BFS-Auto: High Speed ​​Book Scanner at over 250 pages / min - YouTube


This is the whole picture of the system


Scanning will be done even if you do not turn pages by hand after setting books


The part setting the right lower book is a page turning machine, realizing turning at high speed of over 250 pages per minute.


This is taken at the top left three cameras at high speed & high image quality


What is visible at the bottom left is the state of post-scan processing, there is no moment when flattening when you continue turning the page, but even if you scan the image in a bent state it corrects flatly.


We do not know at what moment the page turning is at a level of speed


Shooting will never be interrupted


Tracking the page surface at 500 fps in real time


Also, shooting was taken only at the moment the page was opened optimally, and there is no such thing as "Shot taken because it was no good".


Processing will also proceed at high speed


This is the one that was actually filmed, the left side page opened, it is curved toward the inside of the book (the right side of the page)


When processed, it becomes flat as if it was pressed against the board.


Moreover, the characters are clearly clear.



This is a scanner using Book Flipping Scanning technology studied by Ishikawa Oku laboratory of the University of Tokyo.The 14th Library Comprehensive ExhibitionSo the factory exhibition was done at the Dainippon Printing booth.

According to Dai Nippon Printing, "We introduced the developed book scanner to our factory and we are planning to start practical use for book digitization services such as library collections during fiscal 2013. We will also consider the external sales of book scanners in the future.That thing. How much will it cost to be sold ... ....
