JP 2009-100102 A JP 09-247380 A

  In ID copy / ID scan, the front and back surfaces of one ID card are individually scanned to create an image that is aggregated in 2in1, and the image is printed on a paper medium or output as electronic data. If you scan the wrong combination of front and front and back and back, you will not be able to notice the mistake unless you check the printed matter or electronic data that has been output. In addition, when a procedure error occurs when performing ID copy / ID scan for a plurality of ID cards in succession, images combining the front and back surfaces of other cards are sequentially output, which significantly wastes time and resources. It will be.

  With respect to this problem, in Patent Document 1, when scanning the front and back surfaces of a card such as a license and combining and printing it into one image, after opening and closing the front cover, it is detected that the document cover is opened or closed. Judged that it was replaced with the back side. However, in this method, if the document cover is opened and closed, it is determined that the front side is actually replaced with the back side, and when the front side of another card is set, the back side is also replaced. It will be judged.

  Also, in Patent Document 2, the number of black pixels on the specific line of the read image data is recognized as a feature of the image data so that duplicate copying is not performed, and if the features match, the page is forgotten It is judged and a warning is given. However, with this method, even if the document is rotated 180 degrees without turning it over, it is recognized as different data, and the number of black pixels on the line coincides even though it is a different page. Will be recognized as different data.

  As described above, the conventional method cannot accurately determine that the ID card is turned over, and the image on the front surface and the image on the back surface of the ID card cannot be properly associated with each other.

  The present invention has been made in view of the above problems, and its main purpose is to simply and accurately determine that the ID card has been turned over, and to appropriately determine the image on the front side and the image on the back side of the ID card. An image processing apparatus and a control program that can be associated with each other are provided.

  In order to achieve the above object, according to the present invention, in an image processing apparatus capable of selecting an operation mode for outputting the first side and the second side of a double-sided printed product in association with each other, the image reading unit and the operation mode are selected. When the first image and the second image of the double-sided printed matter read by the image reading unit are analyzed and both the first image and the second image include a specific object, or If the specific object is not included in both the one image and the second image, it is determined that the first image and the second image are not a combination of the front image and the back image of the double-sided printed matter. And a control unit for performing.

  The present invention also provides a control program that operates in an image processing apparatus that includes an image reading unit and that can select an operation mode in which the first and second surfaces of a double-sided printed product are output in association with each other. When the operation mode is selected, the apparatus analyzes the first image and the second image of the double-sided printed matter read by the image reading unit, and specifies an object specific to both the first image and the second image. Is included, or when the specific object is not included in both the first image and the second image, the first image and the second image are the front and back images of the double-sided printed material. It is made to function as a control part which judges that it is not a combination of and gives a warning.

  According to the image processing apparatus and the control program of the present invention, it is possible to easily and accurately determine that the ID card has been turned over, and to appropriately associate the image on the front surface and the image on the back surface of the ID card.

  The reason is that in the image processing apparatus (control program), when the operation mode for outputting the first side and the second side of the double-sided printed material such as an ID card in association with each other is selected, the first read from the double-sided printed material. If both the image and the second image contain a photo or a specific keyword or a specific mark, or if both the first image and the second image do not contain a photo or a specific keyword or a specific mark, the first image and This is because it is determined that the second image is not a combination of the front surface image and the back surface image of the double-sided printed material (that is, the double-sided printed material is not turned over), and a warning is given.

It is a flowchart figure which shows the process (ID copy / ID scan setting process) of the image processing apparatus which concerns on one Example of this invention. It is a figure which shows an example of the screen (ID copy / ID scan setting screen) displayed on the image processing apparatus which concerns on one Example of this invention. It is a flowchart figure which shows the process (process at the time of ID copy mode) of the image processing apparatus which concerns on one Example of this invention. It is a flowchart figure which shows the process (process at the time of ID scan mode) of the image processing apparatus which concerns on one Example of this invention. It is a flowchart figure which shows the front / back confirmation process in ID copy mode / ID scan mode of the image processing apparatus which concerns on one Example of this invention.

