Key points concerning Multi-Slope Mode:
Auto-Brightness mode must be disabled.
Exposure synchronization is automatically set to Reset Mode (lowers limit for maximum fps).
The exposure is not automatically returned to synchronous mode when Multi-Slope Mode is
disabled.
Sensor characteristics change above the knee point. Increasing the dynamic range above the
multiSlopeKneePositionY
setting implies a nonlinear sensor response.
Overall Analog Gain is reduced to 67% (models TS-M4096, TS-M3500, TS-M2500) of the
default gain when enabled, therefore increasing the pixel well capacity at the sensor level.
When used with a color camera, white balance will not be correct above the knee point.
Example Procedure for Multi-Slope Setup
Note: This example serves only as a guide to using the Multi-Slope feature. Every imaging
setup is a compromise between finite dynamic range, sensor signal-to-noise, and variable
lighting situations.
First adjust exposure time (and lens iris) such that all dark areas of the image are properly
exposed. Bright areas will be saturated in situations where the multi-slope function is required.
Enable Multi-Slope Mode (
multiSlopeSensorResponseMode
). With the default values for
multiSlopeKneePositionY
and
multiSlopeKneePositionX,
there will not be any obvious change at
this point.
