12.0 EDGE-BLENDING SETUP 12.1 Introduction Edge-blending is a method whereby two or more video/data projectors are used together with part of their images overlapping, thereby creating a wider (or taller) display more suitable for showing wide-screen video images. The term edge-blending relates to the fact that the overlap needs to be carefully handled to prevent the overlap causing image brightness problems. This guide is intended to summarise how to setup such projectors when used with a suitable number of TV One’s CORIO®2 scaling engines. The C2-7000 series are dual processors and therefore require only a single unit to perform both tasks, whereas other units will generally require two units to be used together, with a distribution amplifier on the input so that both units receive an identical video source. Image 1 Image 2 Basic method of overlapping two projection images to create a larger one. Because the two overlapping areas will create a brighter than normal image, ‘blending’ is performed on the edges to allow seamless merging of the images together. The ‘blend’ is basically an S-shaped curve that is applied to gradually reduce the brightness of the image at the edge, so that they can overlap properly:
S-curves for left and right projectors, with edges blended. S-curves, when properly overlapping, will add together to result in full brightness. 12.2 Edge-blending requirements To obtain the best edge-blending results, you will need: 1. A perfectly flat projection screen. This is vital, or it will not be possible to perfectly align your two projected images with each other. 2. Two matched projectors. Every projector on the market is different, with different lenses, projection methods, brightness, contrast, etc. Ideally you will need to identical projectors to obtain the best results. 3. A solid table or mounting bracket. Once you’ve set up your projectors and aligned them, you will not want them to move – so some method of holding them in place with brackets secured to walls or ceilings, or simply a sturdy table, will be vital. 4. Adjustable mountings (or more preferably projectors with built-in advanced adjustments). Proper alignment of two projectors can be very difficult, but will be aided by using some sort of mounting bracket that is easily adjustable. You may need to be able to move the projectors independently in all directions: left, right, up, down, forward, backward and also be able to tilt them to correct for any rotational errors. 5. Adjustable projectors. Most projectors will offer certain advanced features such as key-stone correction. This will be vital to ensure proper alignment, as it will partly compensate for mounting problems. 6. Of course, you’ll need one or more CORIO®2 units (depending on the model) with the latest firmware that supports edge-blending.
