QXGA Digital Mapping, Blending and Shading with Digital Video I/O

Building upon the world leading ProMap TM system for Digital Projection onto Curved Screen Displays, Equipe announce ProMap TM Quattro. As with all ProMap TM systems, Quattro provides continuous digital transmission between image source and projector with zero delay and zero degradation of the image. Utilising a completely new design, Quattro also provides Native WQXGA at 60Hz Advanced Bicubic image filtering for enhanced image quality Digital (DVI) Video Input Digital (DVI) and Analog Video Output Auto format detection / selection Up to 4 channels per unit, easily extendable to 32 channels Rapid Setup using comprehensive ProMap Composer for Windows Active Stereo support at 120Hz up to SXGA+

Why Use ProMap TM ? ProMap TM is designed for use with digital projectors such as the Equipe Contour 100 TM, Contour 300 TM and Contour 650 TM visualisation projectors for curved and complex shapes of screen. Such digital projectors provide sharp and bright images at very low cost but do not have the capacity to electronically bend the picture as it is drawn to match a curved surface screen. It is therefore necessary to "map" the position of each picture element (pixel) to a different position on the internal projector image such that an observer of a curved screen sees an undistorted image. This has to be done without loss of picture quality that could be caused by splitting the image into pixels, whilst avoiding adding any delay in updating the scene that requires instantaneous visual cueing to control movements.

Equipe ProMap TM applies advanced digital filtering techniques to eliminate aliasing effects that can be caused by mapping pixels to a new position. Where two images overlap, a blend region is defined where one projector fades out as another fades in. Using digital techniques this blend region is almost imperceptible to the observer as the correct proportion from each projector is precisely calculated. ProMap TM Composer, a powerful GUI, allows complete control of mapping, blending and hot-spot compensation using a WYSIWYG editing environment.
	Unlike CRT blending, ProMap TM alignment rarely needs adjusting after initial set-up. Independent digital shading of each colour plane provides the means to compensate for colour shifts between projectors and colour variations within each projector field. Compensation for shading variations within curved dome displays and back projection hotspots can also be pre-calculated and removed by loading into the ProMap TM shading system
Mapping is defined by a B-Spline mesh pre-calculated to match the optical geometry. It may then be finely adjusted for precise alignment to the observer's eye position. A portable laptop control handset is used to make all adjustments. Up to four ProMap TM channels are contained within a PC that can be expanded, by adding more PCs using a standard network, to an unlimited number of channels.
