System and method for maintaining hue constancy
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.
