Abstract
The increased proportion of color TV broadcasting and the use of lead oxide camera tubes having linear transfer characteristics have called for increased attention to the use of proper gamma correction circuitry in the studio. Agreement on a limiting value of scene contrast ratio is helpful in order to achieve some degree of standardization in this area. A contrast ratio of 40 is suggested as a practical value.
