Abstract
Abstract An apparatus and method for improving image quality and in particular to an apparatus and method for converting binary images to grey-scale or color images and displaying those images. The apparatus and method utilize the natural process of integration which occurs when a person views images at sufficiently high rates and involves identifying least significant subframes within a group of subframes and reducing the intensity of those subframes or extending the duration of subframes other than the least significant subframes.
