Recently filed patent 7508978 explains how Google's proprietary book scanning technology works. Google created infrared camera technology that detects 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.
