Abstract
A system for adjusting color image quality includes converting color video signal sources into component video signals including a luminance signal and chrominance signals. A signal axis rotation circuit performs coordination transformation on the chrominance signals in accordance with a hue calibration parameter; and a multiplier multiplies the coordinate-transformed chrominance signals with a chroma calibration parameter to obtain output chrominance signals. The output chrominance signals and the luminance signal together form a component chrominance signal, which is applied to and output by a chrominance signal inverse conversion unit.
