Abstract
Systems and methods for automatically focusing an image capture device on a page of a document object. A predetermined light pattern is projected onto the page being imaged. The light pattern varies as a function of the separation of the page being imaged from the end page. The light pattern projected onto the page being imaged is sensed. Based on the sensed light pattern, the image capture device is focused on the page being imaged.
