An image processing device includes an input device which receives image adjustment selections from an associated user interface device. Memory of the device stores a user interface generator, which generates a background adjustment selector for presenting to a user on the user interface device; a background adjustment component which, for each of a plurality of pixels of an input image computes adjusted color values, as a function of at least one of: (a) a background adjustment factor computed for the respective pixel, and (b) a background class derived from the computed background adjustment factor, the background adjustment factor being a function of a background strength of the pixel and a luminance strength of the pixel; and an image output component outputs an output image derived from the adjusted color values for the plurality of pixels. A processor implements the background adjustment component and image output component.
