Abstract (en)
[origin: DE19904372A1] The invention relates to an image representation system comprising a projector (1) for emitting projection light (4) so as to generate an image on a light-reflecting projection surface (7). According to the invention the wavelengths of the projection light (4) are situated in one or more discrete wavelength ranges in the visible spectrum and the projector-side of the projection surface (7) is covered with an optical filter (11) which is permeable only to light at wavelengths corresponding to those of the projection light (4).
