Abstract:
A method and system are disclosed for differential distortion correction for use in the three-dimensional (3D) projection of film-based or digital images. A compensation transform determined based on distortion information can be applied to image data to compensate for distortions in stereoscopic images for 3D projection. Different approaches can be used for obtaining the compensation transform.
Abstract:
A system and method for use in projecting stereoscopic images for three-dimensional presentation are disclosed. The system includes a dual-lens configuration for imparting different circular polarizations to two sets of images such that one set of images has a polarization orientation orthogonal to that of the other set of images. The dual-lens system includes at least one component for enhancing heat transfer among various elements in the system.
Abstract:
ABSTRACT OF THE DISCLOSURE The processing images in a telepresence system commences by establishing, at a first station, first orientation data indicative of an orientation of a first audience member relative to each of a first and second image display devices at the first station. Thereafter, the first station receives an incoming first image of a second audience member at a second station of the telepresence system, along with second orientation data indicative of an orientation of the second audience member relative to a first image capture device at the second station. The first station processes the first image for display on a selected one of the first and second image display devices, in accordance with the first and second orientation data so upon display, the image of the second audience appears to coexist in superposition with an image of the first audience member in a common environment.
Abstract:
A system and method are disclosed for displaying different captions for selective viewing. A display is used for showing the captions in different color and/or polarization combinations, and color-selective filters and/or polarizers are used for separately viewing the individual captions.
Abstract:
A method and apparatus are described for monitoring frame alignment status and correcting misalignment for film (500) in a stereoscopic 3D projection system, in which gap indicia (530, 531, 532; 540, 541, 542) are provided onto the film in a gap (521; 522) between images, whether the images (L1, R1; L2, R2) belong to the same frame (111, 112) or different adjacent frames (112, 113). Thus, gap indicia are positioned in at least one of an interframe gap (522) and an intraframe gap (521) of the stereoscopic film (500). During projection of the film, presence or absence of the gap indicia is used to determine a frame alignment status. Frame misalignment is then easily diagnosed and corrected. Characteristics of the gap indicia are modified for improving frame alignment diagnosis.
Abstract:
A method and system are described for projecting stereoscopic images using circularly polarized light with at least one polarizer for limiting the amount of light or radiant energy reaching a projection lens system and associated optical elements, and system configurations are discussed with respect to desired performance characteristics.
Abstract:
A method for crosstalk compensation of stereoscopic images for three-dimensional projection is disclosed. The method can be used for producing a stereoscopic presentation containing stereoscopic image pairs that incorporate density or brightness adjustments to at least partially compensate for crosstalk contributions from images exhibiting differential distortion.
Abstract:
A method and system for monitoring a display venue are disclosed. One method involves receiving information generated by an audience in response to a request associated with content provided to the audience at a display venue, and determining at least one condition at the display venue based on the information.
Abstract:
Both linearly and circularly polarized glasses (504, 508) are used to resolve two-color anaglyph images (502). Linearly polarized glasses also are used to resolve circularly polarized images and vice versa. Modified two-color anaglyph glasses may be used to resolve standard linearly and circularly polarized images.
Abstract:
The sharing an image of a local participant in a group with at least one other participant in that group commences by establishing, for that local participant, orientation information indicative of an orientation of the local participant relative to a display screen and a video camera. The local participant sends his or her image of the local participant along with the orientation information to at least one other participant. The orientation information enables display of the image of the local participant with a common orientation recognized by the at least one other participant.
