An apparatus is disclosed, the apparatus including a lens body configured to fit within a standard cinematic movie camera, the lens body including a plurality of optical elements including a plurality of lenses and a sensor. The plurality of optical elements is arranged to receive two channels of visual images and provide the two channels of images to the sensor.

Stereoscopic lens for digital cameras

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

An enhanced liquid crystal display design is provided having relatively fast response time particularly useful in high speed or highly intense applications, such as stereoscopic or autostereoscopic image display. The liquid crystal display device is configured to display stereoscopic images, and comprises an LCD panel and control electronics configured to drive the LCD panel to a desired 10 stereoscopic display state. The control electronics are configured to employ transient phase switching and overdrive the LCD panel to a desired state to enable relatively rapid display of stereoscopic images.

Stereoscopic flat panel display with synchronized backlight, polarization control panel, and liquid crystal display

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 multi-view distribution format is described for stereoscopic and autostereoscopic 3D displays. In general, it comprises multi-tile image compression with the inclusion of one or more depth maps. More specifically, it provides embodiments that utilize stereoscopic images with one or more depth maps typically in the form of a compressed grey scale image and, in some instances, incorporates depth information from a second view encoded differentially.

Stereoscopic image format with depth information

A device and method for converting one stereoscopic format into another. A software-enabled matrix is used to set forth predefined relationships between one type of format as an input image and another type of format as an output image. The matrix can then be used as a look-up table that defines a correspondence between input pixels and output pixels for the desired format conversion.

Stereoscopic format converter

A system and method for determining an intermediate stereoscopic representation, thus offering adjustable interaxial separation values, is presented. The design comprises obtaining a first image using a first image collecting device and substantially simultaneously obtaining a second image using a second image collecting device. The two recoding devices are physically separated by a distance, and the second image may be combined with the first image to form a stereoscopic image. The design further determines the intermediate stereoscopic representation based on aspects of the first image combined, typically algorithmically, with aspects of the second image.

Algorithmic interaxial reduction

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 projection design configured for use with a projector having a projector lens is provided. The device includes at least one pi-cell or pi-cell electro-optical modulator in combination with a wire grid polarizer mounted proximate the pi-cell(s). The design may include a cleanup polarizer between the pi-cell(s) and the wire grid polarizer and optionally a protective window between the wire grid projector and projection lens. The device may be oriented at an angle substantially differing from the axis of the projector lens. The resultant device includes spacing for airflow and can offer improved performance, particularly in heating, over designs previously available.

An active eyewear method and system for viewing stereoscopic images is provided. The eyewear comprises polarization altering elements, such as twisted nematics or super twisted nematics, configured to receive light energy and rotate the polarization of light energy passing therethrough, and linear polarizers having polarization axes oriented in substantially identical orientations orthogonal to the first axis of polarization. The linear polarizers receive light energy from the polarization altering elements. The method comprises transmitting light energy through a sheet polarizer having an first axis of polarization, receiving the light energy with two polarization altering elements, each polarization altering operating out of phase with the other and in synchrony with a video field rate associated with the transmitting, and passing the light energy through two linear polarizers having substantially identical axes of polarization orthogonal to the first axis of polarization.
