Abstract

We can enlarge or reduce three-dimensional integral imaging images by using an optical multi-pickup method. We used the moving array- lenslet technique (MALT) to increase the spatial ray sampling rate of elemental images in the optical method. In this paper, we are proposing a digital magnification method to increase the spatial ray sampling rate without lens movement. The major drawback of the optical technique is the complexity due to the small lenslet movement. We used four popular two dimensional (2D) magnified interpolation methods, as: linear, cubic, spline and nearest. We compared the reconstructed integral imaging images using optical and digital magnification methods. When use the optical and digital magnification are used in a sequence, we can reduce the number of pickup procedures for the optical method to a forth while we can see almost the same resolution quality of the reconstructed integral imaging images.
