GENERATING METHOD FOR PROJECTION IMAGE OF VIDEO FACILITY

PROBLEM TO BE SOLVED: To reproduce infinite variations of video by analyzing images needed to generate a desired projection image and giving an indication for supplying them to a right-image supply means. SOLUTION: A direction device 1 inputs direction information consisting of the specification of an object to be projected and astronomical observation data of the observation position, observation date and time, etc., of the object. A control unit 2 analyzes images needed to generate a target projection image and a composing method for them from the direction information given as the astronomical data to the direction device 1, and also sends the indication for supplying them to the image supply means and an indication for putting the supplied projection images together to an image composition device 5. The image composition device 5 puts the images obtained from image generating devices 3 and 3 together by following a procedure indicated by the control unit 2. A projection device 6 is a video image projector which projects the image outputted by the image composition device 5 on a dome.
