Claim 18:
19. A method of displaying a first holographic reconstruction and a second holographic reconstruction, the method comprising:
receiving an image for projection, wherein the image comprises a first colour component and a second colour component;
obtaining a displacement map, comprising a plurality of displacement values, the displacement map being a map of displacement of the second holographic reconstruction with respect to the first holographic reconstruction on a replay plane;
pre-processing the second colour component of the image in accordance with the displacement map to distort the second colour component of the image, and then
calculating a hologram of the first colour component and a hologram of the distorted second colour component;
forming the first holographic reconstruction on the replay plane by displaying the hologram of the first colour component on the first spatial light modulator and illuminating with light of the first colour; and
forming the second holographic reconstruction on the replay plane by displaying the hologram of the pre-processed second colour component on the second spatial light modulator and illuminating with light of the second colour.
