  • METHOD FOR CHANGING AN IMAGE DATA SIGNAL, DEVICE FOR CHANGING AN IMAGE DATA SIGNAL, DISPLAY DEVICE
    Publication number: 20110317918
    Abstract: In a method for color enhancement the color distance between spatially close colored pixel or pixel areas does not change more than a threshold, the threshold being a function of the initial color distance. The color difference between pixels that are close together and did not differ much in color will be restricted. This reduces the change on unnatural looking parts of an image and allows more pronounced color enhancement to be 5 used.
