  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment described below is an embodiment when the present invention is applied to a document management system.

[1. Document management system configuration and function overview]
(1.1 Structure and function of document management system)
First, the configuration and outline function of a document management system according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic diagram illustrating a schematic configuration example of a document management system 1 according to the present embodiment. 2 and 3 are schematic views showing examples of documents.

  As shown in FIG. 1, a document management system 1 includes a document management server 10 that manages document information relating to a document (an example of an object), an image input device 20 that captures an image of the document and captures image data, and a document And a collation terminal device 30 for collating items.

  The document management server 10, which is an example of a display adjustment device, generates a superposition pattern that has a gap and covers the description information described in the document. The document management server 10 covers the description information with the generated superposition pattern and adjusts the visibility of the description information. The document management server 10 manages work in the image input device 20 and the collation terminal device 30.

  The image input device 20 captures an image of a document deposited from a customer.

  The collation terminal device 30 displays an image of a document for collation and examination. The verification terminal device 30 is installed according to each worker.

  The document management server 10, the image input device 20, and the collation terminal device 30 can exchange data with each other via the network 3 using, for example, TCP / IP as a communication protocol. The network 3 is constructed by, for example, a local area network, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network, and a gateway.

  The document is, for example, a questionnaire in which application documents such as contracts and responses are written. In addition, the documents for confirming the identity will include a resident's card, driver's license, family register card, health insurance card, passport, and receipt (for example, a receipt for utilities such as electricity and gas). ), Copy of register book, invoice.

  The target object may be not only flat paper and plastic but also a three-dimensional shape, and it is sufficient that readable information is described on the surface of the target object. As an example of the object, a boarding ticket or a transfer ribbon may be used.

  Also, as an example of document information, document image data, image data in which the level of visibility of the description information described in the document is adjusted, text data created from the image data, delivery data for delivery to the customer Electronic data such as

  Here, the visibility level is, for example, four levels such as a level at which visibility is not hindered, a level that can be understood at a glance, a level that can be understood by gaze (a level that cannot be understood at a glance), and a level that cannot be distinguished. It is. Note that the level may be further finely divided. For example, there are a level that can be found in an average of 1 second, a level that can be seen in an average of 3 seconds, a level that can be seen in an average of 5 seconds, a level that can be seen in an average of 10 seconds, and a level that can be seen in an average of 30 seconds or more. Further, the visibility level may be divided according to the void ratio of the overlapping superposition patterns. The level of visibility corresponds to a visual recognition inhibition level that inhibits visual recognition.

  Examples of document types include contracts, resident cards, and licenses. Further, the types of documents are classified according to the format of the contract for each customer in the case of a contract, and according to the format of each municipality in the case of a resident's card.

  As shown in FIG. 2, when the document is a contract, the contract details, name, address, telephone number, etc. are written on the surface of the document. Examples of the common area C of contracts of the same format include contract contents, name items, address items, telephone number items, seal stamp items (not shown), and the like. The non-common area NC of the contract includes personal information such as name, address, and telephone number. The common area is a common format portion common to documents of the same format. The non-common area is a different part for each applicant regarding documents of the same format.

  As shown in FIG. 3, when the document is a resident's card, the name of the municipality, address, name, date of birth, sex, etc. are written on the surface of the document. As common area of resident's card of form of a certain municipality (an example of a prescribed form according to the document), the name of the document, the name of the municipality, the address item, the name item, the date of birth, the item of gender, etc. It is done. Non-common areas for resident cards include personal information such as address, name, date of birth, and gender. If the document is a resident's card, the format differs depending on the municipality.

  The documents to be checked are sent as a plurality of documents related to the contract and the document for verifying the identity. Here, the plurality of related documents are a plurality of documents related to one individual or one corporation. At least two or more documents relating to the same individual or the same corporation. For example, application documents such as contracts, documents for confirming the identity of individuals or corporations (resident card, license, family register card, health insurance card, passport, receipt), documents such as invoices, etc. There are at least two documents. Examples of related documents include, for example, a combination of a contract, a resident card, and a license, a combination of a contract, a resident card, and a passport, an application document, and a combination of a health insurance card, an application document, A combination of receipts, contracts, and transcripts. These related documents are sent, for example, in an envelope containing a set of documents.

