PURPOSE:To extract modulation parameters of music from the music information of KARAOKE information (music information, text information, background image, etc.) and generate and display graphic data which change by the modulation parameters. CONSTITUTION:The KARAOKE device is equipped with a reader 3 which reads data out of a recording medium 2, a signal mixing amplifier 5 which mixes the music information outputted by the reader 3 with a voice signal inputted from a microphone 9 and drives a speaker 10, a music modulation extraction part 6 which extracts features (modualtion information) of the pitch and intensity of the music information, a modulation image generation part 7 which generates the graphic data corresponding to the value of the output signal of the music modulation extraction part 6, and a video output device 8 which sends the output of the modulation image generation part 7 to a display device 11. |
