Abstract

A method and apparatus for improving the display of objects on an interlaced raster-scan television are disclosed. The invention takes each data point that will appear as a pixel on the screen and makes it appear also at pixel locations displaced by one unit in each of two axes, individually or collectively if desired. The direction of displacement is uniform for any given picture. The additional appearance is not stored as part of the picture data, but instead is generated "on the fly" as part of reading the data and preparing it for presentation on the television screen.
