Abstract

A browsing control system includes a booklet that is acquired by binding a number of sheets, a specification unit that specifies a page number of a page opened in the booklet, and a controller that controls page turning of an electronic document depending on a difference between a page number specified by the specification unit before the page of the booklet is turned and a page number specified by the specification unit after the page thereof is turned.

First claim

What is claimed is:

1. A browsing control system comprising:
a booklet that is acquired by binding a number of sheets;
a specification unit that specifies a page number of a page opened in the booklet; and
a controller that controls page turning of an electronic document depending on a difference between a page number specified by the specification unit before the page of the booklet is turned and a page number specified by the specification unit after the page thereof is turned,
wherein the controller calculates the number of pages to be turned through the page turning of the electronic document by using a propagation function that defines the relationship between the difference and the number of pages to be turned through the page turning of the electronic document, and turns pages of the electronic document as many as the number of pages calculated.

2. The browsing control system according to claim 1 ,
wherein the propagation function is a function that maps the total number of pages of the booklet to the number of pages which is equal to or greater than the total number of pages of the electronic document.

3. The browsing control system according to claim 2 ,
wherein the propagation function is a function of which a slope monotonically increases with respect to the difference.

4. The browsing control system according to claim 3 ,
wherein the propagation function is a value which satisfies that the number of pages to be turned is equal to the difference in a section in which the difference is equal to or less than a threshold.

5. The browsing control system according to claim 2 ,
wherein the propagation function is a value which satisfies that the number of pages to be turned is equal to the difference in a section in which the difference is equal to or less than a threshold.

6. The browsing control system according to claim 2 ,
wherein information indicating a page number corresponding to each sheet is retained in each sheet of the booklet, and
the specification unit specifies a page number of an opened page by reading the information of the page number retained in the sheet corresponding to the opened page.

7. The browsing control system according to claim 1 ,
wherein the propagation function is a function of which a slope monotonically increases with respect to the difference.

8. The browsing control system according to claim 7 ,
wherein the propagation function is a value which satisfies that the number of pages to be turned is equal to the difference in a section in which the difference is equal to or less than a threshold.

9. The browsing control system according to claim 1 ,
wherein the propagation function is a value which satisfies that the number of pages to be turned is equal to the difference in a section in which the difference is equal to or less than a threshold.

10. The browsing control system according to claim 7 ,
wherein information indicating a page number corresponding to each sheet is retained in each sheet of the booklet, and
the specification unit specifies a page number of an opened page by reading the information of the page number retained in the sheet corresponding to the opened page.

11. The browsing control system according to claim 1 ,
wherein the propagation function is a function which satisfies that the number of pages to be turned through the page turning of the electronic document is 1 in a case where a magnitude of the difference is 1 and satisfies that the number of pages to be turned through the page turning of the electronic document is greater than the difference in a case where the magnitude of the difference is greater than 1.

12. The browsing control system according to claim 1 ,
wherein the propagation function is a function which satisfies that the number of pages to be turned through the page turning of the electronic document becomes greater as a speed at which the page of the booklet is turned becomes higher.

13. The browsing control system according to claim 1 ,
wherein information indicating a page number corresponding to each sheet is retained in each sheet of the booklet, and
the specification unit specifies a page number of an opened page by reading the information of the page number retained in the sheet corresponding to the opened page.

14. The browsing control system according to claim 13 ,
wherein the information indicating the page number is printed on the page of the sheet of the booklet in a form of an image code,
a mark capable of being recognized with a processing load less than a processing load in a case where the image code is decoded is further represented on the page of the sheet, and
the specification unit detects the image code from a captured image, decodes the detected image code to specify the page number in a case where the mark is recognized from the captured image, and does not try to detect the image code from the image in a case where the mark is not able to be detected from the captured image.

15. The browsing control system according to claim 1 ,
wherein the controller changes a current mode of the browsing control system to a specific mode if a specific operation is received from a user, and does not turn the page of the electronic document depending on the difference even though the page of the booklet is turned until the specific mode is off.

16. The browsing control system according to claim 1 ,
wherein the controller uses, as a page turning method of the electronic document, a relative method of controlling the page turning of the electronic document depending on the difference and an absolute method of controlling the page turning of the electronic document such that the page having the page number of the electronic document corresponding to the page number specified by the specification unit is displayed, and switches the page turning method if a specific operation is received from a user.

17. The browsing control system according to claim 1 ,
wherein the controller has, as an aspect of the page turning, a function of moving a display range of the electronic document by a movement amount corresponding to the difference.

18. A browsing device comprising:
a specification unit that specifies a page number of a page opened in a booklet acquired by binding a plurality of sheets; and
a controller that controls page turning of an electronic document depending on a difference between a page number specified by the specification unit before the page of the booklet is turned and a page number specified by the specification unit after the page is turned,
wherein the controller calculates the number of pages to be turned through the page turning of the electronic document by using a propagation function that defines the relationship between the difference and the number of pages to be turned through the page turning of the electronic document, and turns pages of the electronic document as many as the number of pages calculated.

19. A browsing control system comprising:
a booklet that is acquired by binding a number of sheets;
a specification unit that specifies a page number of a page opened in the booklet; and
a controller that controls page turning of an electronic document depending on a difference between a page number specified by the specification unit before the page of the booklet is turned and a page number specified by the specification unit after the page thereof is turned,
wherein at a first mode, the controller controls the page turning of the electronic document depending on the difference, and a
