Fastest scanner to flip through book

Scanning paper is normally a tedious process with each page having to be inserted into a flat-bed scanner, but the team led by professor Masatoshi Ishikawa use a high speed camera that takes 500 pictures a second to scan pages as they are flipped.

Normal scanners can only scan the information that is actually before them on the page. The new scanner which is being developed is able to deal with the fact that pages that are being flipped are normally deformed in some fashion.

“It takes a shot of the shape, then it calculates the shape and uses those calculations to film the scanning,” Ishikawa said, explaining the system used to reconstruct the original page.

“As it can film while understanding the underlying shape, it’s very easy to then take the pages that are being scanned and save them as a normal flat copy.” The current system is able to scan an average 200-250 page book in a little over 60 seconds using basic computer hardware that is available off-the-shelf.

“In the more the distant future, once it becomes possible to put all of this processing on one chip and then put that in a iPad or iPod, one could scan just using that chip. At that point, it becomes possible to scan something quickly to save for later reading,” Ishikawa said.
