Abstract
Auxiliary figures superscribed on an original picture displayed on a display are moved and deformed conforming to a clue of a perspective view of an original picture so as to obtain a vanishing point automatically, and three-dimensional information of the original picture is estimated. Further, a camera angle is set up by moving and deforming an auxiliary figure for setting up three-dimensional information, and a picture at that camera angle is formed. It is possible to convert an original picture into a picture seen from a desired camera angle easily. It becomes possible, when a three-dimensional picture is formed, to convert a two-dimensional picture into a picture seen from another visual point on a computer without requiring a picture from the front and while maintaining the resolution of the perspective view as is with the perspective view as an original picture.
