Abstract: A photographic method of a stereoscopic image or an omnidirectional image has hidden potential of creating innovative video systems and video services that have never existed before. A photo assistant tool includes: a rotator formed by a ring-shaped circular member; a first imaging section and a second imaging section provided on an upper face of the rotator; and a support base. The first imaging section and the second imaging section take a pair of parallax images. At the same time, by continuous shots taken by the first imaging section and the second imaging section while the rotator is being rotated about a center as a center of rotation, omnidirectional parallax images are obtained. Furthermore, by continuous shots taken by the first imaging section and the second imaging section while the rotator is being continuously rotated, a motion picture made up of omnidirectional parallax images as frames is taken.

Abstract: A photographing assist device for achieving stereoscopic photographing without the provision of a dedicated camera or a plurality of identical cameras. The photographing assist device comprises: a rotor made of a circular member having the shape of a ring; a camera fixing part for mounting a camera; and a support for supporting the rotor rotatably. A camera is placed on and fixed to the camera fixing part. When the rotor is rotated, the camera also makes a circular movement on the plane of rotation. Continuous shooting is performed during the rotation, whereby images shot from a plurality of points of view are obtained. A stereoscopic image or an interpolated image is obtained subsequently through image processing.

Abstract: A parameter setting unit sets a parameter used in a predetermined interpolation calculation. A calculating unit performs the predetermined interpolation calculation based upon an input parameter. A feedback unit feeds back a value obtained through the predetermined interpolation calculation to the parameter setting unit. Then, the parameter setting unit resets the parameter based upon the value obtained through the predetermined interpolation calculation. Accordingly, an image rendering apparatus easily implements nonlinear interpolation by DDA processing which performs linear interpolation using polygon node coordinates in, for example, computer graphics, and implements rendering of, for example, curved line portions quickly and with light processing loads.

Abstract: A modeling section and geometry processing section collectively generate draw data used for a series of draw processing, and a control section transfers the generated draw data to a multi-path buffer. The draw processing is executed, under control of the control section, when a multi-path controller serially reads out the draw data stored in the multi-path buffer and outputs them to a rendering engine. This successfully saves the band width necessary for transfer of the draw data from a main processor to a graphic processor, and relieve the main processor from the process load.

Abstract: A value for expressing the fraction of the area occupied by a polygon within a pixel and a value for expressing the degree of transparency of the pixel are multiplied together for each pixel. The multiplied product is reset as the degree of transparency for each pixel, according to which a color preset for each pixel composing the polygon is mixed with the colors of other pixels rendered on a two-dimensional coordinate which is substantially the same as that for the pixels composing the polygon. This allows semi-transparent polygons to be processed by anti-aliasing without being changed into opaque polygons.

Abstract: An image rendering device holds a table which contains color and brightness values at positions specified by two-dimensional coordinates, where the color values are aligned so as to express a gradation of color tone along one coordinate axis of the two-dimensional coordinate, and the brightness values are aligned so as to express a gradation of brightness along the other coordinate axis. The image rendering device finds parameters corresponding to at least one of color and brightness of a polygon to be rendered, and generates an address for referencing a two-dimensional coordinate corresponding to each pixel composing the polygon based on the parameters. The image rendering device then acquires from the table color and/or brightness values corresponding to the address for referencing the two-dimensional coordinate. This successfully realizes natural expression by the image rendering device without preparing in advance a huge number of textures.

Abstract: A rendering processing device acquires a shift value for shifting a texel coordinate value generated from the apex coordinate values of a polygon, corrects the texel coordinate value using the shift value, acquires color information from a texture table based on the corrected texel coordinate value, and then assigns the color information to the polygon. The rendering processing device thus can move patterns or the like on the surface of the polygon without moving the polygon per se.

Abstract: On a screen a file processing apparatus displays values of an attribute related to a plurality of files using a concept of weight. The weight of each file is represented in one embodiment by spherical objects submerged into the water and displayed on the screen. For example, a first spherical object represents a file whose data size is large, and is sunk near bottom. And a second spherical object represents a file whose data size is light and is floating near the water surface.

It includes a data memory in which floating point numbers are stored; an interval specifying section adapted to retrieve two or more floating point numbers from the data memory to specify an upper bound and a lower bound between which an exact value lies for each of the retrieved two or more floating point numbers; and an ALU for performing a predetermined arithmetic operation using the upper bound and the lower bound that are specified by the interval specifying section for each of the two or more floating point numbers. Faster processing with lower loads can be achieved with guaranteed accuracy as compared with conventional equivalents that are achieved only on the basis of software operations.
