Abstract: A polarization conversion system (PCS) is located in the output light path of a projector. The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.

Abstract: Three-dimensional display systems may include polarized displays that polarize light emitted from a first set of areas of the display with a first polarization for a first eye of the viewer and that polarizes light emitted from a second set of areas of the display with a second polarization for a second eye of the viewer. This may result in dark areas being perceived by a viewer when viewed through polarized 3D glasses. Systems and technologies according to this disclosure may include 3D glasses that have a lenses configured to redirect a portion of incoming light in a first axis to at least partially illuminate the dark areas.

Abstract: A third imaging unit including a pixel not having a polarization characteristic is interposed between a first imaging unit and a second imaging unit including a pixel having a polarization characteristic for each of a plurality of polarization directions. A depth map is generated from a viewpoint of the first imaging unit by matching processing using a first image generated by the first imaging unit and a second image generated by the second imaging unit A normal map is generated on the basis of a polarization state of the first image. Integration processing of the depth map and the normal map is performed and a depth map with a high accuracy is generated. The depth map generated by the map integrating unit is converted into a map from a viewpoint of the third imaging unit, and an image free from deterioration can be generated.

Abstract: A stereoscopic light recycling device is provided. A beam splitter is constructed of substantially orthogonally polarizing material on which divergent image light is received and is positioned at an angle to a source of the divergent image light. A phase shifting optic includes a reflective surface coated by a phase shifting film and is positioned at an angle non-perpendicular to at least a portion of the image light from the beam splitter. The angle of the phase shifting optic is dependent on the angle of the beam splitter.

Abstract: The present invention relates to a time-multiplexed stereoscopic 3d projection system wherein the image-beam from a digital cinema projector is separated by a polarization beam-splitting element into one primary image-beam possessing a first state of polarization and at least one secondary image-beam possessing a second state of polarization. Polarization modulators are provided in order to modulate the polarization state for each of said primary and secondary image-beams thereof and arranged so that all left-eye images possess a first modulated state of polarization and all right-eye images possess a second modulated state of polarization. Additionally, there is provided one uniaxial condensing lens and at least one uniaxial expanding lens in order to minimize the optical path-lengths for each of said primary and secondary image-beams thereof, hence enabling said stereoscopic 3d projection system according to the present invention to operate together with projectors having a shorter throw-ratio as compared to other prior-art technologies.

Abstract: A three-dimensional imaging system relies on effective native image resolution reduction in order to provide an array of pixel clusters, or voxels, with each pixel of the voxel representing a pixel of the image from a unique viewing angle. A 16-megapixel screen having 16-pixel voxels results in a screen having an image capacity downgraded to a 1-megapixel screen capable of showing sixteen different viewing angles. The system can be set up as a rear-projection screen or as a reflective screen illuminated by a front projector. The invention is best implemented with projectors and screens that represent all colors at a single physical location, such as a 3-panel LCD color-combinant projector or a DLP projector, either single or triple chip type. When the RGB sub-pixels are non-coincident, the viewers will see color artifacts that detract from the viewing experience.

Abstract translation: 偏振转换系统（PCS）位于投影仪的输出光路中。 PCS可以包括偏振分束器，偏振旋转元件，反射元件和偏振开关。 通常，投影仪输出随机偏振光。 该光被输入到PCS，其中PCS在偏振分束器处分离p偏振光和s偏振光。 P偏振光在第一路径上被引向偏振开关。 s偏振光在穿过偏振旋转元件（例如半波片）的第二路径上通过，从而将其变换为p偏振光。 反射元件将沿着第二路径的变换的偏振光（现在p偏振光）引向偏振开关。 第一和第二光路最终定向到投影屏幕，以在使用偏振光进行三维观看的电影应用中共同形成更亮的屏幕图像。
