Abstract
A method and apparatus for providing localized control of film, allowing high speed and high resolution continuous digital scanning of the film. The method includes continuously and precisely transporting the film, capturing successive slit images, and storing the images. The apparatus includes the use of a drive system to control the transport of the media being scanned. In a preferred embodiment, a dual capstan drive system under the control of a single motor provides localized tension and location control for the continuous transport of the film to be scanned, the capstans comprising a metal shaft. The preferred embodiment further comprises pinch rollers immediately adjacent to the capstans, the pinch rollers comprising a metal shaft covered with an elastomeric material. As a result of the accurate localized control of the film, high speed scanning is possible.
