When the playback speed of a moving picture is changed to a slower playback speed during playback of the moving picture, the playback at the slower playback speed starts from the top of the range which includes, out of the moving picture being played back, the frames being played back when an instruction to change the playback speed was received and in which frames having the same recording frame rate as the frames are continuously recorded. Consequently, when the playback speed is changed during the playback of a moving picture, the scene for which the user wishes to change the playback speed can be played back reliably.
