Abstract

This invention discloses an image processing method for image sharpness enhancement. Based on a spatial-masking phenomenon, this method calculates the maximum allowable adjustment value ΔL for the increasing or decreasing of intensity values at each pair of pixels in the given image. The calculation of ΔL depends on at least the intensity information of that pair of pixels. The value of ΔL is often set as 0.1*ΔH, where ΔH is the intensity difference between that pair of pixels.
