Firstly, different projectors have different characteristics, even if you are using the same brand and model. In principle it sounds easy, but in practice it is very hard to do. Unfortunately, achieving a seamless image using this technique is near impossible. To try and accomplish this, the projectors are carefully arranged so that the right-hand edge of the left-hand projector sits perfectly next to the left-hand edge of the right-hand projector. This method is technically referred to as image butting because the projected images are butted up next to one another. Figure 1: A wide image that we want to project using three projectors.Īt first glance it might appear that the easiest way to produce this image across three projectors would be to line up the projectors next to each other. In both cases, a number of projectors are needed which are firstly overlapped and then visually joined together using an edge blending technique.

Typically, this is done to increase the size of a projected image to make a very wide image, or by combining a number of lower resolution devices together to increase the total resolution of a display. If ET-CUK10 is activated together with the Geometry Manager Pro software (ET-UK201), you can enjoy the maximum performance of Panasonic projectors.Edge blending is a technique used to describe the process of visually combining several projected images to make a single seamless image. The Auto Screen Adjustment Upgrade Kit works as an upgraded function of Geometry Manager Pro software. It’s a fantastic piece of kit that’s simple yet highly effective.”

There is less degradation on the image compared with other external software based systems, since the calibration adjustment is processed by the projector’s internal image processor. Hartmut Kulessa, Marketing Manager at Panasonic, said, “The auto screen adjustment upgrade is compatible for a range of different screens – such as convex, portrait, concave and S-shaped. This system combines camera technology and Geometry Manager Pro software, with just a few easy steps for set-up. The ET-CUK10 shortens adjustment duration time for multi or curved screen projections and makes seamless imagery that’s edge blended, colour-matched and geometrically adjusted. The Auto Screen Adjustment upgrade kit, available for Panasonic Professional models including the PT-DZ21K, DZ13K series and DZ870 DLP™ projectors, dramatically reduces installation time and cost. ISE 2014 saw the introduction of Panasonic’s ET-CUK10 software which allows automatic edge blending, colour matching and geometric adjustment for high-end DLPTM projectors.
