[Shift] has two functions: one is to shift [Edge Blend] location and another function is to do
[Edge Mask] in not [Edge Blend] borders.
When user selects the edge with [Edge Blend], user can apply “+” value (0 to +500) to shift the
whole [Edge Blend] position. If the value is “-“ (0 to -100), user can see color uplift in [Edge
Blend] area. The purpose is for user to do color fine tune in edge blending area.
When user selects the edge without [Edge Blend], [Shift] will change image border location with
black background without changing image position. It implements [Edge Mask] function follow
the final result after geometry alignment without changing aspect ratio. It can execute curved
edge mask up to maximum 500 pixels after geometry alignment.
[Shift] is to shift [Edge Blend] location in
[Edge Blend] edge. If the value is set to “-
“, it will uplift the color in edge blending
area.
It can execute [Edge Mask] on the edges
in non-overlapped region.
Different projectors may have different gamma curve. Different “Display mode” in the same
projector will also have different gamma curves. These gamma curves will affect projector color
and the final color in edge blending area. The common issue is gray or color banding effect.
These issues are more significant in pure color or white back ground display.
[Gamma] function is to adjust the gamma curve in edge blending area for each projector
through independent RGB gamma curve adjustment. It will improve video quality in overlap
region.
User needs to select right display mode (gamma curve 2.2 is the best gamma value in the
projector setting) and fine tune the color difference among the projectors to minimize the
possible banding effect in edge blending region.
[Gamma] function is not functional when [Edge] setting is not executed.
