How To Overlap the Projection Images
How to Overlap the Projection Images on a Screen
You can obtain a seamless image by using the Edge Blending function which blends the images projected from multiple projectors and digitally dims the edges of the images and the Color Matching function which eliminates color unevenness. Follow the steps from 1 to 5 (or 8 if necessary) below to adjust multiple projector images.
Edge blending
1 | Configure the settings for screen size, image level, and lamp mode. These settings must match those for the rest |
of the projectors. Select Constant mode from the Lamp mode menu and then specify the same Target value as the | |
2 | projectors. |
