■[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.

Chapter 8 ISIS/TWAIN Driver Settings

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.

Brightness and Contrast

Adjust the brightness and contrast when [Advanced Text Enhancement] or [Advanced Text Enhancement II] is selected for [Mode in case of binary]. For other modes, the brightness and contrast are set on the [Brightness] tab sheet.
