Abstract

A video signal in component form is processed by generating high frequency linear color component signals from wideband linear color component input signals. The high frequency linear color component signals are combined to produce a high frequency linear luminance component signal, which is combined with color component signals that contain low frequency components present in the wideband linear color component input signals to produce high-frequency-corrected linear color component signals.
