' and confirming that the first playback time of '4 minutes and 15 seconds' of the first music 'Music 1' is shorter than the playback time of 'Reference Music 1', the first reference music, is shorter than '4 minutes and 30 seconds' By doing so, the 'rhythm game pattern 1' which is the first rhythm game pattern is displayed on the screen based on 'data 1' which is the data for the 'rhythm game pattern 1' which is the first rhythm game pattern, Only a partial pattern corresponding to '4 minutes and 15 seconds', which is the first playback time of the music 'Music 1', may be displayed on the screen.

At this time, according to an embodiment of the present invention, the pattern display processing unit 120 determines that the first reproduction time of the first music is longer than the reproduction time of the first reference music, After calculating a first difference time using the time difference between the first playback time and the playback time of the first reference music, the first rhythm game pattern is displayed on the screen based on the data for the first rhythm game pattern However, when the first music continues to be played in a situation where the display of the first rhythm game pattern is completed, the first rhythm game pattern is displayed again on the screen from the beginning to the portion corresponding to the first difference time. can

For example, the first music is referred to as 'Music 2', the first playback time matching the first music 'Music 2' is referred to as '3 minutes and 45 seconds', and the first reference music is referred to as 'Reference Music 2'. ', the playing time matching the first reference music 'reference music 2' is '3 minutes and 30 seconds', the first rhythm game pattern is called 'rhythm game pattern 2', and the first rhythm game Assume that the data for the pattern 'rhythm game pattern 2' is 'data 2'.

In this case, the pattern display processing unit 120 determines that '3 minutes 45 seconds, which is the first playback time of 'Music 2', which is the first music, is '3 minutes and 30 seconds,' which is the playback time of 'reference music 2', which is the first reference music. Since it is confirmed that it is longer than ', '3 minutes and 45 seconds' which is the first playback time of 'Music 2', which is the first music, and '3 minutes and 30 seconds', which is the playback time of 'reference music 2', which is the first reference music, is The first difference time may be calculated as '15 seconds' by using the time difference between them.

Thereafter, the pattern display processing unit 120 displays the first rhythm game pattern 'rhythm game pattern 2' on the screen based on 'data 2', which is data for the 'rhythm game pattern 2' that is the first rhythm game pattern. However, if the first music 'Music 2' continues to be played while the display of 'Rhythm Game Pattern 2', which is the first rhythm game pattern, is continuously played, the 'Rhythm Game Pattern 2' which is the first rhythm game pattern ' may be displayed again on the screen from the beginning to a portion corresponding to '15 seconds', which is the first difference time.

That is, the rhythm game device 110 may adjust the length at which the rhythm game pattern of the reference music is displayed according to the playback time of the music selected by the user.
