Abstract: A target image 60 is multiplied by an appropriate phase pattern to provide a phase modified image 61 to which an inverse Fourier transform is applied to generate a source hologram 62. A set of intermediate holograms 63 are generated from the source hologram 62 using vertical and/or horizontal shifts of the source hologram 62. A set of final holograms 64 are generated from the set of intermediate holograms 63 using sum and/or differencing of various members of the set of intermediate holograms 63. Each final holograms 64 is approximated to form kinoforms 65 for sequential display to an observer 66 as illuminated subframes 67a to 67d. The observer 66 perceives only one image formed from a number of subframes 67a to 67d, wherein the noise associated with the kinoforms 65 averages over time and the observer 66 perceives an attenuation of such noise.
