9.1.12.5 Gain Control Menu
Once inside the Gain Control Configuration menu it is
possible to set one of the following parameters:
1.
Algorithm:
Sets the type of automatic gain
control (AGC) to optimize the image. It is
possible to choose between the following
algorithms:
•
Automatic:
Automatically sets the
contrast and brightness of the image
when environmental conditions change by
equalizing the grey scale histogram. The
image can be modified by changing the value
of the ITT Mean, Max Gain and Plateau Value
parameters. This is the default algorithm
and it is recommended for normal use of the
thermal camera.
•
Once Bright:
The set brightness level
represents the mean of the brightness values
of the image when this parameter is selected.
The image can be modified by changing the
value of the Contrast parameter.
•
Auto Bright:
The set brightness level
represents the mean of the brightness values.
Such level is updated in real-time. The image
can be modified by changing the values of
the Contrast and Compensation parameters.
•
Manual:
The contrast and brightness levels
are manually set by the user.
•
Linear Histogram:
Contrast and brightness
of the image are optimized using one linear
transfer function. The image can be modified
by changing the values of the ITT Mean and
Max Gain parameters.
•
Information-based:
The information-based
algorithms retain more grey tones for the
portions of the image with more information,
assigning fewer grey tones to the portions
of the image with less information content.
Information-based algorithms exclude the
pixels from the histogram equalization
process if their value is below the information
threshold.
•
Information-based Equalization:
The
information-based Equalization algorithm
includes all the pixels in the histogram
equalization process regardless of the scene
information content. The algorithm weighs
each pixel according to the value of the
information threshold.
2.
Plateau Value:
Sets the maximum pixel value
which can be found in a grey scale.
3.
ITT Mean:
Sets the mean point on a grey scale.
4.
Max Gain:
Sets the maximum gain of the AGC.
5.
Contrast:
Sets the contrast level of the image.
6.
Brightness:
Sets the brightness level of the
image.
7.
Compensation:
Sets the brightness
compensation level of the image.
8.
ACE Threshold
: Sets the threshold for Active
Contrast Enhancement (ACE).
