ABSTRACT:
A television signal recording/reproducing apparatus of the color-under recording type wherein an input composite video signal is separated into a luminance signal and a color signal. For the separated luminance signal, calculation of the interframe signals is executed so that the color signal component remaining in the separated luminance signal is removed by a frame comb filter. And the input signal and the output signal of the frame comb filter are mixed with each other. For the separated color signal, calculation of the interframe signals is executed so that the luminance signal component remaining in the separated color signal is removed by a frame comb filter. And the input signal and the output signal of the frame comb filter are mixed with each other. Each of the signal mixing ratios is controlled in accordance with the interframe level difference in the luminance signal. And the mixed signals are recorded on a recording medium after predetermined recording processes. Mutual interference between the luminance signal and the color signal is eliminated to consequently prevent deterioration of the signal-to-noise ratio while achieving a high image quality.
