  • Patent number: 6086380
    Abstract: In a self-operated karaoke recording booth a user is provided with a selection of background scenes from which to choose and also with the option of having the lyrics of the karaoke selection displayed or suppressed. A video camera positioned at the user's eye level is located on the nonreflective side of a one-way mirror and is directed at a specified performer location through the one-way mirror, which is inclined at a forty-five degree angle relative thereto. Messages and video displays are provided to the user by a video display monitor connected to a computer that faces the reflective side of the one-way mirror and is also located at a forty-five degree angle relative thereto. The system is designed to maintain the visual focus of the performer directly into the lens of the video camera throughout the performance and to combine the video camera images with the background scene in such a way as to avoid a double exposure or phantom image of the performer against the background.
