Abstract
Provided is an apparatus for sharpening a blurred enlarged image, including a digital image output unit for outputting a digital image input through a digital image input unit. The apparatus includes a digital image processing unit for calculating a primary edge direction of the digital image input through the digital image unit to perform enlarging and edge sharpening on the input digital image. Accordingly, blurring is removed from the enlarged image without ringing or an artifact using an adaptive edge sharpening method, so that the enlarged image can be sharpened.
