Patent number: 8955975Abstract: A method is provided that includes providing a light source having a light emitting diode (LED) that emits a light. A polarization conversion system (PCS) is located adjacent the LED and has both a linear polarizer and a wave plate. A polarizing beam splitter (PBS) is adjacent the light source and an imaging device is adjacent the PBS. The wave plate of the PCS is rotated to a first position, and a first light is emitted by the LED in the first light source. This first light is converted to circular polarization. This first light travels to the PBS where it is reflected onto the imaging device. The wave plate is then rotated to a second position, and a second light is emitted by the light source. This second light is converted to circular polarization and reflects from the PBS onto the imaging device.Type: GrantFiled: November 9, 2012Date of Patent: February 17, 2015Assignee: International Business Machines CorporationInventor: Casimer M. DeCusatis

Patent number: 8933999Abstract: Margins are prevented from being produced when the amount of parallax of a stereoscopic image has been enlarged. A parallax adjustment command is applied if a stereoscopic image is displayed in an image compositing area that has been defined on a page constituting an electronic album. The amount of parallax is enlarged in response to application of a command to enlarge the amount of parallax. If enlarging the amount of parallax will cause margins to be produced when the stereoscopic image is displayed in the image compositing area on the page, then this page is replaced by a page on which an image compositing area that will not produce margins has been formed.Type: GrantFiled: August 26, 2011Date of Patent: January 13, 2015Assignee: Fujifilm CorporationInventor: Kei Yamaji

Patent number: 8866883Abstract: Tools are described for preparing digital dental models for use in dental restoration production processes, along with associated systems and methods. Dental modeling is improved by supplementing views of three-dimensional models with still images of the modeled subject matter. Video data acquired during a scan of the model provides a source of still images that can be displayed alongside a rendered three-dimensional model, and the two views (model and still image) may be synchronized to provide a common perspective of the model's subject matter. This approach provides useful visual information for disambiguating surface features of the model during processing steps such as marking a margin of a prepared tooth surface for a restoration.Type: GrantFiled: June 27, 2008Date of Patent: October 21, 2014Assignee: 3M Innovative Properties CompanyInventors: Janos Rohaly, Robert N.
