1. A method of displaying a high-resolution image, comprising:

  • receiving a high-resolution image frame representative of a high-resolution image;

    generating a low-resolution sub-frame for each projector of a multi-projector display system based on the high-resolution image frame, each low-resolution sub-frame comprising a plurality of pixels with each pixel having an intensity level, wherein each projector projects a maximum number of unique intensity levels;

    dithering the intensity levels of the pixels of each low-resolution sub-frame to one of the unique intensity levels of the associated projector differently for each projector to form a dithered low-resolution sub-frame such that the dithered low-resolution sub-frames, when simultaneously projected in an overlapping fashion, form a projected image representative of the high-resolution image and having a maximum number of unique projected intensity levels substantially equal to a sum of the maximum number of unique intensity levels of all the projectors.
