Resolution
The resolution is measured in dots per inch (dpi), which is used to represent the image detail in a
given area. The available resolution ranges from 50 to 19200 dpi. Generally, the higher the
resolution, the sharper and higher the quality of the scanned image. However, in some cases,
high resolution is not necessary because resolution is determined or limited by many factors:
image type, the original image resolution, the output device resolution, the available storage
space on your hard disks, etc.
Normally you should choose a resolution that matches the resolution of the output device. The
following list is our suggestion:
72 - 100 dpi for CRT Display
72 - 216 dpi for 9-pin Dot Matrix Printer
100 - 400 dpi for 25-pin Dot Matrix Printer
100 - 400 dpi for Facsimile
100 - 600 dpi for Laser and Inkjet Printer
You can adjust the resolution by using the scroll bar (moving the box, clicking the arrow icons or clicking on the space between
the box and the icon), directly keying in the value into the number box, or selecting a value in its drop-down combo box to the
desired resolution.
Brightness
Brightness refers to the intensity of light reflected from or transmitted through an image. The
larger the brightness value, the brighter the image appears. Brightness is indicated by a
percentage ranging from ¡V100 to +100, and is set to "0" as the default. You can either use the
scroll bar (moving the box, clicking the arrow icons or clicking on the space between the box and
the icon), key in the value into the number box or select a value in its drop-down combo box to
change the value.
