruction to delete one of the image data (S214; YES), the control unit 6 deletes the instructed image data (S215). On the other hand, when the user inputs an instruction not to delete (S214; NO), the control unit 6 does not delete the image data having the same page number, but leaves it as it is.

  By performing such processing, the image reading apparatus 100 deletes image data with the same original document itself, and determines whether or not to delete image data with the same page number but different contents. Can be left to the user. Therefore, according to the image reading apparatus 100, it is possible to output a document over a plurality of pages without inconvenience to the user.

[2-4. Operation example 4]
The above-described operation examples 1 to 3 are all examples in which the identification information is a page number. However, the image reading apparatus 100 of the present embodiment can also extract chapter numbers and chapter titles in the same manner as page numbers. Therefore, the operation when the chapter number or chapter title is used as identification information will be described below.

  First, chapter numbers and chapter titles will be described with reference to FIGS. The chapter number is, for example, a character string displayed as “4.” in FIG. 8A, and this character string means “Chapter 4”. Similarly, the character string displayed as “5.” in FIG. 8B means “Chapter 5”. The chapter title is, for example, a character string displayed as “Basic” in FIG. 8A or a character string displayed as “Application” in FIG. 8B. The information extraction unit 2 recognizes and extracts such a character string as identification information.

  Depending on the document, for example, the same chapter may be further subdivided, such as character strings such as “4.1.” And “4.2.” Shown in FIG. The information extraction unit 2 of the present embodiment shall recognize and recognize these character strings. That is, “4.1.” In FIG. 9A is “Chapter 4 Section 1”, and “4.2.” In FIG. 9B is “Chapter 4 Section 2”. As such, each is identified as different. Therefore, hereinafter, the identification information representing the chapters and sections described above is collectively referred to as “section information”. That is, the division information is information indicating the division (separation) of a document that is a manuscript.

  8 and 9 described above show a mode in which chapter numbers and chapter titles are displayed in the header area. However, the position where the division information is displayed is not limited to such a position. Absent. The classification information may be at other positions, or the position may be different for each page.

  FIG. 10 is a flowchart showing processing performed by the image reading apparatus 100 in this operation example, and will be described with reference to this figure. First, the control unit 6 of the image reading apparatus 100 performs the same image data storage process as in the first operation example (S301). After storing the image data, the control unit 6 determines whether or not the immediately preceding count value N is greater than 1 (S302). If the immediately preceding count value N is 1 (S302; NO), the control unit 6 displays the classification information on the touch panel of the UI unit 4 (S306), and outputs image data (S307). Thereafter, the control unit 6 performs the image data storage process again.

  When the immediately preceding count value N is larger than 1, that is, when image data for two pages or more is generated (S302; YES), the classification information of the image data read for the Nth sheet and (N−1) ) It is determined whether or not the classification information of the image data read on the sheet is the same (S303). If it is determined that the category information is the same (S303; YES), the control unit 6 determines that there is no change in the document segment, and displays the category information on the touch panel of the UI unit 4 (S306). Thereafter, the control unit 6 outputs the image data generated immediately before (S307), and performs the image data storage process again.

  On the other hand, if it is determined that the category information is not the same (S303; NO), the control unit 6 determines that a change has occurred in the document separation, for example, “Chapter 4 has ended”. Is notified to the user via the UI unit 4 (S304). At this time, for example, a screen as shown in FIG. 11 is displayed on the touch panel of the UI unit 4. Here, the control unit 6 inquires of the user whether or not to continue reading the document thereafter (S305).

  When the user inputs an instruction to continue reading the document (S305; NO), the control unit 6 outputs the image data generated immediately before (S307) and performs the image data storage process again. On the other hand, when the user inputs an instruction to end the reading of the document (S305; YES), the control unit 6 ends the reading of the image. For example, when the image reading unit 1 is configured to include an ADF, the original document before reading may remain in the ADF at this time. Even in such a case, the control unit 6 finishes reading the image. Let

  By performing such processing, the image reading apparatus 100 can detect a document break based on section information such as a chapter number and a chapter title, and notify the user of this to make a determination. Therefore, according to the image reading apparatus 100, even a document in which no page number is displayed can output only a necessary portion without reading an unnecessary portion.

[3. Modified example]
In the above, the present invention has been described with reference to one preferred embodiment. However, the present invention is not limited to the above-described embodiment, and various modifications can be made. Examples of such modifications will be described below.

  In the above-described embodiment, it has been described that the information extraction unit 2 performs the OCR process to extract the identification information. However, it is not always necessary to perform the OCR process in determining whether the two pieces of identification information are the same. . For example, a difference in images corresponding to the position of the identification information may be detected, and if the difference is within a predetermined level, it may be determined that the identification information is the same.

  In the above-described embodiment, the case where the image reading unit 1 includes the ADF has been described. Of course, the image reading unit 1 may include a DADF (Duplex Auto Document Feeder). With such an aspect, it is possible to read a plurality of documents copied on both sides.

  Further, in the above-described operation example 1, when there is a missing page, it has been described that the sorted page is output after waiting for the missing page to be read. However, if a missing page is detected, It is also possible to delete the image data read in step 1 and temporarily stop the operation. Even in such an aspect, it is possible to specify the missing part. Further, when there is no missing page or when there are a plurality of pages of image data before the missing page, there is no problem even if the image data is sequentially output.
