Control Speed
You can set the auto function speeds in a 0-100% range. This influences the control response
times. High speed (100%) causes a little attenuation of a fast-responding control and vice versa. The
control functions for average brightness and for color rendering use separate speeds.
In trigger mode, every frame is evaluated for automatic control. The freerun mode skips a number of
frames by default because in that mode, changes to the image parameters only become effective
after one or more image captures.
Skip Frames
With the Skip Frames parameter, you can select how many frames should be skipped in freerun
mode (default: 4). This parameter strongly influences the control speed. Choosing small values can
destabilize the automatic control.
Hysteresis
The automatic control feature uses a hysteresis function for stabilization. When the actual value is in
the range of (setpoint - hysteresis value) up to (setpoint - hysteresis value), control is temporarily
disabled. It is reactivated when the actual value drops below (setpoint - hysteresis value) or exceeds
(setpoint + hysteresis value). If the hysteresis value is increased, the achieved target value is
maintained for a longer time in case of lighting changes. This makes the automatic control more
sluggish, but can be useful in some situations.
