In this embodiment, an MFP that is the above-described multifunction digital image forming apparatus is used as the image processing apparatus. Hereinafter, the image processing apparatus is also referred to as an MFP.

  The CPU 11 operates based on various applications such as the OS 2 to control the entire MFP 1 and control basic functions such as a copy function, a printer function, a scan function, and a facsimile function. In this embodiment, a two-dimensional code is generated and displayed, and the processing will be described later.

  The ROM 12 is a memory that stores an operation program of the CPU 11 and the like.

  The RAM 13 is a memory that provides a work area when the CPU 11 operates based on an operation program.

  The display unit 14 includes a touch panel type liquid crystal or the like that displays a message, an operation screen, or the like.

  The storage unit 15 is configured by a non-volatile storage device such as a hard disk drive (HDD), for example, a two-dimensional code generated based on a two-dimensional code generation / display application, IP address information of its own device, and a network Information stored as a two-dimensional code such as information, performance information about a portable terminal device (not shown) as a reading device that reads the two-dimensional code, image data of a document read by the scanner unit 16, a program Memorize etc.

  The scanner unit 16 is a reading unit that reads an image of a document placed on a document table (not shown) and outputs image data.

  The printer unit 17 prints image data of a document read by the scanner unit 16, print data from a user terminal, and the like according to an instructed mode.

  The network controller 18 transmits and receives data by controlling communication with portable terminal devices and other external devices on the network.

  The OS 2 is basic software for managing the entire MFP. The native application P / F 3 includes middleware that operates the copy application 4, the scan application 5, the browser 6, and the like.

  The copy application 4 is an application for realizing a copy function, the scan application 5 is an application for realizing a scan function by the scanner unit 16, and the browser 6 is an application for browsing information on the web.

  The web server 7 is an internal server that transmits information on the web, and the two-dimensional code generation / display application 8 is an application that operates on the browser 6 to generate a two-dimensional code and displays it on the display unit 14. The application 9 is another application that operates on the browser 6. The two-dimensional code generation / display application 8 is upgraded to add functions.

  Next, two-dimensional code generation and display processing by the MFP shown in FIG. 1 will be described with reference to the flowchart of FIG. This processing is executed when the CPU 11 of the MFP operates according to programs such as the OS 2 and the two-dimensional code generation / display application 8 recorded in the ROM 12, the storage unit 15, and the like. In this embodiment, a case where the two-dimensional code is a QR code (registered trademark) will be described.

  The process shown in the flowchart of FIG. 2 is started, for example, when the logged-in user presses a two-dimensional code generation button (not shown) displayed on the display unit 14.

  In FIG. 2, storage information acquisition processing is performed in step S01. Specifically, as shown in the subroutine of FIG. 3, first, information recorded in the storage unit 15 of the own device is acquired (step S011). Examples of information stored include network information including the IP address of the device itself and wireless network information (SSID, password, etc.) of the device itself. However, the information is not limited to these, and a two-dimensional code is read. Any information may be used as long as it is necessary for registration setting of the MFP or communication setting with the MFP in the portable terminal device or the like. In addition, authentication information, a password, and the like of a user who has logged into the own apparatus may be included.

  After acquiring the stored information, the acquired information is converted into a storage information format (step S012 in FIG. 3). FIG. 6 shows a state converted into the storage information format. In this example, the IP address information and the network information are converted using a hierarchical / expandable JSON format.

  Returning to FIG. 2, after the storage information acquisition process, parameters for generating a two-dimensional code such as a model number and a structural unit of the two-dimensional code are determined in step S02.

  As is well known, parameters for generating a QR code (registered trademark) include a structural unit, a model number, an error correction level, a mode, and the like. The amount of stored information is determined by the setting value of each parameter.

  The structural unit is the smallest unit cell that constitutes the symbol of the code, as indicated by a broken-line circle in FIG. In addition, model numbers 1 to 40 exist, and as illustrated in FIG. 7B, the number of cells on one side is determined by each model number, and the number of stored characters is different. A lot of information).

  As illustrated in FIG. 7C, the error correction level is a level at which stored information can be read even if a part of the code is dirty, and can be restored up to 30%.