  The non-common area where the name, address, etc. are described is an example of the description area. Moreover, the described content is an example of description information. Information described for the name item, address item, telephone number item, seal stamp item, date of birth item, gender item, and the like is the description information of the document. The information described in each of these items is a single description information.

  A security level is set for each item. The security level for each item is classified according to the most important information, important information, confidential information, and the like.

  The level of visibility may correspond to the security level. For items with the highest security level, the level of visibility is lowered, such as an indistinguishable level. For items with a medium security level, set the level of visibility to be understood by staring. For items with a low security level, the visibility level should be understood without staring.

  Also, in the work result database 12d, the worker ID of the worker who collated the item, the document ID of the document used for collation, and which part of the document was used for collation in association with the packaging ID and item ID. Such selection information is stored.

  The examination result database 12e stores the worker ID and examination result of the worker who collated the items in association with the packaging ID and the item ID. The examination result is, for example, a collation result indicating whether the contents described in the set documents are the same, or data indicating whether or not there is a description. The examination result database 12e may store text data read from a resident card or the like.

  It may be managed by the same database of the same document management server 10, or each database may be stored in a database of another management server.

  The storage unit 12 may store various programs such as an operating system and a server program. Note that the various programs may be acquired from another server or the like via the network 3, or may be recorded on a recording medium and read via a drive device.

  The communication unit 13 is connected to the network 3 and controls communication with the image input device 20 and the verification terminal device 30.

[2. Operation of document management system]
Next, the operation of the document management system according to one embodiment of the present invention will be described with reference to the drawings.

(2.1 Examples of operations of document management server and image input device)
An operation example of the document management server and the image input apparatus will be described with reference to FIG.

  FIG. 9 is a sequence diagram illustrating an operation example of the document management server 10 and the image input device 20.

  As shown in FIG. 9, the image input device 20 inputs a document image (step S10). The control unit 21 of the image input device 20 captures a document with the imaging unit 26 and inputs a document image. For example, when an operator steps on an image input switch, the control unit 21 images a digital camera with a plurality of documents arranged in a table.

  Note that the control unit 21 may accept input of a customer name of a document to be imaged. Further, the control unit 21 may accept an input of the type of each document in the document set. Further, the control unit 21 may automatically generate a reception number, a work number, or the like as the packaging ID and document ID, or may receive an input of a reception number, a work number, or the like.

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

  Next, the image input device 20 determines whether or not an image has been appropriately captured (step S12). Specifically, the control unit 21 detects the folding or chipping of the document, and determines that the image is not properly captured when the degree of folding or the ratio of the chipping is a predetermined value or more. Further, even when the number of captured documents is not a specified number, the control unit 21 determines that an image is not properly captured. Note that the control unit 21 displays the captured document on the screen of the output unit 24, the operator confirms, and the control unit 21 inputs an input as to whether or not the image is properly captured. You may accept via.

  When the image is appropriately captured (step S12; YES), the image input device 20 transmits the captured image (step S13). Specifically, the control unit 21 transmits 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 deletes the image data (step S14). Specifically, after transmitting the image data, the control unit 21 erases the image data captured from the storage unit 22 or the RAM.

  Next, the document management server 10 registers an image (step S15). Specifically, the control unit 11 receives 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 a screening image by a screening image generation subroutine described later, and stores the screening image in the image database 12c.

(2.2 Subroutine for generating image for examination)
Next, the examination image generation subroutine will be described with reference to FIGS.

  FIG. 10 is a flowchart showing a screening image generation subroutine. 11A to 11D are schematic diagrams illustrating an example of a layer image. FIG. 12A to FIG. 12C are schematic diagrams illustrating examples of superimposed layer images. FIG. 13 and FIG. 14 are schematic diagrams illustrating an example of an object whose visibility is hindered.

