Hello,
the white shading picture must be all white. The picture you posted is
mostly
OK, but there is still some blue on the right. This is not a blocker, but it
will certainly have to be fixed to reach best image quality.
By averaging, I was thinking of the AVEENB bit of register 3 which
tells the
ASIC to delete extra data points or average them to produce data from higher
dpi.
Regards,
Stef
