A research team led by Professor Masatoshi Ishikawa of the University of Tokyo has developed a prototype scanner that allows users to scan a book simply by rapidly flipping its pages. A high-speed camera operating at 500 fps and producing pictures with a resolution of 1280 x 1024 pixels, takes pictures of the page and its contents of text and images under ordinary light. A laser then projects lines on the page, and the camera captures this image as well. The lines allow the system to adjust for the curvature and distortion of pages as they are being flipped, and the software reconstructs the image into a digitized picture of a flat, regular page.