  As shown in the background art, in ID copy / ID scan, the front and back sides of a single ID card are individually scanned to create a 2in1 aggregated image that can be printed or output as electronic data. Therefore, it is important to reliably determine that the ID card is turned over. Therefore, in Patent Document 1, it is determined that the back of the document cover has been replaced when the opening / closing of the document cover is detected after the front surface reading process. When it is determined that the card has been replaced and the front side of another card is set, it is determined that the card has been replaced with the back side. Further, in Patent Document 2, it is determined that the page turning is forgotten by analyzing the content of the read image data in detail. However, in this method, when the document is rotated 180 degrees without turning over, a different page is used. Even if the number of black pixels on the line coincides by chance, it is recognized as different data.

  Here, a normal manuscript may have photographs on both sides or no photographs on both sides, but in the case of an ID card, there is generally a photograph on the first side (front side) and the second side (back side). Because there is no photo in the case, if there is a photo on both the first side and the second side, or if there is no photo on either the first side or the second side, it is determined that the ID card is not turned over. be able to. In addition, since the ID card is usually created according to a format unique to each card, there are specific keywords or specific marks according to the format on both the first side and the second side. If there is no specific keyword or specific mark on any of the two surfaces, it can be determined that the ID card is not turned over.

  Therefore, in one embodiment of the present invention, the ID card is turned over based on the presence or absence of a specific object such as a photo, a specific keyword, or a specific mark in consideration of the characteristics of the ID card. A simple and accurate determination is made so that the image on the front side and the image on the back side of the ID card can be associated with each other appropriately.

  Specifically, when the ID card is copied to a paper medium or output as electronic data, the ID mode is selected when an operation mode in which the first side and the second side of the ID card are output in association with each other is selected. It is determined whether the first image and the second image read from the card contain a photo or a specific keyword or a specific mark, and both the first image and the second image are a photo or a specific keyword or a specific When the mark is included, or when the photographic image or the specific keyword or the specific mark is not included in both the first image and the second image, the first image and the second image are the front image and the back surface of the ID card. It is determined that it is not a combination of images (operation mistake without turning over the ID card) and a warning is issued.

  In order to describe the above-described embodiment of the present invention in more detail, an image processing apparatus and a control program according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating an external configuration of the image processing apparatus according to the present exemplary embodiment, and FIG. 2 is a block diagram illustrating a configuration of the image processing apparatus.

  Hereinafter, processing of the image processing apparatus 10 configured as described above will be described. First, setting processing related to ID copy / ID scan will be described with reference to the flowchart of FIG. 3 and the screen example of FIG.

[ID copy / ID scan setting process]
The control unit 11 causes the display unit 13 to display a setting screen for performing settings related to ID copying / ID scanning (S101). In this setting screen, for example, as shown in FIG. 4, it is possible to select whether to use a photo, a keyword, or a barcode as an element for confirming the front and back. When is selected, a registration button for transitioning to a screen for inputting the keyword is provided.

  Then, when the user operates the operation unit 14 to check the keyword column and presses the registration button (S102: Yes), the control unit 11 displays a screen for inputting the keyword on the display unit 13. Then, the user inputs a keyword (S103), registers the input keyword in the memory 11b or the HDD 11c (S104), returns to S101, and displays the setting screen on the display unit 13. Although an arbitrary character string can be input as this keyword, a character string such as “driver's license” can be input in the case of a license in order to make the ID card identifiable.

  On the other hand, if the keyword is not registered (S102: No), the control unit 11 determines whether the OK button is pressed (S105). If the OK button is not pressed, the control unit 11 returns to S101 and maintains the display of the setting screen. If the OK button is pressed, the checked front / back confirmation element is stored in the memory 11b or the HDD 11c (S106), and the ID copy / ID scan setting process is terminated.

  When using a photo or barcode as a front / back confirmation element, you can set the photo size, color / monochrome, layout, composition, etc., and the barcode size and type (one-dimensional barcode / two-dimensional barcode). (QR code (registered trademark))), arrangement, etc. may be set, and by setting these, it is easy to distinguish between an ID card and a general manuscript including a photo or barcode. can do.

  Here, a barcode is illustrated as a specific mark of the front / back confirmation element, but the specific mark may be a mark (logo mark) for identifying the ID card issuer. In that case, logo marks of various ID cards may be registered in advance, and a predetermined logo mark may be selected from them, or may be registered by drawing a logo mark on the touch panel.

