Scan Mode box
The Scan Mode box provides two scan modes: 24 bits
mode and 36 bits mode . The more bits used to
reproduce the image color, the more accurate the
scanner captures the colors of the original.
24 bits mode
In 24 bits mode, MiraScan uses 8 bits for Red, 8 bits for Green and 8 bits for Blue
to capture the colors of the original.
36 bits mode
In 24 bits mode, MiraScan uses 12 bits for Red, 12 bits for Green and 12 bits for
Blue to capture the colors of the original.
Resolution box
Resolution is used to decide how delicate the scanner
captures the original image.
When the original is scanned and turned into a digital
image, the scanner captures and records the image in
terms of pixels . The more pixels used to record an
image, the more delicate it seems. In this way, details
in the image may be represented more clearly.
Resolution is the density of pixels in a digital image and is usually measured by a
unit called dpi (dot per inch) . If you use higher resolution to scan an image, the
scanner will record the image with more pixels and the quality of the scanned
image improved. Below are two examples of one image scanned at different
resolutions:
Image scanned at 150 dpi Image scanned at 300 dpi
