(Processing of the Image Forming Apparatus 1)
The image forming apparatus 1 is provided with a first copy mode and a second copy mode. In the first copy mode, the image forming apparatus 1 forms scanned scan image information on a sheet. In the second copy mode, the image forming apparatus 1 forms background image information obtained by excluding extraction image information in a color region from the scan image information on the sheet.
The image forming apparatus 1 sets the copy mode according to input of the user received by the input section 14. In the present embodiment, it is assumed that the image forming apparatus 1 sets the copy mode to the second copy mode (Act 11).
The image forming apparatus 1 acquires identification information of the user when the user holds an ID card over a card reader (the acquisition section 15) (Act 12). The image forming apparatus 1 sends the identification information of the user to the server 2 (Act 13) and then receives an authentication result (Act 14).
The image forming apparatus 1 reads the image of the sheet through the reading section 11 in a case in which the user is admitted (YES in Act 15) and then generates the scan image information (Act 16).
The image forming apparatus 1 extracts the extraction image information corresponding to a preset condition from the scan image information, and meanwhile generates the background image information obtained by excluding the extraction image information from the scan image information (Act 17). The extraction image information is not printed. The following condition is considered as an extraction condition of the extraction image information.

    
    
        color image information (different color image information) of a color (second color) other than black (first color) with respect to image information of black.
        text.
        image information in a setting region of the scan image information.
    
    


In a case in which the extraction condition is the text, the image forming apparatus 1 carries out an OCR (Optical Character Recognition) processing for the scan image information to extract the text. In a case in which the extraction condition is the image information in the setting region, a region in which important information is recorded can be set to the setting region on a sheet printed in a predetermined form. For example, on a sheet printed with a medical record, a region in which information (name, address and diagnosis result by a doctor) of a patient is recorded can be set to the setting region. For example, on a meeting document, a region in which information that does not hope to be seen by meeting partners outside the meeting place is recorded can be set to the setting region.
The image forming apparatus 1 forms the background image information, the identification information (the first identification information) of the sheet and orientation information illustrating orientation of the sheet on the sheet (Act 18). The identification information and the orientation information may be two-dimensional codes such as QR (Quick Response) codes or proper symbols. The identification information and the orientation information may be separately formed by proper symbols. The forming positions of the identification information and the orientation information may or may not be overlapped with the background image information. The image forming apparatus 1 may form the background image information, the identification information of the sheet and the orientation information with a single color (e.g. black). In the present embodiment, it is assumed that position coordinates of the two-dimensional codes (the identification information and the orientation information) are predetermined. The position coordinates of the two-dimensional codes are set in the server 2 and the portable terminal 4 in advance.
The image forming apparatus 1 sends information of the sheet and information relating to the extraction image information that is not printed to the server 2 (Act 19). The information of the sheet contains size of the sheet, orientation in which the image forming apparatus 1 reads the sheet and the identification information. The information relating to the extraction image information contains, for example, the color image information, text information and image information in the setting region of the scan image information as the extraction image information. The information relating to the extraction image information contains position coordinates of the extraction image information in the sheet, identification information in the sheet and the position coordinates of the orientation information.
(Processing of the Display Apparatus 3)
The portable terminal 4 acquires an authentication key (second identification information) registered in the smart glass 5 from the smart glass 5 and sends the authentication key to the server 2. The portable terminal 4 receives the approval from the server 2 (Act 31).
The user observes that the sheet on which the image forming apparatus 1 forms the background image information passes through the smart glass 5.
The smart glass 5 photographs the identification information and the orientation information (the two-dimensional codes) with the image capturing section 54. The portable terminal 4 acquires the identification information and the orientation information via the smart glass 5 (Act 32).
The portable terminal 4 acquires position information containing the height of the display apparatus 3 (Act 33).
The portable terminal 4 sends the identification information, the orientation information and the position information to the server 2 at any time (Act 34).
The portable terminal 4 receives the extraction image information from the server 2 (Act 35).
The portable terminal 4 controls the display apparatus 3 to project the extraction image information from the projection section 53 to the optical member 52 in order to enable the user to confirm the extraction image information in a state of overlapping with the background image information by sight (Act 36).
In this way, the user can view the extraction image information that is not printed on the sheet through the display apparatus 3, and image information identical to the scan image information.
The portable terminal 4 calculates orientation of the sheet and a distance to the sheet according to the identification information or the orientation information (the two-dimensional code). The portable terminal 4 calculates a display position of the extraction image information according to the position of the identification information or the orientation information (the two-dimensional code), the orientation of the sheet and the distance to the sheet. The portable terminal 4 calculates a display magnification of the extraction image information according to the distance to the sheet. The portable terminal 4 controls display operations of the extraction image information in the smart glass 5 on the basis of the calculated display position and display magnification of the extraction image information.
(Processing of the Server 2)
The server 2 receives the identification information of the user from the image forming apparatus 1 (Act 21). The server 2 carries out a user authentication and sends the authentication result to the image forming apparatus 1 (Act 22).
The server 2 receives the information of the sheet (the size of the sheet, the orientation in which the image forming apparatus 1 reads the sheet and the identification information) and the information (the extraction image information, the position coordinate of the extraction image information in the sheet, the identification information in the sheet and the position coordinate of the orientation information) relating to the extraction image information from the image forming apparatus 1 (Act 23). The server 2 associates the size of the sheet, the orientation in which the image forming apparatus 1 reads the sheet, the extraction image information, the position coordinate of the extraction image information in the sheet, the identification information in the sheet and the position coordinate of the orientation information with the identification information of the sheet in the storage section 231.
The server 2 receives the authentication key registered in the smart glass 5 from the portable terminal 4 to carry out a device authentication (Act 24).
The server 2 acquires the identification information of the sheet, the position information and the orientation information from the portable terminal 4 (Act 25).
If receiving the identification information of the sheet from the portable terminal 4, the server 2 sends the extraction image information associated with the identification information of the sheet to the portable terminal 4 (Act 26).
At this time, the server 2 restricts the extraction image information to be sent according to a setting condition. The setting condition is registered in the storage section 231.
For example, the following setting condition is considered.

