Abstract:
An autostereoscopic display apparatus comprising N image sources coupled with a matrix display panel having an array of display elements which are arranged so as to extend in rows and columns in a row and column direction respectively and in groups with each group comprising N adjacent display elements in the row direction, with each of said N display elements being driven by a respective one of said N image sources, where N is a number greater than two, and optical director means comprising a plurality of optical director elements each of which is associated with a respective group of display elements for directing the outputs of the display elements in mutually different angular directions, characterised in that each of at least two of the N image sources comprises an image rendering apparatus having a host processor with associated main memory for the storage of object primitive data and a first display processor with associated display memory, the host processor comprising means for supplying object primitive data to the first display processor, and the first display processor comprising means for generating from the object primitive data a series of pixel values and pixel addresses for application to the display memory; and in that at least one of the N image sources comprises a post-processing stage coupled with one of the said image rendering apparatuses and arranged to apply a horizontal shift to pixel values of images generated thereby.
