Now that I've started reading the patent details, it is obvious those drawings don't
exactly paint the full picture :-).
I didn't notice this before (did they just change the site?) but there is a link to
the patent from that site

Precisely!

Yes, it is made with National Semiconductor, and it is considered
equivalent to a 7 meg in current bayer pattern technology, although it
actually has 3.53 "million pixels".
Due to the fact that each pixel records all three colors RGB, using
color filtration/separation caused by the natural charac
If the lines are flickering/moving, then I would suspect either the monitor, video

If they are stationary, and you have verified that they are not in the file, I would
suspect your video card driver. The following q's may help you to identify the fault:

Al,
Thanks for the suggestion. I've just tried this with my Nikon LS4000 -
turning off color management and setting the preview gamma to 1.0 so that
the raw tif file is suitable for Vuescan. Then I used Vuescan to color
process the file, and lo and behold, the final image is better coloured and

I'm scanning some negative strips with my Nikon LS-40, but VueScan is
taking a fair while to process/save them on my lowly laptop. After a
certain amount of time (5 minutes? I've not timed it) the scanner seems
to automatically eject the film. That would be no problem, except that

IMO software makes only a secondary contribution, or attempt to improve how