  Next, processing when the ID copy mode is selected after setting for ID copy / ID scan will be described with reference to the flowchart of FIG.

[Processing in ID copy mode]
First, the control unit 11 (control program) displays a message such as “Please set the front surface” on the display unit 13 and installs the front side of the ID card in the image reading unit 12 (S201). Then, the control unit 11 (control program) monitors the pressing of the start button (S202), and when detecting the pressing of the start button, operates the image reading unit 12 to perform the first scan (scanning of the surface of the ID card). (S203), and the scan image (surface image) data is stored in the memory 11b or the HDD 11c.

  Next, the control unit 11 (control program) displays a message such as “Please set the back side” on the display unit 13 and installs the back side of the ID card in the image reading unit 12 (S204). Then, the control unit 11 (control program) monitors the pressing of the start button (S205), and when the pressing of the start button is detected, the image reading unit 12 is operated to perform the second scan (scan on the back side of the ID card). ) (S206), and the scan image (back image) data is stored in the memory 11b or the HDD 11c.

  Next, the control unit 11 (control program) checks both sides (S207). Details of this step will be described with reference to FIG. First, it is determined what is selected as the front / back confirmation element on the setting screen 18 of FIG. 4 (S401).

  When the photograph is selected as the front / back confirmation element, the first scan image and the second scan image are analyzed, and it is determined whether or not there is a photograph area in each scan image (S402). The presence or absence of this photographic region can be determined based on, for example, the color of each dot constituting the scan image, the color change, the presence or absence of a background color dot, and the like. Whether or not the photograph is a person photograph can be determined by extracting the contour of the scanned image and recognizing whether or not the extracted contour is similar to the contour of the person registered in advance. If both scanned images have a photo area (S403: Yes), or if both scanned images do not have a photo area (S404: Yes), the object is considered not an ID card. The result is NG (S406). On the other hand, if any one of the scanned images has a photographic area (S403: No and S404: No), the object is considered to be an ID card, so the confirmation result is OK (S405).

  When a keyword is selected as the front / back confirmation element, the first and second scan images are analyzed using a known OCR (Optical Character Reader) technique and registered in advance in each scan image. It is determined whether or not a specific keyword entered or input by the user is included (S407). If there is a specific keyword in both scanned images (S408: Yes), or if there is no specific keyword in both scanned images (S409: Yes), the object is considered to be not an ID card. The result is NG (S411). On the other hand, if there is a specific keyword in any one of the scanned images (S408: No and S409: No), it is considered that the object is an ID card, so the confirmation result is OK (S410).

  If a barcode is selected as the front / back confirmation element, the first scan image and the second scan image are analyzed to determine whether or not there is a barcode in each scan image (S412). . The presence or absence of this barcode is, for example, pattern recognition of the image, whether there is a plurality of parallel lines of the same length in the recognized pattern, whether there is a region where a plurality of rectangles are gathered, The determination can be made based on whether or not there is a specific pattern indicating a QR code (registered trademark). If both scanned images have barcodes (S413: Yes), or if both scanned images do not have barcodes (S414: Yes), the object is considered not an ID card. The result is NG (S416). On the other hand, if any one of the scanned images has a barcode (S413: No and S414: No), the object is considered to be an ID card, so the confirmation result is OK (S415).

  In FIG. 7, it is assumed that one of a photo, a specific keyword, or a barcode is selected as a front / back confirmation element, but two or more (for example, two of a photo and a specific keyword) are selected. It may be. In that case, either the scanned image has a photo, the scanned image has no photo, the scanned image has a specific keyword, or the scanned image has no specific keyword If it is true, the confirmation result is NG, and if neither is true, the confirmation result is OK.

  Returning to FIG. 5, the control unit 11 (control program) determines whether the front / back confirmation result is OK or NG (S208). If the confirmation result is OK, the control unit 11 (control program) generates a one-page image by arranging the scanned images for two times (S209), and the printing unit 16 prints the image on paper (S210). Thereafter, the process returns to S201 to copy the next ID card. On the other hand, if the confirmation result is NG, the control unit 11 (control program) displays a message such as “Please check the back side and try again from the beginning” on the display unit 13 (S211), and then returns to S202. Then, copy the ID card again.

