Publication number: 20130002839Abstract: A method for the recognition of stereoscopic glasses, wherein two images of an environment in front of a screen are acquired from the same point of view. A differential image is then calculated by subtracting one of the two images from the other one, and the presence of two lenses is detected within the differential image. A method is also provided for controlling the display of stereoscopic images by using the method for the recognition of glasses. Also described are the devices allowing the methods to be implemented.Type: ApplicationFiled: January 7, 2011Publication date: January 3, 2013Applicant: 3DSWITCH S.R.L.Inventors: Dario Pennisi, Antonio Caramelli

Patent number: 8334897Abstract: A direction-controlled illumination unit for an autostereoscopic display, which unit deflects light from activated illumination elements through a transmissive image reproduction means in the space in front of the display into visibility areas, from which a stereoscopic and/or monoscopic representation can be seen. The direction-controlled illumination unit contains an illumination means having illumination elements, an imaging means having imaging elements, a prism arrangement, a light-scattering means and an image reproduction means. A respective imaging element is assigned a number of illumination elements in order to deflect light in the form of a beam onto observers' eyes in a sequential manner in terms of time.Type: GrantFiled: August 28, 2007Date of Patent: December 18, 2012Assignee: Seereal Technologies S.A.Inventors: Steffen Buschbeck, Jean-Christophe Olaya

Patent number: 8289380Abstract: The present invention relates to a polarized stereoscopic display method and a device thereof. In one embodiment, the device comprises a first signal processing part for signal processing the first image and producing a first input image that is input to a first projector so that a first output beam output from the first projector corresponding to the first image is output from the first projector with a 90 degree phase difference with respect to a second output beam outputted from the second projector corresponding to the second image. The first signal processing part may comprise an image rotating part for rotating an inputted image by 90 degree, a resizing part combined with an output terminal of the image rotating part for resizing the image rotated by 90 degree corresponding to a screen and output it to the first projector.Type: GrantFiled: August 31, 2006Date of Patent: October 16, 2012Assignee: Kwangwoon University Research Institute for Industry CooperationInventors: Eun-Soo Kim, Seung-Cheol Kim

Publication number: 20120236132Abstract: One frame is divided into a first-half field and a second-half field, and each of the fields is further divided into subfields. In addition, a pixel is controlled to be turned on or off for each of the subfields to display a gradation. A right eye image is formed with a positive polarity in a first-half field of an odd block, and a left eye image is formed with a negative polarity in a second-half field. In an even block, a right eye image is formed with a negative polarity in a first-half field, and a left eye image is formed with a positive polarity in a second-half field.Type: ApplicationFiled: March 13, 2012Publication date: September 20, 2012Applicant: SEIKO EPSON CORPORATIONInventor: Nariya TAKAHASHI

Patent number: 8269821Abstract: Systems and methods are presented for processing three-dimensional (3D or 3-D) or pseudo-3D programming. The programming includes closed caption (CC) information that includes caption data and a location identifier that specifies a location for the caption data within the 3D programming. The programming information is processed to render the caption data at the specified location and to present the programming on the display. By encoding location identification information into the three-dimensional programming, a high level of configurability can be provided and the 3D experience can be preserved while captions are displayed.Type: GrantFiled: January 27, 2009Date of Patent: September 18, 2012Assignee: EchoStar Technologies, L.L.C.Inventor: John Anthony Card, II
