Google has found that traditional scanning of books using software is very slow. So they have patented technology which they hope will increase the speed in which books are scanned for online viewing. The process involves infrared technology to scan the pages at a quicker pace. According to an article NewScientist Tech which states the following information:

However, last week Google was granted a patent (US 7508978) on an answer to this problem. Its trick is to project an infrared pattern onto the open page spread. This lets a pair of infrared cameras map the three-dimensional shape of the pages by detecting distortion to the pattern. This in turn allows the distortion of the text to be determined – and therefore the degree of correction needed to read it accurately.

For any of us who have struggled with software recognition software we can understand the problem that Google was facing. Their new technology should make the process quicker.

Comments welcome.
