Adjust the independent exposure control using either the GUI or the 3-letter commands:
CamExpert GUI
In the Camera Control Set
Parameter Value
Exposure Time Color Selector All, Red, Green, Blue, Mono (2k)
Exposure Time
Three-Letter Commands
In the Camera Control Set
Parameter Value
scl (Select Exposure Time Color Selector) Select 0-ALL, 1-Red, 2-Green, 3-Blue, 4-Mono (2k).
set (Set Exposure Time) Executes the command.
Note that the red and green exposure times must be set at least 1 µsec shorter than the blue exposure time .
The above restriction should not to be an issue for most applications, as commercial light sources
generally output less power at the blue end of the spectrum. If the Exposure Time Color Selector is set to
All , this criteria is automatically met.
Further note that the order in which the exposure time color selector values are entered is important.
When entering the exposure times using either the GenICam interface or the three-letter command
interface, checks are performed on the entered exposure times. If a blue integration time is entered that is
shorter than the green or red integration time, then an error condition will be indicated and the value will
not be accepted by the camera. The same is true if a red or green integration time is entered that is not
smaller by 1 µsec than the blue integration time.
Be aware that the above checking is performed on the value being entered against the values the camera
currently has set and therefore that the order that the values are entered is important. For example, if the
revised blue value is less than the current blue value, enter the green and red values first. If the new blue
value is greater than the current blue value, enter the blue value first.
