Vidicon Light-Transfer Characteristics and Film Reproduction
The light-transfer characteristics of the vidicon cannot be used directly to predict light-transfer characteristics of a television-film system. The practice of setting the darkest excursions of the video portion of a TV signal to black level, or cutoff of the TV picture tube, changes the effective light-transfer characteristic of the vidicon. Additional gamma correction of the electrical signal is required to reproduce film properly on television. The type of correction necessary for the proper reproduction of film meeting the new proposed specifications for density range and transfer characteristics of television film is described.
