What is image blending?
The use of super-wide panoramic screens is the norm for large scale events in Australia.
To project onto these panoramic screens we use a special technique known as “image blending”. This involves the use of two or more projectors, each portraying a section of an image, blended or overlapped seamlessly together to create a single, wider image on screen in an abnormal aspect ratio.
When done correctly, it is almost impossible for the guests in the room to notice with the naked eye where the image has been blended.
In terms of panoramic or “Megascreens” at AVPartners at Perth Convention and Exhibition Centre we own 2 custom made 16M x 3.4M Megascreens but we also project onto our large 22M x 9M cycloramas which allows us to do full floor-to-ceiling blended projection!
Most high powered projectors these days also have internal software to aid in the blending process. The “corner correction” function allows our technicians to drag any corner of the projectors up, down, left or right which makes the process far more efficient than attempting the blend with conventional keystone.
At AVPartners, we like to use the SpyderX20 with full HD projectors for our blending. The SpyderX20 is the world’s most powerful video processor and presentation switcher, combining a versatile hardware-based video processor with the flexibility of a multiple video source matrix switcher.
