Selects the MTF filter coefficient in the main
scan direction for Text mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied.
[0~15/1]
As above, for sub scan
[0~13/1]
Selects the MTF filter strength in the main
scan direction for Text mode.
Select a higher number for a stronger filter.
[0~7/1]
As above, for sub scan
[0~7/1]
Selects the smoothing pattern for Text mode
when using binary picture processing mode.
A larger value could cause moiré to appear in
the image.
[0~7/1]
Selects the scanner gamma type for Text
mode when using binary picture processing
mode.
[0~6/1]
The following SPs adjust the image density
(brightness, contrast, and thresholds) for each
image density level (from 7 to 1) for Text
mode when using binary picture processing
mode. The settings are reflected in the
gamma table.
