Image Acquisition
¾
Color Mode
This parameter can be switched between
RGB = 0
(Default) and
Luminance = 1
.
In
RGB
mode the
Unsharp Masking
is calculated individually for each color
channel. The color saturation and color of sharpened structures may be
changed and color noise may occur.
If this is unwanted, it is possible to switch to
Lumincance
mode. Here, the
sharpness calculation is only carried out on the brightness signal determined
for this purpose (
Lumincance
). This mode does not display any color noise
and alters the color saturation accordingly.
¾
Radius
and
Strength
Radius
determines the width of structures that are to be sharpened.
A small radius intensifies smaller details. If the radii are too large, halo effects
may occur at the edges.
Radius
and
Strength
interact. A smaller radius
allows a greater strength and vice versa.
At a resolution of 1388 x 1040 pixels, value 2 is an appropriate setting. If you
switch to a higher resolution for the same image, you can increase this value
in order to obtain an impression of the image comparable to the basic
resolution.
Value range: 1-11
The radius is stated in pixels: value 1 = 3 pixels and value 2 = 5 pixels
¾
Auto Contrast
Increasing the contrasts changes the distribution of intensities in the image.
As a result, the histogram becomes broader.
This parameter limits the change in the distribution of intensities during the
sharpness calculation. The purpose of this is to try to maintain the existing
minimum and maximum values of the input image.
This parameter can be switched between On=1 (Detault) or Off=0.
