Abstract
A digitizer is provided with a camera, a movable stage and a control device. The stage may be moved by first and second linear motors such that the digitizer can be used in non-stationary or vibrating environments. A bundle of fiber optics is used to constantly illuminate a patch of an image to be digitized. Also, a control device is provided between the camera and the first and second linear motors for controlling the camera and the positioning of the stage. Various sized images can easily be digitized while memory requirements are kept low and speed is kept high. This digitizer provides for an adaptive dynamic range as well as an improved contrast sensitivity. Also, a mechanism for correcting the effects of skew and keystoning is provided which enables collection of seamless mosaics.
