摘要： 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.

摘要： 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.

摘要： 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.
