A CODEC compresses and encodes a motion picture captured at a high speed of 240 fps frame rate in MPEG format. The CODEC divides pictures in each frame into I pictures and the main frame P pictures and the other sub frame P pictures. In encoding P pictures of the main frame, the CODEC uses I pictures that are adjacent on the time axis or P pictures of other main frames as a reference picture. With a playback device, etc., of its motion picture playback performance of 60 fps, to perform an actual speed playback with the playback time being equal to the picture-capturing time, only the main frame alone is to be subjected to playback, in that case the decoding process of P pictures of the sub frames is not required.
