This enables a copying operation for a document consisting of a plurality of pages to be efficiently controlled.

The operator can subsequently choose the desired item triggering the camera system to automatically capture desired information from the item which is in turn communicated to an inventory control system. The camera system mitigates the requirement of a second individual to communicate information between the field and the operator.
