Multi Image Processor

High end blend and warp image processing engine

About Multi Image Processor

The Multi Image Processor WB2560 and WB1920 are high end warp and blend processing engines with a whole range of features for simulation, entertainment, scientific visualisation, and medical imaging markets. Now including Camera based AutoAlign compatibility with popular solutions and RealTime Warp, added to the low-latency, ultra high quality blend and warp, patented Black Level Matching, and Sub-Pixel Level Matching for colour correction - every pixel is the same colour and brightness for absolutely uniform images. And, not to forget, active 3D stereo compatibility up to 1920x1200@120Hz. System configuration just got a whole lot easier and future proof.

Key features

  • Camera based AutoAlign compatibility for popular solutions from DomeProjection, Scalable Display Technologies and Mersive
  • 2560x1600 and 1920x1200 pixel resolution versions
  • Full geometry correction and blending
  • Patented per-pixel Black Level Matching
  • Unique Sub-Pixel Colour and Uniformity correction
  • Unlimited Scalability
  • 3D stereo compatible
  • Rack Mountable; 2 channels per 1U

Camera based AutoAlign compatbility

Both the WB2560 and WB1920 processors enable fully automated camera based AutoAlign features1 empowering users and integrators to fully align, colour match and calibrate any number of channels in domes or with spherical screens, and with flat or curved surfaces in a matter of minutes, system solutions are easier to set up and maintain right out of the box. What's more, even with older, and already installed systems, everything is upgradable by just upgrading firmware and the version of ProNet in use.
1) To take advantage of these features, WB-series processors must be combined with third party solutions from Scalable Display Technologies, Domeprojection, or Mersive.

Fully WQXGA (2560x1600) compatible

The Multi Image Processor WB2560 features 6.25 Mps image processing for full 2560x1600 image processing without any limitations. Featuring Dual Link DVI in/out, it easily blends, warps, and colour manages any resolution up to WQXGA, making it forward compatible with next generation displays and interfacing. The WB1920 shares all the same features, but with a lower 1920x1200 maximum image resolution. The high bandwidth enables high frame rates for reduced smear and image artefacts.

RealTime Warp functionality

White setting up and calibrating, it is important that changes to the system configuration can be viewed and inspected in real time. Enter RealTime Warp. Everything you do to the setup, including geometry changes, filtering, and overlap, blend zones and more is instantly displayed back for visual inspection and acknowledgement.

Black Level Matching – BLM

For truly seamless blending and matching between multiple displays, the Multi Image Processor system features patented (US Pat No. 6,760,075 B2) Black Level Matching functionality. Black level of individual displays can be adjusted on pixel level, so that the result is a completely uniform display at all levels.

Pixel Level Matching™ – 3-channel-pixel level gain and lift correction

Additional to BLM, the Multi Image Processor features individual RGB gain and lift per pixel; Pixel Level Matching™ - PLM™. This ensures completely uniform images in both colour and brightness levels. A challenge in displays and ordinary processing systems, the PLM functionality integrates seamlessly with the display, and can be monitored and corrected directly from the ProNet™ control and setup application.

4x4 Lanczos or bicubic interpolation adaptive filtering

The high speed dual-core processor in the Multi Image Processor enables very sophisticated filtering and scaling filters. Several types of filtering can be selected and applied, Applying the acclaimed 4x4 Lanczos filtering method in a random pattern to blend and correction zones retains a very high degree of detail and sharpness also when the image is electronically corrected.

Unlimited scalability

There are no scalability limitations when using the Multi Image Processor system. Any number of channels can be combined to a single image, without constraints.

Zero latency

Blending several Image Generators and projectors together for a single, multiple channel image is done with absolute zero latency. Applications that require geometry correction feature the least possible latency, typically less than one frame, even in the worst case installations. Latency is dependent only on rotation correction.

3D stereographic displays

The WB2560 supports up to 1920x1200 at a full 120Hz refresh rate active 3D stereo, with full warp and blend capabilities. This makes it easy to assemble a fully immersive system of corrected 3D displays.

Rack mount hardware

Each Multi Image Processor is half-width, 1U standard size, so two channels can be combined in a single standard 19" 1RU rack mounting plate. Each Multi Image Processor also features its own internal power supply, so power management is easy, as there is no wall-wart or external power supply module. The double processing 1RU unit easily creates a simple two-channel blend, or single image 3D stereoscopic geometry corrected setup for use on any surface.

Disclaimer: Please note that for blending and overlap between channels - the blend and overlap zone and overlap pixels must be set at and supported by the Image Generator via a compatible graphics card, such as for instance those featuring Nvidia's Mosaic technology.
