Publication number: 20110193861Abstract: A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.Type: ApplicationFiled: April 18, 2011Publication date: August 11, 2011Applicant: SANYO ELECTRIC CO., LTD.Inventors: Ken MASHITANI, Goro Hamagishi, Satoshi Takemoto

Publication number: 20110157555Abstract: An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.Type: ApplicationFiled: December 28, 2010Publication date: June 30, 2011Applicant: SANYO ELECTRIC CO., LTD.Inventors: Ken MASHITANI, Masutaka INOUE, Hideyuki KANAYAMA, Takashi IKEDA, Takahisa ANDO, Kazuhiro ARAI, Ryuhei AMANO
