Image processing apparatus, image processing system, non-transitory computer readable medium storing image processing program, and image processing method

1 . An image processing apparatus comprising:

a processor configured to:

acquire a document image sequence including a plurality of document images obtained by scanning a plurality of documents;

detect, using an algorithm, a repetition pattern in which a specific document size pattern is repeated in the document image sequence and determine a repetition cycle based on the detected repetition pattern; and

arrange and output a document image on each page such that the document image is a boundary of pages matched to the repetition cycle.

2 . The image processing apparatus according to claim 1 , wherein the processor is configured to: with one cycle of the repetition cycle as one unit, arrange the document image included in the one unit of a next cycle on a new page even though there is a space for arranging the document image included in the one unit of the next cycle on a page on which the document image included in the one unit is arranged.

3 . The image processing apparatus according to claim 1 , wherein the processor is configured to: adjust a size of the document image sequence to fit on one page with the repetition cycle as one unit and arrange the document image.

4 . The image processing apparatus according to claim 3 , wherein the processor is configured to: after receiving whether or not to adjust the size of the document image sequence:

in a case of adjusting the size of the document image sequence, adjust the size of the document image sequence to fit on one page with the repetition cycle as one unit and arrange the document image; and

in a case of not adjusting the size of the document image sequence, with one cycle of the repetition cycle as one unit, arrange the document image included in the one unit of a next cycle on a new page even though there is a space for arranging the document image included in the one unit of the next cycle on a page on which the document image included in the one unit is arranged.

5 . The image processing apparatus according to claim 1 , wherein the processor is configured to: generate a detection target image sequence by regarding, as one set, the document images in which a size of each of the document images in the document image sequence is regarded as having the same size, and detect a repetition cycle of a document size of the detection target image sequence.

6 . The image processing apparatus according to claim 5 , wherein the processor is configured to: calculate a size of the document image in the detection target image sequence, and obtain one repetition cycle and the number of repetitions of the detection target image sequence based on the calculated size.

7 . The image processing apparatus according to claim 6 , wherein the processor is configured to: in a case where there is the repetition cycle of the detection target image sequence, calculate the number of sheets per cycle of the document image sequence based on a boundary between repetitions, and arrange the document image so that a boundary of the cycle becomes the boundary of the pages.

8 . An image processing system comprising:

an image scanning apparatus that scans a plurality of documents and generates a document image sequence including a plurality of document images; and

the image processing apparatus according to claim 1 .

9 . A non-transitory computer readable medium storing an image processing program causing a computer to execute a process comprising:

acquiring a document image sequence including a plurality of document images obtained by scanning a plurality of documents;

detecting, using an algorithm, a repetition pattern in which a specific document size pattern is repeated in the document image sequence and determining a repetition cycle based on the detected repetition pattern; and

arranging and outputting a document image on each page such that the document image is a boundary of pages matched to the repetition cycle.

10 . An image processing method comprising:

acquiring a document image sequence including a plurality of document images obtained by scanning a plurality of documents;

detecting, using an algorithm, a repetition pattern in which a specific document size pattern is repeated in the document image sequence and determining a repetition cycle based on the detected repetition pattern; and

arranging and outputting a document image on each page such that the document image is a boundary of pages matched to the repetition cycle.
