Multi-Projection

The Fraunhofer Heinrich Hertz Institute has developed an immersive projection technique (panorama projection) for digital cinemas, which should convey a realistic (immersive) impression. With this technique you are able to project electronical movie pictures in a high size and resolution never seen before.

The typical large screen projection with overlapping of multiple single projections has been dramatically improved through absolutely field adjusted synchronization of any given number of sections as well as a transition- and stripe free overblending of the horizontal and vertical arranged projectors.
A modular concept and the MPEG-2 standardized compression algorithm, help to realize user specific formats and at the same time to reduce amount and expenses. Those features listed above were all implemented in the CineBox.

This principle (patent pending) will be sold through the supervision of a license.

Technical Background

Background to these activities is the still remaining insufficient resolution of digital projectors. Even a "State of the Art"-projector with its XQGA-resolution (2048x1536 pixels) is unsuitable for cinema usage on the one hand due to its resolution which is still on a low limit in comparison to a conventional projection apart from its immense investment expenses, on the other hand also due to the disadvantageous aspect ratio, e.g. of cinemascope films (2,35:1), which do not fit into the VESA standard of the digital projectors and only allow a usage of max 57% of the extremely expensive projector panels. Therefore the Fraunhofer Heinrich-Hertz-Institute proposes to combine two in comparison inexpensive standard SXGA projectors (1280x1024), so you can achieve 2406x1024 active pixel resolution. This resolution has not been accomplished with any commercial available digital projector worldwide.
