    • 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.
    • 本发明涉及用于全息图像显示系统的改进技术的方法,装置和计算机程序代码。 一种与由相位掩模数据表示的相位掩模(25)光学接触的像素化全息图显示装置(24)的数据生成方法,用于产生全息图像,该方法包括:输入所述全息图像的图像数据(102) ; 对从所述图像数据导出的数据执行全息变换(100)以产生所述全息图显示装置(24)的全息图数据(m),使用所述相位掩模数据来调整所述全息图显示装置的相应区域的所述全息图数据和所述 相位掩模 以及量化所述全息图数据(m)以产生用所述相位掩模(25)在所述全息图显示装置(24)上显示的量化像素数据(104),以产生所述全息图像(14)。 其中对所述全息图显示装置的像素连续执行所述量化; 并且其中所述方法还包括:确定由所述量化产生的所述全息图显示装置的像素的所述数据的误差,并且在量化所述全息图数据之前使用所述误差数据来补偿所述全息图数据(mc),以产生量化像素数据, 所述全息图显示装置的另一像素。
