Edge Feathering

The overlapping image data in the blend region must be edge-feathered to support a seamless optical blend. The transfer function must be programmable to support blend regions of different widths and adjust to different video characteristics. A typical blend function is illustrated below.

Accurate projector setup is essential for creating seamless images. Please note the following important guidelines:

The projectors must be precisely aligned to overlap the adjacent blending regions.

The brightness, contrast and color balance of the projectors must be adjusted to provide a uniform appearance across the entire screen.

Custom test patterns and an alignment procedure are used to simplify this process and provide an optimal result.

Mixing and matching projectors is not recommended as it makes the adjustment process much more difficult.
