  • GAMUT MAPPING
    Publication number: 20100033494
    Abstract: A color mapping system comprises a detail detector (1) to generate a control signal (CS) which indicates local detail in an input image signal (IS). The system further comprises a color mapper (2) which maps a first image signal (FIS) into a mapped image signal (MIS) under control of the control signal (CS) for locally changing an intensity and/or a saturation of the first image signal (FIS) as a function of the local detail. The first image signal (FIS) is the input image signal (IS) or a low-pass filtered input image signal (LIS).
