I agree, providing the system can calibrate to the current "state" of the
light source.

Hum.  Typically, I believe, auto-exposure would be merely setting the
setpoints, not varying the exposure time, but I don't know your
scanner/software...but I just want to point out auto-exposure MAY be a
misnomer.  Let me know what you think about that.
