Abstract

The invention relates to a system for generating a visual display signal comprising a substantially monochromatic scale signal. A visual display device (100) comprises a display processor (119) which comprises means for receiving a colour signal. The colour signal comprises a plurality of colour signal components, and specifically the signal may be an RGB signal. The display processor (119) further comprises means for weighting the colour signal components to generate weighted colour signal components, and means for generating a substantially monochromatic scale signal for reduced emission visual display in response to the weighted colour signal components. The scale signal may specifically be generated as 0.22 - R + 0.71. G + 0.07 - B . The scale signal is displayed on a display (105). The monochromatic scale signal is preferably a red monochromatic scale signal suitable for night time use and providing low visibility for unintended observers.
