7.12.13 Category:HDRTonemappingCurveControl
This category contains the Baumer HDR tone mapping curve control features.
With tone mapping, the HDR (High Dynamic Range) image is converted to an LDR (Low
Dynamic Range) image.
Notice
The internal processing is done on 12 bit, therefore the HDR tone mapping is always
applied to 12 bit LDR.
Three presets are available (selectable via HDRTonemappingCurvePresetSelector).
Additionally, you can also create your own transfer function for the tone mapping by set-
ting values of:
▪ HDRTonemappingCurveOffset
▪ HDRTonemappingCurveGradient
▪ HDRTonemappingCurveGridpoint
for each of the 16 indices of HDRTonemappingCurveGridpoint.
The following graphic shows an example, how each value inuence the characteristics of
the HDR tone mapping curve.
