Digital Ice Technology
How cool is Digital ICE technology?
Old film and slides are often covered with dust and scratches. Epson
scanners are able to remove these defects during scanning with Digital
ICE technology.
Digital ICE technology uses infrared light, which is able to detect
dust, hairs, finger prints or scratches. As infrared light is invisible
it cannot reproduce the colour information of the photo and therefore
only delivers the defect information to the scanner software.
So how does the technology work?
The photo is illuminated by the cold light lamp and the colour
information of the image is captured and delivered to the scanner
software. The photo is illuminated by the infrared lamp and only the
defect information is captured and delivered to the scanner software.
The two images (colour information and defects) are compared and the
defects are removed by means of algorithms. The result is an image
without defects.
