Patent number: 9986214Abstract: An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light for controlled periods of time. Adjacent screens can be configured to selectively reflect light during different periods of time. The projector systems can be configured to project video onto their respective screens while the associated screen is configured to selectively reflect light rather than absorb light.Type: GrantFiled: July 21, 2015Date of Patent: May 29, 2018Assignee: Barco, Inc.Inventors: Patrick Candry, Bart Maximus, Geert Matthys, Claude Tydtgat

Patent number: 9785045Abstract: Seamless display screens that are portable and can be installed in a fast manner, as well as a projection unit for use with several projectors as well as methods of making such display screens. The projection unit can be suitable for being used as a rear projection unit. Devices are provided for reducing depth of the projection unit, to compensate for blend zones and to make it easy to transport such as to be suitable for trade shows, e.g. mirrors or Fresnel lenses.Type: GrantFiled: September 7, 2014Date of Patent: October 10, 2017Assignees: BARCO NV, BARCO CONTROL ROOMS GMBHInventors: Stefaan Ducasteele, Tom Dewaele, Davy Van Colen, Lutz Nehrhoff Von Holderberg, Geert Matthys

Patent number: 9772549Abstract: An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in a tailored polarization state. Adjacent screens can be configured to selectively reflect light in orthogonal polarization states. The projector systems can be configured to project video onto their respective screens with light in a suitable polarization state. The screens can be further configured to selectively reflect light within a plurality of tailored spectral bands, the spectral bands being different for respective screens.Type: GrantFiled: July 21, 2015Date of Patent: September 26, 2017Assignee: Barco, Inc.Inventors: Patrick Candry, Bart Maximus, Geert Matthys, Claude Tydtgat

Patent number: 7339625Abstract: A method and a device for soft edge blending of projected display images (16a, 16b) is provided. The method combines optical and electrical soft edge blending in an blending area (26) by using electrical blending in one fraction (146a, 146b) of the blending area (26a, 26b) of two or more overlapping images and using optical blending in another fraction (144a, 144b) of the blending area (26a, 26b). The method according to the present invention overcomes problems with manufacturing, alignment and adjustment of optical masks (148a, 148b) used in optical blending and the difficulties with electrically blending black images. The blending method can also be used in systems providing switching from soft edge blending to hard edge matching.Type: GrantFiled: June 28, 2004Date of Patent: March 4, 2008Assignee: Barco N.V.Inventors: Geert Matthys, Bart Maximus, Glenn Devos

Patent number: 7278746Abstract: A blending tool is described for blending sub-images of a multi-channel projection system comprising a plurality of projectors. The blending device typically has a number of adjustable optical blending means which each are adapted to be mounted on a projector of said multi-channel projection system. Using a removable controlling means allows automated controlling of at least one of the adjustable optical blending means, or a blending component thereof. The removable controlling means therefore has engaging means for temporary engaging the removable controlling means to the adjustable blending means. In a preferred version, the blending tool allows remote control of the adjustable blending means such that blending can be performed from the viewing side of the projection system, even for rear-projection systems. Furthermore a method for blending and projection systems adapted for being blended using the blending tool are provided.Type: GrantFiled: April 8, 2005Date of Patent: October 9, 2007Assignee: Barco N.V.Inventors: Geert Matthys, Ludo Francois Victor Bruwier

Patent number: 7090361Abstract: The present invention relates to projection systems, more particularly to a method for visualising test pattern grids in such a projection system. An array of adjustable, directed light sources is described, which is to be used as a test pattern generator for alignment of at least one projector. Each light source is fixed onto a surface from which it is movable with two degrees of freedom, preferably by putting the surface in plastic deformation. This can preferably be done with help of few tooling aids, and by using one hand only.Type: GrantFiled: September 12, 2003Date of Patent: August 15, 2006Assignee: Barco N.V.Inventors: Geert Matthys, Johan Decock
