  FIG. 10 is a sequence diagram showing an operation example of the document management server 10 and the image input device 20.

  As shown in FIG. 10, the image input device 20 inputs a document image (step S10). The control unit 21 of the image input device 20 captures an image of a document by the image capturing unit 26 and inputs the document image. For example, when the worker steps on the image input switch, the control unit 21 captures an image of a plurality of documents arranged on the table with a digital camera.

  The control unit 21 may accept the input of the customer name of the document to be imaged. Further, the control unit 21 may receive an input of the type of each document in the document set. In addition, the control unit 21 may automatically generate a receipt number, a work number, and the like as the packet ID and the document ID, or may receive an input of the receipt number, the work number, and the like.

  Next, the image input device 20 corrects the image data (step S11). Specifically, the control unit 21 corrects the inclination or the like of the captured image data. For example, the control unit 21 detects the frame of the document in the image by image processing and corrects the inclination.

  Next, the image input device 20 determines whether or not the image is properly captured (step S12). Specifically, the control unit 21 detects a fold or a chip of the document, and when the degree of the fold or the ratio of the chip is equal to or more than a predetermined value, it is determined that the image is not properly captured. Further, even when the number of captured images is not the specified number, the control unit 21 determines that the image has not been properly captured. The control unit 21 displays the imaged document on the screen of the output unit 24, the operator confirms the input, and the control unit 21 inputs whether or not the image is properly captured. It may be accepted via.

  When the image is properly captured (step S12; YES), the image input device 20 transmits the captured image (step S13). Specifically, the control unit 21 transmits the image data to the document management server 10 via the communication unit 23.

  When the image is not properly captured (step S12; NO), the image input device 20 returns to the process of step S10.

  Next, the image input device 20 erases the image data (step S14). Specifically, the control unit 21 deletes the captured image data from the storage unit 22, the RAM or the like after transmitting the image data.

  Next, the document management server 10 registers the image (step S15). Specifically, the control unit 11 receives the image data from the image input device 20. The control unit 11 stores the received image data in the image database 12c.

  Next, the document management server 10 generates an examination image (step S16). Specifically, the control unit 11 generates an examination image and stores the examination image in the image database 12c by a later-described examination image generation subroutine.

Specifically, the control unit 11 refers to the registration database 12a, acquires the required security level, the type of the description information, the size of the character string of the description information, and the type and shape of the description information. Specify the size of. It should be noted that the control unit 11 may accept input of information on the security level, the type of the description information, and the size of the character string of the description information from the operation unit 15. The control unit 11 may identify the type of description information or the size of the shape by image recognition.

  The document management server 10 functions as an example of a description type specifying unit that specifies the type of description information described on the object. The document management server 10 functions as an example of a shape specifying unit that specifies the size of the shape of the description information.

  The document management server 10 may specify the type of the description information described in the target object based on the type of the target object. For example, when the target object is a resident's card all-entry format, the type of the described information may be characters. If the object is a questionnaire, there are many options, and therefore the type of information described in the item may be a selection mark. When the target object is a questionnaire having a selection field and a free description field, the type of the description information may be specified by the format information of the target object.

  Next, the document management server 10 determines the number of layers of the layer image based on the security level such as the type of written information (step S21). Specifically, the control unit 11 determines the number of layers of the layer image by referring to the discrimination difficulty database 12f based on the security level, the type of written information, and the size of the character string of the written information. For example, when the type of the described information is a horizontal writing character string and the level of visibility is required to be a security level in which the described information is identifiable and “Δ”, as shown in FIG. 7A. The control unit 11 determines that the number of layers is 2. The type of written information is a circle in a horizontal questionnaire, the level of visibility is a security level where the written information is identifiable and "x" is required, and the font size when generating a layer image is " In the case of “large”, the control unit 11 determines that the number of layers is 4, as shown in FIG. 7B.

  When the type of the described information is different for each described information, or when the required security level is different for each described information, the control unit 11 determines, based on the security level, the type of the described information, and the size of the character string of the described information, The number of layers of the layer image is determined for each description information by referring to the discrimination difficulty database 12f.

