Abstract

The luminance detail rendition, obtained from a color television signal in which the high-frequency components of the luminance signal are formed in the same way as the lows, is not correct in two respects: (1) The luminance transition amplitude is nearly always reproduced with incorrect amplitude, and (2) the transition is in a dark surround. This paper explains the cause of these two defects and derives an expression for a luminance signal which is free of these defects, and which may be transmitted within the present FCC standards.
