Abstract: A stereoscopic image apparatus that is capable of minimizing loss of optical energy and improving quality of a stereoscopic image is disclosed. The stereoscopic image apparatus includes a polarizing beam splitter to reflect or transmit incident light based on polarization components of the light to split the light in at least three different directions, a reflective member to reflect the light reflected by the polarizing beam splitter to a screen, at least one modulator to modulate the light reflected by the reflective member and the light transmitted through the polarizing beam splitter, and a refractive member disposed in an advancing direction of light to be incident upon the polarizing beam splitter to refract the light to be incident upon the polarizing beam splitter.

Abstract: A polarization conversion system separates light from an unpolarized image source into a first state of polarization (SOP) and an orthogonal second SOP, and directs the polarized light on first and second light paths. The SOP of light on only one of the light paths is transformed to an orthogonal state such that both light paths have the same SOP. A polarization modulator temporally modulates the light on the first and second light paths to first and second output states of polarization. First and second projection lenses direct light on the first and second light paths toward a projection screen to form substantially overlapping polarization encoded images. The polarization modulator may be located before or after the projection lenses. The polarization-encoded images may be viewed using eyewear with appropriate polarization filters.

Abstract: Proposed is a stereoscopic image screening device. The stereoscopic image screening device comprising: a polarized light splitter for spatially splitting and emitting an image light emitted from a projector into transmitted light and one or more reflected lights according to polarization components; a first modulator for emitting the transmitted light on a screen by performing modulation in a way allowing different polarizations as the transmitted light is alternately emitted as a left image or a right image in a time-division scheme; and a second modulator for emitting the reflected light on the screen by performing modulation in a way allowing different polarizations as the reflected light is alternately emitted to a left image or a right image in a time-division scheme, wherein the first modulator and the second modulator are set in a manner that the phase delay of the first modulator is any one of 0λ and ½λ, and the phase delay of the second modulator is the other one of 0λ and ½λ at a specific point of time.

Abstract: First and second spatial frame regions are identified in a sequence of motion picture image frames captured at a high frame rate. Different motion blur parameters are determined for each of the first and second spatial frame regions. First and second intermediate frame sequences having frame rates less than the capture frame rate are generated from the original frame sequence. The first motion blur parameter is applied to the first intermediate frame sequence and the second motion blur parameter is applied to the second intermediate frame sequence. The first and second spatial frame regions in the corresponding first and second intermediate frame sequences are composited to produce an output frame sequence having different motion blur in different regions of the scene.

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: A 3D image pixel in a spatially multiplexed stereo 3D display includes a first left-eye subpixel and a second left-eye subpixel that are both driven when displaying the left-eye image. The 3D image pixel also includes a first right-eye subpixel and a second right-eye subpixel that are both driven when displaying the right-eye image. The subpixels may all have a square shape. Single color emitters in the subpixels of the same eye may be driven by the same electronics. A 3D image pixel in a second spatially multiplexed stereo 3D display includes a left-eye pixel driven when displaying the left-eye image and a right-eye pixel driven when displaying the right-eye image. The pixels may all have a rectangular shape, and the horizontal measurement of the pixels may be greater than the vertical measurement of the pixels.

Abstract: Liquid crystal devices are described that maintain performance of polarization/amplitude modulation under high irradiance conditions. Configurations that isolate polarizing elements under high thermal load are discussed which allow other elements, such as glass, which may be sensitive to stress birefringence to remain near optimum thermal conditions.
