Abstract

A tone correction system, method and interface is described in which a digital image is initially filtered (10) to obtain a corresponding locally averaged value for each pixel value of the image. The image is optimally filtered using a cone-type filter having a small filter radius and which favorably weights the center pixel values of the radius. Shadow and highlight values are obtained from selected shadow and highlight functions, respectively, using the locally averaged values (11). A tone function is derived from each of the shadow and highlight values for each pixel (12). Each pixel value of the image is then remapped (13) according to its derived shadow and highlight tone functions. The tone corrected image can be reinteratively corrected by adjusting parameters of the shadow and highlight functions and remapping the image data until a desired image quality is achieved (14, 15).
