FILM TRANSPORT APPARATUS CONTROLLER AND RELATED METHODS
20210044724 · 2021-02-11 ·

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.

Film scanning method and apparatus determining image offset from imaged film transport perforations
10681249 · 2020-06-09 · ·

Digitization of film, and more particularly film scanning, includes capturing light transmitted through the film so as to acquire a digitized image. This includes a captured frame comprising a digitized image of at least a portion of at least one image frame of a sequence of image frames, and at least a portion of one or more transport perforations. The method can further include determining an image offset corresponding to at least the captured frame on the basis of a comparison between at least one detected edge in the captured image and a corresponding datum location. A signal representing the image offset can be generated to enable alignment of at least the captured frame.

Perfless and cadenceless scanning and digitization of motion picture film

Motion picture film is scanned by high-resolution, continuous sprocketless scanner, producing a first sequence of digital images each representing a plurality of motion picture frames and perforations (perfs) of the film input. The first sequence of images is processed using a processor running an analysis and extraction algorithm, producing a second sequence of images each including a single, edge-stabilized frame of the motion picture.
