Google’s Book Scanning Technology Revealed
Google was awarded a patent for a device to rapidly scan high-quality of images of books last March, as reported by NPR and CNet. However, no one has been able to get a glimpse of how the system works in practice, until now. Researchers Nakashima, Watanabe, Komuro, and Ishikawa of the University of Tokyo have published an article fully explaining and providing pictures of a system nearly identical to that in Google’s patent. It is not clear whether the Japanese researchers or Google came up with the idea first, but the University of Tokyo article does an excellent job of explaining the book scanning technology.
