Abstract
A karaoke apparatus is provided with a first storage for storing a plurality of karaoke data files corresponding to a plurality of karaoke songs and containing an accompaniment data and a picture index data, a second storage for storing a plurality of primary pictures, and a third storage for storing a plurality of secondary pictures which are mixed to the primary pictures. Upon requesting a desired karaoke song to select the corresponding karaoke data file, particular ones of the primary pictures and the secondary pictures are retrieved from the second and third storages according to the picture index data contained in the selected karaoke data file. A video mixer operates for mixing the retrieved secondary picture to the retrieved primary picture to synthesize a composite picture which meets a mood of the requested karaoke song. A tone generator operates according to the accompaniment data contained in the selected karaoke data file to sound an instrumental accompaniment of the requested karaoke song. A monitor displays the composite picture in synchronization with the instrumental accompaniment so as to present a background screen of the performed karaoke song.
