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: 8325222Abstract: Apparatus, systems and methods of providing respective video signals to at least two viewers using a common display are disclosed. An image from a first video signal corresponding to a left perspective of a scene and an image from a second video signal corresponding to a right perspective of the scene are alternately displayed with the display. A first shuttered filter is synchronized to the display such that the first filter is shuttered when the left perspective image is displayed and a second shuttered filter is synchronized to the display such that the second filter is shuttered when the right perspective image is displayed, thereby alternately providing left and right perspective images for perception as a 3D images. In addition, display of one or more images from an additional video signal on the display is synchronized with shuttering of one or more additional shuttered filters.Type: GrantFiled: July 14, 2009Date of Patent: December 4, 2012Assignee: Sony Computer Entertainment Inc.Inventors: Heinrich Shih Ko, Jae Won Paik, Gary Zalewski

Patent number: 8325223Abstract: A shuttered filter apparatus comprises a frame, one or more shuttered filters attached to the frame, and a tracker attached to the frame. Each shuttered filter is configured to selectively prevent a viewer from seeing through the filter in response to a signal from a controller. The tracker is configured to sense an orientation of the one or more shuttered filters relative to a video screen. The controller may use a signal from the tracker indicative of an orientation of the shutter filter(s) relative to enable shuttering when the shuttered filter apparatus is facing toward the video screen and disable shuttering when the shuttered filter apparatus is facing away from the video screen.Type: GrantFiled: July 14, 2009Date of Patent: December 4, 2012Assignee: Sony Computer Entertainment Inc.Inventors: Heinrich Shih Ko, Jae Won Paik, Gary Zalewski

Patent number: 8319827Abstract: An image signal process apparatus and a method for controlling thereof are provided. The image signal process apparatus includes a storage unit storing pixel data of an incoming frame image, a scaling filter generating one frame image by scaling the pixel data, and a controller retrieving a part of the pixel data among pixel data of the frame image stored at the storage unit, and transmitting the retrieved pixel data to the scaling filter. As a result, a process of processing a stereoscopic image may be reduced such that deterioration of an image quality may be prevented, and a data processing time may be reduced.Type: GrantFiled: May 22, 2007Date of Patent: November 27, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Eun-bae Lee

Patent number: 8310527Abstract: A system for providing respective video signals to at least two viewers is disclosed. The system includes a control unit; and a display connected to the control unit. The control unit is operable to control the display to alternately display an image from a first video signal and an image from a second video signal, to synchronize a first shuttered filter to the display such that the first filter is shuttered when the second video signal image is displayed, and to synchronize a second shuttered filter to the display such that the second filter is shuttered when the first video signal image is displayed. In this way only the first video signal image is provided to a first viewer using the first shuttered filter and only the second video signal image is provided to a second viewer using the second shuttered filter.Type: GrantFiled: July 14, 2009Date of Patent: November 13, 2012Assignee: Sony Computer Entertainment Inc.Inventors: Heinrich Shih Ko, Jae Won Paik, Gary Zalewski

Patent number: 8269824Abstract: An illuminator of an electronic endoscope system is provided with a light emission mechanism that consists of a light source emitting white light as general illumination light and an optical chopper that turns a disc at a revolution speed in front of the light source. The disc consists of transparent glass sectors and filter sectors. Each time the general illumination light passes through the filter sectors, the illuminator emits specific illumination light having different spectral characteristics from those of the general illumination light, so a CCD outputs two kinds of image signals under the general illumination light and the specific illumination light. A spectral image producer produces a spectral image of arbitrary wavelength bands from the two kinds of image signals, whereas a general image producer produces a general image from those image signals captured under the general illumination light.Type: GrantFiled: July 17, 2007Date of Patent: September 18, 2012Assignee: FUJIFILM CorporationInventor: Kazuhide Hasegawa
