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 of scan lines to be illuminated to produce an image of high resolution in color. The direction of scanning of the scan lines is switched between alternate frames, and the resulting image is the superposition of successive frames integrated for viewing by the human eye.
