4 Warp Adjustment

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) pattern.

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.
