Abstract
A method, system and process for reflecting a light on both sides of a film and developing the film to produce a digital image by scanning an image on the film as it develops and creating a digital representation of the image on the film.
Claims8
A scanner for producing a digital color image, comprising:
- (a) means for capturing first reflected light reflected from the front of a multilayer film as said multilayer film travels through said scanner;
- (b) means for capturing second reflected light reflected from the back of the multilayer film;
- (c) means for capturing transmitted light passing through the multilayer film;
- (d) means for storing a plurality of digital images each formed as a plurality of pixels from one of said captured first and second reflected light and said transmitted light;
- and
- (e) means for creating a digital color representation of the image on the multilayer film by combining said plurality of digital images on a pixel by pixel basis.
A method for electronically creating an output image from an image containing film having two or more image recording layers, the method comprising the steps of:
- directing a light source toward a first surface of the film;
- capturing light reflected from the first surface of the film;
- storing the captured light as a first digital representation of the image having a plurality of pixels;
- directing a second light source toward a second surface of said film, the second surface and the first surface forming opposite sides of the film;
- capturing light reflected from the second surface of the film;
- storing the captured light as a second digital representation of the image having a plurality of pixels;
- and
- combining the stored digital representations on a pixel by pixel basis to produce the output image.
A method for electronically producing an image recorded on a film having two or more image recording layers, the method comprising the steps of:
- directing a light source toward a first surface of said film;
- and
- capturing light reflected from said first surface of said film to form a first digital representation having a plurality of pixels;
- directing a second light source toward a second surface of said film, said second surface and said first surface forming opposite sides of said film;
- capturing light reflected from said second surface of said film to form a second digital representation having a plurality of pixels;
- and
- combining the digital representations on a pixel by pixel basis to produce an output image.
