Edge blending, that is, the two images into a region of overlap, which overlaps the region of the signal, according to a linear relationship between the fusion fade, makes a direct overlap between the “light zone” effects as much as possible to eliminate in order to achieve real seamless effect. G802 is dual channel processor with the ability for warp, geometry alignment, image stacking, edge blending and edge mask.etc. It can control up to two projectors. Four inputs, two outputs and one loop out port are designed in G802. User can display one big edge blended image or two independent displays in one system. GeoBox - M801 - Edge blending processor M800 is curved screen edge blending processor with the ability to provide multiple processing modules to control from 1 to 4 projectors based on user’s requirements. User can combine the images on the ceiling, wall and floor to create immersive display through GeoBox edge blending technology. It is world unique technology to setup all kinds of edge blending and immersive system through remote controller without PC. There are two edge blending product lines. One is G800 and another one is M800.

---Mviewer make it easy and cost-effective

Stunningly large projections, a myriad of images in a unique format, and extended panoramas that tear open your poorly limited visual expectation of space – all this can be achieved by joining individual HD video units into a whole. Mviewer multi-channel blending hardware makes a bright and seamless entire view with smooth brightness transition between overlapping images.

Edge Blending Processor Software

There are a lot of applications that benefits from high resolution and ultra wide displays, for example, immersive virtual reality and scientific visualization. But most projectors with high luminance are currently limited to the resolutions of XGA (1024x768) or WXGA (1280x800). Although you can choose some high resolution projector, the brightness still remains a problem. There are projectors with satisfactory brightness and resolution, but they cost a lot—maybe tens of thousands of dollars.

One possible solution is to combine a number of commodity projectors. Each projector makes a unit of the whole screen to form a large seamless SHR vision, for which edge-blending technology may be the only choice. Edge-blending is a method whereby two or more projectors are used together, with edges of projected images precisely overlapped and technically blended to create a seamless presentation on a wide screen. The term 'edge blending' means that the overlapped edges need to be carefully processed to blend together without appearing any brighter than other regions or at least until the brightness difference is less easily noticed by viewers.
