20130242389 | Method and System for Shaped Glasses and Viewing 3D Images - Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images. | 09-19-2013 |

20140022637 | System for 3D Image Projections and Viewing - Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D images. | 01-23-2014 |
20140043352 | High Luminance Projection Displays And Associated Methods - Projection displays include a highlight projector and a main projector. Highlights projected by the highlight projector boost luminance in highlight areas of a base image projected by the main projector. Various highlight projectors including steerable beams, holographic projectors and spatial light modulators are described. | 02-13-2014 |
20140204186 | HIGH DIRECTIVITY SCREENS - A theater utilizes multiple projectors that are widely spaced. The wide spacing of the projectors reduces hot spotting that occurs on flat, curved, retro-reflective, and other types of screens. The projectors are spaced widely apart and generally are placed at opposite sides of the theater. The wide spacing causes a trapezoidal distortion or effect which may be electronically compensated for by, for example, changing pixel locations on modulators of the projectors such that same (or corresponding) pixels modulated in both projectors are ultimately projected onto a same pixel area of the screen. The invention is particularly advantageous in polarization based 3D systems which generally require high directivity screens where hot spotting and related crosstalk are common. | 07-24-2014 |

20140333737 | Digital Point Spread Function (DPSF) and Dual Modulation Projection (including Lasers) using DPSF - A digital PSF for use in a dual modulation display. The invention allows the use of less than optimal point spread (PSF) functions in the optics between the pre-modulator and primary modulator of a dual modulation projection system. This technique uses multiple halftones per frame in the pre-modulator synchronized with a modified bit sequence in the primary modulator to produce a compensation image that reduces the errors produced by the sub-optimal PSF. The invention includes the application to dual modulation and dual modulated 3D viewing systems. | 11-13-2014 |
20140333835 | Multi-Half-Tone Imaging and Dual Modulation Projection/Dual Modulation Laser Projection - Smaller halftone tiles are implemented on a first modulator of a dual modulation projection system. This techniques uses multiple halftones per frame in the pre-modulator synchronized with a modified bit sequence in the primary modulator to effectively increase the number of levels provided by a given tile size in the halftone modulator. It addresses the issue of reduced contrast ratio at low light levels for small tile sizes and allows the use of smaller PSFs which reduce halo artifacts in the projected image and may be utilized in 3D projecting and viewing. | 11-13-2014 |
20150036057 | Multiple Stage Modulation Projector Display Systems Having Efficient Light Utilization - Dual or multi-modulation display systems comprising a first modulator and a second modulator are disclosed. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the first and second modulator. The display system may render highlight features within a projected image by affecting a time multiplexing scheme. In one embodiment, the first modulator may be switched on a sub-frame basis such that a desired proportion of the available light may be focused or directed onto the second modulator to form the highlight feature on a sub-frame rendering basis. | 02-05-2015 |
