Patent number: 8982190Abstract: There is provided an imaging element that photographs multiple viewing point images corresponding to images observed from different viewing points and an image processing unit separates an output signal of the imaging element, acquires the plurality of viewing point images corresponding to the images observed from the different viewing points, and generates a left eye image and a right eye image for three-dimensional image display, on the basis of the plurality of acquired viewing point images. The image processing unit generates parallax information on the basis of the plurality of viewing point images obtained from the imaging element and generates a left eye image and a right eye image for three-dimensional image display by 2D3D conversion processing using the generated parallax information. By this configuration, a plurality of viewing point images are acquired on the basis of one photographed image and images for three-dimensional image display are generated.Type: GrantFiled: July 17, 2012Date of Patent: March 17, 2015Assignee: Sony CorporationInventors: Seiji Kobayashi, Atsushi Ito

Patent number: 8982181Abstract: The invention provides a complete system for three-dimensional (3D) (stereo) still photography in a digital format. This includes capturing the image or photo, viewing, printing and projecting it. Intermediate steps would include downloading images to a computer, editing, enhancing or modifying, saving, recording photo images to other storage medium, and the printing of still photos. This invention is a significant advancement of the traditional analog film stereo slides, in that the digital format will allow viewing of the image in the camera in 3D, prior to, during, immediately after exposure and at any other time after exposure. With significant computer processing capability after exposure in editing, enhancing, color correcting, adding text and art, the images are further improved. The system includes the ability to view images, in 3D (stereo), in the camera, in a hand held viewer, on a computer screen on a standard television set as well as printed pairs or in anaglyph formats.Type: GrantFiled: June 13, 2007Date of Patent: March 17, 2015Assignee: Newbery Revocable Trust IndentureInventor: Billy Newbery

Publication number: 20150070473Abstract: This invention discloses using one or more color-encoded fringe patterns for optically, three-dimensionally measuring an object's shape. In one embodiment, a color-encoded fringe pattern comprising a plurality of fringes that are modulated in intensity is configured as follows. An individual fringe selected from the fringes comprises a colored line at a location on the fringe width. The colored line has a line width that is substantially narrower than the fringe width in order that the colored line has a substantially similar intensity over the line width. The individual fringe excluding the colored line has a fringe color that is substantially uniform over the individual fringe. The fringe color is substantially different from the line color. Fringe colors of all the fringes are substantially similar, thereby enabling a major portion of the color-encoded fringe pattern to provide a substantially-uniform illumination color for projection onto the object.Type: ApplicationFiled: September 12, 2013Publication date: March 12, 2015Applicant: HONG KONG APPLIED SCIENCE AND TECHNOLOGY RESEARCH INSTITUTE COMPANY LIMITEDInventor: Zhao WANG

Patent number: 8976232Abstract: A distance determining section increases a convergence point distance by a distance proportionate to an operation of an up key. The distance determining section reduces the convergence point distance by a distance proportionate to an operation of a down key. A target convergence point distance is incremented by 1 m per pressing operation of the up key. The target convergence point distance is decremented by 1 m per pressing operation of the down key. A shift amount setting section converts the target convergence point distance into a shift amount that corresponds to the target convergence point distance. The shift amount is set to an image shifting section. The image shifting section shifts each cut out region by the shift amount from a reference position and cuts out viewpoint images with the cut out regions from original left and right viewpoint images. Thus, the parallax-adjusted viewpoint images are produced.Type: GrantFiled: April 29, 2014Date of Patent: March 10, 2015Assignee: FUJIFILM CorporationInventor: Tomoyuki Mizuta
