[Auto Color Detection Settings] Dialog Box

This dialog box appears when you select [Auto Color Detection], where you can make settings for detecting whether scanned images are color or black and white, and select the mode to use when an image is detected as black and white.

Color Sensitivity/Color Pixel Ratio

These settings are used to determine whether a document is a color document. The scanner detects document colors according to the color sensitivity setting, and determines that the scanned document is a color document based on the color pixel ratio.

☞Usually, the default settings can be used without change, unless you want to force the scanner to recognize a heavily colored document as a black- and-white document.

☞If a color document is detected as a black-and-white document with the default settings, select [24-bit Color]. When [Auto Color Detection] is selected, [Hi-Speed Text Enhancement] cannot be selected.

Mode in case of binary

Select the scanning mode when a page is judged to be black and white.

☞[High-Speed Text Enhancement] is disabled when [Auto Color Detection] is enabled.

Brightness

This control adjusts brightness when [Advanced Text Enhancement] or [Advanced Text Enhancement II] is selected with Black and White mode. For other modes, brightness is set on the [Brightness] tab sheet.

Contrast

This control adjusts contrast when [Advanced Text Enhancement II] is selected with Black and White mode. For other modes, contrast is set on the [Brightness] tab sheet.
