  • Publication number: 20070003162
    Abstract: The image generation device includes distance calculation means for calculating a distance between a space model and an imaging device arrangement object model which is a model such as a vehicle having a camera mounted, according to viewpoint conversion image data generated by viewpoint conversion means, captured image data representing captured image, a space model, or mapped space data. When displaying an image viewed from an arbitrary virtual viewpoint in the 3D space, the image display format is changed according to the distance calculated by the distance calculation means. When displaying a monitoring object such as a vicinity of a vehicle, a shop, a house or a city as an image viewed from an arbitrary virtual viewpoint in the 3D space, it is possible to display the monitoring object in such a manner that the relationship between the vehicle and the image of the monitoring object can be understood intuitionally.

  • Publication number: 20070002015
    Abstract: A movement detection device includes a self-sustaining movement detection unit which is attached to an operator's body and detects a movement or a posture of an attached part of the operator's body. An image pickup section picks up a projected image from an optical system which simultaneously inputs a peripheral image. An image conversion section converts an all azimuth image picked up by the image pickup section into a cylindrical panorama image. An image recognition section includes cylindrical panorama images at different times. A camera posture estimation section acquires movement information of the image pickup section based on a comparison result of the image recognition section. A space sensor posture estimation section acquires a position/posture of the attached part in a space based on information of the self-sustaining movement detection unit and the camera posture estimation section.

  • Patent number: 7062250
    Abstract: In a cellular video telephone having a built-in battery, the remaining electric power of the battery is detected. The data communication speed and the display of image on a display are variably controlled based on the detected remaining battery power, that is, the communication speed is lowered and the display is turned off, as the remaining power decreases. Alternatively or in addition, the communication speed and the image display are controlled variably based on availability of external power source in the course of voice and image communication.