  As shown in FIG. 10, the document management server 10 generates a layer image that is an example of a superimposition pattern (step S20). For example, the control unit 11 generates a layer image from a random character string. As illustrated in FIGS. 11A to 11D, the control unit 11 generates a layer image so that a predetermined character string including alphanumeric characters and special symbols, which are examples of symbols, 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. 11B, the character is vertically written as shown in FIG. 11C, or the characters are turned upside down as shown in FIG. 11D. Moreover, you may change the font of the character which is an example of a symbol. The layer image may be a mosaic image. The layer image only needs to have a certain gap.

  The document management server 10 has an air gap and functions as an example of a superimposition pattern generation unit that generates a plurality of superposition patterns that cover the description information described on the object.

  Here, as an example in which the superimposition pattern is superimposed twice, there is an image superposition pattern as shown in FIG. 12A in which the layer image in FIG. 11A and the layer image in FIG. 11B are superimposed. As an example of superimposing the superposition pattern in a triple manner, the superposition image of FIG. 12A and the layer image of FIG. 11C are superposed, as shown in FIG. Image) for superimposing. Furthermore, as an example in which the superposition pattern is superimposed four times, the superposition image of FIG. 12B and the layer image of FIG. 11D are superposed, as shown in FIG. 12C (ie, the layer images of FIGS. For example, a superposed pattern).

  Next, the document management server 10 superimposes and displays the layer image on the document image (step S21). Specifically, the control unit 11 causes the output unit 14 to display a layer image superimposed on the document image captured by the image input device 20. More specifically, the control unit 11 refers to the registration database 12a and selects from among the generated layer images for the description information of each item according to the security level set for each item of the document. One layer image is superimposed and displayed so as to cover the description information. At this time, as shown in FIG. 13, the layer image is not superimposed on a portion that does not need to be concealed. Moreover, as shown in FIG. 13, the control part 11 may superimpose a layer image on a part of description information. For example, the prefecture of the address may not be hidden.

Here, for example, the control unit 11 binarizes the layer image, cuts out the white part, and extracts only the pattern of the part such as black. Next, the control unit 11 superimposes the extracted pattern images to generate a combined image. Note that a background image other than the black pattern or the like may be subjected to transparency or transmission processing, or pixel position information of the black pattern or the like may be extracted. Only a pattern of a black portion or the like may be extracted by OCR (Optical Character Recognition). Since some kind of code information is required, the OCR recognition rate may be low.

  Next, the document management server 10 receives an input of a visibility level (step S22). The operator views the superimposed image displayed on the output unit 14 and inputs a visibility level via the operation unit 15. A visibility level may be input for each item. Different visibility levels (or different security levels) may be set for each item.

  As shown in FIG. 13, a superimposed image obtained by superimposing a layer image on the description information may be shown to the operator while the entire document is visible. Moreover, as shown in FIG. 14, you may provide an opening part so that an operator can see only a predetermined | prescribed item (for example, item of a name). As shown in FIG. 14, the layer information of a level that can be understood at a glance (for example, a gender item), the layer image of a level that can be understood by gaze (for example, an item of birth date), discrimination, etc. Visibility may be hindered by an impossible level layer image (for example, an address item) or the like. Furthermore, a layer image may be superimposed on the description information of the opening. Moreover, you may show an operator the image which superimposed the layer image with respect to the description information divided | segmented for every item.

  Next, the document management server 10 determines whether or not the visibility level is appropriate (step S23). The control unit 11 compares the input visibility level with the security level set in the item, and determines whether or not it is in an appropriate range. For example, when the level of visibility that can be understood by staring is an appropriate level and the determination result is an indistinguishable level, the control unit 11 determines that the visibility is low. When the level of visibility that can be understood by staring is an appropriate level and the determination result is a level that can be understood without staring, the control unit 11 determines that the visibility is high.

