Edge Blending
Christie Edge Blending is an innovative set of software functions that can quickly and
easily blend whitelevels along the edges of multiple adjacent projected images to
create a single seamless larger image.
What is a Blend?
In simple terms, a blend appears as a gradient strip
along an edge of a projected image. It is darkest along
the extreme edge of the image, and lightens nearer to
the rest of the image (see right).
How Are Blends Used?
In multiple-projector walls, complementary blends
between neighboring images can compensate for the
extra "brightness" or intensity where these edges overlap. By controlling blend width
and other properties, you can achieve uniformity across the group of images. Visible
overlaps will disappear:
For best results, use the same projector model and type throughout your display wall.
In addition, avoid high-gain screens whenever possible—the optical performance of
such screens demands minimal image offset, thus projectors must be located very
close to one another.
