High Speed Book Scanner
Simply turning pages of a book quickly may not seem like the best way to scan it. A Japanese research group at Tokyo University has created new software that allows hundreds of pages to be scanned within minutes. Scanning text is normally a boring process with each page having to be inserted into a scanner, but the team led by Professor Masatoshi Ishikawa uses a high speed camera that takes 500 pictures a second to scan pages as they are turned by workers.
Normal scanners can only scan the information that is actually before them on the page. This high speed book scanner uses a camera that captures pages at 1000fps as they are turned. A system built in allows it to automatically correct any changes to the text due to the page bending as well as light differences due to shadows. “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.
The current system is able to scan an average 250-page book in a little over 60 seconds using basic puter hardware. While it now requires extra time to process the scanned images (影像), the researchers hope to eventually make the technology both faster and much smaller. “In the more distant future, once it bees possible to put all of this processing on one chip (芯片) and then put that in an iPad or iPod, one could scan just using that chip. At that point, it bees possible to scan something quickly to save for later reading,” Ishikawa said.
Being able to scan books with an iPhone may be further off, but Ishikawa says that a mercial version of the large-scale puter based scanning system could be available in two or three years. While the technology has the potential to take paper books into the digital age, it remains to be how publishers will react to people scanning their books while just turning pages quickly.
