A method and system for reducing visual ghost artifacts in plano-stereoscopic image transmissions is provided. Such visual ghost artifacts are reduced by retrieving a non-linear image representation comprising left and right image representations using an image processor, where each of the left and right image representations have a plurality of color component sub-images. The non-linear left and right image representations are transformed into respective linear left and right image representations. A left or right image compensation signal is generated by applying the determined at least one ghosting coefficient to its associated one of the plurality of color component sub-images. A respective compensated right or left image is generated by subtracting the left or right image compensation signal from the uncompensated linear left or right image representation.

Ghost-compensation for improved stereoscopic images

A method for demultiplexing frames of compressed image data is provided. The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.

Demultiplexing for stereoplexed film and video applications

A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.

Enhanced ZScreen modulator techniques

A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.

Stereoplexing for film and video applications

A method and system for projecting linearly polarized stereoscopic images to a viewer that results in increased viewer head-tipping capabilities is provided. The design includes projecting linearly polarized light energy toward a screen and providing the viewer with a set of linearly polarized eyewear configured to receive the linearly polarized light energy projected to the screen and transmit a right perspective view to a right eye of the viewer and a left perspective view to a left eye of the viewer. Projecting comprises performing a noise reduction technique to reduce crosstalk in linearly polarized light energy images projected.

Projection of stereoscopic images using linearly polarized light

A method for multiplexing a stream of stereoscopic image source data including a series of left images and a series of right images combinable to form a series of stereoscopic images is provided. The primary application is for video applications, but film applications are also addressed. The method includes removing pixels from the stereoscopic image source data to form left images and right images and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed alone or in combination, and selected or predetermined regions or segments from uncompressed images may have more pixels removed or combined than other regions.

Stereoplexing for video and film applications

An apparatus and method for producing a screen is provided. The method includes propelling a quantity of paint comprising metallic flakes, such as aluminum flakes, toward the screen. The method also includes applying at least one magnetic field in a vicinity of the screen, wherein applying the at least one magnetic field causes at least one metallic flake in the quantity of paint to be oriented relative to the screen in a substantially preferred orientation, thereby producing a screen exhibiting beneficial projection qualities, such as brightness. The magnetic field(s) applied may be unsymmetric in the time domain of, for example, an AC component of the magnetic field.

Enhanced projection screen

An apparatus including a selection device and a multiple mode display device is disclosed. The multiple mode display device has a lens sheet including a plurality of individual lenticules forming a lenticular surface, an electro-optical modulator positioned adjacent the lens sheet, and a display device comprising a display surface. Alternatively, a multiple mode display arrangement is disclosed, having a lens sheet including a plurality of individual lenticules forming a lenticular surface and a display device comprising a display surface. The display device is positioned behind the lens sheet, thereby enabling viewing images transmitted in at least a planar mode and a stereoscopic mode.

Multiple mode display device

A system and method for projecting stereoscopic images using a multiple projector arrangement is provided. The design comprises transmitting a first field train from the first projector, the first field train comprising first projector left and right images and concurrently transmitting a second field train from the second projector, the second field train comprising second projector left and right images. The first projector left image is transmitted by the first projector at substantially a same time as the second projector right image is transmitted by the second projector. Alternately, the design comprises transmitting a first field train from the first projector, the first field train comprising first projector left images alternating with first projector right images, and concurrently transmitting a second field train from the second projector, the second field train comprising second projector left images alternating with second projector right images. A quasi-interlacing technique is also provided.
