1. An image projection system comprising:

  • a first projector operative to project first modulated light onto a screen, the first projector comprising a first spatial light modulator;

    a second projector operative to project second modulated light onto the screen superposed with the first modulated light, the second projector comprising a light steering module;

    a controller operative to process image data comprising pixel values defining target illumination levels for a target image to be displayed and to generate control signals for the first spatial light modulator and the light steering modulator wherein the processing comprises splitting light output between the first and second projectors in such a manner that the second modulated light includes a portion of the light for each of the pixels of the image and the first modulated light makes up a majority of the light for those pixels of the image for which the target illumination level is less than a first threshold level.
