The sharpness of a digital image is enhanced by an edge enhancement process in which the edge adjustment range is adjusted. The image processing apparatus of the present invention determines the edge enhancement range by calculation using a weighting matrix. Specifically, data of a target pixel and the surrounding pixels are calculated using a weighting matrix selected by a weighting selection means, and the edge enhancement range is determined by comparing this calculated value to a specific threshold value. The data of pixels within the enhancement range are then subjected to the edge enhancement process. |
