Digital ICE?
The award-winning Digital ICE technology automatically removes surface
defects, such as dust and scratches, from a scanned image. Digital ICE
differentiates itself from software-only solutions because it does not
soften, blur or otherwise alter any underlying details or composition
of the original image. Instead, ASF's patented Digital ICE technology
works from within the scanner, during the scanning process, to provide
users with a clear, authentic base image that improves the original
imagex. |

Announcing the End of Dirty Images
|
Digital ICE
eliminates the effects of scratches, dust, fingerprints and even mold
when scanning negatives, positives or slides. Unlike competitive
technologies, Digital ICE does not remove the detail content of the
image. This is accomplished by obtaining information about the nature
and location of surface and near-surface defects as an image is scanned.
During the typical scanning process, red, green and blue image
information is gathered utilizing RGB channels. Digital ICE scanning
uses a fourth channel, referred to as the defect or "D" channel,
to collect the defect information.

former Texas congresswoman, was taken over 25 years ago. The negative
has several defects including a large scratch. |

Once the surface-defect
information is collected through the D channel, complex,
proprietary algorithms are used to erase the defects without degrading
the image. These algorithms accept Digital ICE four-channel RGBD as
input to produce three-channel, RGB, surface-defect-free images as
output. The three-channel RGB output resulting from the application of
Digital ICE technology is like any other RGB image and can be used by
higher-level applications without any special accommodation by the
third-party software. |
