Patent number: 8684531Abstract: 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: GrantFiled: December 28, 2010Date of Patent: April 1, 2014Assignee: Vision3D Technologies, LLCInventors: Ken Mashitani, Masutaka Inoue, Hideyuki Kanayama, Takashi Ikeda, Takahisa Ando, Kazuhiro Arai, Ryuhei Amano

Patent number: 8562138Abstract: In a projection display device, a polarization converting element is provided between an imager and a refracting optical system for converting a polarization direction of light after modulation into a direction radially extending from the center of the optical axis of the refracting optical system. Light transmitted through the polarization converting element is incident onto the refracting optical system in a state of P-polarized light or a state close to the state of P-polarized light. Thereby, the transmittance of light through the refracting optical system is made substantially uniform and increased.Type: GrantFiled: September 23, 2011Date of Patent: October 22, 2013Assignee: SANYO Electric Co., Ltd.Inventor: Ryuhei Amano

Patent number: 8220937Abstract: An optical position of a display device with respect to an optical axis of a projection optical system is displaced in a direction perpendicular to the optical axis in accordance with a change in the size of a projected image. For instance, a transparent flat plate is disposed in front of a projection lens, and the transparent flat plate is tilted in association with a rotation of a zoom adjustment ring. As the transparent flat plate is tilted, the apparent position of the display device relative to the projection lens is displaced in the direction perpendicular to the optical axis of the projection optical system. Thereby, the projected image on a screen is located at a proper position corresponding to a zoom state. Tilt control of the transparent flat plate is realized by a cam mechanism, for instance.Type: GrantFiled: January 25, 2008Date of Patent: July 17, 2012Assignee: SANYO Electric Co., Ltd.Inventors: Ryuhei Amano, Takashi Ikeda, Takashi Miwa

Publication number: 20120077172Abstract: A digital camera (1) performs shooting such that each student within a classroom is included in a subject, uses an optical flow to detect the action of standing up from a chair or the action of moving a mouth by a student who needs to be a speaker, thus specifies the position of the speaker (any of the students) on a shooting image and extracts image data on the face portion of the speaker. A PC (2) uses a projector (3) to display a material on a screen (4), and superimposes and displays, when the extracted image data is transferred from the digital camera (1), a picture of the face of the speaker on the screen (4) based on the extracted image data.Type: ApplicationFiled: December 2, 2011Publication date: March 29, 2012Applicant: SANYO ELECTRIC CO., LTD.Inventors: Tohru WATANABE, Ryuhei AMANO, Noboru YOSHINOBE, Masafumi TANAKA, Kiyoko TSUJI, Kazuo ISHIMOTO, Toshio NAKAKUKI, Kaihei KUWATA, Masahiro YOSHIDA
