Hi Ernst,

A film scanner does not use a Bayer pattern filter.  They use a linear
sensor, either tri-linear (one line for each color) or uni-linear (three
passes, with a new filter for each color), or...there is a scanner on the
market (Nikon) that changes the colors of the light source and uses a
tri-linear sensor...but because of bugs, uses it in a uni-linear mode and
takes three exposures for each line, one exposure per color...

Regards,

Austin
