20220407981
The present application claims priority from Japanese Patent Application Number 2021-103464, the content to which is hereby incorporated by reference into this application.
The present disclosure relates to an image output device and the like.
So as to prevent a leakage of any confidential information which a user does not want to be known to any unspecified other person and so as to reduce the cost required for such prevention, Japanese Unexamined Patent Application Publication No. 2009-177699 discloses a technology that, for any image information including input secret information, codes the secret information, and replaces the image information with coded secret information.
The technology described in the Japanese Unexamined Patent Application Publication No. 2009-177699 replaces the image information's to-be-kept-secret portion with the coded secret information, and executes a printing based on the replaced image information generated after the replacing.
In the technology described in the Japanese Unexamined Patent Application Publication No. 2009-177699, a decoder for decoding the coded secret information for each viewer environment is required for visualization of the coded secret information. Once the information or the like necessary for the decoding is acquired, the replaced image information can be decoded anytime and anywhere. Therefore, if the replaced image information is diffused together with the information necessary for the decoding, viewing by any unspecified other person could not be restricted.
In addition, the technology described in the Japanese Unexamined Patent Application Publication No. 2009-177699 is designed to reduce the cost for preventing a secret leakage by replacing the image information's to-be-kept-secret portion with the coded secret information. However, the coded secret information according to the Japanese Unexamined Patent Application Publication No. 2009-177699 does not necessarily reduce the color material consumption amount, the drawing area, or the like, and, as the case may be, causes such a problem that the increase in the amount of to-be-added information increases the color material consumption amount and the drawing area.
It is an object of the present disclosure to provide an image output device and the like that, in the case where a to-be-drawn image includes a to-be-managed image area, can facilitate the management of the image area, and can reduce any cost for the image formation in the image area or in the overall drawing area.
For solving the above problem, an image output device according to the present disclosure includes: a controller; and an image outputter, wherein the controller, when a specific area that matches a specific condition is present in a first image, stores, in a storing area, information that is based on the specific area, generates an identification code that includes access information for accessing the stored information that is based on the specific area, and outputs a second image where the specific area of the first image is replaced with an image that includes the identification code.
In addition, an image output system according to the present disclosure includes: an image output device having a controller and an image outputter; and a storage device having a storage and an outputter, wherein the controller, when a specific area that matches a specific condition is present in a first image, has the storage store information that is based on the specific area, generates an identification code that includes access information for accessing the stored information that is based on the specific area, and outputs a second image where the specific area of the first image is replaced with an image that includes the identification code, and wherein the outputter, according to an access that is based on the identification code, outputs the image included in the stored specific area.
In addition, an image outputting method according to the present disclosure includes: when a specific area that matches a specific condition is present in a first image, storing, in a storing area, information that is based on the specific area; generating an identification code that includes access information for accessing the stored information that is based on the specific area; and outputting a second image where the specific area of the first image is replaced with an image that includes the identification code.
According to the present disclosure, it is possible to provide an image output device and the like that, in the case where a to-be-drawn image includes a to-be-managed image area, can facilitate the management of the image area, and can reduce any cost for the image formation in the image area or in the overall drawing area.

The specific condition, including a specific color material consumption amount's threshold (predetermined amount), is stored in the specific condition storing area 255.
A color material amount estimating program 2511a is read out by the image processor 23 when estimating the color material amount consumed for printing out each image area included in the first image. The image processor 23 having read out the specific condition determining program 2511 compares the estimated color material consumption amount with the color material consumption amount's threshold as the specific condition read out from the specific condition storing area 255, thereby to determine whether or not the specific area matching the specific condition is present in the first image.
The specific area specific area extracting program 2513 is read out by the image processor 23 when determining that the specific area matching the specific condition is present.

In the present disclosure, the specific area is synonymous with an image area (information) that satisfies the specific condition.
The access information acquiring program 2515 is read out by the image processor 23 when the specific area is extracted from the first image. The image processor 23 having read out the access information acquiring program 2515 sends the extracted specific area to the external storage device 30, and sends a request for acquiring access information generated by the external storage device 30. In addition, the access information is for accessing the image information related to the specific area stored by the external storage device 30.

In addition, the generated second image as the document printout or document data is output from the image outputter 21, and is supplied to the terminal device 50, the user, and the like.
