ABSTRACT:
A system and method for sharpening a digital image (38) having one or more image parameters, for printing with one or more print parameters, and for viewing at one or more viewing parameters, the method comprising the steps of preparing sharpening radius information correlated in a correlation process with one or more print parameters, creating a first data storage device (192) for storing the sharpening radius information, receiving the one or more print parameters, determining an image sharpening radius for the digital image (38) from the sharpening radius information and the received one or more print parameters, and sharpening the digital image (38) using the image sharpening radius in a sharpening algorithm. A correlation process is described, a sharpening algorithm with foliage protection, hue protection, antialiasing protection, and noise reduction is disclosed, and a detail identification process is described.
