a page number specifying unit that specifies the page number corresponding to each of the read images in the read image sequence using a reading result of the two-dimensional code image in the read image;

a page number determining unit that determines the page number corresponding to a target image which is a read image of which the page number is not specified by the page number specifying unit, using a position of the target image in the read image sequence, a position in the read image sequence, of the read image of which the page number is specified by the page number specifying unit, and the page number corresponding to the read image of which the page number is specified by the page number specifying unit;

a decoding text information specifying unit that specifies decoding text information corresponding to the target image using the text information that is stored in the history record storage unit and the page number corresponding to the target image that is determined by the page number determining unit; and

a print unit that prints a two-dimensional code in which the specified decoding text information is embedded.

2. The image processing device according to claim 1 , wherein

the page number determining unit determines a page number corresponding to a type of a relation that is commonly satisfied by the respective read images, of which the page number is specified by the page number specifying unit, as the page number corresponding to the target image.

3. The image processing device according to claim 2 , wherein

the two-dimensional code is a two-dimensional code that enables not only the page number of a document but also the document to be specified,

the page number specifying unit specifies the page number corresponding to each of the read images in the read image sequence and the document corresponding to each of the read image using a reading result of the two-dimensional code image in the read image, and

the page number determining unit determines the page number corresponding to the target image when the documents corresponding to the respective read images of which the page number is specified by the page number specifying unit are the same.

4. The image processing device according to claim 1 , wherein

the two-dimensional code is a two-dimensional code that enables not only the page number of a document but also the document to be specified,

the page number specifying unit specifies the page number corresponding to each of the read images in the read image sequence and the document corresponding to each of the read images using a reading result of the two-dimensional code image in the read image, and

the page number determining unit determines the page number corresponding to the target image when the documents corresponding to the respective read images of which the page number is specified by the page number specifying unit are the same.

5. A non-transitory computer readable medium storing a program for causing a computer to function as:

a history record storage unit that stores a history record comprising text information and a page number that are embedded in a two-dimensional code printed on each sheet of a combined image;

an image sequence acquisition unit that acquires a read image sequence comprising read images that are sequentially read by an image reading unit from each of a plurality of sheets on which the two-dimensional code is printed;

a page number specifying unit that specifies the page number corresponding to each of the read images in the read image sequence using a reading result of the two-dimensional code image in the read image;

a page number determining unit that determines the page number corresponding to a target image which is a read image of which the page number is not specified by the page number specifying unit using a position of the target image in the read image sequence, a position in the read image sequence, of the read image of which the page number is specified by the page number specifying unit, and the page number corresponding to the read image of which the page number is specified by the page number specifying unit;

a decoding text information specifying unit that specifies decoding text information corresponding to the target image using the text information that is stored in the history record storage unit and the page number corresponding to the target image that is determined by the page number determining unit; and

a print unit that prints a two-dimensional code in which the specified decoding text information is embedded.

6. An image processing method comprising:

storing a history record comprising text information and a page number that are embedded in a two-dimensional code printed on each sheet of a combined image;

acquiring a read image sequence comprising read images that are sequentially read by an image reading unit from each of a plurality of sheets on which the two-dimensional code is printed;

specifying the page number corresponding to each of the read images in the read image sequence using a reading result of the two-dimensional code image in the read image;

determining the page number corresponding to a target image which is a read image of which the page number is not specified using a position of the target image in the read image sequence, a position in the read image sequence, of the read image of which the page number is specified, and the page number corresponding to the read image of which the page number is specified;

specifying decoding text information corresponding to the target image using the stored text information and the page number corresponding to the target image that is determined; and

printing a two-dimensional code in which the specified decoding text information is embedded.
