Abstract
A luminance signal/chrominance signal separation apparatus is provided with a detector for detecting diagonal components of a luminance signal from a composite video signal, wide-band pass filters, and narrow-band pass filters, wherein band pass filters to be connected to a three-line chrominance separation circuit are selected according to the amount of diagonal components of the luminance signal, thereby reducing cross color and improving resolution.
