High resolution film scanner/telecine which uses a microlithographic diffuser laminate to aid in the reduction of visibility of surface imperfections in the film

摘要

A high resolution film scanner or telecine uses a microlithographic diffuser laminate (24) arranged adjacent the film. The diffuser diffuses a collimated light beam produced from a light source and the optics of a film scanner or telecine. This type of diffuser is inexpensive, yet produces a more uniformly distributed light intensity and aids in the reduction in visibility of surface imperfections such as scratches on the scanned film.
