PROBLEM TO BE SOLVED: To reduce coordinate errors and to generate stable images no matter which spot of a space a view point is present at by transforming the coordinate of an affine coordinate system to an affine coordinate at a virtual view point position by a pinhole projection method and generating the image at the virtual view point position. SOLUTION: An image set A is photographed (50) and the reference vector of the affine coordinate is prepared (58). The image set B is photographed and the weak calibration of a camera is performed by using it (60). Scene photographing for generating an optional view point image is performed, the image set C is attained, correspondence between the images is obtained (62) by stereo matching by using the result of a processing 60, transformation to the affine coordinate is performed (64) and the affine coordinate of a virtual camera position is calculated (66) by a virtual camera parameter 56 stored beforehand. It is transformed (68) to a camera view and the image for which the virtual camera position is the view point is formed. Then, the virtual camera parameter 56 is changed and the image of an optional position is generated. |
