from occurring oscillations.
Automatic contrast control
The contrast of the Goldeye G/CL can be adjusted automatically by applying the
relevant auto contrast settings. The adjustment is based on the present signal
values of pixels within the image.
By default, the automatic contrast control is switched off, however, it is possible to
have the automatic contrast control applied in several ways:
•
Apply it to the whole image.
•
Apply it to a defined area of interest. To apply the automatic contrast to an
area of interest, use the
AutoModeRegion
features to define the area.
Controlling the intensity of contrast
Using the
ContrastAutoIntensity
features, it is possible to adjust the intensity
of contrast applied. Those features represent an upper and lower threshold of
contrast intensity. In combination, they act as follows:
•
If both features are set to higher values, the affected area of the image turns
brighter.
•
If both features are set to lower values, the affected area of the image turns
darker.
•
If the difference between the set values for both features increases, contrast
intensity increases (the black and white spots within the affected area are
increasing in number).