  The document management server 10 requests the number of layers of the superimposition pattern to be used in the case of covering the description information with a plurality of the superposition patterns for the identified type of the description information and the description information. It functions as an example of a superimposing pattern layer number determining unit that determines the number of superimposing pattern layers. The document management server 10 further functions as an example of a superimposition pattern layer number determining unit that determines the number of layers of the superimposition pattern according to the size of the shape of the description information.

  When determining the number of layers of the layer image, the control unit 11 may accept input of the font size when generating the layer image. The size of the font used to generate the layer image may be predetermined or may be the same as the size of the character string of the description information.

  Next, the document management server 10 generates a layer image which is an example of a superposition pattern (step S22). For example, the control unit 11 generates the layer images for the determined number of layers from the random character string. The control unit 11 may generate as many layer images as the determined number of layers from the random character string according to each description information.

  The document management server 10 has a void and functions as an example of a superimposition pattern generation unit that generates a plurality of superposition patterns by covering the above described information.

  As shown in FIGS. 12A to 12D, the control unit 11 generates a layer image so that a character string including alphanumeric characters, special symbols, etc., which is an example of a symbol, is filled in a predetermined frame. The layer image may be a character string in which the font size is changed as shown in FIG. 12B, vertical writing is performed as shown in FIG. 12C, or characters are turned upside down as shown in FIG. 12D. Further, the font of a character, which is an example of a symbol, may be changed. The layer image may be a mosaic image. The layer image may have a certain void.

  Here, as an example in which the superimposition pattern is doubly superposed, there is an image superposition pattern as shown in FIG. 13A in which the layer image of FIG. 12A and the layer image of FIG. 12B are superposed. As an example of superimposing the superimposing patterns in three layers, an image as shown in FIG. 13B in which the superimposing image of FIG. 13A and the layer image of FIG. 12C are superimposed (that is, the layer images of FIGS. 12A to 12C are superimposed A pattern for superimposing an image). Further, as an example in which the superimposition pattern is superimposed four times, an image as shown in FIG. 13C in which the superimposition image of FIG. 13B and the layer image of FIG. 12D are superposed (that is, the layer images of FIGS. 12A to 12D are A pattern for superimposition of (superimposed images) may be mentioned.

  Next, the document management server 10 superimposes and displays the layer image on the image of the document (step S23). Specifically, the control unit 11 causes the output unit 14 to display the image of the document captured by the image input device 20 with the layer image of the determined number of layers in an overlapping manner. More specifically, the control unit 11 refers to the registration database 12a, and according to the security level set in each item of the document, the description information of each item includes the layer image of the determined number of layers. , Is displayed so as to be overlapped so as to cover each described information. At this time, as shown in FIG. 14, the layer image is not superimposed on the portion that does not need to be kept secret. Further, as shown in FIG. 14, the control unit 11 may superimpose a layer image on a part of the description information. For example, the prefecture of the address does not have to be hidden.

  The document management server 10 functions as an example of a visibility adjusting unit that adjusts the visibility of the description information by covering the description information with the overlapping pattern having the determined number of layers.

  As shown in FIG. 14, in the description of the name, when the type of the description information is a character and the visibility is at a low level (a level at which flicker can be prevented), as shown in FIG. 7A, the number of layers is It becomes 1. As shown in FIG. 14, the description of the name is hindered by the visibility of one layer image in the font.

  As shown in FIG. 14, the gender description has a check mark as the type of the description information, a small level of hindrance to visibility, and the font size of the layer image is “small font”. As shown in, the number of layers is 1 to 4. As shown in FIG. 14, the description of sex is hindered by the visibility of one layer image in the font.

  As shown in FIG. 14, in the description of the address, if the type of the description information is a character and the hindrance of visibility is at a small level (a level at which flicker can be prevented), as shown in FIG. 7A, the number of layers is It becomes 1. As shown in FIG. 14, the address description is impaired in visibility with one layer image having a small font.

  Here, regarding the method of superimposing display, for example, the control unit 11 binarizes the layer image, cuts out the white portion, and extracts only the pattern of the portion such as black. Next, the control unit 11 superimposes the images of the patterns of the extracted parts to generate a combined image. The background image other than the pattern of the black portion may be made transparent or transparent, or the position information of the pixels of the pattern of the black portion may be extracted. By OCR (Optical Character Recognition), only the pattern of the black portion or the like may be extracted. The recognition rate of the OCR may be low because it is sufficient if it can be converted into some code information.

