High Dynamic Range mode (ICaterogy: Multislope)
6.13
In the camera, a high optical dynamic range can be realized setting the camera to a non-linear
response. To be more precise, the response can be piece-wise linear with up to 3 slopes (see figure
6.7).
Multislope response
Figure 6.7:
Basically the multislope response serves as a white compression, still enabling contrast in parts that
else would be saturated. For high exposures, this ensures contrast in bright part of the scene that
would otherwise saturate. An example is in figure 6.8.
