Abstract: An apparatus is disclosed for controlling pixel addressing of a pixel display device to drive the display device as an N view autostereoscopic display. A graphics controller (40) generates multiple views of a scene from different viewpoints. The graphics controller (40) selectively accesses a combined image memory buffer (43), so that portions of each view are written by the graphics controller (40) to allocated areas of the combined image memory buffer (43). A display (54) is driven according to the data in the combined memory buffer. This arrangement reduced data transfer volume for the generation of image data which comprises interleaved portions from individual images.

Abstract: A method of generating a plurality of images for display of a 3D scene from different viewpoints comprises generating a model of the scene using a homogenous coordinate system which uses first, second and third orthogonal axes and a homogeneity value. A first display image is obtained from a first viewpoint and one or more further display images are obtained by updating the a coordinate value of the first display image using the displacement value and the homogeneity value. The use of the homogeneity value reduces the complexity of the calculations required to obtain the further images by post processing.
