The software used to scan books, called Optical Character Recognition software or OCR for short, required each page of the book to be flat. Google created some seriously nifty infrared camera technology that detects the three-dimensional shape and angle of book pages when the book is placed in the scanner. This information is transmitted to the OCR software, which adjusts for the distortions and allows the OCR software to read text more accurately. clipped from patft.uspto.gov United States Patent 7,508,978 Lefevere , et al.
