  • Patent number: 7797705
    Abstract: The objective is to facilitate leasing of excess computing resources of a processor when computing resources of other processors are deficient, thereby making distributed computing more efficient. A computing resource of a processor is clustered into sub processors, and the operating status of each of the sub processors is monitored by a management processor, so that a task is assigned to a sub processor that is operated according to the magnitude of the load of information processing requested. When a request for resource leasing is made from another computer via I/O interface, a computing resource of a idle sub processor is leased.

  • Publication number: 20090318662
    Abstract: A hydrazine-fixing group such as a ketone group, a formyl group, a chlormethyl group or an amide group, which is capable of releasably fixing hydrazine, is introduced into a side chain of a synthetic resin, and hydrazine is fixed to the hydrazine-fixing group. Since a hydrazine storage resin of the present invention has a hydrazine-releasable group capable of releasing hydrazine, it is able to store hydrazine stably. In addition, hydrazine can be supplied by releasing hydrazine from the hydrazine-releasable group. Consequently, the hydrazine storage resin can be widely used in various industrial fields requiring supply of hydrazine.

  • Patent number: 7612784
    Abstract: A plurality of relative orientation detection filters having orientation coefficients that represent a relative orientation of a connected sequence of pixel drawing regions with their pixel values distributed in a predetermined pattern in a buffer memory having the same structure as an image memory, and a plurality of smoothing filters having smoothing coefficients for corresponding relative orientations, are prepared. A rendering unit draws an image to the buffer memory. A relative orientation of an edge in this image is detected by means of selecting out one relative orientation detection filter that is most suitable for the relative orientation in question. Pixel values for the edge are smoothed by using the smoothing filter according to the detected relative orientation. Then, drawing data including the smoothed pixel values are written into the image memory.

  • Patent number: 7397971
    Abstract: A first storage unit is a storage area for storing original images. Inputted to an input unit is an operation instruction from a user. An obtaining identifying unit identifies an optimal original image pair. An obtaining processing unit accesses the first storage unit to obtain the optimal original image pair. A converting unit converts scales of respective images included in the optimal original image pair into a designated scale to generate intermediate images. A corresponding point matching unit makes the corresponding areas of the intermediate images coincide. A combining unit combines the intermediate images using a predetermined ratio to generate a target image. The resultant target image is outputted from an output unit to a monitor.

  • Patent number: 7212215
    Abstract: A main CPU extracts a contour and a contour candidate, which are visually important parts of an image to be rendered, according to, for example, polygon data representing an image of one frame. Further, a GPU performs rendering on data stored in a graphic memory according to the polygon data representing the image. Moreover, the GPU performs antialiasing on the contour and contour candidate extracted by the main CPU. Then, the GPU overwrites data representing the antialiased contour and contour candidate onto the data representing the image stored in the graphic memory.

  • Patent number: 7102639
    Abstract: An image processing apparatus includes an auxiliary storage device 19 stored first data of a given object image higher in LOD level, a main memory 11 stored second data of the given object image lower in the LOD level than the first data, a CPU 10, and a GPU 18. The CPU 10 calculates an apparent speed of the object image on a screen, and determines data to be used in the geometry processing of the object image to one of the first data and the second data in accordance with the apparent speed. The GPU 18 takes in the first data (or the second data) from the auxiliary storage device 19 (or the main memory 11) to conduct the rendering process in the case where the geometry processing is conducted by using the first data (or the second data).

  • Patent number: 7081894
    Abstract: The picture drawing method is in a graphics computer, a special effect device or a video game machine. Data required for picture drawing is generated by pre-processing by a pre-processor 32 based on a drawing command for drawing a picture model defined by the combination of unit figures, and pixel data is generated on the unit figure basis by texture mapping based on the generated data for drawing a picture on a frame buffer 18. The texture data required by a drawing engine 33 is transferred in the pre-processing stage from a texture area on the frame buffer 18 to a texture cache 33F, and the pre-processor 32 and the drawing engine 33 are operated in pipelining. This enables texture mapping or MIP mapping without halting picture drawing, while reducing the number of times texture memory accessing and the accessed time for raising the overall picture drawing speed.

  • Patent number: 7075533
    Abstract: A system performs refraction mapping for an image having an object, the object being viewed along at least one line of sight and at least partially through a boundary of first and second at least semi-transparent media. The boundary defines at least one normal vector at one or more intersections of the line of sight and the boundary. The system includes: a perspective transformation unit operable to project a three-dimensional version of the object on a two-dimensional texture plane using a perspective view transformation algorithm to obtain texture addresses of the object, the texture plane being perpendicular to the line of sight and the transformation being performed without regard to refraction; and a refraction determination unit operable to obtain at least one refraction vector for at least one of the texture addresses, a given refraction vector being a function of a component of the at least one normal vector that is parallel to the texture plane.
