Feature value changes during streaming
Only some features can be adjusted while the camera is streaming, these include:
This list is not complete and will be updated in future document versions.
Value changes by feature interdependencies
The conversion between time and clock cycles affects control values. Features for
pixel format, bandwidth, ROI, exposure time, and triggering are related to each
other. Changing values for one feature can change values for another feature. For
example, frame rates can be reduced when
PixelFormat is changed subsequently.
Figure 89 shows the interdependencies.

Latencies
Consider that value changes become effective with latencies based on the sensor
and its operation mode (triggered or free run, shutter mode, frame rate).