  The document management server 10 functions as an example of a visibility determination unit that determines the visibility when the superimposition pattern is superimposed on the written information.

  Note that the control unit 11 may calculate the void ratio from the histogram of the pixels of the combined image and determine whether the void ratio is within a predetermined range. Further, in step S22, an input of a determination result for the visibility level may be received, and whether or not it is appropriate may be determined according to the determination result.

  If the visibility level is appropriate (step S23; YES), the document management server 10 stores the examination image (step S27). Specifically, the control unit 11 stores the examination image in which the layer image is superimposed on the document image in the image database 12c.

  If the visibility level is not appropriate (step S23; NO), the document management server 10 determines whether the visibility is high (step S24).

  If the visibility exceeds the upper limit (step S24; YES), the document management server 10 adds one layer image (step S25). 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 (step S24; NO), the document management server 10 removes one layer image (step S26). Specifically, the control unit 11 removes one of the superimposed layer images. Note that the information of the original superimposed image and the superimposed layer image is cached in the storage unit 12 and the RAM until a superimposed image with an appropriate visibility level is generated.

  After one layer image is added or removed, the control unit 11 displays a new superimposed image in step S21. The control unit 11 repeats the processing from step S21 to step S26 until the appropriate visibility level is reached. Finally, a superimposition pattern corresponding to the level of visibility required for the description information is selected. Moreover, description information is covered with the selected superimposition pattern, and the visibility of description information is adjusted.

  The document management server 10 selects at least one superimposition pattern to be used in an overlapping manner when covering the description information with a plurality of superimposition patterns according to the level of visibility required for the description information. It functions as an example of a superimposition pattern selection means. The document management server 10 functions as an example of a superimposing pattern selection unit that selects the superimposing pattern based on the visibility determination.

  The document management server 10 functions as an example of a visibility adjusting unit that covers the description information with the selected superposition pattern and adjusts the visibility of the description information.

  In addition, as shown in FIG. 14, the control part 11 may leave the location which collates according to an operator, and may impair the visibility of another part. You can concentrate on the verification location and work. Compared with the case of completely painting with black, the contrast with the painted area becomes weaker and the eyes become gentler.

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

  Further, in generating the examination image, the document management server 10 may superimpose a predetermined number of layer images on the document image 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 visibility level required for the item, and generates an examination image.

  In step S <b> 21, the document management server 10 may print on paper or the like by the output unit 14. In particular, before storing in step S24, the document management server 10 may print and accept the determination of the visibility level from the worker who viewed the printed matter for confirmation.

(2.3 Example of operation of management server and verification terminal device)
Next, operation examples of the management server and the verification terminal device will be described with reference to FIG.

  FIG. 15 is a sequence diagram illustrating an operation example of the document management server 10 and the verification terminal device 30.

  As shown in FIG. 15, the collation terminal device 30 receives input of worker information (step S30). Specifically, the control unit 31 of the verification terminal device 30 receives a login ID and a password from the operation unit 35 as worker information. Note that the control unit 31 may receive worker information from an IC card carried by the worker or a code printed on a name tag by a reader. The control unit 31 transmits a request for an examination image for examination together with the worker information to the document management server 10.

  Next, the document management server 10 specifies 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 an examination image corresponding to the level (step S32). Specifically, the control unit 11 refers to the registration database 12a for the difficulty level of the item, and specifies an item according to the level. The control unit 11 refers to the image database 12c and extracts a screening image corresponding to the item to be specified. For example, the control unit 11 extracts a gender examination image for the beginner “C” level worker, and examines an address for the advanced “A” level worker. Extract images.

  For example, as shown in FIG. 14, the examination image corresponding to the item to be specified is a layer image at a level where the description information other than the opening can be understood at a glance at a location corresponding to the item to be specified. This is an image in which visibility is hindered by a layer image, a layer image of an indistinguishable level, or the like. It should be noted that an opening may be provided at a location corresponding to the item to be specified, and the number of layer images corresponding to the required security level may be further superimposed.

