<p><P>PROBLEM TO BE SOLVED: To provide a portable music game machine capable of reducing power consumed for discriminating the feature of music and suppressing the consumption of a power supply battery. <P>SOLUTION: In the music game machine comprising a signal processing part 10 for taking out and outputting signals correlated to the feature of the music from music reproducing signals, feature discrimination parts 30 and 31 for processing output signals from the signal processing part 10 at every prescribed sampling cycle Tm and discriminating the feature of the music on the basis of the processing result, and a game control part 32 for reflecting the discriminated result of the feature discrimination parts 30 and 31 on game content, the presence/absence of the output of the music reproducing signals from music reproducing equipment 100 is discriminated, and the power is supplied from the power supply battery 18 intermittently by a time length equal to or longer than the sampling cycle Tm each time at every prescribed power supply cycle Tp to the signal processing part 10 while the output is detected. When the music reproducing signals are not output, power supply from the power supply battery 18 to the signal processing part 10 is stopped. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
