Abstract
A system for electronically developing an image captured on a film with two or more image capture layers. A developing solution is applied to the film and the film is illuminated by two lights on opposing surfaces. A scanner captures the light reflected from the film by each light source. The two digital images are combined on a pixel-by-pixel basis to form a final image. An alternate embodiment includes a third scanner to capture light transmitted through the film in order to form a third digital scan image which is then combined on a pixel-by-pixel basis with the other two images to form the final image. The invention provides a method for creating an image digitally without first creating an image in the film itself.
Claims4
A system for electronically developing an image captured on a film having two or more image capture layers, the system comprising:
- development means for applying a developing solution to said film;
- a first light source for illuminating said film with a first light;
- a first scanner for digitally capturing said first light reflected from said film during development to form a first digital scan image having a plurality of pixels;
- a second light source for illuminating said film with a second light, said second light source oriented to scan a surface of said film opposite a surface scanned by said first light source;
- and
- a second scanner for digitally capturing said second light reflected from said film during development to form a second digital scan image having a plurality of pixels;
- digital image combination means for forming a final image by digitally combining a pixel from each of said digital scan images to form a final image pixel.
