Abstract

See full text

An image generator with a system to affix a flag for identifying high resolution pixel data in a signal of both high and low resolution pixel data, so that high resolution pixel data is divided readily for separate treatment in a high resolution frame buffer. The low resolution pixel data is connected to a low resolution frame buffer where it is treated with an occlusion mask in accordance with occlusion fractional coverage computed separately. The pixel data is combined again in a mixer before it is converted for visual display.
