Integral videography (IV) is a method for displaying animated 3D autostereoscopic images using a combination of a lens array and a number of calculated elemental images with different perspectives. The advantage of IV is that it can be observed from an arbitrary viewpoint without the use of supplementary glasses or tracking devices. We improved the viewing resolution of IV images with a time-sharing technique that involves placing a pair of rotated prism sheets in front of an IV display. Rotating the pair of prism enables parallel-shifts of the light rays in the 3D space around their original positions. The elemental images are displayed and updated according to the cycle of the rotation. We demonstrated the effectiveness of the method using a set of test patterns and modulation transfer functions.