The authenticating program 253 is read out by the controller 11 when authenticating the external storage device 30 or the terminal device 50. The controller 11 having read out the authenticating program 253 uses the authentication information such as user ID, authentication password, and device identification ID which are not shown, and thereby authenticates the external storage device 30 or the terminal device 50.
The specific condition storing area 255 stores the specific condition including the color material consumption amount's threshold.
The specific area storing area 257 stores the specific area extracted by the image processor 23 having read out the specific area extracting program 2513.

In response to the access information acquiring request from the multifunction peripheral 10, the identification code generating program 393 is read out by the controller 31 when generating the access information. The controller 31 having read out the identification code generating program 393 images the access information including a URL (Uniform resource locator), a host name, or an IP address to access the specific area stored in the specific area storing area 395, thereby to generate the identification code. In addition, the controller 31 converts the to-be-generated identification code into a size smaller than an image size of the specific area.

Flow of Processes
1.2.1 Overall Process
Then, the overall process according to the first embodiment will be described using the sequence diagram in
First, the multifunction peripheral 10 controls the image input 19 thereby to accept the inputting of the document printout or document data and acquire the first image (step S100).
Then, the image processor 23 of the multifunction peripheral 10 reads out the image replacing program 251. When the first image includes the specific area, the image processor 23 extracts the specific area (step S110).
The image processor 23 sends the specific area to the external storage device 30 (step S120). Then, to the external storage device 30, the image processor 23 sends an identification code acquiring request as the access information (step S130).
The external storage device 30 stores the received specific area in the specific area storing area 395 (step S140). Then, the controller 31 of the external storage device 30 reads out the identification code generating program 393 thereby to generate the identification code that is based on the specific area (step S150).
The controller 31 sends the generated identification code to the multifunction peripheral 10 (step S160).
The image processor 23 of the multifunction peripheral 10 having received the identification code reads out the image generating program 2517 thereby to, in the first image, replace the image area, which corresponds to the specific area, with the received identification code, thereby to generate the second image. Then, the image processor 23 outputs the generated second image via the image outputter 21 (step S170).
When the second image is output from the multifunction peripheral 10, the controller 51 of the terminal device 50 reads out the specific area acquiring program 613. The controller 51 having read out the specific area acquiring program 613 controls the identification code input 59 thereby to acquire the identification code from the second image.
Based on the access information included in the identification code, the controller 51 sends a specific area acquiring request to the external storage device 30 (step S180).
The controller 31 of the external storage device 30 having received the specific area acquiring request reads out the specific area from the specific area storing area 395, and send the specific area to the terminal device 50 (step S190).
The controller 51 of the terminal device 50 having received the specific area from the external storage device 30 displays the received specific area on the display 53 (step S200).
1.2.2 Regarding Process of Multifunction Peripheral 10
Then, the process of the multifunction peripheral 10 will be described using the flowchart in
The image processor 23 of the multifunction peripheral 10 determines whether or not the image replacing is permitted (step S310). In this case, referring to the system setting, etc., for example, and if an item related to the image replacing is set to “allowable”, the image processor 23 can determine that the image replacing is permitted. When the first image is acquired, a user interface (not shown) to inquire the user whether or not to permit the image replacing may be displayed on the display 13. When the user permits the image replacing, the image processor 23 proceeds to the next step.
When it is determined that the image replacing is permitted, the image processor 23 reads out the image replacing program 251. Then, the image processor 23 having read out the color material amount estimating program 2511a included in the image replacing program 251 estimates the color material consumption amount that is consumed when each image area included in the first image is printed out (step S310; Yes→step S320).
By the way, the color material consumption amount can be estimated depending on (1) in the case of printing (2) or in the case of copying/scanning.
For example, (1) in the case of printing, a page description language output from a printer driver describes text (character), vector (vector data such as line and figure), and raster (image data such as photograph) separately. In principle, the image processor 23, by executing the rasterization and color conversion on an object other than the text, can estimate the color material consumption amount.
(2) When the paper document is read by the image input 19 (scanner), as in the case of copying/scanning, there is no distinction such as text/vector/raster. However, the image processor 23 separates the area into a character area, a photograph area, etc., and executes an image process that is appropriate for each; therefore, it is possible to estimate, in the same way as for prints, the color material consumption amount for each area acquired after the separating of the area.
