1. An arrangement for projecting an image, comprising: a) a plurality of image projection modules, each having a laser for emitting a laser beam and a scanner for sweeping a pattern of scan lines in space at a distance from the modules, each scan line having a number of pixels, each pattern being partly overlapped at an overlap region; and b) a controller operatively connected to each laser and each scanner, for causing selected pixels to be illuminated, and rendered visible, by each laser beam to produce the image from each pattern, the selected pixels in the overlap region being illuminated at a lesser intensity than selected pixels not in the overlap region.
