Color Cameras; Using An Auto Function - Basler acA2040-55 User Manual

Features AW00123409000
Camera.PatternRemovalAuto.SetValue(PatternRemovalAuto_Once);
After three image acquisitions the new correction values are generated and the camera
automatically sets Pattern Removal Auto to Off (PatternRemovalAuto_Off).

7.15.8.2 Color Cameras

In acA3800-14uc and acA4600-10uc color cameras, groups of four pixels each display the same
characteristic as their monochrome counterparts, that is, within a group, each pixel tends to show
a different response to light. The resulting artifact effect produces slight color shifts. These can be
corrected by using the white balance feature.
As with monochrome cameras, the artifact effect varies with certain "imaging conditions", that are
defined by the optical system, the illumination, and several camera settings (see Section 7.15.8.1
on page 309). Accordingly, to correct for artifact color shifts, you must perform white balance
whenever at least one of the relevant imaging conditions changes. This means also that you may
have to perform white balance when you normally would not, for example after having changed the
lens focus.

7.15.9 Using an Auto Function

The following instructions apply to all auto functions except the Pattern Removal Auto Function.
Using the Pattern Removal Auto Function is described in Section 7.15.8 on page 309.
To use an auto function using Basler pylon:
1. Select an Auto Function ROI.
2. Assign the auto function you want to use to the selected Auto Function ROI.
3. Unassign the auto function you want to use from the other Auto Function ROI.
4. Set the position and size of the Auto Function ROI.
5. If necessary, set the lower and upper limits for the auto function's parameter value.
6. If necessary, set the target value.
7. If necessary, set the auto function profile to define priorities between auto functions.
8. Enable the auto function by setting it to "once" or "continuous".
For more information about the individual settings, see the previous sections that describe the
individual auto functions.
