Edge blending is a technique used to describe the process of visually combining several projected images to make a single seamless image. 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. In both cases, a number of projectors are needed which are firstly overlapped and then visually joined together using an edge blending technique.

There are two types of edge blending, one software based and one hardware based. Software based solutions can be loaded into the main PC driving the projectors and generally offers the user with a player that they can use to show images, documents and videos etc on their large blended projection display. The hardware solution is a box that sits between the source equipment and projectors and processes and blends the images together allowing any source and even a windows desktop to be blended.

The C2-2450A enables easy Edge Blending using 2 or more units. DVI and RGB inputs and outputs at virtually any resolution and refresh rate are supported. All settings are stored in non-volatile memory and are retained even when power is switched off. Ten user defined presets are also available to customize settings for various applications. All the functions can be controlled via the front panel Push Buttons, Infrared, RS-232 or IP. Windows Control Panel software is provided and most third party control systems interface directly with the entire C2 range of products. A front panel LCD makes setup easy. The unit is housed in a desktop case and an optional rackmount kit holds one or two units.
