■ [Auto Image Type Detection Settings] Dialog
Box
This dialog box appears when you select [Auto Color
Detection], and enables you to make settings for detecting
whether scanned images are in color or black-and-white,
and select the mode to use when an image is detected as
black-and-white.
Color Saturation/Proportion of Color
These settings are for judging whether a document is in
color.
Depth of color in documents is detected by [Color
Saturation], and [Proportion of Color] is used to judge a
color document.
IMPORTANT
• Changing these settings is not normally necessary. Change
them only if you want a document of light colors to be judged
to be a black-and-white document.
• Select [24-bit Color] if color documents are judged to be black-
and-white documents with the default settings.
[Mode in case of binary]
Select the scanning mode when a page is judged to be
black-and-white.
