摘要： Chromatic aberration can be reduced and extreme projection angles can be allowed in a projection system by modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light, causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth.

摘要： The present invention discloses methods of digitally converting 2D motion pictures or any other 2D image sequences to stereoscopic 3D image data for 3D exhibition. In one embodiment, various types of Image data cues can be collected from 2D source images by various methods and then used for producing two distinct stereoscopic 3D views. Embodiments of the disclosed methods can be implemented within a highly efficient system comprising both software and computing hardware. The architectural model of some embodiments of the system is equally applicable to a wide range of conversion, re-mastering and visual enhancement applications for motion pictures and other image sequences, including converting a 2D motion picture or a 2D image sequence to 3D, re-mastering a motion picture or a video sequence to a different frame rate, enhancing the quality of a motion picture or other image sequences, or other conversions which facilitate further improvement in visual image quality within a projector to produce the enhanced images.

摘要： Embodiments of the present disclosure are directed towards a method of encoding image frames into a multiplexed frame, and a corresponding method of decoding the multiplexed frame. The encoding method includes modifying image frames to generate corresponding processed frames, and generating masking data that indicates how an output frame can be produced from one of the processed frames and another of the processed frames. The processed frames and the masking data can be combined to form a multiplexed frame. The decoding method includes receiving a multiplexed frame containing processed frames and masking data, and unpacking the multiplexed frame to identify the processed frames and the masking data. Once unpacked, an output frame can be generated from the processed frames by combining one of the processed frames with another of the processed frames according to the masking data.

摘要： A theatre system is described that includes a screen and a projection system. The projection system includes a first mirror and a second mirror that are positionable within axes for imaged light and between projection lenses of projectors and the screen. The axes include a first axis and a second axis. The first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and second axis along a dimension by which the screen is curved.

摘要： Optical systems are provided that include illumination sources, micro-mirror array optical modulators, and an optical element. The micro-mirror array optical modulators can selectively modulate light beams, redirect light by diffraction and reflection, and provide an output modulated light beam that exhibits a diffraction handedness dependent on the spectral bandwidth of the light incident thereupon. The optical element has a color dependent aperture that defines portions of output modulated light beams that are transmitted and remaining portions that are blocked. An efficiency and contrast of each the output modulated light beams acquired by the optical element can be independently determined by a narrow spectral bandwidth of each of the light beams, the spectral characteristics of the color dependent aperture, and the diffraction handedness of the micro-mirror array optical modulators for the associated spectral bandwidth.

摘要： A digital image sequence with multiple image frames can be enhanced. An appearance graph can be determined from the digital image sequence. The appearance graph includes prime layer nodes. Each prime layer node can represent a distinctive visual style. A prime layer image sequence can be computed for each prime layer node that matches the visual style represented by the prime layer node. An enhanced image sequence can be generated by blending at least two prime layer image sequences as defined by the appearance graph.
