Adjusting the black level of projectors in overlap regions can present a challenge especially in the non addressed edge pixels. This is why we introduced a new beta feature for advanced black level correction in our VR&SIM and Integrate Plus releases.

Follow the steps below to use the feature:

1. Perform a camera calibration of your projectors.

2. After the scan, convert the calibrated compound(s) to “projector space overlap” : Calibration > Conversion Tasks

3. Next, from the main window click on “Adjust Projectors” then choose the first display to correct and click on the “Blacklevel” button below

4. Black level Adjustment :

i. Select a mask “C0” , “C1” .. etc

ii. Adjust the points on the masks if needed until the zone is completely covered

iii. Adjust the contour size with the Increase/Decrease buttons

iv. Adjust the gain slider until you are satisfied with the result

v. Optionally, click on “Overlap Gain” to adjust separate RGB channels

vi. Finally, click on ” Okay” and repeat these steps for the other displays until you are satisfied with the overall result.

vii. To apply the black level adjustments: from the main window, open the “Color & Blending” options and turn up the blacklevel slider to the same value “Adjust Gain” in (iv)
