VP-790 Blending Images - Setting the 4-Corner Warp

Setting the 4-Corner Warp
The images from both processors/projectors must be geometrically corrected to fit
the screen and the overlapped regions must be set to align accurately. This is
achieved by warping (changing the shape) the image.
1. Change the test pattern to the Warp Adjust (F).
The left hand pattern is green and the right hand pattern is magenta
intentionally.
The color is set automatically when the position information is entered. The
alternating colors help in two ways:
•
To clearly see each projection separately
•
When the geometry adjustment is complete, the parts of the pattern in the
overlapping blend region will be super-imposed and appear white
Inaccurate adjustment can be clearly seen as a colored fringe around the white.
