Patent
CA 2093841
A method, system and process for a universal, multispeed film for use in conjunction with the production of a digital image by scanning an image on the film as it develops and creating a digital representation of the image on the film is disclosed. Unlike conventional colour film that typically has six layers but only three standard dye colours, the film of the subject invention assigns six dye colours among the layers. The processed film is scanned with a separate colour for each dye, giving for each pixel an equation of six variables. Solving this matrix separates the six dye images. Then, the dye image or blend is selected for each pixel which yields the most grainless representation. The resultant image is superior to current technology films over a wide range of effective film speeds.
