A moving image playback apparatus plays back moving image data, and synchronously displays a thumbnail image sequence obtained from the moving image data. In this state, when a cursor used to designate a thumbnail image falls within a predetermined area including the display area of the thumbnail image, synchronous display of the thumbnail image sequence is interrupted. When a thumbnail image is designated by the cursor, the playback position jumps to a corresponding scene to start playback of the moving image, and synchronous display of the thumbnail image sequence is restarted. When the thumbnail image sequence has been scrolled in the time-axis direction, synchronous display of the thumbnail image sequence is interrupted, and an instruction interface used to instruct restart of synchronous display is provided. When the instruction interface is operated in this state, synchronous display of the thumbnail image sequence is restarted.
