PROBLEM TO BE SOLVED: To efficiently introduce a posted dynamic image to a user without causing the user to spend a time on a search or the like for a posted dynamic image, the time which the user could otherwise use for singing a karaoke musical piece.SOLUTION: A dynamic image reproduction device 1 acquires, about a musical piece played by a karaoke device 2, time information indicating a non-singing time slot corresponding to a song-less portion of the played musical piece. The dynamic image reproduction device 1 also selects, from among a plurality of posted dynamic images stored in a storage unit 11, a posted dynamic image conforming to a prescribed dynamic image extraction condition as a dynamic image to be reproduced. Then, the dynamic image reproduction device 1 determines a length of reproduction time and a reproduction timing necessary to reproduce the posted dynamic image to be reproduced in the non-singing time slot of the played musical piece. Next, the dynamic image reproduction device 1 reproduces the posted dynamic image to be reproduced according to the determined reproduction timetable when the non-singing time slot of the musical piece is played by the karaoke device 2. |
