Other Functions; Edge Blending Procedure - Christie roadie 25k User Manual

Blend Shape
determines the rate
of roll-off across the blend width,
i.e. how quickly the white levels
across the blend change from
light and dark. Increasing the
Blend Shape setting accelerates
the rate of change at both
extremes so that less of the region
appears mid-gray (see Figure 2).
Decreasing the Blend Shape
setting slows the rate of change
so that more of the region appears
mid-gray. For most applications, this subtle control is best left close to 50.
Blend Midpoint
determines the white
level at the blend midpoint (the
point equidistant between the
beginning and end of the blend).
Increasing the Blend Midpoint
setting creates a blend that appears
brighter than the rest of the image.
Decreasing the Blend Midpoint
setting creates a blend that is darker
than the rest of the image. A setting
of 50 means the midpoint is
approximately 50% black—for best results in most applications, keep fairly
close to this default.

Other Functions

For convenience, the Edge Blending submenu also includes related options for
enabling a specific color and/or test pattern, or for working with colors or the lamp.
Such functions duplicate those provided elsewhere in the menu system.

Edge Blending Procedure

NOTE: Before attempting to work with edge blending software functions, you must 1)
physically align the projectors/images by correctly overlapping the displays from
your intended external source, and 2) Match colors and Brightness Uniformity.
For a shared edge, all Blend procedures and settings
should be identical on BOTH projectors.
1. Start with 2 projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in
the top checkbox.

3.

Go to "More" and set everything in the Edge Blending (2) menu to 50.
