In a story from Reuters, A Professor Ishikawa has created a scanner that can process hundreds of pages a minute. Using off-the shelf equipment, it takes 500 photos a second and calculates the curves of the pages, with the net effect that a book can be scanned as someone flips through it. Video here. As the story says,
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 flipping through them.
On that note, it is worth mentioning that India has just passed copyright legislation that seems quite balanced.
