Abstract: A luminance signal is formed from a first luminance signal (Y1) produced by mixing a plurality of complementary color signals obtained from a television camera (2) having complementary color filters and from a second luminance signal (Y2) produced by mixing at a predetermined ratio a plurality of primary color signals that are derived from the plurality of complementary color signals, the first and second luminance signals (Y1, Y2) are then mixed so that the composite output signal (YL+H) forms the desired luminance signal.

Abstract: A dot sequential color signal which is generated in an image pick-up means, as for example a CCD type image sensor is supplied to a first sampling and hold (S/H) circuit, with the frequency of the sampling pulse used in the first S/H circuit being at a predetermined frequency (FO), and the output of the first S/H circuit is supplied to a second S/H circuit, with the frequency of the sampling pulse used in the second S/H circuit being selected to be N times of the predetermined frequency (NFo), so that the frequency of the sampling noise caused by the sampling operation is relatively high compared with the output signal of the image pick-up means, and thus the cut-off frequency of a low pass filter for eliminating the sampling noise can be selected to be high enough not to attenuate the desired signal.
