Abstract:
Provided is a video signal generation apparatus and method that may minimize crosstalk between a luminance signal and color difference signals. The video signal generation apparatus may generate the luminance signal using a nonlinear Y signal and then generate color difference signals using a nonlinear XYZ signal to maximize a de-correlation characteristic between the luminance signal and the color difference signals.
