Patent ID: 7813587

Claim:
A method for shoot suppression in image detail enhancement, comprising: employing a processor for: selecting image details for enhancement, wherein the selected image details are represented by a detail signal that is a function of an image signal f and a filtered version of the image signal f, determining a shoot suppression factor s for the detail signal at each pixel position based on symmetric image characteristics of the pixels neighboring a current image pixel in order to substantially suppress shoot artifacts in the enhanced image details, the pixels neighboring the current pixel are on either side of the current image pixel; and applying the shoot suppression factor s to the detail signal, wherein the shoot suppressor factor s is determined according to the relation: s= 1−(1−min(1 ,K 1 α))*β, wherein K 1 is a constant, and K 1 ≦1, α is a symmetry factor and β is an intensity factor.