The image processor 23 having read out the specific condition determining program 2511 compares the color material consumption amount estimated in step S320 with the color material consumption amount's threshold as the specific condition read out from the specific condition storing area 255, thereby to determine whether or not the specific area matching the specific condition is present in the first image (step S330).
When it is determined that the specific area matching the specific condition is present, the image processor 23 reads out the specific area extracting program 2513. The image processor 23 having read out the specific area extracting program 2513 extracts a corresponding specific area from the first image (step S330; Yes→step S340).
Extracting the specific area from the first image, the image processor 23 reads out the access information acquiring program 2515. The image processor 23 having read out the access information acquiring program 2515 sends, to the external storage device 30, the specific area extracted in step S340 (step S350).
Then, the image processor 23 sends the identification code acquiring request to the external storage device 30 (step S360).
Acquiring the identification code from the external storage device 30, the image processor 23 reads out the image generating program 2517 (step S370).
In the first image, the image processor 23 having read out the image generating program 2517 replaces the image area, which corresponds to the specific area, with the identification code acquired from the external storage device 30, thereby to generate the second image (step S380).
The image processor 23, via the image outputter 21, outputs the second image as the document printout or document data (step S390), and ends the process.
By the way, when determining that the image replacing is not permitted (step S310; No) or the specific area matching the specific condition is not present (step S330; No), the image processor 23 outputs the first image as the document printout or document data via the image outputter 21 (step S400), and ends the process.
1.2.3 Regarding Process of External Storage Device 30
Then, the process of the external storage device 30 will be described using the flowchart in
When determining that the specific area has been received from the multifunction peripheral 10, the controller 31 of the external storage device 30 stores the received specific area in the specific area storing area 395 (step S410; Yes→step S420).
Then, the controller 31 determines whether or not the identification code acquiring request has been received from the multifunction peripheral 10 (step S430).
When determining that the identification code acquiring request has been received from the multifunction peripheral 10, the controller 31 reads out the identification code generating program 393.
The controller 31 having read out the identification code generating program 393 images the access information for accessing the specific area stored in the specific area storing area 395, thereby to generate the identification code (step S440).
Then, the controller 31 sends the generated identification code to the multifunction peripheral 10 (step S450).
Here,

1.2.4 Regarding Process of Terminal Device 50
Then, the process of the terminal device 50 will be described using the flowchart in
When the second image is output as the document printout, the controller 51 having read out the specific area acquiring program 613 controls the identification code input 59 thereby to acquire an identification code. In addition, when the second image is output as the document data, the controller 51 can acquire the identification code via the communicator 57 or the like (step S500).
When determining that the identification code has been acquired from the multifunction peripheral 10, the controller 51, based on the access information included in the identification code, sends the specific area acquiring request to the external storage device 30 (step S510).
Then, the controller 51 determines whether or not the specific area has been received (step S520). When determining that the specific area has been acquired, the controller 51 displays the received specific area on the display 53 (step S530), and end the process.
Then, an operation example according to the first embodiment will be described.
In addition to texts such as “RELEASING A DIGITAL FULL-COLOR MULTIFUNCTION PERIPHERAL <∘∘-ΔΔ>”, “∘∘ CORPORATION WILL RELEASE A DIGITAL FULL-COLOR MULTIFUNCTION PERIPHERAL <∘∘-ΔΔ>EQUIPPED WITH THE INDUSTRY'S FIRST □□□ FUNCTION.”, and the like, the Image-001A is formed with Obj-001 that illustrates an image of the digital color multifunction peripheral, and Obj-002 that has a table which summarizes product name, model name, sales period and monthly production volume, and a comparison graph. The present operation example will be described based on an assumption that the Obj-001 and the Obj-002 are the specific areas matching the specific condition, that is, the Obj-001 and the Obj-002 are objects causing a large color material consumption amount in the case of printing out.
From the Image-001A, the image processor 23 having read out the image replacing program 251 extracts the Obj-001 and Obj-002 as the specific areas matching the specific condition. The image processor 23 sends the extracted Obj-001 and Obj-002 to the external storage device 30, and makes the identification code acquiring request. In the Image-001A, the image processor 23 having acquired the identification code from the external storage device 30 replaces the image area, which corresponds to the Obj-001 and the Obj-002, with the identification code acquired from the external storage device 30, thereby to generate the second image.
