Video image display apparatus and method

A video image display apparatus, for receiving a video signal and displaying a video image onto a display apparatus, comprising:

• first detecting means for detecting a skin color component of said video signal;
• second detecting means for detecting color components other than said skin color component of said video signal;
• color component control means for controlling gains for the color components of said video signal on the basis of a detection result of said first detecting means and a detection result of said second detecting means;
• and
• matrix means for outputting three primary color signals on the basis of said video signal,
• said first detecting means comprising:
• means for normalizing each of said three primary color signals outputted from said matrix means by a predetermined ratio;
• and
• means for outputting a lowest signal level as said skin color component among said normalized three primary color signals.
