Abstract
A method and system of image processing which utilizes masked video slices to show grey scale images on a bilevel output device. A plurality of video slices of an image are formed by a binary thresholding technique, with each slice displaying the image at different levels of intensity. The same number of video masks are also formed which each comprise a unique pattern of on and off pixels. Each of the video masks is ANDed with a corresponding one of the images slices to create a plurality of masked video slices. The masked video slices are combined to create a binary grey scale image of the original image that can be displayed on a bilevel output device.
