Claim One:
1. An arrangement for projecting a multi-color image onto a projection surface ( 10 ), said arrangement comprising at least two image-generating elements ( 5, 6, 7 ) which are controllable using a control unit ( 8 ) and which enable generation of one partial color image each of the multi-color image, and a color combiner ( 4 ) arranged following the image-generating elements ( 5, 6, 7 ), wherein the light for the corresponding partial color image coming from the image-generating elements ( 5, 6, 7 ) is guided, in one partial beam path each, to the color combiner ( 4 ), which superimposes the light guided in the partial beam paths and emits it as a common beam, said arrangement further comprising projection optics ( 9 ) arranged following the color combiner ( 4 ), on which projection optics ( 9 ) the common beam impinges and which project the multi-color image onto the projection surface ( 10 ), and the image scales given by said arrangement being different for two or more partial color images, characterized in that one optical device ( 18 ) each is arranged in one or more of the partial beam paths of the partial color images whose image scales differ and each of said optical devices ( 18 ) 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 said partial color image corresponds to a predetermined, common image scale.
