    Abstract: A card game apparatus includes a large-size panel display, a main control unit that controls screens on the large-size panel display, and a plurality of terminal apparatuses that are communicably connected to the main control unit. A game player purchases an integrated circuit card and, for example, eleven player cards on each of which, a soccer player's photograph is printed. When the game player arranges the player cards on a player card arrangement panel of one of the terminal apparatuses, card data recorded on the back of the player card will be read by an internal image sensor. Then, a team is organized by the player cards, and a game starts. The game player can direct a player's position and formation by changing placement of the player card.

  • Patent number: 7027600
    Abstract: The audio signal processing device of the present invention arranges objects in a virtual three-dimensional space and generates audio signals by performing, at a prescribed listening position, audio simulation to sounds generated from a prescribed sounding position. This invention is characterized in that the sound field space subject to audio simulation is structured by combining spatial objects and audio simulation is performed thereto. Here, “spatial object” shall mean the space (sound field space) for audio simulation which was simply modeled in order to simplify audio simulation, and is a virtual object provided with prescribed audio parameters. The sound field space is structured by combining these spatial objects.

  • Patent number: 6543770
    Abstract: The present invention aims to reverse and transport a card in an automated card game machine, and relates to a card reversing device that reverses and transports each card, with no one touching the card. The present invention also relates to such a card game machine and a card reversing method. Each card placed on a card placement unit of a table is pulled by the magnetic force of a magnetic circuit having three electromagnet units. Accordingly, when a slider that supports the magnetic circuit is moved by a card transportation mechanism, the card slides on the upper surface of the card placement unit as if to follow the movement of the magnetic circuit. With one end portion of the card being attracted to the center electromagnet unit, the card is reversed by 180 degrees by the repulsive force generated between the other end portion of the card and the left-side electromagnet unit.

  • Patent number: 6411294
    Abstract: The image display apparatus of the present invention examines the transparency of a pixel to determine whether the Z coordinate of the pixel should be written in the depth buffer. Therefore, when the objects which are constituted by polygons, wherein opaque pixels and translucent pixels coexist, intersect each other, the variation in the display of image patterns which are to be displayed is increased. Since the writing control is performed under simple conditions, i.e., in accordance with the transparency of a pixel, an image closer to the ideal one can be selected without substantially increasing the load imposed on the rendering circuit.
