Abstract:
A photographic film scanning system for scanning a film strip containing a plurality of photographic images and for creating a corresponding plurality of digital representations of the photographic images, the system comprising:a light source for projecting light through the film strip; a light sensor for sensing the light projected through the film strip and for generating pixel data, the light sensor located at a first light sensor position; a film drive for advancing the film strip between the light source and the light sensor; a lens located between the film strip and the light sensor for directing the light projected through the film strip onto the light sensor, the lens located at a first lens position; adjustable resolution means for changing the position of the lens to a second lens position and for changing the position of the light sensor to a second light sensor position, wherein the change in positions of the lens and the light sensor results in a change in the scanning resolution; means for generating a digital image of the film strip from the generated pixel data, the digital image of the film strip including the plurality of digital representations of the photographic images; and means for locating the plurality of digital representations of the photographic images in the digital image of the film strip.
