摘要

PROBLEM TO BE SOLVED: To provide a virtual studio video creation apparatus and method, and a program therefor in which natural composited video is realized in real time more easily than three-dimensional CG without sense of incompatibility, and photographing is made possible only by moving a studio set at a minimum.;SOLUTION: A virtual studio video creation apparatus A which uses a whole-sky image Zg created based upon camera data and differential information is provided with: a camera data collecting part 8 for collecting studio camera data associated with a principal point position of a lens of a studio photographing camera 6 such as panning to a photographing site set Gs; a lens distortion calculating part 9a for calculating a lens distortion based upon the studio camera data and the camera data; a lens distortion correction corresponding image creating part 9b for creating an electronic image Eg for display by projecting and converting the whole-sky image based upon the lens distortion; and a video compositing part 11 for compositing the electronic image and a studio image Sg into virtual studio video Vp based upon the differential information.;COPYRIGHT: (C)2004,JPO
