This invention relates to method, apparatus and computer program code for improved techniques for holographic image display systems. A method of generating data for a pixellated hologram display device (24) in optical contact with a phase mask (25) represented by phase mask data, for generating a holographic image, the method comprising: inputting image data (102) for said holographic image; performing a holographic transform (100) on data derived from said image data to generate hologram data (m) for said hologram display device (24), using said phase mask data to adjust said hologram data for corresponding regions of said hologram display device and said phase mask; and quantising said hologram data (m) to generate quantised pixel data (104) for display on said hologram display device (24) with said phase mask (25) to generate said holographic image (14); wherein said quantising is performed successively for pixels of said hologram display y device; and wherein the method further comprises: determining an error in said data for a pixel of said hologram display device resulting from said quantising and using said error data to compensate said hologram data (mc) prior to quantising said hologram data to generate quantised pixel data for a further pixel of said hologram display device. |