    
    
        In a case in which the position of the smart glass 5 (the portable terminal 4) is outside the setting region, the server 2 does not send the extraction image information. It is exemplified as the setting region that the smart glass 5 or the portable terminal 4 is positioned inside the office of the company or within a radius value set from the image forming apparatus 1 that prints the background image information. The position of the image forming apparatus 1 is pre-registered in the storage section 231.
        The server 2 does not send the extraction image information according to levels of the authentication keys registered in the smart glass 5. The levels are divided for each authentication key in advance, and allowance/disallowance of the sending of the extraction image information is set for each level.
    
    


Further, the server 2 may send the processed extraction image information to the portable terminal 4. For example, in a case in which the extraction image information is the text, the server 2 may translate the text (a first text) according to a translation setting and send the translated text (a second text) to the portable terminal 4 as the extraction image information. Languages to be translated may be set in the translation setting. For example, in a case in which the text is Japanese, the translation setting is used to translate the text into English. The translation setting may be carried out on the basis of the position information (country and area) of the smart glass 5 (the portable terminal 4). For example, the translation setting may be used to translate the text into an official language of a country where the position information of the smart glass 5 is arranged.
The display system 100 extracts image information in a color region from the scanned image at the time of a copy processing, and enables the user to confirm the image information in the color region by sight with the smart glass 5 as the extraction image information. In this case, as the display system 100 prints the background image information obtained by excluding the image information in the color region, the background image information only in black is printed, thereby suppressing the cost of printing.
The display system 100 extracts image information in a region of the sheet on which important information is recorded, and enables the user to confirm the important image information by sight with the smart glass 5 as the extraction image information. In this case, the display system 100 prints the background image information obtained by excluding the important image information, and thus the risk of information leakage can be reduced.
The display system 100 can restrict the sending of the extraction image information according to the position information of the smart glass 5 (the portable terminal 4). For example, only when the user is inside the office of the own company, the display system 100 can send the extraction image information to the smart glass 5 (the portable terminal 4) of the user. Further, as the display system 100 also acquires the height of the display apparatus 3, even when the office is inside the building, accuracy of the restriction based on the position information can be excellent. Thus, through the display system 100, the risk of the information leakage can be reduced.
The display system 100 extracts the text, and can translate the extracted text on the basis of the position information of the smart glass 5. The display system 100 can enable the user to confirm the translated text by sight with the smart glass 5 as the extraction image information, which is convenient.
(Modification)
The image forming apparatus 1 may send not only the extraction image information, but also the scan image information and the background image information to the server 2.
The portable terminal 4 may carryout part of the processing of the server 2. For example, the portable terminal 4 may carry out the translation of the text.
The extraction condition of the extraction image information and a condition of restricting the sending of the extraction image information to the display apparatus 3 may be combinations of a plurality of conditions.
In the foregoing embodiment, the image forming apparatus 1 carries out the extraction processing at the time of the copy processing; however, the image forming apparatus 1 may send the scan image information to the server 2 after scanning in the copy processing. The server 2 may extract the extraction image information from the scan image information to generate the background image information. The server 2 sends the background image information to the image forming apparatus 1, and the image forming apparatus 1 may print the background image information.
Though the processing at the time of the copying is described in the foregoing embodiment, a processing at the time of the printing can also be carried out similarly to the copy processing. For example, the server 2 may receive a print job from a PC (Personal Computer) and generate the background image information while extracting the extraction image information from the image information in the print job. The server 2 may enable the image forming apparatus 1 to print the background image information and meanwhile send the extraction image information to the smart glass 5 (portable terminal 4).
The smart glass 5 (the display apparatus 3) may not be a monocular type that displays the extraction image information only to one eye of one side and may be a binocular type that displays the extraction image information to both eyes of both sides. The smart glass 5 may enable the user to confirm the extraction image information by sight with the use of a transmission-type display, or scan the retina of the user with a laser to enable the user to confirm the extraction image information by sight. The smart glass 5 may enable the user to confirm the extraction image information by sight with a proper method.
The reading section 11 may be equipped with a CCD for R, a CCD for G, a CCD for B and a CCD for K, or may be a constitute of reading an image in monochrome.
As stated above in detail, according to the technology recorded in the specification, a technology of cooperating with the smart glass in print can be provided.
