Soft edge blending is a method, used to create a larger video display by combining the image of two or more projectors. When overlapping projectors, the overlapped region has higher brightness then the non overlapped regions, so there is a need to feather the edges. The process of edge blending, involves manipulation of individual pixels to ensure perfect intensity over a specified blend zone.
Each projector being used, will output a portion of the desired image, overlap with the outputs from the other projectors. Using the edge blending process, the result is a perfect seamless display, created out of multiple images aligned horizontally to create unusual displays.
Logix-4D edge blending is a very cost-effective and efficient method of producing the most innovative and extraordinary large displays.
With edge blending capability, along with the multi-channel frame, accurate playback synchronization, all offered by Logix-4D, you can playback a large mega-pixel video split into multiple high definition files. Any number of projectors can be blended to create a large seamless image.
Every overlapped region is provided with Intensity correction and control over brightness of each color, this allows easy compensation for many of the problems faced when blending projectors.