  In the output unit 34 of the collation terminal device 30, the control unit 11 examines together with the package ID and the document ID so that the examination image corresponding to the item of the other document is displayed for the item of one document. The image for use is transmitted to the collation terminal device 30 that requested it. The control unit 11 transmits the examination image to each verification terminal device 30 so that the level of the worker matches the difficulty level of the item for each item.

  Next, the collation terminal device 30 displays an 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 name item as shown in FIG. 14, and an examination image in which an opening is provided in the name item in the contract document. Are displayed side-by-side, and a button for the matching result is displayed.

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

  Next, the collation terminal device 30 transmits a work result (step S35). Specifically, the control unit 31 provides, via the communication unit 33, a worker ID, a bag ID, an item ID, an examination result, selection information selected in the document, and the like as a work result that is an example of a matching result. It transmits 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 verification terminal device 30. The control part 11 memorize | stores the work result received from each collation terminal device 30 in work result database 12d for every packaging ID and item ID. When the database is organized by wrapping ID and item ID, the work results are combined as a result. When the items are not sorted and arranged, the control unit 11 searches for the work result 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 obtains the examination result as the examination result database 12e. To remember.

  After all items have been collated, the document is checked for document return. Information such as packaging ID that read the code on the front page of the set of documents to confirm the work history from the terminal device for collation of returned documents when incomplete documents, missing examination results, etc. are found Is transmitted to the document management server 10.

The document management server 10 refers to the work result database 12d, and based on the packaging ID,
The work result is extracted and transmitted to the terminal device for collation work.

  As described above, according to this embodiment, the layer information (an example of a superimposition pattern) that covers and partially hides the description information described in the document is used, and the visibility of the description information depends on the number of layer images that are overlapped. You can adjust the level.

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

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

  Also, by adding and subtracting the superimposed superimposition patterns, it is possible to increase the number of superimpositions of superimposition patterns for those requiring high security, and to increase the work efficiency by reducing the number of superpositions of superimposition patterns for those with low security. .

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

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

  When the visibility when the superimposition pattern is superimposed on the description information is determined and the superimposition pattern is selected based on the determination of the visibility, the level of visibility according to the description information can be set accurately. In particular, when reflecting the determination result made by a human, the visibility level can be finely adjusted by the human.

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

(3.1 Modification of superimposed layer image)
Next, a modified example of the superimposed layer image will be described with reference to FIGS. 16 and 17.

  As illustrated in FIG. 16, the document management server 10 may superimpose layer images having the same pattern while shifting the positions when layer images are superimposed.

  Further, as shown in FIG. 17, a plurality of layer images having different sizes covering the description information may be used in a superimposed manner. For example, as shown in FIG. 17, a layer image in which the central portion is superimposed on three layers, a periphery of the layer image is superimposed on two layers, and a periphery is a layer image on one layer.

  In this case, it is possible to generate a superimposition pattern having a difference in visibility level, such as where the visibility level is partially high or low in the superposition pattern. In addition, even when a description area is determined for each description information and the description protrudes, it is possible to adjust the visibility while minimizing the influence on other description areas. When the degree of layer image superimposition is high in the central part and low in the peripheral part, fluctuations in the description area can be absorbed. That is, the superimposition can be made invisible in the central part, and the superimposition can be reduced in the peripheral part so that the operator can read it even when the description area is shifted.

(3.2 Modification of the object that obstructs visibility)
Next, a modified example of the target that hinders visibility will be described with reference to FIGS.

  As illustrated in FIG. 18, there is a description mistake, which may be erased with a line and the description information may be described in the margin. As shown in FIG. 17, a layer image in which a plurality of overlapping patterns having different sizes covering the description information may be applied to the description portion.

  Next, the case where the document is a questionnaire will be described with reference to FIG.

