5.2 SCANNING PARAMETERS & IMAGE CONTROL
Resolution: The number of dpi (dots per inch) that the DS310F
uses for a scan. Usually the greater the number, the
higher the resolution. Yet up to a certain level, the
resolution will not be visually increased but the disk
space will be increased.
Brightness: Adjusts the lightness or darkness of an image. The
higher the value, the brighter the image.
Contrast: Adjusts the range between the darkest and the
lightest shades in the image. The higher the contrast,
the bigger the different gray scales.
