1) Advanced
text
enhancement
In this mode, a histogram of brightness level
for each block within the scanned data is
calculated, and an optimum slice level is
determined to binarize the pixels.
Binarizing in this way removes the
background, for example, from behind text
printed on a background.
For example, as shown in the image in Fig.
2-517, a histogram for each block is calculated,
and the optimum slice level is determined to
binarize the pixels.
