1. An image processing method, for extracting high frequency components from digital photographic images, comprising the steps of: obtaining a blur width of a blur within a digital photographic image; obtaining a reduced image, by reducing the resolution of the digital photographic image to a reduced digital photographic image when the blur width is greater than or equal to a predetermined threshold value; maintaining a size of the digital photographic image by not reducing the digital photographic image if the blur width is less than a predetermined threshold value; extracting the high frequency components by employing the reduced digital photographic image or the non-reduced digital photographic image; and outputting a corrected digital photographic image based on the extracted high frequency components.