  Next, the document management server 10 receives the input of the determined visibility level (step S24). The level of visibility that the operator sees and determines the superimposed image displayed on the output unit 14 is input via the operation unit 15. The visibility level may be input for each item of the description information. Also, different visibility levels (or different security levels) may be set for each item.

  Note that, as shown in FIG. 14, the operator may see the superimposed image in which the layer image is superimposed on the description information while the entire document is visible. Further, as shown in FIG. 15, an opening may be provided so that an operator can see only a predetermined item (for example, a name item). As shown in FIG. 15, a layer image of a level at which information described other than the opening can be understood at a glance (for example, item of birth date, item of gender), layer image of indistinguishable level (for example, address The visibility may be hindered by the items). Furthermore, a layer image may be superimposed on the description information of the opening. An image in which a layer image is superimposed on the description information divided for each item may be shown to the operator.

  As shown in FIG. 15, the date of birth item and the item of gender are such that the type of description information is a character, and if the hindrance of visibility is at a low level, as shown in FIG. 7A, the number of layers is It becomes 1.

  As shown in FIG. 15, in the address item, if the type of the description information is a character and the level is indistinguishable, the number of layers is three or more as shown in FIG. 7A.

  Next, the document management server 10 determines whether or not the level of visibility is appropriate (step S25). The control unit 11 compares the input visibility level with the security level set for the item, and determines whether the level is within an appropriate range. For example, when the level of visibility that can be seen by gazing is an appropriate level and the determination result is an undeterminable level, the control unit 11 determines that the visibility is low. When the level of visibility that can be seen by gazing is an appropriate level and the determination result is a level that can be seen without gazing, the control unit 11 determines that visibility is high.

  The control unit 11 may calculate the porosity from the histogram of the pixels of the combined image and determine whether the porosity is within a predetermined range. Further, in step S24, the input of the determination result for the level of visibility may be accepted, and it may be determined whether or not it is appropriate according to the determination result.

  When the level of visibility is appropriate (step S25; YES), the document management server 10 stores the examination image (step S26). Specifically, the control unit 11 stores the examination image in which the layer image is superimposed on the image of the document in the image database 12c.

  When the level of visibility is not appropriate (step S25; NO), the document management server 10 adjusts the layer image (step S27).

  For example, when the visibility exceeds the upper limit, the document management server 10 adds one layer image. Specifically, the control unit 11 further superimposes one layer image on the superimposed image. The control unit 11 may newly generate a layer image and superimpose it.

  If the visibility does not exceed the upper limit, the document management server 10 removes one layer image. Specifically, the control unit 11 removes any of the superimposed layer images. The information of the original superimposed image and the superimposed certain layer image is cached in the storage unit 12 or the RAM until the superimposed image having an appropriate level of visibility is generated.

  After one layer image is added or removed, the control unit 11 displays a new superimposed image in step S23. The control unit 11 repeats the processing from step S23 to step S27 until the level of visibility becomes appropriate. In step S21, the number of layers of the layer image is determined according to the type of the description information and the like, so the number of repetitions of steps S23 to S27 is reduced.

  The document management server 10 may omit steps S24 to S25 and step 27.

  Note that, as shown in FIG. 15, the control unit 11 may leave a portion to be collated according to the operator and hinder the visibility of other portions. You can concentrate on the matching points and work. Compared to the case of completely filling with black, the contrast with the filled area becomes weaker, and it is easier on the eyes.

  Note that the examination image may be generated not by the document management server 10 that manages documents but by a terminal device for display adjustment.

  Further, in the generation of the examination image, the document management server 10 may superimpose a predetermined number of layer images on the image of the document based on the level of visibility required for the item. That is, instead of steps S21 to S26, the document management server 10 applies a layer image of a predetermined number of layers based on the level of visibility required for the item, and generates an examination image.

  In step S21, the document management server 10 may print on paper or the like by the output unit 14. In particular, the document management server 10 may print and accept the determination of the level of visibility from the operator who views the printed matter for confirmation before storing in step S26.

(2.3 Operation Example of Management Server and Collation Terminal Device)
Next, an operation example of the management server and the matching terminal device will be described with reference to FIG.

