Table 3-3 lists the actions that you can select as responses to the warnings on the
Warnings tab.
Brightness Out of Range
Use the Brightness Out of Range threshold to define the valid range for brightness
Use the Brightness Out of Range threshold to define the valid range for brightness
values. When a document is scanned, VRS evaluates the resulting image to determine
its brightness. Then, VRS compares the actual brightness value to the user-defined
acceptable range. The acceptable range is determined by starting with 50 and adding
and subtracting the Brightness Out of Range threshold value listed 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 Action setting in the Warnings tab. The detected value for brightness is reported
on the status bar in the VRS Interactive Viewer.
For example, if the Brightness Out of Range threshold is 10 on the Warnings tab, VRS
accepts any image with a detected brightness value ranging from 40 to 60. The range
starts at 40, which is 10 less than 50, and it ends at 60, which is 10 more than 50.
Therefore, an image with a brightness value of 70 would fall outside the valid range.
VRS would respond by taking the action listed on the Warnings tab for Brightness
Out of Range. Refer to Figure 3-14 on page 44.
Contrast Out of Range
Use the threshold to define the valid range for contrast values. When a document is
Use the threshold to define the valid range for contrast values. When a document is
scanned, VRS evaluates the resulting image to determine its contrast. Then, VRS
compares it to the user-defined acceptable range. The acceptable range is determined
by starting with 50 and adding and subtracting the Contrast Out of Range threshold
value listed 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
