In an image projector having at least one projection beam that is actuated in the raster mode and in the calligraphic mode for representing a raster component and a calligraphic component of a total image that is projected onto a display, to attain a higher image brightness and a sharper image contrast during projection in non-darkened rooms, the at least one projection beam is a laser beam (19) that is split into two linearly-polarized partial beams (21, 21'), with the two partial beams (21, 21') being subjected to a separate modulation and deflection such that the one partial beam (21') writes the raster component and the other partial beam writes the calligraphic component. The two partial beams (21, 21') are projected simultaneously onto the display; the partial beams may be optically superposed prior to being projected. |
