Abstract
PURPOSE:To reproduce a high quality picture, by adding a luminance signal component relating to a transmission band to a chrominance signal, to a luminance signal of a color television signal as a detail compensation signal. CONSTITUTION:Each primary color signal form color television cameras 0, 1, 2 is picked up with a Y signal to be Y=0.3OR+0.59G+0.11B at a matrix circuit 11 which makes the same operation as a matrix circuit 6, and (Y)1/gamma is obtained by non-linear compensation with a gamma compensation circuit 12. A signal component of (Y1/gamma-Y') is picked up by making subtraction for the (Y)1/gamma signal from a Y' at the output of a matrix circuit 6 at a mixer 13. Further, components more than the cut-off frequency of low pass filters 7, 8 are picked up from a high pass filter 14 to obtain (Y1/gamma-Y')H, and it is added with the Y' signal of the matrix circuit 6 from a mixer 15.
