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. The performer can choose to have the lyrics of the selected karaoke composition displayed or suppressed. If the election is for a display, the lyrics are displayed at the center of the viewing screen, directly in line with the video camera.

An automobile theft deterrent system for providing still video images and continuously recorded video images of activities within the automobile and scenes external to the automobile. The system has a front video camera mounted in the front portion of the automobile, preferably against the rear surface of the rearview mirror, and an overhead video camera mounted on the automobile interior top surface, preferably adjacent to the overhead light. The front video camera points in the forward direction to outside of the automobile. The overhead video camera points downwardly from behind the one way mirror surface of the rear view mirror to view activities within the automobile. The images from both cameras are transmitted to a hand-held receiver device held by the automobile owner. The receiver has a viewing screen which enables the owner to view the images from the camera.

A multi-direction image capture apparatus is useful for capturing images through either a primary aperture (125) or a secondary aperture (300) using only a single image sensor (205). The apparatus includes a housing (105) that includes the primary aperture (125) and the secondary aperture (300). An image sensor (205) is positioned in the housing (105) and has a light sensitive data capture surface (315) facing the primary aperture (125). A one-way mirror (130) faces the light sensitive data capture surface (315) of the image sensor (205). Thus light passing through the primary aperture (125) passes through the one-way mirror (130) and impacts the light sensitive data capture surface (315) of the image sensor (205), and light passing through the secondary aperture (300) is reflected off the one-way mirror (130) and impacts the light sensitive data capture surface (315) of the image sensor (205).
