Infrared Against Scratches
Besides the RGB illumination unit, the ARRISCAN uses an additional
infrared illumination channel to identify film defects. Since film color
dyes are transparent for infrared light, the ARRISCAN sees only film
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 identifies all defects in the image
and then reconstructs the true color information wherever possible;
the number of blemishes is thereby reduced significantly. 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 workflow productivity
both in terms of labor and time is significantly 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-fly while scanning.
The DIGITAL ICE package is available as an additional option for the
ARRISCAN.