  As shown in FIG. 19A, in the description of the employee number, name, and affiliation, the visibility may be inhibited by a superimposition pattern at a small level of inhibition of visibility (a level that can prevent flickering). As a result of the selection of the questionnaire options, the visibility may be hindered by a superimposition pattern, while the visibility hindrance is at a medium level (a level that can be read by pseudovision). In the answer column in which the disease name and the like are described, the visibility may be disturbed by a superimposition pattern, with the visibility being at a large level (not visible).

  In addition, the pattern for superimposition does not need to be superimposed on the questionnaire number, the type indicating what the questionnaire is about, the implementation date, and the question content when there is no problem even if the operator visually recognizes the problem.

  As shown in FIG. 19B, the visibility of the respondent name, employee number, and the like may be hindered by the superimposition pattern with a high level of visibility hindrance. As a result of selecting the questionnaire options, the visibility may be reduced to a low level (flicker prevention level), and the visibility may be inhibited by the superimposition pattern.

  As shown in FIG. 19C, the visibility may be hindered by the superimposition pattern for all the described portions indistinguishable.

  As illustrated in FIG. 19D, for each piece of written information, the visibility may be hindered by the superimposition pattern in an indistinguishable manner with respect to all the written portions. Furthermore, visibility may be inhibited for each option.

  Next, the case where the object is a ticket such as a limited number of boarding tickets will be described with reference to FIG.

  As shown in FIG. 20A, the visibility of an unused boarding pass is not hindered.

  As illustrated in FIG. 20B, when the use section is described after being used once, the visibility may be hindered by the overlapping pattern to some extent.

  As shown in FIG. 20C, when the use section is described after being used twice, the superimposition pattern may be further superimposed, and the visibility may be hindered to the extent that it can be understood when staring.

  As shown in FIG. 20D, when the use section is described after being used three times, the superimposition pattern may be further superimposed, and the visibility may be hindered to the extent that it can be understood when staring well.

  As shown in FIG. 20E, when the use section is described after being used four times, a superimposition pattern may be further superimposed, and visibility may be impeded so as to be indistinguishable.

  As shown in FIG. 20F, when the boarding ticket is discarded after being used four times, the visibility may be hindered by the superimposition pattern so that the name cannot be discriminated.

  The initial ride history is not important information to know the owner's behavior, but as the ride history increases in the middle and late periods, the owner's behavior pattern can be deciphered from the ride history, as confidential information The importance of increases. On the other hand, when the boarding history is described in the ticket, it is convenient for the owner because it is possible to know where the boarding / exiting was made.

  In this application, according to the change in importance as confidential information, visibility is disturbed to a level that can be understood at a glance, visibility is inhibited to a level that can be understood by staring, or visibility to a level that can be understood if staring well. By changing the level of visibility such as hindering or hindering visibility to an indistinguishable level, the trade-off relationship between information security and convenience for the owner is solved. In addition, it can be realized by a simple printing system.

  When the description information described in the object changes, by selecting a superimposition pattern according to the level of visibility of the changed description content, and adjusting the visibility according to the changed description information, The visibility can be adjusted in accordance with the change in the written information even when the written content changes as the written content increases and increases. Further, the security level can be changed according to the change of the description information.

  Next, the case where the object is a sublimation transfer ribbon will be described with reference to FIG.

  As shown in FIG. 21A, regarding the ribbon of the portion used for describing the expenses of the patent office, the visibility may be hindered to the extent that it can be understood by staring at the two layers of layer images.

  As shown in FIG. 21B, the portion of the ribbon used for describing the opinion may be superimposed by a single layer image, and visibility may be hindered to the extent that it can be understood at a glance.

  As shown in FIG. 21C, the ribbon of the portion used in the description of the first draft of the specification is superimposed by a three-layer image, and visibility may be hindered in an unreadable manner.

  As shown in FIG. 21D, the portion of the ribbon used in the private email description may be superimposed by a single layer image and the visibility may be hindered to the extent that it can be understood at a glance.

  As shown in FIG. 21E, the ribbon of the portion used for describing the drawing may be superimposed by a three-layer image, and the visibility may be hindered in an unreadable manner.

