摘要 |
<p>A system for expanding color gamut includes: a signal input unit configured to input color information of pixels; a forward transform unit configured to transform the color information of pixels to L, a and b values in a linear Lab color space; a color gamut expansion unit configured to receive a color gamut expansion coefficient, expands L, a and b values provided by the forward transform unit to new L, a and b values in the linear Lab color space according to the color gamut expansion coefficients; a reverse transform unit configured to transform the expanded L, a and b values to color information of pixels in a large color gamut; and a signal output unit configured to output the color information of pixels in the large color gamut. A corresponding method for expanding color gamut is provided.</p> |
