PROBLEM TO BE SOLVED: To present a user with new pleasure of karaoke by compounding a 3D moving picture changing the visual point at random and a subject image extracted from a photography video image. SOLUTION: The moving picture generation system 10 included in a karaoke system 1 photoes a user U singing a karaoke musical piece by means of a camera instrument 11 and sends the video images sequentially to a chromakey device 20. A 3D moving picture generator 30 generates a 3D moving picture including the three-dimensional image of a back dancer. A 3D moving picture including a content of the position for viewing the back dancer changed at random is generated and sent to the chromakey device 20. The chromakey device 20 extracts the subject image of the user U from a photography moving picture sent from the camera instrument 11, compounds that subject image and the 3D moving picture sent from the 3D moving picture generator 30 to generate a compound image where the user appears in such a scene as the position for viewing the back dancer is switched at random.
