The High Dynamic Range 3D Feature (HDR-3D) of C2-
2040(HS)-GigE
One of the most powerful features of C2-2040(HS)-GigE is the HDR-3D (High Dynamic Range)
functionality, which allows scanning materials and surfaces with inhomogeneous reflection properties.
Using HDR-3D the dynamic range of image intensity is extended up to 90dB, thus avoiding intensity
saturation.
The HDR-3D comprises two independent sensor functions:
Multiple Slope Function
The aim of the Multiple Slope function is to avoid the saturation of pixels during sensor chip exposure.
This high optical dynamic range is achieved by using a piecewise linear response. The intensity of
illuminated pixels, which reach a certain level, is clipped, while darker pixels remain untouched. The
clipping level can be adjusted 2 times within one exposure time to achieve a maximum of 3 slopes in
the response curve. The points of the curve, where the slope changes, are called “knee points”. The
latter are defined through the setting of clipping levels for the intensity (thresholds) and time points
within the exposure time. These parameters can be adjusted using the Genicam registers
ExposureSlopeDuration and ExposureSlopeThreshold of the AcquisitionControl (XML grid visibility must
be set to “Expert”). A knee point times is defined as percentage of the overall exposure time. A
clipping level is defined as percentage of the maximum sensor intensity (saturation).
