ABSTRACT:
A system is provided for processing an image signal composed of a luminance signal having a second frequency band including a frequency component higher than a frequency component included in a first frequency band and a color signal having the frequency component included in the first frequency band. The luminance signal is separated into a first luminance signal having a frequency component not higher than the frequency component included in the first frequency band and a second luminance signal having a frequency component higher than the frequency component included in the first frequency band. A frequency converter converts the second luminance signal into the first frequency band to output a frequency-converted second luminance signal. A multiplexer multiplexes the input color signal with the second luminance signal to provide a multiplexed signal. A delay unit, having a pass-band for the passage of a signal having the first frequency band, delays the first luminance signal output and the multiplexed signal.
