If it has ICE, the ad copy will say so for sure.
ICE is a technology developed by Applied Science
Fiction (yep, that's really their name) and licensed for
use in various scanners -- mostly film scanners, but
lately in some flatbeds also.
In any case, the license to use and implement ICE
costs some $$ so you can be sure that if a scanner
has it, it will say so.
ICE involves a separate IR (infrared) illumination
channel, and firmware that reads the slide or
negative through the CCD with the IR illumination.
That's about all I know other than: it works, and
it's as close to magic as anything I've seen in the
digital imaging game. It has saved me hundreds
of hours of spotting and scratch-removing in
Photoshop.
PS: Appartently Canon has developed a similar
technology in their film scanners that somehow
skirts the ICE licensing issue. As a result, Canon
calls their scheme "FARE" although I believe it
works by similar principles as ASF's ICE.
