[Threshold]
By clicking
, you can access the [Threshold] dialog box.
If [Black and White] is selected in [Color Mode], the Color Settings buttons will
become the [Threshold] button.
NOTE
•
The brightness of color and grayscale images are expressed as a value between 0 and
255 but brightness of black and white images is expressed in terms of either black or
white including the parts of an image which are a color between the two. The boundary at
which black and white is divided is called Threshold.
•
By adjusting the threshold, you can sharpen characters in a text document and reduce
back-printing such as in newspapers.
[Threshold Level]
Move the [Threshold] slider to the right to increase the threshold value
and thus reduce the white areas (black areas will increase). Move the
slider to the left to decrease the threshold value and thus increase the
white areas (black areas will reduce). You can also enter a value (0 to
255).
[Reset]
Resets all the current settings to their default values.
