Parameters and commands
Exposure feature mode (bit group f)
The exposure feature mode allows to switch between Standard mode, Enhanced
full well mode and Permanent exposure mode.
Standard mode
Bit group: f
Weight: 0
Enhanced full well (3T) mode
Bit group: f
Weight: 10
The full image shutter is not available in this mode. Instead, the sensor operates
in rolling shutter mode, the effective shutter time equals the image duration.
For that reason, a synchronized strobe light is recommended.
