ABSTRACT:
With respect to a stacked three-dimensional image, a point of view and a first projection plane are set, a central projection image is obtained according to a central projection method, and this image is shaded to obtain a first pseudo-three-dimensional image as if the image was observed under an endoscope. Then, a second projection plane is set with a positional relation so as to be perpendicular to the first projection plane and a second pseudo-three-dimensional image is obtained by projecting the same stacked three-dimensional image according to a parallel projection method and performing shading. An updated position of a new view point is obtained by using the second pseudo-three-dimensional image.
