FIELD: physics.
SUBSTANCE: method is realised by controlling a projection system comprising several solid-state light sources (2, 3, 4) of different colour (12,13, 14) and at least one spatial light modulator (1) having an array of switchable elements. Said array is illuminated by at least one of said light sources (2, 3, 4) for several illumination periods and is addressed such that the light is time- and spatially modulated to project images onto a screen. In the present method said light sources (2, 3, 4) are controlled to emit light modulated in amplitude (15) and/or time (18) during said illumination periods of said array. With the present method an increased grey scale resolution of the projection system can be achieved.
EFFECT: possibility of projecting images with improved grey scale resolution.
