摘要： The invention relates to method, computer program code and signal processing/ image display systems for displaying one or more images using holographic techniques. We describe a method of generating data for displaying an image defined by displayed image data using a plurality of holographically generated temporal sub frames, the temporal subframes being displayed sequentially in time such that they are perceived as a single noise-reduced image. The method comprises generating holographic data from the displayed image data for each sub frame of said set of subframes such that successive replay of holograms defined by said holographic data for said subframes gives the appearance of said image, and wherein the method further comprises, when generating said holographic data for a said subframe, compensating for noise in said displayed image arising from one or more previous subframes of said sequence of holographically generated subframes .