  The mode is a setting of a character type of information to be stored, and includes a number mode, an alphanumeric mode, a kanji mode, a mixed mode, and the like.

  In the determination of the parameters for generating the two-dimensional code in step S02, the model number, the structural unit, and the like are determined so that the information to be stored is larger than the size that can be stored and is smaller (first size). That is, as shown in FIG. 4, after confirming the information amount of the stored information in step S021, the parameters are determined in step S022 so that the first information size can be stored and the first size is small.

  Returning to FIG. 2, after determining the parameters, enlargement ratio determination processing is executed in step S03. This process is a process of determining an enlargement ratio for enlarging the first size two-dimensional code generated by the parameter determined in step S02 to the second size according to the appropriate size.

  Here, the appropriate size is a size suitable for a reading device such as a portable terminal device that reads a two-dimensional code to read the two-dimensional code.

  The appropriate size may be registered in advance in the storage unit 15 for each type of reading device, or based on the resolution of the display unit 14 (size of the display unit 14) and the reading performance of the two-dimensional code by the reading device. You may decide each time. The reading performance of the two-dimensional code by the reading device may be registered in advance in the storage unit 15 for each type of reading device, or may be acquired from the reading device by wireless connection to the reading device.

  The determination of the enlargement ratio in step S03 is specifically performed as shown in FIG. That is, after confirming the resolution (size) of the display unit (operation panel) 14 in step S031, in step S032, the reading performance of the target portable terminal device or the like is acquired to determine an appropriate size, and in step S033. Then, the enlargement ratio is determined so that the determined appropriate size is obtained.

  Note that if the first size of the two-dimensional code is not smaller than the appropriate size, the enlargement process is not necessary. Therefore, the enlargement factor determination process is performed when the first size of the two-dimensional code is smaller than the appropriate size. It is desirable to be executed only on.

  After determining the enlargement ratio, when the two-dimensional code having the first size generated with the determined parameters is enlarged to the second size with the determined enlargement ratio in step S04 of FIG. It is determined whether or not the size of the two-dimensional code is equal to or smaller than the display area of the display unit 14, in other words, whether or not the size of the two-dimensional code can be displayed in the display area.

  FIG. 8 shows a screen on which the two-dimensional code is displayed on the display unit 14. A two-dimensional code display area 141 is formed at the lower left half of the screen, and the two-dimensional code 100 is displayed in the two-dimensional code display area 141. In addition, a name display area 142 of a cooperation application for cooperation with the mobile terminal device is formed above the two-dimensional code display area 141, and the usage instruction display area 143 of the cooperation application is displayed in the right half of the screen. Is formed.

  In step S04, it is determined whether or not the second size two-dimensional code 100 after the enlargement process is equal to or smaller than the two-dimensional code display area 141. The device information stored in the two-dimensional code has a large difference in the amount of information depending on the setting contents of the target MFP, and may be larger than the display area particularly when the amount of information is large. Even when only the two-dimensional code is displayed on the display unit 14, the display unit 14 may be larger than the display screen size if the resolution of the display unit 14 is small.

  If the area is equal to or smaller than the two-dimensional code display area 141 (YES in step S04), after the two-dimensional code having the first size is generated in step S05, the two-dimensional code having the first size is determined in step S06. The enlargement process is performed at the enlargement ratio to obtain the second size which is an appropriate size. Since this enlargement processing is performed based on the two-dimensional code generation / display application 8 that operates on the browser, the generation / display processing of the two-dimensional code is performed in the display description language of the display unit 14 (for example, HTML of a web browser). This is done by rewriting the size setting part of the two-dimensional code display part. Thereby, it is possible to enlarge only the two-dimensional code without enlarging the display object other than the two-dimensional code. Next, the two-dimensional code of the second size is displayed on the display unit 14 in step S07.

  If the two-dimensional code 100 is not smaller than the two-dimensional code display area 141 in step S04, in other words, if the second size of the two-dimensional code 100 exceeds the size of the two-dimensional code display area 141 (NO in step S04). ) Since the two-dimensional code 100 is displayed outside the two-dimensional code display area 141 and may be displayed in a duplicated manner with the display objects in the other display areas 142 or 143, in step S08, in step S02 Check whether the determined parameter can be changed.

