Abstract: Provided is a method of forming a dynamic maximal viewing zone (DMVZ) of an autostereoscopic display apparatus. The method includes rearranging viewpoint images for each three dimensional (3D) unit pixels of a certain period k when a viewer deviates in a depth direction from a designed viewing distance (DVD), wherein the certain period k is determined according to a distance by which the viewer deviates in the depth direction from the DVD.
