Abstract
There is disclosed a system for enhancing resolution of a xerographic process by submodulation of each individual pixel. The submodulation is achieved by anamorphically reducing the square pixel presentation of light rays to a rectangle having a number of controllable segments within each square pixel scan line. By controlling the presentation of light rays to selected segments within each pixel gray scale an enhanced resolution can be achieved.
