Abstract: The transfer characteristics of telecine chains must be standardized if the quality of television pictures derived from film is to be improved. The level on which to standardize the light transfer characteristics of telecine for optimum results has been established. Experiments have shown that the overall television system should have an average gradient of 1.50.* Measurements on live camera chains confirm this finding. Upon applying measurements of film system transfer characteristics, we concluded that the telecine should have a gamma of 0.40, except at the black end of the curve where flare light in the telecine projector requires a higher gamma. Systems that have the optimum characteristics are in commercial use, but other systems in use have characteristics greatly different from the optimum.
