Abstract

A method for image processing includes generating a pixel window of image data and determining whether the pixel window-is stable or unstable. Image enhancement values are then obtained from a look up table for stable windows when the window is stable, and image enhancement values are obtained from a look up table for unstable windows when the window is unstable. An enhanced target pixel value is then output according to the obtained look up table image enhancement value.