The identification code to be replaced is converted to a size smaller than the image size of the original object, and the layout of the overall drawing area is adjusted; therefore, while the Image-001B retains the necessary information to be displayed to the user, the overall drawing size can be reduced compared to the Image-001A.
The object to be replaced with the identification code relates to the image area where the color material amount consumed in the case of printing out is larger than the predetermined threshold. Therefore, the color material consumption amount related to the formation of the Image-001B can be reduced.
The Code-001 and the Code-002 respectively include access information for accessing the corresponding original objects Obj-001 and Obj-002. The user of the terminal device 50 reads the Code-001 and Code-002 with the terminal device 50 and accesses the external storage device 30, thereby making it possible to acquire the Objects Obj-001 and Obj-002 stored in the specific area storing area 395.
In addition,
As described above, according to the first embodiment, the color material consumption amount related to the image formation in the specific area can be reduced, and adjusting the layout after the identification code replacing can also reduce the number of sheets of printing media, thus making it possible to reduce costs.
In addition, since the image of the specific area is sent to and stored in the external storage device 30, a decoder for decoding the coded secret information for each viewer environment is not required for visualization of the coded secret information. In addition, the image related to the specific area is managed in the external storage device 30. Therefore, even if some change should occur in the specific area, the specific area stored in the external storage device 30 can be manipulated. This allows for more flexible management. In addition, since the identification code including the access information for accessing the specific area can be generated by the external storage device 30, there is no risk of diffusing of the information necessary for decoding, making it possible to prevent any unspecified other person from viewing the information.
When the document data is to be rasterized for printing, counting the pixel value seen after the color conversion process of the chart/image area can estimate the color material consumption amount; for the sake of process simplicity, however, it is acceptable to determine, as a specific area, an object with an area equal to or more than a predetermined standard, based on merely the arrangement information (height and width sizes) of the chart/image area.
In addition, of the chart/image, the image area related to a color object may be a target to be replaced with the identification code, or only the color object may be sent to the external storage device 30 while all including the color object are printed in black and white. In this case, the identification code may be given to each color object, or the identification code may be given to each page that includes the color object.
In addition, it is allowed that, for example, as an input image of image search, using a monochrome printed object area without an identification code given acquires the corresponding color object from the external storage device 30 and displays the color object.
In a second embodiment, a case where, at the time of selecting the character size changing mode and as a result of character enlarging, an image area that reduces the number of characters outputtable within a predetermined page is present is defined as the specific condition. When the specific area matching the specific condition is present, sending the specific area to the external storage device 30 can suppress the number of sheets of print media consumed during the printing while improving the readability of the enlarged character.
2.1 Functional Configuration
The functional configuration of the second embodiment can be similar to that of the first embodiment, except that the configuration of a part of the image replacing program stored in the storage of the multifunction peripheral is different. Therefore, in the following description, different functional configuration will be described, and the same functional configuration will be omitted.
2.1.1 Regarding Multifunction Peripheral 70
In the second embodiment, the storage 75 stores an image replacing program 751 and the authenticating program 253, and secures the specific condition storing area 255 and the specific area storing area 257.
The image replacing program 751 is read out by the image processor 23 when executing the image replacing process on the input document printout or document data. The image replacing program 751 includes a specific condition determining program 7511, the specific area extracting program 2513, the access information acquiring program 2515, and the image generating program 2517.
The specific condition determining program 7511 is read by the image processor 23 when determining whether or not a specific area matching the specific condition is present in the first image that is included in the document printout or document data. In the second embodiment, an image area where, at the time of printing, copying, scanning, file exporting, data exporting, or the like, the character size changing mode to enlarge a character is selected, and as a result of the character enlarging, the number of outputtable characters is reduced is defined as the specific area. The specific condition including a threshold of the number of outputtable characters is stored in the specific condition storing area 255.
In the present disclosure, the file exporting is intended to output the image information by exporting the image information to a file to be distributed in a conference system or a file to be attached to an e-mail, for example, whereas the data exporting is, without being limited to the file exporting, intended to output the image information on a real time display such as display screen, for example.
