  • Optical and electrical blending of display images
    Patent number: 7339625
    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.
