A Single-Vidicon Television Camera System
The means of converting a scene to be televised to a color video signal usable in either CCTV or broadcast facilities is described. The optical system for both “live” and “film” reproduction is discussed including the striped filters, the objective lens and the field lens requirements. There are unusual requirements for the deflection and electrical potentials on the pickup tube; the need for and means of accomplishment of deflection linearity, uniformity of resolution and lack of size and centering change are discussed. The SNR of the system must be very good to provide satisfactory results. The output from the camera has luminance information as well as color information on subcarriers, which must be handled in the normal video pass-band and processed to provide NTSC-compatible or NTSC signals. The option of providing internal sync signals to provide a completely self-contained system (except for power) is described.
