| Title: |
Optical and Electrical Blending of Display Images |
| Abstract: |
A method and a device for soft edge blending of projected display images
(16a, 16b) is provided. The method combines optical and electrical soft
edge blending in an blending area (26) by using electrical blending in
one fraction (146a, 146b) of the blending area (26a, 26b) of two or more
overlapping images and using optical blending in another fraction (144a,
144b) of the blending area (26a, 26b). The method according to the
present invention overcomes problems with manufacturing, alignment and
adjustment of optical masks (148a, 148b) used in optical blending and the
difficulties with electrically blending black images. The blending method
can also be used in systems providing switching from soft edge blending
to hard edge matching.
