  • Picture generating apparatus
    Patent number: 6718058
    Abstract: When a car turns, a visual point position CP and a sight line direction T are moved (from CP′ to CP and from T′ to T) in accordance with a turning angle of the car, and a displacement u of the visual point position (CP″) is made different from a displacement v of the sight line direction (T″). A ratio of the visual point position displacement u to the sight line direction displacement v is about 1:5.
    Type: Grant
    Filed: August 15, 2002
    Date of Patent: April 6, 2004
    Assignee: Kabushiki Kaisha Sega Enterprises
    Inventors: Ryuji Ochi, Takeshi Yamazaki, Hisaki Nimiya, Masayuki Ao, Katsu Oshida, Yasuhiro Hayashida, Taishi Yasuda

  • Image processing
    Patent number: 6483939
    Abstract: A picture processing apparatus having a shape memory with shape data of an object previously stored therein, a processor to set a coordinate value of an object in a three-dimensional virtual space of the basis of the shape date stored in the shape memory, a transformation device to receive the coordinate value set by the processor and transform the coordinate value into a visual field coordinate system based on a specified visual point, and a visual point setting device to move the visual point position from a predetermined standard position for a predetermined base object as defined in the three-dimensional virtual space on the basis of data of the base object as well as changes in the situation caused by the movement of the base object, and for sending a new position after the movement to the transformation device.
