Abstract
Methods and systems are presented for controlling a film transport apparatus of a film reel scanner. In one embodiment, a system is provided including a line scanning camera, a supply reel motor, a take-up reel motor, and a plurality of capstan motors. A control system may then be configured to receive and dynamically adjust position information from these motors. The control system may then provide the dynamically adjusted position information to a plurality of controllers, which may then generate control signals for the supply reel motor, the take-up reel motor, and the at least a subset of the capstan motors.
