  • Patent number: 7558403
    Abstract: A configuration for measuring the position and the orientation specific to a mixed reality is separated from an application 70 to operate independently, and a shared memory 60 or process-to-process communication is used for data communication between them. This allows to modify configuration associated with the measurement of the position and the orientation such as the type of the sensor or an alignment method without modifying or recompiling the application 70. This facilitates providing the mixed reality system and supporting system modification.

  • Patent number: 7365706
    Abstract: An image composition system includes an HMD (100) having a right-eye camera (110), a left-eye camera (111), a right-eye LCD (130) and a left-eye LCD (131) for displaying a real image, and the like, and an information processing apparatus (300) for generating another image different from the real image. A composite image obtained by superimposing the other image generated by the information processing apparatus (300) on the real image captured by the right-eye camera (110) and left-eye camera (111) is displayed on the right-eye LCD (130) and left-eye LCD (131). The display region of the other image is determined based on the position and posture of the head of the user who wears the HMD (100). The user can observe the other image superimposed on the real image at an appropriate position while wearing the HMD on his or her head.

  • Publication number: 20040109009
    Abstract: A graphic card (130) renders a virtual space image on a memory (122) according to the position and orientation of a video camera (140) using data indicating the state of a virtual space, 3DCG data loaded from an HDD (123) onto the memory (122), and data indicating the position and orientation of the video camera (140). A real space image captured by the video camera (140) is then acquired. The graphic card (130) superimposes the acquired real space image on the virtual space image rendered on the memory (122) to generate a mixed reality space image on the memory (122), and then outputs the mixed reality space image to a monitor (150). Upon depression of a shutter (160), the mixed reality space image rendered on the memory (122) at that time is output to a printer (170), which prints the mixed reality space image on a print medium such as a paper sheet, OHP film, or the like.

  • Patent number: 6741276
    Abstract: In a camera control system, a video sending terminal sends video from a video camera through a network to client terminals. The video camera is controlled by control commands from a client terminal which has been issued control from the video sending terminal in response to a request for control by the client terminal. The client terminal currently controlling the video camera is notified of a new request for control of the video camera made by another client terminal so that client terminals are notified of the locality of the video camera control.
