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 to OK.
  • The values of parameters WBO_GainR, WBO_GainG, and WBO_GainB are updated with the calibration results.
  • The White Balance Operator is reconfigured with the new settings.
At the completion of an unsuccessful calibration process:
  • The value of the parameter WBO_Status is set to NOT_OK.
  • The original values of parameters WBO_GainR, WBO_GainG, and WBO_GainB are restored.
  • The White Balance Operator is reconfigured with the original settings.
