Automatic Calibration Timing
The color calibration process takes place during the first acquisition phase of a MultiCam
acquisition sequence when the WBO_Mode
is set to ONCE
.
The White Balance Operator is disabled before the sequence starts.
The calibration process begins when the DMA transfer of the first acquisition phase is
completed. The first MC_SIG_SURFACE_PROCESSING
signal of the sequence is
delayed until the completion of the calibration process.
At the completion of a successful calibration process:
- The value of the parameter
WBO_Status
is set toOK
. - The values of parameters
WBO_GainR
,WBO_GainG
, andWBO_GainB
are updated with the calibration results. - The White Balance Operator is reconfigured with the new settings.
- The value of the parameter
WBO_Status
is set toNOT_OK
. - The original values of parameters
WBO_GainR
,WBO_GainG
, andWBO_GainB
are restored. - The White Balance Operator is reconfigured with the original settings.