  FIG. 16 is a sequence diagram showing an operation example of the document management server 10 and the collation terminal device 30.

  As shown in FIG. 16, the verification terminal device 30 receives an input of worker information (step S30). Specifically, the control unit 31 of the verification terminal device 30 receives the login ID and the password from the operation unit 35 as the worker information. The control unit 31 may receive the worker information from the IC card carried by the worker or the code printed on the name tag by the reader. The control unit 31 sends the request for the examination image for examination to the document management server 10 together with the worker information.

  Next, the document management server 10 identifies the level of the worker (step S31). Specifically, the control unit 11 refers to the worker database 12b and specifies the level of the worker based on the worker ID corresponding to the worker information.

  Next, the document management server 10 transmits the examination image according to the level (step S32). Specifically, the control unit 11 refers to the registration database 12a for the item difficulty level and identifies the item according to the level. The control unit 11 refers to the image database 12c and extracts the examination image corresponding to the specified item. For example, the control unit 11 extracts a sex examination image for a beginner "C" level worker and an address examination for an advanced "A" level worker. Extract the image.

  The examination image corresponding to the item to be specified is, for example, as shown in FIG. 15, a layer image at a glance level at which description information other than the opening is provided at a position corresponding to the item to be specified, or a level at which the user can gaze at the level. It is an image in which the visibility is hindered by the layer image of, the layer image of an unidentifiable level, and the like. Note that an opening may be provided at a position corresponding to the item to be specified, and the layer images of the number of layers corresponding to the required security level may be further superimposed.

  At the output unit 34 of the collation terminal device 30, the control unit 11 performs the examination together with the packaging ID and the document ID so that the examination image corresponding to the item of another document is displayed for the item of one document. The image for use is transmitted to the matching terminal device 30 that has made the request. The control unit 11 transmits the examination image to each collation terminal device 30 so that the level of the worker and the difficulty level of the item match for each item.

  Next, the matching terminal device 30 displays the examination image (step S33). For example, the control unit 31 displays, on the screen of the output unit 34, an examination image corresponding to the item of the name as shown in FIG. 15 and an examination image in which the document of the contract has an opening in the item of the name. Are displayed side by side and the button for the matching result is displayed.

  Next, the collation terminal device 30 receives the input of the examination work (step S34). The operator performs collation, and when the collation result is correct, the operation unit 35 selects the OK button, and when the collation result is not correct, the NG button is selected.

  Next, the verification terminal device 30 transmits the work result (step S35). Specifically, the control unit 31, through the communication unit 33, as a work result, which is an example of a collation result, a worker ID, a packaging bag ID, an item ID, an examination result, selection information selected in a document, and the like, It is transmitted to the document management server 10.

  Next, the document management server 10 combines the work results (step S36). Specifically, the control unit 11 receives the work result from each collation terminal device 30. The control unit 11 stores the work result received from each collation terminal device 30 in the work result database 12d for each packaging bag ID and item ID. When the databases are organized by wrapping bag ID and item ID, the work results are combined. If not classified, the control unit 11 searches the work results based on the packaging ID and the item ID, and integrates the work results.

  Next, the document management server 10 registers the examination result (step S37). Specifically, the control unit 11 refers to the work result database 12d, searches the work result based on the packaging ID, collects appropriate / unsuitable information from the work result, and outputs the examination result to the examination result database 12e. Remember.

  When the collation work is completed for all items, the document confirmation work for returning the documents is performed. In the event that a document defect or missing examination result is found, information such as the package ID that reads the code on the front page of the document set to check the work history from the terminal device for collating the returned documents Is transmitted to the document management server 10.

  The document management server 10 refers to the work result database 12d, extracts the work result based on the packet ID and transmits it to the terminal device for collation work.

  As described above, according to the present embodiment, the description information is covered and partially hidden with the number of layers determined according to the type of the description information described on the object and the level of visibility required for the description information. A layer image (an example of a pattern for superimposition) can be used in an overlapping manner to adjust the level of visibility of the written information to meet the request.

  Moreover, since the number of layers of the superimposition pattern is determined according to the type of the description information and the level of visibility required for the description information, the superposition pattern can be easily determined. That is, the number of repetitions of the processing from step S23 to step S27 is reduced.

