The gender area 91 is a rectangular area formed by using two points of coordinates (100, 150) and coordinates (750, 350) with the upper left corner of the image 90 as the origin.

  The address area 92 is an area for displaying information related to the address. The address area 92 is a rectangular area formed by using two points of coordinates (100, 450) and coordinates (1100, 700) with the upper left corner of the image 90 as the origin.

  The signature area 93 is an area for displaying information related to the signature. The signature area 93 is a rectangular area formed by using two points of coordinates (100, 900) and coordinates (1100, 1150) with the upper left corner of the image 90 as the origin.

The image 90 includes a first two-dimensional barcode 94 to 99 and a second two-dimensional barcode 100.
The first two-dimensional barcodes 94 to 99 include information related to the form. The first two-dimensional barcodes 94 to 99 are examples of the first image code 11.

  Specifically, the first two-dimensional barcodes 94 to 96 include information related to the layout. The first two-dimensional barcode 94 includes coordinate information (coordinates (100, 150) and coordinates (750, 350)) of two diagonal points of the sex region 91 as information that can identify the sex region 91.

The first two-dimensional barcode 95 includes coordinate information (coordinates (100, 450) and coordinates (1100, 700)) at two diagonal points of the address area 92 as information that can identify the address area 92.

The second two-dimensional barcode 100 is an example of the second image code 12. The display mode of the second two-dimensional barcode 100 is not limited to the preset display position of the form, but may be any display mode that can be distinguished from the first two-dimensional barcodes 94 to 99.

  The second two-dimensional barcode 100 includes a specific information table. Here, the specific information table will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of the specific information table in the second embodiment.

  The identification information table 100a is a table that can identify the first two-dimensional barcodes 94 to 99 included in the image 90. The server device 60 uses the specific information table 100a when selecting an information acquisition target from the first two-dimensional barcodes 94-99. The specific information table 100 a is an example of the selection information 13.

  The specific information table 100a includes a relative position and attribute information. The relative position is information that can identify the positional relationship of the first two-dimensional barcodes 94 to 99 in the image 90. The relative position is a relative positional relationship between the first two-dimensional barcodes 94 to 99 set with reference to the origin of the image 90. According to such a relative position, the positional relationship between the first two-dimensional barcodes 94 to 99 can be grasped more simply than the coordinates.

  For example, in the first two-dimensional barcode 94, the value of the X coordinate is the smallest among the first two-dimensional barcodes 94 to 99, and the value of the Y coordinate is also the smallest. Therefore, since the relative position from the left is “1” and the relative position from the top is “1”, (1, 1) is set in the item of relative position.

  The first two-dimensional barcode 95 has an X coordinate value that is the smallest among the first two-dimensional barcodes 94 to 99 and a Y coordinate value that is the second smallest. Therefore, since the relative position from the left is “1” and the relative position from the top is “2”, (1, 2) is set in the item of relative position. The first two-dimensional barcode 96 has an X coordinate value that is the smallest among the first two-dimensional barcodes 94 to 99 and a Y coordinate value that is the fifth smallest. Accordingly, since the relative position from the left is “1” and the relative position from the top is “5”, (1, 5) is set in the item of relative position.

  The first two-dimensional barcode 97 has the fourth smallest X-coordinate value among the first two-dimensional barcodes 94 to 99 and the third smallest Y-coordinate value. Accordingly, since the relative position from the left is “4” and the relative position from the top is “3”, (4, 3) is set in the item of relative position. The first two-dimensional barcode 98 has the second smallest X-coordinate value among the first two-dimensional barcodes 94 to 99 and the fourth smallest Y-coordinate value. Therefore, since the relative position from the left is “2” and the relative position from the top is “4”, (2, 4) is set in the item of relative position.

  The first two-dimensional barcode 99 has the third smallest X-coordinate value among the first two-dimensional barcodes 94 to 99 and the fourth smallest Y-coordinate value. Accordingly, since the relative position from the left is “3” and the relative position from the top is “4”, (3, 4) is set in the item of relative position.

  The attribute information is information that can identify the attributes of the first two-dimensional barcodes 94 to 99. The attribute is information that can identify the role. For example, the first two-dimensional barcodes 94 to 99 used in the same role have the same attribute information. Based on the attribute information, the first two-dimensional barcodes 94 to 99 are classified into several sections. For example, since the first two-dimensional barcode 94 includes information related to the layout of the sex region 91, the attribute information of the first two-dimensional barcode 94 is “sex”. Since the first two-dimensional barcode 95 includes information related to the layout of the address area 92, the attribute information of the first two-dimensional barcode 95 is “address”. Since the first two-dimensional barcode 96 includes information regarding the layout of the signature area, the attribute information of the first two-dimensional barcode 96 is “signature”. Since the first two-dimensional barcode 97 includes information regarding an address, the attribute information of the first two-dimensional barcode 97 is “address”. Since the first two-dimensional barcodes 98 and 99 include information for customers, the attribute information of the first two-dimensional barcodes 98 and 99 is “customer”.