  By further transferring the superimposition pattern to the transfer ribbon after information transfer, what kind of information was transferred from the transfer ribbon after use can be visually invisible or difficult to read. The security level can be selected at the time of information transfer.

  That is, a plurality of security levels can be mixed in one roll of transfer ribbon after use. Transfer information with a low security level can be read visually, and those with a high security level can be reproduced with the image processing equipment and superimposition patterns stored in the database. Is possible.

  In addition, when reproducing visually, depending on the security level of the information when printing the transfer ribbon, whether to make it legible at a glance (glance) level or legible at the gaze (cancer) level Can be selected. If it can be read with a flicker, it can be processed quickly, but the security level is lowered. On the other hand, it takes time to read by staring, but the security level goes up. In addition, when a gaze level superimposing pattern is used, image processing equipment and a database are unnecessary and can be easily read.

  In the case of a document that is an example of an object, the required level of visibility differs for each item such as name and address, for each worker, or for each process.

  In the case of a questionnaire that is an example of an object, the level of visibility that prevents visibility of a mark location from being disturbed by the visibility of a name or the like is different.

  In the case of a ticket, which is an example of an object, the required level of visibility varies depending on the number of uses.

  In the case of a transfer ribbon which is an example of an object, the type of document to be printed and the required level of visibility are different.

  As described above, even if the required level of visibility is different, it is possible to select the optimum number of superimposed patterns for superimposition according to the target work and application, and to adjust the level of visibility of written information.

(3.3 colored layer image)
Next, the case where the layer image is colored will be described with reference to FIGS.

22A to 22D are schematic diagrams illustrating an example of a colored layer image.
FIG. 23A to FIG. 23C are schematic diagrams illustrating examples of superimposed layer images.
FIG. 24A to FIG. 24C are schematic diagrams illustrating modifications of the target object that impairs visibility.

  As shown in FIGS. 22A to 22D, the layer image as an example of the superimposition pattern may be colored. The layer image is formed by a pattern formed with at least one color.

  FIG. 22A is a layer image in which the layer image of FIG. 11A is blue. For example, as illustrated in FIG. 22A, the control unit 11 generates a blue layer image so that a blue character string including alphanumeric characters, special symbols, and the like is filled in a predetermined frame.

  FIG. 22B is a layer image in which the layer image in FIG. 11B is red. For example, as illustrated in FIG. 2B, the control unit 11 generates a red layer image so that a red character string including alphanumeric characters, special symbols, and the like fills a predetermined frame.

  FIG. 22C is a layer image in which the layer image in FIG. 11C is green. For example, as illustrated in FIG. 22C, the control unit 11 generates a green layer image so that a predetermined character frame is filled with a green character string including alphanumeric characters and special symbols.

  FIG. 22D is a layer image in which the layer image of FIG. 11D is yellow. For example, as illustrated in FIG. 22D, the control unit 11 generates a yellow layer image so that a yellow character string including alphanumeric characters, special symbols, and the like is filled in a predetermined frame.

  Note that the color of the layer image may be changed later by image processing. The color may be a primary color or an intermediate color. Moreover, you may change a color for every character produced | generated.

  In step S20, the document management server 10 generates a colored layer image that is an example of a superimposition pattern.

  As shown in FIG. 23A, as an example in which the colored superposition pattern is superimposed twice, there is a superposition pattern in which the blue layer image in FIG. 22A and the red layer image in FIG. 22B are superimposed. As shown in FIG. 23A, when a red layer image is superimposed on a blue layer image, a part of the blue symbol disappears and a part of the red symbol is placed.

  As an example of superimposing the colored superposition patterns in a triple manner, the superposition image of FIG. 23A and the green layer image of FIG. 22C are superposed, as shown in FIG. 23B (that is, the layers of FIGS. 22A to 22C). A pattern for superimposing the image). As shown in FIG. 23B, when a green layer image is superimposed on a double superimposition image, a part of the symbol of the double superimposition image disappears and a part of the green symbol appears. become.

