    Multiple Multiperspective Rendering for Autostereoscopic Displays



    Autostereoscopic displays, which do not require special glasses or lighting conditions but use selector screen methods such as parallax barriers, lenticular sheets, and lens arrays, show attractive 3D scenes. However these methods sometimes fail to separate each image because of a lack of display resolution or insufficient lens quality. This disarrangement is more highly visible especially at the viewing areas more distant from the actual display plane, where binocular disparity causes much discrepancy of images. Currently, most graphic designers manage to develop scenes by using heuristic procedures in accordance with the limitations of each display system.
    In the meantime, some research projects have developed multiper- spective rendering to represent artistic images [Singh02] [Seitz03] [Roman04]. These multiperspective methods combine images of different camera parameters into one picture.
    We have developed a method to control camera parameters in accordance with the limitations of autostereoscopic display and com- bines multiple multiperspective images into one 3D image. Each part of an image has an independent weight that controls parallax disparity and exaggerates perspective.
