ABSTRACT:
A signal processing system is disclosed in which the image resolution is improved by extending the horizontal frequency bands of separated luminance and chrominance signals and compensating the contour of an input image signal, the frequency band of the input chrominance signal is extended by the chrominance signal processing part, and by the extension of frequency band, the transition time of the high frequency components of the image signal is reduced for the high frequency image signal processing and reducing the short data processing time.
