Publication number: 20110063421Abstract: To make it possible to stably provide a stereoscopic image which can be viewed by each viewer in the state where the stereoscopic effect and the sense of reality are maximized. Left eye and right eye images (images for measurement), the parallax between which is continuously or stepwise changed, are outputted beforehand to a stereoscopic image display device, and the face of the viewer viewing the images for measurement is photographed. The pupil width of the photographed viewer is measured, and based on the state of the change in the pupil width, the fusion limit of the viewer is measured and registered. In the case where a stereoscopic image for appreciation is displayed, the stereoscopic image is outputted by controlling the parallax of the stereoscopic image so as to prevent the parallax from exceeding the fusion limit of the viewer, which is measured beforehand.Type: ApplicationFiled: September 13, 2010Publication date: March 17, 2011Applicant: FUJIFILM CorporationInventor: Masakatsu KUBOTA

Patent number: 7872665Abstract: Apparatus and systems, as well as methods and articles, may operate to capture a portion of an omniscopic or omni-stereo image using one or more image capture media. The media may be located substantially perpendicular to a converging ray originating at a viewpoint on an inter-ocular circle and having a convergence angle between zero and ninety degrees from a parallel viewpoint baseline position that includes a non-converging ray originating at the viewpoint. The media may also be located so as to be substantially perpendicular to a non-converging ray originating at a first viewpoint at a first endpoint of a diameter defining an inter-ocular circle, wherein the origin of the non-converging ray gravitates toward the center of the inter-ocular circle as spherical imagery is acquired.Type: GrantFiled: May 13, 2005Date of Patent: January 18, 2011Assignee: Micoy CorporationInventor: Trent N.

Publication number: 20100259602Abstract: A method of calibrating a multi-projector image display system is provided. According to the method, non-parametric calibration data for the display system is recovered and used to generate a non-parametric model of the display system. Local parametric models relating to the display surface of the projection screen are generated and are compared with data points defined by the non-parametric calibration data to identify one or more local errors in the non-parametric calibration data. The local errors in the non-parametric calibration data are converted to data points defined at least in part by the local parametric models and the projectors are operated to project an image on the image projection screen by utilizing a hybrid calibration model comprising data points taken from the non-parametric model and data points taken from one or more local parametric models. Additional embodiments are disclosed and claimed.Type: ApplicationFiled: June 24, 2010Publication date: October 14, 2010Applicant: MERSIVE TECHNOLOGIES, INC.Inventors: Christopher O.
