1. A video camera means for use in a video system comprisinga video imaging means having an imaging surface for receiving an optical image thereon and for generating a video signal representing a said optical image;

  • a housing having an optical device coupling end enclosing and supporting said video imaging means and including means defining an opening in said optical device coupling end, said housing enclosing and supporting said video imaging means at distance from said opening which distance is determined by the space between the imaging surface and the optical device coupling end to pass a said optical image from an optical device operatively coupled to the housing, through the opening in the optical device coupling end and distance located between each opening and imaging surface onto the imaging surface;

    circuit means operatively coupled to said video imaging means and formed into a predetermined geometrical shape which defines a passageway adapted to pass a said optical image, said circuit means being positioned in said distance located between said opening and said imaging surface with said passageway positioned relative to the opening and said imaging surface to permit a said optical image to pass from said opening through said passageway and said distance located between said opening and imaging surface onto said imaging surface, said circuit means includingmeans responsive to said electrical video signal and for producing a preamplified electrical video signal therefrom having signal to noise ratio which is at least 40 decibels; and

    driving circuit means electrically connected to said preamplifying means and to an output circuit for applying a said amplified video signal having a signal to noise ratio of at least 40 decibels to said output circuit.
