IMAGE COMPOSITION DEVICE AND PROGRAM FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an image composition device which can generate a composite image having natural perspective.SOLUTION: An image composition device 70 includes: background spherical body generating means 71 which generates a background spherical body where a background is drawn from a background decompressed image according to a coordinate transformation rule; radius setting means 72 setting a radius of the background spherical body; background spherical body arranging means 73 which arranges the background spherical body in a virtual CG space in the way that a center of the background spherical body with the radius set is positioned at an original point in the virtual CG space; foreground extraction means 74 which extracts a foreground from a photographed image; and image composing means 75 which places the foreground at the original point in the virtual CG space, sets a posture and a focal distance of a virtual camera located in the virtual CG space, and generates the composite image to be photographed by the virtual camera.SELECTED DRAWING: Figure 3
