NOTE
The brightness of color and grayscale images are expressed as a
value from 0 to 255 but the 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".

frames, settings for the whole preview area are saved.
You can also recall the saved settings and apply them to the
selected frames or the whole preview area.

for each Color Settings item. Even after the
registered settings are applied, [Custom]
resumes automatically if you change any
setting or make adjustments to the selected
cropping frame.

dialog box ([Add/Delete Threshold Settings]
