The invention relates to a projection system using multiple light sources ( 1 ) at the same time. The projection system ( 100 ) comprises multiple light sources ( 1 ), a lens array system for each of the light sources ( 1 ), a condenser lens ( 2 ), an aperture means ( 3 ), a light valve assembly and a projection lens ( 5 ) to project an image. The light sources are adapted to each simultaneously illuminate the whole light valve assembly. In one aspect, the invention relates to a system and methods for allowing separately control of brightness, contrast, dichroic color shift or beam uniformity. This controlling or adjustment is performed by controlling and/or adjusting the cross-section of the illumination beam of each of the multiple light sources near the aperture of the aperture means.
