7.5 Command AH - Activate One-Push Auto White Balance (AWB) - Shutter
By sending this command via the serial communication, the
shutter based
One-Push AWB function
is activated. The white balance function takes approximately 3 seconds to complete. During this
time the rear panel LED will show orange.
This function operates in two steps. First the red-to-green channel difference and the blue-to-green
channel difference are calculated separately. Then the exposure times of the blue and red channels
are automatically adjusted, to obtain the same output level on all three channels.
Settings:
0 = activate automatic process
Applicable modes:
Shutter-Select mode only
Associated functions:
Command WB
Note:
When color temperature of illumination exceeds the range of adjustment, proper white
balance may not be obtained.
The data can be stored in camera memory for use at next start up.
This function can work in external trigger mode.
The S/N ratio of the output will remain constant for all channels
