A Plumbicon Color Broadcast Camera
New color cameras have been designed for optimum use of the Plumbicon tube which is now standard and in production. Research is proceeding toward higher resolution tubes with a broader spectral response and even greater sensitivity. The camera has zoom servoed optics, a novel beamsplit prism block, transistor circuitry, small dimensions and low power consumption. The long linear transfer characteristic of the Plumbicon and the absence of shading enable excellent color balance to be obtained over very wide levels of scene illumination and reflectance factors. Broadcast-quality pictures are obtainable at 150-ft-c incident illumination at f/4 (equivalent to depth of field of f/8 for the image orthicon), while color performance holds below 25 ft-c.
