NOTES: When a THR2 board is installed on the host PC, only the Hardware –
Best Binarization/High Speed option is available for selection.
Binarization is supported only when the scanning resolution is 150
dpi. The binarization options are not available when the resolution is
set to 100 dpi.
Adjusting the Threshold and Contrast settings in the Filters tab
will affect binarized images in the same way as black-and-white
scanned images.
Binarized images are upscaled from 150 dpi color images to 200 dpi
and are stored as Group 4 TIFF files in Capture Software.
Binarization takes place after color deskew and auto-crop (when
enabled). Therefore, Capture Software does not perform deskew/
auto-crop processing on binarized images.
Binarized image retention and display —when binarization is enabled, the
following drop-down list of image retention options is available for selection:
• Keep Color & Bi-tonal—displays and saves to disk both the color “parent”
image and the binarized image. This is the default selection.
• Keep Color only—displays and saves to disk only the color image. The
binarized image is discarded. Use this option when binarization is used only
for the purposes of reading bar codes or patch codes on color images.
• Keep Bi-tonal only—displays and saves to disk only the binarized image.
The color image is discarded.
Binarized images are displayed on-the-fly during scanning with their “parent”
color images. In general, binarized images are displayed before the color
images. Capture Software will always try to preserve a Front/Rear image
relationship when binarization is enabled. As a result, you can expect the
following image order for these scenarios:
NOTE: When auto-deletion of images is enabled in the image setup along with
Binarization, the binarized image size is compared against the byte
threshold . Both the binarized and the color “parent” images will be
deleted when the binarized image size falls below the byte threshold.
