Abstract:
An image processing method comprising the steps of:applying sharpness enhancement to original image data to generate sharpness enhanced image data for a wholly sharpened image; performing edge detection on said original image data to determine edge intensity data for distinguishing an edge region of an object and the other region in an image; determining a blur retaining but sharpness enhancing coefficient for enhancing sharpness of the edge region of the object but retaining blur of the image in the other region of the edge region of the object based on the edge intensity data; subtracting said original image data from said sharpness enhanced image data to generate a sharpness enhancing component; multiplying the sharpness enhancing component by said blur retaining but sharpness enhancing coefficient to give a blur retaining but sharpness enhancing component; and adding the blur retaining but sharpness enhancing component to said original image data to generate processed image data for an image enhanced in the sharpness while retaining the blur.
