    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.

    Abstract: System and method for maintaining perceived hue constancy. A method for displaying an image includes receiving a color vector and associated image data, remapping the color vector to maintain a perceived hue constancy by adjusting a hue component of the color vector in response to a change in a lightness component or a chroma component of the color vector, providing the remapped color vector to a light source for display, and displaying image data associated with the color vector. The use of the constant hue curve ensures that the adjusting of the color vector maintains the perceived hue of the color vector, thereby helping to maintain image quality.

    Abstract: A method for sending IP packets from a base station to a mobile station during transition of the mobile station from a dormant state to an active state is provided. The method includes receiving a lagging feature request from the mobile station. A physical layer of a traffic channel is established between the base station and the mobile station. A network layer of the traffic channel is established between the base station and the mobile station. After the physical layer of the traffic channel is established and while the network layer of the traffic channel is being established, the IP packets are packaged and sent to the mobile station in a particular format.

    Abstract: System and method for generating multiprimary signals with optimization for bit depth for use in display devices. A preferred embodiment comprises converting an input color signal into an output color signal, wherein the number of colors in the output color signal is less than a number of colors used in a display system, when a weighting of the input color signal is less than a specified threshold, and converting the input color signal into an output color signal, wherein the number of colors in the output color signal is equal to the number of colors used in the display system, when the weighting of the input color signal is greater than the specified threshold. The use of fewer colors eliminates low bit depth colors, allowing increased dither quality in dimmer images.
