PROBLEM TO BE SOLVED: To reproduce the three-dimensional shape of an object without increasing scale of a device. SOLUTION: When a video recording medium 18 is loaded on an information reproducing device 205, reproduction of the video recording medium 18 is started, a video signal, a position signal, a posture signal and a control signal which are written in the video recording medium 18 are extracted and supplied to a calculating device 206 by the information reproducing device 205. The three- dimensional shape of the object 201 is calculated based on the supplied video signal, position signal, posture signal and control signal by the calculating device 206. In addition, computer graphics data is generated from the calculated three- dimensional shape and is displayed on a display 207 by the calculating device 206.
