1. A visual point position control apparatus for controlling positions of the visual points of images picked up by first and second cameras, comprising:

  • a) first producing means, based on coordinates of picture elements of image pickup elements of the first camera and an image pickup angle of the first camera relative to an image of an object picked up, for producing a first model of a picked up plane of the image of the object in a three-dimensional coordinate system;

    b) second producing means, based on coordinates of picture elements of image pickup elements of the second camera and an image pickup angle of the second camera relative to an image of the object picked up, for producing a second model of a picked up plane of the image of the object in a three-dimensional coordinate system;

    c) first mapping means for mapping image data output from the first camera onto the first model produced by the first producing means;

    d) second mapping means for mapping image data output from the second camera onto the second model produced by the second producing means;

    e) moving means for computationally rotating and moving the first and second models onto which image data are mapped within an angle α

    , formed by the visual point positions of the first and second cameras in the three-dimensional coordinate system, by angles β and



    - β

    ), respectively; and

    f) mixing means for mixing the image data mapped onto the first model and the image data mapped onto the second model by a mixing ratio corresponding to the rotation angles β and



    - β

    ) of the first and second models.
