Abstract
This paper describes a new means to control depth positions of 3-D images for integral photography. A GRIN lens array is set in front of a lens array for image capturing. The length of each elemental GRIN lens composing the array is a half of one period of the optical path. The GRIN lens array also avoids pseudoscopic effects with revised depth. The depth position of the 3-D images is controlled by adjusting the distance between the GRIN lens array and the capturing lens array, thus producing 3-D images without depth distortion.
