Patent number: 11887285Abstract: To enable a high quality HDR video communication, which can work by sending corresponding LDR images potentially via established LDR video communication technologies, which works well in practical situations, applicant has invented a HDR video decoder (600, 1100) arranged to calculate a HDR image (Im_RHDR) based on applying to a received 100 nit standard dynamic range image (Im_RLDR) a set of luminance transformation functions, the functions comprising at least a coarse luminance mapping (FC), which is applied by a dynamic range optimizer (603), and a mapping of the darkest value (0) of an intermediate luma (Y?HPS), being output of the dynamic range optimizer, to a received black offset value (Bk_off) by a range stretcher (604), the video decoder comprising a gain limiter (611, 1105) arranged to apply an alternate luminance transformation function to calculate a subset (502) of the darkest luminances of the HDR image, from corresponding darkest lumas (Y?_in) of the standard dynamic range image.Type: GrantFiled: January 30, 2023Date of Patent: January 30, 2024Assignee: Koninklijke Philips N.V.Inventors: Johannes Yzebrand Tichelaar, Johannes Gerardus Rijk Van Mourik, Jeroen Hubert Christoffel Jacobus Stessen, Roeland Focco Everhard Goris, Mark Jozef Willem Mertens, Patrick Luc Els Vandewalle, Rutger Nijland

Patent number: 9210414Abstract: A multi-view display system comprises a display controller (307) which controls a display (301) to display a sequence of multi-view images in repeating view frames. A shutter device (311), such as shutter glasses, comprises at least two shutter elements arranged to switch between an open shutter mode and a less transparent closed shutter mode. Each shutter element is associated with a view of the plurality of views. A shutter driver (309) controls the shutter elements in repeating shutter frames (413) having a shutter time slot for each of the shutter elements. The shutter elements are in the open shutter mode during an allocated shutter time slot and otherwise in the closed shutter mode. The shutter frame rate of the repeating shutter frames is higher than a view frame rate of the repeating view frames. The invention may reduce flicker while maintaining a low frame rate, e.g. for 3D displays.Type: GrantFiled: June 28, 2011Date of Patent: December 8, 2015Assignee: TP VISION HOLDING B.V.Inventor: Roeland Focco Everhard Goris

Patent number: 8482511Abstract: A liquid crystal (LC) display system includes an LC panel and a backlight unit. A controller controls the LC panel to display first and a second images forming a stereoscopic pair; controls the backlight unit to only illuminate the LC panel during a first time period after pixels of the LC panel have a stable optical state according to the first image, and during a second time period after the pixels have a stable optical state according to the second image; and generates a control signal for controlling a first shutter glass of a pair of 3D shutter glasses to be in a transmissive state for enabling viewing of the pixels of the LC panel only during the first time period, and a second shutter glass to be in a transmissive state for enabling viewing of the pixels of the LC panel only during the second time period.Type: GrantFiled: November 6, 2008Date of Patent: July 9, 2013Assignee: Koninklijke Philips Electronics N.F.Inventors: Roeland Focco Everhard Goris, Peter-Andre Redert
