How to Configure
1. Set
GradationCompressionMode
to
On
to enable the function.
2. Select a value for
GradationCompression1stKneePoint
to indicate where to start applying
compression on the intensity values coming from the sensor. The knee point is specified as a
percentage of the maximum digital value of the 8-bit compressed output (255).
Caution:
Selectable % values are 0, 6.25, 12.5, 25, 50, 100, 200, 400, and 800. However, if
the first knee point is set at 100 or higher, there is no room for compression to occur.
Therefore, first knee point should always be set to 50 or lower. See
3. Select a value for
GradationCompression1stGain
in order to set the slope angle at the first
knee point. Available values range from 0 dB (no compression) to -66 dB.
4. Use
GradationCompression2ndKneePoint
and
GradationCompression2ndGain
to define
an additional compression segment.
Examples
The following examples show how Gradation Compression knee points and gain can be calculated
and applied.
