  • Patent number: 8531454
    Abstract: Certain embodiments provide a display apparatus including: a selection unit configured to make a selection as to which image in images shot by which virtual cameras should be displayed on which subpixel based on the viewing position and the number of parallaxes which can be displayed; a generation unit configured to dispose the virtual camera on the coordinates of the virtual cameras in the CG space, shoot a drawing object in the CG space, and generate an elemental image based on a shot multiple viewpoint image and the selection result in the selection unit; a display unit configured to display a stereoscopic image based on the elemental image; and an optical plate configured to control light rays illuminated from the display unit to make it possible for the viewer to conduct stereoscopic viewing with a light ray interval which is wider than the shooting interval.

  • Patent number: 8441523
    Abstract: Coordinate values of an object located in a coordinate space are stored in a memory. The coordinate space is represented by a first direction, a second direction and a third direction each different. The coordinate values include first coordinate values along the first direction, second coordinate values along the second direction and third coordinate values along the third direction. A stereoscopic image of the object having a parallax along one of the first direction and the second direction is displayed. A direction of the parallax is detected. When the direction of the parallax is the first direction, the first coordinate values are subjected to a parallel projection. When the direction of the parallax is the second direction, the second coordinate values are subjected to the parallel projection.

  • Publication number: 20120062556
    Abstract: According to an embodiment, a three-dimensional image display apparatus includes a display unit; a detecting unit configured to detect an observation position of an observer relative to the display unit; a determining unit configured to determine an amount of parallax of an input image signal to be reduced as an angle increases between a normal direction of a surface of the display unit and an observation direction based on the detected observation position or as a distance decreases between the surface of the display unit and the detected observation position; and a generating unit configured to generate a multi-view image to be displayed on the display unit on the basis of the determined amount of parallax.

  • Patent number: 8106940
    Abstract: A stereoscopic image display apparatus includes a two-dimensional display device having a display surface formed of a plurality of pixels arranged in a matrix form, and an optical plate which is provided in front of the display surface of the two-dimensional display device, which includes a plurality of lenses arranged so as to be respectively associated with elemental images each including a plurality of pixels, and which controls light rays illuminated from the pixels. When at least two and less than three elemental images are illuminated in one parallax direction in the case where a position of a part or whole of a stereoscopic image is located on a side nearer a viewer than a position indicating a near-side limit value Zno or on a side farther from the viewer than a position indicating a far-side limit value Zfo, the two-dimensional display device displays black in an elemental image of one parallax in elemental images of every two parallaxes.

  • Patent number: 7948486
    Abstract: An image processing apparatus includes a first and second Z value calculators that calculate a polygon Z value and a block Z value, respectively. The polygon Z value is a coordinate value of a pixel located at a closest point to a viewpoint. The block Z value is a coordinate value of a pixel located at a closest point to the viewpoint in a block. The apparatus also includes a Z value selector that selects a Z value of a pixel closer to the viewpoint from the polygon Z value and the block Z value as an estimate Z value; and a hidden-surface removal unit that eliminates drawing of the polygon in the block when a pixel corresponding to the estimate Z value is located at a farther point from the viewpoint than a pixel located at a farthest point from the viewpoint.

  • Publication number: 20100188355
    Abstract: An object is separately located from a touch panel in a touch panel coordinate system, and visible by a user via the touch panel. A touch position detector detects the user's touch position on the touch panel. The user's touch position is converted to a touch position in a world coordinate system using a position information of the touch position detector in the world coordinate system. A half-line connecting the touch position and a view position of the user is generated in the world coordinate system. It is decided whether the half-line crosses the object using a position information of the object in the world coordinate system.
