June 19, 1995 Due to the many questions I have recieved on my recent note, please be advised that my company's continuous-tone, gray-scale masking is EXACTLY what I stated. It is NOT binary or half-tone, every single pixel has an actual shade of gray. Such a shaded pixel must be at least 1 um square, but can in fact be larger in steps of 1/4 um. We had an article in IEEE Spectrum (Oct 1993, p 68, "The finbest gray scale yet") about our work. Regards, Steven Morton Oxford Computer, Inc. Oxford, CT USA
