Dual Projection and Edge Blending
During our recent project at British Airways, we were faced with the challenge of displaying a very large image over a 5.8m x 3.2m screen without losing brightness through the projection. The solution involved using two Panasonic projectors synchronously to increase the lumens to a total of 34,000, which is the equivalent of LCD brightness.
Using a large mirror hung from the ceiling, Paragon Multimedia were able to reflect the image onto the large screen with high quality, however there was the issue of aligning the two projected images. Although there are many image processors on the market, we opted for the Calibre HQView 320, thanks to its simple interface and precise control.
Using software that’s downloadable from Calibre’s website, the user is able to stretch, warp and edge blend the image until it matches its partner projector. The software allows you to move or adjust the images to as small as 0.2 of a pixel, creating the ultimate precision for edge blending.
This compact scaler can be use directly using buttons on the device, however the more detailed adjustments require the software, which is very easy to use and allows the user to view the changes they’re making as it happens on the screen. With the HQView being customizable, this kind of edge blending has been used on an array of different project including video walls at tourist attractions, to help align different panels, or for an image that needs to be warped around an uneven surface, such as the curved IMAX cinema layout.
With a 3D possibility and several component inputs including HDMI , DVI and VGA, this type of equipment is key to clear and crisp images on a large scale.
