Abstract
A karaoke apparatus has an information source for providing a performance data containing musical tone designation information, lyric indication information and fading control information according to progression of a karaoke song in response to a request. A tone generator operates according to the musical tone designation information for generating musical tones of the karaoke song. A first signal generator operates according to the lyric indication information for generating a lyric image signal indicative of lyric words of the karaoke song. A second signal generator generates a background image signal representative of a background scene of the karaoke song. A video superimposer operates according to the fading control information for mixing the lyric image signal and the background image signal with each other to synthesize a composite image signal such that a mixing ratio of the lyric image signal and the background image signal is time-variably controlled according to the fading control information during the course of the progression of the karaoke song. A display device operates according to the composite image signal for displaying a mixture of the lyric words and the background scene in either of fade-in and fade-out manners relative to each other during the course of the progression of the karaoke song.
