8.2.2 Setting the operation point automatically
NOTE
The position of the white reference mark (control zone) and the target gain
value for the control zone are used as specified in the setting (see section
9.3)
This operation only takes place in the current selected setting.
This function has to receive line data inside the camera. If the camera is
set to line trigger or encoder mode and the transport is not moving, an
error occurs.
Set the camera to internal line trigger.
1
Prepare the setup for the operation.
Make sure that black-level correction is enabled (see section 9.5.1)
2
On the toolbar, click
Perform white balancing
.
3
A dialog box is shown:
If you want to use the determined gain values as startup values (recommended), click
Yes
. Otherwise click
No
.
If the process succeeds,
White balancing succeeded
appears in the message box.
Possible errors:
White balancing error occurred. Error code No: 0x10D: no reference data
Camera is not in free-running mode (line and/or frame), but there are no trigger signals
and thus no reference data are available.
Adapt your configuration accordingly.
White balancing error occurred. Error code No: 0xF6: maximum gain exceeded
Digital gain value exceeds internal limit.
Increase analog coarse gain or increase illumination intensity. (see also section
White balancing error occurred. Error code No: 0x41: minimum gain exceeded
Digital gain value has reached lower limit.
Decrease analog coarse gain or reduce illumination intensity.
White balancing error occurred. Error code No: 0xF7: White balance cannot be
leveled
White balance process has exceeded time limit but up to now no error has occurred.
White balance may last very long if white reference area is large, line period is high.
Restart of white balance may finish the process successful.
For a special single camera color channel calibration (individual red/green and blue calibration),
see section 8.2.4.
