Infrared Against Scratches

Besides the RGB illumination unit, the ARRISCAN uses an additional
infrared illumination channel to identify lm defects. Since lm color
dyes are transparent for infrared light, the ARRISCAN sees only lm
defects (such as dust, lint and scratches) in the infrared image, which
means such defects can quickly be isolated and corrected.
Kodak’s DIGITAL ICE Technology uses the infrared channel of the
ARRISCAN to automatically remove dust, scratches and blemishes from
a scanned image. First, DIGITAL ICE identies all defects in the image
and then reconstructs the true color information wherever possible;
the number of blemishes is thereby reduced signicantly. Remaining
defects that are too severe to be reconstructed perfectly are marked
in an additional defect map, which can either be stored as a matte or
embedded into the scanned image. Downstream workow productivity
both in terms of labor and time is signicantly improved.
Optimized for the ARRISCAN image processing chain, DIGITAL ICE
is seamlessly embedded into the data path and is applied to the images
on-the-y while scanning.
The DIGITAL ICE package is available as an additional option for the
ARRISCAN.
