In a color television camera where the semiconductor array picture sensors for the three colors of a television signal have, for example, 420 points per line, so that the first order carrier frequency lies in the neighborhood of 8 MHz, corresponding picture points for the respective colors are offset by 1/3 of the picture point period for any one color. The green signal is used as a reference signal and the red and blue signals are separated into a high-frequency component and a component limited to a top frequency of 3 MHz. The higher frequency components of the red and blue signals are added to the green signal, so that the phase relations at the first order carrier frequency will tend to cancel, so that a wideband green component of greatly reduced high frequency interference and band limited red and blue components free of such interference are made available with very simple signal processing to improve the resolution of the television picture.
