The system, developed by lab members Takashi Nakashima and Yoshihiro Watanabe, lets you scan a book by rapidly flipping its pages in front of a high-speed camera. They call this method book flipping scanning. They told me they can digitize a 200-page book in one minute, and hope to make that even faster.
The camera operates at 500 frames per second, with a resolution of 1280 by 1024 pixels. For each frame, the system alternates between two capture modes. First it shines regular light on the page and captures text and images. Then a laser device projects lines on the page and the camera captures that as well.
I can't imagine how long it would take my scanner to digitalize a book. Isn't technology amazing?