A character information calculating program 7511a is read out by the image processor 23 when calculating the number of to-be-enlarged characters and an exclusive area of the character area, which includes the enlarged characters, relative to an outputtable area. The image processor 23 having read out the specific condition determining program 7511 compares the calculated number of enlarged characters with the threshold (as the specific condition read out from the specific condition storing area 255) of the number of characters outputtable within the page, and compares the calculated exclusive area with the threshold (as the specific condition read out from the specific condition storing area 255) of the outputtable area, thereby to determine whether or not a specific area matching the specific condition is present in the first image. In other words, with the first image involving the image area, and when, with the character enlarged, there is an image area that cannot be fit in the outputtable area, the image processor 23 determines this to be the specific area.
Functional configurations of the external storage device 30 and the terminal device 50 can be the same as those in the first embodiment, so the description thereof here is omitted.
2.2 Flow of Processes
The flow of processes of the second embodiment can be executed in a similar manner to the first embodiment. In the second embodiment, “calculate color material amount” process according to step S320 in
When determining in step S310 of
The number of to-be-enlarged characters, and the exclusive area can be calculated depending on (1) in the case of printing (2) or in the case of copying/scanning.
For example, (1) in the case of printing, the page description language output from the printer driver includes information such as the starting point of placement, size . . . etc., in addition to attribute information (text/vector/raster) of each area. Using the above pieces of information can specify the area where characters, when enlarged, contact or overlap each other. When a character string folding setting is made for the image area (vector/raster) portion, the area that can be possessed by the character area can be determined according to the setting type. This makes it possible to determine whether or not an image area that cannot fit in the outputtable area when the character is enlarged is present.
(2) When the paper document is read by the image input 19 (scanner), as in the case of copying/scanning, the character can be treated in the same way as in the case of (1) printing. Simply, magnifying the character as it is optically read can specify the area where the characters contact or overlap each other. In addition, reading the character portion (area) with the OCR (Optical character recognition) function can take the same action as the character string folding setting in (1).
Then, an operation example according to the second embodiment will be described.
In addition to texts such as “RELEASING A DIGITAL FULL-COLOR MULTIFUNCTION PERIPHERAL <∘∘-ΔΔ>” Tx-001A and “∘∘ CORPORATION WILL RELEASE A DIGITAL FULL-COLOR MULTIFUNCTION PERIPHERAL <∘∘-ΔΔ>EQUIPPED WITH THE INDUSTRY'S FIRST □□□ FUNCTION.” Tx-002A, the Image-002A is formed with Obj-003 that illustrates an image of the digital color multifunction peripheral. The present operation example describes an operation example in the case of enlarging the texts that relate to the Tx-001A and the Tx-002A.
When the characters included in the texts (within a single-dot dashed box) related to the Tx-001A and the Tx-002A are enlarged as exemplified by Image-002B in
Then, as a result of enlarging the texts related to the Tx-001A and the Tx-002A, as shown in
The image processor 23 sends the extracted Obj-001 to the external storage device 30, and makes the identification code acquiring request. In Image-002C shown in
As described above, according to the second embodiment, since the image of the specific area is sent to and stored in the external storage device 30, a decoder for decoding the coded secret information for each viewer environment is not required for visualization of the coded secret information. In addition, the image related to the specific area is managed in the external storage device 30. Therefore, even if some change should occur in the specific area, the specific area stored in the external storage device 30 can be manipulated. This allows for more flexible management. In addition, since the identification code including the access information for accessing the specific area can be generated by the external storage device 30, there is no risk of diffusing of the information necessary for decoding, making it possible to prevent any unspecified other person from viewing the information.
In addition, according to the second embodiment, the number of sheets of print media consumed during the printing can be suppressed while improving the readability of the enlarged character.
In a third embodiment, a case where an image area having an information amount larger than the information amount required on the drawing medium such as display screen or on the printing medium such as paper sheet is present is defined as the specific condition, and sending, to the external storage device 30, the specific area matching the specific condition can reduce the unnecessary redundant data amount.
3.1 Functional Configuration
The functional configuration of the third embodiment can be similar to that of the first embodiment, except that the configuration of a part of the image replacing program stored in the storage of the multifunction peripheral is different. Therefore, in the following description, different functional configuration will be described, and the same functional configuration will be omitted.
3.1.1 Regarding Multifunction Peripheral 90
In the third embodiment, the storage 95 stores an image replacing program 951 and the authenticating program 253, and secures the specific condition storing area 255 and the specific area storing area 257.
