Abstract
The invention relates in general to providing greater accuracy in scanning and digital reproduction of images. More specifically, the invention acts to improve the precision of optical data by substantially eliminating sensor drift or “dark current” and acts to improve the accuracy in identification of the position at which various optical samples are taken by determining and correcting for the lag time inherent in initiating and executing a sampling operation.
