  • Patent number: 8264477
    Abstract: An image display device is provided with a display section (10) for displaying a two-dimensional image on a screen; a microlens array board (22), which is arranged in an optical path of display light constituting the two-dimensional image, and transmits the display light to display an actual image of the two-dimensional image on an imaging plane positioned in a space on a side opposite to the screen; and a display control section (100) for controlling the display section (10) to perform blocking process to have a part of an actual object on a side further than the imaging plane not seen by an observer who observes the imaging plane.

  • Patent number: 8243125
    Abstract: An image display device capable of detecting an object in a space where a 3D visualized image is formed without feeling the existence of a mechanism for position detection. The image display device includes: display unit (11) for displaying a 2D image (1); an optical panel (12) arranged in front of an image display plane (15a) of the display unit (11) and forming a 3D visualized image (2) based on the 2D image (1) in a forward space (3) spreading in front of the optical panel (12); recognition unit arranged behind the optical panel (12) for optically recognizing the an object (5) coming into the forward space (3) via the optical panel (12); and position detection elements (14) for detecting the coming position of the object (5) into the forward space (3) according to the recognition result by the recognition unit.

  • Publication number: 20100066662
    Abstract: An image display device makes it possible to easily display a stereoscopically two-dimensional image and to improve its direction effect. A display device includes a first display for displaying a first image on a first screen, an image transmission element that is set in a light path for a display light component of the first image and that transmits the display light component of the first image so that a real image of the first image is displayed on an image forming surface positioned at a space on a side opposite to the first screen as a stray image. Further, the display device includes a. controller for controlling the first display so that at least one icon out of a plurality of icons (A-H) is displayed as a stray image disposed along a virtual path with a predetermined shape set in a real space portion including the first mentioned space.

  • Publication number: 20100007602
    Abstract: An image display device easily displays a stereoscopically two-dimensional image, improving its direction effect and interactivity. A first display displays a first image on a first screen. An image transmission element in a light path for a display light component of the first image transmits the display light component of the first image, displaying a real image of the first image on an image forming surface positioned at a distance on a side opposite the first screen as a stray image. A second display displays a second image on a second screen as a directly visible image so the stray image is observable from an observation position. A position detecting element outputs a position signal corresponding to detected object position. A control element controls the first or second display according to the output position signal so the stray and/or directly visible image changes correspondingly with the position of the object.

A first display displays a first image on a first screen, an image transmission element is in a light path for a display light component of the first image and transmits the display light component of the first image so a real image of the first image appears on an image forming surface opposite the first screen as a stray image. A second display displays a second image on a second screen as a directly visible image so the stray image is observable from an observation position. A controller controls at least either the first or second display based on a relative position in a predetermined spot displayed in the directly visible image with respect to an intersection line of the image forming surface and the second screen so the stray and/or directly visible image changes.