  If it can be changed (YES in step S08), in step S09, the parameter change such as lowering the error correction level or changing the mode so that the second size of the two-dimensional code after the enlargement process is reduced. After performing, return to step S04. When the second size of the two-dimensional code becomes equal to or smaller than the display area 141 due to the parameter change, each process of generation (step S05), enlargement (step S06), and display (step S07) of the two-dimensional code is performed. As a result, the enlarged two-dimensional code of the second size can be reliably displayed in the display area 141. If the parameter cannot be changed (NO in step S08), the process proceeds to step S10.

  In step S10, it is determined whether or not the layout of the display areas 142 and 143 other than the two-dimensional code display area 141 can be changed. If the layout can be changed (YES in step S10), in step S11, the arrangement of the display area 142 or 143 is changed so as to avoid overlapping display with the two-dimensional code, and then the process returns to step S04.

  If the layout of the other display areas 142 and 143 cannot be changed in step S10 (NO in step S10), the storage information is changed so that the size of the two-dimensional code is reduced in step S12. As an example of the change, information that can be manually input by a portable terminal device or the like can be removed from the stored information. In this case, the removed information is manually input by a mobile terminal device or the like. By changing the stored information, the size of the two-dimensional code can be reduced, and the two-dimensional code 100 can be reliably displayed in the display area 141.

  After the storage information is changed, the process returns to step S02, and the parameters for generating the two-dimensional code are determined again.

  As described above, in this embodiment, the two-dimensional code of the first size is enlarged to the second size to obtain an appropriate size that can be read by a two-dimensional code reader such as a portable terminal device. The size two-dimensional code is displayed on the display unit 14. That is, instead of directly generating a two-dimensional code having an appropriate size suitable for reading by the two-dimensional code reader, it is only necessary to generate a two-dimensional code having a first size smaller than the appropriate size. It's short. Therefore, the time until the two-dimensional code of the second size, which is an appropriate size, is displayed on the display unit 14, and the waiting time of the user until it is displayed can be reduced.

  Further, the generated two-dimensional code of the first size is displayed on the display unit 14 after being enlarged to the second size at an enlargement ratio determined from the first size and the appropriate size. In this state, the two-dimensional code having the second size is an appropriate size for the reading device, and therefore the reading device can accurately read the two-dimensional code.

  In the above embodiment, the MFP generates the first size two-dimensional code on its own device. However, by acquiring the first size two-dimensional code generated on the external device, the MFP can generate two-dimensional code. It is good also as a structure which produces | generates a code | cord | chord.

  The operation of the MFP in this case is shown in the flowchart of FIG. Note that steps S01-03 and S08-12 in the flowchart shown in FIG. 2 are the same in the flowchart in FIG.

  In step S04, it is determined whether or not the second size two-dimensional code 100 after the enlargement process is equal to or smaller than the two-dimensional code display area 141. If it is equal to or smaller than the two-dimensional code display area 141 (YES in step S04), in step S051, an external two-dimensional code generation device (not shown) is requested to generate a two-dimensional code using the parameters determined in step S02 of FIG. ).

  Next, in step S052, it waits for reception of the two-dimensional code generated by the two-dimensional code generation device (NO in step S052), and when received (YES in step S052), in step S06, the second size of the first size is received. The enlargement process is performed at the enlargement rate determined for the dimension code, and the second size, which is an appropriate size, is set. Next, the two-dimensional code of the second size is displayed on the display unit 14 in step S07.

  Thus, the external two-dimensional code generation device can reliably generate the two-dimensional code having the first size smaller than the appropriate size.

  Further, the CPU 11 determines whether or not the MFP has a function capable of executing the enlargement process. If it is determined that the function does not exist, the two-dimensional code is generated by increasing the constituent unit of the two-dimensional code. It is good also as a structure. In this case, a two-dimensional code having an appropriate size is directly generated regardless of the enlargement process.