The image replacing program 951 is read out by the image processor 23 when executing the image replacing process on the input document printout or document data. The image replacing program 951 includes a specific condition determining program 9511, the specific area extracting program 2513, the access information acquiring program 2515, and the image generating program 2517.
The specific condition determining program 9511 is read out by the image processor 23 when determining whether or not the specific area matching the specific condition is present in the first image that is included in the document printout or document data. In the third embodiment, the image area having the information amount larger than the information amount required at the drawing medium or printing medium for printing, copying, scanning, file exporting, data exporting, or the like is defined as the specific area. The specific condition, including a threshold of the information amount required at the drawing medium or printing medium, is stored in the specific condition storing area 255.
An information amount calculating program 9511a is read out by the image processor 23 when calculating the specific area's information amount required at the drawing medium or printing medium. The image processor 23 having read out the specific condition determining program 9511 compares the calculated specific area's information amount with the information amount threshold, etc. as the specific condition read out from the specific condition storing area 255, thereby to determine whether or not the specific area matching the specific condition is present in the first image.

3.3 Operation Example
Then, an operation example according to the third embodiment will be described.
The present operation example describes the operation example in which the information amount of Obj-004 is larger than the specific area's information amount required at the drawing medium or printing medium. As shown in
Since the image area of the Obj-004 indicated by the single-dot dashed box in the figure is larger than the image area RE10 indicated by the dotted line in the figure, the image processor 23 having read out the image replacing program 951 extracts the Obj-004 as the specific area matching the specific condition.
The image processor 23 sends the extracted Obj-004 to the external storage device 30, and makes the identification code acquiring request. In Image-003B shown in
As described above, according to the third embodiment, since the image of the specific area is sent to and stored in the external storage device 30, a decoder for decoding the coded secret information for each viewer environment is not required for visualization of the coded secret information. In addition, the image related to the specific area is managed in the external storage device 30. Therefore, even if some change should occur in the specific area, the specific area stored in the external storage device 30 can be manipulated. This allows for more flexible management. In addition, since the identification code including the access information for accessing the specific area can be generated by the external storage device 30, there is no risk of diffusing of the information necessary for decoding, making it possible to prevent any unspecified other person from viewing the information.
In addition, according to the third embodiment, since the image related to the specific area stored in the external storage device 30 should be used only for the enlarged display or high-resolution printing, any redundant data amount unnecessary during the drawing such as presentation or during a normal printing, for example can be reduced. This can smoothen operations such as registering materials to a conference system and attaching to the e-mail.
In a fourth embodiment, a case where personal information such as face photograph, name, address, or the like is present in the first image that is included in the document printout or document data is defined as the specific condition, and sending the specific area to the external storage device 30 when the specific area matching the specific condition is present can prevent the personal information from being leaked to any unspecified other person.
4.1 Functional Configuration
The functional configuration of the fourth embodiment can be similar to that of the first embodiment, except that the configuration of a part of the image replacing program stored in the storage of the multifunction peripheral is different. Therefore, in the following description, different functional configuration will be described, and the same functional configuration will be omitted.
4.1.1 Regarding Multifunction Peripheral 110
In the fourth embodiment, the storage 115 stores an image replacing program 1151 and the authenticating program 253, and secures the specific condition storing area 255 and the specific area storing area 257.
The image replacing program 1151 is read out by the image processor 23 when executing the image replacing process on the input document printout or document data. The image replacing program 1151 includes a specific condition determining program 11511, a specific area extracting program 2513, the access information acquiring program 2515, and the image generating program 2517.
The specific condition determining program 11511 is read out by the image processor 23 when determining whether or not the specific area matching the specific condition is present in the first image that is included in the document printout or document data. In the fourth embodiment, at the time of printing, copying, scanning, file exporting, data exporting, or the like, a face photograph, and specific keywords such as name, phone number, and address are specified as a personal information-related item, and a character string in the table where the personal information-related item becomes the heading (title) or item name shall be treated as personal information. Then, the image area including the personal information shall be defined as the specific area, and the specific keywords and the like corresponding to the personal information shall be stored in the specific condition storing area 255.
A personal information determining program 11511a is read out by the image processor 23 when determining whether or not the information included in the image area is personal information. The image processor 23 having read out the specific condition determining program 11511 determines whether or not the information included in the image area is the personal information, thereby to determine whether or not the specific area matching the specific condition is present in the first image.
