  • Patent number: 7817153
    Abstract: A rendering apparatus includes a rasterizer, pixel processing units and memories. The rasterizer generates pixels corresponding to graphics. The pixel processing units execute rendering operations for the pixels generated by the rasterizer. The pixels rendered by the same pixel processing unit are positioned substantially equidistantly and isotropically within a rendering area. The memories are provided in association with the respective pixel processing units and store data of the pixels rendered by the associated pixel processing units.

  • Publication number: 20100259621
    Abstract: An image processing apparatus includes a discontinuity detecting unit configured to detect a discontinuity between frames in stream data and, when detecting a discontinuity, add predetermined discontinuity information and output the image data and header information, a FIFO configured to store the image data and the header information in association with each frame, and a frame-to-be-processed determining unit configured to determine, for continuous frames, elapsed time from the start of the stream on the basis of the PTSs of two continuous frames, determine, for a discontinuous frame, elapsed time based on the PTS and frame rate of a frame preceding or succeeding the point at which a discontinuity exists, and determine a frame to which image processing is to be applied based on the determined elapsed time and time intervals f set for specifying a frame to which the image processing is to be applied.

  • Publication number: 20090284627
    Abstract: An image processing method includes photographing an object by a camera via a filter, separating image data, which is obtained by photographing by the camera, into a red component, a green component and a blue component, determining a relationship of correspondency between pixels in the red component, the green component and the blue component, with reference to departure of pixel values in the red component, the green component and the blue component from a linear color model in a three-dimensional color space, and finding a depth of each of the pixels in the image data in accordance with positional displacement amounts of the corresponding pixels of the red component, the green component and the blue component. The image processing method further includes processing the image data in accordance with the depth.

  • Publication number: 20080211806
    Abstract: A setup section acquires vertex data including at least homogeneous coordinate and window coordinate relevant to two vertexes of rendering primitive, that is, segment. An edge coefficient calculation unit calculates an edge coefficient used for determining whether or not a pixel exists inside a projection area (parallelogram) of the segment. A bounding box calculation unit calculates a bounding box of the projection area from at least one vertex data of two vertexes and the edge coefficient. A start point determination unit classifies the projection area based on a combination of the edge coefficient, and determines scan start point and scan performing direction of the bounding box in accordance with the classification. An edge function initial value determination unit determines an edge function of the pixel corresponding to the scan start point as an initial value, and carries out a DDA, and thereby, generates setup data for rasterizing.

  • Patent number: 7355604
    Abstract: An image rendering method includes generating pixels in accordance with graphic information, determining a direction of anisotropy of a footprint obtained by projecting the pixel on a texture on which a set of texels are disposed on uv-coordinates, and executing sampling of a MIP map in accordance with the direction of anisotropy, and executing texture mapping for the pixel. The direction of anisotropy is determined by comparing lengths in at least three different directions of the footprint on the texture.