  Here, when the front / back confirmation result is NG, the configuration is such that the process returns to S202 to perform scanning from the front side. For example, a message such as “Please set the back side” is displayed on the display unit 13 in S211. After that, the process may return to S205 and start again from the back side scan.

  Next, the operation when the ID scan mode is selected after setting for ID copy / ID scan will be described with reference to the flowchart of FIG.

[Processing in ID scan mode]
First, as in the ID copy mode, the control unit 11 (control program) displays a message such as “Please set the front side” on the display unit 13 and the image reading unit 12 displays the front side of the ID card. (S301). Then, the control unit 11 (control program) monitors the pressing of the start button (S302), and when the pressing of the start button is detected, operates the image reading unit 12 to perform the first scan (scan the surface of the ID card). (S303), and the scan image (surface image) data is stored in the memory 11b or the HDD 11c.

  Next, the control unit 11 (control program) displays a message such as “Please set the back side” on the display unit 13 and installs the back side of the ID card in the image reading unit 12 (S304). Then, the control unit 11 (control program) monitors the pressing of the start button (S305), and when the pressing of the start button is detected, operates the image reading unit 12 to perform the second scan (scan on the back side of the ID card). (S306), and the scan image (back image) data is stored in the memory 11b or the HDD 11c.

  Next, the controller 11 (control program) checks the front and back (S307). The details of this step are as shown in FIG. 7 and are the same as those in the ID copy mode, and the description thereof is omitted.

  Next, the control unit 11 (control program) determines whether the front / back confirmation result is OK or NG (S308). If the confirmation result is OK, the control unit 11 (control program) notifies the user that the ID scan has been successful by sounding a beep sound or the like (S309). Is generated (S310), and the image data is converted into a predetermined image format such as PDF (Portable Document Format) and stored in the memory 11b or the HDD 11c (S311), or the user is transmitted via the communication I / F unit 11d. To other computer devices. Thereafter, the process returns to S301, and the next ID card is scanned. On the other hand, if the confirmation result is NG, the control unit 11 (control program) notifies the user that the ID scan has failed by making a beep sound or the like (S312). Please display "on the display unit 13 (S313), and then return to S302 to scan the ID card again.

  Here, when the front / back confirmation result is NG, the configuration returns to S302 and is executed from the front side scan. For example, a message such as “Please set the back side” is displayed on the display unit 13 in S313. Then, the process may return to S305 and start again from the back side scan.

  As described above, when the image processing apparatus 10 is operated in the ID copy mode or the scan mode, the control unit 11 (control program) analyzes the first scan image and the second scan image, and both of them are analyzed. If a photo or a specific keyword or a specific mark (barcode) is included, or both do not include a photo or a specific keyword or a specific mark (barcode), the object to be copied / scanned It judges that it is not an ID card and warns the user. If only one of them contains a photo or a specific keyword or a specific mark (barcode), it is determined that the object to be copied / scanned is an ID card. Since both scanned images are output in association with each other, it is possible to easily and accurately determine that the ID card has been turned over. And de surface image and the back image can be properly associated.

  In addition, this invention is not limited to the said Example, The structure and control can be changed suitably, unless it deviates from the meaning of this invention.

  For example, in the above embodiment, the case where the front and back surfaces of the ID card are copied / scanned has been described. However, for any medium having a photo or a specific keyword or a specific mark on only one of the front and back surfaces, The control of the present invention can be similarly applied.

  Moreover, in the said Example, although the photograph, the specific keyword, and the specific mark were illustrated as an element for identifying the image of the surface of an ID card, and the image of a back surface, it included in one of the surface of a ID card, or the back surface. Any element that is not included in the other element may be used. For example, a front-side image and a back-side image may be identified using a line drawn at a specific location. Further, the front image and the back image may be identified based on the layout of each element included in the image.

  INDUSTRIAL APPLICABILITY The present invention can be used for an image processing apparatus that can read the front and back surfaces of a medium and output the front image and the back image in association with each other.