Functional configurations of the external storage device 30 and the terminal device 50 can be the same as those in the first embodiment, so the description thereof here is omitted.
4.2 Flow of Processes
The flow of processes of the fourth embodiment can be executed in a similar manner to the first embodiment. In the fourth embodiment, “calculate color material amount” process according to step S320 in

Then, an operation example of the fourth embodiment will be described.
In the present operation example, Obj-005A is an example of an object related to a face photograph of a specific individual. In addition, Obj-006A is an example of an object related to the personal information that describes the name and address of the participant who participated in the □□□ excursion. The image processor 23 having read out the image replacing program 1151 determines that these objects match the personal information as a specific condition, and extracts the Obj-005A and Obj-006A as specific areas matching the specific condition.
The image processor 23 sends the extracted Obj-005A and Obj-006A to the external storage device 30, and makes the identification code acquiring request. In Image-004B shown in
In addition, the object related to the face photograph is replaced with the identification code Code-005, and Obj-005B that has been made by subjecting the above object to a mosaicing, blurring, filling-in, or the like can be further placed.
The Obj-006A is an example of an object that specifies, as the personal information-related item, keywords such as name, telephone number, and address, and treats, as the personal information, the character string in the table where the personal information-related item becomes the heading (title) or item name. In this case, for example, as exemplified in Obj-006B, the character of the relevant item may be replaced with a predetermined hidden character, or the overall character string of the relevant item may be hidden at once. Not causing each item to have the information about access to the external storage device 30, but causing each page to have the information about access to the external storage device 30 is allowed.
In this way, a first condition is defined as the case where the image area includes the personal information other than the face photograph, and a second condition is defined as the case where the image area includes the face photograph; then in the first condition, the personal information is replaced with the image including the identification code, whereas in the second condition, it is possible to replace the face photograph with an image that was subjected to an image processes including at least mosaicing process, blurring process, filling-in process, or the like. In this case, further, the image can be replaced with both an image that has been subjected to the predetermined image process on the face photograph and an image that includes the identification code, as exemplified in
As described above, according to the fourth embodiment, since the image of the specific area is sent to and stored in the external storage device 30, a decoder for decoding the coded secret information for each viewer environment is not required for visualization of the coded secret information. In addition, the image related to the specific area is managed in the external storage device 30. Therefore, even if some change should occur in the specific area, the specific area stored in the external storage device 30 can be manipulated. This allows for more flexible management. In addition, since the identification code including the access information for accessing the specific area can be generated by the external storage device 30, there is no risk of diffusing of the information necessary for decoding, making it possible to prevent any unspecified other person from viewing the information.

For example, keywords such as “SECRET” and “CONFIDENTIAL related to the viewing restriction, and information related to the viewing restriction such as additional information such as attribute tag are stored in the specific condition storing area 255.
A viewing information determining program 13511a is read out by the image processor 23 when determining whether or not the viewing restriction given to the image area included in the first image corresponds to the specific condition. The image processor 23 having read out the specific condition determining program 13511 determines whether or not the viewing restriction included in the first image corresponds to the specific condition, thereby to determine whether or not the specific area matching the specific condition is present in the first image. Since the viewing restriction can be given to each image area included in the first image, the image processor 23 having read out the specific condition determining program 13511 determines whether or not the viewing restriction corresponds to the specific condition for all image areas.
Functional configurations of the external storage device 30 and the terminal device 50 can be the same as those in the first embodiment, so the description thereof here is omitted.

The image processor 23 sends the extracted Obj-007 to the external storage device 30, and makes the identification code acquiring request. In Image-005B shown in
As described above, according to the fifth embodiment, since the image of the specific area is sent to and stored in the external storage device 30, a decoder for decoding the coded secret information for each viewer environment is not required for visualization of the coded secret information. In addition, the image related to the specific area is managed in the external storage device 30. Therefore, even if some change should occur in the specific area, the specific area stored in the external storage device 30 can be manipulated. This allows for more flexible management. In addition, since the identification code including the access information for accessing the specific area can be generated by the external storage device 30, there is no risk of diffusing of the information necessary for decoding, making it possible to prevent any unspecified other person from viewing the specific area's image for which viewing is not permitted.
