You might be jumping to conclusions here, Tony.  If the white light 
source used has IR in it, they may still be using an IR channel, but 
doing it as a separate scan.  It is possible Honda was simply comparing 
this to Nikon, which uses R, G, B and IR LED info.  Perhaps it was 
easier to incorporate the IR scan separately rather than do it per scan 
line, as might be done with other non-LED scanners.

Again, some have mentioned that doing this two scan process might lead 
to somewhat off registered scans, and if this is the case, it could make 
an inferior IR overlay for dust and scratch removal.
