Abstract
A color gamut expansion method and a display device where the color gamut expansion method is applied are provided, realizing appropriate color reproduction compared with the prior. The color gamut expansion method includes the steps of: acquiring a subjective evaluation result signal inputted through user operation; and adjusting magnitude of chroma enhancement and magnitude of brightness contrast enhancement, of an input video signal, independently from each other, based on the subjective evaluation result signal, thereby performing a signal processing to expand a color gamut of the input video signal.
Claims6
A color gamut expansion method comprising steps of:
- acquiring a subjective evaluation result signal inputted through user operation;
- and
- adjusting magnitude of chroma enhancement and magnitude of brightness contrast enhancement, of an input video signal, independently from each other, based on the subjective evaluation result signal, thereby performing a signal processing to expand a color gamut of the input video signal.
A display device, comprising:
- an input section acquiring a subjective evaluation result signal inputted through user operation;
- a signal processing section adjusting magnitude of chroma enhancement and magnitude of brightness contrast enhancement, of an input video signal, independently from each other, based on the subjective evaluation result signal, thereby performing a signal processing to expand a color gamut of the input video signal;
- and
- a display section performing video display based on a video signal subjected to the signal processing by the signal processing section.
