ABSTRACT:
An arrangement for projecting a multi-color image, including at least two image-generating elements which enable generation of one partial color image each of the multi-color image, and a color combiner which superimposes the light partial beam paths and emits it as a common beam. The arrangement further includes projection optics. The image scales being different for the partial color images, one optical device each is arranged in one or more of the partial beam paths of the partial color images whose image scales differ and each optical device is configured such that, due to the change in the image scale of the corresponding partial color image effected by it, the image scale of the partial color image corresponds to a predetermined, common image scale.
