  • Patent number: 9007399
    Abstract: In an information processing apparatus, a virtual object shape storage unit acquires the position of an operation unit, sets a virtual plane at the acquired position in the virtual space, and records the trajectory of the operation unit after the virtual plane is set. The virtual object shape storage unit then obtains a projection trajectory by projecting the trajectory onto the virtual plane, and records the obtained projection trajectory as contour data representing the contour of a target virtual object on the virtual plane. And then, the apparatus acquires a position and orientation of a viewpoint of the user, and generates and outputs an image of the virtual space seen from the viewpoint on the basis of the acquired position and orientation, the virtual space including the virtual plane and the virtual object having the contour represented by the contour data.

  • Patent number: 8994729
    Abstract: An image processing apparatus comprises a simulation unit which performs a simulation of operation of an object and a display unit which generates based on a result of the simulation an image in which a virtual object is operating and displays the image. The apparatus further comprises a calculating unit which calculates a position and orientation of a predetermined part of an observer who observes the virtual object being displayed, and a generating unit which generates a parameter for use in the simulation based on the position and orientation of the predetermined part of the observer and the position and orientation of the virtual object. This structure makes it possible to set parameters of simulation in a virtual-reality or mixed-reality space through manipulation performed by the observer.

  • Patent number: 8249393
    Abstract: An index detection unit (1040) detects the coordinate values of indices in a sensed image sensed by an image sensing device (1020) attached with an orientation sensor (1010). A contribution degree calculation unit (1070) acquires contribution degrees according to a frequency at which the image sensing device (1020) is located to have an orientation indicated by orientation information included in the position and orientation information of the image sensing device (1020) at the time of image sensing. A data management unit (1060) generates sets of the coordinate values and orientation information measured by the orientation sensor (1010) at the time of sensing of the sensed image for respective indices. A calibration information calculation unit (1090) calculates an orientation of the orientation sensor (1010) with respect to the image sensing device (1020) using the position and orientation information, parameter values, and the sets generated for the respective indices.

  • Patent number: 7561212
    Abstract: A factor in deterioration of receiving characteristics of an antenna is automatically determined and automatically improved. In an apparatus for receiving digital broadcast signal, when receiving the signal, a received signal sent from the antenna 1 is orthogonally detected to a baseband signal; an average value of amplitude in radial direction of signal points of phase mapping of the baseband signal is then measured to calculate a C/N value for the received signal; an average value of amplitude in circumferential direction of signal points of the phase mapping of the baseband signal is measured to calculate an amount of phase noise of the received signal; a bit-error rate of transport stream that is given by demodulating the baseband signal is then measured; a factor in deterioration for receiving characteristics of the antenna is determined based on these results; and a desired measure mode is set based on the determination result thereof.

  • Patent number: 6633873
    Abstract: When a predetermined number of pieces of data are retrieved, a retrieving process is performed first on a local database 7 in a LAN 1, and a response counter 8 counts the number of pieces of response data accumulated in a response accumulation device 9. When it is determined that the predetermined number of pieces of response data cannot be obtained from the local database, a remote database 3 is searched by a retrieval device 6 through a communications device 2. Therefore, requests to search unnecessary databases can be reduced, and the load on a network and the remote database 3 can also be reduced successfully.
