acquires, as the first information, a captured image in which the currently read part of the paper book is pointed, from the image capturing device,
recognizes a currently read page from the captured image, and
causes a section including the currently read part pointed in the recognized currently read page to be displayed in the e-book on the display.
3 . The information processing apparatus according to claim 1 ,
wherein the processor
causes, to be displayed as the book image on the display, an image in which among pages of the paper book, a layout of a page including the currently read part indicated by the second information is represented and an image in which the currently read part is represented in the layout.
4 . The information processing apparatus according to claim 3 ,
wherein the processor
causes, to be displayed as the book image on the display, an image of a side view of the paper book and an image in which a position of the page including the currently read part indicated by the second information is represented in the image of the side view.
5 . The information processing apparatus according to claim 3 ,
wherein the processor
causes the book image to be displayed when a period of time in which the e-book is not used is longer than or equal to a threshold.
6 . The information processing apparatus according to claim 4 ,
wherein the processor
causes the book image to be displayed when a period of time in which the e-book is not used is longer than or equal to a threshold.
7 . The information processing apparatus according to claim 1 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
8 . The information processing apparatus according to claim 2 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
9 . The information processing apparatus according to claim 3 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
10 . The information processing apparatus according to claim 4 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
11 . The information processing apparatus according to claim 5 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
12 . The information processing apparatus according to claim 6 ,
wherein the processor
acquires, from the image capturing device, a cover image captured as an image of a cover of the paper book,
identifies the work contained in the paper book on a basis of the acquired cover image, and
displays, on the display, the currently read part of the paper book indicated by the acquired first information as applied to the e-book containing the identified work.
13 . The information processing apparatus according to claim 1 ,
wherein the processor
causes an image representing a page of the paper book to be displayed as the book image, the page including the currently read part indicated by the second information.
14 . An information processing apparatus comprising:
displaying means for displaying an e-book containing a work identical to a work in a paper book;
image capturing means; and
processing means for
acquiring first information indicating a currently read part of the paper book from the image capturing device of the information processing apparatus,
acquiring second information indicating a currently read part of the e-book based on a user input to the display of the information processing apparatus,
displaying, on the displaying means, the currently read part of the paper book as applied to the e-book, the currently read part being indicated by the acquired first information, and
displaying, on the displaying means, a book image in which the currently read part of the e-book is represented in the paper book, the currently read part being indicated by the acquired second information.
15 . The information processing apparatus according to claim 1 , wherein the book image is displayed on the display to indicate the currently read part as applied to the paper book, without requiring a user to open or refer to the paper book.
