ABSTRACT:
Disclosed is an image display technique for displaying a high-quality image by an image signal of appropriate color saturation. To this end, in the invention, color histogram information is detected from a color difference signal and average brightness information or brightness histogram information from a brightness signal. Based on the detected color histogram information and average brightness information or brightness histogram information, the demodulation axis of a color difference signal is adjusted, thereby controlling the color saturation (chroma) of an image. This enables display of an image having color intensity suited to the brightness and chroma of an image signal.
