  • Publication number: 20050179685
    Abstract: An apparatus for displaying an object such as a billboard in a virtual world is provided. An input history of a user's operation for moving a character in the virtual world is obtained. The movement track of the character in the virtual world is also obtained. The position and direction of the billboard are changed according to the input history and the movement track so that the billboard is visible to the user. For instance, on a street where the user is expected to move at a high speed, the direction of the billboard is changed so that its display surface can face the front of the character and the billboard is displayed in a position far away from the user's viewing position.

  • Publication number: 20050123041
    Abstract: An image processing apparatus capable of obtaining a novel image. An image input unit acquires frames constituting a moving image, and stores them into an image buffer. A processing execution unit reads frames to be reproduced from the image buffer as reproduction targets. An image conversion unit applies image processing to the frames to be reproduced. An image output unit outputs the frames to a monitor. A buffer adjusting unit stores the reproduced frames into the image buffer as past frames, and drops some of the frames at predetermined time intervals.

  • Patent number: 6891544
    Abstract: The present invention relates to the architecture and use of a computer system optimized for the efficient modeling of graphics. The computer system has a primary processor and a graphics processor. The primary processor has two vector processor units within it, one which is closely connected to central processor unit. Simultaneously performing complex modeling calculations on the first vector processor and CPU, and geometry transformation calculations on the second vector processor, allows for efficient modeling of graphics. Furthermore, the graphics processor is optimized to rapidly switch between data flows from the two vector processors. In addition, the graphics processor is able to render many pixels simultaneously, and has a local memory on the graphics processor chip that acts as a frame buffer, texture buffer, and z buffer. This allows a high fill rate to the frame buffer.

  • Publication number: 20050024365
    Abstract: An information processing apparatus includes a first function block which controls rendering and a second function block which controls operation modes of the first function block. The rendering is finally performed in a display unit. The second function block shifts the operation mode to a power-saving mode in the first function block when the first function block completes generation of a screen to be rendered before completion of a unit rendering period, namely, a frame period. In the event of start of next unit rendering period, the second function block, on the other hand, shifts the power-saving mode back to a normal mode in the first function block, based on a vertical synchronizing signal indicative of the start of next unit rendering period.

  • Publication number: 20040230748
    Abstract: A prefetch command control apparatus is provided. A protocol slot generation unit, when receiving from a CPU a prefetch command in which a utilization time of data to be prefetched is specified, generates a protocol slot based on the utilization time and registers it in a schedule list storage unit. When receiving a regular access command, the protocol slot generation unit registers a protocol slot in a regular protocol queue storage unit. A cost evaluation unit evaluates an issuance cost of the prefetch command based on a cache retention time of data to be prefetched and evaluates an issuance cost of the regular access command based on a resource occupation cost. A protocol issuance unit decides which command shall be issued, the prefetch command or regular access command, based on the evaluation result of these issuance costs.
