Abstract
A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color. A data signal on a pattern of odd and even scan lines in the pattern is synchronized with movement of a scan mirror operative to sweep a light beam along each scan line to align all the scan lines.
