Chameleon GB-200

Is a powerful and intuitive image blending and warping processor that provides the ability to merge overlapping edges of two or more projected imagescreating a seamless single image.

A cost effective auto blend option enables a perfectly seamless 2 channel blend in minutes.

Each GB-200 is equipped with two channels and is positioned inline between the input source (PC) and the projector.

The GB-200 has the ability to pre-cut a single image to form a seamless picture of up to a 2x2 projection array, making your installation quicker andeasier. With the help of a multi output graphic card, more complex arrays are not a barrier for the GB-200.

Resolutions including 1080p and WUXGA are supported via VGA, DVI and HDMI connections. Colour, black level and gamma correction are included to take onthe challenges faced when blending multiple projectors.

Image Stacking

Double your image brightness without significantly increasing your installation cost; with warp adjustment, you can achieve anybrightness you want.

Image stacking permits flexible installations and greater redundancy; an image can be displayed without interruption while swappinglamps. Alternatively, images can be realigned to be perfectly square if aligned beyond the lens shift range.

Advanced grid point adjustment for flat and curved surfaces

.The software tool allows up to 17 x 17 grid points of adjustment
.Each point can be individually adjusted with sub-pixel precision.
.Curved screens and complex surfaces are effortlessly covered.

Black Level Uplift

Advanced black level uplift with RGB and HSL correction allows you to accurately match both the outside and overlapped areas in orderto achieve a perfect seamless image when the lighting environment is very low.


Multi-Region Colour Correction

Advanced multi region colour correction allows you to adjust the white points of two projected images to make a seamless image.
