Not in this case of the Mustek.
They would be daft to do it that way, but they are real clever :-)
WHY would anyone not use the whole sensor? that makes no sense whatsover.
You get much better results rescaling 2048xsomething to 640x480 even
if just for bayer pattern averaging.
Also you get better light sensitivity, and better optical details.

No need to prove anything, reality is.

Of course not, 265 x something rescaled to 640x480 never gives more then
256 x something detail.
That was not the issue.