  In addition, by superimposing the superimposition pattern to the extent that the operator cannot easily recognize it and hindering the visibility of personal information, it is possible to prevent information leakage based on the memory of the operator.

  Also, in black painting and image division, if the control of the set area is wrong, the worker cannot process the data, but if it can be seen by staring, the work can be done on the spot without returning the previous process. Can proceed.

  Further, by adding and removing the superimposed pattern for superimposition, it is possible to increase the number of superimposition patterns for those requiring high security and decrease the number of superimposition patterns for those with low security to improve work efficiency. .

  Further, when the size of the shape of the description information is specified and the number of layers of the pattern for superimposition is determined according to the size of the shape of the description information, a more appropriate superimposition is performed according to the size of the shape of the description information. The number of layers of the application pattern can be determined.

  Further, when the type of the description information written on the target object is specified based on the type of the target object, it is possible to determine a more appropriate number of layers of the superimposition pattern according to the target object.

  In addition, when there are different types of written information in the multiple written information on the object, the type of written information is specified for each written information, and the type of each written information and the visibility required for each written information When determining the number of layers of the pattern for superimposition according to the level of, and adjusting the visibility of each description information, the visibility that matches the level of visibility of each description information according to the type of each description information Can be adjusted.

  When the pattern for superimposition is a pattern in which the symbols are arranged, when the pattern for superimposition is an image in which the symbols are arranged, the symbols are noticeable, and at first glance, it becomes more difficult to read.

  When different visibility levels are set for multiple pieces of description information written in a document (an example of an object), a superimposition pattern is selected according to the visibility level set for each description information. However, if the visibility of each description information is adjusted, the visibility can be adjusted for each description information while the positional relationship of the description information of the document can be grasped.

  When the visibility when the pattern for superimposition is superimposed on the description information is determined and the pattern for superimposition is selected based on the determination of the visibility, the level of visibility matched to the description information can be set accurately. In particular, when the determination result made by the worker is reflected, the worker can finely adjust the visibility level.

  When the object is a document in which the item contents are described according to a predetermined format, the visibility can be adjusted according to the item contents of the document.

(Modification of the object that hinders visibility)
Next, as a modified example of the object that impairs visibility, a case where the document is a questionnaire will be described with reference to FIGS. 17A and 17B.

  As shown in FIG. 17A, regarding the employee number, name, and affiliation description, if the type of the description information is a character and visibility is at a low level (a level that can prevent glare), as shown in FIG. 7A. In addition, the number of layers becomes one. As shown in FIG. 17A, the description of the employee number, name, and affiliation is hindered by the visibility of one layer image with a small font.

  As shown in FIG. 17A, in the selection result of the questionnaire, the type of the described information is filled with a circle, the visibility hindrance is at a middle level (a level that can be discriminated by mimicry), and the layer image font When the size is “in the font”, the number of layers is 4, as shown in FIG. 7B. As shown in FIG. 17A, the result of selection of the questionnaire options is that the visibility is hindered by the four layer images in the font.

  As shown in FIG. 17A, in the answer column in which the disease name or the like is described, the type of the description information is text, the visibility is greatly impaired (invisible level), and the font size of the layer image is When "in the font", as shown in FIG. 17A, in the answer column in which the disease name and the like are described, the visibility is hindered by three layer images of small font.

  Note that the questionnaire number, the type indicating the questionnaire regarding what, the implementation date, and the question content may not be superimposed on the superimposing pattern if there is no problem even if the operator visually recognizes it.

  As shown in FIG. 17B, regarding the employee number, name, and affiliation description, assuming that the type of the description information is a character and the visibility hindrance is at a large level (invisible level), as shown in FIG. 7A. In addition, the number of layers is 3 or more. As shown in FIG. 17A, the description of the employee number, name, and affiliation is impaired in visibility when the number of layer images of a small font is 3 or more.

  As shown in FIG. 17B, in the selection result of the questionnaire, the type of the described information is the ○ mark, the level of visibility is small (flicker prevention level), and the font size of the layer image is small. When "is in the font", the number of layers becomes 1 to 3, as shown in FIG. 7B. As shown in FIG. 17B, the result of selection of the questionnaire options is that the visibility is hindered by one layer image in the font.
