Abstract: Methods for gamut mapping and boosting a color saturation of a color signal having multiple colors and a color value for each color. An example method includes mapping each color from a first to a second color space, adjusting each color in the mapped color signal including boosting a color saturation; determining a maximum color value of the color signal; and, in response to a determining that the maximum color value exceeds a maximum displayable color value, setting the color value of the color having the maximum color value to be equal to the maximum displayable color value and scaling color values of colors not having the maximum color value.

Abstract: A system and method for gamut mapping out-of-gamut signals. A method includes adjusting each color in a color signal, determining a maximum color value of the color signal, in response to a determining that the maximum color value exceeds a maximum displayable color value, scaling color values of colors not having the maximum color value, and setting the color value of the color having the maximum color value to be equal to the maximum displayable color value. The method further includes leaving the color values of the colors in the color signal unchanged in response to a determining that the maximum color value does not exceed the maximum displayable color value. The scaling of color values not equal to the maximum color value results in a maintaining of a proper hue of the color signal, thereby not introducing color artifacts and other forms of color noise.
