Edge [Blend] settings
➢
[Blend] menu is to merge the images from multiple projectors to become one seamless image.
➢
The scaling factor between two adjacent projectors shall be the same. It means the image size
under the same resolution should be the same.
➢
Geometry alignment is required before edge blending:
✓
To let the image has the same grid size (same scaling factor in both horizontal and vertical
directions)
✓
To let images from two adjacent projectors stack together in horizontal lines and vertical lines.
➢
Sub-menu under [Edge Blend] menu
✓
[Edge]: select the right edge and set overlap pixels. The pixel no. is same as the overlap grid
size multiple grid number. If overlap is 10 grids, the overlap pixel is 320 in default grid size.
✓
[Shift]: shift image edge blending location and implement [Edge Mask] function for non-
overlapped edges with black background.
✓
[Gamma]: adjust gamma value in [Transition] and [Gain] in each channel to improve banding
effect in overlap region.
✓
[Offset]: execute black level uplift in non-overlapped area to compensate light leakage in
projectors.
✓
[Corner]: Execute precise [Offset] location alignment.
✓
[Color]: Execute White Balance correction for individual projector.
✓
[Mask]: Mask out unnecessary image in the image edge.
✓
[Grid]: set grid pattern size for Horizontal and Vertical directions.
