ABSTRACT:
A method for enhancing the sharpness of a color image includes the steps of generating three color separation signals and selecting one of the color separation signals to be a sharp signal; generating an unsharp signal from a color image and then multiplying the difference between the sharp signal and the unsharp signal by three multiplier coefficients to form three sharpness-enhancement signals. The resultant signals are added to the corresponding color separation signals to form sharpness enhanced color separation signals representing a sharpness enhanced color image.
