Patent number: 8248512Abstract: The present invention provides full-parallax images having high spatial resolution in real time. An image-capturing optical unit (21) includes a plurality of prismatic mirrors (41) which rotate at a predetermined period. The side surface of each of the prismatic mirrors (41) reflects a light beam from an object. A camera receives the light beam from the object reflected by the prismatic mirrors (41) in order to capture an image of the object. On the other hand, a display optical unit (32) includes a plurality of prismatic mirrors (51) which rotate in phase with the prismatic mirrors (41) at the same period. A projector emits a light beam corresponding to the image of the object captured by the camera, and such a light beam is reflected by the prismatic mirrors (51). A user may view an image corresponding to the light beam reflected by the prismatic mirrors (51).Type: GrantFiled: June 12, 2009Date of Patent: August 21, 2012Assignee: Sony CorporationInventors: Tetsujiro Kondo, Kenji Tanaka

Patent number: 8240854Abstract: An autostereoscopic display device includes a reflection layer for reflecting at least a portion of incident light, a polarization conversion layer arranged over the reflection layer, and an array of lenticular elements arranged over at least a portion of the polarization conversion layer and including a birefringent material. Light having a first state of polarization is configured to pass through the lenticular element array without substantial lenticular element focusing, where the polarization state is transformed by the polarization conversion layer such that the reflected light has a second state of polarization. Light having the second polarization state passes through the lenticular element array with the lenticular element focusing to provide multiple views to different viewing locations.Type: GrantFiled: December 12, 2007Date of Patent: August 14, 2012Assignee: Koninlijke Philips Electronics N.V.Inventors: Marcellinus Petrus Carolus Michael Krijn, Patrick Peter Elizabeth Meuwissen, Hans Zuidema, Willem Lubertus Ijzerman, Siebe Tjerk De Zwart, Oscar Hendrikus Willemsen

Publication number: 20120200916Abstract: A method for creating a three-dimensional multi-stereoscopic viewing apparatus includes determining characteristics of an electronically illuminating color matrix panel display having first a pixel arrangement. The method also includes determining a specification for a lenticular lens configured to convert the first pixel arrangement to a second pixel arrangement and placing the lenticular lens on the display panel. The specification for the lenticular lens is determined by calculating a viewing distance from a refraction index, a width of the display panel, and an average distance between human eyes. Determining the specification for the lenticular lens also includes determining a viewing angle that maximizes viewing characteristics and determining characteristics of the lenticular lens.Type: ApplicationFiled: November 23, 2011Publication date: August 9, 2012Applicant: MAGNETIC MEDIA HOLDINGS INC.Inventor: Brad Bent-Gourley
