Ghosting on electrophoretic displays is an image artifact where previously displayed image content is visible in the current image. This paper introduces use of the previous image in a digital halftoning method to dither ghosting errors from grayscale imagery. Experiments show this method eliminates ghosting artifacts providing quality images without hardware modification.
