[0 to 15 / 8 / 1 /step]
0: MTF Off
When the CCD converts the original image to electrical signals, the contrast
is reduced due to the influence that adjacent white and black pixels have on
one another as a result of lens properties. Typically, you will see very narrow
width and spacing between black and white areas. MTF corrects this
problem and emphasizes image detail.
6 Smoothing
Selects the level of smoothing for originals that contain
dithered images.
[0 to 7 / 4 / 0 / step]
0: Default (Off) → 7: Strongest
7 Brightness
Sets the overall brightness of the image.
[1 to 255/128/1]
1: Weakest ← 128: Default → 255: Strongest
8 Contrast
Sets the overall contrast of the image.
[1 to 255/128/1]
1: Weakest ← 128: Default → 255: Strongest
9 Ind. Dot Erase
Sets the level of independent dot erasure to improve
the appearance of background.
[0 to 7/0/1]
0: Default (Off) → 7: Strongest
10 Text Erasure
Sets the erasure level of textures. Set higher for
stronger effect, lower for weaker effect.
