ABSTRACT:
A hand-held scanning device employs apparatus for varying the depth of field of the scanning device. The scanning device comprises a gun-shaped housing for comfortably fitting within the hand of an operator. The scanning device is actuated by a finger-activated trigger, which moves a CCD sensor on an image plane as the trigger is pulled. In this manner, focusing for large depth of field applications is achieved.
