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: 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: 9766535Abstract: 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 narrow wavelength bands. Each screen is configured to strongly diffusely reflect light in narrow wavelength bands that are different from the wavelength bands reflected by other screens in the immersive display system. Projector systems can be configured to provide light to associated screens in the narrow wavelength bands reflected by those screens.Type: GrantFiled: July 21, 2015Date of Patent: September 19, 2017Assignee: Barco, Inc.Inventors: Patrick Candry, Bart Maximus, Scott Stremple

Patent number: 9726968Abstract: 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 one screen having an array of micro-lenses, a light polarization layer on top of the array of micro-lenses, a polarization rotation layer, a light reflection layer, and a section of non-polarizing light scattering material for individual micro-lenses in the array of micro-lenses. In use, light from a projector associated with the screen is substantially scattered by the non-polarizing light scattering material and light from a projector associated with a different screen in the immersive display system is substantially absorbed by the polarization layer.Type: GrantFiled: October 27, 2015Date of Patent: August 8, 2017Assignee: Barco, Inc.Inventors: Patrick Candry, Bart Maximus, Dirk Maes

Patent number: 7812300Abstract: An imaging system (100) for displaying color images is described. The imaging system (100) comprises an illumination source (102) for generating an illumination beam, an illumination splitting means (106) typically for generating different primary color illumination beams and a plurality of image modulators (104a, 104b, 104c). The illumination splitting means (106) comprises a dynamic selecting means (108) adapted for, for a single color image to be imaged, subsequently generating different sub-sets of primary color sub-beams from said illumination beam and directing these sub-sets of primary color sub-beams to a static selecting means (110).Type: GrantFiled: December 27, 2007Date of Patent: October 12, 2010Assignee: Barco N.V.Inventors: Patrick Candry, Koen Malfait

Patent number: 7432667Abstract: An electronic lamp control system for life time extension of a DC high intensity discharge lamp has a light sensor (130) for sensing an output of a lamp (31), a power supply (110) for the lamp (31), and a controller (20) for controlling the power supply (110). The controller (20) has a high pass filter (20c) for compensating for a leading edge of a detected change in lamp power output caused by each arc displacement. Lamp life is extended since damage to the lamp electrodes by the arc displacements is reduced. The system can have multiple lamps for the same illumination area, or multiple channels for illuminating different areas, coupled to provide uniform illumination. The controller (20) can compare a sensed level to a reference, to output a level control signal, then add a correction signal from the high pass filter to the level control signal.Type: GrantFiled: May 23, 2006Date of Patent: October 7, 2008Assignee: Barco N.V.Inventors: Kurt Callewaert, Patrick Candry, Paul Verledens

Patent number: 6224215Abstract: The present invention relates to a light valve image projector with a disposition for improving the contrast of an optical image projected on a screen by that projector. The projector comprises at least one illumination system, at least one field lens, at least one set consisting of a polarizer, an LCD and an analyzer and at least a projection lens, and presents at least one optical axis which includes an angle &agr; with the optical axis of the projection lenses. The invention consists in positioning the analyzer so that it includes an angle larger than &agr; with the LCD, at least for the light rays that pass through the contrast limited area of the LCD. The invention consists furthermore in placing the polarizer so that it includes an angle larger than &agr; with the LCD. Both the analyzer and/or the polarizer may have a flat or a curved surface.Type: GrantFiled: November 12, 1999Date of Patent: May 1, 2001Assignee: Barco N.V.Inventors: Bart Maximus, Patrick Candry, Bart Van Den Bossche

Patent number: 5801780Abstract: A method and a device for converting a first picture composed of M pixels towards a second substantially identical picture composed of L pixels (M.epsilon.N, L.epsilon.N, M.noteq.L) which are destined for pixelwise representation, wherein each K.sup.th first pixel value is weighed with a weight factor h(k,i) determined by means of projection of the second picture on the first picture and wherein before the second pixel value y(i) is determined a first transfer function component (T) is added to each k.sup.th first pixel value and after determining the second pixel value y(i) a second transfer component (T') is added to that pixel value.Type: GrantFiled: February 8, 1996Date of Patent: September 1, 1998Assignee: BarcoInventors: Jan Schaumont, Patrick Candry
