Sharpening a digital image in accordance with magnification values

A method of processing a digital image having pixels to improve the sharpness of a print generated from the digital image comprising:

• a) determining a magnification value representing the magnification of a pixel of the digital image on the print based on the number of input digital image pixels and the output number of digital image pixels;
• b) producing a lowpass filter in response to the magnification value;
• c) using metadata associated with the digital image to produce a gain value;
• d) using the lowpass filter and the gain value to operate on the digital image to adjust the sharpness of the digital image to produce a sharpened digital image;
• e) resizing according to the magnification value the sharpened digital image to produce a resized sharpened digital image which includes the output number of digital image pixels;
• and
• f) producing the print based on the resized sharpened digital image.
