intercepts it and responds according to the Contrast Out of Range action setting in the
Warnings tab. The detected contrast value is listed on the status bar in the VRS
Interactive Viewer.
For example, if the Contrast Out of Range threshold is 15 on the Warnings tab, VRS
accepts any image with a contrast value ranging from 35 to 65. The range starts at 35,
which is 15 less than 50, and it ends at 65, which is 15 more than 50. Therefore, an
image with a contrast value of 25 would fall outside the valid range and generate a
warning. VRS would respond by taking the action listed on the Warnings tab for
Contrast Out of Range. Refer to Figure 3-14 on page 44.
Color Confidence Out of Range
Use this threshold to define the valid range for color confidence values. When a
Use this threshold to define the valid range for color confidence values. When a
document is scanned, VRS evaluates the image to determine if it is color or bitonal.
VRS also determines how confident it is that the correct assessment was made. The
confidence level is expressed as a percentage that appears in the status bar of the VRS
Interactive Viewer.
VRS compares the percentage to the user-defined acceptable value, which is the Color
Confidence Out of Range threshold setting on the Warnings tab. Based on this real-
time evaluation, VRS either accepts the image and allows it to be passed on to the
scanning application, or intercepts it and responds according to the Color Confidence
Out of Range action in the Warnings tab.
For example, if the threshold is 50 on the Warnings tab, VRS accepts any image with a
color confidence value of 50 or higher. Therefore, an image with a color confidence
value less than 50 would fall below the valid range and generate a warning. VRS
would respond by taking the action listed on the Warnings tab for Color Confidence
Out of Range. Refer to Figure 3-14 on page 44.
Errors Tab
The Errors tab lists exception conditions such as errors caused by equipment conflicts
or paper transport issues, along with the VRS response to each condition.
Note
The list of error types on the Errors tab may vary, according to the scanner that
you are using with VRS.
In the Action column, select the desired VRS response for each error type. To change
the setting, click in the Action box and select the new setting from the list.
