Advanced Color Processing
Overview
If your scanning application is set to color mode and you are using a Böwe Bell +
Howell Spectrum II series scanner, your VRS installation will include advanced color
image processing options. These options are accessible from the Color tab on the VRS
Interactive Properties dialog box.
You can use the options on the Color tab to implement features such as Automatic
Color Detection and Color Background Saturation. Additional options related to color
processing will also be available from the VRS Administration Utility and the
Analysis tab. For more information, refer to Color Confidence Out of Range Warning on
page 99 and Color Information on the Analysis Tab on page 100.
Automatic Color Detection
Automatic Color Detection is the ability to detect and process a color image, or color
content within an image. VRS can process a batch that contains both color and non-
color images; the non-color documents are output as bitonal images. Automatic Color
Detection includes a Color Object Size Detection setting that you can use to adjust
sensitivity to documents that include small amounts of color.
With Automatic Color Detection, VRS is capable of outputting a document or batch of
mixed image types as color or bitonal, based on automatic recognition of the image
content. You can configure Automatic Color Detection to detect or ignore small
amounts of color, or pages printed on color paper.
If you do not enable the Automatic Color Detection feature while scanning in color
mode, VRS will process every document as a color image.
Note When Color Detection and Blank Page Thresholding are both enabled, be aware
that a document detected as bitonal may not meet the criteria required to perform
Blank Page Thresholding.
