Abstract
The present invention provides a method, apparatus and system that pre-scans and pre-treats film for improved digital film processing. The apparatus for use with the invention includes, generally, a sensor for detecting one or more imperfections on the film and a microprocessor connected to the sensor that determines the amount and extent of imperfections of the film based on one or more reference readings. The present invention may also include a tape dispenser, cleaning rollers, a blower or vacuum to remove and/or correct any imperfections in the film. One embodiment includes a cleaning system for a particle removal member which removes particles from film. The cleaning system is relatively movable and selectively contactable with the particle removal member to clean particles from the particle removal member.