  Further, as an example in which the superposition pattern is superimposed four times, the superposition image of FIG. 23B and the yellow layer image of FIG. 22D are superposed, as shown in FIG. 23C (that is, the layers of FIGS. 22A to 22D). A pattern for superimposing the image). As shown in FIG. 23C, when a yellow layer image is superimposed on a triple superimposition image, a part of the symbol of the triple superimposition image disappears and a part of the yellow symbol appears. become.

  The order of superposition may be reversed. For example, the blue layer image of FIG. 22A may be superimposed on the red layer image of FIG. 22B. In this case, some of the red symbols disappear and some of the blue symbols appear. The portion where the symbols overlap may be an intermediate color (for example, purple which is a mixed color of red and blue).

  In step S20, the document management server 10 generates a layer image formed with at least one color, which is an example of a superimposition pattern.

  In step S23, when determining whether or not the level of visibility is appropriate, the color of the layer image is considered and the visibility is determined. In step S24, whether or not the visibility is high is influenced by the color of each layer image.

  For example, as shown in FIG. 24A (color), when two color layer images are superimposed on black characters in the order of blue and red, the monochrome layer image shown in FIG. 24A (black and white) is superimposed on black characters. Compared with the case, the visibility is improved.

  Also, as shown in FIG. 24B (color), when the three-color layer image is superimposed on black characters in the order of blue, red, and green (that is, for the color in FIG. 24A, Furthermore, the visibility is improved compared to the case where the black and white layer image shown in FIG. 24B (black and white) is superimposed on the black character when the green layer image is superimposed.

  Also, as shown in FIG. 24C (color), when the four color layer images are superimposed on black characters in the order of blue, red, green, and yellow (that is, for the case of the color shown in FIG. 24B). Further, when the yellow layer image is superimposed), the visibility is improved as compared with the case where the black and white layer image shown in FIG. 24C (black and white) is superimposed on the black character.

  Note that the number of color schemes and the order of color schemes listed above are merely examples, and various color schemes are possible. There are also various combinations of the color of the superimposed character and the color of the layer to be superimposed. If the color of the superimposed character and the color of the layer to be superimposed are the same or similar, the visibility deteriorates.

  As described above, the visibility can be adjusted by the color of the layer image. Although there are differences among individuals, if they are arranged in the order of high visibility, for example, the color in FIG. 24A, the color in FIG. 24B, the black and white in FIG. 24A, the color in FIG. 24C, the black and white in FIG. Further, comparing the black and white in FIG. 24B with the color in FIG. 24C, it can be seen at a glance that the color in FIG. 24C is obscured. Some people know that.

  In steps S25 and S26, the document management server 10 may determine a layer image to be added or removed based on the color of the layer image. For example, a layer image having a color different from the superimposed color is added.

  The superimposition pattern (for example, a layer image) is a pattern formed with at least one color, and at least one pattern formed with at least one color is selected according to the level of visibility required for the description information. When selecting, visibility can also be adjusted by the color of the superimposition pattern. Accordingly, the range of visibility adjustment is widened. Further, the visibility stage can be set more finely. For example, a single color (for example, black) such as the color of FIG. 24A, the color of FIG. 24B, the black and white of FIG. 24A, the color of FIG. 24C, the black and white of FIG. 24B, and the black and white of FIG. Compared with the case of only the superimposing pattern, a part of the visibility can be filled.

  The superimposition pattern is a pattern formed with one of a plurality of colors, and when the description information is covered with a plurality of superposition patterns, the superimposition pattern to be used in an overlapping manner is visually required for the description information. When at least one layer is selected based on the color of the superimposition pattern according to the level of the property, when adding one layer of the superimposition pattern or removing one layer, the color of the superimposition pattern determines the visibility. Can be adjusted.

  Furthermore, the present invention is not limited to the above embodiments. Each of the embodiments described above is an exemplification, and any configuration that has substantially the same configuration as the technical idea described in the claims of the present invention and has the same operational effects can be used. It is included in the technical scope of the present invention.
