Abstract
In a video signal processing circuit, an adaptive signal compression is realized by correcting the color saturation by multiplication of color difference signals (R-Y, G-Y) by a same correction factor in such a way that color signal values (R, G, B) remain below their respective maximally allowed values without the luminance (Y) being limited as well. Preferably, the correction factor is obtained in dependence upon a non-linearly compressed luminance signal (Y').
