Density
(for X-ray mode only)
Image density is measured from image brightness with optical densitometers.
Optical density range determines difference between lightest and darkest colors
which optical sensor is capable to recognize. The minimum and maximum
values of density capable of being captured by a specific scanner are called
Dmin (minimum density, lightest tone) and Dmax (maximum density, darkest
tone). If the scanner's Dmin were 0.2 and Dmax were 4.2, its dynamic range
would be 4.0. Dmax implies unique image tone values are distinguishable, and
not hidden by electronic noise. Great dynamic range can detect greater image
detail in dark shadow areas of the image, because the range is extended at the
black end.
Therefore, the value of density is directly related to image quality. The higher
value of density, the more light the image will be.
None
None of the density settings will take effect to the image.
Automatic
This automatically optimizes the density capture range of the image by making
adjustments to the Dmin and Dmax values of an optimized range.
Using the Density,
Click the arrow button next to the Density box, and choose your setting from
the list box.
Note: The Density function is available only in the Settings window when the connected
scanner is supported by this function (e.g., Medi-3200, Medi-7000).
