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.
Claims14
A system comprising:
- a line scanning camera configured to capture images of film located in a scanning area;
- a supply reel motor that rotates a supply reel to supply the film from the supply reel for scanning by the line scanning camera;
- a take-up reel motor that rotates a take-up reel to collect the film on the take-up reel after scanning by the line scanning camera;
- a plurality of capstan motors that rotate a plurality of capstans to direct the film from the supply reel, across the scanning area, and to the take-up reel;
- and
- a control system, the control system configured to:
- receive position information from the supply reel motor, the take-up reel motor, and at least a subset of the plurality of capstan motors,
- dynamically adjust the position information by adding or subtracting adjustment information to the position information,
- provide the dynamically adjusted position information to a plurality of controllers, and
- generate, using the plurality of controllers and at least one capstan motor profile generator, control signals for the supply reel motor, the take-up reel motor, and the at least a subset of the plurality of capstan motors,
- wherein control signals for at least two of the supply reel motor, the take-up reel motor, and the at least a subset of the plurality of capstan motors are generated using a single capstan motor profile generator,
- wherein at least one of the plurality of controllers includes a dynamic resolution adjuster configured to determine internal measurements of a tension of the film,
- wherein at least two of the plurality of controllers share a single dynamic resolution adjuster and receive inputs from the single capstan motor profile generator.
