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.
Claims18
A system, comprising:
- a processor;
- a dynamic resolution adjuster configured to determine internal measurements of a tension of a film;
- and
- a memory including instructions that when executed by the processor configure the system to:
- scan the film with a line scanning camera;
- receive, from a motor used to advance the film between a supply reel and a take-up reel, a plurality of rotational position measurements at a plurality of times while scanning the film;
- generate a control signal for the motor based on an associated rotational position of the motor;
- and
- in response to detecting an inconsistency in scanning the film:
- calculate an offset factor for the associated rotational position of the motor based on (i) a measurement of the inconsistency and (ii) the plurality of rotational position measurements associated with a time at which the inconsistency was detected by the line scanning camera;
- and
- adjust the associated rotational position of the motor via the control signal including the offset factor.
