Optoma has launched a simple and fast solution to an otherwise complicated and labour intensive procedure with the new Chameleon GB-200 processor. The GB-200, announced at ISE earlier this year is the first product in the forthcoming Chameleon signal processing range. The Chameleon products are designed to support Optoma’s ProScene projector range to provide greater control and flexibility for ambitious projects.
As the name suggests, the Chameleon GB-200 allows you to merge the overlapped edges of two or more projectors to create one seamless image. The product is also equipped with two channels, so a single processor can serve two projectors.
The impressive eight metre wide edge blended arch Optoma showcased at ISE was created using four ProScene EH7700 projectors and two Chameleon GB-200 processors. Each projector generated a Full HD image, which were blended together to create a seamless image at 8k resolution across the 4.5 metre high, giant curved arch.
Justin Halls, Head of Product Management at Optoma commented, “The GB-200 provides greater bandwidth and flexibility for complex and impressive installations. It is simpler to set up than alternative solutions and the overall cost of installation is lower. This is due to both time saving in installation and the fact the Chameleon GB-200 is dual channel, therefore reducing the amount of equipment needed.”
The Chameleon GB-200 includes both black level uplift and multi-region colour correction, which makes matching multiple projectors quicker and easier than ever before. In addition, it allows sub-pixel control of the alignment of both images with up to 289 individual points of adjustment on each projector enabling use on both flat and curved surfaces.
Also at ISE, Optoma demonstrated the power of the GB-200 to create a 180 curved screen where two EH503 projectors were set up to project a high-action video game. The panoramic screen created a much wider field of view than a typical rectangular screen giving a more immersive gaming experience.
The Chameleon GB-200 harnesses the power of the PC’s graphics card to generate a single high resolution output (approx. 3,600 x 1080 pixels). This is fed to both channels of the processor via a HDMI splitter. The correct part of screen is sent to each projector and the GB-200 processor blends and warps the content to form one impressive and bright high resolution image.
The GB-200 processor can also be used for stacking, when a project needs higher lumens. Stacking overlays images from multiple projectors to produce a higher brightness.
Justin commented: “A single projector of equivalent brightness is generally more expensive and bulkier. Stacking enhances portability with smaller, lighter units easier to transport and install. It improves reliability (if one unit fails, the second unit will still be operational) and it allows scalability with the option to add more projectors if higher brightness is required.”
The Chameleon GB-200 can also be automated using a camera and the Optoma auto-blending tool. A trial version of the software is included with the processor. This potentially reduces the set up time from hours to just a few minutes. The auto-blending software guides installers through a simple step-by-step process. Once connected, the camera self-calibrates, and the desired screen area is then set using simple corner adjustment. The camera feeds back the location of the dots to the processor and the blend is then enabled.
All Optoma signal processors can be controlled via a network enabling complete control of the project at all times.
