Abstract
An optical scanning apparatus for retrieving digital electronic images representative of opaque objects. The apparatus is equipped with a reflective scanning platform for supporting an opaque object thereon. A scanning camera, equipped with a light source for illuminating the platform, is aligned to retrieve images from objects placed upon the reflective scanning platform. An object sensor included with the scanning camera detects the presence of such images. Using the sensor during scanning, provides automotive detection of the end of the object thereby reducing the scan time.
