Chameleon GB-200 image blending and warping processor Is a powerful and intuitive image blending and warping processor that provides the ability to merge overlapping edges of two or more projected images creating 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 2×2 projection array, making your installation quicker and easier. 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. Color, black level and gamma correction are included to take on the challenges faced when blending multiple projectors.

Image Stacking

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

Image stacking permits flexible installations and greater redundancy; an image can be displayed without interruption while swapping lamps. 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

1.The software tool allows up to 17 x 17 grid points of adjustment

2.Each point can be individually adjusted with sub-pixel precision.

3.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 order to achieve a perfect seamless image when the lighting environment is very low.

Multi-Region Color Correction

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

GB-200 + Optoma Auto Blending Tool

Auto blending is a simple and easy solution for reducing the time required for an edge blend installation. Using a camera to capture the two projected images, the Optoma auto blending tool automatically calibrates and adjusts the GB-200 settings to perform a blend in less than 7 minutes
