A keyword acquiring unit transmits a keyword acquisition request to a first server serving as a keyword providing service, and receives a keyword from the first server. An information acquiring unit transmits an acquisition request of information related to the keyword to a second server serving as an information providing service, and receives the information from the second server. A cover unit presents information acquired by the information acquiring unit to a user. An input unit receives selection of at least one of information presented by the cover unit. A service acquiring unit transmits a search request based on the keyword related to information selected at the input unit to a third server serving as a search service, and acquires a search result from the third server. A socket unit presents the search result to the user.

Information presenting apparatus, information presenting method and computer-readable recording medium

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.

Display apparatus and stereoscopic image display method

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.

Apparatus and method for drawing a stereoscopic image

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.

Stereoscopic image display apparatus and stereoscopic image producing method

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.

Apparatus and method for performing hidden surface removal and computer program product

Apparatus includes unit storing CG data containing data about coordinate transformation, camera, geometry, light source, and texture, unit transforming coordinate system of CG data into camera-coordinate system, unit calculating intersections of object and ray vectors passing through sampled points, unit calculating 3D motion vectors, unit calculating color values at intersections, unit assigning object IDs of intersections at 3D coordinates to intersections, unit projecting intersections and 3D motion vectors onto plane, and calculating 2D coordinates at intersections and 2D motion vectors at intersections, unit storing 2D coordinates, 2D motion vectors, color values, and object IDs together as low-resolution video data, unit calculating intermediate-resolution video data by superimposing low-resolution video data of current frame onto low-resolution video data of frames temporally different from current frame, unit calculating high-resolution video data by filtering intermediate-resolution video data, unit storing high-resolution video data, and unit presenting high-resolution video data.
