1. An image exhibiting method of exhibiting an image of mixed reality space, comprising:
- an acquisition step of acquiring a three-dimensional object corresponding to an observer image sensing unit, wherein the three-dimensional object indicates a three-dimensional shape of a visual-field area being sensed by the observer image sensing unit, and wherein positions of a front clipping surface and a rear clipping surface of the three-dimensional object with respect to a view point of the observer image sensing unit are determined based on an internal parameter of the observer image sensing unit;
a sensing step of sensing a real space by using an exhibiter image sensing unit;
a superimposing step of generating an image of mixed reality space by superimposing the three-dimensional object on an image of the real space obtained in said sensing step, based on position and orientation of the exhibiter image sensing unit; and
a display step of displaying the image of mixed reality space on a display unit.

Abstract
Image exhibiting method of exhibiting an image of mixed reality space is provided. A three-dimensional visual-field area of an observer in the mixed reality space is calculated, a virtual visual-field object representing the visual-field area is generated, and the virtual visual-field object is superimposed on the image of the mixed reality space to be exhibited.
